Starter unit for manual and automatic transmissions, etc. has bridging coupling with two coupling discs in friction connection with each other, and connected to pump wheel shell and turbine wheel of hydrodynamic coupling

摘要

The device has a hydrodynamic coupling (3) as starter element, and a bridging coupling (7) with two coupling discs (8,9). The first disc is connected non-turnable to a pump wheel shell (10) and the second disc is similarly connected to a turbine wheel (5) of the hydrodynamic coupling. The device also has elements (11), e.g. a pressure medium-charged piston (12), to generate contact pressure force to realize a friction connection between first and second coupling discs.
