1. A hydrokinetic torque coupling device for a motor vehicle, comprising a torque input element (11) intended to be coupled to a crankshaft (1),
a turbine wheel (4), an impeller wheel (3) rotationally coupled to the torque input element (11) and able to hydrokinetically drive a turbine wheel (4), damping means (18, 22), a torque output element (8) intended to be coupled to a transmission input shaft (2), clutch means (10) adapted to rotationally couple the torque input element (11) and the torque output element (8) in an engaged position, through damping means (18, 22), and able to rotationally uncouple the torque input element (11) and the torque output element (8) in a disengaged position, with the damping means (18, 22) being adapted to act against the rotation of the torque input element (11) relative to the torque output element (8), in the engaged position of the clutch means (10), with the clutch means (10) comprising a piston (25) which is movable between an engaged position wherein it is rotationally coupled to the torque input element (11) and a disengaged position wherein it is rotationally uncoupled from the torque input element (11) , with the damping means (18, 22) comprising at least one elastic blade (22) and a supporting member (18), with the elastic blade (22) being rotationally linked with the piston (25) or with the torque output element (8) respectively and being elastically maintained supported by said supporting member (18), with the supporting member (18) being carried by the torque output element (8) or by the piston (25) respectively, with said elastic blade (22) being adapted to bend upon rotation of the piston (25) relative to the torque output element (8). |
