Description

[Technical Field]

[0001] The present invention relates to a drive device having a body and having at least one rotary unit, The rotating unit has at least one driven drive shaft, wherein the drive shaft drives at least one rotating body, wherein the rotating body has at least two swing weights, wherein the swing weights are radially movably arranged on the drive shaft, wherein the swing weights are arranged in pairs, wherein the swing weights are arranged on both sides of the drive shaft, and wherein the swing weights are connected to each other at a certain distance from each other. [Background technology]

[0002] Drive systems are used in a wide range of applications, for example, for vehicles and remote-controlled or autonomous vehicles. When operating a land vehicle with drive wheels, tire contact with the road can create hazards due to aquaplaning, icy roads, etc. Furthermore, persistent tire contact with the road surface can result in signs of tire wear and tear.

[0003] For example, DE10 2019 126 489A1 discloses a drive device having a main body and at least two rotating units, where the rotating units are at least rotatably arranged on a base plate and have at least two rotating shafts driven in opposite rotational directions. Each rotating shaft drives at least one rotating body, where the rotational planes of the rotating bodies of the rotating units are arranged parallel to each other. Each rotating body has at least one swing weight, which is attached radially to the rotating shaft. In one section of rotation, one swing weight is located in the area of ​​the drive shaft, and a second swing weight is in an unbalanced position. The swing weight can be shifted radially relative to the rotation axis on the rotating body, so that an imbalance exists in the same circular segment of rotation and balanced movement is possible in another circular segment of rotation. The imbalance should be in the same direction for all rotating bodies and all rotating units, resulting in a pulse of the main body in one direction.

[0004] Accurate and robust control and generation of the swing weight pulse is very important for the efficient functioning of the drive system due to the high levels of effort. Summary of the Invention

[0005] The object of the invention is to propose a drive device of the type mentioned above, in which a robust control of the pulses of the swing weight is possible in a simple manner.

[0006] This problem is solved by providing a drive device having the features of claim 1. Further and preferred embodiments are specified in the dependent claims.

[0007] For a drive device having a body and at least one rotating unit, the rotating unit is at least rotatably arranged and attached to the body, wherein the rotating unit has at least one driven drive shaft, wherein the drive shaft drives at least one rotating body, wherein the rotating body has at least two swing weights, wherein the swing weights are radially movably arranged on the drive shaft, wherein the swing weights are arranged in pairs, wherein the swing weights are arranged on both sides of the drive shaft, and wherein the swing weights are connected to each other at a certain distance from each other. The essence of the present invention is that the rotating body has at least two pulse generators, the rotating body has at least one linear guide for linearly guiding the at least two pulse generators in a radial direction relative to the drive shaft, the pulse generators are arranged on both sides of the drive shaft, at least one spring element is arranged between the pulse generators and the drive shaft, each spring element is designed to deflect each pulse generator along the linear guide, the rotating unit has at least one link plate for controlling the distance between the pulse generators and the drive shaft during rotation of the drive shaft, and the pulse generators are associated with a swing weight to transmit pulses.

[0008] In particular, the body may be a flat base plate. The rotating units are held on the body so as to be at least rotatable relative to the body. For example, the rotating units may be held swivelably and rotatably. In particular, the swivel mount may be a gimbal suspension. For example, the base plate may have openings in which the rotating units are held. The rotating units are rotatable within the openings of the base plate. The drive device may have three or more, preferably four or more, rotating units. In particular, the rotating body may be disk-shaped, e.g., circular, like a rotating disk. In particular, a drive shaft for driving the rotating body may be positioned at the center point of the rotating body. The rotating body can be rotated by the drive shaft. The drive shaft may be driven, for example, by an electric motor or the like. Each rotating body has at least two swing weights, each mounted so as to be radially movable relative to the rotating shaft. In particular, the swing weights may be two swing weights of the same shape and mass connected to each other at a fixed distance from each other. In one section of rotation of the rotating body, one swing weight is located on or within the area of ​​the drive shaft, and the second swing weight is in an unbalanced position. In a balanced or nearly balanced state, for example, both swing weights have the same distance from the drive shaft. When using two swing weights connected to each other at a fixed distance from each other, the swing weights can each be balanced or nearly balanced, i.e., have the same distance from the drive shaft in a semicircle of rotation. The swing weights can be mounted on guide elements, such as guide rails or slide rails, where the guide elements are arranged radially on the rotating body starting from the rotation axis. The swing weights can be shifted radially relative to the rotation axis on the rotating body, so that an imbalance exists in the same circular segment of rotation, i.e., an angular section of rotation, and balanced or nearly balanced movement is possible in a further angular section of rotation.Preferably, all rotating bodies and all unbalances of the rotating units of the drive are oriented in the same direction and clocked in the same way. For example, swing weights can be arranged parallel to each other on both sides of the rotating body and moved synchronously in the same harmony. The rotating body has a pulse body to place the swing weights in at least approximately balanced or unbalanced positions. To guide the pulse generators, the rotating body has a linear guide along which the pulse generators are movable radially relative to the drive shaft. The pulse generators transmit pulses to the respective swing weights, for example, by colliding with each other. By moving along the linear guide, the distance between the pulse generators and the drive shaft, and thus the rotation axis, as well as the spring tension of each of the spring elements, is controlled. Pulses can be achieved in one direction within the rotation section, i.e., within the angular range of rotation, by controlling one pulse generator to be positioned further away from the rotation axis and the other pulse generator to be positioned closer to the drive shaft, and the appropriate pulses are transmitted to the swing weights. Starting from the drive shaft, the linear guides of the rotating body extend radially on two opposite sides. For example, the linear guide can be formed by a slot-like recess in a rotating body, particularly a rotating disk, in which the pulse generator is guided radially within the linear guide. Thus, the pulse generator can move along the radius of the rotating disk within the linear guide. At least two pulse generators are associated with the rotating body, where the pulse generators are disposed on opposite radii relative to the drive shaft. A spring element is disposed between the pulse generator and the drive shaft. The spring element may be, in particular, a compression spring. The spring element is disposed such that, when the spring element is released, i.e., when the spring force is released, the pulse generator is pushed radially away from the drive shaft. To move the pulse generator closer to the drive shaft, the spring element must be compressed, thereby applying the spring force. At least one link plate is associated with the rotating body to control the distance between the pulse generator and the drive shaft.In particular, the link plate may be aligned parallel to the guide body, i.e. in particular the guide disc, wherein the plane spanned by the guide body is arranged parallel to the plane spanned by the guide disc. The link plate has a sliding guide for the pulse generator. The sliding guide can be designed with a guide opening through which the guide pin of the pulse generator can reach. For example, the guide pin can be cylindrical and arranged perpendicular to the plane stretched by the rotating disk, i.e., the rotating body. The rotating body is rotated by the drive shaft relative to the link plate so that the guide pin of the pulse generator moves along the inner edge of the guide opening. Depending on the shape of the guide opening, the pulse generator moves along a linear guide during the rotation of the rotating body. To achieve directed pulses from the drive unit and pulse transmission from the pulse generator to the swing weight, the pulse generator is moved closer to the drive shaft in a section of rotation, where the spring element is compressed. Meanwhile, the other pulse generator located on the opposite side of the drive shaft is positioned further away from the drive shaft. During one section of rotation, the change is made by moving the pulse generator located further away from the drive shaft through the guide opening in the link plate toward the drive shaft, where a spring force must be applied to compress the spring element. At approximately the same time, the pulse generator closer to the drive shaft is moved away from the drive shaft through the guide opening. This causes the spring element to suddenly release its spring force, causing the pulse generator to suddenly move away from the drive shaft and be supported by the spring element due to centrifugal force acting during rotation. The pulse from the pulse generator is transmitted to a swing weight that can move radially, for example, by collision between the two. The pulse generator pulse transmission can be synchronized with two swing weights located on both sides of the rotor. For example, when the spring element is relaxed, the pulse from the pulse generator is transmitted to the first swing weight by collision between the two and accelerated to a position on the outer diameter of the rotor. The other swing weight, connected at a certain distance from the first swing weight, moves closer to the drive shaft. The spring element of the pulse generator damps the swing weight before it reaches its respective end position. This achieves directional pulses for the entire drive unit, and when the pulses are transmitted appropriately, it can cause the drive unit to move.For this purpose, the drive can have, in particular, several rotary units capable of generating pulses that are controlled in parallel with one another, the pulse direction being controlled by rotating the link plates.

[0009] In a further embodiment of the invention, the rotor is designed as a disk, the rotor and at least one link plate are arranged parallel to one another, and the drive shaft of the rotor is arranged perpendicular to the plane spanned by the rotor and the at least one link plate. The rotor is disk-shaped, preferably circular. The rotor and the link plate may be arranged parallel to one another, so that a guide pin of the pulse generator, extending perpendicular to the plane spanned by the link plate and the plane spanned by the rotor, can engage in a guide opening in the link plate. When the rotor rotates relative to the link plate, the guide pin is guided along the inner edge of the guide opening in the link plate, so that the respective distances of the pulse generators, and therefore indirectly the respective distances of the swing weights relative to the drive shaft, can be controlled by the link plate during rotation.

[0010] In one embodiment of the present 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, which extends radially from the drive shaft in the rotating body, i.e., radially to two opposite sides of the drive shaft.

[0011] In one embodiment of the present invention, the rotor is mounted about an axis of rotation of the drive shaft independent of the axis of rotation of the link plates. The rotor is driven about its axis of rotation by the drive shaft, where the rotor is moved independently of at least one link plate. The independent rotation of the rotor relative to the background disk allows for pulse control.

[0012] In one embodiment of the present invention, the link plate has a guide opening, the inner edge of which is designed to control the movement of the pulse generator along the linear guide. The guide pin of the pulse generator grips the guide opening and moves along the inner edge of the guide opening relative to the link plate during rotation of the rotating body. In this case, the guide pin is pressed against the inner edge of the guide opening by the spring force of the spring element. Therefore, depending on the shape of the guide opening, the pulse generator can move along the linear guide of the rotating body. The inner edge of the guide opening may have, for example, a friction-reducing coating. In particular, the guide opening may be designed so that the spring element is first compressed strongly on the rotating section, i.e., within the angular section, and then compressed more weakly on the rotating section of the same length, i.e., within the angular section of the same size of rotation. This is intended to keep the effort required during rotation the same. The spring force required to compress one of the spring elements increases until the spring element is fully compressed.

[0013] In one embodiment of the present invention, the distance between the drive shaft and the inner edge of the guide opening varies as the inner edge progresses, with the distance selected depending on the spring force of the spring elements. In particular, the guide opening can be designed so that when one relaxed spring element is re-tensioned by applying a spring force, it is first compressed strongly in a circular section and then compressed more weakly in a circular section of the same length. This is intended to ensure that the force applied by the drive shaft remains the same during rotation. The spring force required to compress one of the spring elements increases until the spring element is fully compressed. In the first section, the guide opening has a greater slope relative to the drive shaft, which compresses the spring element more strongly in smaller angular sections of rotation. As the movement progresses, the slope of the outer edge of the guide opening gradually flattens, so the spring element is less compressed in the same angular section as in the first area. This creates a constant amount of force to compress the spring element during rotation. In one embodiment of the present invention, each pulse generator has at least one guide pin that reaches into a guide opening in the link plate. The pulse generators each have at least one guide pin that is arranged perpendicular to the plane spanned by the rotor or the plane spanned by the guide slot. By being arranged perpendicular to the rotor, the guide pin can reach into the guide opening in the link plate that is arranged parallel to the rotor.

[0014] In one embodiment of the present invention, the shape of the guide opening is substantially formed by two substantially semicircular surfaces, where the first substantially semicircular surface has a larger radius than the second substantially semicircular surface. The pulse generator, and therefore the swing weight, is first positioned farther from the drive shaft during rotation of the rotating body and then moved closer to the drive shaft. This allows two substantially semicircular surfaces to be used as the shape of the guide opening of the link plate. The substantially semicircular surface forming the guide opening of the link plate may be hyperbolic, elliptical, or the like. When the guide pin of the pulse generator moves along the larger, substantially semicircular inner edge, the pulse generator moves further away from the rotating shaft. In the section of the guide opening defined by the smaller, substantially semicircular surface, the pulse generator is moved along the linear guide to the drive shaft. The two substantially semicircular diameters are arranged substantially opposite each other, and in particular, are on a straight line. On this line, which may have a non-linear shape, the center points or foci of the substantially semicircular surface, i.e., the points around which the respective radii of the semicircles or ellipses are constructed, are also positioned accordingly. The rotation axis of the drive shaft also lies on this line. The center points of the circles are staggered on this line. By positioning the center points or foci and selecting the respective radii, the position of the pulse generator can be adjusted during rotation of the rotor. The larger the radius of the semicircle or ellipse selected, the farther the swing weight will be from the drive shaft.

[0015] In one embodiment of the present invention, the centers of the circles of the substantially semicircular surface are collinear and the centers of the circles are offset from one another along a line. The alignment of the centers of the semicircles or foci of the ellipses along a line and offset from one another allows for translation of the pulse generator from a position closer to the drive shaft to a position further from the drive shaft.

[0016] In one embodiment of the present invention, the radius of the first, larger, substantially semicircular surface is significantly larger than the radius of the second, smaller, substantially semicircular surface. The ratio of the radii of the two substantially semicircular surfaces to each other can be used to determine the ratio of the distance of the pulse generator at a position farther from the drive shaft to the distance of the pulse generator at a position closer to the drive shaft. In particular, the radius of the smaller semicircular surface can be adapted to the minimum space required by the compressed spring element between the drive shaft and the pulse generator. Thus, the radius of the semicircular surface determines the respective spring tension between the pulse generator and the drive shaft.

[0017] In a preferred embodiment of the present invention, the rotating unit has two link plates, which are arranged parallel to the rotating body and have aligned guide openings. The pulse generator preferably has guide pins that protrude from both sides of the rotating body's plane and fit into the guide openings of the link plates located there. The guide openings of the link plates are aligned so that the guide pins are guided equally by both link plates. This provides extremely stable guidance for the pulse generator.

[0018] In one embodiment of the present invention, each rotating unit is assigned a second rotating unit with a drive shaft driven in the opposite direction of rotation. To achieve the most stable drive of the drive unit, the rotating units are designed in pairs, with the rotation directions running in opposite directions. This makes the drive unit more stable.

[0019] In one embodiment of the present invention, at least two swing weights are arranged in a sliding position on a guide element. For example, a guide element, particularly a slide rail, may be arranged around a linear guide of the pulse generator, so that the swing weights, connected to each other at a fixed distance from each other, can be arranged on this guide element in a sliding manner parallel to the pulse generator. For bearing purposes, the guide element may also have ball bearings, plain bearings, etc. The swing weights can be triggered by the pulse generator or by a guide pin of the pulse generator, so that pulses are transmitted from the pulse generator to the swing weights. The connection between the swing weights at a fixed distance from each other can be formed, for example, via a linkage or the like. For example, the connection can be rigidly formed at a fixed distance from each other. In particular, a rigid connection can ensure that the distance between the swing weights is always equal. This allows a pulse transmitted to a first swing weight to be directly transmitted to a second swing weight.

[0020] In a further embodiment of the present invention, the rotating body has multiple sliding elements, and the guide elements extend radially on both sides of the drive shaft. The rotating body may have multiple swing weights. The swing weights are connected in pairs at a fixed distance from each other, for example, via a linkage. Two swing weights may be arranged on the sliding elements. The guide elements extend radially on both sides from the drive shaft. Preferably, the guide elements are arranged at the same distance from each other, and in particular, the angle between adjacent guide elements is the same. During rotation of the rotating body relative to the link plate, the pulse generator moves so as to collide with the swing weights one after another. This allows pulses to be transmitted to multiple swing weights by two rotation pulse generators. The guide elements may also be arranged on both sides of the rotating body, in particular, coincidentally.

[0021] Furthermore, the rotating body may have multiple linear guides, each extending radially on either side of the drive shaft. In particular, the linear guides may be evenly distributed on the rotating body. The angle between two adjacent linear guides may be the same. Two swing weights arranged on one side of the rotating body, or two swing weight pairs arranged one on each side of the rotating body, may be associated with the linear guides having two pulse generators.

[0022] In one embodiment of the present invention, the pulse generators are disposed radially between the drive shaft and each swing weight. By disposing the pulse generators radially between the drive shaft and the swing weight, pulses from the pulse generators or from the guide pins of the pulse generators can be transmitted to the swing weights. For example, when the pulse generators move away from the drive shaft, i.e., when the respective spring elements are relaxed, the swing weights can be moved to a position on the outer diameter of the rotating body. By disposing the pulse generators between the drive shaft and the swing weights, the swing weights can receive pulses from the pulse generators. [Brief explanation of the drawings]

[0023] In the following, embodiments of the invention are shown in detail in the drawings. In detail, the schematic diagram shows: [Figure 1] FIG. 1 is a perspective view of a rotating unit having a rotating body and two link plates. [Figure 2] FIG. 2 is a side view of the rotary unit according to FIG. [Figure 3] FIG. 3 is another side view of the rotary unit according to FIG. [Figure 4] FIG. 4 shows a rotating unit according to FIG. 1 with a swing weight and a slide rail. DETAILED DESCRIPTION OF THE INVENTION

[0024] FIG. 1 shows a rotating unit 1, which includes a disk-shaped rotor 2 and two link plates 3 arranged parallel to the rotor 2. The rotor 2 is rotated by a drive shaft 4. The rotor 2 has a linear guide 5, in which a pulse generator 6 is guided. The linear guide 5 is designed as a slot-like recess in the rotor 2 and extends radially to two opposite sides of the drive shaft 4. A spring element 7, which may be designed as a compression spring element, is arranged between the pulse generator 6 and the drive shaft 4. The spring element 7 is designed so that the pulse generator 6 is pushed along the linear guide 5 away from the drive shaft 4 by the spring element 7. Link plates 3 are arranged parallel to the rotor 2 on both sides. The rotor 2 rotates relative to the link plates 3 by the drive shaft 4. Each pulse generator 6 has a guide pin 9, which is arranged perpendicular to the plane of rotation, i.e., the plane spanned by the rotor 2. The guide pin 9 is held in the guide opening 8 of the link plate 3 and moves along the inner edge of the guide opening 8 during rotation of the rotating body 2. In this case, the guide pin 9 is pressed against the inner edge of the guide opening 8 by the acting spring force of the spring element 7. The distance of the pulse generator 6 relative to the drive shaft 4 is controlled along the linear guide 5 via the guide opening 8 of the link plate 3. As a result, one pulse generator is moved closer to the drive shaft 4, while the other pulse generator is simultaneously moved farther away from the drive shaft 4, essentially supported by centrifugal force and the relaxing spring force of the spring element 7. This makes it possible to generate directional pulses.

[0025] 2 shows the rotary unit 1 according to FIG. 1 in a side view. Identical components are provided with identical reference numerals. The shape of the guide opening 8 in the background disk 3 is substantially formed by the surface area of ​​two semicircles 10, 11. By means of the larger section 10, the pulse generator 6 is moved further away from the drive shaft 4. By means of the smaller section 11, the corresponding pulse generator 6 is moved further along the linear guide 5 in the direction of the drive shaft 4 during rotation of the rotor 2.

[0026] In Figure 3, the rotary unit 1 is shown in a further side view according to Figure 1. Identical components are given the same reference numerals. The link plates 3 can be rotated parallel to one another, in particular so that the guide openings 8 remain aligned in order to control the direction of the directed pulses.

[0027] FIG. 4 shows the rotating unit 1 according to FIG. 1. The rotating body 2 has swing weights 12, 13 arranged on guide elements, in this case, slide rails 14. The slide rails 14 are arranged around the linear guide 5. The swing weights 12, 13 are connected to each other at a fixed distance from each other, in particular by a rigid connection 15, which can be formed, for example, by a linkage. Due to the rigid connection 15, the swing weights 12, 13 always have the same distance from each other. Via the pulse generator 6, a pulse is transmitted to the swing weight 12, so that the swing weight 12 is positioned at the outer diameter of the rotating body 2. The swing weight 13 is thus moved to a position in the direction of the drive shaft 4, where the spring element 7 between the swing weight 13 and the drive shaft 4 is again tensioned. For further movement, pulses are transmitted to the swing weight 13 by the pulse generator 6. In this case, the spring element 7 is relaxed.
