Technical field：
The present invention relates to a kind of emergent deactivation system of car parking brake and its release method.
Background technology：
At present, car typically uses air-pressure brake, is provided by electric inflation pump or the operating of driven by engine inflating pump
Compressed air, and compressed-air-storing is used in gas receiver for brakes.When parking brake gas receiver air pressure is less than certain value
When, gas pressure can not overcome the spring force in brake chamber, and car will carry out parking braking, now only to parking brake gas receiver
Again inflation could release braking.So, car break down cause parking brake locking when, it is necessary to from the gas-charging connection of front of the host
Releasing locking is inflated again to parking brake gas receiver, this is very inconvenient for the operating and maintenance of car.
Car parking brake of the prior art is met an urgent need release method, and such as notification number discloses for CN105128835A patent document
A kind of car parking brake meet an urgent need deactivation system and its release method, including parking brake gas receiver, standby gas receiver, emergency button, beat
Air pump, parking brake, quick release valve, the first check valve, the second check valve and hand braking air chamber.Parking brake gas receiver and standby gas receiver is simultaneously
Connection, when car failure can not be effectively hand braking offer braking pressure, provides compressed air for hand brake system temporarily.Although
The system can meet an urgent need releasing parking brake, but need to add a standby gas receiver, and this standby gas receiver is only in parking brake gas
Just played a role when pressing through low, to trouble is brought in very compact chassis space arrangement originally, especially for pure electric coach
For.
The content of the invention：
The present invention is to provide a kind of car parking brake emergent deactivation system in order to solve the problem of above-mentioned prior art is present
And its release method.

Even, emergency button is connected with parking braking air chamber.
Further, the emergency button uses rotary pipeline switch, and the break-make of air pipe is controlled by turn knob.
The present invention is also adopted the following technical scheme that：A kind of car parking brake is met an urgent need release method, is comprised the following steps：
(1) during car normal work, close emergency button, the condensed device of inflating pump, drier, standby gas receiver, four times
Road protects valve to provide compressed air to parking brake gas receiver, until system pressure reaches setting；System pressure is whole car system
The pressure of dynamic system, now the pressure of each gas receiver is identical；
(2) when car normal work and emergency button closing, the flow direction of gas is in the emergent deactivation system of car parking brake：
First, the compressed gas of inflating pump passes through condenser, the air inlet of standby gas receiver is then entered from condenser gas outlet, from standby
Enter the air inlet of drier with the gas outlet of gas receiver, the air inlet of four-loop protection valve entered from the gas outlet of drier,
Enter the air inlet of parking brake gas receiver from the gas outlet of four-loop protection valve, enter hand control valve from the gas outlet of parking brake gas receiver
Air inlet, the air inlet of differential type relay valve is entered from manual valve air gate, and then the gas outlet of parking brake gas receiver enters differential
The air inlet of formula relay valve, finally enters parking braking air chamber from the gas outlet of differential type relay valve；
(3) when supply or gas path failure occur for car, stayed if the gas pressure value in parking brake gas receiver can not push up to open
The energy-stored spring of car brake chamber, now opens emergency button, releases gas in parking braking, the emergent deactivation system of car parking brake
Flow direction be：Enter the air inlet of emergency button from the gas outlet of standby gas receiver, from the gas outlet of emergency button to parking system
Take offence the air inlet of room, the energy-stored spring of parking braking air chamber, parking braking solution are opened in the gas pressure value top in standby gas receiver
Except the present invention has the advantages that：Increase a standby gas receiver before drier after the condenser, occur in car
During failure, by opening emergency button, parking braking is released, it is not necessary to exclusively carry out inflation, convenient maintenance；In addition standby gas storage
Cylinder can also play a part of current stabilization, cooling and dehumidify, and vehicle gas-storing capacity is improved again.
Brief description of the drawings：
Fig. 1 is the systematic schematic diagram of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
The deactivation system as shown in figure 1, a kind of car parking brake of the invention is met an urgent need, including inflating pump 1, condenser 2, standby gas storage
Cylinder 3, drier 4, four-loop protection valve 5, parking brake gas receiver 6, hand control valve 7, the parking braking air chamber 9 of differential type relay valve 8 and should
Anxious switch 10, the gas outlet of inflating pump 1 is connected with the air inlet of condenser 2, the gas outlet of condenser 2 and the air inlet of drier 4
Mouth is connected, and the gas outlet of drier 4 is connected with the air inlet of standby gas receiver 3, and gas outlet and four loops of standby gas receiver 3 are protected
Protect valve 5 to be connected, the gas outlet of four-loop protection valve 5 is connected with parking brake gas receiver 6, two on parking brake gas receiver 6 gas outlet point
It Dui Ying not be connected with the air inlet of hand control valve 7 and the air inlet of differential type relay valve 8, the gas outlet of hand control valve 7 and differential type
Air inlet on relay valve 8 is connected, and the gas outlet of differential type relay valve is connected with parking braking air chamber 9；Standby gas receiver 3 goes out
