The invention provides a semi-active control type shock absorber for a railway vehicle, and relates to the technical field of shock absorbers, an oil storage cylinder is sleeved outside a working cylinder, and an oil storage cavity is arranged between the oil storage cylinder and the working cylinder; the piston valve assembly is fixedly arranged at one end of the piston rod, the piston rod and the piston valve assembly are both arranged in the working cylinder, and the piston valve assembly moves in the working cylinder through the piston rod and divides the internal space of the working cylinder into a compression cavity and a stretching cavity; a guide assembly is arranged on one side of the working cylinder, an oil storage cylinder base is arranged on the other side of the oil storage cylinder and the other side of the working cylinder, and the oil guide pipe is arranged in the oil storage cavity. The electromagnetic regulating valve assembly, the electromagnetic switch valve assembly and the damping valve assembly are all fixedly arranged on the side face of the oil storage cylinder base. According to the semi-active control type shock absorber, the requirements of different dampers at the same speed of a vehicle can be met, the semi-active control type shock absorber gradually replaces an original passive shock absorber so as to meet various types of damping requirements, and more comfortable and excellent riding experience is brought to passengers.

    本发明提供一种轨道车辆半主动控制型减振器,涉及减振器技术领域,贮油缸套接在工作缸外部,贮油缸与工作缸之间设有贮油腔;活塞阀总成固定设置于活塞杆的一端,活塞杆和活塞阀总成均设置于工作缸内,活塞阀总成通过活塞杆在工作缸内进行移动,并将工作缸内部空间分为压缩腔和拉伸腔;工作缸的一侧设置有导向总成,贮油缸和工作缸的另一侧设置有贮油缸底座,导油管设置于贮油腔内;电磁调节阀总成、电磁开关阀总成和阻尼阀总成均固定设置于贮油缸底座的侧面。本发明可以满足车辆同一速度下不同阻尼的需求,半主动控制型减振器也将逐渐替代原有被动式减振器,以匹配各种类型的阻尼需求,给乘客带来更加舒适优异的乘坐体验。
