OUTPUT TRANSMISSION FOR VEHICLE, AND VEHICLE-DRIVING ELECTRIC MACHINERY SYSTEM USING IT

摘要

PROBLEM TO BE SOLVED: To provide a compact output transmission for a vehicle having high torque transmission efficiency of a reduction gear mechanism and high reduction gear ratio, and a vehicle-driving electric machinery system using it. SOLUTION: The output transmission comprises a motor 10, a reduction gear unit 12 for decelerating the rotation of the motor 10, and a differential gear unit 14 for distributing the output decelerated by the reduction gear unit 12 to left and right wheels. The reduction gear unit 12 is a reduction gear mechanism including a plurality of gears mounted on a shaft which is rotatably held by a housing in a fixed position. The reduction gear unit 12 and the differential gear unit 14 are arranged within an area facing an axial end face of the motor 10. COPYRIGHT: (C)2005,JPO&NCIPI
