Description

Technical Field

[0001] The utility model relates to the technical field of automobile air brake valve assemblies, in particular to an automobile air brake valve assembly which can effectively reduce wear. Background Art

[0002] The automobile air brake valve assembly is an important part of the automobile air brake system. It is responsible for controlling the on-off of the brake air circuit and regulating the air pressure, thereby realizing the braking control of the automobile. The exhaust brake valve is used as an auxiliary braking device to reduce the frequency of use of the main brake under conditions such as the automobile going down a long slope, reduce the risk of excessive brake temperature, prevent the braking force from fading, extend the brake life, and reduce the driver's fatigue. The exhaust brake produces a braking effect by compressing the gas in the engine and exhaust pipe. The braking is soft and impact-free, reducing the impact load of the parts, extending the service life of related parts, and has a certain fuel-saving effect.

[0003] When the driver steps on the brake pedal, the pull rod is stretched to make one end of the pull arm press down the balance spring, so that the balance arm moves down, the exhaust valve is closed first, and the intake valve is opened. At this time, the compressed air in the air reservoir is filled into the brake air chamber through the intake valve, pushing the air chamber diaphragm to rotate the brake cam, thereby achieving wheel braking.

[0004] The automobile air brake valve assembly rotates through an axle pin, and the axle pin of the automobile air brake valve assembly is directly connected to the installation position, so that during the braking process of the automobile air brake valve assembly, the axle pin is subjected to a large impact force, and thus wears quickly. During the movement process, the axle pin is constantly rotating, and the friction force on the axle pin is relatively large, which accelerates the wear of the axle pin and greatly shortens the service life of the axle pin and the automobile air brake valve. Based on the above problems, the present application proposes an automobile air brake valve assembly that can effectively reduce wear. Utility Model Content
