Description

[Technical field]

[0001] The present invention relates to a device for adjusting a viewing means assembly such as a mirror or camera arrangement for a motor vehicle, comprising a base part, an installation frame and a support frame, the base part being specifically designed for mounting to the body of the motor vehicle and the installation frame being designed for mounting a viewing means such as a mirror or a camera.

[0002] Such devices are known from the prior art, for example in the form of exterior mirrors for motor vehicles. The devices make it possible to adjust the viewing means assembly to the requirements of the motor vehicle operator, usually by electrical means. For example, the devices make it possible to pivot the viewing means assembly about multiple axes, for example in an upward and downward direction, but also horizontally, in order to adapt the field of view to the requirements of the vehicle operator. In addition to adapting the field of view, it is also usually possible to position the viewing means between a parked or reversed position and an extended position for operating the motor vehicle.

[0003] The structure of such devices comprises several components, many of which are force-coupled to each other to allow pivoting. In addition, protection devices are usually provided to allow the viewing means assembly to move when an external force acts on the viewing means assembly, for example to prevent damage to the viewing means assembly. In addition to an actuator, often electrically driven, an overload clutch, such as a slip clutch or similar safety device is also provided in this case.

[0004] A disadvantage of the known devices is in particular their highly complex and multi-component construction, which entails high costs in terms of part production and part storage, but also in the assembly of the respective device.

[0005] It is therefore an object of the present invention to provide a more cost effective, more durable and less complex device.

[0006] This object is achieved according to the independent claims by a device for adjusting a viewing means assembly, a viewing means device and a vehicle respectively provided with such a device.

[0007] In particular, the object is a device for adjusting a viewing means assembly, such as a mirror or camera arrangement, for a motor vehicle, comprising a base part, an installation frame and a support frame, the base part being in particular designed for attachment to the body of the motor vehicle, the installation frame being designed for the mounting of a viewing means, such as a mirror or a camera, the support frame being arranged on the base part by means of a first joint assembly such that it can rotate relative to the base part only about a first joint axis A1 extending substantially in an upward direction, i.e. between a retracted position, in which the support frame is for example aligned substantially along the body of the motor vehicle, and an extended position, in which the support frame is for example aligned substantially transversely to the body, the installation frame being arranged on the support frame by means of a second joint assembly such that it can pivot relative to the support frame only about a second joint axis A2 extending substantially transversely to the first joint axis A1, the first joint assembly being arranged on the support frame by means of a joint head on the base part and a joint head bearing assembly having a joint socket on a support frame, the joint head being received by the joint socket; a second joint assembly comprising a cradle bearing assembly, at least one bearing means arranged on the mounting frame and at least one complementary counter-bearing means arranged on the support frame, the bearing means and the counter-bearing means being slidably guided relative to one another such that the mounting frame can only pivot relative to the support frame about the second joint axis A2; the mounting frame having an intermediate socket arranged between the joint socket and the joint head, the intermediate socket being rotationally fixed relative to the joint socket about the first joint axis A1 by the bearing means and being rotatable relative to the joint head together with the joint socket about the first joint axis A1; at least one sliding ring is optionally arranged between the joint head and the intermediate socket, which sliding ring isThis is achieved by a device which forms a plain bearing between the joint head and the intermediate socket, by means of which the installation frame can slidably rotate relative to the base part about the first joint axis A1 and about the second joint axis A2.

[0008] Additionally, this object is achieved by a visibility means assembly and by a vehicle carrying such a respective device.

[0009] It should be noted that within the scope of the present invention, with regard to the above-mentioned first joint assembly and joint head bearing assembly, the joint head can also be arranged on the support frame and the joint socket can also be arranged on the base part. For ease of understanding and consistency of this specification, the joint head is also understood to optionally refer to the joint socket, if the joint socket on the support frame is accordingly understood to be the joint head. All embodiments described in this specification can be converted to such a structure in the same way, in which case the aforementioned substitution of joint socket and joint head must be made.

[0010] Within the scope of the present invention, the term "visualizing means" includes, inter alia, a mirror or a camera, as mentioned above. However, visualizing means may also be understood to mean other configurations and components that serve to better control a motor vehicle or similar vehicle. This includes, for example, lidar or IR sensors, blind spot indicators, heating devices, etc., which may be operatively connected to such a visualizing means assembly.

[0011] The term "joint head bearing" is optionally understood to mean a bearing received by a joint socket such that the joint head is movable, and in particular rotatable, within the joint socket, with the interposition of an intermediate socket, about at least one axis, and here about the first joint axis A1.

[0012] Within the scope of the present invention, a cradle bearing assembly is optionally understood to mean that only relative movement between the support frame and the installation frame about the second joint axis is possible. Optionally, a plain bearing assembly is provided herein in which the bearing means on the installation frame are slidingly guided by counter-bearing means on the support frame. A particular embodiment of this cradle bearing assembly is considered in more detail below.

[0013] Within the scope of the present invention, an upward direction is optionally understood to mean a vertical direction. The upward direction is optionally selected in relation to the required orientation of the viewing means assembly, in particular the viewing means. The vertical direction can be the direction of gravity, in particular if the vehicle on which the device is placed is aligned horizontally.

[0014] Within the scope of the present invention, a socket is understood to mean an optionally concavely shaped component, the inner wall of which forms the concave wall part, the outer wall of which forms the opposite wall part and, optionally, any resulting convex wall part that may be present.

[0015] It is conceivable that at least one viewing means is substantially rigidly mounted to the mounting frame, in particular that all viewing means are substantially rigidly mounted. The combination of the support frame, the mounting frame and the base part, and the corresponding bearing design, allows the viewing means to pivot together with the mounting frame about the first and second joint axes, while only reducing the number of joint components required for this purpose. The base part forms a central component that houses both the support frame and the mounting frame, the mounting frame being mounted on the support frame and pivotable about an axis relative to the support frame.

[0016] When the viewing means is arranged on the installation frame, the pivoting movement of the viewing means about the second joint axis, in particular in the upward and downward direction, can be performed, for example, via the installation frame, while the pivoting movement, for example in the inward and outward direction, can be performed about the first joint axis by rotating the support frame together with the installation frame about the first axis. Thus, the viewing means can be pivoted, for example, between a retracted position and an extended position. It is also possible to correct the viewing angle of the viewing means on the installation frame, for example, towards or away from the vehicle body, using this arrangement. This correction of the viewing means or the pivoting of the viewing means about the first joint axis can be performed independently of the folding and unfolding between the retracted and extended positions. Optionally, the device combines both the movement of the viewing means, for example, between the operating position and the parking position, and the adjustment to provide the driver with an optimal viewing angle.

[0017] Optionally, the main extension axis of the base part extends coaxially with the first joint axis. Optionally, the main extension axis, in particular the rotation axis, of the joint head and / or the intermediate socket extends coaxially with this first joint axis. The same optionally applies to the sliding ring, in which case it is possible in particular for the centre of the circle to be located on the first joint axis. Optionally, the joint head and the base part can be detachably connected to each other. However, an integrated design is also possible. Optionally, the joint head can be pressed into the base part in the form of a slip-on cap, and as mentioned, this also applies when the joint head is embodied as a joint socket.

[0018] Optionally, the inner wall of the intermediate cup and the outer wall of the joint head are spaced apart from each other to form a relative movement gap, and the sliding ring is mounted in this relative movement gap between the intermediate cup and the joint head under bearing pressure. The relative movement gap is optionally designed to extend between the joint head and the intermediate socket such that there is no direct contact between them during any and all relative deflections between them. The sliding ring is optionally designed to be able to transmit vertical forces from the installation frame to the base part, in particular coaxially with the first joint axis.

[0019] A corresponding relative movement gap may be formed between the inner side wall of the joint socket and the outer side wall of the intermediate joint socket, and the bearing means and counter-bearing means optionally ensure that this relative movement gap is maintained during pivotal movement of the installation frame relative to the support frame, in particular that there is no contact between the inner side wall of the joint socket and the outer side wall of the intermediate socket.

[0020] The arrangement of the sliding ring between the intermediate socket and the joint head allows the installation frame to be mounted so as to be rotatable relative to the base part (together with the support frame) around the first joint axis and (by itself) around the second joint axis. The coupling between the installation frame and the support frame ensures that the support frame can rotate relative to the base part around the first joint axis. The use of the sliding ring allows for a long-lasting joint head bearing assembly with very little wear. In particular, dirt located between the joint head and the intermediate socket can be easily removed through the relative movement gap. In addition, the design of the sliding ring ensures a constant range of movement between the installation frame and the base part, since the deformation of the sliding ring is very small. The adjustment of the rotational force required for the rotational or pivotal movement is also facilitated by the sliding ring, since the gap between the installation frame and the base part changes only slightly during the operation process.

[0021] Optionally, the sliding ring is arranged between the joint head and the intermediate socket so as to form a bearing, whereby the installation frame, in particular the intermediate socket, can pivot about the second axis relative to the base part or the joint head, in particular in a sliding manner. In this case, a plain bearing can also be formed between the intermediate socket, the sliding ring and the joint head. During the movement about the second joint axis, in particular in this case, the sliding ring optionally moves relative to the joint head and / or relative to the intermediate socket about the second joint axis. In particular, the sliding ring moves along the inner wall of the intermediate socket and / or along the outer wall of the joint head.

[0022] Optionally, the sliding ring is made of metal, ceramic, or glass. Optionally, the sliding ring has a Brinell hardness of 200-900 HB. The sliding ring designed in this way reduces wear of the bearing assembly. The design and arrangement of the sliding ring between the intermediate socket and the joint head allows for taking into account the shrinkage and / or expansion of the mounting frame, the base part, and the support frame, which are optionally manufactured as plastic components, without changing the basic characteristics of the device.

[0023] Optionally, the outer wall of the joint head and / or the inner wall of the intermediate socket have, at least in some parts, a geometric shape that is rotationally symmetric around the first joint axis, in particular a geometric shape that is spherical, at least in some parts. It is conceivable that the joint head or the outer wall of the joint head on the outer wall side and the intermediate socket or the inner wall of the intermediate socket on the inner wall side are embodied as geometric bodies or surfaces that are complementary to each other. In particular, both can be embodied as spherical bodies. However, it is also conceivable to form different geometries relative to each other. For example, the joint head can be embodied as a spherical body at least in some parts and the intermediate socket can be embodied as a different solid body at least in some parts. For example, the intermediate socket can have the geometry of a conical disk in some parts. The same applies to the inverse construction of the joint head.

[0024] It is also conceivable to arrange channels in the intermediate socket, in particular in the inner wall of the intermediate socket and / or in the joint head or in the outer wall of the joint head, which improve the removal of contaminants, in particular particles, in the relative movement gap. Such a channel may for example extend vertically with its main extension axis, in particular downwards in the direction of the first joint axis. Optionally, it is also conceivable to form corresponding recesses, ridges, depressions or gaps on the sliding ring, which allow the removal of dirt in the relative movement gap. These may be aligned with such channels in order to allow an improved removal of contaminants, in particular particles.

[0025] Optionally, the intermediate socket has a feedthrough through which the base part, in particular the shaft of the base part, can be guided to the support frame, optionally from the outside to the inside of the support frame. Optionally, it is conceivable that the shaft can be guided through the intermediate socket feedthrough, so that the intermediate socket completely surrounds the shaft. The feedthrough can be designed to be complementary to the shaft, such that the edges of the feedthrough (which can include edges facing the feedthrough that define the boundaries of the feedthrough) do not contact the shaft in certain parts. Optionally, at least in some sections, there is no binding force between the shaft and the feedthrough. It is conceivable that the duct or the edges of the duct act as pivot stops in some areas. This applies in particular when the installation frame is pivoted about the second joint axis, as will be explained in detail below. At least a part of the base part, in particular the shaft, can rest against such a pivot stop in a manner that prevents pivoting.

[0026] Optionally, the feedthrough length DL of the feedthrough, which extends in the circumferential direction U2 around the second joint axis on the outer wall of the intermediate socket, is designed such that a pivot gap in this circumferential direction U2 is formed between the base part, in particular the shaft of the base part, and the intermediate socket, which allows a movement of the intermediate socket relative to the shaft, in particular a pivot movement around the second joint socket. Optionally, the feedthrough is embodied as a slot extending in the direction of the pivot movement axis A3. The pivot movement axis A3 optionally extends transversely to the first joint axis A1 and the second joint axis A2. This describes in particular the direction of movement that the edge of the feedthrough follows when the installation frame pivots about the second joint axis relative to the base part.

[0027] According to the above paragraphs, an optional feed-through is provided, embodied as a free space in the intermediate socket, allowing the base part to be guided through the intermediate socket. This feed-through optionally allows the insertion of a base part having a receiving part formed thereon. The receiving part can be formed on the joint head. As will be explained later, this receiving part can be used, for example, to form a slip or similar clutch. Such a receiving part also optionally allows the placement of a fixing means, for example, pressing the intermediate socket between the joint head and the base part while pressing the support frame in the direction of them. Optionally, fixing means in the form of a pre-tensioning means, for example a compression spring, are provided, which press the joint socket and / or the intermediate socket against the joint head, thus resulting in a constant bearing pressure between the intermediate socket, the sliding ring and the joint head.

[0028] Such fastening means can be force-coupled to the base part, in particular to the receiving part described above.

[0029] The feedthrough is optionally designed to allow the installation frame to be pivoted in two opposite directions about the second joint axis. This allows, for example, a viewing means attached to the installation frame to be pivoted up and down. As already mentioned, the end regions of the feedthrough, in particular the edges, in particular the end regions of the feedthrough embodied as elongated holes, can serve as stop means preventing further pivoting of the installation frame relative to the base part. Optionally, stop means specially designed for this function can be provided on the intermediate socket and / or counter stop means can be provided on the base part. Optionally, stop means such as protrusions, but also damping means can be provided in some parts, in particular on the edges of the feedthrough. It is conceivable that the length of the feedthrough, in particular the length of the elongated holes, defines the maximum pivot angle about the second joint axis. The longer the slot, the larger the optional pivot angle.

[0030] Optionally, the intermediate socket has in its inner wall an upper bearing groove, optionally concentric with the first joint axis, in which the sliding ring is mounted and optionally fixed against movement relative to the intermediate socket in the upward direction, or the joint head has in its outer wall a lower bearing groove, optionally concentric with the first joint axis, in which the sliding ring is mounted and optionally fixed against movement relative to the joint head in the downward direction. It is conceivable that the sliding ring is mounted on the inner wall of the intermediate wall and / or on the outer wall of the joint head so as to be fixed with respect to one of these components, i.e. the intermediate socket or the joint head, and to move together therewith during rotation about the first joint axis. It is also conceivable that the joint head can be designed to be freely supported such that when the mounting frame is pivoted relative to the base part or when the intermediate socket is pivoted relative to the joint head, the joint head is free to move about a first joint axis relative to both components and / or when the mounting frame is pivoted relative to the base part, the joint head is free to move about a second joint axis. In particular, in this section, the definitions of upward and downward movement optionally refer to the directions in the neutral position of the device, i.e. when the mounting frame is not pivoted relative to the base part about the second joint axis.

[0031] It is conceivable to provide an upper bearing groove in the intermediate socket, so that the sliding ring can be mounted therein to move with the mounting frame during pivotal movement of the mounting frame relative to the base part about the second axis, and optionally not to move in a pivotal manner relative to the base part. It is conceivable to provide a lower bearing groove in the joint head, so that the sliding ring can be mounted therein to move with the joint head during pivotal movement of the mounting frame relative to the base part about the second axis, and optionally not to move in a pivotal manner relative to the base part.

[0032] It is conceivable that the bearing groove is designed to allow force transmission from the installation frame to the base part, in particular the joint head, and thus to allow vertical forces to be transmitted from top to bottom. It is conceivable that the bearing groove is designed to prevent a change in the circumference of the sliding ring, in particular as a result of this vertical force. In this way, inter alia, the freedom of movement mentioned above is maintained and it is ensured that, at least in some parts, the inner wall of the intermediate socket and the outer wall of the joint head do not come into contact with each other. The bearing groove can be used to fix the position of the sliding ring so that it is not wedged against the intermediate socket and / or the joint head. The bearing groove can extend concentrically with the first joint axis.

[0033] It is basically conceivable to form a plurality of sliding rings or a plurality of bearing grooves, where each bearing groove is optionally designed to be complementary to a sliding ring. The bearing groove, when viewed in cross section, can have a geometry in which the sliding ring is at least partially received over its entire surface and is under bearing pressure together with said bearing groove. It is also possible for the bearing groove, when viewed in cross section, to be designed such that it only contacts the sliding ring at certain points. For example, when viewed in cross section, the sliding ring can have a circular or similarly rounded outer wall and the bearing groove can have a straight inner wall, so that a point bearing is created between the bearing groove and the sliding ring, and optionally a linear bearing is created, in particular in some parts in the circumferential direction. When viewed over the circumference of the sliding ring or bearing groove, a linear bearing preferably occurs between the sliding ring and the bearing groove, in particular in some parts. This also applies, optionally, to bearing designs without bearing grooves, i.e. between the intermediate socket and the sliding ring and / or the joint head and the sliding ring. Here too, a linear bearing can optionally be present at least in some parts. This is particularly true when, as mentioned above, there are exhaust channels between the sliding ring and the intermediate socket or between the sliding ring and the joint head which serve to exhaust contaminants in the relative movement gap.

[0034] Optionally, the sliding ring has fixing means and the intermediate socket or the joint head has counter fixing means or vice versa, which engage with each other such that the sliding ring is fixed against rotation about the first joint axis A1 relative to the intermediate socket or the joint head, and optionally the fixing means has at least one protrusion protruding from the rotation axis A4, optionally from the sliding ring plane of the sliding ring, and the counter fixing means has at least one complementary protrusion receiver. This can also be true vice versa.

[0035] Optionally, the counter fixing means or fixing means can be formed in the upper bearing groove on the intermediate socket or in the lower bearing groove of the joint head.

[0036] The sliding ring can be fixed, for example, to the inner wall of the intermediate wall, such that when the base part is moved relative to the installation frame about the first joint axis and / or the second joint axis, the sliding ring moves together with the intermediate socket relative to the base part. The same applies to the arrangement of the sliding ring on the base part or on the joint head. The fastening means can, for example, have at least one protrusion on the sliding ring, which can be coupled to a protrusion receiver as a counter fastening means. The counter fastening means can also have at least one protrusion, which can be coupled to a corresponding protrusion receiver as a fastening means.

[0037] Optionally, the sliding ring is embodied as an open sliding ring, in which case at least one free end region of the sliding ring is embodied as a fixing means, which can optionally be embodied as a protrusion and optionally as a protrusion angled from its rotation axis A4, optionally from the sliding ring plane of the sliding ring.

[0038] Optionally, at least one free end region of the sliding ring is conceivably rounded, which prevents damage to the sliding ring surfaces, for example the inner wall of the intermediate socket and / or the outer wall of the joint head.

[0039] Optionally, the second joint axis A2 and the first joint axis A1 intersect.

[0040] Optionally, the cradle bearing assembly is designed such that at least one bearing means of the installation frame and at least one counter-bearing means of the support frame form at least one strip bearing. Optionally, the bearing means is embodied as at least one, in particular arc-shaped, convex bearing arch and / or the counter-bearing means is embodied as at least one, in particular arc-shaped, concave bearing arch or has one of such. A plurality of such bearing arches can be used. The bearing means and the counter-bearing means are preferably designed such that they form a plain bearing, the bearing means being optionally able to slide along the counter-bearing means. It is conceivable that the bearing means is embodied as a bearing strip over its entire length. The same optionally applies to the counter-bearing means. It is conceivable to design the bearing means in the form of a plurality of bearing strips, which are arranged side by side and / or one behind the other in a row and can slide along the counter-bearing means embodied as a strip bearing counter-bearing means. This also applies vice versa. Here, for example, one or more support legs are provided as bearing means which seat on corresponding bearing strips as counter-bearing means and allow for plain bearing. It is conceivable to provide a suitable coating, lubricant or similar device between the bearing means and the counter-bearing means to improve the bearing sliding.

[0041] Within the scope of the present invention, a strip bearing is understood to mean a bearing having a strip-shaped bearing extension. According to the present invention, forces are introduced into such a strip bearing as distributed loads or, in the case of a minimum designed bearing width, as linear loads, which extend to a greater extent in the main direction of extension corresponding to the main direction of extension of the strip bearing than transversely thereto.

[0042] It is envisaged that the bearing means and counter-bearing means may be integrally formed with the mounting or support frame, for example the mounting frame and / or the support frame may be manufactured as a cast component and the bearing means or counter-bearing means cast integrally therewith.

[0043] The strip bearing is optionally embodied as a bearing having the smallest possible bearing width in relation to the bearing length. The strip bearing preferably has a bearing width including 10% of the bearing length, optionally at least less than 8% and optionally less than 5%. Optionally, the strip bearing is designed to form a linear bearing. The bearing length is the length of the bearing in the direction of relative movement of the bearing means and the counter-bearing means. The bearing width extends transversely thereto.

[0044] Optionally, at least one bearing means is formed on an outer wall of the intermediate socket and at least one counter-bearing means is formed on an inner wall of the joint socket. Within the scope of the invention, the inner wall of the joint socket optionally forms a bearing surface of the joint socket and is a wall facing the joint head. The outer wall of the intermediate socket optionally forms the intermediate socket on the outside and is a wall facing the joint socket. The outer wall of the joint head optionally forms the outside of the joint head and is a wall facing the intermediate socket.

[0045] Optionally, the bearing means and the counter-bearing means are arranged in an area where the joint head bearing is also formed. Optionally, a plurality of bearing means and counter-bearing means are formed diametrically with respect to each other with respect to the first joint axis. Optionally, the bearing means is embodied as a sector of a rotating body, the axis of rotation of which lies on the second joint axis. In such an embodiment, the bearing means is embodied, for example, as a bearing arch whose centre is on the second joint axis. The same applies to the counter-bearing means. The sectors of the rotating body of the bearing means and the counter-bearing means preferably have different radii. The bearing means and the counter-bearing means preferably have bearing surfaces that are at least partially complementary to each other.

[0046] As will be explained below, it is contemplated that bearing means and / or counter-bearing means are formed and operatively connected to corresponding actuators, in particular actuators that enable electrical or similar mechanically driven pivoting of the viewing means arrangement or form corresponding engagement means for these actuators.

[0047] Optionally, at least one bearing means and at least one counter-bearing means have lateral guide means, by which a fixing of the bearing means relative to the counter-bearing means in the direction of the second joint axis is provided. Such bearing means and counter-bearing means can then form, for example, a sliding guide which allows a pivoting movement about the second joint axis, but prevents any other movement, in particular in a direction deviating from this second joint axis, whereby, for example, a translational movement in the direction of the second joint axis can be blocked. Such a translational fixation can also be provided via a bearing seat of a sliding ring between the intermediate socket and the joint head. In particular, the fixation can be achieved by a geometrically complementary formation between the intermediate socket and the joint head.

[0048] In order to achieve the abovementioned fixation between the bearing means and the counter-bearing means, it is possible, for example, to provide the bearing means and / or the counter-bearing means with lateral guide means which slide relative to one another, in particular in the direction of the second joint axis. It is also conceivable to design the bearing means and the counter-bearing means in such a way that the fixation between the intermediate socket and the joint socket is ensured in the direction along the first joint axis, in particular against fixation away from one another. In such an embodiment, the bearing means can have an undercut relative to the counter-bearing means which generates this fixation. This is optionally also possible vice versa.

[0049] Optionally, at least one arc axis of at least one bearing means embodied as a convex bearing arch and / or at least one counter-bearing means embodied as a concave bearing base extends coaxially with the second joint axis. The arc axis is an axis about which the bearing arch or the counter-bearing arch extends with a certain radius. Concave and convex optionally refer to the arrangement of the bearing arches on the component. Both the bearing arch and the counter-bearing arch optionally extend around the same joint axis. The concave bearing arch optionally forms a bearing surface on its concave inner side and the convex bearing arch optionally forms a convex, in particular complementary, bearing surface on its outer side.

[0050] Optionally, the installation frame is fixed to the support frame against movement in the direction of the first joint axis via fixing means, in particular at least one fixing pin extending parallel to the second joint axis between the installation frame and the support frame and mounted on the support frame via an axial bearing means. The fixing is optionally performed in the direction of the first joint axis to prevent the installation frame and the support frame from moving away from each other. The arrangement of the fixing means and the axial bearing means can optionally be configured such that they form bearing means and counter-bearing means for the cradle bearing assembly. In such a case, in particular, the fixing means can optionally be embodied as a bearing pin, while the counter-bearing means can be embodied as at least one elongated hole, through which a pin can pass and move along the arc axis of the elongated hole, thus allowing a pivoting movement between the installation frame and the support frame.

[0051] Optionally, the device comprises a first actuation means, optionally electrical, with a drive gear force-coupled to an output gear on the base part, in particular on the shaft, optionally at least partially surrounding the shaft, so that the support frame can be rotated relative to the base part by the actuation means. Optionally, the actuation means transmits a force to the drive gear, which is then converted into a relative rotation between the base part and the support frame via a force coupling between the drive gear and the output gear. Optionally, it is also conceivable to provide a second actuation means, optionally electrical, with a drive gear force-coupled to the output gear on the installation frame, in particular to at least one bearing means of the installation frame, so that the installation frame can pivot relative to the support frame. It is also conceivable to provide the output gear on a counter-bearing means, if this is provided on the installation frame. The drive gear and the output gear can for example be embodied as a gear structure coupled to each other. For example, a gear wheel arch can be provided on a bearing means or counter-bearing means to which a counter gear wheel, in particular a worm gear wheel, is force-coupled. Optionally, a force coupling between the drive gear and the output gear is provided such that a pivot lock is formed when an external force is applied to the device that would otherwise cause the base part to pivot relative to the mounting or support frame and pivot relative to the mounting frame. Such a locking mechanism may include decoupling of the lock when a threshold force is exceeded. Such a structure may be, for example, a slip clutch or similar overload clutch.

[0052] Optionally, the first and second actuation means are both arranged on a support frame, in particular within an interior space of such support frame.

[0053] Optionally, the mounting frame at least partially surrounds the support frame, which is optionally arranged and mounted in the mounting frame in the form of a cradle. It is conceivable that the support frame within the mounting frame is substantially completely enclosed by the mounting frame and / or is substantially completely closed so as to form an interior space itself. Such a closed support frame provides a safe containment of often sensitive components, especially if the actuation means and also the drive gear and / or the output gear are arranged on the support frame. It is also conceivable to design the support frame as a module, so that it can be inserted in a fully assembled form into the mounting frame, especially together with the actuation means and corresponding gears installed. After the support frame is inserted into the mounting frame or after the cradle bearing assembly is formed between the support frame and the mounting frame, a viewing means cap can be optionally arranged on the mounting frame so that the support frame is optionally substantially completely enclosed. The viewing means cap optionally comprises a viewing means. The viewing means can also be arranged on the mounting frame. The viewing means optionally includes a viewing means cap, which in this case substantially completely surrounds the support frame. The design of the support frame, in particular as a carrier of the actuation means and gears, results in a construction in which the installation frame can be very slim. In particular, it is conceivable to mount only very thin components with reduced volume on the installation frame, such as mirrors, cameras or sensors.

[0054] Optionally, the drive gear and / or output gear form a rotational lock such that relative movement between the support frame and the base part is locked as a result of an externally applied torque on the support frame about the first joint axis, and a slip or similar overload clutch is optionally provided which releases the rotational lock when a specified overload torque acts on the support frame, for example as a result of an object or person colliding with a side end of the viewing means to which the support frame is force coupled. Such a structure may also be provided between the support frame and the mounting frame, for example when a specified overload torque acts on the viewing means on the mounting frame.

[0063] 1 to 4 show different illustrative views of a first embodiment of the device according to the invention. This device is also suitable for adjusting a viewing means assembly, such as a mirror arrangement or a camera arrangement for a motor vehicle. However, these arrangements are not shown in the illustrative views, since they are known from the prior art.

[0064] The device according to the invention comprises a base part 10, a mounting frame 30 and a support frame 50. As mentioned above, the base part 10 is especially designed for attachment to the body of a motor vehicle. Such attachment may be rigid so that the base part can act as a fixing point for the device, with particular reference to FIG.

[0065] The mounting frame 30 is designed to mount a viewing means, e.g. a mirror, a camera, but also corresponding sensor means or other components serving to improve visibility and safety, in particular when driving a vehicle. This viewing means can be attached in a substantially rigid manner to the mounting frame 30, so that the viewing means also move as soon as the mounting frame moves relative to the base part 10. According to the invention, no further adjustment devices (e.g. joint assemblies, actuator means, etc.) are optionally provided between the mounting frame and the viewing means in order to move the viewing means relative to the mounting frame.

[0066] The support frame 50 can be arranged on the base part 10 by a first joint assembly so that it can only rotate relative to the base part about a first joint axis A1. This first joint axis A1 extends substantially in an upward direction. The definition of the term "upward" has already been considered in the introduction. The support frame 10 can be rotated so that it can pivot, for example, between an extended position, for example a driving position, and a reversed position, for example a parking position. As will be explained below, the first joint assembly is embodied as a joint head bearing assembly, and since the support frame 10 can pivot about the first joint axis A1, this pivoting is also referred to as rotation, and the support frame 50 rotates relative to the base part 10 about the first joint axis A1. Optionally, the parts of this joint assembly are arranged with their joint surfaces concentrically around the first joint axis A1.

[0067] As explained in the introduction, the extended position may also be defined, for example, as a position in which the support frame 50 is oriented substantially transversely relative to the body. The retracted position may be defined, for example, as the support frame is substantially aligned along the body of the vehicle. As explained below, the support frame is coupled to the mounting frame in such a manner that it can rotate together with the mounting frame about a first axis of rotation.

[0068] The mounting frame 30 is arranged on the support frame 50 by means of a second joint assembly such that, for its parts, it can only pivot relative to the support frame 50 about a second joint axis A2. As shown in particular in FIG. 1, this second joint axis extends transversely to the first joint axis.

[0069] As can be seen in particular in Figures 1 and 3, the arrangement between the support frame and the installation frame by the cradle bearing assembly optionally results in a cradle structure, the support frame being arranged in the installation frame in the form of a cradle. In the embodiment shown in Figure 1, only the lower part of the installation frame 30 is shown. It is conceivable that the installation frame 30 is formed by a cap, in particular as a viewing means cap, so as to completely surround the support frame. The viewing means can also be embodied as such a cap or have such a cap. Thus, in a thus designed installation frame 30, pivoting of the support frame relative to the installation frame is possible.

[0070] The support frame 50 itself can also be embodied as a closed or partially closed component (see FIG. 1). Optionally, the support frame houses on its inside 57 (see FIG. 3) actuation means such as a motor, in particular an electric drive motor, which allows pivoting of the support frame 50 relative to the installation frame 30 and the base part 10. In addition to these actuation means, which are not shown in the figures for simplicity, a corresponding drive gear can be provided in the support frame, which is force-coupled to the actuation means. The drive gear can then in turn be coupled to a corresponding output gear (see for example FIG. 4, reference number 11 or FIG. 3, reference number 31), thus allowing corresponding rotational and pivoting movements. An output gear can also be arranged in the support frame.

[0071] The first joint assembly comprises a joint head bearing assembly with a joint head 12 on the base part 10 and a joint socket 51 on the support frame 50, the joint head 12 being received by the joint socket 51. As already explained in the introduction, it is also possible to design the device in a correspondingly inverted manner, in which case the joint head is formed on the support frame 50 and the joint socket is formed on the base part 10. All other components associated with this arrangement must then be adapted accordingly. This of course also applies to all the features mentioned in this specification with regard to these components and their arrangement relative to the base part and the support frame.

[0072] In this embodiment, the joint head 12 is detachably connected to the base part 10. The joint head is embodied as a plug-in head, which means that it is pressed onto the base part via the shaft 14 of the base part and optionally fixed around the first joint axis A1. The joint head 12 can also have a receiving means 13 for the output gear 11 and / or an additional coupling device, for example a slip clutch or a similar overload clutch 85. When a certain overload torque is applied to the support frame 50, but of course also to the installation frame 30 coupled to the support frame 50, and in particular to the viewing means arranged on the installation frame 30, this overload clutch can in particular release the force coupling between the drive gear and the output gear between the support frame and the base part, thereby allowing an emergency rotation. An example of such an emergency rotation is the folding of an exterior mirror when an external load causing an overload torque is applied. By way of example, the overload clutch 85 is here provided with a number of coupling rings 86, 88 which are force-coupled by a compression spring 87 and pressed against the base part 10 or the joint head 12 with the interposition of the support frame and the output gear 11. According to the invention, the parts of the overload clutch can also be arranged in the interior 57 of the support frame. For assembly, the support frame optionally has a cover 92 which is removably attached to the support frame 50. In this embodiment, the cover 92 can be designed to apply the preload required for the overload clutch 85 to the compression spring 87.

[0073] The joint head 12 and the joint socket 51 are optionally designed such that the joint socket 51 at least partially surrounds the joint head 12. Optionally, the joint socket 51 is designed to surround the joint head 12 at most substantially in a half-shell shape, so that in the absence of any fixing means the joint head 12 can be inserted into the joint socket 51, in particular in the direction of the first joint axis A1.

[0074] As shown in figures 1 and 2, the installation frame 30 has an intermediate socket 36 which is arranged between the joint socket 51 and the joint head 12. This intermediate socket 36 is designed to be received by the joint socket 51 as well. The intermediate socket is also designed to accommodate the joint head. Here too the definitions given above of the joint socket and joint head or the formation of the joint socket and joint head are applicable in order to allow mutual insertion and reception.

[0075] As shown particularly in FIG. 2, the joint socket, intermediate socket, and joint head form a layered construction with an outer layer, or joint socket, and an innermost layer, or joint head, surrounding the joint socket therebetween.

[0076] As also shown, in addition to the first joint assembly embodied as a joint head bearing assembly, a second joint assembly is provided in the form of a cradle bearing assembly. It comprises at least one bearing means 32 arranged on the mounting frame and at least one complementary counter-bearing means 52 arranged on the support frame 50. These are slidingly guided relative to each other such that the mounting frame 30 can only pivot about the second joint axis A2 relative to the support frame 50 via these bearing means and counter-bearing means. Optionally, the bearing means and counter-bearing means of the cradle bearing assembly form a plain bearing.

[0077] According to the invention, the intermediate socket 36 is rotatably fixed relative to the joint socket 51 about the first joint axis A1 by means of bearing means 32 and / or counter-bearing means 52. In particular, the intermediate socket can be rotated together with the joint socket 51 only about the first joint axis A1, i.e. relative to the joint head 12, when the support frame 50 performs a rotation relative to the base part 10, for example via electrical actuation means. The cradle bearing assembly allows the installation frame to pivot relative to the support frame.

[0078] When the viewing means is arranged on the installation frame 30, the pivoting movement of the viewing means about the second joint axis, in particular in the upward and downward direction, can be performed, for example, via the installation frame, while the pivoting movement, for example in the inward and outward direction, can be performed about the first joint axis by rotating the support frame together with the installation frame. The viewing means can thus be pivoted, for example, between a retracted position and an extended position. However, it is also possible to correct the viewing angle of the viewing means on the installation frame, for example, towards or away from the vehicle body, using this configuration. This correction of the viewing means or the pivoting of the viewing means about the first joint axis can be performed independently of the folding and unfolding between the retracted and extended positions. Optionally, the device combines both the movement of the viewing means, for example, between the operating position and the parking position, and the adjustment to provide the driver with an optimal viewing angle.

[0079] As can be seen especially in Figures 1-3, at least one sliding ring 70 is arranged between the joint head 12 and the intermediate socket 36, forming a plain bearing between the joint head 12 and the intermediate socket 36, by which the installation frame 30 can slidably rotate relative to the base part 10 about the first joint axis A1. Optionally, the intermediate socket 36 and the joint head 12 form a press fit via the sliding ring 70, and a bearing force is transferred via the sliding ring 70 from the installation frame 30 or the support frame 50 to the joint head 12 or the base part 10, especially in the direction of the first joint axis A1.

[0080] Optionally, a sliding ring 70 is arranged between the joint head 12 and the intermediate socket 36 so as to form a sliding bearing, whereby the installation frame 30, in particular the intermediate socket, can pivot about a second axis relative to the base part 10 or the joint head, in particular in a sliding manner. In this case, a plain bearing can also be formed between the intermediate socket, the sliding ring and the joint head. During the movement about the second joint axis, in this particular case, the sliding ring optionally moves relative to the joint head and / or relative to the intermediate socket about the second joint axis. In particular, the sliding ring moves along the inner wall of the intermediate socket and / or along the outer wall of the joint head.

[0081] Optionally, as mentioned, when the mounting frame 30 pivots about the second joint axis A2, the sliding ring also moves in a pivotal movement about the second joint axis relative to the intermediate socket 36 and / or the joint head 12. This relative movement optionally depends on whether the sliding ring 70 is fixed to the intermediate socket or the joint head 12, as described in more detail below.

[0082] It should be noted that the pivot angle of the support frame relative to the base frame can optionally be greater than the pivot angle between the support frame and the mounting frame. The device is optionally designed to produce a rotation angle about a first rotation axis between the support frame 50 and the base part 10 that is at least 60 percent, optionally at least 70 percent, and optionally at least 80 percent greater than the pivot angle of the mounting frame 30 relative to the support frame 50. This of course also applies to the pivot angle of the mounting frame 30 relative to the base part 10 about the second joint axis, since the mounting frame 30 is cradled to the support frame 50.

[0083] Optionally, the sliding ring 70 is arranged concentrically with the first joint axis A1. Optionally, the joint head 12 is arranged concentrically with the first joint axis A1, and optionally the intermediate socket and / or the joint socket are concentric with the first joint axis A1.

[0084] Figures 5 to 11 show another embodiment which is similar to the embodiment according to Figures 1 to 4, and which is similar and in particular identical in different views and details. For the sake of brevity, and optionally with regard to the basic configuration of this embodiment, reference is made to the preceding paragraphs relating to the previously described embodiment.

[0085] In particular, in figure 5 it can be seen that the inner wall 38 of the intermediate socket 36 and the outer wall 19 of the joint head 12 are spaced apart from each other so as to form a relative movement gap 20. A sliding ring 70 is mounted in this relative movement gap 20 between the intermediate socket 36 and the joint head 12 under bearing pressure, forming a plain bearing between the inner wall of the intermediate socket, the outer wall of the joint head and the sliding ring. In this particular context, the sliding ring is optionally made of metal, ceramic or glass, optionally having a Brinell hardness of 200 to 900 HB. This results in a minimum of wear on the sliding ring, which for construction reasons has to bear very high loads.

[0086] A corresponding relative movement gap 40 (see FIG. 6 ) may be formed between the inner wall 58 of the joint socket 51 and the outer wall 35 of the intermediate socket 36. The bearing means 32 and the counter-bearing means 52 optionally ensure that this relative movement gap 40 is maintained during pivotal movement of the installation frame relative to the support frame. Optionally, the joint socket 51 and the intermediate socket 36 contact each other exclusively via correspondingly arranged bearing means 32 and / or counter-bearing means 52. The same applies to the intermediate socket 36 and the joint head 12, which optionally contact each other exclusively via a sliding ring 70.

[0087] The mentioned relative movement spaces 20, 40 ensure a reproducible sliding resistance between the components that can pivot relative to each other and, in addition, optionally allow the removal of contaminants that accumulate between the respective components. It is also conceivable to place suitable sliding aids, such as greases and oils, but also coatings on and between the bearing means, counter-bearing means and sliding rings, which improve the sliding support of the components relative to each other.

[0088] As can be seen in particular in figures 5 and 6, the outer wall 19 of the joint head 12 and / or the inner wall 38 of the intermediate socket 36 have, at least in some parts, a geometry that is rotationally symmetric about the first joint axis A1, in particular a geometry that is spherical in at least some parts. In the embodiment shown here, the respective components, i.e. joint head 12 and intermediate socket 36, have a spherical geometry with a common spherical centre. The joint head 12 and intermediate socket 36 differ in their radii. The same applies to the joint socket 51, which also has, in some parts, a corresponding rotationally symmetric geometry, in this embodiment optionally a spherical geometry in some parts. The respective geometries of the joint head, the intermediate socket and the joint socket are at least partially complementary to one another, allowing a sandwich arrangement of the respective components relative to one another. It is conceivable to design at least one component as a part-spherical component and to design the corresponding assigned component with a different geometry. For example, the intermediate socket can have the geometry of a conical disk, inside of which the joint head 12 fits with the interposition of a sliding ring 70. Such an arrangement can also exist between the joint socket 51 and the intermediate joint socket 36. It is also conceivable to design in particular the geometry of the intermediate socket, at least in some parts, such that the inner wall 38 of the intermediate socket follows a different geometry than the outer wall 35. For example, a spherical geometry can be provided on the inside, at least in some parts, while a different geometry is formed on the outside, or vice versa.

[0089] As can be seen in particular in Figures 8 to 10 in detail, the intermediate socket 36 optionally has a feedthrough 39 through which the base part, in particular the shaft 14 of the base part, can be guided into the support frame 50, optionally from the outside 56 to the inside 57 of the support frame 50 (see Figure 3). This feedthrough 39 optionally has a feedthrough length DL (see Figure 1) extending in a circumferential direction U2 around the second joint axis A2 along the wall of the intermediate socket. The feedthrough is designed in this circumferential direction U2 such that a pivot gap 15 is formed between the base part 10, in particular the shaft 14, and the intermediate socket 36, which allows a movement of the intermediate socket 36 relative to the base part 10 or the shaft 14, in particular a pivot movement about the second joint axis A2 (see also Figure 1).

[0090] As shown in particular in Figures 8 and 9, a feedthrough 59 is optionally likewise provided in the joint socket 51, by means of which the base part 10, in particular the shaft 14, can be guided from the outside 56 to the interior or inside 57 of the support frame 50. This feedthrough 59 is optionally arranged concentrically with the first joint axis A1. The feedthrough optionally completely surrounds the base part 10, in particular its shaft 14, in a particularly circular manner. The feedthrough 59 is optionally designed such that there is no contact between the support frame 50 and the base part 10 when the support frame 50 rotates relative to the base part 10. The feedthrough can have stop means, in particular guide means, which serve to guide the support frame relative to the base part during the rotation about the first joint axis. The stop means can for example abut in a guide manner against a counter-stop means against the base part, in particular against its shaft.

[0091] Optionally, this feedthrough 59 is designed to at least partially cover the feedthrough 39, in particular the feedthrough 39 of the intermediate socket embodied as an elongated hole, thereby preventing the ingress of dirt particles. In principle, it is conceivable to provide sealing means between the base part 1, in particular the shaft, and the lateral edges of the feedthrough 39 or 59 which have an at least partially sealing effect.

[0092] Optionally, this feedthrough 39 is embodied as an elongated hole extending in the direction of a pivoting axis A3 (see FIG. 2), as shown by way of example in this embodiment. This pivoting axis A3 represents the movement of the feedthrough or edge 82 (see FIG. 9), in particular the front edge 82, which moves in the direction of this pivoting axis A3. This pivoting axis A3 is arc-shaped, the arc being optionally formed so as to have a center on the second joint axis A2. Optionally, the feedthrough, in particular the front edge 82, moves along the pivoting axis A3 in an arc around the second joint axis A2.

[0093] In particular, the front edge 82 of this feedthrough can have blocking means, so that the pivot angle is limited by abutment of these blocking means against the base part 10, in particular its shaft or correspondingly provided counter-stop means. Optionally, these means are arranged diametrically with respect to the first joint axis A1 at the feedthrough.

[0094] 5 to 11, at least one upper bearing groove 80, optionally extending concentrically with the first joint axis A1, is provided in the inner wall 38 of the intermediate socket 36, in which the sliding ring 70 is mounted. In particular, the sliding ring 70 is optionally fixed against movement relative to the intermediate socket 36 in an upward direction, i.e. in the direction of the first joint axis A1.

[0095] As shown in figures 13 to 16 for another embodiment, it is alternatively possible that the joint head 12 has in its outer wall 19 a lower bearing groove 81, optionally extending concentrically with the first joint axis A1, in which the sliding ring 70 is mounted and, optionally, fixed against movement relative to the joint head 12 in the downward direction, i.e. along the first joint axis A1. The design of these bearing grooves has been described in particular in the introduction. The bearing grooves can optionally be used to fix the sliding ring to the component in which they are formed, so that the sliding ring moves along at least one axis together with the component of the bearing groove. This fixation can be uniaxial or multiaxial.

[0096] The sliding ring 70 optionally has fastening means 72 and the intermediate socket 36 or the joint head 12 (depending on the embodiment according to Figures 5 to 11 and 13 to 16) has counter-fastening means or vice versa, which engage with each other in such a way that the sliding ring 70 is fixed against rotation about the first joint axis A1 relative to the intermediate socket 36 or the joint head 12. The fastening means and the counter-fastening means can be designed such that the sliding ring is fixed against movements, in particular in the direction of the first joint axis A1, relative to the intermediate socket or the joint head. The above refers to an orientation in which the installation frame does not pivot about the second joint axis, i.e. the aforementioned neutral position.

[0097] Optionally, the fixing means 72 have at least one projection 71 protruding from the rotation axis A4 (see FIG. 12), optionally from the sliding ring plane of the sliding ring 70, and the counter fixing means 74 have at least one complementary projection receiver 73, or vice versa. In this embodiment, the projection receiver is a recess into which the projection 71 can be inserted, thereby fixing the sliding ring 70, in particular against rotation about the first joint axis (see FIG. 11). Depending on the design, the counter fixing means can be located on the joint head or on the intermediate socket. It is also conceivable to form the counter fixing means on the sliding ring, for example in the form of a recess, and to form the fixing means on the intermediate socket or on the joint head, for example in the form of a projection complementary to the recess. For such an embodiment, everything described above with respect to the fixing means and the counter fixing means applies.

[0098] It is conceivable that the counter fixing means 74 or the fixing means 72 are arranged or formed in the upper bearing groove on the intermediate socket 36 or in the lower bearing groove 81 of the joint head 12 .

[0099] In the embodiment shown herein according to Figures 5 to 16, the sliding ring is optionally embodied as an open sliding ring 70. In the embodiment according to Figures 1 to 4, the sliding ring is optionally embodied as a closed sliding ring. In the case of an open sliding ring 70, it is conceivable that at least one free end region 76 (see Figure 12) of the sliding ring 70 is embodied as a fastening means 72, optionally as a protrusion 71, and optionally bent away from the axis of rotation A4, optionally from the sliding ring plane of the sliding ring 70. It is also conceivable that the free end region 76 of the sliding ring is rounded.

[0100] As mentioned above, different designs of bearing grooves 80, 81 for the sliding rings are shown in figures 5 to 11 and 13 to 16, respectively. In the embodiment according to figures 13 to 16, at least one counter-fixing means 74 is embodied in the form of a projection receiver on the joint head 12, into which a complementary fixing means 72 or curved projection 71 of the sliding ring 70 can engage in a fixed manner.

[0101] As another example, figure 16 shows an embodiment in which at least one channel 90 is formed on the outer wall 19 of the joint head, which serves to remove contaminants in the running gap 20. This channel is covered by the sliding ring 70 to form a drainage space, so that contaminants, in particular particles, can also be drained downwards, in particular in the direction of the first joint axis A1. Corresponding structures can also be formed between the joint socket and the intermediate joint socket.

[0102] Optionally, the first and second joint axes intersect.

[0103] As can be seen in particular in Fig. 1 and Fig. 5 to 7, the cradle bearing assembly is designed such that at least one bearing means 32 of the installation frame 30 and at least one counter-bearing means 52 of the support frame 50 form at least one strip bearing, and it is optionally conceivable that the bearing means 32 has at least one, in particular arc-shaped, convex bearing arch 34 and / or the counter-bearing means 52 has at least one, in particular arc-shaped, concave bearing arch 54. These arches are force-coupled to one another, in particular in a sliding manner. When the installation frame moves relative to the support frame about the second joint axis A2, the bearing means and the counter-bearing means slide relative to one another. Optionally, the bearing means and the counter-bearing means form a guide. Lateral guide means 33, 53 can be provided for this purpose. The lateral guide means can form a guide between the installation frame and the support frame when the installation frame pivots about the second joint axis. The lateral guide means may provide guidance, in particular blocking, against movement of the installation frame relative to the support frame along the second joint axis.

[0104] It is also conceivable that the bearing means 32 and the counter-bearing means 52 are formed outside the area of ​​the joint socket 51, the intermediate socket 36 and the joint head 12. This is exemplarily illustrated in Fig. 1. In this embodiment, these externally arranged bearing means in particular comprise the output gear 31, which is force-coupled with actuating means, which are optionally arranged on the support frame. In particular, the bearing means are force-coupled to drive the gear. However, the output gear can also be designed without a bearing function.

[0105] It is also conceivable that at least one bearing means 32 is formed on the outer wall 38 of the intermediate socket 36 and at least one counter-bearing means 52 is formed on the inner wall 58 of the joint socket 51. Optionally, the bearing means and / or the counter-bearing means are integrally formed with their respective associated components, i.e. intermediate socket or joint socket.

[0106] 6 in particular shows that the at least one bearing means 32 and the at least one counter-bearing means 52 can have lateral guide means 33, 53, by which the fixing of the bearing means 32 to the counter-bearing means 52, and therefore optionally also the fixing of the installation frame to the support frame, is provided against force components acting in the direction of the second joint axis A2. The bearing means and the counter-bearing means can form a guide for a movement of the installation frame in one direction about the second joint axis. In the event of a force acting on the installation frame or the support frame in the direction of the second joint axis, these lateral guide means 33, 53 optionally prevent the joint socket from hitting the intermediate socket and / or maintain the relative movement gap 40.

[0107] It is conceivable that the arc axis of at least one bearing means 32 embodied as a concave bearing arc 34 and / or the arc axis of at least one counter-bearing means 52 embodied as a concave bearing arc 54 extend about an axis that is coaxial with the second joint axis A2. This means that the arches can, at least in some parts, surround the second joint axis in an arc. Each arch can have a common arc centre, optionally lying on the second joint axis.

[0108] Optionally, fixing means, optionally in the form of pre-tensioning means, here for example a compression spring 87, are provided which press the joint socket and / or the intermediate socket against the joint head and thus provide a constant bearing pressure between the intermediate socket, the sliding ring and the joint head.

[0109] As shown in particular in Figures 1 and 2, it is conceivable that the installation frame 30 is fixed to the support frame 50 against movements in the direction of the first joint axis A1 via fixing means, in particular a fixing pin 55, which optionally extends between the installation frame 30 and the support frame 50 parallel to the second joint axis A2 and is mounted on the support frame via an axial bearing means 59. Such fixing optionally ensures the cohesion of the components fixed by the fixing pin or fixing means, in particular after the overload clutch described above is triggered. In this embodiment, the fixing means, in particular the fixing pin 55 in the component 84, which is optionally also embodied as the bearing means 32, is mounted in an elongated hole (not shown). This slot also optionally extends in an arc around the second joint axis A2. When the installation frame 30 is pivoted relative to the support frame 50, the fixing means or fixing pin 55 can slide along a transverse direction to its extension axis. List of reference signs
