The invention discloses a suspension control valve group which comprises a valve block, a filter, a signal transmitter, an overflow valve, a stop valve and four groups of control units, the filter, the signal transmitter, the overflow valve, the stop valve and the four groups of control units are arranged on the valve block, the valve block is provided with an oil inlet, an oil return port, a pressure measuring connector and four working oil ports, and each group of control units comprises an electromagnetic directional valve, an ascending speed regulating valve and a descending speed regulating valve. Adjustment of the maximum pressure in the suspension system is controlled by adjusting the overflow valve, detection can be conducted through the pressure measuring connector, the oil inlet speed is controlled by controlling the opening degree of the ascending speed adjusting valve, the oil return speed is controlled by controlling the opening degree of the descending speed adjusting valve, and oil way locking of the working oil port and the oil return port can be achieved by closing the stop valve. The pressure protection function of the valve group can be kept stable, the valve group has the advantage of fast replacement of fault parts, the overall structure is simple, installation is easy, connecting pipelines are simplified, occupation of the valve group on the space of a vehicle body is reduced, applicability is high, and the integrated structure facilitates improvement of operation reliability among all control units.
本发明公开了一种悬架控制阀组,包括阀块以及设在阀块上的过滤器、发讯器、溢流阀、截止阀和四组控制单元,阀块上设有进油口、回油口、测压接头和四个工作油口,每组控制单元包括电磁换向阀、上升调速阀和下降调速阀,通过调节溢流阀控制悬架系统内最大压力的调节,并可以通过测压接头进行检测,通过上升调速阀的开度控制实现进油速度的控制,通过下降调速阀的开度控制实现回油速度的控制,可通过关闭截止阀实现工作油口与回油口的油路闭锁,阀组压力保护功能可保持稳定,具备快速对故障件更换的优势,整体结构简单,安装容易,简化连接管路,降低阀组对车身空间的侵占,适用性强,且一体集成的结构便于提高各控制单元之间的作业可靠性。
