摘要： A centrifugal pendulum includes a first support plate, being able to rotate around a rotation axis; a second support plate, facing the first support plate in the axial direction and fixed to the first support plate. A mass is disposed between the first support plate and the second support plate in the axial direction. The first support plate has a first protrusion extending axially, and the first protrusion is integrally formed with the first support plate and defines a first track. The mass has a through hole extending axially, and the through hole defines a second track. The first protrusion extends into said through hole such that the first track faces the second track in the radial direction. A roller is disposed between the first track and the second track in the radial direction, and is capable of rolling against the first track and the second track, such that the mass is able to move relative to the first and second support plates and apply a torque onto the first and second support plates. The present invention also discloses a torque transmitting device comprising the centrifugal pendulum and a vehicle.

摘要： The present disclosure relates to a damping system for a hydraulic coupling device, comprising: an output hub having a central axis and a torus which surrounds the central axis, a first track being arranged in the torus; a plurality of turbine mass assemblies uniformly distributed around the central axis, each turbine mass assembly comprising a turbine section, each turbine section carrying a plurality of blades and being provided with a second track corresponding to the first track; a roller that can roll along a roller track defined by the first track and a corresponding second track, so that the turbine mass assembly can move relative to the output hub and exert torque on the output hub; wherein each turbine mass assembly further comprises a mass plate fixedly connected to the turbine section, the output hub being arranged between the mass plate and the turbine section. The invention relates to a hydraulic coupling device comprising the damping system and a motor vehicle comprising the hydraulic coupling device.
