Abstract

The present application relates to an air brake auxiliary system for starting on a hill, and relates to the technical field of auto parts. The air brake auxiliary system includes a first integrated control solenoid valve, a differential relay valve and a two-way one-way valve on the rear axle. The first integrated control solenoid valve is connected to the air storage tank and is used to receive the The differential relay valve is respectively connected with the air reservoir and the first integrated control solenoid valve, and is directly connected with the front brake air outlet circuit of the foot brake valve. The differential relay valve It is used to provide air pressure for the brake air chamber at the wheel end of the front axle. The two-way one-way valve of the rear axle is respectively connected with the first integrated control solenoid valve and the rear brake air outlet circuit of the foot brake valve. The check valve is used to supply brake air pressure to the wheel end brake air chamber of the rear axle. The air brake auxiliary system provided by the present application has relatively few connecting elements and a simple pipeline structure, which better reduces the risk of air leakage.

Description

Technical field [0001] The present application relates to a technical field commercial vehicle braking pressure, in particular, relates to an auxiliary air brake system for a hill start. Background technique [0002] With the continuous improvement of people's living standards, more and more popular car in life, hill-start this operation for novice drivers is difficult, at the start ramp, if unskilled driving operation, the vehicle is likely to occur slip Singapore, are particularly vulnerable at this time and the vehicle in front or rear collision caused the accident, therefore, are currently equipped with an auxiliary starting device in the car a lot, in order to solve this problem is difficult hill-start operation. [0003] Starting aid principle is: the driver presses the start button and ramp brakes, when the vehicle hill start, the starting aid is automatically stopped vehicle 1-2 seconds, so that after releasing the brake pedal in the driver, there is enough time to refuel...
