Abstract

The invention relates to an air brake auxiliary system for hill starting, and relates to the technical field of automobile accessories. The air brake auxiliary system comprises a first integrated control electromagnetic valve, a differential relay valve and a rear axle two-way one-way valve; the first integrated control electromagnetic valve is connected with an air storage cylinder and used for receiving compressed air in the air storage cylinder, and the differential relay valve is connected with the air storage cylinder and the first integrated control electromagnetic valve, and is directlyconnected with a front brake air outlet circuit of a foot brake valve; the differential relay valve is used for providing air pressure for a front axle wheel end brake air chamber, and a rear axle two-way one-way valve is connected with the first integrated control electromagnetic valve and a rear brake air outlet loop of the foot brake valve; and the rear axle two-way one-way valve is used for providing braking air pressure for a rear axle wheel end braking air chamber. According to the air brake auxiliary system, the number of connecting elements is relatively small, the pipeline structureis simple, and the risk of air leakage is well reduced.

Description

technical field [0001] The present application relates to the technical field of air brakes for commercial vehicles, in particular to an air brake assist system for starting on a hill. Background technique [0002] With the continuous improvement of people's living standards, cars are becoming more and more popular in life. The operation of starting on a slope is relatively difficult for novice drivers. When starting on a slope, if the driving operation is not skilled, the vehicle is likely to slip At this time, it is particularly easy to collide with the rear or front vehicles and cause accidents. Therefore, many cars are equipped with auxiliary starting devices to solve the problem of difficult starting operations on slopes. [0003] The principle of the auxiliary starting device is: the driver presses the hill start button and steps on the brake. When the vehicle starts on a hill, the auxiliary starting device will automatically brake the vehicle for 1-2 seconds, so that ...
