Example Embodiment

[0037] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] figure 1 In the shown axle box rubber pad, the rubber layer 3' acts as a spring, and the elastic potential energy of the rubber layer 3' is converted into the upper liner 1' and the lower liner during the process of its resilience buffering the above-mentioned lateral force and longitudinal force. The vibration kinetic energy of the plate 2', and when there is no damping device in the axle box rubber pad, the elastic potential energy of the rubber layer 3' attenuates very slowly, resulting in the vibration kinetic energy of the upper liner 1' and the lower liner 2' attenuation is also very slow Slow, and then the vibration between the wheel set and the side frame cannot be eliminated, resulting in the serpentine mo...

Abstract

The invention discloses an axle box rubber cushion of a railway vehicle bogie. The axle box rubber cushion comprises an upper lining plate and a lower lining plate which are vertically distributed, wherein a damping device is arranged between the upper lining plate and the lower lining plate, and the damping device, the upper lining plate and the lower lining plate are arranged in a split manner, or the damping device is formed by the upper lining plate and the lower lining plate. The damping device is used for converting kinetic energy of transverse and/or longitudinal vibration of the upper lining plate and the lower lining plate into internal energy, thereby reducing the kinetic energy of vibration, avoiding snaking motion, caused by vibration, of wheel pairs, and further improving running stability and safety of a railway vehicle. The invention also discloses the railway vehicle bogie and the railway vehicle.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to an axle box rubber pad, a bogie and a railway vehicle. Background technique [0002] Railway vehicles generally include car body, bogie, brake device, coupler buffer device and other components. Among them, the function of bogie is to support the car body, guide the railway vehicle to run along the track, and bear various loads from the car body and track. [0003] The most common bogie for railway vehicles is the two-axle cast steel three-piece bogie, which includes components such as bolsters, wheelsets, spring damping devices, and braking devices. Usually, in order to improve the dynamic performance of railway vehicles and reduce the impact load between the tracks, axle box rubber pads are usually installed between the side frame of the bogie and the bearing saddle of the wheel set, so that the wheel set and the side frame pass through The axle box rubber pad is elas...
