ABSTRACT:
In a lock-up torque converter, first and second input shells are rotatable and axially movable relative to each other. The second input shell is integrally provided with a pump impeller. A turbine runner is rotatable but axially fixed relative to an output shaft. A first clutch engages the turbine runner with a lock-up clutch plate during disengagement of the lock-up clutch plate from the first input shell and disengages the turbine runner from the lock-up clutch plate during engagement of the lock-up clutch plate with the first input shell. A second clutch engages the first and second input shells while allowing them to be axially movable relative to each other during disengagement of the lock-up clutch plate from the first input shell and disengages the first and second input shells during engagement of the lock-up clutch plate with the first input shell.
