Torque transmission arrangement i.e. hydrodynamic torque converter, has supporting element with supporting region for supporting driven element at supporting element and another supporting region for supporting element at housing assembly

摘要

The arrangement has clutch pistons (48) movable with a friction surface formation (44) for creating and canceling a frictional engagement of another friction surface formation (40). A radial inner piston supporting element (54) comprises an axial supporting region (72) for axially supporting a driven element (49) at the supporting element in a radial inner end region (70), and another axial supporting region (76) for supporting the supporting element at a housing assembly (12). A cylindrical section (68) is made of a metal sheet component. The supporting element is made of plastic material. The piston supporting element is formed as a forging or casting part.
