Description

Drive device with a base body and with at least two rotation units

The invention relates to a drive device with a base body and with at least two rotation units.

Drive devices are used in a large number of application areas, for example for remote-controlled or autonomously driving vehicles. When operating conventional land vehicles with drive wheels, hazards can arise due to aquaplaning, ice-covered roadways or the like when the tires come into contact with the roadway. In addition, there may be signs of wear and tear on the tires due to the contact between the tires and the road.

The invention is based on the object of proposing a drive device in which there is as little contact as possible between the roadway and the driven vehicle.

This object is achieved with a drive device with the features of claim 1. Further developments and advantageous refinements are given in the subclaims.

According to the invention, a drive device is provided with a base body and with at least two rotation units, the rotation units being arranged at least rotatably on the base plate The rotation units each have at least two rotation shafts driven in opposite directions of rotation, each rotation shaft driving at least one rotation body, the planes of rotation of the rotation bodies of a rotation unit being arranged parallel to one another, each rotation body having at least one swing weight and the swing weights each being radial to the Rotary shaft are slidably mounted.

The drive device has a base body which is designed to accommodate the rotation units. The base body can in particular be a flat base plate. The rotation units are at least rotatably received by the base body in relation to the base body. For example, the rotation units can also be accommodated in a pivotable and rotatable manner. The pivotable receptacle can in particular be a cardanic 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 in the base plate. The drive device preferably has three or more, preferably four or more, rotation units. The rotary units each have at least two rotary bodies, a rotary shaft being assigned to each rotary body. With four rotation units, eight rotation bodies are provided, for example. The rotating bodies can be designed, for example, in the form of rotating arms, rotating disks or also guide rails. The centers of mass of the rotating bodies are each connected to the assigned rotating shaft in a manner that transmits drive energy. The rotating shafts of a rotating unit are driven in opposite directions, so that the rotating bodies rotate in mutually opposite directions. The planes of rotation, that is to say the planes each spanned by the rotation of a body of revolution, of the body of revolution of a unit of revolution, are arranged parallel to one another. In the basic position For example, the respective planes of rotation can be arranged perpendicular to the plane spanned by the base plate. Due to the rotatable and pivotable mounting of the rotation units, the rotation planes can be aligned accordingly. Each rotating body has at least one flywheel, the flyweights each being mounted such that they can be displaced radially with respect to the rotating shaft. For example, a body of revolution can also have two rigidly connected flyweights of the same shape and mass. In one section of the rotation there is a flyweight on or in the area of the drive shaft and the second flyweight is in an unbalanced position. When balanced, both flyweights have the same distance from the drive shaft. The flyweights can, for example, be accommodated displaceably on guide rails or slide rails, the guide rails being arranged on the rotation bodies starting radially from the axis of rotation. In an alternative embodiment, the rotating bodies are designed as guide rails on which the flyweights can be mounted in a sliding and / or floating manner. Here, slide rails can also be designed in such a way that the flyweights are mounted in a floating manner on the slide rail. For example, magnetic levitation technology can be used here. The flyweights can be shifted on the rotating bodies radially to the axis of rotation in such a way that there is an imbalance in a circle segment of the same revolution and that a balanced movement is made possible in a further circle segment of one revolution. Preferably, the unbalances in all rotating bodies and all rotating units are directed in the same direction and clocked in the same way, so that a pulse of the base body results in one direction. For example, the flyweights can be in a non-balanced position in a semicircle of the orbit and in a balanced position in the second semicircle of the rotation. When balanced, the center of gravity of the flyweight can coincide with the drive shaft. When using two rigidly connected flyweights, the flyweights in the balanced state, that is, in a semicircle of rotation, can each have the same distance from the drive axis. In the case of a single swing weight movably mounted on a guide rail, the swing weight can also slide during a rotation from a maximally deflected position, i.e. from a position on the guide rail that is maximally spaced apart from the axis of rotation to the other maximally deflected position on the guide rail, without being in the balanced position To remain in position on the axis of rotation. By using several rotating bodies with swing weights, the stability of the directed impulse can be increased. With a corresponding pulse transmission, the drive device can move in the direction of the pulse. A targeted shifting of the swing weights and tilting and twisting of the planes of rotation of the rotating bodies enables the drive device to move without permanent contact with the road surface being necessary for this. For example, a drive device according to the invention could also be used in satellites, space probes or the like.

In a further development of the invention, the rotating bodies are each assigned at least one magnet and / or at least one magnetizable body, at least one magnet and / or one magnetizable body is arranged on the rotating body in the area of the axis of rotation and at least one magnet or one magnetizable body is on each arranged outer circumference of rotation of the rotating body. At least one magnet and / or a magnetizable body in the area of the axis of rotation and a magnet and / or a magnetizable body in the area of the circumference of rotation are each arranged on the rotating bodies. For example, a rotary body can be formed by a circular rotary disk, the axis of rotation and thus the rotary shaft being arranged in the area of the center of the circle. In the area the center of the circle and on the outer circumference of the circular

A magnet can be arranged in each case of rotation, a flyweight being mounted so that it can be displaced radially on the flywheel that the flyweight can be displaced between the two magnet positions. The swing weights also have magnetic or magnetizable properties. Due to the arranged magnetizable or magnetic bodies on the flywheel, the flyweights can thus be attracted so that the

Flyweights can be moved from a position close to or on the axis of rotation to a position on the outer edge of the flywheel and can be fixed at these two positions. Thus, the flyweights can be held in an unbalanced position in half a revolution of the rotation and in a balanced position with the focus on the center of the circle, i.e. the drive shaft, in the second half of the rotation. Furthermore, a swing weight can only be shifted between the maximum deflections and fixed at these positions without being fixed in the area of the axis of rotation. Thus, a targeted control of balanced and unbalanced states of the rotational body is possible.

In a further development of the invention, the flyweights have magnetic and / or magnetizable properties. The flyweights can themselves have a ferromagnet or an electromagnet or consist at least in sections of magnetizable material so that an attraction or repulsion can act between a magnet or a magnetizable body and a flywheel. As a result of the forces of attraction and repulsion, the flyweights can be brought into the corresponding positions and / or fixed there by magnets or magnetizable bodies that are appropriately positioned on the flywheels. In particular, it can be, for example, with the swing weights and the magnetic bodies are electromagnets. Targeted control of the electromagnets can achieve a targeted attraction or repulsion between the flyweights and the magnetic bodies. For example, the movement of a swing weight from the balanced position in the area of the rotary shaft, in particular on the rotary shaft, during the rotary movement into the unbalanced position in the area of the outer radius of the guide rail can be supported. For example, an electromagnet arranged on the rotating shaft can be polarized in such a way that the flyweight is repelled, while an electromagnet arranged on the outer radius is polarized in such a way that the flyweight is attracted. For this purpose, the flywheel can also have permanent magnetic properties. A reverse movement of the flyweight can be achieved by reversing the polarity of the electromagnets.

In a further development of the invention, the flyweights have at least one electromagnet and / or one permanent magnet. The flyweights can have an electromagnet and / or a permanent magnet, and the rotating bodies accordingly have magnetizable bodies, so that a magnetic interaction between the magnets of the flyweights and the magnetizable bodies of the rotating bodies can be established. Thus the swing weights can be fixed in the desired position. By using electromagnets, a possibility is created in a simple manner to hold the flyweights in position at the desired times or to bring the flyweights into position through the repulsion and attraction and the resulting impulse. In addition, for example, by a repulsion between the flyweight and the outer electromagnet, the radially outwardly directed pulse of the flywheel before reaching the End position can be dampened. For this purpose, the polarity of the electromagnet can be selected to be timed accordingly.

In a further development of the invention, at least one guide rail is assigned to each of the rotating bodies, the guide rails are arranged radially to the respective rotation shaft and the flyweights are slidably mounted on the guide rails. A guide rail, for example in the form of a slide rail, on which the flyweights are slidably mounted, is arranged on the rotating bodies for each swing weight. Two flyweights, which are rigidly connected at a distance from one another, can also be slidably mounted on a slide rail. The slide rails are here arranged radially to the axis of rotation of the respective rotating body. A low-friction shifting of the flyweights between the axis of rotation and the outer circumference of the rotational movement is possible on the slide rails, for example slide bearings, ball bearings, roller bearings, magnetic levitation technology or the like can be used for this purpose. In this way, balanced and unbalanced states can be set reliably even with high forces acting. Several flyweights can also be arranged on a slide rail.

In one embodiment of the invention, the rotating bodies are designed as guide rails, the guide rails are arranged radially to the respective rotation shaft and the flyweights are slidably mounted on the guide rails. The guide rails can form the rotating bodies, the guide rails each having a direct connection to the rotating shafts that transmits drive energy. Correspondingly, the magnets for controlling the flyweights can be arranged directly on the guide rails.

In a further development of the invention, a gear for radial displacement is assigned to the flyweights. The swing weights can be over Transmission devices or be moved via cables or the like.

In a further development of the invention, each swing weight is assigned at least one spring element for damping the movement of the swing weight in the area of the maximum deflected position of the swing weight. To generate a pulse in one direction, the flyweights of the rotation units are shifted in a section of a revolution into an unbalanced position, in particular in a maximally deflected position, that is to say at a maximum distance from the drive shaft. In particular, when the rotating body is driven by the rotating shaft, a slidingly mounted flywheel can be moved into an outer position in the area of the outer radius of the rotating body due to the acting centrifugal force. At least one spring element is assigned to at least one flywheel in order to dampen the high forces or impulses that act when the end position is reached. For example, an assigned spring element can be a compression spring, a rubber damping element, a gas pressure spring or the like, which is compressed when the maximum deflection of the swing weight is reached, so that the spring force counteracts the centrifugal force acting on the swing weight and thus the swing weight before reaching the maximum deflection is braked. The spring force counteracting the centrifugal force prevents damage to rotating bodies due to the high centrifugal forces acting on the flyweights when the end position is reached.

In a further development of the invention, at least one spring element is designed as a compression spring, the compression spring being compressed when the maximum deflected position of the swing weight is reached. The spring elements assigned to the flyweights are preferably designed as compression springs. The compression springs are arranged so that this on reaching the outer end position of the respective swing weight are compressed so that the spring force of the spring element counteracts the centrifugal force acting on the swing weight due to the rotation of the rotating body. As a result, the movement of the swing weight caused by the centrifugal force during rotation is dampened in the area of maximum deflection in order to prevent damage.

In a further development of the invention, at least one spring element is brought into contact on one side with the rotary shafts driving the rotary bodies. The spring force for damping the movement of the swing weight can be applied by arranging a spring element between the swing weight or a component connected to the swing weight and the rotary shaft. For example, a rotary body can be designed as a rotary arm on which a flyweight is arranged in a sliding manner. During a rotation of the rotating body, the swing weight can be arranged in a section of the rotational movement in an unbalanced state, that is to say between the rotating shafts and the outer ends of the rotating arm. In a further section of the rotational movement, the swing weight is brought into a balanced state, the center of mass of the swing weight coinciding with the center of the rotating shaft. Furthermore, a flyweight can also be moved between the positions of maximum deflection without being fixed in the area of the rotary shaft. The swing weight is thus shifted back and forth between the outer ends of the rotating arm to generate a directed impulse. The rotary arm can have two catching elements which each extend to one side of the rotary shaft, in particular parallel to a guide rail on which the flywheel is slidably mounted. The collecting elements are slidably mounted, for example on a slide rail. A catch element has a catch side against which the swing weight is displaced, the swing weight being the Receiving side cannot pass. When the swing weight hits the catching side, the catching element is moved along with the swing weight in the direction of the outer end of the rotating arm. Furthermore, the catching element has a side guided around the rotary shaft, so that the maximum deflection of the swing weight along the rotary arm is predetermined by the longitudinal extension of the catching element. The spring element in the form of a compression spring is arranged between the side guided around the rotary shafts and the rotary shaft. When the centrifugal force now moves the swing weight in the direction of one end of the rotating arm, i.e. when the swing weight approaches its maximum deflection and thus its maximum radius of rotation, the spring element is compressed between the end of the receiving element facing the rotating shaft and the rotating shaft, so that the The spring force of the spring element counteracts the centrifugal force. The movement of the swing weight is slowed down before reaching its maximum deflection, i.e. before reaching the maximum distance to the rotating shaft, and thus the acting force is dampened. Correspondingly, the second side of the rotating arm, which, starting from the rotating shafts, extends in the direction opposite to the first side, also has a collecting element. The spring element of the catching element of the second side of the rotary arm is correspondingly arranged on the side of the rotary shaft opposite the spring element of the first side of the rotary arm. The spring element of a catching device is thus arranged on the opposite side of the rotating arm. Thus, the impact of the swing weight is dampened on both sides of the rotating arm when its maximum rotation radius is reached.

In a further embodiment, two swing weighted units that are rigidly connected to one another are arranged to slide on a slide rail of a rotating body, in particular a rotating arm. Here there is a flyweight on one side of the rotating shaft as seen from the Rotation arm and a swing weight on the other side of the rotation arm. Spring elements are arranged on both sides of the rotary shafts. When a first swing weight approaches its maximum deflection, that is to say its maximum rotation radius, the spring element is compressed between the rotating shafts and the second swing weight, which is not in maximum deflection but is closer to the rotating shaft. When the second swing weight approaches the maximum deflection, that is to say the maximum distance from the rotating shafts, the first swing weight is accordingly brought closer to the rotating shafts. Due to the rigid connection between the two swing weights, the action of the spring force dampens the movement of the swing weight approaching the maximum deflection. Correspondingly, when the rotary unit continues to move, the centrifugal force and the spring force of the spring element pushing apart again move the flywheel which is approaching the rotary shaft into the maximally deflected position. For this purpose, at least one swing weight can be fixed in the area of the rotary shaft or in the maximally deflected position and the fixing can be released in a timed manner in order to obtain a targeted impulse.

In a further development of the invention, each of the flyweights is assigned at least one locking device for the simultaneous locking of the radially displaceable flyweights. A locking device is assigned to each of the swing weights, with which the swing weights can be fixed, for example, in the balanced or unbalanced position. In this way, the swing weights can be held in the required position even with high forces.

In one embodiment of the invention, at least one rotating body is designed as a rotating arm and / or at least one rotating body is designed as a rotating disk. The rotating bodies of a rotating unit can for example be designed as rotating arms or rotating disks. Rotary disks are preferably circular so that, for example, slide rails for the displaceable mounting of the flyweights can be arranged on them. The rotating bodies can also be elongated, planar rotating arms, the center of gravity being given by the axis of rotation, that is to say by the rotating shaft. The magnets can be arranged on the rotating bodies, in particular in the area of the drive shafts and in the outer area of the rotation circumference.

In one embodiment of the invention, the rotary shafts of a rotary unit are connected to a cardan shaft for driving purposes. The rotary shafts for driving the rotary bodies can be connected to a cardan shaft in order to enable the rotary shafts of the various rotary units to be driven with a central drive device.

In a further development of the invention, each rotation unit has a vacuum bell, the vacuum bell surrounds a vacuum and the rotating shafts, the rotating bodies and the flyweights are arranged at least in sections in the vacuum bell. Each rotation unit can have a vacuum bell jar, with a vacuum atmosphere, that is to say an atmosphere with reduced air pressure, prevailing in the vacuum bell jar. The rotating bodies, the flyweights and the rotating shafts are arranged inside the vacuum bell jar of a rotating unit. The arrangement of the rotating components in a vacuum enables very energy-efficient operation, since no energy is lost unused in the form of air friction.

In a further development of the invention, only the flyweights and the magnets are made of magnetic or magnetizable material. To influence the control of the swing weights by others To prevent magnetic or magnetizable bodies, the remaining components of the drive device consist of non-magnetic and non-magnetizable material such as plastic. This ensures that the flyweights can be influenced in a targeted manner without, for example, flyweights having electromagnets being fixed in undesired positions through interaction with magnetizable components, their movement being impaired or being set in motion in an undesired manner.

Another aspect of the invention relates to a method for operating a drive device with a base body and with at least two rotation units, the rotation units being at least pivotably mounted on the base body, the rotation units each having at least two rotation shafts driven in opposite directions of rotation, each rotation shaft at least drives a rotating body, the planes of rotation of the rotating bodies of a rotating unit being arranged parallel to one another, wherein each rotating body has at least one flywheel, and the flyweights are each mounted so that they can be displaced radially to the rotating shaft Rotational movement can be brought into a balanced position and that the swing weights in another section of the same rotation are in an unbalanced P can be brought into position. To operate the drive device, the rotating bodies of the rotating units are set in rotation, planes of rotation of the rotating bodies of a rotating unit being arranged parallel to one another and the directions of rotation of the two rotating bodies being aligned opposite to one another. The drive device preferably has at least three or more rotation units, particularly preferably at least four rotation units. The rotation units are at least pivotable, preferably rotatable and pivotable, on the base body, in particular on the base plate of the Drive device added. The rotation units are preferably rotated and pivoted parallel to one another in such a way that the planes of rotation of all the rotating bodies are arranged parallel to one another. For the drive, the flyweights, which are mounted radially displaceably to the rotating shafts of the rotating bodies, are moved outward in a segment of the rotational movement in the radial direction, while the flyweights are moved in another segment of the rotational movement in the direction of the rotating shaft. Shifting the swing weights results in a rotation that is unbalanced in sections. The imbalance results from the shifting of the flyweights in one section of the rotation into an outer, unbalanced, unbalanced position, while the flyweights in another section of the same revolution are shifted into a balanced, i.e. balanced position relative to the center of gravity of the rotating body, i.e. on the rotating shaft become. Due to the parallel alignment of the planes of rotation and the simultaneous shifting of the swing weights into an unbalanced position in all rotation units, an impulse in one direction is to be expected, so that a movement of the drive device in the impulse direction is possible with a corresponding impulse transmission. In particular, all flyweights are in a section of a revolution in an unbalanced position and in a further section, in particular in a semicircle, in a balanced position on the axis of rotation. Furthermore, a flyweight can also be moved between the positions of maximum deflection without being fixed in the area of the rotary shaft. The shifting of the flyweights from the balanced to the unbalanced position and back can be done by controlling the magnetic components. For example, the flywheels can have electromagnets, the flyweights being designed to be magnetizable. When the electromagnet is deactivated, the flyweights are shifted outward in the radial direction by the rotation of the rotating body due to the acting centrifugal force. The movement directed radially outwards can also be used of a flywheel are supported by corresponding polarized electromagnets on the outer circumference and on the axis, in that the flywheel is sucked in by the outer electromagnet and repelled by the electromagnet on the axis. By activating an electromagnet in the area of the axis of rotation or by setting the corresponding polarity on the axis and the outer electromagnet, the flyweights can be magnetically attracted or repelled and thus brought into the balanced position. Through the targeted control of the electromagnets in all rotation units, it is possible to control the pulse direction of the drive device. It can also be slidably mounted on a rotation body two rigidly connected flyweights of the same mass and shape. In the balanced state, both flyweights are at the same distance from the rotating shaft. In the unbalanced state, for example, a flyweight can be located on the rotary shaft and a flyweight is at a distance from the axis of rotation, that is, it is maximally deflected.

In a further development of the invention, the flyweights are brought into the desired positions by the arranged magnets and are fixed there at least for a short time. Due to the arranged magnets or magnetizable bodies, the flyweights can be brought into the desired position, for example from the unbalanced to the balanced position. In the balanced position in the area of the axis of rotation, the flywheels can be fixed, for example by magnets, and by canceling the interaction, the flyweights can be moved back into the unbalanced position, for example due to the acting centrifugal force.

In one embodiment of the invention, the flyweights are brought into the desired position by at least one gear. By Transmission devices, the flyweights can be designed to be movable, so that the flyweights can be moved into balanced or unbalanced positions at the desired times.

The invention is explained in more detail below using an exemplary embodiment shown in the drawing. The schematic representations show in detail:

In FIG. 1, a base body 1, which is designed as a flat base plate, is shown with four rotation units 2-5. The rotation units 2-5 are each received in a rotatable and pivotable manner in openings 6 of the base body 1. In particular, the rotation units 2-5 can be gimbaled to the base plate 1.

FIG. 2 shows a rotation unit 2 with two rotation shafts 7, 8 driven in opposite directions of rotation to one another. Rotary bodies 9, 10 are arranged on the rotary shafts 7, 8 and are set in rotation by the rotary shafts 7, 8 at their center of mass. The rotating bodies 9, 10 have magnets 11-14, which are received on the outer circumference of the rotating bodies. On the rotating bodies 9, 10 slide rails 15, 16 are arranged, on which flyweights 17, 18 are mounted so as to be radially displaceable relative to the rotating shafts 7, 8. The flyweights consist of a magnetizable material or have magnetizable material, so that the flyweights 17, 18 can be drawn to the outer circumference of the rotating bodies 9, 10 by the magnets 11-14 through the magnetic attraction force, or can be fixed here . A targeted control of the flyweights 17, 18 in a balanced or an unbalanced position can thus be achieved. A cardan shaft 19, for example, can be provided to drive the rotary shafts 7, 8.

FIG. 3 shows a detail of the side view of the slide rails 15, 16 of the rotary bodies 9, 10 of a rotary unit 2-5. In this case, the slide rails are arranged at a 90 ° angle to one another. The flyweights are fixed by magnets 20 in the area of the rotating shafts 7, 8 in such a way that the center of mass of the respective flywheel 17, 18 coincides with the center of mass of the respective rotating body 9, 10 and the axis of rotation. This results in a balanced position of the swing weights, so that in this position there is a concentricity of the rotating body 9 or 10.

In FIG. 4, a rotation unit 2-5 according to FIG. 3 is shown in an unbalanced state. The flyweights 17, 18 are held by magnets 11-14 in an outer position approximated to the circumference of the rotating body 9, 10, so that an imbalance and thus an impulse in the direction of the imbalance results in this section. The position of the rotating bodies 9, 10 rotating in opposite directions is shown as a sketch at different times.

In Figure 5, a slide rail 15 with a swing weight 10 is shown in the balanced state. In the area of the rotating shaft 7, electromagnets 20 are arranged, by means of which the flywheel 17 can be held in the area of the rotating shafts 7, that is to say in the balanced state.

In FIG. 6, a slide rail 15 according to FIG. 5 is shown. The magnets 11, 12 enable the flyweight 17 to be fixed in the outer regions of the rotating body 9, that is to say in the unbalanced state.

In FIG. 7, the rotary shafts 7, 8, which are driven by a cardan shaft 19, are shown inside a vacuum bell jar 21. Inside the vacuum bell jar 21 there is an atmosphere with reduced pressure, in particular a vacuum atmosphere. The air friction within the vacuum bell jar 21 is reduced by the vacuum atmosphere, so that a very low-friction and thus energy-efficient operation of the rotary shafts 7, 8 and the cardan shaft 19 is made possible. In FIG. 8, a rotating body 9 designed as a rotating arm is shown, on which a flyweight 17 is arranged in a sliding manner. The flyweight 17 is assigned catching elements 22, 23 which are provided to dampen the movement of the flywheel when the maximum deflection is reached, that is, when the maximum distance from the rotary shaft 7 is reached. The rotary arm 9 can have two collecting elements 22, 23, which each extend to one side of the rotary shaft 7, in particular parallel to a slide rail 15 on which the flywheel 17 is slidably mounted. The collecting elements 22, 23 are sliding and / or floating, for example mounted on a slide rail 15. In particular, a collecting element 22, 23 can be rectangular and have two long sides and two short sides. A short side of a collecting element 22, 23 is designed as a collecting side 24, 25, a swing weight 17 not being able to pass through the collecting side 24, 25. The collecting side 24, 25 can be arranged, for example, perpendicular to the longitudinal extension of the rotating arm or to the longitudinal extension of the slide rail 15. Furthermore, a catching element 22, 23 has a side 26, 27 guided around the rotary shaft 7, so that the maximum deflection of the flywheel 17 along the rotary arm 9 is predetermined by the longitudinal extension of the catching element 22, 23. A spring element 30, 31 in the form of a compression spring is arranged between the side 26, 27 guided around the rotary shaft and the rotary shaft 7. The swing weight 17 runs onto the collecting side 24, 25 of the collecting element 22, 23, the collecting element 22, 23 being moved along with the swing weight 17. Here, the spring element 30, 31 is compressed between the rotary shaft 7 and the end 26, 27 guided around the rotary shafts, so that the spring force of the spring element 30, 31 counteracts the centrifugal force acting on the flywheel 17. As a result, the movement of the flyweight 17 is braked shortly before reaching the maximum deflection. In Fig. 9 a body of revolution 9 with flyweights 17, 18 is shown. The flyweights 17, 18 are rigidly connected to one another and are arranged in a sliding and / or floating manner on the rotating body 9. Spring elements 30, 31 are arranged on both sides of the rotary shafts 7 in the longitudinal extension of the rotary body 9. When a first swing weight 17 reaches its maximum deflection, i.e. the maximum distance from the rotating shaft 7, the spring element 31, which is arranged between the rotating shaft 7 and the second swing weight 18, is compressed so that the spring force of the spring element 31 acts on the first swing weight 17 acting centrifugal force counteracts. Thus, the movement of the flyweight 17 is dampened before reaching the maximum deflection. Accordingly, when the second flywheel 18 reaches its maximum deflection, the spring element 30 is compressed between the rotary shaft 7 and the first flywheel 17, so that the spring force of the spring element 30 counteracts the centrifugal force acting on the second flywheel 18.
