Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe processing, in particular to a brake shoe fixing structure. Background Art

[0002] Brake shoes are tile-shaped brake blocks made of synthetic materials. When braking, they hold the wheel tread tightly and stop the wheel from rotating through friction. In the train braking system, synthetic brake shoes are one of the key components. The braking force is applied to the synthetic brake shoes through the brake cylinder, so that the friction surface of the synthetic brake shoes contacts the train wheel tread, absorbs kinetic energy, and stops the train. In this process, the braking device converts huge kinetic energy into heat energy and dissipates it into the atmosphere. The groove in the middle of the friction surface of the synthetic brake shoe can realize chip removal and heat dissipation during friction braking. More importantly, it can solve the problem of metal inlay and scratches on the wheel tread that may occur during train braking.
