| 摘要 |
The invention concerns a hydrokinetic coupling apparatus, in particular for a motor vehicle, comprising: 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 a 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). The invention is characterised in that the friction stop (68) is arranged radially beyond the outer periphery (100) of the flange (24).
