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, magnetic valve
Component and each hermetic unit.Piston component includes the o types circle 4 of piston 3 and the first, and the lower end of piston 3 is connected with sealing gasket 17, sealed
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
Include magnetic head 8, air inlet armature set 26, exhaust armature set 25, valve seat 10, the 6th o types circle 22, long compression spring 11 and short pressure
Contracting spring 12, the break-make of gas circuit is controlled to carry out Stress control with air inlet armature set 26, exhaust armature set 25.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 communicated, but the mutual balance of two gas circuit air pressure is realized further through piston component and electromagnetic valve component simultaneously, come
Realize that pressure is adjusted, pressure feed and pressure discharge.
Control gas air inlet P4 is provided with upper valve body 1, air inlet P1 is provided with lower valve body 2, passes through the first delivery outlet
P21, the second delivery outlet P22 control two wheel end brakes of back axle or so simultaneously, and pressure off-load is carried out by exhaust outlet P3.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 control gas air inlet P4 has pressure input, and control gas enters the top of piston 3, the position of piston 3 is changed, piston 3
Lower end compression seal pad 17, air inlet P1 braking gas is set to enter the first delivery outlet P21, the second delivery outlet P22, compression spring 18
React on control gas to keep balancing 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 pressure power, gas leads to wheel end brake to realize skidding.
When ECU detects that the slip rate of car is excessive, by controlling exhaust armature set 25 to make with air inlet armature set 26
Braking gas ejects from exhaust outlet P3 reduces the first delivery outlet P21, the second delivery outlet P22 output pressures, so as to reduce brake
Brake force prevent wheel lock up, after slip rate recovers normal, pass through and control exhaust armature set 25 and air inlet armature set
26 the first delivery outlet P21 of increase, the second delivery outlet P22 output pressure, 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, ASR valves are activated 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 is compact-sized, it is only necessary to less arrangement space and the lightweight for being beneficial to vehicle；It is integrated with additional
Module, such as relay valve and double-way check valve, reduce linkage editor, avoid build-up member excessively caused connectivity problem, and
Improve operating efficiency；Reduce cost；The Premium Features such as ASR, HAS, ESP can be integrated, it is further cost-effective.
