Title: TORQUE TRANSMISSION DEVICE
Abstract:
The invention relates to a torque transmission device (1) comprising a torque input element (5) intended to be coupled to a crankshaft of an engine, a torque output element (8) intended to be coupled to an input shaft of a gearbox, and shock absorption means (13, 17) mounted between the torque input element (5) and the torque output element (8), the torque output element (8) being able to pivot in relation to the torque input element (5) around an axis (X), against a resisting torque exerted by the shock absorption means (13, 17), the shock absorption means comprising at least one elastic blade (17) that can be elastically and radially held on a supporting body (13), and the elastic blade (17) being able to bend during the rotation of the torque input element (5) in relation to the torque output element (8). The device further comprises clutch means (20, 18) mounted between the torque input element (5) and the torque output element (8) and is characterised in that the supporting body is carried by the torque input element.
