US Patent 7191879 Hydrokinetic coupling apparatus and method for mounting same

A coupling apparatus for a motor vehicle, including a hub designed to link in rotation an output shaft and a turbine wheel a clutch for locking the coupling between the input shaft and output shaft. A locking piston is axially mobile between a wall integral with the turbine wheel and a wall for locking a crankcase designed rotatable link the input shaft and an impeller wheel. A female member of sealing mechanism, linked to the piston axially about a male member of the sealing mechanism, linked to the hub. A damping mechanism is clamped between the piston and the wall and an output member linked to the hub. The male member and the damping output member are each mounted on the hub or born by a member mounted on the hub.
