The specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described further:
As shown in Figure 1, 2, a kind of integrated ABS anti-lock device of control comprises urgent relay gear 1, and described urgent relay gear 1 comprises admission port 11, exhausr port 12, control mouth 13, air supply opening 14, piston 15, emergency piston 16, valve 17; Described valve 17 both sides are provided with the first air cavity A, and described admission port 11 communicates with the described first air cavity A by check valve; Described air supply opening 14 communicates with the described first air cavity A by an inclined hole a; It is characterized in that: also comprise three electromagnetic control devices 2, controller ECU3, wheel speed sensor; Described controller ECU3 is integrated in the inside, upper end of described urgent relay gear 1, and three electromagnetic control devices 2 are installed in the side of described urgent relay gear 1 respectively, between described electromagnetic control device 2 and the described urgent relay gear 1 the second air cavity B is set;
Described electromagnetic control device 2 comprises valve body 21, electromagnetic valve 22, upper diaphragm 23, following diaphragm 24, loam cake 25, lower cover 26, air extractor duct 27; Described air extractor duct 27 is arranged on the valve body 21, and described loam cake 25, upper diaphragm 23, following diaphragm 24, lower cover 26 are separately positioned on the upper and lower of valve body 21, and described electromagnetic valve 22 is arranged on the lower left quarter of valve body 21, the described second air cavity B bottom; Between the described valve body 21 and the second air cavity B through hole b is set, described valve body 21 is provided with the 3rd air cavity C;
Described controller ECU3 electrically connects with described electromagnetic valve 22, wheel speed sensor respectively.
Principle of work of the present invention and working process are as follows:
As shown in Figure 1, 2, the pressurized air from the tractor-trailer supply air line comes through trailer supply air line gas joint, enters the first air cavity A from admission port 11, and passes through inclined hole a to air supply opening 14, charges into the trailer air receiver respectively.
Glancing impact is from the next pressurized air of tractor-trailer pilot piping, through trailer pilot piping gas joint, act on the top of piston 15 from control mouth 13, piston 15 is moved down, pressurized air from air supply opening 14 through inclined hole a, the first air cavity A, the second air cavity B, to electromagnetic control device 2.Under the effect of the second air cavity B air pressure, move on the upper diaphragm 23, pressurized air through the 3rd air cavity C to air extractor duct 27.
At this moment controller ECU3 judges that according to the vehicle wheel rotational speed signal of wheel speed sensor input the present invention just enters anti-lock brake pressure control process when having wheel to be tending towards locking.When the signal of controller ECU3 according to the wheel speed sensor input, when judging wheel lockup, controller ECU3 outputs to electromagnetic valve 22 with command signal, at this moment electromagnetic valve 22 control upper diaphragms 23 move down, the air pressure of the second air cavity B, the 3rd air cavity C is cut off, air extractor duct 27 brake-pressure decreases, wheel lockup trend will begin to eliminate; When controller ECU3 has eliminated fully according to the locking trend of the signal determining wheel of wheel speed sensor input, just command signal is outputed to electromagnetic valve 22, at this moment move on the electromagnetic valve 22 control upper diaphragms 23, make the pressurized air of the second air cavity B enter the 3rd air cavity C, air extractor duct 27 brake-pressures rise, and wheel leaves again and lifting the rotation of slowing down.The variation of the present invention by the brake-pressure that is tending towards the locking wheel is moved in circles, until car speed be decreased to very low or brake-pressure when no longer making wheel be tending towards locking till.
During brake off, control mouthfuls 13 through the trailer pilot piping by trailer braking protection valve valve outlet 12 exhaust to atmospheres, the air pressure of the second air cavity B makes on the piston 15 and moves to the top, and the air pressure of air extractor duct 27 is through the 3rd air cavity C, upper diaphragm 23, the second air cavity B, valve 17 and exhausr port 12 exhaust to atmospheres.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
