Abstract: 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.

Abstract: A vehicle includes a vehicle engine and a transmission. A first electric motor is driveably connected to the transmission. A second electric motor is driveably connected to the vehicle engine. At least one selectively engagable clutch is located between the engine and the transmission to provide slip. The at least one clutch is engaged after the engine reaches a predetermined speed differential with the transmission.

Abstract: A transmission having an electric motor/generator includes a transmission housing and a bearing support rigidly connected to the transmission housing and substantially enclosed by the transmission housing. A stator housing is substantially enclosed by the transmission housing, and is rigidly joined to the bearing support by a plurality of rivets, such that torque may be transferred between the stator housing and bearing support. The stator housing may be formed from a first material, and the bearing support may be formed from a second material, different from the first material. The stator housing and bearing support meet at an interface region, which may be characterized by an absence of a welded connection between the stator housing and the bearing support. The interface region may be characterized as a slip fit, such that the stator housing and bearing support are matable by hand.

Abstract: A powertrain for a vehicle includes an engine, a transmission and a coupling system interconnecting the engine and the transmission. The coupling system includes an electric motor/generator. The electric motor/generator is coupled to an input shaft. An engine disconnect clutch interconnects the engine with the input shaft. A fluid coupling interconnects the input shaft and the transmission. The engine disconnect shaft is moveable between an engaged position and a disengaged position for starting the engine and/or isolating the electric motor/generator from the engine. The engine disconnect clutch includes a default position disconnecting the electric motor/generator from the engine.
