Patent ID: 7036645

Claim:
A rotating torque-transmitting apparatus comprising: a first rotatable transmission housing; a second rotatable transmission housing; a third rotatable transmission housing; a stationary transmission housing; first and second apply pistons slidably disposed in said stationary transmission housing; first and second torque-transmitting plate members drivingly connected with said first and second rotatable transmission housings respectively; third and fourth torque-transmitting plate members drivingly connected with said first and third rotatable transmission housings respectively first and second apply members; rotatable bearing means disposed between each said apply members and said apply pistons; return spring means disposed between each of said rotatable transmission housings and said apply members for urging said apply members axially in one direction relative to said first rotatable transmission housing; means secured to at least one of said apply members for limiting movement of said apply member in said one direction; and means for urging axial movement of said apply pistons and said apply members in an opposite direction to enforce frictional engagement between said first and second torque-transmitting plate members and said third and fourth torque-transmitting plate members wherein said pistons remains non-rotatable within said stationary housing.
