PURPOSE: An electric vehicle four-wheel driven transfer apparatus is provided to protect a motor safely from an overload and a counter electromotive force caused by the increase of a motor rotation speed at the high speed of four-wheel drive as well as at low speed. CONSTITUTION: An electric vehicle four-wheel driven transfer apparatus comprises a motor(6), and a converter(10). The motor generates power. The converter comprises a planetary gear train and a clutch. The planetary gear train is combined with a motor drive shaft(6a) connected with a decelerator by the medium of a pair of bearings(30), and rotates. The clutch is connected with the motor drive shaft and the planetary gear train, and delivers power to a differential gearing device. [Reference numerals] (4) Differential gear; (6) Driving motor |
