ABSTRACT:
A power transmission is provided including a pair of input shafts with a first gear train drivingly connecting the input shafts for equal inverse rotation. An output shaft is also provided and second gear train structure drivingly connects each of the input shafts to the output shaft for rotation of the latter in response to inverse rotation in the input shafts. Also, a powered shaft is provided and torque transmitting structure drivingly connects the powered shaft to a selected input shaft for rotation of either input shaft in the same direction in response to a given directional rotation of the powered shaft. The power transmission is duplicated in a second transmission with the output shafts of the power transmissions drivingly connected to opposite side drive wheels of a vehicle, whereby the power transmissions may be equally actuated for forward and reverse movement of the associated vehicle as well as inversely operated for steering the associated vehicle.
