Specific embodiment
Fig. 1,2,3,4 are a kind of structure charts of commercial car brakes compact back axle brake module.In figure, this commercialization
Car brakes compact back axle brake module includes upper valve body 1 and lower valve body 2, and lower valve body 2 includes piston component, electromagnetic valve
Component and each hermetic unit.Piston component includes the o types circle 4 of piston 3 and the, and the lower end of piston 3 is connected with sealing gasket 17, seals
Pad 17 is contacted with guide pin bushing 19 by compression spring 18, sealed by the 5th o types circle 20, is fixed with jump ring 21.Electromagnetic valve component
Comprising magnetic head 8, air inlet armature set 26, aerofluxuss armature set 25, valve seat 10, the 6th o types circle 22, long compression spring 11 and short pressure
Contracting spring 12, with the break-make of air inlet armature set 26, the control gas circuit of aerofluxuss armature set 25 Stress control is carried out.Upper valve body 1 with
Sealed with the 3rd o types circle 6 between lower valve body 2, fixed by bolt 23.In whole module, have two it is relatively independent, mutually not
The gas channels for communicating, but while realize the mutual balance of two gas circuit air pressure further through piston component and electromagnetic valve component, come
Realize that pressure is adjusted, pressure feed and pressure are discharged.
Control gas air inlet P4 is provided with upper valve body 1, air inlet P1 is provided with lower valve body 2, by the first delivery outlet
P21, the second delivery outlet P22 control back axle or so two wheels end brake simultaneously, and by air vent P3 pressure off-load is carried out.Upper valve
Body 1 and lower valve body 2 are fixed using tap bolt.
Using above-mentioned technical scheme, air inlet P1 is often supply, and when car needs skidding, driver steps on foot valve,
Now controlling gas air inlet P4 has pressure to be input into, and controls the top that gas enters piston 3, to make the position of piston 3 change, piston 3
Lower end compression seal pad 17, the braking gas for making air inlet P1 enters the first delivery outlet P21, the second delivery outlet P22, compression spring 18
React on control gas and keep balance rapidly by the upper and lower side gas of piston 3, make the first delivery outlet P21, the second delivery outlet P22 pressure
Identical with control atmospheric pressure, gas leads to wheel end brake to realize skidding.
When the slip rate that ECU detects car is excessive, made with air inlet armature set 26 by controlling aerofluxuss armature set 25
Braking gas ejects the first delivery outlet P21 of reduction, the second delivery outlet P22 output pressures from air vent P3, so as to reduce brake
Brake force prevent wheel lock up, after slip rate recovers normal, by controlling aerofluxuss armature set 25 and air inlet armature set
26 increase the first delivery outlet P21, the output pressure of the second delivery outlet P22, so as to increase the brake force of brake, realize anti-lock
Function.
When car is started to walk, control gas air inlet P4 no pressure inputs activate ASR valves by ECU, make part braking gas
Into control gas passage, this portion gas is converted into control gas, so as to realize RBT ASR.
This brake module compact conformation, it is only necessary to less arrangement space and beneficial to car load lightweight；It is integrated with additional
Module, such as relay valve and double-way check valve reduce linkage editor, it is to avoid connectivity problem caused by build-up member is excessive, and
Improve work efficiency；Reduce cost；Can integrated ASR, the Premium Features such as HAS, ESP are further cost-effective.
