The invention provides a driven rear axle control system, a driven rear axle and a driven rear axle control method, relates to the field of driven axles, and adopts the scheme that a driving oil cylinder comprises a main oil cavity I, a main oil cavity II, a main oil cavity III and a main oil cavity IV, and the main oil cavity I and the main oil cavity IV are communicated through a steering gear control valve; the steering gear control valve can switch oil inlet and oil return of the first main oil cavity and the fourth main oil cavity, and the steering gear control valve is communicated with an oil tank. A piston rod of the centering oil cylinder is used for being connected with a steering knuckle arm of a rear axle, the centering oil cylinder comprises a first auxiliary oil cavity, a second auxiliary oil cavity, a third auxiliary oil cavity and a fourth auxiliary oil cavity, the first auxiliary oil cavity is communicated with the second main oil cavity through the control valve set, the second auxiliary oil cavity is communicated with the third main oil cavity through the control valve set, and the fourth auxiliary oil cavity is communicated with the third main oil cavity through the control valve set. The third auxiliary oil cavity is communicated with the fourth auxiliary oil cavity. According to the method, the vehicle can actively steer along with the front axle, and the method is suitable for road and off-road working conditions and steering under the low-speed working condition of 60 km/h or below.

    本发明提供了一种从动后桥的控制系统、从动后桥及从动后桥控制方法,涉及从动桥领域,采用的方案是:所述主动油缸包括主油腔一、主油腔二、主油腔三和主油腔四,所述主油腔一和所述主油腔四均通过转向器控制阀连通,所述转向器控制阀能够切换所述主油腔一和所述主油腔四的进油和回油,所述转向器控制阀与油箱连通;所述对中油缸的活塞杆用于与后桥的转向节臂连接,所述对中油缸包括副油腔一、副油腔二、副油腔三和副油腔四,所述副油腔一和所述主油腔二通过所述控制阀组连通,所述副油腔二与所述主油腔三通过所述控制阀组连通,所述副油腔三和所述副油腔四连通。本发明能够使得车辆跟随前部车桥的进行主动转向,适合公路及非公路工况,以及如60km/h以下低速工况转向。
