The invention relates to a chassis vibration absorber for inhibiting transverse vibration of a railway vehicle body, which comprises a bearing structure and a vibration reduction structure, the bearing structure comprises a supporting plate body internally provided with a transverse groove, a bearing rod used for fixing the supporting plate body to a vehicle body chassis, a cover plate used for covering and sealing the groove of the supporting plate body, and top plates detachably installed on the left side and the right side of the transverse groove in the supporting plate body. The vibration reduction structure is located in the space of the transverse groove and comprises a vibration reduction mass plate and damping lubricating oil, wherein the vibration reduction mass plate achieves transverse vibration reduction and provides rigidity through metal springs on the left side and the right side in the transverse direction, and the space between the vibration reduction mass plate and the inner wall of the transverse groove is filled with the damping lubricating oil for providing damping. Compared with the prior art, the chassis vibration absorber is advantageous in that the assembly mode is simple, the safety performance is reliable, the transverse vibration of the vehicle body is effectively controlled, the vibration noise of the vehicle body is reduced, and the running stability and riding comfort of the vehicle are improved.

    本发明涉及一种抑制轨道车辆车体横向振动的底架减振器,包括承载结构和减振结构,所述的承载结构包括内部开设横向凹槽的托板主体、用以将托板主体固定在车体底架上的承重杆、用以对托板主体的凹槽进行掩盖密封的盖板以及可拆卸的安装在托板主体上横向凹槽左右两侧位置处的顶板,所述的减振结构位于横向凹槽的空间内,包括通过横向左右两侧的金属弹簧实现横向减振并提供刚度的减振质量板以及填充在减振质量板与横向凹槽内壁之间空间内用以提供阻尼的阻尼润滑油。与现有技术相比,本发明具有装配方式简单、安全性能可靠、有效控制车体横向振动、降低车体振动噪声并提高车辆运行平稳性及乘坐舒适度等优点。
