In example, it is ability that electronic control unit, which is the electronic control unit of ABS (Anti-lock Brake System, anti-blocking brake system),
The well-known technique in domain, details are not described herein.
In the present embodiment, there are two above-mentioned rear axle spring brake chamber parking chamber interfaces 22.
In the present embodiment, there are two above-mentioned ABS solenoid valves 4, rear axle spring brake chamber is driven a vehicle there are two chamber interfaces 43.
As shown in Figure 1, hand brake valve interface 11, control mouth 32, gas receiver interface 31 and exhaust outlet 5 are successively arranged from top to bottom
Cloth.
The working principle of the combination valve is as follows:
Release parking braking: the compressed air to come from hand brake valve enters hand brake valve interface 11, under pressure
The valve of double-way check valve A1 moves down, and compressed air enters the air inlet II 21 of double-way check valve B2 from gas outlet I 13, and
Enter spring brake chamber parking chamber by rear axle spring brake chamber parking chamber interface 22, compress brake chamber spring, realizes
Parking braking releases.
Parking braking: hand brake valve does not have compressed air to come, after the compressed air warp of spring brake chamber parking chamber
Bridge spring brake chamber parking chamber interface 22, gas outlet II 23 and exhaust outlet 5, are discharged to atmosphere, and brake chamber spring is released,
Realize parking braking.
Service brake: when foot brake valves are stepped on, compressed air bridge loop gas outlet after foot brake valves enters control mouth 32,
The piston of relay valve 3 moves down, and the compressed air entered from gas receiver interface 31 is by entering two position two-way valve I behind gas outlet III 33
41 air inlet III 411 enters rear axle spring brake chamber driving chamber interface 43 from working hole I 412, enters back into spring braking gas
Room driving chamber, realizes service brake.
Pressure maintaining: in service braking operation, when needing to keep brake pressure according to the judgement brake circuit of ABS electronic control unit,
Two position two-way valve I 41 it is electric, make two position two-way valve I 41 be in cutting position, keep spring brake chamber driving chamber in pressure.
Decompression: in service braking operation, when needing to reduce brake pressure according to the judgement brake circuit of ABS electronic control unit,
Two position two-way valve II 42 it is electric, make two position two-way valve II 42 be in connect position, spring brake chamber drive a vehicle chamber in pressure pass through
Rear axle spring brake chamber driving chamber interface 43, working hole II 421, gas outlet IV 422 and exhaust outlet 5, are discharged to atmosphere, realization subtracts
Small brake pressure.
Anti- parking and service brake superposition: under parking braking state, hand brake valve interface 11 does not come from hand brake valve
Compressed air, brake chamber spring is released, and vehicle is in parking braking state.Foot brake valves are stepped at this time, and compression is empty
Gas enters from control mouth 32, and the piston of relay valve 3 moves down, and the compressed air entered from gas receiver interface 31 passes through gas outlet III 33
The air inlet III 411 for entering two position two-way valve I 41 afterwards enters rear axle spring brake chamber driving chamber interface from working hole I 412
43, spring brake chamber driving chamber is entered back into, realizes service brake.The compressed air for entering control mouth 32 simultaneously enters air inlet
I 12, it touches piston and moves up, compressed air enters the air inlet II 21 of double-way check valve B2 behind opening gas outlet I 13, then
Piston is pushed to move down, compressed air enters spring brake chamber parking chamber, pressure from rear axle spring brake chamber parking chamber interface 22
Contracting brake chamber spring, parking braking are released, namely realizing prevents service brake and parking brake force to be superimposed damage system
Dynamic system element.
The utility model is integrated by relay valve 3, double-way check valve B2 (quick release valve), double-way check valve A1 and ABS solenoid valve 4
It is compact-sized for a combination valve, production cost can be reduced with effective solution arrangement and assembly problem.
It, can be with when parking braking and service brake act on simultaneously since double-way check valve A1 is combined with double-way check valve B2
The superposition for avoiding brake force causes the damage of braking member.
Since relay valve 3 is directly combined with ABS solenoid valve 4, the relay valve 3 and ABS electricity of braking response time are seriously affected
Pipeline between magnet valve 4 no longer exists with connector, and the braking response time is greatly reduced.
Since relay valve 3 is directly combined with ABS solenoid valve 4, brake chamber compressed air directly passes through the exhaust of combination valve
Mouth 5 is discharged, and can be braked with Rapid reversal, so the decompression process of ABS and brake return time are significantly less, be improved
ABS performance simultaneously reduces braking temperature rise.
Combination valve provided by the utility model is integrated with the function of relay valve and quick release valve, double-way check valve, ABS solenoid valve
Can, it is compact-sized, the reliable braking of travelling gantry frame and braking anti-lock, realization parking system after vehicle air braking system may be implemented
It moves and brake force is prevented to be superimposed；After integrated, corresponding connecting line and connector are eliminated, shortens and simplifies brake piping and connect
It connects, improves the sensitivity of driving and parking braking, reduce production cost and installation difficulty.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
