PURPOSE: To reduce weight of a driving system by driving four driving wheels by means of a single two-output shaft motor and an inverter operable in wide range.
CONSTITUTION: A two-output shaft motor A is arranged in the center of a body frame 17, and an output shafts are arranged in an axle direction, and driving force is inputted to differential mechanisms 14a and 14b for front and rear and left and right wheels 15L, 15R, 16L and 16R through swivel joints 12a and 12b and propeller shafts 13a and 13b, and four-wheel drive is carried out. At this time, the differential mechanism 14a or 14b in either the front or the rear is formed in such a structure that rotational direction of the front wheels and the rear wheels are adjusted to each other by reversing rotational direction of the two-output shaft motor A. Thereby, a residential characteristic can be improved without increasing vehicle body weight.
