The invention belongs to the technical field of vehicle full-automatic suspensions, and particularly relates to a rotary hydraulic pressure distribution valve which comprises a valve body, a valve sleeve and a valve element, and the valve body is provided with three pump body valve ports connected with a hydraulic oil pump and two shock absorber valve ports connected with an upper cavity and a lower cavity of a shock absorber; the valve sleeve is assembled in the valve body in a sealed mode, three oil inlet cavities and two oil outlet cavities are formed between the valve sleeve and the valve body, and a plurality of valve sleeve oil passing grooves are formed in the valve sleeve in the circumferential direction. The valve element is coaxially and rotationally assembled in the valve sleeve, and a plurality of valve element oil passing grooves used for being matched with the valve sleeve oil passing grooves are formed in the circumferential direction of the valve element, so that in the rotating process of the valve element, oil ways between the pump body valve port and the corresponding valve sleeve oil passing grooves, oil ways between the valve element oil passing grooves and oil ways between the corresponding shock absorber valve port are communicated or blocked. Switching of oil ways is achieved in a valve element rotating mode, then pressure distribution is achieved, the shock absorber is controlled to provide continuous and adjustable damping force for a vehicle body, the structure is simple, and the use and maintenance cost is low.
本发明属于车辆全自动悬架技术领域,具体涉及一种旋转式液压压力分配阀,其包括阀体、阀套和阀芯,阀体上设有三个连接液压油泵的泵体阀口和两个连接减振器上腔和下腔连接的减振器阀口;阀套密封装配在阀体内,阀套与阀体之间形成三个进油腔室和两个出油腔室,阀套的圆周方向上设有多个阀套通油槽;阀芯同轴并转动装配在阀套内,阀芯的周向上设有多个用于与阀套通油槽相配合的阀芯通油槽,以在阀芯转动过程中,使泵体阀口与对应的阀套通油槽、阀芯通油槽以及对应的减振器阀口之间的油路连通或阻断。本发明采用阀芯转动的形式实现油路的切换,进而实现压力的分配,以控制减振器为车身提供连续且可调节的阻尼力,结构简单,使用和维护成本低。
