摘要

The gear box (2) has an axle (1) whose left and right wheels (8a,8b) are superimposed with traveling and steering drive units (3a,3b). The wheels are driven in same direction. The traveling drive unit and steering drive unit are assigned to wheels, so that rotational speed difference is exerted on wheels. The traveling drive unit and steering drive unit are arranged in the adjacent regions of wheels. The traveling drive unit is equipped with a central drive axle (4) for driving the wheels, and/or steering drive unit is cooperated with a central steering axle (6).
