- the first bearing element is operatively connected to a shaft drive and the second bearing element is connectable via means to a wheel carrier of the motor vehicle, so that during a rebound / rebound movement of the wheel carrier a rotational movement of the second bearing element relative to the motor vehicle body causes the second rotational angle ⁇ .
- the rotary damper comprises a control device which regulates the angular velocity ⁇ ⁇ and / or the torque Mo of the first bearing element about the first axis as a function of the rotational angle ⁇ and / or the torque ⁇ ⁇ of the second position element about the second axis via the shaft drive.
- the first bearing element is designed in the form of a hollow shaft, in the interior of which the flywheel is rotatably supported by the rotational angle ⁇ .
- the second bearing element is two orthogonally aligned to the second axis bearing legs and two aligned parallel to the second axis, the two bearing legs interconnecting bearing struts comprising formed, wherein the first bearing element between the two Lagerstre- ben around the first rotation angle ⁇ is rotatably mounted.
- the inventive design a rotary damper in which the damping effect is due to a gimbal-mounted on the vehicle body, gyroscopically acting flywheel, and due to the formation of the second bearing element has a particularly compact design as a hollow shaft.
- the flywheel in the form of a circumferential ring having a shaft - hereinafter also referred to as flywheel - is formed, wherein the flywheel is formed as a hollow part, in the interior of the drive of the flywheel is integrated.
- This embodiment has the advantage that a particularly space-saving construction is made possible due to the nested arrangement of flywheel and drive.
- the drive of the flywheel arranged or integrated into the flywheel is preferably designed as an electric motor whose stator is fixedly connected to the first bearing element and whose rotor is the flywheel designed as a hollow part.
- the flywheel formed as a hollow part is formed with a rib structure.
- the ribbed structure proves to be particularly advantageous, since on the one hand a weight-optimized construction is made possible on the other hand, and on the other hand cooling of the internal electric motor is ensured due to the ribs.
- the circumferential ring is formed of a different material from the remaining material of the flywheel, wherein the material of the circumferential ring has a higher density than the remaining material of the flywheel. This ensures that the inertia tensor of the flywheel necessary for the gyroscopic effect is provided in a compact manner.
- the first bearing element is arranged in a housing arranged on the second bearing element.
- the shaft drive of the first bearing element is flanged to a bearing strut of the second bearing element.
- the shaft motor is preferably designed in the form of an electric motor.
- a further advantageous embodiment of the invention provides that between the first and second bearing element a stop limiting the rotational movement of the first bearing element is arranged, wherein the stop is arranged such that the rotational angle of the first bearing element to an interval - ⁇ / 2 ⁇ ⁇ + ⁇ / 2 is limited.
- Fig. 1 is a schematic representation of the operation of a
- FIG. 2 is a view obliquely from above of a constructive design of the rotary damper of Fig. 1, and
- FIG. 3 is a sectional view of the rotary damper of FIG. 2
- the rotary damper 10 comprises a rotating about an axis of rotation 12 at the angular velocity ⁇ ⁇ rotating flywheel 14 which is gimbaled via a first bearing element 16 and a second bearing element 18.
- the flywheel 14 is rotatably supported by the rotational angle ⁇ on the first bearing element 16 and the first bearing element 16 is rotatably mounted on the second bearing element 18 about an orthogonal to the rotational axis 12 of the flywheel 14 aligned first axis 16a by a rotation angle ⁇ and the second bearing element 18 is around a orthogonal to the first axis 16a aligned second axis 18a by a second rotation angle ⁇ rotatably mounted on the motor vehicle body 100.
- the rotational damper 10 shown schematically uses the effect of rotational inertia to initiate forces in the chassis at a suitable location. These forces are intended to replace and extend the function of a conventional damper element.
- the flywheel 14 rotates at the angular velocity ⁇ ⁇ about the axis of rotation 12.
- a torque M ⁇ is effective on the first axis 16a of the first bearing element 16
- a torque ⁇ ⁇ arises around the axis second axis 18a.
- the moments lead to an angular velocity of the first or second bearing element 16, 18.
- a torque M ⁇ thus leads to an angular velocity ⁇ ⁇ of the first bearing element 16.
- This rotation alters the direction of the angular velocity vector ⁇ ⁇ of the flywheel 14 Disturbance, the rotating flywheel 14 reacts with the mentioned precession ⁇ .
- the angular velocity ⁇ ⁇ of the flywheel 14 will increase due to the feedback effect.
- the excess energy is stored in the rotary motion of the flywheel 14 in the form of kinetic energy.
- the transmission ratio of the individual moments is determined by the rotational inertia of the flywheel 14.

If a counter-moment M ⁇ is applied to the angular velocity ⁇ ⁇ of the first bearing element 16, then the relative movement of the bearing element 16 around the first axis 16 a is damped. This in turn leads to damping of the angular velocity ⁇ of the second bearing element 18 about the second axis 18a. Depending on the magnitude of the amount of the counter-torque M ⁇ attenuation is stronger or weaker.
- the rotary damper 10 can also be used as an actuator to actively provide vertical forces on the wheel and thus to take over functions of an active chassis.

- the first one is
- Bearing element 16 is formed in the form of a hollow shaft, inside which the flywheel 14 is rotatably mounted.
- the flywheel 14 in the form of a circumferential ring 14a having a shaft - hereinafter also referred to as flywheel 14 - formed, which in turn is formed as a hollow part, and in the interior of which is necessary to drive the flywheel drive 22 is mounted.
- the peripheral ring 14a of the flywheel 14 is formed from a material different from the rest of the material of the flywheel 14, wherein the material of the circumferential ring 14a has a higher density than the remaining material of the flywheel 14.
- the drive 22 of the flywheel 14 is presently designed as an electric motor whose stator is fixedly connected to the first bearing element 16 and whose rotor designed as a hollow part flywheel 14 is.
- the flywheel 14 is formed with a rib structure.
- the ribbed structure proves to be particularly advantageous, since on the one hand a weight-optimized construction is made possible on the other hand, and on the other hand cooling of the internal electric motor is ensured due to the ribs.
