Description
Technical field
The invention belongs to the intermediate emergency relay valve that a kind of self-propelled vehicle drawbar trailer in vehicle braking device technical field coordinates electronics ABS ABS (Anti-lock Braking System) brake equipment.
The intermediate emergency relay valve of ABS ABS (Anti-lock Braking System) brake equipment.
Technical background
Growing along with auto manufacturing and communications and transportation, more and more higher to the technical requirements of automobile-use especially drawbar trailer brake equipment, because it is directly connected to traffic safety.In known technology, when existing self-propelled vehicle drawbar trailer is equipped with ABS anti-lock brake system, be all adopt emergency brake valve as middle brake activation valve.Its effect: the speed-slackening signal of 1 conduction tractor truck; 2 when tractor truck and trailer depart from or loading line disconnects suddenly, to ABS anti-lock brake system speed-slackening signal (braking of namely dying); 3 inflate, for trailer braking protection valve provides propulsion source to the gas receiver of trailer.But, limit by its structure, need mounting and fixing bracket when intermediate emergency relay valve is installed on trailer, because emergency brake valve output interface is four interfaces, also will block its excess-three interface again, its structure is complicated, maintenance frequency is high, especially in structure control plunger top in the winter time easily ponding freeze, cause braking can not, cause the accident or fire, exist install inconvenience, waste resource, time-consuming, bury the undesirable elements such as accident potential.
Summary of the invention
In order to overcome the deficiency of prior art, when solving existing trailer use ABS anti-lock brake system, structure is complicated, installs inconvenience, there is the problems such as accident potential.The invention provides the new-type drawbar trailer brake equipment brake equipment that one is simple and practical, easy for installation, do not use outside necessary resources, saving of work and time, accident free hidden danger.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of intermediate emergency relay valve of motor vehicle trailer, it comprises: comprising: relay valve valve body, piston, air inlet nut, check valve nut, check valve, exhaust nut, pull back spring, check valve linking springs, air inlet nut and check valve nut are housed in one end of relay valve valve body, check valve nut connects check valve, also piston is housed at relay valve valve inner, piston is shaped with five road rectangle grooves, five road rectangle grooves of piston inlay the first-four O RunddichtringO and the 5th O RunddichtringO from left to right successively, the top of piston is also fitted with the 6th O RunddichtringO with connecing check valve nut, the right part shrinkage pool of piston connects check valve built with check valve linking springs, the diameter of the bottom of the right part shrinkage pool of piston and the base apertures of check valve linking springs diminishes and extends to the bottom of pull back spring left, pull back spring is installed between exhaust nut and piston.
Above-mentioned a kind of intermediate emergency relay valve of motor vehicle trailer, described relay valve valve body is shaped with braking input port, brake delivery port, interface of panting, braking delivery port is communicated with the air extractor vent of piston, air inlet nut is shaped with pressurized air input port, exhaust nut is shaped with pressurized air delivery port, is sealed between air inlet nut and relay valve valve body by the 7th O RunddichtringO.
Above-mentioned a kind of intermediate emergency relay valve of motor vehicle trailer, described relay valve valve body left end and exhaust nut by being threaded, outside is shaped with the outside thread be connected with ABS anti-lock brake system.
When the present invention uses, relay valve valve body outside thread is directly connected in ABS anti-lock brake system, pressurized air input port K1 is connected with the inflatable interface of tractor truck, and braking input port K2 is connected with the control interface of tractor truck, and braking delivery port K3 is connected with the control interface of ABS anti-lock brake system.During normal traveling, the pressurized air coming from tractor truck inflatable interface enters pressurized air input port K1, enter inflating cells, check valve is separated with check valve nut, pressurized air enters exhaust chamber, enter piston by braking delivery port K3 through the air extractor vent K6 of piston, pressurized air delivery port K4 enters ABS anti-lock brake system, then enters gas receiver; Run into when vehicle travels need braking time, pressurized air from the pilot piping of tractor truck enters braking chamber by braking input port K2, enter the control interface of ABS anti-lock brake system again through braking delivery port K3, excite the work of ABS anti-lock brake system; When trailer is separated with tractor truck, the pressurized air of inflating cells is got rid of by pressurized air input port K1, connecting line, check valve is under the effect of pressurized air and check valve linking springs, and combine closely with check valve nut, the pressurized air of exhaust chamber is isolated by check valve and inflating cells; Piston moves to right under pull back spring and the compressed-air actuated effect of braking chamber of dying, air extractor vent K6 and the braking delivery port K3 conducting of piston, come from the pressurized air of gas receiver, enter the control interface of ABS anti-lock brake system through air extractor vent K6, the braking delivery port K3 of pipeline, ABS anti-lock brake system, braking input port K2, piston, excite the work of ABS anti-lock brake system; The interface K5 that pants has waste gas to get rid of in this work conversion work.
Because the present invention's design have employed technique scheme, when efficiently solving existing trailer use ABS anti-lock brake system, structure is complicated, installs inconvenience, there is the problems such as accident potential.Also show through testing result on trial for several times, it compared with prior art has simple and practical, easy for installation, do not use outside necessary resources, saving of work and time, the advantages such as accident free hidden danger, are applicable to the drawbar trailer that self-propelled vehicle uses ABS anti-lock brake system.
