The invention provides a vehicle steering centering hydraulic control system and a vehicle, and relates to the technical field of hydraulic control, the vehicle steering centering hydraulic control system comprises a steering gear, a left front wheel steering oil cylinder group, a left rear wheel steering oil cylinder group, a right front wheel steering oil cylinder group, a right rear wheel steering oil cylinder group, an electromagnetic proportional multi-way valve group and an oil tank, any steering oil cylinder set comprises a steering oil cylinder and a steering knuckle arm, the axis of the steering knuckle arm is used for being connected with the center of a wheel, the steering oil cylinder is used for driving the steering knuckle arm to rotate with the axis of the steering knuckle arm as the axis, an oil outlet of the steering gear is connected with a large cavity of the steering oil cylinder, and an oil outlet of the electromagnetic proportional multi-way valve set is connected with large cavities of all the steering oil cylinders. Hydraulic oil is controlled to enter or be discharged out of a large cavity of the steering oil cylinder by changing a current signal of the electromagnetic proportional multi-way valve, and then the piston rod of the steering oil cylinder is controlled to stretch out and draw back, so that the piston rod of the steering oil cylinder returns to the original position, wheels are straightened, and multiple sets of wheels are centered.

    本发明提供了一种车辆转向对中液压控制系统及车辆,涉及液压控制技术领域,本发明包括转向器、左前轮转向油缸组、左后轮转向油缸组、右前轮转向油缸组、右后轮转向油缸组、电磁比例多路阀组及油箱,任一转向油缸组包括转向油缸及转向节臂,转向节臂的轴心用于与车轮的中心连接,转向油缸用于驱动转向节臂以其轴心为轴转动,转向器的出油口分别与转向油缸的大腔连接,电磁比例多路阀组的出油口与全部转向油缸的大腔连接,本发明通过改变电磁比例多路阀的电流信号,控制液压油进入或排出转向油缸的大腔,进而控制转向油缸的活塞杆伸缩,使转向油缸的活塞杆回到原位,使车轮摆正,多组车轮完成对中。
