Description

Technical Field

[0001] This patent relates to the field of caliper disc brakes, specifically an integral fixed caliper disc brake. Background Art

[0002] The caliper disc brake is a type of disc brake. Its rotating element is a metal disc that works on the end surface, called a brake disc. The fixed element is a brake pad composed of a friction block with a small working area and its metal backing plate. There are 2 to 4 brake pads in each brake. These brake pads and their actuators are installed in a clamp-shaped bracket spanning both sides of the brake disc, collectively called a brake caliper. The brake disc and the brake caliper together constitute a caliper disc brake.

[0003] However, when the caliper disc brake in the prior art is braking, the friction plate is severely worn due to the long-term friction between the fixed caliper disc side and the car disc. After the friction plate is worn, the wear cannot be automatically compensated and the friction plate can only be replaced, which seriously affects the service life and braking effect. Therefore, the prior art needs to be improved. Utility Model Content
