Description

Technical field

[0001] The invention relates to a holder for adapting the orientation of a functional element to be held to the steering position of a vehicle with fork steering. The invention further relates to a data carrier, a print data set, and a computer program. It also relates to a vehicle system and a vehicle with fork steering. Devices of the aforementioned type can be used, for example, in the field of automotive engineering, particularly in the field of vehicle safety technology. Thus, the invention can be used, in particular, in road traffic. However, other areas of application are also conceivable in principle. Technical background

[0002] In vehicle safety technology, the orientation of functional elements, particularly optical systems such as lighting or camera systems, and sensors, plays a crucial role, as their orientation is generally decisive for their effectiveness. For example, with regard to vehicle lighting, general safety, such as in road traffic, typically depends not only on whether the vehicle in question can be seen by other road users, but also on the illumination and / or detection of the road surface and surrounding traffic. Especially when driving around curves or corners, the orientation of functional elements, such as optical systems and sensors, which is conventionally determined by the position of a frame or chassis, is typically insufficient for detecting and / or illuminating the road surface.

[0003] Numerous devices are known from the prior art to improve illumination. For example, curve-adaptive headlights are proposed.

[0004] For example, US 982,803 A describes a lamp for a vehicle, with a movable burner, the light of which can be deflected when a vehicle changes direction, especially when cornering.

[0005] US Patent 1,524,443 A describes a device in which the lights automatically rotate with the rotation of the front wheels of a vehicle, so that the light beams are always thrown in front of the vehicle, both when cornering and when driving straight.

[0006] US Patent 3,614,416 A describes a lighting device for road vehicles with a linkage for pivoting the headlight relative to the vehicle's direction of travel and with means that respond to the vehicle's roll to change the inclination of the headlight's pivot axis and to rotate the headlights downward and inward to compensate for the roll. In a modified embodiment, means are used that respond to the vehicle's speed to change the inclination of the headlight's pivot axis when the steering wheel is turned.

[0007] DE 10 2019 006 157 A1 describes a headlight system for a bicycle, e-bike, or e-scooter, comprising a headlight with a housing, several lighting units, and at least two lighting units that can be separately activated and deactivated during operation, such that different beam characteristics can be generated by means of the at least two separately activatable and deactivatable lighting units, and a reflector for reflecting the light emitted by the lighting units, a control and / or regulating unit for switching between the two beam characteristics by means of a radio connection between the control and / or regulating unit and a switching unit, in the event of an interruption of the radio connection between the switching unit and the control and / or regulating unit, glare to oncoming traffic due to the active high beam of the headlight system is avoided, wherein the headlight system, in particular the control and / or regulating unit,is designed in such a way that, in the event of an interruption of the radio connection between the control and / or regulating unit and the switching unit, the headlight system automatically switches to a specific beam pattern.

[0008] DE 20 2016 101 707 U1 describes a headlight for a bicycle, comprising at least one light source whose light can at least partially exit the headlight, wherein the headlight is designed in such a way that the light distribution of the light exiting the headlight can be changed, characterized in that the headlight comprises control means that can change the light distribution of the light emanating from the headlight depending on detected measured values.

[0009] DE 808 027 C discloses a holder for adapting an orientation of a functional element to be held to a steering position of a vehicle with fork steering according to the preamble of claim 1.

[0010] Despite the advantages achieved with the described devices, numerous technical challenges and disadvantages remain. For example, the known devices are generally complex and involve considerable additional weight. For vehicles with fork steering, the vehicle's weight is a crucial factor. Lower weight means easier handling when pushing and less effort when driving. This is particularly important for vehicles without an auxiliary engine, but also for those with an electric motor. Furthermore, the use of complex electronics is prone to failure and can lead to costly repairs. In particular, the known devices typically require additional electronics or components.These additional components, such as prisms or mirrors, additional cables, headlights, sensors and / or light sources, can fail, thus increasing maintenance requirements and raising manufacturing costs and the weight of the device.

[0011] Furthermore, conventional devices generally have high energy consumption, for example, for additional electronics or for brighter illumination of a larger area of ​​the roadway. Particularly with larger-area illumination, a further disadvantage arises: areas adjacent to the roadway, such as those affecting oncoming traffic, are also illuminated. Large-area illumination can therefore generally pose the risk of dazzling other road users, thus reducing the safety of all road users involved. Object of the invention

[0012] It would therefore be desirable to provide devices that largely avoid the disadvantages of known devices. In particular, the devices should be simple, low-maintenance, lightweight, and energy-efficient, while also enabling reliable and safe alignment of functional elements. General description of the invention

[0013] This task is addressed by a holder for adapting the orientation of a functional element to be held to a steering position of a vehicle with fork steering, a data carrier, a print data set, a computer program, a vehicle system, and a vehicle with fork steering, with the features of the independent claims. Advantageous embodiments, which can be implemented individually or in any combination, are described in the dependent claims.

[0014] In the following, the terms "have," "exhibit," "comprise," or "include," or any grammatical variations thereof, are used in a non-exclusive manner. Accordingly, these terms can refer both to situations in which, apart from the features introduced by these terms, no other features are present, and to situations in which one or more additional features are present. For example, the expression "A has B," "A exhibits B," "A comprises B," or "A includes B" can refer both to the situation in which, apart from B, no other element is present in A (i.e., a situation in which A consists solely of B) and to the situation in which, in addition to B, one or more other elements are present in A, such as element C, elements C and D, or even further elements.

[0015] Furthermore, it should be noted that the terms "at least one" and "one or more," as well as grammatical variations of these terms, when used in connection with one or more elements or features and intended to express that the element or feature may be present once or multiple times, are generally used only once, for example, when the feature or element is first introduced. Upon subsequent mention of the feature or element, the corresponding term "at least one" or "one or more" is generally no longer used, without restricting the possibility that the feature or element may be present once or multiple times.

[0016] Furthermore, the terms "preferably," "in particular," "for example," or similar terms are used in the following text in connection with optional features without limiting alternative embodiments. Features introduced by these terms are optional features, and it is not intended that these features limit the scope of protection of the claims, and in particular the independent claims. As the person skilled in the art will recognize, the invention can also be implemented using other embodiments. Similarly, features introduced by "in one embodiment of the invention" or by "in an exemplary embodiment of the invention" are understood as optional features without limiting alternative embodiments or the scope of protection of the independent claims.Furthermore, these introductory expressions are intended to leave all possibilities of combining the features introduced herein with other features, whether optional or non-optional features, unaffected.

[0017] In a first aspect of the present invention, a holder for adapting the orientation of a functional element to be held to a steering position of a vehicle with fork steering is proposed. The holder comprises: - at least one control element, wherein the control element at least partially comprises a steering tube of the fork steering of the vehicle or is directly or indirectly rigidly connectable to the steering tube; - at least one rotating element arranged to rotate relative to the control element; and - at least one holding element connected to the rotating element to which the functional element to be held can be attached.

[0018] The rotary element and the control element are arranged in such a way that a rotary movement of the rotary element caused by a steering movement of the control element causes a movement of the holding element that reinforces the steering movement.

[0019] The term "holder," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a device for supporting and / or securing the functional element. Specifically, the holder may be designed to guide and / or support the functional element in a predetermined path and, depending on a steering position, for example, a steering position of a vehicle with fork steering, to determine the orientation of the functional element, for example, to align the functional element in a predetermined manner. For example, the holder may be purely mechanical, thus fulfilling its function without requiring electrical energy.The holder comprises several elements, which may be mechanically connected, in particular reversibly.

[0020] The term "vehicle with fork steering," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a land vehicle comprising at least two wheels and featuring head tube steering. Thus, the vehicle with fork steering can comprise a frame, in particular a frame including a head tube, as well as a steering tube, for example, a steering tube connected to a fork. In particular, the steering tube, for example, a steering tube connected to the fork via a fork stem or to a swingarm, can be arranged in the head tube of the frame and rotatably mounted therein.The direction of travel in a vehicle with fork steering can be influenced by twisting the steering tube, in particular by turning a handlebar connected to the steering tube. This twisting of the steering tube, for example via the fork, is transmitted to one of the at least two wheels, thereby changing its orientation and / or position.

[0021] The term "control element," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to any component or object whose movement causes and / or dictates the movement of at least one other component or object. For example, the control element can dictate and / or control the position of the rotary element. For example, the control element can comprise the steering tube of the vehicle's fork steering system. In particular, the control element can be the steering tube of the fork steering system. For example, the control element and the steering tube can be integral, in particular formed as a single piece.Alternatively or additionally, the control element can be rigidly connected to the steering tube, for example, by encompassing a surface of the steering tube, or by being connectable to it. Furthermore, alternatively or additionally, the control element can be rigidly connected to the steering tube directly or indirectly, preferably reversibly, for example, directly or indirectly. In particular, the control element can be at least one component or object existing separately from the steering tube, which can be rigidly connected to the steering tube in such a way that a movement of the steering tube also includes a movement of the control element.

[0022] The term "rigidly connectable," as used here, is a broad term to which its ordinary and common meaning, as understood by a person skilled in the art, should be attributed. The term is not limited to a specific or adapted meaning. Without limitation, the term can refer, in particular, to the suitability of an object for being connected to another object without the connection allowing any relative movement between the objects. The rigid connection, especially suitable for force transmission, can, for example, be based on a friction-fit, form-fit, and / or material-fit connection between the objects. Thus, in particular, the control element that can be rigidly connected to the steering tube can be designed to be mounted directly or indirectly to the steering tube by friction, form-fit, and / or material-fit connection.For example, the control element can be attached directly or indirectly to the steering tube by means of a clamp and / or screw connection; a plug connection, a welded or glued connection, or any other connection suitable for force transmission is also possible. A rigid connection of the control element to another object rigidly connected to the steering tube, such as handlebars and / or forks, can also constitute a rigid connection between the control element and the steering tube.

[0023] The terms "connectable to the steering tube" or "connected to the steering tube" or "connectable to the frame" or "connected to the frame," as used here, are broad terms and should be interpreted according to their usual and common meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can mean, in particular, that there is a direct or indirect rigid connection to the steering tube or the frame. For example, the terms "connectable to the steering tube" or "connected to the steering tube" include any rigid connection to the handlebars, the steering fork, the steerer tube, especially to the holes and screws provided for standard bicycle headlights, to a standard bicycle headlight bracket, to a cockpit rigidly connected to the handlebars for accessories, or to other rigidly connected objects.In particular, for vehicles with fork-type steering, a connection can also mean a connection with an Ahead clamp or another clamp in the steering tube. Therefore, a connection to the steering tube exists especially when a rotational movement of the steering tube causes a corresponding rotation of the connected part by the same angle. For example, the terms "connectable to the frame" or "connected to the frame" include a connection to the head tube, to a supporting element.

[0024] For example, the rotating element and the holding element can be integral, in particular formed in one piece. Alternatively or additionally, the holding element can be rigidly connected to the rotating element, preferably reversibly, for example directly or indirectly. Furthermore, alternatively or additionally, the holding element can be connected to the rotating element in such a way that a relative movement in at least one degree of freedom is possible, for example a pivoting movement, for example to adjust an inclination of the functional element.

[0025] The term "steering movement," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to any steering movement that causes the vehicle to travel in a direction other than straight ahead. Specifically, the steering movement of the control element can include a rotation of the steering column to the left or right. For example, the steering movement can be a rotation by an angle α, the so-called steering angle, > 0° clockwise or counterclockwise, relative to a neutral, straight-ahead steering position.The steering movement can refer in particular to a steering movement of the vehicle with fork steering, which is carried out when the vehicle is to drive or execute a curve, for example a left turn or a right turn.

[0026] The term "steering angle," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a rotation of the steering tube by an angle α clockwise or counterclockwise. The term "steering angle range" can refer to a rotation from a steering angle α=α1 to a larger steering angle α=α2, where α1 and α2 describe the same direction of rotation relative to the straight-ahead steering position.

[0027] The rotary element and the control element are arranged in such a way that the rotational movement of the rotary element caused by the steering movement of the control element, particularly about at least one axis of rotation, causes and / or controls a movement of the retaining element that reinforces the steering movement. In this context, the term "movement reinforcing the steering movement" can refer in particular to a rotation, for example a rotary movement, by an angle β > α, the so-called alignment angle of the functional element. In particular, the control element and the rotary element, as well as the retaining element connected to the rotary element, can be arranged such that a rotation of the steering tube, starting from a neutral, straight-ahead steering position, by the angle α clockwise or counterclockwise causes a rotation of the retaining element by the angle β, also clockwise or counterclockwise, where β > α.The arrangement of the holder's elements, particularly the arrangement of the control element, the rotary element, and the retaining element, can, for example, cause a functional element attached to the retaining element to rotate from its original orientation by α > 0° in a direction that amplifies the steering movement in the same direction as the steering movement itself. Thus, a clockwise steering movement can be amplified clockwise, while a counterclockwise steering movement can also be amplified counterclockwise. If the retaining element is connected to the steering tube via the rotary element, it performs part of its rotation in conjunction with the steering movement around the steering angle. To achieve a rotation of the retaining element by the angle β, the rotary element can perform a rotation approximately by the angle β-α.

[0028] In particular, the rotating element can be arranged such that it performs the rotational movement about a vehicle frame or about at least one support element rigidly connected to the frame. The rotating element can thus be arranged such that it can perform a rotational movement about the vehicle frame, in particular about an axis of rotation spatially fixed relative to the vehicle frame. The at least one axis of rotation of the rotating element can, in particular, be oriented perpendicular to a direction of travel of the vehicle with fork steering. If the retaining element is connected to the frame via the rotating element and the support element, it does not perform part of its rotation with the steering angle. To achieve a rotation of the retaining element by the angle β, the rotating element can perform a rotation approximately by the angle β.

[0029] For example, the rotating element can be mounted around the control element, such that movement between the rotating element and the control element is at least restricted in at least three degrees of freedom, in particular in at least four degrees of freedom, for example in five degrees of freedom. Alternatively, the rotating element can be mounted around the support element, such that movement between the rotating element and the support element is at least restricted in at least three degrees of freedom, in particular in at least four degrees of freedom, for example in five degrees of freedom.

[0030] The holder can further comprise at least one transmission element for transferring the movement, in particular the steering movement, of the control element to the rotary element. Thus, a rotary movement of the rotary element, which is mounted on the support element, for example, can be controlled and / or caused by the movement of the control element, particularly by means of the transmission element. For example, a rotation of the control element, i.e., the steering movement, can be transferred to the rotary element by means of the transmission element.

[0031] The at least one transmission element can be configured, in particular, to transmit a rotary motion from the control element to the rotary element. For example, the transmission element can be selected from the group consisting of: a gear; a friction wheel; a toothed disc; a chain, for example, a toothed chain; a belt, for example, a toothed belt; a cord; an elastic band; a Bowden cable; a Bowden cable core; a Bowden cable housing; a band; a bevel gear; a bevel friction wheel; a sector of a bevel gear; a sector of a bevel friction wheel; a toothed rail; or a cardan shaft. Various tooth shapes are possible, such as curved teeth, herringbone teeth, or double helical teeth. The transmission element can also be designed as a hydraulic transmission element. The at least one transmission element can have its own axis of rotation. However, this is not mandatory.For example, by using deflections and bearings, a transmission element in the form of a pulley-like construction can also change the transmission ratio. Other mechanical elements can also be used as transmission elements to transfer motion.

[0032] The holder can be designed as a planetary gear set. In particular, the holder can be designed as a planetary gear set. In this case, the control element can be designed as the planet carrier, the rolling element as the sun gear, several transmission elements can be designed as planet gears, and the rotating element can be designed as a ring gear. Planetary gear sets allow for a compact design and exhibit low imbalance. In this case, the planet gears ensure smooth running and are automatically held between the sun and ring gears. Alternatively, the rolling element can be designed as the ring gear and the rotating element as the sun gear.

[0033] The term "Bowden cable," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can encompass a Bowden cable core that can move axially within the Bowden cable housing. In particular, the Bowden cable core and housing can only undergo small changes in length in the axial direction; they are both flexible transversely to the axial direction. Since the force required to transmit the axial movement of the Bowden cable core within the housing is comparatively small, the housing can be made of various materials, such as a plastic tube or hose, or of a material commonly used, for example, for gearshift or brake cables in vehicles with forked steering systems.The Bowden cable core can be a wire, strand, cord, fishing line, rope, or similar material. The Bowden cable can be attached at one end and designed for both tension and compression. In this case, the Bowden cable can be used to rotate the rotating element clockwise or counterclockwise. Alternatively, the Bowden cable can be attached at both ends and designed for tension. In this case, one Bowden cable can be used to rotate the rotating element clockwise, and the other Bowden cable for counterclockwise rotation. In both cases, the materials and diameters are matched so that the Bowden cable core moves largely axially within the Bowden cable housing. Alternatively, a Bowden cable attached at both ends can also be designed so that it encloses a Bowden cable housing that undergoes a change in length against a restoring force.In this case, a pre-tensioned compression spring, for example, can be used as the material. With this setup, a Bowden cable can be used to achieve a transmission ratio that depends on the steering angle.

[0034] The control element can, in particular, be at least partially finger-shaped. The term "finger-shaped," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to a specific or adapted meaning. Without limitation, the term can refer, in particular, to an elongated shape or form similar to a finger. Thus, a finger-shaped part of the control element can, for example, resemble a finger. In particular, the rotating element can be arranged concentrically around the finger-shaped part of the control element, such that a movement of the control element causes a movement of the axis of rotation of the rotating element.In particular, the axis of rotation can, for example, be an axis in the center of the finger-shaped part of the control element, such as a part of the finger perpendicular to the direction of travel. For example, the finger-shaped part of the control element can also be bent and / or angled at least one angle, for example at right angles, in particular such that the axis of rotation of the rotary element is oriented perpendicular to a direction of travel of the vehicle with fork steering.

[0035] The rotational movement of the rotating element can, for example, be a rolling movement relative to the frame or relative to a rolling element that can be connected to the frame, in particular to the frame of a vehicle with fork steering. For instance, the rotating element can roll over a surface of the frame, in particular performing a rotational movement as a rolling movement over the surface of the frame. Alternatively or additionally, the rotating element can roll over at least one surface of the rolling element, in particular performing a rotational movement as a rolling movement over a surface of the rolling element. The rolling element can be connected to the frame, for example, rigidly attached to the frame or stretched across the frame. In particular, the rolling element can be arranged and attached on and / or around the surface of the frame.The rolling element can be, for example, an object rigidly connected to the frame and an element selected from the group consisting of: a gear, for example, a toothed ring forming at least one pitch circle; a friction wheel, for example, a friction ring forming at least one pitch circle and having a friction surface; a toothed disc; a chain, for example, a toothed chain; a bevel gear; a bevel friction wheel; a sector of a bevel gear; a sector of a bevel friction wheel. Various tooth shapes are possible, such as curved teeth. The rolling element can be designed, in particular, as a complementary counterpart to the rotating element. Alternatively or additionally, the rolling element can also be movable, for example, as a component without its own axis of rotation, as a Bowden cable, Bowden cable core, Bowden cable housing, fishing line, wire rope, strand, cord, tape, or belt.Other designs of the rolling element that allow for a rolling motion of the rotating element are also conceivable. In principle, any shape that allows for interlocking is suitable. A rolling element can, in particular, be a component without its own axis of rotation.

[0036] For example, the rotating element can be selected from the group consisting of: a gear, for example, a pitch circle with at least three teeth, a sector of a gear, a half gear, and / or a gear with a constant or position-varying diameter; a friction wheel, for example, a friction wheel designed as a pitch circle, a sector of a friction wheel, a half friction wheel, and / or a friction wheel with a constant or position-varying diameter; a toothed disc, for example, a toothed disc with at least three teeth, a sector of a toothed disc, a half toothed disc, and / or a toothed disc with a constant or position-varying diameter; a bevel gear; a bevel friction wheel; a sector of a bevel gear; a sector of a bevel friction wheel. Various tooth shapes are possible, such as curved, herringbone, or double helical teeth.Basically, any shape that allows for interlocking is suitable.

[0037] In particular, a rotational position of the rotating element, in a predetermined transmission ratio, can correspond to the steering position of the steering tube about a steering axis relative to the vehicle frame. Thus, in particular, twisting the steering tube relative to the frame, for example, in the steering tube and about the vehicle's steering axis, can cause the rotating element to rotate according to a predetermined transmission ratio. The term "transmission ratio," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to a specific or adapted meaning. Without limitation, the term can refer, in particular, to a value of a mathematical relationship between mutually influencing movements of at least two objects, for example, encompassing a ratio of input to output.In particular, a transmission ratio between a rotational position of the rotating element and a steering position of the steering tube can refer to a ratio between two angles, wherein a first angle can be defined between the steering position of the steering tube and the straight-ahead steering position of the steering tube, and wherein the second angle can be defined between a rotational position of the rotating element at both the steering position of the steering tube and the straight-ahead steering position of the steering tube. The transmission ratio i can comprise a quotient of the angles α and β, for example, i = β / ct. In particular, the transmission ratio i can be > 1 such that a movement of the steering tube, especially a rotation of the control element, e.g., the steering movement, is smaller than the resulting rotation of the rotating element and / or the retaining element connected to the rotating element. For example, 3 > i > 1.1, in particular 2.5 > i > 1.2.

[0038] For example, the transmission ratio can be constant. Alternatively, a variable transmission ratio is also possible. The transmission ratio can, for instance, depend on the rotational position of the rotary element. In this case, at least one of the elements of the control element and the rotary element can have a radius that changes along its circumference, for example, a changing distance between the contact point and the axis of rotation. Thus, the control element and / or the rotary element can have an oval or egg-shaped form and / or a form with a stepped change in radius. For example, the transmission ratio can be higher at small steering angles than at large steering angles. This ensures that the functional element is sufficiently aligned with the curve at small steering angles without being excessively aligned with the curve at large steering angles.For example, it is advantageous to achieve a transmission ratio of >2, preferably >2.5, at small steering angles and simultaneously to limit the orientation of the functional element to <180° at large steering angles of 90°. Constant transmission ratios can be achieved in specific steering angle ranges using components selected from the group consisting of a control element, a rotary element, a rolling element, and / or a transmission element. In particular, the movement of the retaining element, which is amplified by the steering movement of the control element, can depend on the steering position of the steering tube. The amplified movement of the retaining element is greater, especially in a steering angle range of 1° to 25°, than in a steering angle range of 45° to 90°, and in particular, within a portion of a steering angle range, exhibits a constant transmission ratio between the rotational movement of the rotary element and the rotational movement of the steering tube.A gear ratio of >2, preferably >2.5, is particularly advantageous in a section of the steering angle range from 1° to 25°. A gear ratio of <2, preferably <1.8, is particularly advantageous in a section of the steering angle range from 45° to 90°.

[0039] On vehicles with fork-type steering, the steering axis is tilted backwards relative to the vertical. This so-called trail is geometrically determined by the wheel radius, the steering head angle between the steering head axis and the ground, and the fork flex, i.e., the perpendicular distance from the hub to the steering head axis. Trail is an important structural feature in preventing tipping over while driving straight. The tilt of the steering axis on road bikes relative to the vertical is approximately 15° to 30° backwards. This is because a smaller steering head angle improves directional stability. For a functional element with a predetermined tilt in space, the distance between the intersection of an imaginary extension of the tilt with a surface on the vehicle and the intersection of a projection of the functional element perpendicular to a surface on the vehicle depends on the steering position.In particular, this distance decreases with increasing steering angle α. While driving, single-track vehicles with fork steering lean inwards when cornering, depending on the vehicle speed. The reduction of the described distance is further amplified in a fork-steered vehicle leaning into a curve. This distance represents, in particular, the functional range of the functional element. The described reduction of the distance results in a reduction of the functional range of the functional element. For example, the functional element could be a lamp. In vehicles with fork steering, a lamp is usually rigidly connected to the steering column and has a predetermined tilt in space, such as 5° downwards, to avoid dazzling oncoming traffic.Due to a rearward-tilting steering axis, the functional range, in the form of the light range, depends on the steering column's position and decreases with increasing steering angle. If the steering axis and the axis of rotation of the functional element-holding rotating element are aligned parallel, the reduction of the described distance or functional range increases with increasing steering angle. In particular, the axis of rotation of the functional element-holding rotating element can be inclined forward relative to the steering axis, preferably forward relative to the vertical, thereby reducing the reduction of the described distance. For example, the axis of rotation of the functional element-holding rotating element can be inclined forward such that, within a steering angle range of 1° to 75°, the reduction of the described distance is limited to a maximum of 75%, preferably a maximum of 60%, when the vehicle is upright.The term "upright vehicle" describes a situation where the vehicle is not tilted inwards when cornering, e.g. for the limit of a driving speed of 0 km / h.

[0040] In particular, the axis of rotation of the rotary element holding the functional element can be tilted forward by 15° to 40° or 60° to 80° relative to the vertical, preferably inclined. The reduction of the described distance caused by the amplifying movement of the holding element resulting from a steering movement of the control element can be compensated for in such a way that the reduction of the described distance is less than with a transmission ratio of approximately 1, i.e., with a functional element that is mounted without a holder according to the invention.

[0041] In particular, the holder can be manufactured wholly or partially by at least one additive manufacturing process, for example on an additive manufacturing device, such as by at least one 3D printing process and / or by plastic laser sintering. Alternatively or additionally, other materials and / or manufacturing processes are also possible, for example metallic materials and / or composites.

[0042] The term "additive manufacturing device," as used here, is a broad term to which its usual and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a manufacturing module and / or a manufacturing system that is set up to produce three-dimensional objects, such as workpieces and / or components, from one or more liquid and / or solid materials by means of a computer-controlled, layer-by-layer process. The additive manufacturing device can also be referred to as a 3D printer. The additive manufacturing device may include an interface, such as an STL interface, in particular for data transmission, for example, to read information and / or instructions stored on a data carrier.

[0043] Contact points of the functional element-holding rotary element with a rolling element and / or with a transmission element and / or with the control element can, when projected onto a plane perpendicular to a steering axis of the steering tube, describe a steering angle-dependent radius. Alternatively, contact points of the control element with a rolling element and / or with a rotary element and / or with a transmission element can, when projected onto a plane perpendicular to a steering axis of the steering tube, describe a steering angle-dependent radius.

[0044] Contact points of the rotating element with the rolling element and / or with a transmission element and / or the control element can, when projected onto a plane perpendicular to its own axis of rotation, describe a steering angle-dependent radius. This is possible, for example, if the rotating element has steering angle-dependent radii, such as if it is elliptical. Alternatively, contact points of the control element with a rolling element and / or with a rotating element and / or with a transmission element can, when projected onto a plane perpendicular to its own axis of rotation, describe a steering angle-dependent radius.

[0045] This is possible, for example, if the control element has steering angle-dependent radii, for example, if it is elliptical in shape.

[0046] A contact point is the point on a component where the component touches another component, such as a rotating element touching a rolling element.

[0047] The transmission element can be movable in such a way that, at least in one range of steering angles, a steering angle-dependent transmission ratio results.

[0048] In particular, the axis of rotation of the pivoting element is tiltable relative to at least one steering axis of the steering tube, especially tilted forwards. The tiltability of the pivoting axis is designed such that its inclination can be adjusted to set the function of the functional element. During driving, the inclination of the pivoting element's axis of rotation relative to the steering axis can remain constant.

[0049] In a further aspect of the present invention, a data carrier containing instructions is proposed which, when executed on an additive manufacturing device, in particular a 3D printer, causes the additive manufacturing device to produce a holder of the present invention, i.e., according to one of the embodiments mentioned above or according to one of the embodiments described in more detail below. Accordingly, for definitions and optional configurations, reference can largely be made to the description of the holder. However, other configurations are also possible in principle.

[0050] The term "data carrier," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to at least one non-transient data storage device, for example, a hardware data storage medium on which computer-executable instructions are stored. In particular, the instructions on the data carrier can be stored as a data structure which, after being loaded into the working and / or main memory of an additive manufacturing device, causes it to produce the holder according to the invention. The data carrier can also be referred to in particular as a "computer-readable data carrier."In particular, the data carrier can be or comprise a storage medium readable by the additive manufacturing device, such as a Random-Access Memory (RAM) and / or a Read-Only Memory (ROM).

[0051] In particular, the instructions stored on the data carrier can define operating instructions for the additive manufacturing device, for example, for controlling the device. Furthermore, the data carrier, especially in the instructions, can include a digital representation of the holder. For example, a data carrier with instructions can be proposed where the instructions define both a digital representation of the holder described herein and include operating instructions adapted, for example, for controlling the additive manufacturing device, with which the holder can be manufactured using the digital representation of the holder when the instructions are forwarded to the additive manufacturing device.

[0052] For example, the instructions on the data carrier can be in the form of a 3D file, such as in STL, DXF, VRML, OBJ, 3DS, OFF, AMF, 3MF, or similar file formats readable by additive manufacturing devices. Alternatively or additionally, the instructions on the data carrier can be in the form of a layer file, such as a CLI file, SLC file, or similar file format, containing comprehensive information on a multitude of cutting contours for the layer-by-layer fabrication of the holder in the additive manufacturing device.

[0053] In a further aspect of the present invention, a print data set is proposed. This print data set comprises information which, when provided to an additive manufacturing device, causes the device to produce a holder of the present invention, i.e., according to one of the embodiments mentioned above or according to one of the embodiments described in more detail below. Accordingly, for definitions and optional configurations, reference can largely be made to the description of the holder. However, other configurations are also fundamentally possible.

[0054] The term "print data set," as used here, is a broad term and should be understood in its usual and common sense, as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer, in particular, to data containing information for the production of a three-dimensional object in the additive manufacturing device, such as operating instructions. Specifically, the print data set can include instructions on how to control a print head of the additive manufacturing device and / or how much material to apply per layer. For example, the print data set may be in G-code format. The print data set may also be tailored to a specific additive manufacturing device, such as a particular type and / or manufacturer.

[0055] In a further aspect of the present invention, a computer program is proposed. The computer program comprises instructions which, when executed on a computer, cause the computer to generate a print data set according to the preceding claim. Accordingly, for definitions and optional embodiments, reference can largely be made to the description of the print data set. However, other embodiments are also fundamentally possible.

[0056] In particular, the instructions of the computer program, for example, the instructions present or stored in the computer program, can include a digital representation of the holder, especially the holder according to the invention and described herein, i.e., according to one of the embodiments mentioned above or according to one of the embodiments described in more detail below. The digital representation of the holder can, in particular, include a 3D model of the holder. For example, the computer program can be configured to create and / or generate the print data set from the digital representation of the holder.

[0057] In a further aspect of the present invention, a vehicle system is proposed. The vehicle system comprises a holder according to the invention and the functional element to be held. The functional element to be held is selected from the group consisting of: a lamp, for example an electrically operated lamp, such as a flashlight or a lamp powered by a dynamo, a light, a bicycle headlight; a sensor, for example a distance sensor, a camera sensor. For definitions and optional embodiments, reference can largely be made to the description of the holder. However, other embodiments are also possible in principle.

[0058] The term "vehicle system," as used here, is a broad term to which its ordinary and common meaning, as understood by those skilled in the art, should be attributed. The term is not limited to any specific or adapted meaning. Without limitation, the term can refer in particular to a unit associated with a single vehicle and composed of at least two components, wherein the components are configured to work together functionally to achieve at least one purpose of the system. The components may be mechanically connected to one another, in particular reversibly. The vehicle system can, in particular, serve to align the functional element according to a steering position of a vehicle with fork steering, for example, such that the functional element performs an enhanced steering movement.

[0059] In a further aspect of the present invention, a vehicle with fork steering is proposed, in particular a vehicle which has fork steering. The vehicle with fork steering comprises a frame, a steering tube rotatable about a steering axis relative to the frame, and a holder and / or a vehicle system according to the invention. Accordingly, for definitions and optional embodiments, reference can largely be made to the description of the holder and / or the vehicle system. However, other embodiments are also possible in principle.

[0060] The vehicle can be a two-wheeler or three-wheeler. For example, the vehicle can be selected from the following groups: bicycle, e-bike, electric bicycle, pedelec, moped, light motorcycle, motorcycle, scooter, electric scooter, e-scooter, motorcycle, cargo bike, or trike. Other two- or three-wheelers are also generally acceptable.

[0061] The proposed devices offer numerous advantages over devices known from the prior art. In particular, safety, for example in road traffic, can be significantly improved compared to the prior art. Furthermore, a reduction in manufacturing and assembly complexity is possible due to a more robust design, while simultaneously reducing energy consumption and costs.

[0062] The proposed devices, particularly those comprising a lamp, enable illumination of only the portion of the road necessary for the driver of the fork-steered vehicle and other road users. This significantly reduces or eliminates glare and / or light pollution. Unlike conventional vehicle systems whose headlights illuminate the oncoming lane, the proposed devices, especially the mounting bracket and vehicle system, ensure that only the lane and / or road intended for travel by the fork-steered vehicle—for example, the lane in the vehicle's direction of travel—is illuminated.

[0063] Further safety enhancements through the proposed devices can be achieved, for example, by illuminating the area of ​​the roadway in the direction of travel when cornering, i.e., when driving through a left or right turn. This contrasts with conventional devices, which generally illuminate an area beside the roadway when cornering. The proposed devices can therefore very efficiently direct the light intensity according to the vehicle's direction of travel, thereby increasing safety while simultaneously reducing energy consumption. Brief description of the characters

[0064] Further details and features will become apparent from the following description of exemplary embodiments, particularly in conjunction with the dependent claims. The respective features may be implemented individually or in combination with one another. The invention is not limited to the exemplary embodiments but is defined solely by the appended claims. The exemplary embodiments are shown schematically in the figures. Identical reference numerals in the individual figures denote identical or functionally equivalent elements, or elements that correspond to one another with respect to their functions.

[0065] Specifically, we show: Fig. 1 and Fig. 2. A section of an embodiment of a vehicle with fork steering with different steering positions, an embodiment of a vehicle system, and an embodiment of a holder in top view; and Fig. 3 to 16 different embodiments of a holder, a vehicle system and a vehicle with fork steering in perspective views; Fig. Figure 17 shows a perspective bottom view of the control element, the rotary element, and the projection of contact points of the rotary element into the plane perpendicular to the steering axis; and Fig. 18 exemplary curves of the luminous range when the functional element is designed as a headlight or lamp, depending on the luminous angle at different inclinations of the axis of rotation of the rotating element holding the functional element relative to the vertical. Description of the exemplary implementations

[0066] Fig. 1 and Fig. Figure 2 shows a section of an embodiment of a vehicle 110 with fork steering in a top view. The vehicle 110 with fork steering comprises a frame 112 and a steering tube 116 rotatable about a steering axis 114 relative to the frame 112. The vehicle 110 with fork steering further comprises a holder 118 for adapting the orientation 134 of a functional element 120 to be held to a steering position of the vehicle 110 with fork steering. Alternatively or additionally, the vehicle 110 with fork steering comprises a vehicle system 122 comprising the holder 118 and the functional element 120.

[0067] The holder 118 comprises a control element 124, wherein the control element 124 at least partially comprises the steering tube 116 of the fork steering of the vehicle 110 or is rigidly connectable to the steering tube 116. Furthermore, the holder 118 comprises at least one rotary element 126 rotatably arranged relative to the control element 124, and at least one retaining element 128 connected to the rotary element 126, to which the functional element 120 to be held can be attached. The rotary element 126 and the control element 124 are arranged such that a rotational movement of the rotary element 126 caused by a steering movement of the control element 124 results in a movement of the retaining element 128 that amplifies the steering movement.

[0068] Fig. Figure 1 shows a section of the vehicle 110 with fork steering in a straight-ahead steering position. In the straight-ahead steering position, a direction axis 130 can correspond to a frame alignment axis 132 and / or be arranged parallel to the frame alignment axis 132. Furthermore, in the straight-ahead steering position, the orientation 134 of the functional element 120 can also be aligned parallel to the direction axis 130 and / or the frame alignment axis 132.

[0069] Fig. 2 shows the same embodiment as in Fig. 1 with a steering position turned to the left, in particular after performing a counterclockwise steering movement. The steering movement that leads to the illustrated left-turned steering position can, for example, include a rotation of the steering tube 116 relative to the frame 112 by an angle α 136, where α > 0°. The same steering movement of the steering tube, through the arrangement of the rotary element 126 and the control element 124, leads to a movement of the retaining element 128 that amplifies the steering movement, so that the functional element 120, which can be attached to the retaining element 132, can rotate its orientation 134 by an angle β 138 counterclockwise, where β > α.

[0070] In the Fig. Figures 3-10 show different embodiments of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in perspective views. In particular, the rotating element 126 can be arranged such that it performs the rotational movement about the frame 112 of the vehicle 110, as shown, for example, in the Fig. Figures 3-9 show that, for example, the control element 124 can be at least partially finger-shaped. In particular, the rotary element 126 can be arranged concentrically around the finger-shaped part of the control element 124, such that a movement of the control element 124 causes a movement of the axis of rotation 139 of the rotary element 126. The rotary element 126 can also be arranged, for example, such that it performs the rotational movement about at least one support element 140 that is rigidly connected to the frame 112, as shown, for example, in Fig. 10 shown.

[0071] The holder 118 can further comprise at least one transmission element 142 for transmitting the movement of the control element 124 to the rotary element 126. The transmission element 142 can, in particular, be a gear. Such an embodiment is shown by way of example in Fig. 10 shown.

[0072] Alternatively or additionally, the rotary motion of the rotating element 126 can also be a rolling motion relative to the frame 112 or relative to a rolling element 144 that can be connected to the frame 112. For example, the rolling element 144 can be designed as a complementary counterpart to the rotating element 126. Thus, for example, the rolling element 144 and the rotating element 126 can form a rolling pair. For example, the rotating element 126 can be designed at least partially as a gear and the rolling element 144 at least partially as a toothed ring. Exemplary illustrations of such toothed pairings of the rotating element 126 and the rolling element 144 are shown in the Fig. 3, Fig. 6, Fig. 7 and Fig. Figure 8 shows that, alternatively or additionally, the rotating element 126 can be designed partially as a friction wheel and the rolling element 144 at least partially as a friction ring. An exemplary illustration of such a friction pairing of the rotating element 126 and the rolling element 144 is shown in Figure 8. Fig. 9 shown. Alternatively or additionally, the rolling element 144 can also be designed as an elastic band, as exemplified in Fig. Figure 5 shows that if the rolling element 144 is not rigidly connected to the frame 112, it can act as a transmission element 142. In this case, the frame itself is the rolling element 144, on which the transmission element 142 rolls. A design without a rolling element 144 is also possible. For example, a rotary element 126 equipped as a friction wheel can roll directly over a surface of the frame 112, as shown in Figure 5. Fig. 4 shown.

[0073] Fig. Figure 11 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering, with or without a spring fork, in a perspective view. The differences from the previous embodiments are described in particular, and identical or comparable components are identified with the same reference numerals. In the [reference to the] Fig. In the embodiment shown in Figure 11, the steering tube 116 is designed as a control element 124 and a transmission element 142 as a Bowden cable comprising a Bowden cable core 146 and a Bowden cable sheath 148. The Bowden cable core 146 is rigidly connected to the steering tube 116 and the rotary element 126, which includes the retaining element 128, at the attachment points 162 and 163, respectively. The Bowden cable core 146 is movably guided within the Bowden cable sheath 148. A support element 140 is rigidly connected to the frame 112 and further comprises a first receptacle 152 for the Bowden cable sheath 148 and a first guide 165 for the Bowden cable core 146, which is designed for both push and pull. The rotary element 126 is rotatably arranged on a rotary element holder 150, which is rigidly connected to the vehicle with fork steering. The rotary element holder 150 also includes a second receptacle 153 for the Bowden cable housing 148 and a second guide 165' for the Bowden cable core.The Bowden cable core 146 is located only on one side with respect to the pivot axis 139 or the steering axis 114. In particular, a rotational position of the pivot element 126, in a predetermined transmission ratio, can correspond to the steering position of the steering tube 116 about the steering axis 114 relative to the frame 112 of the vehicle 110. With this design, in particular, a rotation of the steering tube 116 about the steering axis 114 relative to the frame 112, for example the steering tube of the vehicle 110, can cause a rotation of the pivot element 126 according to a predetermined transmission ratio.

[0074] Fig. Figure 12 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. The differences from the previous embodiment are described in particular, and identical or comparable components are marked with the same reference numerals. In the Fig. In the embodiment shown in Figure 12, the control element 124, which is directly or indirectly connected to the steering tube 116, comprises the first receptacles 152, 152' for two Bowden cable housings 148 and 148'. The embodiment includes the frame 112, for example a steering tube, as a roller element 144. The roller element 144 is connected to the two Bowden cable cores 146, 146' at the attachment points 162, 162', each of which is designed as a cable. The transmission elements 142 and 142' are designed as two Bowden cables, comprising the two Bowden cable cores 146 and 146', each of which is movably guided in the Bowden cable housings 148, 148' and is connected to the rotary element 126, which includes the retaining element 128, at the attachment points 163, 163'. The rotating element 126 is rotatably arranged on a rotating element holder 150 and contains the second receptacles 153, 153' for the two Bowden cable housings 148, 148'.Alternatively, it can also be a continuous Bowden cable core 146, which is slidable within both Bowden cable housings 148, 148'. The pivot element holder 150 is rigidly connected to the vehicle with fork steering. The Bowden cable cores 146, 146' are located on opposite sides with respect to the pivot axis 139 and the steering axis 114, respectively; that is, the Bowden cables are arranged on both sides of the pivot axis 139 and the steering axis 114, respectively, meaning the Bowden cables are always under tension. The advantage of the double-sided arrangement of the Bowden cable is that it is essentially a closed cable system. Therefore, firstly, the Bowden cable core is always in contact with the rotating element and does not require guidance; secondly, the Bowden cable housings 148, 148' do not even need to be rigidly connected to the housing receptacles.As an alternative to the figures shown, the Bowden cable cores can also wrap around the frame more than once to reduce the risk of slippage, especially if the Bowden cables are clamped to the frame or steering and not screwed in place.

[0075] The in Fig. The embodiment shown in 11 can also be implemented with two Bowden cables designed for tension, running parallel to each other. The [description of embodiment] Fig. The embodiment shown in 12 can also be implemented with a Bowden cable laid in a crisscross pattern, designed for both tension and push.

[0076] The implementation can be carried out on a vehicle with or without a suspension fork. This is particularly relevant in the case of the... Fig. In the embodiment shown in Figure 12, with two Bowden cables laid crosswise, the distance from the first to the second holder does not change in a vehicle without a spring fork, so that alternatively the Bowden cable housings can be dispensed with.

[0077] In the embodiments of the Fig. 11 and Fig. In figure 12, the pivot holder 150 is connected to the steering tube 116. Alternatively, the pivot holder 150 can also be connected to the vehicle frame. In this case, the pivot holder does not move with the steering system itself, so the diameter of the pivot element is different compared to the illustrations in the Fig. 11 and Fig. 12 can be reduced in size to obtain the corresponding translation ratios.

[0078] Fig. Figure 13 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. The differences from the previous embodiments are described in particular, and identical or comparable components are identified with the same reference numerals. In the Fig. In the embodiment shown in 13, the holder 118 is designed to change the transmission ratio. The Fig. The embodiment shown in 13 represents in particular a modification of the one described in Fig. The embodiment shown in 10 is represented and can be provided in a similar manner in other embodiments. The holder 118 of the embodiment shown in 10 is also represented in the following embodiments. Fig. In the embodiment shown in Figure 13, at least one transmission element 142 is used to transmit the motion of the control element 124 to the rotary element 126 connected to the holding element 128. The transmission element 142 is, in particular, a gear or a friction wheel. The transmission element 142 can be used to adjust the transmission ratio because it uses two different diameters. This allows for a more compact design. The transmission element 142 comprises a first gear or friction wheel 166 with a first diameter and a second gear or friction wheel 166' with a second diameter. The first gear or friction wheel 166 and the second gear or friction wheel 166' are connected to each other at their facing axial end faces or are formed integrally. In any case, the first and second gears or friction wheels 166, 166' are arranged on a common axis of rotation 168.The first diameter differs from the second diameter. In the illustrated embodiment, the first diameter is smaller than the second diameter. The first gear or friction wheel 166 engages with the control element 124, and the second gear or friction wheel 166' engages with the rotary element 126. Optionally, the axes of rotation can be inclined relative to each other by designing the gears or friction wheels as bevel gears or bevel friction wheels.

[0079] Fig. Figure 14 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. The differences from the previous embodiment are described in particular, and identical or comparable components are marked with the same reference numerals. For better illustration of the various parts, the control element 124 and the rotary element 126 are shown shifted in the vertical direction. In the Fig. In the embodiment shown in Figure 14, the frame 112 has a spring fork 154 with a swingarm 156. The transmission elements 142 and 142' are designed as Bowden cables, comprising two Bowden cable cores 146, 146' and two Bowden cable housings 148, 148'. The control element 124 includes a clamp 160, which is inserted into the steering tube 116 from below and connected to it from the inside, and two first receptacles 152, 152' for the Bowden cable housings 148 and 148'. The rotary element 126, connected to the retaining element 128, is rotatably mounted on a rotary element holder 150, which contains the second receptacles 153, 153' for the two Bowden cable housings 148, 148'. The rotating element holder 150 is indirectly and rigidly connected to the swing arm 156 via a commercially available holder for a bicycle headlight.The two Bowden cables 146, 146' are guided diagonally and connected to the roller element 144 at one or more first attachment points 162, 162'. The roller element 144 is designed as a frame 112, a head tube, or a clamp connected to the head tube. The second ends of the Bowden cables 146, 146' are each connected to one or more second attachment points 163, 163' on the rotary element 126. The rotary element holder 150 has at least one first stop 164, e.g., in the form of a pin. The rotary element has at least one second stop 164'. The stops 164, 164' are designed to limit the movement of the rotary element 126 up to a certain rotation of the rotary element, preferably <80°. With a transmission ratio of approximately i=2, the limit is reached at a steering angle of approximately α=40°.The Bowden cable housings are designed to have a restoring force, for example, by being configured as tensioned compression springs, such as a coil spring, in which the Bowden cable cores 146, 146' run, and undergoing an axial change in length at larger steering angles. This change in length results in a transmission ratio that depends on the steering position and is smaller at larger steering angles than at smaller ones. The compression spring must be designed to provide sufficient restoring force so that the change in length of the Bowden cable housing occurs when it contacts the two stops 164 and 164'.

[0080] For example, the Bowden cable cores can be rerouted at the positions marked 163, 163' on the rotary element and attached to the rotary element holder on the opposite side. This allows the transmission ratio to be changed and a more compact design of the rotary element holder and rotary element to be achieved.

[0081] Fig. Figure 15 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. The differences from the previous embodiments are described in particular, and identical or comparable components are marked with the same reference numerals. In the Fig. In the embodiment shown in Figure 15, the holder 118 is designed as a planetary gear 170, such as a planetary gear 172. The control element 124 is designed as a planet carrier connected to the steering tube 116. The control element 124 has a rolling element 144, which is designed as a sun gear. The rolling element 144 is arranged, for example, on the frame 112 in the form of a toothed ring. Furthermore, several transmission elements 142 are designed as planet gears. The rotating element 126 connected to the holding element 128 is designed as a ring gear with at least one internal tooth.

[0082] Holder 118 of the in Fig. The embodiment shown in Figure 15 can also be configured to change the transmission ratio. The transmission element 142 comprises a first gear 166 with a first diameter, a second gear 166' with a second diameter, and a third gear 166" with a third diameter. The first gear 166, the second gear 166, and the third gear 166" are connected to one another at their facing axial end faces or are formed integrally. In each case, the first gear 166, the second gear 166', and the third gear 166" are arranged on a common axis of rotation 168. The three gears 166, 166', 166" are of different sizes, with the second gear 166' being larger than the third gear 166". Preferably, the first gear is smaller than the second and larger than the third gear. The first gear 166 engages with the rolling element 144. The rotating element 126 has a first internal toothing 174.The rotating element 126 also has a second internal toothing 174'. The second internal toothing 174' is offset from the first internal toothing 174 axially with respect to the steering axis 114 and circumferentially around the steering axis 114. Depending on the steering angle, the second gear 166' engages with the first internal toothing 174 of the rotating element 126, or the third gear 166" engages with the second internal toothing 174' of the rotating element 126. Accordingly, different gears engage on the planetary gear depending on the steering position. This changes the gear ratio depending on the steering position. For example, the teeth 166' and 174 engage at small steering angles, and the teeth 166" and 174' engage at large steering angles, so that the gear ratio is higher at small steering angles than at large steering angles.

[0083] Alternatively, the planetary gear set can also be designed such that the rolling element is a ring gear, the rotating element a sun gear, and the planet carrier a control element, with several transmission elements designed as planet gears. Alternatively, the planetary gear set can also be designed such that the control element is a sun gear and the rotating element a ring gear. Further alternative embodiments of a planetary gear set are also possible.

[0084] Fig. Figure 16 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. The differences from the previous embodiments are described in particular, and identical or comparable components are identified with the same reference numerals. In the Fig. In the embodiment shown in Figure 16, a first rotary element 126, connected to the retaining element 128, and a second rotary element 126' are provided, which are rotatable relative to each other. Furthermore, more than one transmission element 142 is provided. More precisely, two transmission elements 142 are provided. The transmission elements 142 are designed as Bowden cables, comprising a first and second Bowden cable core 146, 146'. The Bowden cable cores 146, 146' are each connected to the roller element 144, which is designed as a frame 112 or control tube, or as a clamp connected to the control tube. The Bowden cables also comprise a Bowden cable housing 148 in which both Bowden cable cores 146, 146' are movably guided. It is understood that a separate Bowden cable housing 148 can be provided for each Bowden cable core 146, 146'. The second rotary element 126' is rotatably arranged on or attached to a rotary element holder 150, which is rigidly connected to the vehicle with fork steering.The Bowden cable housing 148 is connected to the second pivot element 126' via the second receptacle 153 and to the control element 124 via the first receptacle 152, which is connected to the steering tube 116, for example, by means of a clamp 160 inside the steering tube 116. The Bowden cable cores 146, 146' are attached on opposite sides with respect to the pivot axis 139 and the steering axis 114, respectively. That is, the Bowden cables 146, 146' are attached on both sides of the pivot axis 139 and the steering axis 114, respectively, run diagonally, and are connected to the roller element at the attachment points 162, 162' and to the pivot element at the attachment points 163, 163'. The Bowden cable housing 148 is not axially stretchable. The rotary element holder 150 has at least one first stop 164, e.g. in the form of a pin. The first rotary element 126 has at least one second stop 164'.In this embodiment, for example, two stops 164' are arranged to limit the movement of the first rotary element 126 up to a certain rotation of the rotary element 126 clockwise and counterclockwise, preferably <80°. With a transmission ratio of approximately i=2, the limit is reached at a steering angle of approximately α=40°. The second rotary element 126' is designed such that springs 176, for example coil springs, torsion springs, or twist springs, and / or an elastic cord 178, provided on both sides, are held in position by the restoring force. The springs 176 are arranged, for example, between a projection 180 on the rotary element holder 150, which extends section by section circumferentially around the axis of rotation 139, and a receptacle 182 on the second rotary element 126'. The expander cord 178 can be arranged between the control element 124 and the second rotary element 126' and can in particular be pre-tensioned.The second rotary element 126' deflects when a steering angle is reached at which the first and second stops touch. The first rotary element 126 does not deflect further at larger steering angles. Instead, the second rotary element 126' moves with increasing restoring forces, resulting in a transmission ratio that depends on the steering position and is smaller at larger steering angles than at smaller ones.

[0085] Optionally, as described in more detail below, the axis of rotation 139 can be inclined relative to the steering axis 114. In particular, the axis of rotation 139 is preferably inclined forward relative to the steering axis 114, i.e., in the direction of travel. The axis of rotation 139 can, in particular, be inclined forward with respect to the vertical, preferably at an angle of 15° to 40° with respect to the vertical.

[0086] Fig. Figure 17 shows a further embodiment of a holder 118, a vehicle system 122, and a vehicle 110 with fork steering in a perspective view. In this embodiment, the functional element is designed as a lamp or bicycle headlight. The differences from the previous embodiments are described in particular, and identical or comparable components are provided with the same reference numerals. In the Fig. In the embodiment shown in 17, a pivot axis 139 is inclined relative to the steering axis 114 or to a vertical, i.e. a direction perpendicular to a horizontal defined by the ground on which the vehicle stands or moves.

[0087] The control element 124 is shown in particular. The steering axis 114 is inclined backwards relative to a vertical. The pivot axis 139 is inclined forwards relative to the steering axis 114 and the vertical. A light beam 184 emitted by the functional element in the form of a lamp is also shown as an example. The light beam 184 is inclined downwards relative to a horizontal, for example by 5°. A projection 186 of the rotating element 126, which in this embodiment is designed as a circular bevel gear, into a plane perpendicular to the steering axis 114 is also indicated. As can be seen, the projection 186 of the rotating element 126 into a plane perpendicular to the steering axis 114 forms an ellipse. Therefore, the distance between the contact points of a rolling element 144 designed as a bevel gear has radii that depend on the steering angle in this projection 186.The contact points 188 of the rotary element 126 and the contact points 188' of the rolling element can be described based on the mean diameters of the bevel gears. Particularly advantageous are embodiments in which contact points of the functional element-holding rotary element 126 with a rolling element 144 and / or with a transmission element 142 and / or with the control element 124, or contact points of the control element 124 with a rolling element 144 and / or with a rotary element 126 and / or with a transmission element 142, describe a steering-angle-dependent radius when projected onto a plane perpendicular to a steering axis of the steering tube and / or to its own axis of rotation.

[0088] Fig. Figure 18 shows, for an exemplary embodiment in which the rotary element 126 holding the functional element is directly or indirectly connected to the steering tube 116, the curves of the illuminance range as a function of the illuminance angle at various inclinations of the axis of rotation 139 of the rotary element 126 relative to the vertical. In this case, the illuminance range corresponds to the functional range of the functional element. The illuminance range is plotted on the Y-axis in meters. The orientation angle β of the functional element is plotted on the X-axis in degrees. The curve labeled "000" in the family of curves describes the curve of the illuminance range with a gear ratio of 0 between the rotational movement of the rotary element 126 and the rotational movement of the steering tube 116, which corresponds to a gear ratio of approximately 1, and an inclination of the steering axis 114 of 20° rearward relative to the vertical.For the subsequent curves, which are designated by their inclination angle of the axis of rotation 139 of the rotating element 126 relative to the vertical, a translation of the rotational movement of the rotating element 126 and the rotational movement of the steering tube 116 of 1 was chosen, which corresponds to a translation ratio of approximately 2. For example, curve 40 denotes a course of the headlight range as a function of the angle β for an inclination of the axis of rotation 139 of the rotating element 126 relative to the vertical of 40°. For explanatory purposes, it should be mentioned that it is assumed that the vehicle does not lean inwards when cornering, since the inward lean is a consequence of centrifugal force and thus dependent on the vehicle speed. The curves shown in... Fig. The 18 curves shown illustrate the case of the limit value for a driving speed of 0 km / h. At higher speeds, the wheel is tilted into the curve, which further reduces the beam range. The beam range when driving straight ahead is designed for approximately 10 m. An angle of approximately 15° to 40° or 60° to 80° forward from the vertical appears optimal. If the forward tilt is too shallow, the effect of the beam range reduction is minimal; with increasing tilt, the beam range increases upwards at large steering angles, which could dazzle oncoming traffic.

[0089] It should be noted that when the vertical is parallel to the steering axis 114 and the pivot axis 139, a constant transmission ratio i = β / α, which results from the quotient of the orientation angle of the functional element β and the steering angle α, is identical to the transmission ratio of the rotational movement of the functional element-holding rotary element 126 and the rotational movement of the steering tube 116. When the steering axis 114 and / or pivot axis 139 is inclined relative to the vertical, i can deviate from the transmission ratio of the rotational movement of the rotary element 126 and the rotational movement of the steering tube 116. In particular, when the steering axis 114 is inclined backwards, the orientation angle of the functional element β is reduced. This is clearly illustrated by curve 000. Although the points represent different steering angles in the range of α=0° to 75°, the maximum orientation angle of the functional element β is less than 75°. The endpoints of the curves in Fig.Figures 18 each show the angle β at a steering angle of α = 75°. The curves illustrate that the transmission ratio i decreases with increasing tilt angle of the axis of rotation 139 relative to the vertical.

[0090] It is explicitly emphasized that in each of the embodiments described herein, the axis of rotation 139 of the rotary element 126 can be inclined forwards or in the direction of travel relative to the steering axis 114 and / or a vertical. The inclination of the axis of rotation 139 of the rotary element 126 can be combined with a feature for changing the transmission ratio or provided separately.

[0091] The embodiments described above can be modified as follows. The Bowden cable cores can be designed as electrical leads, particularly when two Bowden cables 148, 148' are provided, allowing for fixed cable routing. Alternatively, sliding contacts for the electrical leads are also possible in the rotating element 126. The headlight and the mounting element can be tilted independently of each other. If the pivot axis 139 of the rotating element 126 is designed as a threaded rod with a large thread pitch, the inclination of the pivot axis 139 of the rotating element 126 can be changed depending on the steering angle, since the rotating element 126 then screws itself up or down along the pivot axis 139 as the steering is turned. Several pulley elements can also be used, such as a cable around the frame 112, then transmission to a hydraulic element, and from the hydraulic element back to a cable.The rotatable mounting of a rotating element or other elements can be achieved, for example, with a ball bearing or a sliding bearing.
