Document Type and Number:
WIPO Patent Application WO/2021/088916
Kind Code:
A1
Abstract:
Disclosed are a damping system for a hydrodynamic coupling device, a hydrodynamic coupling device including the damping system, and a motor vehicle comprising the hydrodynamic coupling device. The damping system for a hydrodynamic coupling device comprises: an output hub (101, 201), which is provided with a central axis (X) and a ring surface part (102, 202) around the central axis (X), wherein a first track is provided in the ring surface part (102, 202); a plurality of turbine mass assemblies (104, 204), which are evenly distributed around the central axis (X), wherein each of the turbine mass assemblies (104, 204) comprises a turbine section (105, 205), and each turbine section (105, 205) carries a plurality of blades and is provided with a second track corresponding to the first track; and a roller (107, 207), which can roll along a roller track defined by the first track and the corresponding second track such that the turbine mass assemblies (104, 204) can move relative to the output hub (101, 201) and exert torque on the output hub (101, 201), wherein each of the turbine mass assemblies (104, 204) further comprises a mass plate (108, 208) fixedly connected to the turbine section (105, 205), and the output hub (101, 201) is arranged between the mass plate (108, 208) and the turbine section (105, 205). According to the solution, the structure of the hydraulic coupling device is simplified, the number of components can be greatly reduced, manufacturing and mounting processes are simplified, and high cost benefits are achieved.
