The invention discloses a switch type primary vertical shock absorber for a high-speed train. The switch type primary vertical shock absorber comprises a cylinder body, a guide cover, a valve base, a piston rod and a piston assembly; the guide cover and the valve base are arranged on the cylinder body; a hollow oil storage cavity is machined in the cylinder body; a bottom valve is installed at the bottom of the oil storage cavity; the piston rod is installed on the guide cover; a piston assembly is installed on the piston rod extending into the cylinder body; an oil guide pipe is arranged on the outer side of the guide cover; a flow guide pipe communicated with the oil guide pipe is installed on the valve base; an electromagnetic valve is arranged on the valve base; and a high-frequency damping valve and a low-frequency damping valve are arranged on the valve base at the end, away from the electromagnetic valve, of the flow guide pipe. According to the shock absorber, the valve base, the bottom valve and the guide cover are arranged on the cylinder body, and the oil guide pipe connected with the guide cover and the valve base is arranged, so that when the piston assembly moves, the electromagnetic valve is matched to enable oil to flow through the high-frequency damping valve and the low-frequency damping valve to absorb vibration, and the shock absorber can cope with high-frequency vibration and low-frequency vibration in the train running process.

    本发明公开了一种高速列车用开关型一系垂向减振器,包括缸体、导向盖、阀座、活塞杆和活塞组件,缸体上分别设有导向盖和阀座,缸体上加工有中空的储油腔,储油腔底部安装有底阀,导向盖上安装有活塞杆,伸入缸体内的活塞杆上安装有活塞组件,导向盖外侧设有导油管,阀座上安装有与导油管连通的导流管,阀座上设有电磁阀,导流管远离电磁阀的一端的阀座上设有高频阻尼阀和低频阻尼阀。本发明通过在缸体上设置阀座、底阀和导向盖,并设置连接导向盖和阀座的导油管,可在活塞组件移动时,配合电磁阀使油液流经高频阻尼阀和低频阻尼阀来吸收振动,使减振器可应对列车行驶过程中的高频振动和低频振动。
