Hydrodynamic torque converter for a drive arrangement comprises a bridge coupling for friction coupling of converter pump blades with converter turbine blades

摘要

Hydrodynamic torque converter (1) comprises a bridge coupling (8) for friction coupling of converter pump blades (35) with converter turbine blades (37). The bridge coupling has inner and outer coupling lamellae formed as coupling lamellae with a friction coating or without a friction coating. Flow channels are provided in at least one coupling lamella and lead radially inward from a chamber (100) between the pump blades and the turbine blades so that the bridge coupling can be cooled. Preferred Features: At least a part of the operating fluid stream is fed into the region of a bearing inner ring (40) of a free-wheel (39).
