The invention discloses a multifunctional transverse damping device for a subway. The multifunctional transverse damping device comprises a first damper and a second damper which are obliquely and symmetrically arranged. Hydraulic oil ways of the first damper and the second damper are communicated through a pipeline, and a damping valve block is mounted on the communicated pipeline; the first damper and the second damper each internally comprise an oil storage cylinder, a compression cavity and a stretching cavity which are sequentially connected through an oil way. The multifunctional transverse damping device for the subway can play a role of a traditional transverse damper and an anti-snaking damper; when a vehicle vibrates transversely, small damping force is provided, and the transverse damping effect similar to that of a traditional transverse damper is achieved, so the comfort is improved; when the vehicle moves in a snake shape, large damping force is provided, and the anti-snaking effect similar to that of a traditional anti-snaking damper is achieved, so the operation stability is improved; and the problem that at present, an anti-snaking damper cannot be installed due tolimitation of the installation space and cost of an urban rail transit vehicle bogie, and consequently the stability of a subway vehicle is insufficient is solved.

    本发明公开了一种地铁多功能横向减振装置,包括斜对称布置的第一减振器和第二减振器;第一减振器和第二减振器的液压油路通过管路连通,且在连通的管路上安装有阻尼阀块;第一减振器和第二减振器内均包括通过油路依次连接的储油缸、压缩腔和拉伸腔。该地铁多功能横向减振装置,可以起到和传统的横向减振器加上抗蛇行减振器的作用;在车辆横向振动时,提供较小的阻尼力,起到和传统横向减振器类似的横向减振作用,改善舒适性;在车辆蛇形运动时,提供较大的阻尼力,起到和传统抗蛇行减振器类似的抗蛇行作用,提高运行稳定性;解决目前受限于城市轨道交通车辆转向架的安装空间和成本无法安装抗蛇行减振器,导致地铁车辆稳定性不足的问题。
