Hydrokinetic coupling for automobile comprises casing transverse front wall with bearing surface for friction lining, rear turbine wheel and locking friction clutch with rear piston

摘要

The hydrokinetic coupling comprises a casing (12) transverse front wall (18) which comprises a bearing surface (52) on its internal face. There is a rear turbine wheel (24) and a locking friction clutch (14). The clutch comprises a rear piston (28), which can move axially relative to the casing front wall, and a friction lining (34,36) which is axially clamped between a piston bearing surface (54) and the casing bearing surface.
