The specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described further:
As shown in Figure 1, 2, the integrated ABS anti-lock device of a kind of axle control comprises urgent relay gear 1, and described urgent relay gear 1 comprises admission port 11, exhausr port 12, controls 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 described the first air cavity A by check valve; Described air supply opening 14 communicates with described the 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 arranged on respectively the side of described urgent relay gear 1, between described electromagnetic control device 2 and described urgent relay gear 1, the second air cavity B are set;
Described electromagnetic control device 2 comprises valve body 21, electromagnetic valve 22, upper diaphragm 23, lower diaphragm 24, upper cover 25, lower cover 26, air extractor duct 27; Described air extractor duct 27 is arranged on valve body 21, and described upper cover 25, upper diaphragm 23, lower 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, described the second air cavity B bottom; Between described valve body 21 and the second air cavity B, a through hole b is set, is provided with the 3rd air cavity C on described valve body 21;
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, is filled with respectively the trailer air receiver.
During braking, from the next pressurized air of tractor-trailer pilot piping, through trailer pilot piping gas joint, act on the top of piston 15 from controlling mouth 13, piston 15 is moved down, and pressurized air is 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 upper diaphragm 23, pressurized air through the 3rd air cavity C to air extractor duct 27.
This Time Controller ECU3 is according to the vehicle wheel rotational speed signal of wheel speed sensor input, and when being determined with wheel and being tending towards locking, the present invention just enters anti-lock brake pressure control process.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-pressures descend, and 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 electromagnetic valve 22 is controlled on upper diaphragm 23 and is moved, 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 is decreased to very low or brake-pressure when no longer making wheel be tending towards locking till.
During brake off, control mouth 13 and enter atmosphere through the trailer pilot piping by trailer braking protection valve valve outlet 12, the air pressure of the second air cavity B makes on piston 15 and moves to the top, and the air pressure of air extractor duct 27 enters atmosphere through the 3rd air cavity C, upper diaphragm 23, the second air cavity B, valve 17 and exhausr port 12.
The above is only preferred embodiment of the present invention, is not to be the present invention to be done the restriction of 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 does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
