Problems solved by technology
[0002] At present, the traditional braking technology uses the hydraulic system to push the brake pads and brake discs to achieve the braking effect of the car; during the braking process, the brake pads as a whole always participate in the friction, and the ring-shaped area of the brake disc and the brake pads is always frictional. No change; such a structure leads to severe local wear of the brake disc, faster overall wear of the brake pad, and increased frequency of replacement of the brake pad, thereby seriously shortening the service life of the brake pad and brake disc, and increasing the maintenance cost of the vehicle

specific Embodiment approach
[0052] Specific embodiments: when the car does not need to brake, the driver does not step on the brake pedal, and the brake pad 20 does not move at the initial position;
[0053]When the car in the driving state brakes normally, the driver lightly steps on the brake pedal; the brake pedal activates the vacuum booster; the vacuum booster controls the operation of the brake master cylinder, so that the hydraulic oil enters the hydraulic cylinder 36 instantly under the action of pressure; The hydraulic oil in the hydraulic cylinder 36 pushes the hydraulic column 35 to slide out of the hydraulic cylinder 36; the hydraulic column 35 drives the worm 29 to rotate through the third connecting block 34, the rack 32, the gear 31 and the second shaft 30; the worm 29 drives the worm wheel 28 to rotate The worm wheel 28 drives the tapered thread drive wheel 26 to rotate through the first shaft 27; the star wheel 23 moves relative to the tapered thread drive wheel 26 along the tapered threa...

The invention belongs to the field of automobile brakes, in particular to an automobile brake caliper, which includes a caliper mechanism, a brake disc, and a wheel shaft, wherein the brake disc is installed on one end of the wheel shaft on the car; the caliper mechanism is fixedly installed on the car body, and the caliper The mechanism cooperates with the brake disc; during the braking process of the car, the contact area between the brake pad and the brake disc increases, so that the friction force per unit area on the friction surface of the brake pad and the brake disc decreases, and the wear of the brake pad and the brake disc It is effectively controlled, thereby prolonging the life of the brake pads and brake discs; during the braking process, while the brake pads are in contact with the brake disc, the side of the second cutout on the balance block is in contact with and rubs against the brake disc, so that both sides of the brake disc The balance of force on the two end faces can avoid the damage of the brake disc due to long-term unilateral force, delay the replacement cycle of the brake disc, and reduce the maintenance cost of the automobile braking system.
