Multichannel integrated ABS (Anti-lock Brake System) rear axle brake module

Abstract

The invention discloses a multichannel integrated ABS (Anti-lock Brake System) rear axle brake module. The multichannel integrated ABS rear axle brake module integrates an electromagnetic valve and a relay valve, wherein the electromagnetic valve comprises a left electromagnetic valve component and a right electromagnetic valve component which are mounted on the relay valve, and the relay valve is used for maintaining, increasing or reducing pressure through the left electromagnetic valve component and the right electromagnetic valve component. The multichannel integrated ABS rear axle brake module has the advantages that the multichannel integrated ABS rear axle brake module is compact in structure and beneficial to mounting and maintenance; the multichannel integrated ABS rear axle brake module is capable of lightening products effectively, reducing oil consumption and protecting the environment; the quantity of components and parts on an automobile chassis is decreased, and assembly and overhaul are facilitated; system response time can be prolonged effectively due to reduction of middle pipe connection; the left electromagnetic valve component and the right electromagnetic valve component can be detached separately, and accordingly later-period overhaul and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular, the invention relates to a multi-channel integrated ABS rear axle braking module. Background technique [0002] Anti-lock braking system ABS, the full name is Anti-lock Brake System, is a car safety control system that has the advantages of preventing wheel lock, shortening the braking distance of the car, reducing tire wear, and preventing the car from running off and flicking. It works based on the conventional braking system. In the event of a wheel approaching lockup, the corresponding wheel brake pressure is released and held constant during the required or measured reacceleration of the wheel, after which the brake pressure is gradually increased. It is equivalent to a separate "point brake" for each wheel. [0003] The ABS solenoid valve in the prior art has large volume, single function, long system response time, poor safety and reliability. The invention patent with...

AI Technical Summary

Problems solved by technology

In the utility model, two pairs of electrically controlled relay valves that can operate independently are arranged on the main body to form a double-channel air valve, and then the two pairs of electrically controlled relay valves are controlled by the electromagnetic valve group, although it can realize independent pressurization and maintenance pressure, decompression or common pressurization, pressure maintenance and decompression, but it also has problems such as low integration, heavy product weight, long system response time, poor safety and reliability, poor independence and real-time performance, etc.

[0005] Generally speaking, some rear axle braking devices in the prior art generally have problems such as low integration, heavy product weight, long system response time, poor safety and reliability, poor independence and real-time performance, etc. Therefore, a multi-channel integrated ABS rear axle brake module is needed to solve the above-mentioned problems in the prior art, meet the needs of vehicle product integration, light weight, and convenient maintenance and testing, and reduce system response time
