Description

Interlink braking anti-lock brake disc

Technical Field

The invention belongs to the technical field of automobile part production design, and particularly relates to a interlinked braking anti-lock brake disc.

Background

Locking means that when an automobile is braked once in a braking process, tires do not rotate any more, so that the automobile is easily out of control, and traffic accidents and other hazards are caused. Anti-lock, as the name suggests, prevents the automobile from braking once, and adopts intermittent braking. In the prior art, an anti-lock brake system for an automobile tries to convert sliding friction between a wheel and the ground during braking of the automobile into static friction as much as possible (at this time, a contact part between the wheel and the ground is kept relatively static, the automobile is not stopped, the wheel is not locked but rolls, the brake system can apply a brake force on the wheel which is limited to the maximum static friction, and at this time, the static friction between the wheel which keeps rotating and the ground is rolling friction) so as to increase the brake force. However, the basic working principle of the existing ABS anti-lock braking system is to make the brake caliper to perform a "lock-release-lock" cycle on the brake disc until the vehicle stops, in this process, although the vehicle can be prevented from losing control, the vehicle is very easy to brake and bump, which causes discomfort to the driver and passengers.
