Description

Technical Field

[0001] The present invention relates to a drive device having a base body and at least one rotating unit, wherein the rotating unit is arranged on the base body in a manner at least rotatably supported, 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 pendulum weights, wherein the pendulum weights are arranged so as to be radially slidable relative to the drive shaft, wherein the pendulum weights are arranged in pairs, wherein the pendulum weights are arranged on mutually opposite sides of the drive shaft, and wherein the pendulum weights are connected to one another at a fixed distance from one another. Background Art

[0002] Drive systems are used in a wide range of applications, such as in vehicles and remotely controlled or autonomous vehicles. When operating land vehicles with driven wheels, tire contact with the road surface can pose risks, such as hydroplaning or icy roads. Furthermore, tire wear can occur due to the constant contact between the tires and the road surface.

[0003] For example, DE 102019126489 A1 discloses a drive device having a base body and at least two rotating units, wherein the rotating units are at least rotatably mounted on the base body, each of the rotating units having at least two rotating shafts driven in opposite directions of rotation. Each rotating shaft drives at least one rotating body, wherein the rotation planes of the rotating bodies of the rotating units are arranged parallel to one another. Each rotating body has at least one oscillating weight, each of which is radially displaceably supported relative to the rotating shaft. During one section of rotation, one oscillating weight is located in the region of the drive shaft, and a second oscillating weight is located in an unbalanced position. These oscillating weights can slide radially relative to the axis of rotation on the rotating body, resulting in an imbalance in one segment of a rotation and a balancing motion in another segment of a rotation. The imbalance should be oriented in the same direction for all rotating bodies and all rotating units, thereby generating a pulsation of the base body in one direction.

[0004] Due to the large forces acting, precise and robust control and generation of the pulses of the oscillating weight are crucial for the efficient functioning of the drive.

[0005] The object of the present invention is to provide a drive device of the aforementioned type in which a robust control of the pulses of the oscillating weight can be achieved in a simple manner.

[0006] This object is achieved with a drive device having the features of claim 1. Developments and advantageous embodiments are specified in the dependent claims. Summary of the Invention

[0007] In a drive device having a base body and at least one rotating unit, wherein the rotating unit is at least rotatably mounted on the base 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 pendulum weights, wherein the pendulum weights are arranged so as to be radially displaceable relative to the drive shaft, wherein the pendulum weights are arranged in pairs, wherein the pendulum weights are arranged on opposite sides of the drive shaft, and wherein the pendulum weights are connected to one another at a fixed distance from one another, it is essential for the present invention 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 radially relative to the drive shaft, the pulse generators are arranged on opposite sides of the drive shaft, at least one spring element is respectively arranged between the pulse generator and the drive shaft, the spring elements are each designed to deflect the corresponding pulse generator along the linear guide, the rotating unit has at least one guide plate for controlling the distance of the pulse generator from the drive shaft during rotation of the drive shaft, and the pulse generators are assigned to the pendulum weights in a pulse-transmitting manner.

[0008] The "base" may, in particular, be a flat baseplate. The rotating unit is received by the baseplate so as to be rotatable at least relative to the baseplate. For example, the rotating unit may also be received in a pivotable and rotatable manner. The "pivotable reception" may, in particular, be a universal suspension. For example, the baseplate may have an opening in which the rotating unit is received. Furthermore, the rotating unit is rotatably received in the opening of the baseplate. The drive device may include three or more, preferably four or more, rotating units. The rotating body may, in particular, be disk-shaped, for example, circular, as a rotating disk. A drive shaft may, in particular, be arranged at the center of the rotating body to drive the rotating body. The rotating body may be set into rotation by means of the drive shaft. The drive shaft may, for example, be driven by an electric motor or the like. Each rotating body has at least two oscillating weights, each of which is radially displaceably supported relative to the rotation axis. In particular, the oscillating weights may be two oscillating weights of identical shape and mass connected to one another at a fixed distance. During a portion of the rotating body's rotation, one oscillating weight is located on or in the region of the drive shaft, while the second oscillating weight is in an unbalanced position. In a balanced or approximately balanced state, the two oscillating weights, for example, are at the same distance from the drive axis. When using two oscillating weights connected to each other at a fixed distance from each other, the oscillating weights can each be at the same distance from the drive axis in a balanced or approximately balanced state, i.e., within a semicircle of rotation. The oscillating weights can, for example, be slidably supported on a guide element, such as a guide rail or a sliding rail, wherein the guide element is arranged radially from the axis of rotation on the rotating body. The oscillating weights can slide radially on the rotating body relative to the axis of rotation, thereby generating an imbalance within a circle segment of a revolution, i.e., within an angular segment of a revolution, while achieving a balanced or approximately balanced movement within another angular segment of the revolution. Preferably, the imbalance should be oriented in the same direction and with the same pulse excitation for all rotating bodies and all rotating units of the drive device. For example, the oscillating weights can also be arranged parallel to each other on both sides of the rotating body, and can slide synchronously and overlappingly. To bring the oscillating weights into at least an approximately balanced or unbalanced position, the rotating body has a pulse body. To guide the pulse generators, the rotating body has linear guides along which the pulse generators can slide in a radial direction relative to the drive shaft. The pulses are transmitted to the corresponding oscillating weights by the pulse generators, for example, by collision. By sliding along the linear guides, the spacing of the pulse generators from the drive shaft (and thus from the axis of rotation) is controlled, and the corresponding spring tension of the spring elements is also controlled. By controlling one pulse generator to a position farther from the axis of rotation within a rotational range (i.e., within the angular range of rotation) while the other pulse generator is positioned closer to the drive shaft, pulses can be transmitted in one direction, with corresponding pulse transmission to the oscillating weights.Starting from the drive shaft, the linear guide of the rotating body extends radially on opposite sides. For example, the linear guide can be constructed by a groove-shaped recess in the rotating body (especially in the rotating disk), wherein the pulse generator is guided in the linear guide in a manner that can slide in the radial direction. Therefore, the pulse generator can slide in the linear guide along the radius of the rotating disk. At least two pulse generators are assigned to the rotating body, wherein these pulse generators are arranged on radii on opposite sides of the drive shaft. Spring elements are respectively arranged between the pulse generator and the drive shaft. The spring elements can especially be compression springs. Here, the spring elements are arranged so that the pulse generator is pushed away in the radial direction by the drive shaft when the spring elements are relaxed (i.e., when the spring force is released). In order to bring the pulse generator close to the drive shaft, the spring element must be compressed and therefore the spring force must be applied. The rotating body is assigned at least one slotted disk for controlling the distance between the pulse generator and the drive shaft. In particular, the slotted disc can be oriented parallel to the guide body (i.e., in particular, parallel to the guide disc), wherein the plane defined by the guide body is arranged parallel to the plane defined by the slotted disc. The slotted disc has a slotted guide for the pulse generator. This slotted guide can, in particular, be formed by a guide opening into which a guide pin of the pulse generator can engage. The guide pin can, for example, be cylindrical and arranged perpendicular to the plane defined by the rotating disc (i.e., the rotating body). The rotating body is set into rotation relative to the slotted disc by the drive shaft, causing the guide pin of the pulse generator to move along the inner edge of the guide opening. Depending on the shape of the guide opening, the pulse generator moves along the linear guide during the rotation of the rotating body. To achieve directional pulses of the drive device and transmit pulses from the pulse generator to the oscillating weight, one pulse generator is moved closer to the drive shaft during a section of rotation, wherein the spring element is compressed. The other pulse generator, which is arranged opposite the drive shaft, is then located farther away from the drive shaft. During one rotational segment, the transition occurs as follows: the pulse generator farther from the drive shaft moves through a guide opening in the guide plate toward the drive shaft, requiring the application of spring force to compress the spring element. At essentially the same time, the other pulse generator closer to the drive shaft moves away from the drive shaft through the guide opening. This causes a sudden release of the spring force of the spring element, causing the pulse generator to suddenly move away from the drive shaft due to the centrifugal force acting during rotation and supported by the spring element. The pulse generator's pulse is transmitted, for example, by a collision, to radially displaceably supported oscillating weights. The pulse generator's pulse can be transmitted synchronously and overlappingly to the two oscillating weights arranged on either side of the rotating body. For example, when the spring element relaxes, the pulse generator's pulse can be transmitted to the first oscillating weight by a collision, causing it to accelerate to a position at the outer radius of the rotating body. A second oscillating weight, connected to the first oscillating weight at a fixed distance from the first oscillating weight, is then moved closer to the drive shaft.The spring elements of the pulse generator dampen the oscillating weights before they reach their respective end positions. This allows for a directional pulse of the entire drive, which, when the corresponding pulse is transmitted, causes the drive to move. To this end, the drive can, in particular, have multiple rotating units that can generate pulses in a controlled manner in parallel. The pulse direction can be controlled by rotating the gate disk.

[0009] In one embodiment of the present invention, the rotating body is disk-shaped, the rotating body and the at least one gate plate are arranged parallel to one another, and the drive shaft of the rotating body is arranged perpendicular to the plane defined by the rotating body and the at least one gate plate. The rotating body is disk-shaped, preferably circular. The rotating body and the gate plate can be arranged parallel to one another so that a guide pin of the pulse generator, which extends perpendicularly to the plane defined by the gate plate and the rotating body, can engage in a guide opening of the gate plate. When the rotating body rotates relative to the gate plate, the guide pin is guided along the inner edge of the guide opening of the gate plate, so that the corresponding distance of the pulse generator from the drive shaft, and thus indirectly the corresponding distance of the oscillating weight from the drive shaft, can be controlled by the gate plate during rotation.

[0010] In one embodiment of the present invention, the linear guide is configured as a guide groove. The linear guide of the rotating body can be configured as a groove-shaped recess. The groove-shaped recess extends radially from the drive shaft in the rotating body, that is, in the direction of the radius on two opposite sides of the drive shaft.

[0011] In one embodiment of the present invention, the rotating body is rotatably supported about the rotation axis of the drive shaft independently of the gate plate. The rotating body is driven by the drive shaft about its rotation axis, wherein the rotating body moves independently of the at least one gate plate. The independent rotation of the rotating body relative to the gate plate enables pulse control.

[0012] In one embodiment of the present invention, the guide plate has a guide opening, and the inner edge of the guide opening is configured to control the movement of the pulse generator along the linear guide. A guide pin of the pulse generator engages in the guide opening and moves along the inner edge of the guide opening while the rotating body rotates relative to the guide plate. The guide pin is pressed against the inner edge of the guide opening by the spring force of the spring element. Thus, 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 can, for example, have a friction-reducing coating. In particular, the guide opening can be configured such that the spring element is strongly compressed only over one rotational section (i.e., within one angular section) and less strongly compressed over a subsequent rotational section of the same length (i.e., within an angular section of rotation of the same size). This ensures that the force required during rotation remains constant. The spring force required to compress a spring element increases until the spring element is fully compressed.

[0013] In one embodiment of the present invention, the distance between the inner edge of the guide opening and the drive shaft varies along the inner edge, and this distance is selected based on the spring force of the spring element. In particular, the guide opening can be designed so that when a relaxed spring element is re-tensioned due to the application of spring force, it is initially compressed strongly in a circular segment, but is less compressed in a subsequent circular segment of the same length. This ensures that the force required to compress the spring element due to the drive shaft remains constant during rotation. The spring force required to compress the spring element increases until the spring element is fully compressed. Therefore, in the first segment, the guide opening has a steeper slope relative to the drive shaft, resulting in a stronger compression of the spring element over a smaller angular segment of rotation. Later in the segment, the slope of the outer edge of the guide opening gradually flattens, resulting in a less intense compression of the spring element over the same angular segment as in the first region. This results in a constant force requirement for compressing the spring element during rotation.

[0014] In one embodiment of the present invention, each pulse generator has at least one guide pin, and the guide pin engages in a guide opening of the gate disk. Each pulse generator has at least one guide pin, which is arranged perpendicular to the plane spanned by the rotating body or the plane spanned by the guide groove. Due to the perpendicular arrangement to the rotating body, the guide pin can engage in a guide opening of the gate disk arranged parallel to the rotating body.

[0015] In one embodiment of the present invention, the shape of the guide opening is essentially formed by two essentially semicircular surfaces, wherein the first essentially semicircular surface has a larger radius than the second essentially semicircular surface. It is provided that, during rotation of the rotating body, a pulse generator, and therefore an oscillating weight, is initially located farther from the drive shaft and then moved closer to the drive shaft. Thus, the two essentially semicircular surfaces serve as the shape of the guide opening of the gate plate. The essentially semicircular surfaces forming the guide opening of the gate plate can also be a hyperbola, an ellipse, or the like. If the guide pin of the pulse generator moves along the inner edge of the larger essentially semicircular surface, the pulse generator moves further away from the rotation axis. In the section where the guide opening is defined by the smaller essentially semicircular surface, the pulse generator moves along a linear guide toward the drive shaft. The diameters of the two essentially semicircular surfaces are arranged essentially opposite each other, in particular, so as to lie on a line. Accordingly, the center point or focus of the essentially semicircular surface, i.e., the point around which the corresponding radius of the semicircle or ellipse is formed, is also located on this line, which can also have a non-linear shape. The axis of rotation of the drive shaft can also lie on this line. The centers of the circles are arranged staggered on this line. By arranging the center points or focal points and selecting the corresponding radii, the position of the pulse generator can be adjusted during the rotation of the rotating body. The larger the radius of the semicircle or ellipse, the further the oscillating weight is arranged from the drive shaft.

[0016] In one embodiment of the present invention, the centers of the substantially semicircular surfaces are arranged on one and the same line, and the centers are arranged offset from one another on this line. By arranging the centers of the semicircles or foci of the ellipses on one line and offsetting one another, a transition in movement of the pulse generator from a position near the drive shaft to a position remote from the drive shaft can be achieved.

[0017] In one embodiment of the present invention, the radius of the larger, first, substantially semicircular surface is significantly larger than the radius of the smaller, second, 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 when it is farther from the drive shaft than when it is 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 corresponding spring tension between the pulse generator and the drive shaft is predetermined by the radius of the semicircular surface.

[0018] In a preferred embodiment of the present invention, the rotary unit has two sliding plates arranged parallel to the rotating body on both sides, with their guide openings arranged to overlap. The pulse generator preferably has a guide pin that protrudes from both sides of the plane spanned by the rotating body and engages on both sides in the guide openings of the sliding plates arranged there. The guide openings of the sliding plates are arranged to overlap, so that the guide pin is guided equally by both sliding plates. This results in significantly more stable guidance of the pulse generator.

[0019] In one embodiment of the present invention, each rotary unit is associated with a second rotary unit having a drive shaft driven in opposite directions of rotation. To achieve the most stable possible operation of the drive device, the rotary units are configured in pairs, with the directions of rotation being opposite. This results in a more stable operation of the drive device.

[0020] In one embodiment of the present invention, at least two oscillating weights are each arranged to be supported in a sliding manner on a guide element. For example, a guide element, in particular a sliding track, can be arranged around the linear guide of the pulse generator so that the oscillating weights connected to each other at a fixed distance from each other can be slidably arranged on this guide element in a manner parallel to the pulse generator. For support, the guide element can also have ball bearings, sliding bearings, etc. The oscillating weights can be struck by the pulse generator or the guide pin of the pulse generator, thereby transmitting the pulse from the pulse generator to the oscillating weights. The connection between the oscillating weights at a fixed distance from each other can be constructed, for example, by a connecting rod. For example, this connection at a fixed distance from each other can be constructed to be rigid. In particular, the rigid connection can always provide the same distance between the oscillating weights. The pulse transmitted to the first oscillating weight is thus directly transmitted to the second oscillating weight.

[0021] In an extension of the present invention, the rotating body has a plurality of sliding elements, and the guide elements extend radially on both sides of the drive shaft. The rotating body can have a plurality of swinging weights. The swinging weights are connected to each other in pairs at a fixed distance from each other, for example by connecting rods. Each two swinging weights can be arranged slidably on a sliding element. In this case, the guide elements extend radially from both sides of the drive shaft. Preferably, the guide elements are arranged equidistant from each other, in particular, the angles between adjacent guide elements are the same. While the rotating body rotates relative to the guide plate, the pulse generator moves so that it hits the swinging weights in turn. Thus, pulses can be transmitted to the plurality of swinging weights by the two rotating pulse generators. The guide elements can also be arranged, in particular superimposed, on both sides of the rotating body.

[0022] Furthermore, the rotating body can have multiple linear guides that extend radially on both sides of the drive shaft. In particular, the linear guides can be arranged evenly distributed over the rotating body. The angles between two adjacent linear guides can be identical. Each of the two oscillating weights or two oscillating weight pairs (one oscillating weight pair on each side of the rotating body) arranged on one side of the rotating body can be assigned a linear guide having two pulse generators.

[0023] In one embodiment of the present invention, the pulse generator is arranged radially between the drive shaft and the corresponding oscillating weight. This radial arrangement of the pulse generator between the drive shaft and the oscillating weight enables pulses to be transmitted from the pulse generator, or in other words, its guide pin, to the oscillating weight. For example, when the pulse generator is moved away from the drive shaft, i.e., when the corresponding spring element is relaxed, the oscillating weight can be moved to a position at the outer radius of the rotating body. Therefore, by arranging the pulse generator between the drive shaft and the oscillating weight, the oscillating weight can receive pulses from the pulse generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] exist Figure 1, shows a rotating unit 1 having a disk-shaped rotating body 2 and two sliding plate disks 3 arranged parallel to the rotating body 2. The rotating body 2 is set into rotation by a drive shaft 4. The rotating body 2 has a linear guide 5 in which a pulse generator 6 is guided. The linear guide 5 is configured as a groove-shaped recess in the rotating body 2 and extends radially on opposite sides of the drive shaft 4. A spring element 7 is arranged between the pulse generator 6 and the drive shaft 4. The spring element 7 can be configured as a compression spring element. The spring element 7 is configured such that the pulse generator 6 is pushed away from the drive shaft 4 along the linear guide 5 by the spring element 7. The sliding plate disks 3 are arranged parallel to the rotating body 2 on both sides of the rotating body 2. The rotating body 2 is rotated relative to the sliding plate disks 3 by the drive shaft 4. The pulse generator 6 each has a guide pin 9 arranged perpendicular to the plane of rotation, that is, perpendicular to the plane spanned by the rotating body 2. The guide pin 9 engages in the guide opening 8 of the gate disk 3 and moves along the inner edge of the guide opening 8 during the rotation of the rotating body 2. The guide pin 9 is pressed against the inner edge of the guide opening 8 by the spring force of the spring element 7. The distance between the pulse generator 6 and the drive shaft 4 is controlled along the linear guide 5 via the guide opening 8 of the gate disk 3. Thus, one pulse generator can be moved closer to the drive shaft 4, while the other pulse generator is moved further away from the drive shaft 4 essentially simultaneously, supported by centrifugal force and the relaxation of the spring force of the spring element 7. This allows the generation of directional pulses.

[0030] exist Figure 2 In the side view, the Figure 1 Rotating unit 1 . Identical components are provided with the same reference numerals. The shape of the guide opening 8 of the guide plate 3 essentially consists of the areas of two semicircles 10 , 11 . The larger section 10 moves the pulse generator 6 further away from the drive shaft 4 . The smaller section 11 moves the respective pulse generator 6 further along the linear guide 5 toward the drive shaft 4 during the rotation of the rotating body 2 .

[0031] exist Figure 3 In the other side view, the Figure 1 The rotary unit 1 is provided with the same reference numerals. The guide plates 3 can be adjusted to be rotatable parallel to one another, in particular so that the guide openings 8 remain overlapping, in order to control the direction of the directional pulse.

[0032] exist Figure 4 In the figure, it is shown that Figure 1Rotating unit 1. Rotating body 2 has pendulum weights 12, 13, which are supported on guide elements, here, slide rails 14. Slide rails 14 are arranged around linear guide 5. Pendulum 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 constructed, for example, by connecting rods). Due to rigid connection 15, pendulum weights 12, 13 always have the same distance from each other. Pulses are transmitted to pendulum weight 12 by pulse generator 6, so that this pendulum weight is now in a position at the outer radius of rotating body 2. Accordingly, pendulum weight 13 has moved in the direction of drive shaft 4 to a position whereby spring element 7 between pendulum weight 13 and drive shaft 4 is tensioned again. During further movement, pulses will now be transmitted to pendulum weight 13 by pulse generator 6. In this process, spring element 7 will relax.
