Coupler buffer of railway truck

Abstract

The invention discloses a coupler buffer of a railway truck. The coupler buffer comprises a coupler, a coupler tail frame, a traction buffer unit and a compression buffer unit. The coupler tail frame is fixedly connected with the coupler, the traction buffer unit is arranged inside the coupler tail frame, the compression buffer unit is connected with the bottom of the coupler tail frame, the traction buffer unit comprises a plurality of pairs of overlapped traction buffer single units, first positioning grooves are formed in contact surfaces of each pair of traction buffer single units, and first positioning protrusions which are matched with the corresponding first positioning grooves are arranged on the contact surfaces of each pair of traction buffer single units. The traction buffer unit is compressed when realizing a buffer effect, and the first positioning protrusions on the traction buffer single units are inlaid in the first positioning grooves in a compression procedure, so that the traction buffer single units cannot transversely move relatively, and the integral traction buffer unit only can longitudinally move. The coupler buffer has the advantage that transverse movement of the traction buffer unit of the coupler buffer can be effectively prevented when the traction buffer unit moves longitudinally, so that the coupler buffer can be effectively protected against damage.

Description

technical field [0001] The invention relates to the technical field of railway freight car manufacturing, in particular to a coupler buffer of a railway freight car. Background technique [0002] The coupler buffer is an important part of the railway rolling stock. Through it, the railway freight car is connected with the locomotive, formed into a train, and transmits and buffers the traction force generated by the train when it is running or shunting and forming operations. and impact. [0003] Due to the need to buffer the traction force and impact force generated during train operation or shunting and marshalling operations, this requires the coupler buffer to have a two-way buffer function. At present, the structure of the coupler buffer with two-way buffer function is as follows: figure 1 As shown in , the coupler 01 is connected with the coupler frame 07, and the coupler frame 07 is provided with a slave plate 03 and a traction buffer unit 04 that is against the slav...

AI Technical Summary

Problems solved by technology

[0006] The current traction buffer unit is generally composed of round steel springs, rubber sheets, elastic damping elements, etc., but the traction buffer unit is prone to lateral movement while being compressed and moving in the longitudinal direction (that is, the moving direction of the vehicle), which may easily cause the coupler buffer. Instability, which may cause damage to the coupler buffer in severe cases
