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