Abstract
A torque converter includes a subassembly that comprises a lock up clutch and a torsional damper. The torsional damper has an input plate that is part of the lock up clutch. Front and back sheet metal retainers are attached to the input plate to retain a plurality of torque transmitting springs. An outer castellated margin of an output plate is disposed between the front and back sheet metal retainers and engages the torque transmitting springs for being driven by the input plate via the sheet metal retainers. In one embodiment the plates are also connected by a lost motion drive connection that limits relative angular travel to protect the torque transmitting springs from being overloaded. In another embodiment two identical sheet metal retainers are flange driven to simplify construction further and conserve more space.
