Current collector for railway vehicle and railway vehicle

Abstract

The invention discloses a current collector for a railway vehicle and the railway vehicle. The current collector comprises a mounting bracket, a carbon contact strip, a buffer piece, a connecting piece and a matching piece, wherein one end of the mounting bracket is fixed on a vehicle body of the railway vehicle; a mounting hole is formed in the mounting bracket; the carbon contact strip is positioned at the other end of the mounting bracket; the buffer piece is arranged between the carbon contact strip and the mounting bracket; the connecting piece comprises a first rod body and a second rodbody; the first rod body penetrates through the buffer piece; one end of the first rod body is connected with the carbon contact strip; the other end of the first rod body is connected with the secondrod body, the outer diameter of the first rod body is larger than that of the second rod body; and the second rod body penetrates through the mounting hole. According to the current collector, the matching piece is matched with the second rod body to limit the buffer piece, the upper end of the first rod body extends into the mounting hole, the matching piece abuts against the top end of the first rod body, the assembling mode is simple, the assembling efficiency can be improved, and the situation of mistaken assembling can be avoided.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a current collector for rail vehicles and the rail vehicle. Background technique [0002] In the related art, a current collector is provided on the rail vehicle, and the current collector includes a bracket and a carbon slide plate, the carbon slide plate is arranged at the bottom of the support, and a buffer is provided between the carbon slide plate and the bracket to buffer the vibration generated by the carbon slide plate. Among them, since the fixing part and the buffering part are connected flexibly, the buffering part will rotate with the fixing part when the fixing part is tightened, which not only reduces the assembly efficiency of the current collector, but also affects the fastening effect of the fixing part . [0003] In order to solve the above problems, usually a sleeve is pierced in the buffer member, and the fixing member can sequentially pass throug...

AI Technical Summary

Problems solved by technology

However, when the sleeve is installed, it is easy to deflect between the sleeve and the assembly hole on the bracket, resulting in assembly errors, and the sleeve is sandwiched between the bracket and the carbon slide when the fixing member is tightened

When the current collector is charging, the fixing part will slide between the bracket and the carbon slide, which affects the structural firmness of the current collector. The carbon slide is easy to loose, which greatly affects the charging efficiency of the rail vehicle
