Description

Technical Field

[0001] The utility model belongs to the technical field of brake devices, and in particular relates to a brake pad for a rail transit vehicle. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the braking system of a car. The quality of all braking effects is determined by the brake pads. Brake pads are generally composed of steel plates, adhesive heat insulation layers and friction blocks. The heat insulation layer is composed of non-heat-conducting materials for heat insulation; the friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc and brake drum to generate friction, thereby achieving the purpose of vehicle deceleration and braking.

[0003] The existing rail transit vehicle brake pads still have some defects. During the use of most rail transit vehicle brake pads, the connection between the friction block and the steel back is prone to breakage during long-term use, and the friction structure is damaged, which reduces the braking effect. For this reason, we propose a rail transit vehicle brake pad. Utility Model Content
