Problems solved by technology
There are two types of brake pads commonly used now: powder metallurgy materials and synthetic materials. Synthetic materials are not suitable for the braking requirements of high-speed trains due to their low strength, poor heat resistance, and severe thermal decay. On the friction surface, some of the brake pads do not have good heat dissipation performance to ensure that the converted heat energy is dissipated in time, resulting in overheating of the brake pads and causing the failure of the brake disc. For this reason, we have designed a powder metallurgy brake for high-speed trains. piece to solve the above problems

The invention discloses a power metallurgy brake lining for a high speed train. The power metallurgy brake lining comprises an assembly backboard, mounting holes are formed in the two sides of the assembly backboard in a mirror mode, eleven mounting holes are formed in each side of the assembly backboard, annular limiting blocks are arranged inside the mounting holes, grinding blocks are installedinside the mounting holes and are made from a power metallurgy friction material, gaps are formed between every two grinding blocks, round gaskets are arranged between the grinding blocks and the limiting blocks, and the bottoms of the grinding blocks extend to the insides of the mounting holes and penetrate through the backboard to be connected with clamping springs. The power metallurgy brake lining is simple in overall structure, through the shape and the arrangement mode of the grinding blocks, in a work state, it can be guaranteed that the brake lining has the largest friction area, goodcooling conditions ensure that a basic brake of the train safely runs, the grinding blocks can be detached and replaced, and the cost can be effectively lowered.
Description
technical field [0001] The invention relates to the field of brake pads, in particular to a powder metallurgy brake pad for high-speed trains. Background technique [0002] China's rail transit technology is becoming more and more developed, and the number of high-speed rail and bullet trains used in the market is also increasing. Brake pads are key components and consumable parts of high-speed train braking systems. There are two types of brake pads commonly used now: powder metallurgy materials and synthetic materials. Synthetic materials are not suitable for the braking requirements of high-speed trains due to their low strength, poor heat resistance, and severe thermal decay. On the friction surface, some of the brake pads do not have good heat dissipation performance to ensure that the converted heat energy is dissipated in time, resulting in overheating of the brake pads and causing the failure of the brake disc. For this reason, we have designed a powder metallurgy b...
