Problems solved by technology

In the prior art, for example, a brake shoe disclosed in a utility model with the authorized announcement number "CN203477135U" uses riveting to fix the brake shoe and the friction plate. The above fixing method is to ensure the riveting strength. Usually the number of riveting holes is large, which increases the workload of friction plate replacement

Abstract

The invention discloses a brake shoe, which is used to brake a vehicle by friction with a brake drum. The chute can be slidably installed on the shoe body, one end of the shoe body is provided with a positioning baffle, one end of the elastic reset member is connected to the end of the shoe body away from the positioning baffle and the other end is connected to the friction lining and the end away from the positioning baffle; When the friction lining abuts against the positioning baffle, a plurality of cooling holes are provided on the shoe body corresponding to the area of ​​the friction lining, the elastic reset part is always in a compressed state, and the positioning baffle is away from the friction surface between the shoe body and the friction lining Flush, positioning baffles are detachably mounted on the shoe body. In the brake shoe disclosed by the invention, the friction liner is easy to replace and has good heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of vehicle brake equipment, in particular to a brake shoe. Background technique [0002] The vehicle brake is an important part of the vehicle and the key to ensuring driving safety. Vehicle brakes commonly used today include drum brakes and disc brakes. Drum brakes are mainly composed of base plates, brake drums, brake shoes, wheel cylinders, return springs and other components. The brake drum is installed on the wheel hub and rotates with the wheel. When braking, the wheel cylinder piston pushes the brake shoe to press the brake drum, and the brake drum is decelerated by friction, forcing the wheel to stop rotating. Drum brake is a relatively traditional brake, which is widely used because of its cheap price and good braking performance. Among them, the brake shoe is a key component of drum brake. In the prior art, for example, a brake shoe disclosed in a utility model with the authorized announcement n...
