Hydrokinetic torque coupling device for a motor vehicle
Abstract:
The disclosure describes a hydrokinetic torque coupling device for a motor vehicle. The coupling device includes a torque input element (11) intended to be coupled to a crankshaft (1), an impeller wheel (3) rotationally coupled to the torque input element (11) and able to hydrokinetically drive a turbine wheel (4). The turbine wheel, in turn, drives a torque output element (8) intended to be coupled to a transmission input shaft (2). The device further includes a clutch (10) able to rotationally couple and uncouple the torque input element (11) and the torque output element (8) between engaged and disengaged positions. When the clutch is in an engaged position, torque passes from the torque input element (11) to the torque output element (8) through an included damper system (18, 22).
