Technical Field
The invention relates to the technical field of vehicle braking, in particular to an ABS integrated valve.
Background
With the basic formation of highway backbone networks in China, large-tonnage trucks, cargo-carrying cars, semitrailers and trailers with the obvious cost advantage of ton-kilometers are also increased year by year, and as the wheelbases of the vehicles are increased, the brake pipelines are correspondingly lengthened, so that the reaction time lag and the insufficient brake force of an air brake system are still the main problems for the long-wheelbase vehicles running at high speed.
Due to the fact that a semitrailer is long in body, in the braking process of a main trailer, the semitrailer at the rear end often has the forward rushing condition due to insufficient braking force, and particularly for a novice with low driving skill, if the speed of the semitrailer is too fast, the semitrailer cannot brake immediately after the main trailer treads the brake, and the semitrailer can be braked late, so that the semitrailer can be rushed forward, and traffic faults occur. In order to solve the problems, a conventional method is to install a relay valve in front of a semitrailer integrated valve to play a role in pressurization so as to achieve the effect of emergency braking. However, the booster braking mode has the defects of complex integral structure, troublesome installation and disassembly, low maintenance efficiency due to the fact that the working states of the two valves need to be detected when a fault occurs.
