Abstract
The hydrokinetic coupling apparatus includes a housing (12) capable of being rotatably locked on a driving shaft, a turbine wheel (14) capable of being rotatably locked on a driven shaft and a locking clutch (10) acting between the housing (12) and the turbine wheel (14), the said clutch including a piston (2) mounted so as to be axially mobile with respect to the turbine wheel (14), whilst being rotatably locked to the latter, and a counter-piston (3) associated with the housing (12). The piston (12) is interposed axially between the turbine wheel (14) and a mass (3), forming a counter-piston, pivotally mounted on the housing (12). The said mass (3) is coupled elastically to the said housing (12) by means of springs (7) mounted at the outer periphery of the mass (3) between a transverse wall of the housing (12) and a radial projection (31) on the mass (3).
