The present disclosure sets forth a one-way clutch. The one-way clutch can function with one or no races as opposed to conventional prior art one-way clutches. In so doing, the overall size and weight requirements of the one-way clutch are drastically reduced, which in turn drastically reduces the overall size and weight requirements of the transmission and vehicle employing the transmission as well. The present disclosure also provides a one-way clutch having an outer race provided by axially spaced plates. An inner race is rotatably mounted with respect to one of the plates and the inner race has a ratchet surface. Ratchet pawls are pivotably mounted with respect to the plates and have unidirectional engagement with the ratchet surface of the inner race. In addition to reducing material and labor production costs, such lessened size and weight penalties translate into higher transmission efficiency and better vehicle fuel economy.

One-way clutch operable with one or no races and without race pockets for locking elements

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.
