ABSTRACT:
A hydrokinetic coupling apparatus for a motor vehicle including a crankcase (12), designed to link in rotation, about an axis X, an input shaft to an impeller wheel; a turbine wheel (18) designed to be linked in rotation to an output shaft (16) via hub (14) and a flange (24) transversely oriented extending radially outwards relative to the hub; a lockup clutch (28) coupling the input and output (16) shafts comprising a piston (30) for releasably connecting the turbine wheel (18) to a substantially transverse wall (20) of the crankcase (12) against which the piston (30) is urged to lock the coupling; and at least a friction stop (68) interposed axially between the turbine wheel (18) and the piston (30). A friction stop (68) is arranged radially beyond the outer periphery (100) of the flange (24).
