Abstract
Description
[0001] Drive device with a base body and with at least one
[0002] Rotation unit
[0003] The invention relates to a drive device with a base body and with at least one rotation unit, wherein the rotation unit is arranged at least rotatably mounted on the base body, wherein the rotation unit has at least one driven drive shaft, wherein the drive shaft drives at least one rotation body, wherein the rotation body has at least two flywheel weights, wherein the flywheel weights are arranged so as to be displaceable radially to the drive shaft, wherein the flywheel weights are arranged in pairs, wherein the flywheel weights are arranged on opposite sides of the drive shaft and wherein the flywheel weights are connected to one another at a fixed distance from one another.
[0004] Drive systems are used in a wide variety of applications, for example, for vehicles, remote-controlled vehicles, or autonomous vehicles. When operating land vehicles with drive wheels, hazards can arise due to aquaplaning, ice-covered road surfaces, or similar conditions when the tires come into contact with the road surface. Furthermore, tire wear can occur due to the constant contact of the tires with the road surface.
[0005] For example, DE 10 2019 126 489 A1 discloses a drive device comprising a base body and at least two rotation units, wherein the rotation units are arranged on the base plate in at least a rotatable manner, wherein the rotation units each have at least two rotation shafts driven in opposite directions of rotation. Each rotation shaft drives at least one rotation body, wherein the rotation planes of the rotation bodies of a rotation unit are arranged parallel to one another. Each rotation body has at least one flywheel, and the flywheel weights are each mounted so as to be displaceable radially relative to the rotation shaft. During one rotational section, one flywheel weight is located in the region of the drive shaft, and the second flywheel weight is in an unbalanced position.The flywheel weights can be moved radially to the rotation axis on the rotating bodies in such a way that an imbalance is created in one circular segment of the same rotation and that a balanced movement is possible in another circular segment of a rotation. The imbalances should be directed in the same direction for all rotating bodies and all rotating units, resulting in a single-directional momentum of the base body.
[0006] The precise and robust control and generation of the impulses of the flywheel weights is of great importance for the efficient function of the drive device due to the high acting forces.
[0007] The invention is based on the object of proposing a drive device of the type mentioned, in which a robust control of the impulses of the flywheel weights is possible in a simple manner.
[0008] This object is achieved by a drive device having the features of patent claim 1. Further developments and advantageous embodiments are specified in the subclaims.
[0009] In a drive device with a base body and with at least one rotation unit, wherein the rotation unit is arranged at least rotatably mounted on the base body, wherein the rotation unit has at least one driven drive shaft, wherein the drive shaft drives at least one rotation body, wherein the rotation body has at least two flywheels, wherein the flywheels are arranged displaceably radially to the drive shaft, wherein the flywheels are arranged in pairs, wherein the flywheels are arranged on opposite sides of the drive shaft and wherein the flywheels are connected to one another at a fixed distance from one another, it is essential to the invention that the rotation body has at least two pulse generators, that the rotation body has at least one linear guide for the linear guidance of the at least two pulse generators radially to the drive shaft,that the pulse generators are arranged on opposite sides of the drive shaft, that at least one spring element is arranged between each of the pulse generators and the drive shaft, that the spring elements are each designed to deflect the respective pulse generator along the linear guide, that the rotation unit has at least one link plate for controlling the distance of the pulse generators from the drive shaft during rotation of the drive shaft, and that the pulse generators are assigned to the flywheel weights in a pulse-transmitting manner.
[0010] The base body can, in particular, be a flat base plate. The rotation units are received by the base body at least so as to be rotatable relative to the base body. For example, the rotation units can also be pivotably and rotatably received. The pivotable holder can, in particular, be a gimbal suspension. For example, a base plate can have openings in which the rotation units are received. In addition, the rotation units are rotatably received in the openings of the base plate. The drive device can have three or more, preferably four or more, rotation units. The rotation body can, in particular, be disk-shaped, for example, circular as a rotation disk. In particular, the drive shaft for driving the rotation body can be arranged in the center of the rotation body.A rotating body can be set in rotation by means of the drive shaft. The drive shaft can be driven, for example, by an electric motor or similar. Each rotating body has at least two flywheels, each of which is mounted so as to be displaceable radially relative to the rotating shaft. In particular, the flywheels can be two flywheels of the same shape and mass that are connected to one another at a fixed distance from one another. During one section of the rotating body's rotation, one flywheel is located on or in the area of the drive shaft, and the second flywheel is in an unbalanced position. In the balanced or almost balanced state, both flywheels are, for example, at the same distance from the drive shaft.When using two flywheel weights connected to each other at a fixed distance from each other, the flywheel weights can each have the same distance from the drive axis when balanced or almost balanced, i.e. in a semicircle of rotation. The flywheel weights can, for example, be mounted so as to be displaceable on guide elements such as guide rails or slide rails, with the guide elements being arranged on the rotating bodies radially from the axis of rotation. The flywheel weights can be moved radially on the rotating bodies to the axis of rotation in such a way that an imbalance occurs in a circular segment, i.e. in one angular section of rotation, of the same revolution, and that a balanced or almost balanced movement is possible in a further angular section of the rotation.Preferably, the imbalances are directed in the same direction and cycled the same on all rotating bodies and all rotating units of a drive device. For example, flywheel weights can be arranged parallel to one another on both sides of the rotating body, which can be moved synchronously and congruently. In order to bring the flywheel weights into an at least approximately balanced or unbalanced position, the rotating body has impulse bodies. To guide the impulse generators, the rotating body has a linear guide, along which the impulse generators can be moved in the radial direction to the drive shaft. The impulse generators transmit an impulse, for example by impact, to the respective flywheel weight. By moving them along the linear guide, the distance of the impulse generators from the drive shaft and thus from the axis of rotation and also the respective spring tension of the spring elements is controlled.By controlling one pulse generator in a rotational section, i.e. in an angular range of rotation, to a position further away from the axis of rotation, while the other pulse generator is in a position closer to the drive shaft, a pulse can be achieved with corresponding pulse transmission to the flywheel weights in one direction. Starting from the drive shaft, the linear guide of the rotating body extends radially on two opposite sides. For example, the linear guide can be formed by a slot-like recess in the rotating body, in particular in the rotating disk, wherein the pulse generators are guided in the linear guide so that they can be displaced in the radial direction. The pulse generators can therefore be displaced in the linear guide along the radius of the rotating disk.At least two pulse generators are assigned to the rotating body, with the pulse generators arranged on a radius on opposite sides of the drive shaft. Spring elements are arranged between the pulse generators and the drive shaft. The spring elements can in particular be compression springs. The spring elements are arranged in such a way that when the spring elements are relaxed, i.e. when the spring force is released, the pulse generators are pushed away from the drive shaft in a radial direction. To bring a pulse generator closer to the drive shaft, the spring element must be compressed and thus the spring force is applied. At least one link plate is assigned to the rotating body to control the distance between the pulse generators and the drive shaft.The link plate can in particular be aligned parallel to the guide body, i.e. in particular to the guide plate, wherein the plane spanned by the guide body is arranged parallel to the plane spanned by the link plate. The link plate has a link guide for the pulse generators. The link guide can in particular be formed by a guide opening into which guide pins of the pulse generators can engage. The guide pins can, for example, be cylindrical and arranged perpendicular to the plane spanned by the rotating plate, i.e. by the rotating body. The rotating body is set in rotation relative to the link plate by the drive shaft, so that the guide pins of the pulse generators are moved along the inner edge of the guide opening. Depending on the shape of the guide opening, the pulse generators are moved along the linear guide during rotation of the rotating body.In order to achieve a directed impulse from the drive device and impulse transmission from the impulse generators to the flywheel weights, one impulse generator is moved close to the drive shaft during one section of rotation, whereby the spring element is compressed. The other impulse generator, arranged opposite the drive shaft, is meanwhile in a position further away from the drive shaft. During one section of rotation, the change occurs in that the impulse generator, which is further away from the drive shaft, is moved through the guide opening in the link plate towards the drive shaft, whereby the spring force must be applied to compress the spring element. At essentially the same moment, the other impulse generator, which was closer to the drive shaft, is moved away from the drive shaft through the guide opening.This results in a sudden release of the spring force of the spring element, so that the pulse generator is suddenly moved away from the drive shaft due to the centrifugal force acting during rotation and supported by the spring element. The pulse from the pulse generator is transferred, for example by impact, to the radially displaceable flyweights. The pulse transmission from a pulse generator can take place synchronously and congruently to two flyweights arranged on either side of the rotating body. For example, when the spring element is released, the pulse from the pulse generator can be transferred to a first flyweight by impact, so that this is accelerated to a position on the outer radius of the rotating body. The other second flyweight, connected to the first flyweight at a fixed distance from each other, is moved closer to the drive shaft.The spring elements of the pulse generators dampen the flywheels before they reach their respective end positions. This creates a directed pulse for the entire drive mechanism, which, with appropriate pulse transmission, can lead to a movement of the drive mechanism. For this purpose, the drive mechanism can, in particular, comprise several rotating units that can generate a pulse when controlled in parallel. The direction of the pulse can be controlled by rotating the cam discs.
[0011] In a further development of the invention, the rotating body is disk-shaped, the rotating body and the at least one link plate are arranged parallel to one another, and the drive shaft of the rotating body is arranged perpendicular to the planes spanned by the rotating body and the at least one link plate. The rotating body is disk-shaped, preferably circular. The rotating body and the link plate can be arranged parallel to one another, so that the guide pins of the pulse generator, which extend perpendicular to the plane spanned by the link plate and the plane spanned by the rotating body, can engage in the guide opening of the link plate.When the rotating body rotates relative to the link plate, the guide pins are guided along the inner edge of the guide opening of the link plate, so that the respective distance of the pulse generators and thus indirectly of the flywheel weights to the drive shaft can be controlled by the link plate during rotation.
[0012] In one embodiment of the invention, the linear guide is designed as a guide slot. The linear guide of the rotating body can be designed as a slot-like recess. The slot-like recess extends radially in the rotating body from the drive shaft, i.e., in the direction of the radius, to two opposite sides of the drive shaft.
[0013] In one embodiment of the invention, the rotating body is mounted so as to be rotatable about the rotational axis of the drive shaft independently of the axis of rotation of the link plate. The rotating body is driven by the drive shaft about its rotational axis, whereby the rotating body is moved independently of the at least one link plate. The independent rotation of the rotating body relative to the link plate enables control of the momentum.
[0014] In one embodiment of the invention, the link plate has a guide opening, and the inner edge of the guide opening is designed to control the movement of the pulse generators along the linear guide. The guide pins of the pulse generators engage in the guide opening and are moved along the inner edge of the guide opening during the rotation of the rotating body relative to the link plate. The guide pins are pressed against the inner edge of the guide opening by the spring force of the spring elements. Depending on the shape of the guide opening, the pulse generators can thus be moved along the linear guide of the rotating body. The inner edge of the guide opening can, for example, have a friction-reducing coating.The guide opening can, in particular, be designed such that the spring element is first strongly compressed over a rotational section, i.e., over an angular section, and then compressed less strongly over a rotational section of equal length, i.e., over an equally large angular section of rotation. This is intended to keep the force required constant during a rotation. The spring force required to compress one spring element increases until the spring element is fully compressed.
[0015] In one embodiment of the invention, the distance between the inner edge of the guide opening and the drive shaft varies along the inner edge, and the distance is selected depending on the spring force of the spring elements. The guide opening can, in particular, be designed such that a relaxed spring element, when re-tensioned by applying the spring force, is initially strongly compressed in a circular section and then compressed less strongly over a circular section of the same length. This is intended to keep the force exerted by driving the drive shaft constant during rotation. The spring force required to compress one spring element increases until the spring element is completely compressed.In the first section, the guide opening has a greater pitch relative to the drive shaft, which causes the spring element to be compressed more strongly over a smaller angular section of rotation. Further along, the pitch of the outer edge of the guide opening flattens, meaning the spring element is compressed less strongly over the same angular section as in the first section. This ensures a constant force is required to compress the spring element during rotation.
[0016] In one embodiment of the invention, the pulse generators each have at least one guide pin, and the guide pins engage in the guide opening of the link plate. The pulse generators each have at least one guide pin, which is arranged perpendicular to the plane spanned by the rotating body or the plane spanned by the guide slot. Due to the perpendicular arrangement to the rotating body, a guide pin can engage in the guide opening of the link plate, which is arranged parallel to the rotating body. In one embodiment of the invention, the shape of the guide opening is essentially formed by two essentially semicircular surfaces, wherein a first essentially semicircular surface has a larger radius than a second essentially semicircular surface.The idea is that during rotation of the rotating body, a pulse generator and thus a flywheel is initially located at a position further away from the drive shaft and then moved to a position closer to the drive shaft. In this way, two essentially semicircular surfaces are used as the shape of the guide opening in the link plate. The essentially semicircular surfaces that make up the guide opening in the link plate can also be hyperbolas, ellipses or similar. If the guide pin of the pulse generator moves along the inner edge of the larger, essentially semicircular surface, the pulse generator is further away from the rotating shaft. In the section in which the guide opening is defined by the smaller, essentially semicircular surface, the pulse generator is moved along the linear guide towards the drive shaft.The diameters of the two essentially semicircular surfaces are arranged essentially opposite one another, in particular lying on a line. The centers or focal points of the essentially semicircular surfaces, i.e. the points around which the respective radius of the semicircle or ellipse is constructed, are also arranged on this line, which can also have a non-straight shape. The rotation axis of the drive shaft can also lie on this line. The circle centers are offset on this line. By arranging the centers or focal points and choosing the respective radii, the position of the pulse generators can be adjusted during the rotation of the rotating body. The larger the radius of a semicircle or ellipse, the further the flywheel is arranged from the drive shaft.In one embodiment of the invention, the circle centers of the substantially semicircular surfaces are arranged on one and the same line, and the circle centers are offset from one another along the line. The arrangement of the semicircle centers, or the focal points of ellipses, on a line and the offset arrangement from one another enables a transition of the movement of the pulse generators from a position close to the drive shaft to a position remote from the drive shaft.
[0017] In one embodiment of the invention, the radius of the first larger, substantially semicircular surface is considerably larger than the radius of the smaller, second, substantially semicircular surface. The ratio of the radii of the two substantially semicircular surfaces to one another can be used to determine the ratio of the distances of the pulse generators in the position further away from the drive shaft to the position close to the drive shaft. In particular, the radius of the small semicircular surface can be adapted to the minimum space required by a compressed spring element between the drive shaft and the pulse generator. The radii of the semicircular surfaces thus determine the respective spring tension between the pulse generators and the drive shaft.
[0018] In a preferred embodiment of the invention, the rotation unit has two guide plates. The guide plates are arranged parallel to the rotating body on both sides, and the guide openings of the guide plates are arranged congruently. Preferably, a pulse generator has a guide pin that protrudes from the plane spanned by the rotating body on both sides and engages the guide openings of the guide plates arranged there. The guide openings of the guide plates are arranged congruently, so that the guide pin is guided equally by both guide plates. This provides significantly more stable guidance of the pulse generator.
[0019] In one embodiment of the invention, each rotation unit is assigned a second rotation unit with drive shafts driven in opposite directions of rotation. To achieve the most stable drive of the drive device, the rotation units are designed in pairs, with the directions of rotation being opposite. This results in a more stable drive of the drive device.
[0020] In one embodiment of the invention, at least two flywheel weights are each arranged so as to be slidingly mounted on a guide element. For example, a guide element, in particular a slide rail, can be arranged around the linear guide of the pulse generators, so that the flywheel weights, which are connected to one another at a fixed distance from one another, can be arranged so as to be slidingly displaceable parallel to the pulse generators on this guide element. The guide element can also have ball bearings, plain bearings or similar for mounting. The flywheel weights can be pushed by the pulse generators or by the guide pins of the pulse generators, so that the pulse is transferred from the pulse generators to the flywheel weights. The connection between the flywheel weights at a fixed distance from one another can be formed, for example, by a rod system or the like. For example, the connection at a fixed distance from one another can be rigid.In particular, the rigid connection ensures that the distance between the flywheels is always the same. Thus, an impulse transmitted to a first flywheel is directly transferred to the second flywheel.
[0021] In a further development of the invention, the rotating body has a plurality of sliding elements, and the guide elements each extend radially on both sides of the drive shaft. The rotating body can have a plurality of flywheels. The flywheels are connected to one another in pairs at a fixed distance from one another, for example via a rod assembly. Two flywheels can be arranged to slide on a sliding element. The guide elements each extend radially on both sides of the drive shaft. The guide elements are preferably arranged at the same distance from one another; in particular, the angles between adjacent guide elements are the same. During the rotation of the rotating body relative to the link disks, the pulse generator is moved such that it impacts the flywheels one after the other. In this way, pulses can be transmitted to a plurality of flywheels by two rotating pulse generators.Guide elements can also be arranged, in particular congruently, on both sides of the rotating body.
[0022] Furthermore, the rotating body can have a plurality of linear guides, each extending radially on both sides of the drive shaft. In particular, the linear guides can be evenly distributed on the rotating body. The angles between two adjacent linear guides can be the same. A linear guide with two pulse generators can be assigned to two flywheel weights arranged on one side of the rotating body or to two pairs of flywheel weights, one pair of flywheel weights on each side of the rotating body.
[0023] In one embodiment of the invention, the pulse generators are arranged radially between the drive shaft and the respective flywheel. Arranging the pulse generators radially between the drive shaft and the flywheel enables the transmission of the pulse from the pulse generators or from the guide pins of the pulse generators to the flywheel. For example, when the pulse generator is removed from the drive shaft, i.e., when the respective spring element is released, the pulse generator can move the flywheel to a position on the outer radius of the rotating body. Arranging the pulse generator between the drive shaft and the flywheel allows the flywheel to receive a pulse from the pulse generators.
[0024] An exemplary embodiment of the invention is illustrated in more detail in the drawing below. The schematic representations show in detail:

[0026] backdrop discs in a perspective view;

[0032] Fig. 1 shows a rotation unit 1 with a disk-like rotation body 2 and two link plates 3 arranged parallel to the rotation body 2. The rotation body 2 is set in rotation via a drive shaft 4. The rotation body 2 has a linear guide 5 in which pulse generators 6 are guided. The linear guide 5 is designed as a slot-like recess in the rotation body 2 and extends in the radial direction to two opposite sides of the drive shaft 4. Spring elements 7, which can be designed as compression spring elements, are arranged between the pulse generators 6 and the drive shaft 4. The spring elements 7 are designed such that the pulse generators 6 are pressed away from the drive shaft 4 along the linear guide 5 by the spring elements 7. Link plates 3 are arranged parallel to the rotation body 2 on both sides of the rotation body 2.The rotating body 2 is rotated relative to the link plates 3 by the drive shaft 4. The pulse generators 6 each have guide pins 9 that are arranged perpendicular to the plane of rotation, i.e., to the plane spanned by the rotating body 2. The guide pins 9 engage in the guide openings 8 of the link plates 3 and, during the rotation of the rotating body 2, are moved along the inner edges of the guide openings 8. The guide pins 9 are pressed against the inner edge of the guide opening 8 by the acting spring force of the spring elements 7. The distance of the pulse generators 6 from the drive shaft 4 along the linear guide 5 is controlled by the guide openings 8 of the link plates 3.Thus, one pulse generator can be moved closer to the drive shaft 4, while the other pulse generator is moved essentially simultaneously, assisted by the centrifugal force and the relaxing spring force of the spring element 7, to a position farther away from the drive shaft 4. This allows a directed pulse to be generated.
[0033] Fig. 2 shows a side view of a rotation unit 1 according to Fig. 1. Identical components are provided with the same reference numerals. The shape of a guide opening 8 of a link plate 3 is essentially formed by the surface areas of two semicircles 10, 11. The larger section 10 moves the pulse generator 6 to a position farther away from the drive shaft 4. The smaller section 11 moves the corresponding pulse generator 6 further in the direction of the drive shaft 4 during the rotation of the rotating body 2 along the linear guide 5.
[0034] Fig. 3 shows a further side view of the rotation unit 1 according to Fig. 1. Identical components are provided with the same reference numerals. The link plates 3 can be adjusted so that they can rotate parallel to one another, in particular such that the guide openings 8 remain congruent in order to control the direction of the directed impulse. Fig. 4 shows a rotation unit 1 according to Fig. 1. The rotation body 2 has flywheels 12, 13 which are mounted on a guide element, here a slide rail 14. The slide rail 14 is arranged around the linear guide 5. The flywheels 12, 13 are connected to one another at a fixed distance from one another, in particular by a rigid connection 15, which can be formed, for example, by a rod assembly. Due to the rigid connection 15, the flywheels 12, 13 are always at the same distance from one another.The pulse generator 6 transmits a pulse to the flywheel 12, so that it is now positioned at the outer radius of the rotating body 2. Accordingly, the flywheel 13 is moved toward the drive shaft 4, whereby the spring element 7 between the flywheel 13 and the drive shaft 4 is again tensioned. During the further movement, a pulse would now be transmitted to the flywheel 13 by the pulse generator 6. This would cause the spring element 7 to relax.
