The invention discloses a bi-directional driving multi-mode steering hydraulic control system which comprises a steering oil way, a front/rear cab steering gear, a first hydraulic source and a front/rear axle steering oil cylinder, a first reversing valve and a second reversing valve are arranged on the steering oil way, and each of the first reversing valve and the second reversing valve is provided with two groups of working ports, two groups of cut-off stations and two groups of access stations. The working port is configured to be disconnected with the steering oil way at the cut-off station and communicated with the steering oil way at the access station; the front/rear cab steering gear is communicated with the steering oil way through two groups of oil ports of the steering gear to form a loop; the first hydraulic source is communicated with the front/rear cab steering gear; two groups of cavities on two sides of a piston of the front axle steering oil cylinder are respectively communicated with one group of working ports of the first reversing valve; two groups of cavities on two sides of a piston of the rear axle steering oil cylinder are respectively communicated with a group of working ports of the second reversing valve; the hydraulic control system oil way can achieve the functions of front and rear wheel steering and four-wheel steering of a vehicle, and is simple in structure, excellent in stability and convenient to maintain.
本发明公开了一种双向驾驶多模式转向液压控制系统,包括转向油路、前/后驾驶室转向器、第一液压源及前/后桥转向油缸,其中,转向油路上设有第一换向阀和第二换向阀,第一换向阀和第二换向阀均具两组工作口、截止工位及通路工位,工作口配置为在截止工位下与转向油路断开且在通路工位下与转向油路连通;前/后驾驶室转向器各通过自身的两组油口与转向油路连通为回路;第一液压源连通前/后驾驶室转向器;前桥转向油缸的活塞两侧的两组腔室各连通第一换向阀的一组工作口连通;后桥转向油缸的活塞两侧的两组腔室各连通第二换向阀的一组工作口;本发明的液压控制系统油路可实现车辆的前后轮转向和四轮转向功能,结构简单,稳定性优异且便于维护。
