ABSTRACT:
A power transmitting apparatus for use in a transportation vehicle includes a motor shaft of a vehicle-driving motor, an input shaft operatively connecting with the motor shaft, output shafts provided in parallel with the input shaft to be connected with driven wheels of the vehicle, and a transmitting mechanism for transmitting driving power from the input shaft to the output shafts. The opposite end portions of the motor shaft are supported by a pair of motor shaft bearings, and one of the motor shaft end portions supports one of the opposite end portions of the input shaft in such a manner that the motor shaft can transmit driving power from the vehicle-driving motor to the input shaft. The other end portion of the input shaft is supported by another bearing, and the transmitting gearing is disposed adjacent to the other end portion of the input shaft remotely from the section where the one end portion of the input shaft is supported. This arrangement can make unnecessary one separate bearing to support the one end portion of the input shaft of the speed-reducing mechanism, and hence reduce the number of the necessary bearings. The arrangement can also substantially reduce the axial length of the housing necessary for receiving and retaining the bearings. Consequently, the size and weight of the power transmitting apparatus can be reduced.
