Torque converter for use in road vehicle has first damping zone located radially outside second damping zone making better use of available space

摘要

A hydrodynamic torque converter (10) has a bridging clutch with a frictional surface (42,46) which may be engaged or disengaged with a turbine (24) on the housing wall (12). The converter further has a torsion oscillation damper (60) with first (62) and second (64) damping zones. The first damping zone is located radially outside the second.
