Abstract
The torque converter includes a torque input member and an impeller assembly operatively coupled with the torque input member. A turbine assembly is connected with the impeller and a lock-up clutch is interposed between the turbine assembly and the torque input member. The lock-up clutch provides torque translation between the torque input member and the turbine assembly and includes an annular piston mounted to the turbine assembly and a friction plate movably supported relative to the annular piston and operatively disposed between the annular piston and torque input member. A first friction member is operatively disposed between the friction plate and the torque input member, and a second friction member is operatively disposed between the friction plate and the annular piston. Torque is translated from the torque input member through the first friction member, the friction plate, the second friction member, and the annular piston to the turbine assembly.
