Abstract:
A torque converter assembly for receiving torque from an engine crankshaft assembly and transmitting torque to a transmission input shaft, the torque converter assembly comprising:a first torque converter sub-assembly having a first impeller adapted to be rotationally driven by the crankshaft assembly, a first turbine mounted adjacent the first impeller and drivable thereby, the first turbine adapted to be rotationally coupled to the transmission input shaft, and a first stator mounted between the first turbine and the first impeller; a second torque converter sub-assembly having a second impeller rotationally coupled to the first impeller, a second turbine mounted adjacent the second impeller and drivable thereby, the second turbine rotationally coupled to the first turbine, and a second stator mounted between the second turbine and the second impeller; a first one-way clutch rotationally coupled to at least one of the first stator and the second stator; and a stator shaft that is rotationally fixed and is coupled to the first one-way clutch.
