Problems solved by technology

[0004] In the above-mentioned retaining key structure, the fixing between the retaining key body and the side frame relies on the threaded connection between the bolt and the nut, the position of the retaining key is relatively low from the ground, and the installation and fixing of the nut is time-consuming and laborious, which makes the installation and operation of the retaining key very inconvenient; at the same time, the nut When the vehicle is driving, it is easy to loosen due to the vibration of the vehicle, which not only causes a lot of noise, but also makes the vehicle a potential safety hazard.

Abstract

The invention discloses a stop key device, a railway truck and a bogie thereof. The stop key device comprises a stop key body, a bolt and a pin; the stop key body comprises a stopping portion, a first connecting portion and a second connecting portion, the stopping portion is used for stopping a wheel set from being separated from the bogie, the first connecting portion and the second connecting portion are used for being connected with a side bracket guide frame of a side bracket, the first connecting portion is provided with a first through hole corresponding to a through hole on the side bracket guide frame, and the second connecting portion and the first connecting portion form a U-shaped clamp groove capable of being clamped on the side bracket guide frame; the bolt is penetratingly arranged in the first through hole, and a pin hole is arranged at the tail of the bolt; and the pin is penetratingly arranged in the pin hole. The stop key device, the railway truck and the bogie thereof have the advantages that installation operation for a stop key on the bogie of the railway truck can be simplified, and work efficiency can be improved.

Description

technical field [0001] The invention relates to the technology of a railway freight car bogie, in particular to a retaining key device, a railway freight car bogie and a railway freight car. Background technique [0002] The railway freight car bogie is one of the important parts of the railway freight car. The bogie of the three-piece structure includes a side frame, a bolster and a wheel set. The two ends of the side frame are clamped on the bearings of the wheel set through the side frame pedestal. , When a derailment accident occurs when the steering frame is hoisted or the vehicle is derailed, the side frame pedestal is easily separated from the wheel set bearing, thereby causing the wheel set to be separated from the bogie. In order to prevent the wheelset from detaching from the bogie, a stop key is usually installed in the pedestal of the side frame. When the bogie is under tension, the side frame and the wheel set can be connected together by means of the stop key t...
