Hydrokinetic coupling for automobile comprises hub connected to driven shaft and turbine wheel and locking clutch coupling driving and driven shafts

摘要

The coupling comprises a hub (16) connected to a driven shaft and a turbine wheel (18) and a locking clutch (34) coupling the driving and driven shafts. A locking piston (36) can move axially between a wall (38) integral with the turbine wheel and a locking wall (20) of a casing (14) rotating with the driving shaft and an impulse wheel. A female sealing part (42) connected to the piston slides axially around a male sealing part (44) connected to the hub. Damper means comprise an input part (60A,60B) connected to a disc (56) clamped between the piston and the wall and an output part (64) connected to the hub. An Independent claim is included for a method of installing the coupling
