Abstract:
A powertrain system includes a flex plate, a transmission input shaft, a torque coupling, a one-way clutch, and a damper assembly. The flex plate is configured to be connected to a crankshaft of an engine. The torque coupling connects the transmission input shaft to the flex plate while allowing slip between the transmission input shaft and the flex plate. The one-way clutch is configured to couple the flex plate to the torque coupling. The damper assembly couples the flex plate to the one-way clutch and is configured to inhibit vibration transmission from the flex plate to the one-way clutch.
