Abstract
A four-wheeled-electromotive cart includes a single motor and a direct axle driving mechanism for driving the axle of left and right front wheels by means of the motor. The single electric motor would cause no rotation speed difference between the left and right front wheels and hence constantly permits a smooth linear movement of the electromotive cart. The direct axle driving mechanism includes a relay shaft connected to the output shaft of the electric motor, a small-diameter bevel gear mounted on a lower end of the relay shaft, and a large-diameter bevel gear engaging with the small-diameter bevel gear. The front-wheel axle is spline-connected to the large-diameter bevel gear so as to be driven by the motor via the direct axle driving mechanism. Thus, the electromotive cart is allowed to smoothly start moving without sudden jolts or shocks caused by start of the motor rotation.
