Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake shoes, in particular to a protective automobile brake shoe. Background Art

[0002] Automobile brake shoes are an important part of the vehicle's braking system, used to convert kinetic energy into heat energy, thereby reducing the vehicle's speed or stopping the vehicle. Brake shoes are usually made of metal materials, such as iron, copper, aluminum, etc., and their surfaces are coated with friction materials to increase the friction between the brake disc or brake drum. During the braking process, the brake shoes will be subjected to the pressure of the brake oil, causing them to be tightly pressed against the brake disc or brake drum, and the vehicle will be slowed down or stopped through friction. As the vehicle's mileage increases, the brake shoes will gradually wear and need to be regularly inspected and replaced. Generally speaking, the service life of automobile brake shoes is about 30,000 to 50,000 kilometers, but actual usage varies due to driving habits, road conditions and other factors. In order to ensure driving safety, it is recommended that car owners regularly check the brake system to ensure that the brake shoes are in good condition.

[0003] Brake shoes are a very important component of a car's braking system. However, traditional brake shoes still have some shortcomings. For example, their heat dissipation capacity is poor. When the car is running, the brake shoes will generate a lot of heat. If not properly managed, they may be damaged and their performance may be reduced, which will pose a hidden danger to driving safety. In addition, the structure of the friction plate is relatively fixed, so it is difficult to replace it when it is damaged, which makes maintenance time-consuming, labor-intensive and inefficient. Therefore, a protective automobile brake shoe is proposed to address the above problems. Utility Model Content
