ABSTRACT:
A hydrokinetic torque converter transaxle having a hydrokinetic torque converter, two simple planetary gear units and a clutch-and-brake system situated concentrically with respect to the axis of a vehicle engine wherein the torque output member of the planetary gear units is located in midposition between the planetary gear units and the hydrokinetic converter. A drive chain forms a torque transfer drive from the axis of the converter to a parallel axis coinciding with the axis of a geared differential, a pair of half shafts being connected to side gears of the differential for powering traction wheels wherein the clutch-and-brake system and the planetary gear units as well as the drive chain are integrated one with respect to the other to provide a minimum axial dimension with respect to the axis of the engine crankshaft thereby facilitating the packaging of the transaxle in a limited space within the vehicle. The torque flow path from the turbine of the converter through the gearing and from the gearing to the torque transfer drive chain is accomplished by strategically positioned torque transfer sleeve shafts surrounding the axis of the converter.
