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. By means of the characteristics of a four-loop protection valve, the multi-axle trailer braking system is divided into a pluralityof groups of independent two-axle braking systems by using the four-loop protection valve; under the condition that the brake pipeline of any independent group is damaged, only the braking system of the group is influenced and other groups of braking system functions can be still ensured; besides, a parking release control gas circuit is uniformly controlled by using a unique manual parking valve;the manual parking is still controlled only by the unique manual parking valve; an independent parking release air cylinder is also adopted; when an air source fails or other air cylinders leak air and fail, it is guaranteed that the function of relieving parking braking at least once is achieved; the ABS function is further achieved, the braking function has high reliability and stability, tireabrasion is reduced through the self-adaptive capacity of different suspension loads and braking force, and the safety in the driving process is improved.

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 full-trailer car and train brake systems use dual-pipe braking systems, that is, there are two brake pipelines connected to the full-trailer and the tractor, which are used as air supply and service brake control; full-trailer The service brake can be manually controlled by the driver through the pedal or the handle in the tractor cab, while the parking brake must be operated by the driver to perform the parking brake by operating the parking switch valve installed on the full trailer. [0003] The dual-pipe 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 corresponding entire circuit will lose its function due to air leakage and pressure relief, whi...
