Description

Technical Field

[0001] This invention relates to the field of rail vehicle technology, and in particular to a bogie end support structure. Background Technology

[0002] Sand spreading devices increase wheel traction on the track, improving vehicle slippage, starting performance, and braking performance. Obstacle removal devices promptly clear obstacles, preventing train derailment. Wheel flange lubrication devices reduce dry friction between the wheel and track, thus saving power, reducing operating noise, and decreasing the frequency of flange and rail replacements, extending wheel life.

[0003] Chinese patent document CN215706275U discloses an installation structure for a sand-spreading, obstacle-removing, and wheel flange lubrication device, and a rail vehicle using the installation structure. The installation structure includes a support arm, a first bracket, and a second bracket. The support arm is fixedly connected to the longitudinal beam of the rail vehicle frame. The lower end of the support arm body is provided with a curved plate, which includes a vertical part and a longitudinal part. The first bracket is connected to the vertical part of the curved plate and can slide vertically relative to the vertical part. The second bracket is connected to the longitudinal part of the curved plate and can slide longitudinally relative to the longitudinal part. The sand-spreading device and the obstacle-removing device are installed on the first bracket, and the wheel flange lubrication device is installed on the second bracket.

[0004] However, the above solution still has the following technical shortcomings: the wheel flange lubrication device is fixed on the second bracket, and the second bracket can only move longitudinally relative to the wheel flange. The vertical and lateral installation positions of the lubrication device depend entirely on the welding and machining accuracy of the boom body and the bending plate. When the wheel wears down and the wheel diameter decreases, it is difficult to adjust the lubrication nozzle to the most suitable position. At the same time, the sand spreading device and the obstacle removal device are installed on the first bracket. The sand spreading device and the obstacle removal device can only move vertically along with the first bracket. Meeting the position requirements of one device may affect the operation of the other device.

[0005] Therefore, there is an urgent need for a bogie end support structure to solve the above-mentioned technical problems. Summary of the Invention
