Abstract
The invention proposes an apparatus (10) comprising a casing (12, 20, 22) which has a wall (24) arranged to be coupled in rotation to a driving shaft, a turbine wheel (30) rotatable with a hub (34) which is arranged to be coupled in rotation to a driven shaft, a generally radially oriented piston (58) which is movable axially and coupled in rotation to the casing, and an annular friction disc (74), oriented generally radially and carrying two annular friction liners (76) which are adapted to be gripped axially by the piston (58) between, respectively, itself and the inner face (73), in facing relationship with it, of the radial wall (24) of the casing; the friction disc (74) is coupled at its radially inner periphery (94) to the hub (34) of the turbine (30); the piston (58) has means (100) at its radially outer periphery for meshing with a radially outer peripheral portion (26, 102) of the casing (22).
