Housing and friction surface unit for hydrodynamic coupling esp. torque converter has housing and friction surface element with friction surface areas and structured surfaces

摘要

A first side (14) of the housing (10) has a friction surface area (16) for a bridging coupling (100) for the coupling unit. In the area of the friction surface, the housing is made by forming a metal component, and a section of the opposite second side (20) of the housing is supplied with a surface structure (24) at the same time. A friction surface element (52) with friction surface area (64) is similarly formed and has a similar opposite side with structured surface (86).
