This device is integrated and one with above-mentioned functions, has simplified the vehicle pipeline, has made things convenient for installation, has improved the reliability of brake system.
To introduce the principle of work of integrated form ABS regulating control of the present invention below:
This device integrates through the ABS regulating control with traditional relay valve and left and right sides wheel, thereby can realize following function:
Can realize the brake operating of dual mode through integrated form ABS regulating control:
1, conventional brake: do not receive the control command of ECU, realize braking and alleviate according to foot brake valve output pressure size;
2, electric control braking: receive control command, realize electric control braking and alleviation from ECU.
In conventional brake,, be stored in the air feed chamber of this regulating control through air supply opening 28 from the braking pressure of source of the gas air receiver 26 when behind the vehicle launch or when normally exercising.
When foot brake valve 1 is not trampled; This regulating control control chamber is communicated with the foot brake valve outlet through control mouthfuls 27; The gas of each chamber is pressed the motion of direction shown in the accompanying drawing filled arrows direction in the first brake application by spring air chamber 22 and the second brake application by spring air chamber 23 and the regulating control; And pass through this device exhausr port 31 towards atmosphere, this moment, vehicle was in relieved state.
After foot brake valve 1 is trampled;, promote dummy piston 2 and move downward through the control mouth 27 control of access chambeies of this regulating control from the control air pressure of foot brake valve 1, rubber valve 3 is opened; And the control air pressure that is stored in the air feed chamber is moved by direction shown in the accompanying drawing 3 hollow core arrows; Install first and second delivery ports 29,30 through this and get into compressed air brake cylinder 22,23 promotion levers respectively respectively to wheel 24,25 implementation brakings, this moment, vehicle was in braking mode.
After foot brake valve 1 is trampled and is unclamped; The control air pressure of control chamber is arranged to atmosphere from the exhausr port 31 of foot brake valve 1 through control mouthful 27 backs; Simultaneously; Rubber valve 3 is got back to original position under the effect of pull back spring 4, this moment, the braking pressure from source of the gas air receiver 26 was closed in again in the air feed chamber of this regulating control.The gas of each chamber press the direction motion shown in the accompanying drawing filled arrows once more in the first brake application by spring air chamber 22 and the second brake application by spring air chamber 23 and the regulating control, and the exhausr port 31 through this regulating control is towards atmosphere.This moment, vehicle was in the relieved state after the braking.
In the electric control braking process; Wheel speed sensors 20,21 ground in wheel both sides pass to ECU controller 19 with detected wheel speed signal in real time; After wheel speed drops to a certain degree; ECU controller 19 sends different break-make instructions, thereby controls through 14,15,16 and 17 pairs of electromagnetic valves 6,7,10 and 11 of cable, and diaphragm 5,9,8 and 12 is switched between unlatching, closed condition; Make air pressure in the chamber of first, second brake application by spring air chamber 22,23 become big simultaneously or diminish, thereby realize closed loop electric control braking and alleviation.
