Title: TORQUE TRANSMISSION DEVICE
Abstract:
The invention relates to a torque transmission device (1) comprising a torque input element (5) for coupling to a crankshaft of an engine, a torque output element (8) for coupling to an input shaft of a gearbox, damping means (13, 17) and clutch means (20, 18) mounted between the torque input element (5) and the torque output element (8), the clutch means comprising a piston (20) that moves axially between an engaged position in which the torque input element (5) is rotatably coupled to the torque output element (8) by means of the damping means (13, 17), and a disengaged position, characterised in that it comprises assistance means (24) that can exert an axial effort tending to return the piston (20) towards the engaged position thereof.
