| 摘要 |
<p>The invention concerns a hydrokinetic coupling apparatus (10) comprising a front crankcase (20) provided with a wall (24), designed to be linked in rotation with a driving shaft, a front turbine wheel (50), designed to be linked in rotation with a driven shaft, including a first part forming a torus (52), and a second part (54) linking the torus in rotation with the driven shaft, a hydraulic circuit formed by a rear impeller wheel (40) and the torus (52), a piston (31), mounted mobile and arranged axially between the crankshaft (20) wall (24) and the turbine wheel (50), and defining with said wall a control chamber (34), radially delimited externally by at least a friction element (33), an inner annular space (100), located radially beneath the hydrodynamic circuit, and at least a vibration damping device (60), interposed between the driven and driving shafts, and housed in the annular space (100) and comprising at least an elastic member (64) adapted to co-operate with input and output elements, and at least an element of the second linking part (92, 93) of the turbine wheel (50) co-operates with at least an elastic member (64) of the damping device (60).</p> |
