A torsional vibration damper includes an input part for introducing a torque, two intermediate elements, an energy storage element designed as a compression spring that acts on the intermediate elements, an output part for discharging a vibration-damped torque, and an elastic or resilient compensation part provided between the output part and the intermediate elements. The intermediate elements are designed as pendulum rockers and are movement-coupled to the input part. Each of the intermediate elements can move towards and away from the other in a linear motion. The output part is movement-coupled to the intermediate elements and rotatable relative to the intermediate elements. The compensation part is for eliminating play of the intermediate elements relative to the output part in an axial direction.

There is provided a translational inerter assembly for damping movement of a flight control surface of an aircraft with a support structure. The translational inerter assembly includes a press fit element rotatably disposed within the flight control surface. The translational inerter assembly further includes an inertia element disposed in the press fit element. The translational inerter assembly further includes a torsion bar coupled to the inertia element and to the support structure of the aircraft, such that when the flight control surface rotates, the inertia element translates, and movement of the flight control surface is dampened.

A linear damper includes a rack, a carriage, a gear assembly, and a spring. The rack includes a connector. The carriage is slidably engaged with the rack. The gear assembly is between the carriage and the rack. The spring is secured to the rack to selectively urge the carriage away from the connector.

A torsional vibration damper (10) with a torque limiter, in particular for a clutch plate within a drive train of a motor vehicle, includes an input part (14) which is mounted such that it can be rotated about a rotational axis (12), an output part (18) which is arranged such that it can be rotated counter to the action of a spring device (16) to a limited extent about the rotational axis (12) with respect to the input part (14), and at least two torque-transmitting intermediate elements (20) arranged between the input part (14) and the output part (18) so as to move radially by cam mechanisms (22) in the case of a relative rotation of the input part (14) and the output part (18). In the case of a relative rotation between the input part and the output part, a torsional characteristic curve (32) of a drive torque over the rotary angle is configured by way of the configuration of the cam mechanisms (22) and/or a configuration of the spring device (16), so the torsional characteristic curve (32) has a damper stage (34) and an end stage (36) which adjoins the damper stage (34), he damper stage (34) specifies a damper capacity of the drive torque over the rotary angle, and the end stage (36) includes a torque limitation of the drive torque over the rotary angle.

A torque fluctuation inhibiting device includes a mass body. The mass body disposed to be rotatable with a rotor and be rotatable relatively to the rotor. Each of a plurality of centrifugal elements is radially movable by a centrifugal force that acts thereon in rotation of the rotor and the mass body. When a relative displacement is produced between the rotor and the mass body in a rotational direction while the centrifugal force is acting on the each of the plurality of centrifugal elements, each of a plurality of cam mechanisms converts the centrifugal force into a circumferential force directed to reduce the relative displacement. A plurality of restriction members allow the plurality of centrifugal elements to move in actuation of the plurality of cam mechanisms, and restrict the plurality of centrifugal elements from moving radially inward in non-actuation of the plurality of cam mechanisms.

A torsional vibration damper includes an input side for receiving a torque, an output side for dispensing the torque, an intermediate element arranged for torque transmission between the input side and the output side, an energy storage element supporting the intermediate element such that it can vibrate relative to the input side and the output side, and a roll body. The intermediate element has a transmission path for the roll body. The input side or the output side forms a path side with a counter path that is complementary to the transmission path, and the other of the input side or the output side forms a force side. The roll body is guided in a rotatable manner between the transmission path and the counter path, and the energy storage element connects the force side to the intermediate element for torque transmission.

A torsional vibration damper includes an input part for introducing a torque, a first cam mechanism, an intermediate element, a compression spring engaged with the intermediate element, a second cam mechanism for discharging a vibration-damped torque, and a frictional element for friction damping. The intermediate element is coupled to the input part via the first cam mechanism such that a relative rotation between the input part and the intermediate element is converted into a linear movement of the intermediate element radially inward or radially outward. The output part is coupled to the intermediate element via the second cam mechanism such that a linear movement of the intermediate element is converted into a relative rotation between the output part and the intermediate element. The frictional element is pressed against the intermediate element or the output part. The frictional element may be movement-coupled to the intermediate element or the output part.

A rotating inertia mass damper of a damper device comprises a planetary gear including a driven member that has external teeth and that serves as a sun gear; a plurality of pinion gears; first and second input plate members that are configured to support the plurality of pinion gears in a rotatable manner and that serve as a carrier; and a ring gear that is engaged with the plurality of pinion gears and that serves as a mass body. The ring gear has two gear main bodies that are arranged along an axial direction of the planetary gear and that are coupled with each other. Internal teeth of the two gear main bodies are shifted to each other in a circumferential direction of the gear main bodies.
