Abstract

This utility model relates to the field of brake shoe assembly technology, specifically disclosing an easy-to-assemble brake shoe assembly, including a brake shoe and two symmetrically distributed friction pads that fit against the outer wall of the brake shoe. Two brake shoe ribs are welded to the lower side of the brake shoe. An assembly mechanism is provided between the brake shoe and the two friction pads. The assembly mechanism includes arc-shaped limiting grooves respectively opened on both sides of the brake shoe; limiting posts simultaneously pass through the first and second limiting holes to form a rigid lock, thereby achieving rapid and precise assembly of the friction pads and brake shoes without specialized equipment, significantly reducing assembly costs and improving operational convenience. The arc-shaped limiting plate can be freely removed along the limiting groove, achieving non-destructive disassembly of the friction pads. This method completely avoids the risk of damage to the brake shoe substrate structure caused by traditional destructive removal, ensures the reusability of core components, significantly reduces maintenance costs, and extends the overall service life of the braking system.
