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.

Disclosure of Invention

The technical problem to be solved by the invention is to provide an ABS integrated valve aiming at the defects of the prior art, and effectively solve the problem of potential safety hazard caused by the forward rush when the existing semitrailer brakes.

In order to achieve the purpose, the invention provides the following technical scheme: an ABS integrated valve, includes the valve body, its characterized in that: the inside cavity that is equipped with of valve body, the cavity middle part is equipped with the division board that divides the cavity average into two left cavities and right cavities that the volume equals, still be equipped with air inlet, gas vent, gas outlet, solenoid valve and piston assembly on the valve body, piston assembly includes the cylinder head of opening connection about with the cavity, gas vent and cavity intercommunication, be equipped with complex piston sleeve with it in the cylinder head, the piston sleeve includes sleeve and loop bar, telescopic diameter is greater than the diameter of loop bar, still be equipped with the air cage device in the piston assembly, the air cage device is including the air cage body, this internal in-connection of air cage has the air cage endotheca.

The invention further comprises the following steps: the cylinder cover is characterized in that a through hole is formed in the middle of the sleeve, a guide rod matched with the through hole is arranged in the through hole, the guide rod is fixed in the middle of the lower end of the cylinder cover, a cylindrical contact section is arranged on the upper portion of the sleeve, a sleeve connecting piece is arranged on the lower portion of the sleeve, a sleeve rod is arranged in the middle of the sleeve connecting piece, and the diameter of the sleeve rod is smaller than that of the contact section.

The invention further comprises the following steps: the sleeve has a diameter greater than the diameter of the contact section.

The invention further comprises the following steps: the valve body bottom is equipped with the solenoid valve and connects, connect including setting up the connection package material on the valve body, the high strength joint who is connected with the solenoid valve, set up the coupling groove on connecting the package material, set up the coupling bead in the high strength joint periphery and set up the step arch in the coupling bead lower part, coupling groove is the echelonment.

The invention further comprises the following steps: the thickness of the connecting wrapping material is larger than the height of the connecting protrusion.

The invention further comprises the following steps: the connecting groove comprises an upper part and a lower part, the upper part is the same as the connecting bulge structure, and the lower part is the same as the step bulge structure.

The invention further comprises the following steps: a filter screen is arranged in the air inlet.

The invention further comprises the following steps: the number of the exhaust ports is four, and the exhaust ports are all arranged on the upper end face of the cavity.

The present invention having the above features: the cross section area of the piston sleeve is larger than that of the loop bar by adjusting the piston assembly, when braking, airflow enters the piston assembly from the air inlet and reaches a position between the cylinder cover and the piston sleeve, and because the cross section area of the sleeve of the piston sleeve is larger than that of the loop bar, airflow with certain pressure acts on the piston sleeve and is conducted to the loop bar to act downwards, the pressure is increased, the generated braking force is increased, the trailer is braked by strong pressure, the risk of forward rush of the trailer is reduced, and the braking effect of the ABS integrated valve is improved; the filter screen is arranged on the air inlet, so that impurities in the air can be filtered, and the impurities are prevented from entering the valve body to cause abrasion and clamping stagnation on internal parts.
