Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail vehicle braking technology, and in particular to a universal brake shoe carrier. BACKGROUND

[0002] The brake shoe carrier is a key component of the tread brake of a rail vehicle, and is used to mount and fix the brake shoe. During braking, the tread brake presses the brake shoe against the wheel, and the braking friction torque generated by the friction between the brake shoe and the wheel is used to slow down and stop the train.

[0003] At present, urban rail vehicles, freight cars and high-power locomotives generally use tread braking, so tread braking is the most important form of braking for rail vehicles, and brake shoes and brake shoe carriers are widely used. Because the speed, axle load and line conditions of vehicles are different, the requirements for brake shoes are also different, and brake shoe manufacturers will design and produce specific brake shoes according to specific requirements, resulting in different installation and fixing methods for brake shoes and brake shoe carriers. The most commonly used installation and fixing method is to fix the brake shoe with a brake shoe pin, that is, the brake shoe is fixed on the brake shoe carrier by a brake shoe pin. However, even if they are fixed by brake shoe pins, the dimensions of the brake shoes produced by different manufacturers and the dimensions of the interfaces between the brake shoes and the brake shoe carriers are different, which results in the need for the tread brake manufacturer to redesign and produce brake shoe carriers according to the dimensions of the brake shoes in order to match the brake shoes, thereby increasing the production cost of the tread brake manufacturer and being not conducive to the maintenance of the owner.

[0004] Therefore, it is necessary to provide a universal brake shoe carrier structure that can adapt to various brake shoes with different interface dimensions. SUMMARY
