Background

The brake is a mechanical brake device which can slow down the speed as the name implies, also called a speed reducer or a brake; briefly, the method comprises the following steps: the automobile brake pedal is arranged below the steering wheel, and when the brake pedal is stepped on, the brake lever is pressed in a linkage manner and is transmitted to the brake block on the brake drum to clamp the brake wheel disc, so that the automobile is decelerated or stops running; the purpose is to decelerate, so as to reduce the speed and also stop the vehicle; the principle of the braking action is to convert the kinetic energy of the vehicle into heat energy to be consumed, and the kinetic energy is from the power provided by the engine.

At present, drum brakes and disc brakes are used as more braking devices, and drum brakes are generally used for large trucks, and have the following problems in use:

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, a brake disc with a larger diameter is required to be used, or the oil pressure of a brake system is increased, so as to increase the braking force;

4. the hand brake device is not easy to install, and a group of drum brake hand brake mechanisms are additionally arranged for the rear wheels of the vehicle using disc brakes;

5. the wear of the brake pad is large, so the replacement frequency may be high.

At present, the brake disc moves oppositely through the brake caliper, so that sliding friction force is generated between the brake disc and the brake caliper, and the aim of reducing speed is fulfilled; the existing brake caliper has the following problems when in use:

1. when the action end of the brake caliper is abutted against a brake disc at present, the contact area between the action end and the brake disc is small, so that the phenomenon of failure is easy to occur, particularly in rainy days;

2. when the effect end of brake caliper was when with the brake disc butt, because its area of contact is little, the rotation inefficiency that leads to can to just also make braking distance great, the security is lower.
