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.
