Title:
HYDROKINETIC COUPLING APPARATUS, IN PARTICULAR FOR MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO2001036845
Kind Code:
A8
Abstract:
The invention concerns a hydrokinetic coupling apparatus, in particular for motor vehicle, comprising, axially arranged from the front rearwards, a housing transverse wall (58), with global radial orientation, adapted to be linked in rotation to a driving shaft, a turbine wheel (64) integral in rotation with a hub (68) designed to be linked in rotation with a driven shaft (72), an axially sliding piston (74), mounted sealed along a central ring (76) axially interposed between the housing transverse wall (58) and the turbine hub (68) and a rear stop (178) which limits the piston axial movements relative to the central ring in a direction corresponding to its movement away from the inner surface of the transverse wall and which prevents direct friction contact between the piston (74) and the hub (68) of the turbine wheel (64). The invention is characterised in that the stop (178) and the ring (76) are designed as a single piece.
