Abstract
A hydrokinetic coupling apparatus (10), in particular for a motor vehicle, comprising a housing (12) provided with a wall (24), with globally transverse orientation, a turbine wheel (30), and a locking engagement (16), including a piston (50) linked in rotation with the housing (12) and a set (56) of parallel friction discs (120, 124, 122), which comprises two front (120) and rear (122) discs linked in rotation with the turbine wheel (30) and an intermediate disc (124) which is linked in rotation with the two elements constituted by the piston (50) and the transverse wall (24) of the housing (12). The piston (50) and the transverse wall (24) of the housing (12) are linked in rotation by straps (104) substantially elongated tangential to a circumference of the assembly and whereof the opposite ends are attached to these two elements, and the intermediate friction disc (124) is driven in rotation by means (114, 138) attaching the ends of the straps (104).
