Transmission with internal isolator and by-pass clutch

摘要

A transmission includes a housing defining a sealed interior and an input hub rotatably coupled to the housing. A gear set is disposed within the housing and configured for receiving a torque from an engine. The transmission further includes an isolator assembly and a bypass clutch, each disposed within the sealed interior of the housing. The isolator assembly is configured for selectively damping drivetrain inertia and/or vibration. The bypass clutch selectively engages and disengages the isolator assembly.

1. A transmission for a vehicle, the transmission comprising:
a housing defining an interior and configured for attachment to an engine, wherein said interior is substantially enclosed and bounded by the housing; an input hub rotatably supported by said housing for rotation about a longitudinal axis, wherein said input hub is partially disposed within said interior and extends through an opening in said housing for connection to a crankshaft of the engine outside of said interior of said housing for receiving a torque from the engine; and an isolator assembly mounted to said input hub and disposed within said interior of said housing and configured for damping drivetrain inertia or vibration; wherein said isolator assembly includes an isolator plate mounted to said input hub within said interior and extending radially outward from said input hub relative to said longitudinal axis, said isolator plate rotatable with said input hub about said longitudinal axis; and a gear set disposed within said interior, and wherein said isolator assembly includes an output cage disposed within said interior and coupled to said gear set and selectively connected in torque communication to said isolator plate.
