Assembly for transmitting rotational torque, and system including the same

A system comprising:

• a transmission comprising a transmission input extending along a transmission axis and configured to receive rotational torque from an output of a drive engine of a vehicle, and a transmission output configured to deliver rotational torque;
• and
• an assembly configured to transmit rotational torque between the output of the drive engine and said transmission input, said assembly comprising:
• a torque converter comprising,
• a torque converter input member disposed about a torque converter axis, and
• a torque converter output member disposed about said torque converter axis and rotatably coupled to said torque converter input member to receive rotational torque from said torque converter input member, wherein said torque converter output member is configured to deliver rotational torque to said transmission input, and
• a clutch assembly comprising,
• a disconnect clutch comprising a clutch input member that is configured to be rotatably coupled to the output of the drive engine, wherein said disconnect clutch has an engaged position where said clutch input member is rotatably coupled to said torque converter input member, and a disengaged position where said clutch input member is rotatably uncoupled to said torque converter input member, and
• a clutch housing disposed about said axis, wherein said clutch housing rotatably couples said clutch input member to said torque converter input member when said disconnect clutch is in said engaged position;
• wherein one of said clutch housing and said torque converter input member comprises a retention groove and the other of said clutch housing and said torque converter input member comprises a retention lever disposable in said retention groove to axially retain said clutch assembly to said torque converter with respect to said axis;
• wherein the other of said clutch housing and said torque converter input member comprises a chamfered surface configured to be engaged by said retention lever as said clutch housing moves along said axis toward said torque converter;
• and
• wherein said retention lever comprises a retention protrusion extending toward said retention groove, and wherein said retention lever is movable between a first retention position where said retention lever is engaged with said chamfered surface, and a second retention position where said retention protrusion is disposed in said retention groove to axially retain said clutch assembly to said torque converter with respect to said axis.
