Description

Technical Field

[0001] The utility model belongs to the technical field of brake pads, and in particular relates to a friction block anti-falling type brake pad steel back. Background Art

[0002] In the braking system, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads. During use, the brake pads are in contact and friction with the brake disc or drum to achieve the effect of vehicle deceleration and braking. At present, the existing brake pads generally include steel backs and friction blocks. The steel backs are mainly used to fix friction materials and are easy to install on the brake system. During use, the friction blocks will generate a large force when rubbing against the brake disc. If the relative stability between the steel backs and the friction blocks is poor, the friction blocks may detach from the steel backs, causing accidents, and a lot of noise will be generated when braking.

[0003] Currently, the steel back of brake pads mostly fixes the friction material by means of glue coating or raised structures on the surface. However, in high temperature environments, the glue is easily carbonized, causing the friction material to fall off from the steel back. The raised structures cannot limit the falling of the friction material and cannot provide a stable fixing effect during long-term use.
