Description

Technical Field

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

[0002] Brake shoes are accessories that are pushed outward by the action of the brake cam or push rod to press the brake drum to achieve braking effect. They are installed on the brake drum and are one of the key safety parts in the automobile braking system. The brake shoes are shaped like a half-moon. When the brakes are applied, the two half-moon-shaped brake shoes expand outward under the action of the brake wheel cylinder, supporting the brake shoes and rubbing against the inner wall of the brake drum to slow down or stop the car.

[0003] In the existing technology, when the brake shoe is in use, the wear plate will become thinner as it wears. When the wear plate is worn to a certain extent, the brake drum and the metal block will wear, thereby generating noise to remind people to replace the wear plate. However, in the case of wear, the part of the metal block in contact with the brake drum will become thinner, seriously affecting the normal use of the brake shoe, so that the entire brake shoe needs to be replaced, which increases the cost of use and is not convenient to use.
