Power.Chinese invention patent application " trailer " (application number:200810054115.3 publication date:2010.09.08 one) is disclosed
Kind mechanical type inertia braking system is generated the thrust to trailer towing ring, pushes haulage gear backward when being braked using tractor
Movement, while pivoted arm being driven to be allowed to rotate;The pivoted arm other end pull brake cable make brake brake-shoe open and with braking
Drum friction, generates brake force.But the mechanical type inertia brake system efficiency is low, has certain hysteresis quality, is susceptible to
It breaks away, brake coordination is poor, is also easy to produce braking impact.
Fluid pressure type inertial braking system structure is relative complex, as Chinese utility model patent application " has and hits braking work
The trailer fluid power impact braking system of energy " (application number:201120269388.7 publication date:2012.05.09), American invention is special
Profit application " Surge brake actuator " (application number:14/196304, publication date:2015.08.13).Both use
Fluid pressure type inertial braking system.When tractor is braked, speed reduces, and trailer is due to inertia, and instantaneous velocity remains unchanged, and makes
It hits, is moved after causing tractor hook to push trailer towing circumferential direction, in turn at tractor draw hook and trailer towing ring
The push rod of hydraulic main cylinder is hit, impact force is converted into hydraulic coupling and pushes the braking of wheel cylinder by brake piping by push rod
Hoof makes brake.But the braking of this fluid pressure type inertial braking system is insensitive;It is such as braked in turning, easily causes extension
Roof opens the phenomenon that tractor;And fluid pressure type inertia braking is pure mechanic structure, braking characteristic can not be adjusted.
And no matter for above-mentioned mechanical type inertia braking system or fluid pressure type inertial braking system, when tractor is moved backward,
Can inertia impact be caused to trailer, can not moved backward to make trailer generate braking.It is general at present to do to solve the problems, such as this
Method includes:1, it before reversing, with reversing pin by inertia braking device locking, then moves backward again.This method is excessively cumbersome;2、
The brake automatically terminated using reversing braking, such as the Chinese utility model patent application " system of band brake hoof reverse loosing mechanism
Dynamic device " (application number:200820075951.5 publication date:2009.07.01 a kind of small trailer drum brake) is disclosed,
Braking is automatically terminated when reversing, and can restore inertia braking automatically when advancing, and solving inertial braking system trailer cannot
The problem of automatic backing.But this method need to develop brake again, and brake can only be acted in smaller reversing braking moment
Under move backward, can not move backward under steep gradient or severe duty.
In short, problem of the existing technology is:Trailer braking protection valve is insensitive, there is certain hysteresis quality;There is system when reversing
Kinetic moment cannot be satisfied requirement of moving backward under steep gradient or severe duty;Braking characteristic can not be adjusted.

When dynamic, 15 core electric connectors 1 and accumulator 5 are powered to hydraulic system 4 simultaneously.
Working principle of the present invention is as follows:
When tractor is braked, electronic control unit 3 receives tractor brake signal and displacement transducer signal, drives electronic liquid
Press pump 42 and liquid feed valve 46, the high-pressure brake liquid in high pressure accumulator 44 complete trailer system through liquid feed valve 46 to the pressurization of wheel cylinder 49
It is dynamic.
Tractor is braked, and the tractor brake signal output end of 15 core electric connectors 1 exports brake signal to electronic control unit
3, while relative displacement occurring between tractor and trailer, it is slid back and forth between link block 1 and link block 2 23, position
Displacement sensor 24 outputs a signal to electronic control unit 3 after detecting variable quantity, and electronic control unit 3 considers the tractor received
The relative displacement variable quantity signal that brake signal and displacement sensor detect, outputs signal to electronic after internal algorithm calculates
Hydraulic pump 42 and liquid feed valve 46 make liquid feed valve 46 be in "On" state, and the high-pressure brake liquid in high pressure accumulator 44 is through liquid feed valve
46 flow into wheel cylinder 49, push brake-shoe or caliper to be braked, this is pressure process.
When tractor releases braking, electronic control unit 3 receives tractor and releases brake signal, according to displacement transducer signal
Judge whether also to need to brake trailer, liquid feed valve 46 and liquid valve 47 is made to close if also needing to brake trailer
It closes, this is pressure maintaining period;Conversely, electronic control unit 3 drives liquid valve 47, the brake fluid in wheel cylinder 49 to flow back to liquid storage through liquid valve 47
For tank 41 to complete release, trailer releases braking.
Tractor releases braking, and electronic control unit 3 receives tractor and releases brake signal, according to the displacement sensing received
The signal that device 24 exports judges whether also to need to brake trailer, makes liquid feed valve 46 extensive if also needing to brake trailer
Multiple " closing " state, this is pressure maintaining period;Conversely, electronic control unit 3 outputs signal to liquid feed valve 46, liquid valve 47 and electric hydraulic pump
42, so that liquid valve 47 is in "On" state, liquid feed valve is in " closing " state, and electric hydraulic pump 42 is stopped, in wheel cylinder 49
Brake fluid flows back to fluid reservoir 41 through liquid valve 47, this is stress-relief process.
When tractor is moved backward, electronic control unit 3 receives tractor astern signal, is not braked to trailer, until completing
Reversing.
Tractor is moved backward, although displacement sensor 24 detects that variable quantity electronic control unit 3 receives 15 core electric connectors 1
The tractor astern signal of output, trailer will not be braked at this time, until completing reversing.
The present invention uses the structure of tractor brake signal+displacement sensor, when tractor is braked, can examine immediately
Brake signal and displacement transducer signal are measured, and trailer is braked in time.Compared to inertial braking system, tractor is led
Draw after hook and trailer towing ring hit, trailer could trigger braking, the present invention brake it is sensitive, and can greatly reduce by
Trailer caused by braking retardation impacts the braking of tractor, improves the ride comfort in tractor drawbar trailer traveling.And
When avoiding the reversing that inertia braking is brought the problem of triggering braking, the brake without development structure complexity again is to automatic
Release reversing braking.The present invention uses electronic control, and compared to the structure of the full machinery of inertial braking system, braking sensitive, braking can
It leans on and braking characteristic is adjustable.
