    摘要： A torsional vibration damper of a hydrokinetic torque-coupling device. The torsional vibration damper comprises a torque input member including first and second side plates axially spaced from and non-rotatably attached to one another, and a supporting member mounted therebetween, a unitary elastic member disposed between the first and second side plates and pivotable relative to and elastically coupled to the torque input member, and a resilient member disposed between the elastic member and the first side plate. The elastic member includes a core member rotatable relative the torque input member, and an elastic leaf integral with the core member and configured to elastically engage the supporting member. The elastic leaf has a proximal end non-moveably connected to the core member, a free distal end and a curved raceway portion disposed between the proximal and free distal ends of the at least one elastic leaf for bearing the supporting member.

    摘要： A hydrokinetic torque coupling device for a motor vehicle comprises an impeller wheel intended to be coupled to a crankshaft and adapted to hydrokinetically rotate a turbine wheel. The impeller wheel rotationally coupled to a cover at least partially accommodating the impeller wheel, the turbine wheel and the reactor. The turbine wheel is axially moves between an engaged position in which the turbine wheel and the impeller wheel are axially moved closer to each other and rotationally coupled together, and a disengaged position in which the turbine wheel and the impeller wheel are axially moved away from each other and rotationally uncoupled. The device comprises a bracing member axially extending between the turbine wheel and a part of the cover, with the bracing member being adapted to limit the axial motion of the turbine wheel toward the above-mentioned part of the cover, opposite the turbine wheel.

    摘要： 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).

    摘要： A hydrokinetic torque coupling device features an impeller, a casing having a first engagement surface, a damper assembly, a turbine-piston including a drive component with a second engagement surface, and a clutch plate having clutch plate engagement surfaces interposed between and axially movable relative to at least one of the first and second clutch plate engagement surfaces. The turbine-piston is axially displaceable relative to the casing to move the second engagement surface axially towards and away from the first engagement surface for positioning the hydrokinetic torque coupling device into and out of a lockup mode in which the first and second engagement surfaces and the clutch plate engagement surfaces frictionally interlock with one another to non-rotatably lock the casing relative to the input part of the damper assembly.
