Technical Field

Background

The current braking of automobiles is mainly divided into the conventional drum brake and disc brake, wherein the drum brake is still configured on many vehicle models (mostly used for rear wheels) nowadays due to its reliability and strong braking force. It is fixed to the tyre and rotates at the same speed. The brake drum of the drum brake has the following defects that the diameter of the brake drum of the drum brake is increased after being heated, so that the stroke of stepping on a brake pedal is increased, and the brake reaction is easy to occur under the condition that the brake is not as expected. Therefore, when a vehicle adopting drum brake is driven, the heat fading phenomenon of the brake pad caused by high temperature due to continuous braking is avoided as much as possible; 2. the brake system has slow response, the treading force of the brake is not easy to control, and the brake system is not beneficial to doing high-frequency brake action; 3. the structure is complex, parts are more, and the brake clearance needs to be adjusted, so that the maintenance is difficult;

the disc brake mainly utilizes the brake calipers to axially clamp the brake disc to generate braking force, and when the disc brake is stepped, the disc brake clamps the brake disc to play a role in reducing speed or stopping. The brake disc has good braking effect and is easier to maintain than a drum brake; the defect is obvious 1, because the automatic braking function of the drum brake is not available, the braking force of the disc brake is lower than that of the drum brake; 2. the friction area between the brake pad and the brake disc of the disc brake is smaller than that of the drum brake, so that the braking force is smaller; 3. in order to overcome the above-mentioned disadvantages of the disc brake, a large stepping force or oil pressure is required. Therefore, it is necessary to use a brake disc with a larger diameter or increase the oil pressure of the brake system to increase the braking force.
