The invention relates to a novel railway vehicle height adjusting device which comprises an integrated laser displacement sensor, a processor and an electromagnetic valve, the electromagnetic valve comprises a shell, a valve head and a piston, an air storage cylinder pipeline connector, an air spring pipeline connector and an air outlet are formed in the shell, and the top of the valve head abuts against the air storage cylinder pipeline connector to form a check valve. The bottom of the valve head abuts against the air spring pipeline connector and the end of the piston, and an air spring air inlet valve and an air spring air outlet valve are formed respectively. A laser displacement sensor measures the vertical relative displacement between the vehicle body and the bogie and transmits the vertical relative displacement to the processor, and the processor conducts logical judgment according to the vertical relative displacement and outputs corresponding instructions to the electromagnetic valve to control opening or closing of the check valve, the air spring air inlet valve and the air spring exhaust valve. Therefore, the air spring is inflated and deflated. The dynamic occupied space is small, the number of parts is reduced, and the weight is reduced; the failure rate is reduced, and overhaul and maintenance are facilitated.
本发明涉及一种新型轨道车辆高度调整装置,包括一体化集成式的激光位移传感器、处理器以及电磁阀,电磁阀包括壳体、阀头和活塞,壳体上设有储风缸管路接口、空气弹簧管路接口以及排风口,阀头的顶部与储风缸管路接口相抵,形成止回阀,阀头的底部分别与空气弹簧管路接口、活塞的端部相抵,分别形成空气弹簧进气阀和空气弹簧排气阀;激光位移传感器测量车体与转向架之间的垂向相对位移并将其传给处理器,处理器根据垂向相对位移进行逻辑判断并输出相应的指令至电磁阀,控制止回阀、空气弹簧进气阀和空气弹簧排气阀的开启或者关闭,以实现对空气弹簧的充、放气。本发明动态占用空间小,简化了零部件数量,减轻重量;降低了故障率,便于检修维护。
