ABSTRACT:
A torque converter is provided with both a lock-up clutch and a disengaging clutch for use with a manual transmission. When the disengaging clutch is engaged, torque is transmittable through a torque converter impeller and turbine fluid coupling. When the lock-up clutch is engaged, torque is mechanically transmitted through the lock-up clutch to a manual transmission input shaft. A single control mechanism effects selective engagement and disengagement of both the lock-up clutch and the disengaging clutch. In an alternate embodiment of the present invention, a weight may be engaged and disengaged from various components within the torque converter to change the ratio of a moment of inertia of a power input mechanism and a power output mechanism defined by portions of the torque converter. A lock-up clutch in the alternate embodiment and the weight are also engaged and disengaged by a single control mechanism.
