Description

Positioning device for front slave plate seat and rear slave plate seat of railway vehicle and assembling method

Technical Field

Background

The working principle of the front slave board seat and the rear slave board seat of the railway vehicle is shown in fig. 1, a traction connecting and hanging device is arranged on a middle beam 2 of the railway vehicle, a coupler 15 receives impact load from a marshalling train in the processes of starting, accelerating, braking and stopping the vehicle, the load is transmitted to a buffer 18 through a coupler yoke 16 and a coupler yoke 17, and the buffer 18 transmits the received load to a front slave board seat 3 and a rear slave board seat 4 through a slave board 19, so that the load is transmitted to the railway vehicle; the positioning of the front slave plate seat 3 and the rear slave plate seat 4 determines the position of the traction coupling device in the length direction of the railway vehicle, and is the key point for ensuring that the clearance between the hook head of the coupler 15 and the impact seat 20 meets the requirement that the coupler 15 and the impact seat 20 do not contact when the railway vehicle makes a limit turn in the running process of the railway vehicle.

From the above analysis, it can be seen that the front and rear punch plate holders act as traction hitch for the railway vehicle. The assembly precision and the quality of the front slave plate seat and the rear slave plate seat directly influence the transmission effect of the load when the railway vehicle runs and the running safety when the railway vehicle turns to the limit.
