The invention provides a workshop anti-snaking shock absorber which comprises a working cylinder, a guide cover at the upper end of the working cylinder and a bottom valve seat at the lower end of the working cylinder, a discharge through hole consistent with a piston in motion direction is formed in a piston in the working cylinder of the anti-snaking shock absorber, a discharge rod is inserted into the through hole and is a long rod piece, the middle of the discharge rod is a thick rod section, and the bottom valve seat is connected with the guide cover. Two ends are thin rod sections; the thick rod section and the drainage through hole in the piston are matched, sealed and connected in a relatively sliding manner; when the shock absorber is in a compressed or stretched state, the piston is in a compressed position or a stretched position, an annular gap is formed between the piston and the slender rod section, and the upper cavity and the lower cavity of the working cylinder are communicated through the annular gap. According to the invention, high resistance can be established during linear high-speed driving of the vehicle, so that snakelike movement of the vehicle can be suppressed; during large-stroke work, stroke control of the shock absorber is achieved, the structure is simple, and the sealing effect is good.

    本发明提供一种车间抗蛇行减振器,车间抗蛇行减振器包括工作缸、其上端的导向盖和下端的底阀座,在抗蛇行减振器工作缸内的活塞上设置一个活塞运动方向一致的泄流通孔,通孔内插入一个泄流杆,所述泄流杆为长杆件,中间为粗杆段,两端为细杆段;粗杆段和活塞上的泄流通孔相配合,密封且可相对滑动连接;当减振器在压缩或拉伸状态时,活塞处于压缩位置或者拉伸位置,活塞和细杆段之间形成环形间隙,环形间隙导通工作缸的上下腔。本发明有利于车辆直线高速行驶时建立起高阻力,实现对车辆蛇行运动的阻遏;在大行程工作时,实现减振器的行程控制,结构简单,密封效果好。
