摘要： 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.

摘要： A torque limiter for a drive train includes a rotational axis, a first cover disc and a second cover disc, a central disc arranged axially between the cover discs, a first friction lining and a second friction lining, a radially outer connector and a radially inner connector, and a spring element. The first friction lining is for frictionally locking torque transmission between the first cover disc and the central disc, and the second friction lining is for frictionally locking torque transmission between the second cover disc and the central disc. The radially outer connector is permanently connected to the cover discs in a torque-transmitting manner, and the radially inner connector is permanently connected to the central disc in a torque-transmitting manner. The spring element is arranged between the central disc and the first friction lining or the second friction lining.

摘要： A centrifugal pendulum for a motor vehicle drivetrain includes a carrier, a pendulum mass, mounting for pivoting relative to the carrier, and a roller body. The carrier has a carrier roller track and the pendulum mass has a pendulum mass roller track. The roller body has a first rolling region arranged in the carrier roller track and a second rolling region arranged in the pendulum mass roller track. The carrier roller track is formed at least partially by an axially formed sheet-metal portion having a free edge, and the free edge faces away from the pendulum mass.

摘要： A friction device for a torsional vibration damper includes an axis of rotation, an input side with a first disc and a second disc, and an output side between the first disc and the second disc and rotatable relative to the input side. The output side has a first friction disc, a second friction disc, and a spring element between the first friction disc and the second friction disc. The spring element has first, second and third contact regions. At a first angle of rotation between the input side and the output side, an axial contact force between the first friction disc and the second friction disc is transmittable via the first contact region and the third contact region. At a second angle of rotation, different than the first angle of rotation, the axial contact force is transmittable via the second contact region and the third contact region.

摘要： The invention relates to clutch disc comprising a torsional vibration damper which has an inlet part and an outlet part and a spring device operatively arranged in the peripheral direction between the input part and the output part, wherein the spring device is formed from the first and second spring elements connected behind one another and separated by an intermediate flange, and a centrifugal pendulum which has a pendulum mass carrier arranged about an axis of rotation of the clutch disc and pendulum masses accommodated on same on pendulum paths for oscillation and arranged in a distributed manner over the periphery. In order to improve the insulation effect of the torsional vibration damper and the centrifugal pendulum and/or better adjust same to the required application, the pendulum mass carrier is coupled for conjoint rotation with the intermediate flange and centrally accommodated on the output part.

摘要： A torsional vibration damper includes an input side and an output side, first and second rolling bodies, an intermediate element for torque transmission between the input and output sides, and an energy storage element for supporting the intermediate element in an oscillating manner. The intermediate element has a first transmission path for rolling the first rolling body, and a second transmission path for rolling the second rolling body. The input side has a first counter path complementary to the first transmission path. The output side has a second counter path complementary to the second transmission path. The first rolling body is guided between the first transmission path and the first counter path, and the second rolling body is guided between the second transmission path and the second counter path. The energy storage element is arranged with a vector component that acts circumferentially on the intermediate element in a circumferential direction.

摘要： A pendulum rocker damper with a rotation axis includes an input side with first and second input-side counter tracks, an output side with first and second output-side counter tracks, a stored energy source, and rocker elements disposed at opposite axial ends of the stored energy source. Each of the rocker elements has three axially offset partial tracks forming an input-side roller track and an output-side roller track. A first input-side rolling element is clamped between the first input-side counter track and a first input-side roller track and a second input-side rolling element is clamped between the second input-side counter track and a second input-side roller track. A first output-side rolling element is clamped between the first output-side counter track and a second output-side roller track and a second output-side rolling element is clamped between the second output-side counter track and a second output-side roller track.

摘要： 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.
