Problems solved by technology

Generally, full trailers do not have an ABS anti-lock braking system. During the braking process with the maximum braking force, it is very easy to lock up, which will cause the danger of folding and instability of the whole vehicle train.

Abstract

The invention discloses a grouped multi-axle trailer braking system, wherein, utilizing the characteristics of the four-circuit protection valve, the multi-axis trailer braking system is divided into multiple groups of independent 2-axis braking systems using the four-circuit protection valve. If an independent part of the brake pipeline is damaged, only the braking system of this group is affected, and the functions of other braking systems can still guarantee the braking function. In addition, the only manual parking valve is used to uniformly control the parking release control air circuit, so that Manual parking is still only controlled by the only manual parking valve, and an independent parking release air storage tank is also used. When the air source fails or other air storage tanks fail, it is guaranteed to have the function of releasing the parking brake at least once. With ABS anti-lock function, the braking function has strong reliability and stability, and the adaptive ability of different suspension loads and braking force reduces tire wear and improves the safety during driving.

Description

technical field [0001] The invention relates to the technical field of vehicle braking systems, in particular to a grouped multi-axle trailer braking system. Background technique [0002] At this stage, most of the train brake systems of trailers use dual-pipeline brake systems, that is, there are two brake pipelines connected between the trailer and the tractor, which are used for air supply and service brake control respectively; The service brake can be manually controlled by the driver through the pedal or handle in the cab of the tractor, while the parking brake must be operated by the driver to operate the parking switch valve installed on the trailer for parking brake. [0003] The dual-pipeline braking system guarantees the reliability of the braking system to a certain extent, but once the air supply pipeline or the service brake control pipeline is damaged, the braking system will lose its function due to air leakage and pressure release in the corresponding entire...
