The invention belongs to the technical field of vehicle engineering, and provides a vehicle multi-axle steering synchronizer which comprises steering axles, a steering gear box and an oil pump, the steering axles are installed at the front end and the rear end of a vehicle chassis, and each steering axle comprises a steering shaft, a steering oil cylinder installed on the side face of the steering shaft and a synchronous oil cylinder; the steering gear box is communicated with an oil inlet and an oil outlet of a steering oil cylinder of the steering axle and used for adjusting oil inlet and oil outlet of the steering oil cylinder of the steering axle to control stretching and retracting of the steering oil cylinder. The oil pump is communicated with the steering gear boxes through the three-way valve which is used for switching the oil pump to different steering gear boxes; the synchronous oil cylinders of different steering axles are communicated in a staggered mode, and the steering axles at the front end and the rear end of the chassis rotate synchronously. Steering synchronization of the steering wheels on the left side and the right side of the same steering axle and steering synchronization among a plurality of steering axles are achieved, and a steering gear box of one cab at the front end and the rear end of a vehicle is selected for driving operation. Only one person is needed for driving, turning around is not needed during two-way driving, and the vehicle is suitable for the environment with the small working face.
本发明属于车辆工程技术领域,提供了一种车辆多桥转向同步装置,包括转向桥、方向机以及油泵,转向桥安装于车辆底盘前后端,转向桥包括转向轴、安装在转向轴侧面的转向油缸和同步油缸;方向机与转向桥的转向油缸的进出油口连通,方向机用于调节转向桥的转向油缸的进油和出油控制转向油缸的伸缩;油泵通过三通阀与方向机接通,三通阀用于将油泵转接通不同的方向机;不同转向桥的同步油缸之间相互交错连通,底盘前后端的多个转向桥同步转动。本发明实现了同一转向桥左右两侧的转向轮的转向同步,多个转向桥之间的转向同步以及选择车辆前后端的一个驾驶室的方向机进行驾驶操作。仅需1人驾驶即可,在双向驾驶时无需掉头,适用于作业面较小环境。
