Braking device and anti-lock braking system

Abstract

The invention belongs to the technical field of automobiles, and discloses a braking device and an anti-lock braking system. The braking device comprises an ABS solenoid valve and a brake air chamber,the ABS solenoid valve comprises an air inlet and an exhaust port, and the air inlet and the exhaust port can be selectively opened and closed; the brake air chamber is arranged on the ABS solenoid valve, a vent is formed in the brake air chamber, and the vent can be respectively communicated with the air inlet and the exhaust port. The braking device forms the brake air chamber integrated with the ABS solenoid valve, has a compact overall structure, and is convenient to install and arrange. The braking response time is greatly reduced, and the braking performance is improved. In addition, when the braking is released, the remaining compressed gas in the braking air chamber can be discharged through the exhaust port at the fastest speed to quickly release the braking, and the decompression process of the ABS solenoid valve and the brake return time are greatly reduced, thereby reducing the rate at which a brake heats up and improving the performance of the ABS solenoid valve.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a braking device and an anti-lock braking system. Background technique [0002] The anti-lock braking system means that when the car brakes, it can automatically adjust the braking force of the brakes so that the wheels are not locked, so as to ensure the maximum adhesion between the wheels and the ground. Antilock braking systems are therefore standard equipment for basic commercial vehicles. [0003] Generally, an anti-lock braking system generally includes an ABS solenoid valve as a core component and a brake chamber as an executive component. The size is adjusted, and the brake air chamber converts the pressure of the compressed air in the air brake system into a mechanical force that makes the brake camshaft rotate, thereby realizing the braking action. In the prior art, the ABS electromagnetic valve and the brake air chamber of the anti-lock braking system are separat...

AI Technical Summary

Problems solved by technology

[0005] First of all, due to the narrow frame of the light truck, there is no room for the ABS solenoid valve, making it difficult to arrange the ABS solenoid valve;

[0006] Secondly, the ABS solenoid valve is far away from the brake air chamber, so that the connecting pipe from the air outlet of the ABS solenoid valve to the air inlet of the brake air chamber is too long, resulting in a long braking response time, which may seriously affect the braking performance;

[0007] Finally, because the exhaust port is too far away, the air brake chamber is discharged too slowly by the compressed air, resulting in a rapid brake temperature rise and a decline in ABS performance
