The invention discloses a railway vehicle steering damper which comprises four sets of damping oil cylinders, the four sets of damping oil cylinders are installed between a vehicle body and a bogie, the damping oil cylinders are connected with an oil tank through a valve set, the valve set comprises a valve set support, the damping oil cylinders are fixedly installed on the valve set support, and the damping oil cylinders are connected with the oil tank through the valve set support. An electric pump used for pumping hydraulic oil is arranged in the valve set support, an outlet of the electric pump is connected with an electromagnetic valve through a hydraulic oil pipe, and a hydraulic lock is arranged between the electromagnetic valve and the damping oil cylinder. A thrust pressure-limiting valve and a tension pressure-limiting valve are mounted on the valve group bracket, and are both used for connecting an oil tank and a damping oil cylinder; the working state of the steering shock absorber is controlled through the hydraulic system, and the hydraulic system is used for reducing the lateral acting force between wheels and rails when an automatic auxiliary locomotive passes through a curve, so that the lateral acting force between a rim and the rails is reduced, rim abrasion is reduced, and the traction performance of the locomotive is improved.
