Abstract
The invention concerns a hydrokinetic coupling apparatus comprising a wall (36) with globally transverse orientation and a central ring (52) along which the piston (50) is mounted sealingly sliding to define a control chamber (38) with variable volume, and comprising an annular disc (92) linking in rotation the piston (50) with the ring (52), which is axially arranged between the transverse wall and the piston (50), which is linked to the piston by elastically deformable tabs (90) and which comprises a central part (96) extending radially inwards opposite an inner surface (98) of the transverse wall (36) against which it is axially pressed and whereto it is fixed. The invention is characterised in that the ring (52) is axially secured to the central part (96) of the linking annular disc (92) relative to which the ring (52) is radially centered.
