Traditional relay valve is that driver steps on foot brake valves 46 with the work process of ABS electromagnetic valve, air pressure foot brake valves 46 enters relay valve and controls mouth epicoele and promote piston to move down, and pushes valve open and make the air pressure of gas receiver 47 prepare output pressure through the delivery outlet of relay valve to the air inlet of air inlet ABS electromagnetic valve from air inlet 1 mouthful.Air pressure needs, by inner passage, aerofluxus diaphragm epicoele is set up pressure and blocks the valve at aerofluxus diaphragm simultaneously, and otherwise the air pressure of the delivery outlet of electromagnetic valve can enter air by the valve port at aerofluxus diaphragm, cannot set up air pressure.And set up pressure to aerofluxus diaphragm epicoele and be to carry out at the same time point of same chamber to delivery outlet output pressure, so air pressure disperses a little energy, air pressure can have an air pressure to air vent before aerofluxus diaphragm is closed, cause to brake chamber output pressure is slow, finally makes the braking distance of wheel widen.Same problem, when pressurize diaphragm works, ECU pressurize instruction received by electromagnetic valve, now the delivery outlet of electromagnetic valve has operating air pressure, also because the work chamber of air pressure when pressurize diaphragm epicoele builds pressure and electromagnetic valve delivery outlet is identical, also there is a phenomenon that air pressure energy is not enough, cause pressurize diaphragm to be closed the slowest, close front portion gas valve port at pressurize diaphragm at pressurize diaphragm and flow to brake chamber, easily cause brake locking phenomenon.And multichannel integrated form ABS back axle brake unit of the present utility model, it is possible to solving the problems referred to above, the measure taked is before air pressure arrives ABS electromagnetic valve delivery outlet, closes aerofluxus diaphragm in advance.And accept ECU instruction subsequently to air inlet diaphragm, the closedown of aerofluxus diaphragm air inlet " point is stopped " formula.
Multichannel integrated form ABS back axle brake unit of the present utility model, its conventional brake control process: pressurization stages: the work of the electromagnetic valve at two ends all no powers, the pressurization stages in suitable abs braking system in conventional brake.Air pressure leads to first electromagnetic valve in left side and controls end 61.1, second electromagnetic valve in left side controls end 61.2, the electromagnetic valve Passage Route that 3rd electromagnetic valve in left side controls corresponding to end 61.3 is: driver steps on foot brake valves 46, air pressure enters relay valve control mouth epicoele (piston 8 epicoele) from foot brake valves 46 and flows to the second static iron core assembly 26 of the first electromagnetic valve 44, second side opening moving core assembly 27 side, the epicoele being arrived first exhaust diaphragm 2 by inner passage produces pressure to first exhaust diaphragm 2, produced pressure acts on first exhaust diaphragm stage clip 1 simultaneously, valve port at first exhaust diaphragm 2 is entered sealing, and (first exhaust diaphragm stage clip 1 pressure is less, the pressure of self can not seal).Meanwhile, the air pressure of piston 8 epicoele rests on position at the first air intake valve 19 (the pressurize action for deceleration of electrons is prepared) under the second air inlet spring 20, the first effect moving core assembly 21.Aerofluxus diaphragm epicoele set up pressure time simultaneously (link now is extremely important, aerofluxus diaphragm closes the valve port of correspondence in advance), piston 8 moves down and overcomes the pressure of compression spring 12 and open valve 10, air inlet 101 is made to flow to the cavity of resorption B district of piston 8 from the passage that valve 10 is opened from the air pressure of gas receiver 47, back down the first air inlet diaphragm 4(now the first air inlet diaphragm 4 epicoele without air pressure) and the first air inlet film flat spring 5 make air pressure arrive C1 district, air pressure also arrives at D1 district simultaneously and rests on the cavity of resorption of first exhaust diaphragm 2 (inner passage, C1 with D1 district communicates, C1 directly corresponding delivery outlet 211, D1 directly corresponding delivery outlet 231).Air pressure is directly output to delivery outlet 211 and delivery outlet 231, delivery outlet 211 and the mutual UNICOM of delivery outlet 231 simultaneously, and the air pressure of delivery outlet exports brake chamber and provides brake pressure to brake.Because the valve port at first exhaust diaphragm 2 is closed the most in advance, so the operating pressure that C1 district, C2 district export to delivery outlet will not be lost by the valve at first exhaust diaphragm 2.Stable brake pressure is provided to make to ensure for brake chamber.It is above the course of action of left side electromagnetic valve conventional brake.
Right side electromagnetic valve conventional brake process is with identical, and the most corresponding dynamic core assembly, static iron core assembly, diaphragm etc. are on the right side of relay valve, and delivery outlet 211, delivery outlet 231 have changed delivery outlet 221, delivery outlet 241 into.
Multichannel integrated form ABS back axle brake unit of the present utility model, its deceleration of electrons is reduced pressure during controlling, packing stage:
Because the principle of deceleration of electrons is: at wheel close in the case of locking, corresponding wheel brake pressure will be released and keep constant requiring or record during wheel accelerating again, after again accelerating, it is stepped up brake pressure.Be equivalent to each wheel individually " point is stopped ".
Decompression phase: the delivery outlet 211 when system is in pressurization stages, the pressure that delivery outlet 231 exports to brake chamber makes wheel close in the case of locking during brake, ECU can control end 61.1 by the wheel speed sensors rate signal of corresponding wheel the first electromagnetic valve to the left, second electromagnetic valve in left side controls end 61.2 and controls to send depression signal, first electromagnetic valve in left side controls end 61.1, the second electromagnetic valve control end 61.2 in left side switches on power and makes solenoid produce electricity suction, second moves core assembly 27 overcomes the pressure of second exhaust spring 24 to be drawn to the second static iron core assembly 26, the passage simultaneously opening first exhaust valve 25 will be blocked by the passage of the second static iron core assembly 26.The air pressure of first exhaust diaphragm 2 epicoele is flowed to discharge chamber by first exhaust valve 25 and enters air, relay valve delivery outlet C1 district, the air pressure in D1 district back down first exhaust diaphragm 2, the pressure of brake chamber is arranged to air by the valve at delivery outlet 211, delivery outlet 231, first exhaust diaphragm 2, completes work of reducing pressure.
nullPacking stage: meet the requirements when recording vehicle wheel rotational speed and need to keep constant,ECU can control end 61.2 by the second electromagnetic valve to the left、3rd electromagnetic valve in left side controls end 61.3 and sends pressurize signal,Second electromagnetic valve in left side controls end 61.2、The 3rd electromagnetic valve control end 61.3 in left side switches on power and makes solenoid produce electricity suction,First moves core assembly 21 overcomes the pressure of the first air inlet spring 20 to be drawn to the first static iron core assembly 22,The passage of the first static iron core assembly 22 is blocked the passage simultaneously opening the first air intake valve 19,The air pressure arriving piston 8 epicoele from foot brake valves 46 is made to build pressure by the passage of air intake valve 19 at the epicoele of the first air inlet diaphragm 4,The valve closing at diaphragm by entering together with air inlet film flat spring,The air pressure making piston 8 cavity of resorption B district can not pass through this valve conveying air pressure to electromagnetic valve delivery outlet,Complete pressurize work.The pressurize action of above air inlet diaphragm, the decompression action of aerofluxus diaphragm, be all the rate signal sent to ECU according to wheel wheel speed sensors, and ECU sends corresponding action command, to complete ABS electric brake action to the corresponding controling end of electromagnetic valve after processing.
After brake process terminates, driver discharges foot brake valves 46, and the air pressure of piston 8 epicoele enters air by the air vent of foot valve, makes air pressure reduce rapidly to such an extent as to is not enough to overcome the pressure of compression spring 12.This promotes valve 10 of living to be blocked by the valve port of gland 11 under the pressure of compression spring 12, and the air pressure of gas receiver 47 can not enter delivery outlet.This enters delivery outlet C1 district, the air pressure in C2 district backs down first air inlet diaphragm the 4, second air inlet diaphragm 13 respectively, discharges from discharge chamber through B district, and braking procedure terminates.
Either increase stage, packing stage and decompression phase, the relay valve that air pressure needed for two ends electromagnetic valve, two air inlet diaphragms and two aerofluxus diaphragm inner passages is all controlled by foot valve at work controls the epicoele of piston 8 inside mouth to be provided, (this is also one of in place of the difference controlled ABS electromagnetic valve supply with tradition " relay valve with ABS electromagnetic valve ", and this utility model is to be controlled ABS electromagnetic valve and air inlet diaphragm, exhaust membrane by controlling mouth 401;In tradition " relay valve and ABS electromagnetic valve ", the control to ABS electromagnetic valve and air inlet diaphragm, aerofluxus diaphragm is that the delivery outlet by relay valve controls rather than controls mouth 401.The air-path interface controlling mouth 401 is the fast interfaces in VOSS230M16 × 1.5, and the smallest passage diameter of this interface is Φ 5mm.The minimum passage aperture of whole gas circuit be the aperture of first air intake valve the 19, second air intake valve 28 be Φ 1.5mm, first exhaust valve 25, the aperture of second exhaust valve 28 are Φ 2.0mm.Through air intake valve, drain tap lead to air inlet diaphragm epicoele, aerofluxus diaphragm epicoele whole channel volume the least, so can ensure to greatest extent through air intake valve, drain tap epicoele build the pressure time.And carry out being energized with the handoff procedure discharged at dynamic core assembly, through air pressure fluctuation produced by Φ 1.5mm and Φ 2.0mm, can be supplemented timely by the Large Copacity air pressure arriving relay valve control mouth 401 a diameter of Φ 5mm through foot brake valves 46.Through the experiment of this utility model product is detected, verifies that this fluctuation has no effect, static characteristic controls the unlatching pressure also free of losses of mouth.
The screw thread of air inlet 101 and delivery outlet uses the fast interface of VOSS230M22 × 1.5, and the fast passage aisle aperture of this interface is Φ 10mm.In order to increase the gas flow of air inlet and output, the aperture, main channel of Φ 7mm in former ABS electromagnetic valve is re-designed as the passage aperture of Φ 10mm, adds pipe-line system flow.
