Description

Technical Field

[0001] This patent relates to the technical field of brakes, specifically a lightweight and wear-resistant floating caliper disc brake. Background Art

[0002] The brake is an indispensable part of an automobile. However, current brakes are usually floating caliper disc brakes and fixed caliper disc brakes. In the existing floating caliper disc brake, relative rotation can occur between the brake caliper and the brake disc. The brake caliper is sleeved on a cross bar on the axle through a slip ring. However, the slip ring and the cross bar are in sliding friction, which is prone to jamming over time, and the long-term wear results in a low service life. Moreover, the base plate and the friction lining on the friction block inside the brake caliper are detachably connected for easy replacement of the friction lining. However, they are connected by bolts. When the friction block contacts the rotating brake disc, it is easy to drive the internal bolts of the friction block to rotate, resulting in the detachment of the friction lining.
