The brake fluid pressure can not change even though the brake clearance changes, so that the brake clearance of the automobile needs to be manually adjusted, and the friction plate also needs to be frequently replaced.
In order to ensure that the adhesive force between a wheel and the ground is at the maximum value, the conventional braking system adopts a 'inching' mode to automatically control the braking force of a brake, so that the wheel is not locked and is in a rolling and sliding state, namely, the anti-lock braking system is a complex hydraulic control system, needs a plurality of hydraulic control pipelines to enable a brake caliper to intermittently contact with a brake disc, is very complex in structure, and is difficult to achieve the optimal anti-lock effect under the condition that the braking clearance cannot be automatically adjusted.

The purpose of the invention can be realized by the following technical scheme: a vehicle braking system with automatic braking clearance compensation is characterized by comprising two braking discs fixedly connected with an automobile hub, a braking body fixed on an automobile frame and a compensating plate fixed on the braking body, wherein the compensating plate is positioned between the two braking discs, and a braking assembly is respectively arranged between the compensating plate and the two braking discs; the brake assembly comprises a brake piston, a compensation pressure plate, a compensation sliding cavity, a brake sliding cavity, a pressure control cavity and a separation spring, the brake piston is connected in the brake sliding cavity in a sliding manner, the compensation piston is connected in the compensation sliding cavity in a sliding manner, the inner end of the brake piston is fixedly provided with a friction plate capable of abutting against the outer side surface of a brake disc, the compensation pressure plate extends between the brake disc and the compensation plate through a connecting rod connected on the compensation piston, hydraulic oil is filled in the compensation sliding cavity and the brake sliding cavity, the compensation sliding cavity and the brake sliding cavity are communicated through an intercommunicating hole, the separation spring abuts against the bottom of the compensation sliding cavity and the outer end of the compensation piston, the separation spring can drive the compensation pressure plate to be far away from the brake disc, and the compensation pressure plate is provided with, a compensation column is connected in the positioning hole in a sliding manner, and the inner end of the compensation column is abutted against the compensation sheet; the circumferential surface of the compensation column is provided with a plurality of inverted tooth-shaped one-way convex ribs at equal intervals, the inner wall of the positioning hole is fixedly provided with a limiting baffle piece which can be inserted into a gap between every two adjacent one-way convex ribs, and the pressure control cavity is connected with an air source or a hydraulic source.
A closed hydraulic circulation cavity is formed among the brake sliding cavity, the compensation sliding cavity and the intercommunicating hole, and the brake piston and the compensation piston can move in opposite directions.
In the prior art, generally, a structure that a spring is directly arranged at a brake piston is adopted, so that a pressure source overcomes the pretightening force of the spring to drive the brake piston to move, and after the pressure source disappears, the restoring force of the spring drives the brake piston to reset, and the direct action mode can shorten the brake reaction time to a certain extent, but the abrasion between abrasion pairs is very serious, so that the high temperature caused by the abrasion can have negative influence on the brake effect. In the braking process, the larger the braking force is, the better the braking effect is, but the maximum adhesive force between the wheels and the ground is ensured, and the slow increase of the braking force is beneficial to the braking effect. Moreover, the buffer effect and the protection effect to the braking piece are better in this scheme.
The one-way convex rib on the compensation column enables the limiting blocking sheet to move mutually in one direction only towards the relative compensation column, namely the compensation column can only be far away from the brake disc.
Measurement of the total amount of wear of the friction pads and the brake disc in a single brake assembly: after wearing, the clearance between the brake disc and the friction plate is increased, in the braking process, as the braking piston is close to the outer side surface of the brake disc from the outer side, the compensation pressure plate is close to the inner side surface of the brake disc from the inner side to the outer side, the difference of the wearing clearance is reacted on the compensation pressure plate, so that the compensation pressure plate presses the inner side surface of the brake disc, the compensation column is pressed to move towards the direction of the compensation plate, after the compensation column moves, the clearance between the compensation pressure plate and the compensation plate is increased, further, the initial position of the compensation piston is relatively retracted, the compensation sliding cavity is communicated with the braking sliding cavity, the braking piston is pushed along with the retraction of the compensation piston under the condition of maintaining pressure balance, even if the clearance between the friction plate at the inner.
Because the liquid is incompressible or the compressed space is small, the retraction of the compensation piston in the process of compensating the clearance is not limited enough by the separation spring, and the minimum pressure at which the pressure control cavity can drive the brake piston to be close to the brake disc is almost unchanged, so that the brake system can still maintain a relatively stable braking initial state after being used for a period of time, and a relatively ideal braking effect is kept between the friction plate and the brake disc under the condition that a braking force input source is constant.
The brake disc has two, and realize the compensation of braking and braking clearance respectively, can improve braking effect, because the braking that causes through the mode of indirect reaction brake power postpones can prolong braking reaction time, setting through two brake discs can compensate this problem to a certain extent, and gapped between two brake discs, do benefit to the heat dissipation, compensating plate and brake piston set up respectively in the brake disc both sides, compress tightly the both sides face of brake disc respectively in braking process, do benefit to braking effect, ensure that the brake disc is steady, and can prevent brake disc deformation to a certain extent, wearing and tearing are irregular etc.
