The invention discloses a transverse oil pressure shock absorber and a high-speed motor train unit applying the same, relates to the technical field of rail transit shock absorbers, and aims to solve the technical problems that damping force of an existing transverse oil pressure shock absorber is prone to attenuation, and the damping force is prone to instability or failure. In the transverse oil damper, a corrugated sealing ring is adopted as a guide sealing structure, and the corrugated sealing ring is used for reducing the sliding friction coefficient between a sealing piece and a piston rod; a piston valve system structure adopts a double-circulation core valve spring structure, so that two sets of valve systems are used for respectively controlling during stretching and compression; the bottom valve structure is provided with a first O-shaped sealing ring and a second O-shaped sealing ring, the first O-shaped sealing ring is located at the matched position of the shock absorber working cylinder and the bottom valve, a C-shaped opening is formed in the contact position of the shock absorber oil storage cylinder and the bottom valve, and the second O-shaped sealing ring is arranged on the periphery of the C-shaped opening.

    一种横向油压减振器及应用其的高速动车组,涉及轨道交通减振器技术领域,用于解决现有的横向油压减振器阻尼力容易造成衰减,以及阻尼力易出现不稳定或失效现象的技术问题。所述横向油压减振器中,导向密封结构采用波纹密封圈,且波纹密封圈用于减少密封件与活塞杆之间的滑动摩擦系数;活塞阀系结构采用双循环芯阀弹簧结构,以使拉伸和压缩时具有两套阀系分别进行控制;底阀结构具有第一O型密封圈和第二O型密封圈,第一O型密封圈位于减振器工作缸与底阀配合位置,减振器储油缸与底阀接触位置采用C型口,且位于C型口周边设置第二O型密封圈。
