Problems solved by technology

[0003] Although the existing pneumatic disc brakes can play the role of braking the wheel hub of the car, when the car is on a wet or icy low-friction road, it often causes the tires to lose grip and cause the vehicle to lose control The ability of direction, although in the existing technology, the "ABS anti-lock braking system" has been developed, but after braking, the tires are still in the state of rolling and sliding (the slip rate is about 20%), resulting in the pressure disc There are still certain potential safety hazards when the brake is used. For this reason, we propose an air disc brake

[0034] DETAILED DESCRIPTION: When the wheels are running on a normal ground, the two protective plates 9 are distributed on the outside of the brake disc, and the oil suction pad 29 plays a role of degreasing and dustproofing the brake disc. When the vehicle is freezing When driving on the road and braking, the driver judges the icy road subjectively according to the driving state, and controls the driving motor 16 to rotate through the in-vehicle controller, so that the driving gear 17 drives the driven gear 18 to rotate, and the driving gear 17 performs While rotating, the driving force of the support shaft 19 is provided. The support shaft 19 drives the first support rod 22 to rotate. When the two first support rods 22 rotate at the same time, the second support rod 24 is driven by the connecting shaft 23 respectively. Rotate and push the two protective plates 9 to move in the opposite direction of the brake disc. At the same time, the rotating motor 15 runs, so that the worm...

Abstract

The invention discloses an air pressure disc brake. The air pressure disc brake comprises a brake body, wherein the outer side of the brake body is provided with an equipment damping base capable of removing oil stains on the outer side of a brake disc and used for casting machining, and an auxiliary brake protection device is arranged on the outer side of the brake body; the auxiliary brake protection device is distributed on the outer side of the brake body under the condition that the brake body is normally used, and achieves the effect of removing impurities such as oil stains on the outerside of the brake disc on the outer side of the brake disc, so that the impurities such as the oil stains are prevented from entering a brake pad along with rotation of the brake disc; and meanwhile,when a vehicle is braked on a wet or frozen low-friction road surface, the auxiliary braking protection device can be attached to the ground, the contact friction force between the auxiliary brakingprotection device and the ground is increased, and the effect of stably braking vehicle tires is achieved.

Description

Technical field [0001] The invention relates to the technical field of disc brakes, in particular to pneumatic disc brakes. Background technique [0002] The air disc brake is installed on the wheel shaft and rotates synchronously with the wheel. The disc brake is mainly divided into: bracket and guard, pin shaft, flange, brake disc, brake pad, caliper, when braking, the brake caliper is clamped Brake disc, (fixed between the middle of the brake disc and the wheel), the brake disc and the brake pad contact to produce braking, (that is, the caliper generates braking torque under pressure, and the brake pad is clamped under the push of the piston The brake disc, the brake disc and the wheel decelerate or stop rotating, and the constant friction between the brake pad and the brake disc produces consumption. To ensure the normal braking function, it is necessary to regularly check and replace the contact to generate braking force). [0003] Existing pneumatic disc brakes, although the...
