Specific embodiment:
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, a kind of electronic parking control system of the present invention, including parking braking gas receiver 1, electronics parking brake switch
2, two-bit triplet solenoid valve 3, differential type relay valve 4, rear brake chamber 5, air brake piping 6 and control route 7.Parking braking storage
Inflator 1 is connected by two correspondences of air brake piping 6 with two-bit triplet solenoid valve 3 and differential type relay valve 4, two-bit triplet electromagnetism
Valve 3 is connected with differential type relay valve 4 by an air brake piping 6, the parking of brake chamber 5 after differential type relay valve 4 connects
Chamber, electronics parking brake switch 2 with control route 7 with two-bit triplet solenoid valve 3 by being connected.
Electronic brake system of the present invention is by brake piping 6 parking braking gas receiver 1 and two-bit triplet solenoid valve 3
And differential type relay valve 4 and rear brake chamber 5 connect, by control route 7 two-bit triplet solenoid valve 3 and electronic hand
Switch 2 of stopping is connected with vehicle circuitry.
Electronics parking brake switch 2 is rocker switch, and band P signal lamp has former and later two positions, is forward the intervention of electronics parking brake
Work, vehicle are in parked state, and P lamp is bright at this time, release state backward for parking brake, vehicle, which is in, can exercise state, and P lamp is put out
It goes out.
Two-bit triplet solenoid valve 3 is worked, before remaining powered off after power-off after powered up using the solenoid valve with memory function
Operating position, change until powering on rear operating position again.Two-bit triplet solenoid valve 3 has 3 ports, wherein No. 1
Mouth is air inlet, and No. 2 mouths are gas outlet, and No. 3 mouths are exhaust outlet.No. 1 mouth connect 1, No. 2 mouths of parking braking gas receiver connect differential type after
Dynamic 4, No. 3 mouths of valve are exhaust outlet.After two-bit triplet solenoid valve 3 is powered, No. 1 mouth and No. 2 mouths, at this time parking are connected in generation movement
It brakes gas receiver 1 and differential type relay valve 4 is connected, parking braking releases, and vehicle, which is in, can exercise state, two-bit triplet electromagnetism
Valve 3 powers off, since with memory function, No. 1 mouth and No. 2 mouths are still in on-state.After being once again powered up, two-bit triplet solenoid valve
3 generations movement, 2 good mouths are connected with No. 3 exhaust outlets, and No. 1 mouth is closed, at this time differential type relay valve 4 and two-bit triplet solenoid valve 3 it
Between gas be in parking braking state by the discharge of No. 3 mouths, vehicle, power off again, solenoid valve keeps the state.
When work, 2 rocker switch of electronics parking brake switch is pressed backward, and two-bit triplet solenoid valve 3 is powered, and connects No. 1 air inlet
Mouth and No. 2 gas outlets, signal gas source reaches No. 4 mouths of differential type relay valve at this time, opens No. 1 mouth of differential type relay valve 4, rear system
5 parking chamber of room of taking offence inflation, parking braking release, and vehicle, which is in, can exercise state, and P signal lamp is put out on electronics parking brake switch 2
It goes out, then two-bit triplet solenoid valve 3 powers off, and due to the memory function of two-bit triplet solenoid valve 3, valve body can keep No. 1 mouth and No. 2
Mouth is identical, and vehicle is constantly in parking braking and releases state.When needing parking braking, electronics parking brake switch 2 is pressed forward and is stuck up
Switching plate, two-bit triplet solenoid valve 3 are powered, and spool built in valve body is mobile, so that No. 1 mouth and No. 2 mouths disconnect, No. 3 mouths and No. 2 mouths
It connects, gas is arranged by No. 3 mouths of two-bit triplet solenoid valve 3 between two-bit triplet solenoid valve 3 and differential type relay valve 4 at this time
It removes, rear 5 parking chamber gas of brake chamber is excluded by differential type relay valve 4, and vehicle is in parking braking state, and electronics parking brake
P signal lamp is lighted on switch 2, and then two-bit triplet solenoid valve 3 powers off, also due to memory function, 3 meeting of two-bit triplet solenoid valve
No. 2 mouths and No. 3 mouths are kept to connect, so that vehicle is constantly in parking braking state.
Air brake piping 6 uses PA material pipeline or metal tubes.
The components such as differential type relay valve and gas receiver brake chamber in the present invention are identical as conventional brake gas circuit original part,
It does not repeat them here.
The present invention switchs to control the energization and power-off of two-bit triplet solenoid valve by electronics parking brake, and then controls solenoid valve
The on off operating mode of stomata, when electromagnetic valve air inlet and gas outlet are connected, vehicle be in parking braking releasing state, and vehicle can be with
Normally travel, electronics parking brake switchs upper P lamp and extinguishes at this time, and when electromagnetism valve air gate and exhaust outlet connection, vehicle is in parking
On-position, vehicle can not travel, and electronics parking brake switchs upper P lamp and lights at this time.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
