Abstract
The invention concerns a hydrokinetic apparatus, in particular for motor vehicle, comprising a casing (10); a turbine wheel (16) secured in rotation to a hub (30); a lock-clutch comprising a piston (50) whereof the radially inner part (54) is mounted sliding along an outer cylindrical shaft (58) belonging to the central ring called piston (50, 54) whereof a rear end surface (64) extends opposite a transverse surface belonging to the turbine wheel (16)/hub (30, 86) assembly, and comprising stop means (84) axially interposed between the central ring and the turbine wheel/hub assembly. The invention is characterised in that are provided radial centering means for axial stop (84) relative to the hub (30, 5) or relative to the piston (50, 54) or relative to the web (104).
