  • Patent number: 12241516
    Abstract: In a damping system for a hydraulic coupling device includes an output hub having a central axis and an annulus which surrounds the central axis, first tracks are arranged in the annulus, and a plurality of turbine mass assemblies are uniformly distributed around the central axis. Each turbine mass assembly comprises a turbine section carrying a plurality of blades and being provided with a second track corresponding to a respective first track. A roller can roll along a roller track defined by a 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. 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.

  • Patent number: 11913518
    Abstract: 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.

  • Patent number: 11773953
    Abstract: A torque converter includes a pump shell having pump blades; a turbine shell having a support portion supporting turbine blades, wherein the turbine blades are driven by the pump blades via a fluid to rotate about a rotational axis. The turbine shell further has a flange portion extending outward at the radially outside of the support portion and is integrally formed with the support portion. The torque converter further comprises a vibration damping device, the mass of which is mounted on the flange portion and configured to be movable relative to the flange portion and apply a torque to the turbine shell, thereby damping the torque vibration on the turbine shell. In addition, the invention also discloses a vehicle comprising the torque converter.
