Cross rod end socket for railway wagon x-bracing bogie

Abstract

The invention relates to a cross rod end socket for a railway wagon x-bracing bogie. The cross rod end socket for the railway wagon x-bracing bogie comprises an end socket body, an inner thread bushing, multiple threaded pins and two sealing locks, wherein a blind hole is formed in the large end of the end socket body and multiple through holes are formed in the side wall of the end socket body; the inner thread bushing is of a cylindrical structure and is embedded in the blind hole and multiple threaded holes corresponding to the through holes one to one are formed in the outer wall of the inner thread bushing in the circumferential direction; the threaded pins are respectively of a square-head cylindrical structure, cylinders with threads of the threaded pins penetrate through the through holes in the end socket body and then are screwed in the threaded holes in the inner thread bushing, and a square head of each threaded pin is provided with two locking holes; the two sealing locks respectively penetrate through the locking holes in the same side of the square heads of the threaded pins and lock the threaded pins. The threads of the cross rod end socket are easy to overhaul, part replacement and overhauls can be achieved as well, and the overhaul efficiency is high; in addition, the whole threads can be replaced, the problem that once the threads are damaged, a whole cross rod is scraped is solved, and economic benefits are improved.

Description

technical field [0001] The invention relates to an accessory for a railway freight car, in particular to a cross bar end used for a cross support bogie of a railway freight car. Background technique [0002] The railway freight car cross-braced bogie is the most widely used railway freight car bogie in my country at present. The main parts of the cross-braced bogie are composed of cross bars, which are used to improve the running stability of the bogie. The cross rod is composed of a rod body and two cross rod ends welded; the two cross rods are connected by two splints and bolts in the middle to form a cross rod; the cross rod consists of left and right side frames, rubber elastic pads and anti-loosening sheets, etc. Connected by four bolts, a relatively stable integrated structure of "side frame-cross bar-side frame" is formed. [0003] The structure of the cross bar end mentioned in the above structure is as follows: figure 1 As shown, the large end has a stepped blind ...

AI Technical Summary

Problems solved by technology

During the use of the existing end, thread damage often occurs, and when the cross rod is disassembled and overhauled, the state of the thread in the blind hole is not easy to check. If the thread slip of the end exceeds the allowable limit, the entire cross rod must be scrapped. large economic loss
