Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a novel floating brake disc. Background Art

[0002] Disc brakes consist of a disc brake disc connected to the wheel and a disc brake caliper on the edge of the disc brake disc. When braking, the brake pad causes the disc brake caliper to clamp the disc brake disc to produce a braking effect. A floating disc brake disc is a type of disc brake disc. Floating disc brake discs are split, mostly including a mounting disc, a brake disc and a floating connector. The floating connector connects the mounting disc and the brake disc together in a floating manner. The mounting disc is fixedly mounted on the wheel hub, and the disc brake caliper can clamp the brake disc to produce a braking effect.

[0003] The existing floating brake disc, such as the floating disc brake disc disclosed in patent number CN 214248088U, is constructed to connect the mounting disc and the brake disc together in a floating manner through a floating connector. However, it is found during use that the floating brake disc is subjected to the impact force of the vehicle's own inertia in the radial direction during braking, which causes the floating connector to loosen after long-term use. After loosening, the brake disc moves within the radial range of the mounting disc. In the long run, the floating connector and the brake disc will fall off, posing a safety hazard.
