Abstract

Disclosed is an intermittent bi-directional driving mechanism, which transmits rotating power in forward and reverse directions through a bi-directional driving wheel (4); during the start process after the rotating direction is changed, there is an intermittent pause for a driven wheel (5), during which period the actions of other parts can be completed. By utilizing the function of the intermittent pause of the bi-directional driving mechanism, a device for preventing reverse motion during a start from an uphill slope is provided herein. When a vehicle is moving in one of the four slope-driving states of forward on an uphill slope, forward on a downhill slope, reverse on an uphill slope, and reverse on a downhill slope, the device for preventing reverse motion gives the vehicle a reverse braking function when moving forward on an uphill slope, so that an anti-reverse motion vehicle is provided. The device for preventing reverse motion can improve the operating conditions of the driver, and ensures the transmission system of the vehicle runs stably and safely so as to reduce traffic accidents.
