Description

Technical Field

[0001] The utility model relates to the technical field of rear wheel drum brakes for cars, in particular to a riveted brake shoe assembly for rear wheel drum brakes for cars. Background Art

[0002] The rear wheel drum brake of a car uses a brake transmission mechanism to make the brake shoe press the brake friction plate against the inner side of the brake drum, thereby generating braking force, which slows down the wheel or stops the car in the shortest distance as needed to ensure driving safety and ensure that the car is parked reliably and cannot slide automatically. The drum brake shoes of domestic cars mostly use a welded shoe structure, which not only consumes a lot of energy but also has poor reliability of the products produced. It is often prone to quality problems such as cold welding and insufficient welding force between welded parts, and customers complain about many problems. Utility Model Content
