Full trailor braking system proposed by the present invention, by trailer gas brake air connector and control joint will control gas circuit,
The compressed air of gas circuit is energized by double relief valve, emergency relay valve, the unidirectional quick release valves of bilateral, ABS combination valve, eventually arrives at system
Take offence room carry out braking maneuver, the functions such as service brake, parking braking, emergency brake are realized with this.It is urgent by matching pressure regulation
Relay valve and 6S6M-ABS system, the harmony that main vehicle and trailer have when can be improved vehicle braking are realized and are adhered in left and right
Controllability on the different road surface of coefficient, while high control precision is mentioned, shorten braking distance, so that vehicle possesses good system
Dynamic performance guarantee traffic safety.
Detailed description of the invention
Fig. 1 is full trailor of embodiment of the present invention braking system schematic diagram；
Fig. 2 is full trailor of embodiment of the present invention braking system service brake gas pressure curve figure.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to tool of the invention
Body embodiment is described in further detail.
The present embodiment proposes that a kind of full trailor braking system, principle are as shown in Figure 1.The formulation system mainly includes trailer
Gas brake air connector 1, trailer gas control for brake connector 2, supply air line 3, control piper 4, brake chamber 5, pressure regulation promptly after
Dynamic valve 6, storage cylinder 7, discharging valve 8, double relief valves 9, ABS combination valve assembly 10 and the unidirectional quick release valve 11 of bilateral.
Go out to be inflated the storage cylinder of trailer by the accumulator tube pass of main vehicle, including is connect by trailer gas braking gas supply
First 1 air inlet enters double relief valves 9 by supply air line 3；Double relief valves 9 are emergency relay valve 6 and two concatenated gas storage simultaneously
Bottle 7 is inflated；Storage cylinder 7 is that three ABS combine the gas supply of valve assembly 10.
The manipulation for carrying out braking maneuver to trailer is drawn by the foot brake valves of main vehicle, including is connect by trailer gas control for brake
First 2 air inlet controls the on-off gas of emergency relay valve 6 by control piper 4；The gas outlet of emergency relay valve 6 and three ABS groups
The air inlet for closing valve assembly 10 is connected, the movement of control ABS combination valve assembly 10, each ABS combination valve assembly 10 and braking gas
The driving chamber of room 5 connects, and controls the service brake of each bridge brake chamber 5；The air inlet of the unidirectional quick release valve 11 of bilateral simultaneously with it is tight
Anxious relay valve 6 is connected with the gas outlet of double relief valves 9, the gas outlet of the unidirectional quick release valve 11 of bilateral and the parking chamber of brake chamber 5
Connection realizes the emergency braking and parking braking of vehicle by the co- controlling of emergency relay valve 6 and double relief valves 9.
In addition, having the discharging valve 8 for discharging water on storage cylinder 7.
The braking system middle rolling car braking system of the present embodiment is double-loop air braking system, due to being normal open for air circuit
Gaseity, no matter vehicle is constantly in inflated condition in traveling or braking to the storage cylinder of double loop trailer brake system, in vehicle
Compressed air also can be supplied timely when lower long slope is continuously braked, and kept braking continuous, reliable, be ensure that the traveling of vehicle
Safety and reliability, this is the major advantage of double-circuit system.
Input and output pressure proportional is controlled by matching pressure regulation emergency relay valve, the trailer braking protection valve reaction time can be optimized to
0.36s is better than laws and regulations requirement (0.4s is not to be exceeded in the time as defined in 12676 standard of GB), as described in Figure 2, can effectively shorten
The lag time of trailer braking protection valve guarantees that retroaction sequence is according to main front axle, extension front axle, master when the movement of complete hang train braking system
Vehicle rear axle, trailer rear axle execute, and vehicle is avoided phenomena such as folding, whipping, rollover occur in braking process.
In addition, ABS anti-lock braking system (i.e. 6 wheels that the braking system in the present embodiment passes through matching 6S6M control mode
Fast sensor, 6 ABS solenoid valves), control one, two, three bridges respectively by wheel speed sensors, therefore each wheel is by individual
One wheel speed sensors and an ABS solenoid valve use modified independent control, not only control precision height, and braking distance is short, and
And vehicle has controllability.
Parking braking system uses spring energy-storage pattern in the braking system of the present embodiment, and spring energy-storage brake chamber relies on
Mechanical spring force is braked to push push rod to generate reliable brake force；In vehicle air pressure deficiency, spring energy-storage gas is indoor
The requirement of vehicle start is not achieved in air pressure, parking can not release, this is just the effect that vehicle makes active protection；Utilize mechanical elastic
Spring force causes vehicle parking to fail to carry out braking without the gas leakage because of vehicle, and vehicle car slipping on ramp is caused to be drawn
Send out safety accident.Therefore, using spring energy-storage brake chamber, reliable brake force, but also its security performance can not only be provided
Might as well, effectively avoid braking system safety failure caused by damage, gas leakage occur while the car is driving.
In the present embodiment, spring brake chamber is respectively mounted in one, two, three bridges and realizes that parking braking, parking braking can also be made
For emergency brake use.Indoor hand brake valve is driven by manipulating main vehicle, parking braking can be implemented to trailer；Simultaneously in trailer
It is upper that double relief valves are housed, can also it implement parking braking to trailer.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
