Torque transmission arrangement e.g. hydrodynamic torque converter for drive train of vehicle, has clutch piston that is mounted in radial inner portion of driven assembly and whose friction surfaces are frictionally engaged

摘要

The transmission arrangement has clutch assembly (30) that is arranged between housing assembly and driven assembly (50) for selectively producing and interrupting torque transmission between housing assembly and driven assembly. The clutch assembly includes clutch piston having rotatable friction surfaces (128,130) which are rotated around the rotation axis (A), by driven assembly. The friction surfaces of clutch piston are frictionally engaged and the clutch piston is mounted in radial inner portion of driven assembly.
