ABSTRACT:
A first input shaft and an output shaft are supported in axial alignment by a housing which contains oil and also supports an annular second input shaft coaxial with the output shaft. The input shafts may be selectively coupled to the output shaft by compressing corresponding clutch sets of interfitting annular plates and discs, and the output shaft may be quickly stopped by compressing a brake set of interfitting annular plates and discs. The brake set is disposed between the two clutch sets, and a pair of non-rotating fluid actuated pistons are arranged between the corresponding clutch sets and the brake set. The output shaft has fluid impeller hub portions for recirculating oil outwardly between the sets of plates and discs and the input shafts are driven by corresponding electric motors or by a single double-ended electric motor.
