Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
A kind of passenger vehicle parking brake is as shown in Figure 1 met an urgent need deactivation system, comprises hand braking air receiver 1, air receiver for subsequent use 2, emergency switch 3, inflation pump 6, parking brake 7, rapid release valve 8, first check valve 5, second check valve 4 and hand braking air chamber 9.
The air extractor duct of described inflation pump 6 is connected through first admission port of the first check valve 5 with hand braking air receiver 1.First air extractor duct of described hand braking air receiver 1 is connected with the admission port of parking brake 7, the admission port 81 of rapid release valve 8 respectively.The air extractor duct of described parking brake 7 is connected with the control mouth 83 of rapid release valve 8.The air extractor duct 83 of described rapid release valve 8 is connected with the admission port of hand braking air chamber 9.Second air extractor duct of described hand braking air receiver 1 is connected through the admission port of the second check valve 4 with air receiver 2 for subsequent use.The air extractor duct of described air receiver for subsequent use 2 is connected through second admission port of emergency switch 3 with hand braking air receiver 1.
The air extractor duct of described inflation pump 6 is also connected with the admission port of passenger vehicle other system.Described passenger vehicle other system comprises foot brake system, Suspension air bag system, passenger door, air pressure horn etc. and uses gas system.
Described emergency switch 3 adopts knob pipeline switch, can control the break-make of air pipe by rotating knob.
Described rapid release valve 8 comprises an admission port, two air extractor ducts, an exhausr port and a control mouth.As shown in Figure 1, the admission port 81 of rapid release valve takes over the first air extractor duct of braking air receiver; An air extractor duct 82 of rapid release valve takes over the admission port of compressed air brake cylinder 9, and another air extractor duct connects stop lamp switch; Rapid release valve control mouth 83 catcher stop 7 air extractor duct.In time controlling mouth 83 and ventilate, valve open inside rapid release valve, the admission port 81 of rapid release valve is connected with air extractor duct 82, makes gas can enter hand braking air chamber 9 brake off.When the control mouth 83 of rapid release valve is airproof time, the admission port 81 of rapid release valve is not connected with air extractor duct 82, and gas can not enter hand braking air chamber 9, and the gas of hand braking air chamber 9 can discharge rapidly passenger vehicle braking by the exhausr port of rapid release valve.The effect of rapid release valve 8 shortens gas flow path and then shortens the braking corresponding time.
Principle of work of the present invention is:
To meet an urgent need according to the passenger vehicle parking brake shown in Fig. 1 the systematic schematic diagram of deactivation system, connect the air pipe of this emergent deactivation system.When passenger vehicle normally works, emergency switch 3 cuts out, and inflation pump 6 can supply pressurized air until system pressure reaches specified value for hand braking air receiver 1 and air receiver for subsequent use 2.The compressed-air actuated flow direction as illustrated by the arrows in fig. 1.
To leave behind under normal circumstances parking brake 7, a pressurized air part in hand braking air receiver 1 enters by parking brake 7 admission line that rapid release valve 8 controls rapid release valve 8 and opens, and the pressurized air now in hand braking air receiver 1 can enter hand braking air chamber 9 by rapid release valve 8 and remove hand braking.When pulling on parking brake, because do not have the admission line of gas pressure rapid release valve 8 to close, the air in hand braking air receiver 1 can not enter hand braking air chamber 9, and the pressurized air simultaneously in hand braking air chamber 9 will enter air by rapid release valve 8, now parking brake 7 comes into force, and passenger vehicle will be braked.
During passenger vehicle et out of order, when such as inflation pump 6 cannot work or other system 10 gas leakage causes the gas of inflation pump 6 effectively can not be delivered to hand braking air receiver 1, hand brake system 7 cannot provide normal barometric pressure, and parking brake 7 can not be removed.Now all will bring inconvenience to the maintenance of vehicle and transhipment.By technical solutions according to the invention, can effectively solve the problem.Concrete reason is as follows:
First, owing to being provided with the first check valve 5 between inflation pump 6 and hand braking air receiver 1, gas in hand braking air receiver 1 can not leak because other system 10 leaks gas, and the pressurized air when vehicle abnormality in hand braking air receiver 1 still can keep hand brake system normal operation a period of time.When passenger vehicle et out of order, inflation pump 6 effectively can not provide pressurized air, and gas can not flow from the first check valve 5 toward hand braking air receiver 1, and at this moment hand braking air receiver 1 is equivalent to source of the gas.Under pressure, gas in hand braking air receiver 1 can from outlet toward other local flowings, now, the effect of the first check valve 5 is exactly cut off the contact between hand brake system 1 and other system 10, makes a gas standard enter to be forbidden preferentially to ensure brake system work.Because secure item needs preferential guarantee during braking, if do not have the first check valve 5, the gas in hand braking air receiver 1 just may run off from other system 10 or fault.Along with the use of vehicle, pressurized air in parking brake air receiver 1 can more with fewer, air pressure is more and more lower, and because have the second check valve 4 and rotor switch 3, gas in air receiver 2 for subsequent use is also only import but no export, pressurized air wherein can not flow into hand braking air receiver 1 because of the pressure step-down of hand braking air receiver 1, the effect of the second check valve 4 and rotor switch 3 is exactly prevent gas to run off completely, can after in hand braking air receiver 1, gas be finished, vehicle has occurred that fault checks in time to allow chaufeur recognize, at this moment the effect that rotor switch 3 just can play emergency use is turned on again.If do not have the cooperation of the second check valve 4 and rotor switch 3, the gas in air receiver 2 for subsequent use also can consume along with the use of vehicle, does not have the urgent effect used.
Secondly, because emergency switch 3 is closed condition at ordinary times, by arranging the second check valve 4 in the middle of hand braking air receiver 1 and air receiver for subsequent use 2, can ensure that air receiver 2 for subsequent use only can be inflated and can not be vented outward, therefore in air receiver 2 for subsequent use, storing the pressurized air of authorized pressure value always.When parking brake 7 cannot proper solution except time, illustrate that the pressurized air in hand braking air receiver 1 is also finished, and passenger vehicle breaks down and normally cannot provide pressurized air, remind chaufeur maintenance and inspection vehicle.Now, open emergency switch 3, the outlet by hand braking air receiver 1 is entered hand brake system 7 by the pressurized air in air receiver 2 for subsequent use, for hand brake system 7 provides pressure to ensure that hand brake system still can normal operation to remove parking brake.Same owing to being provided with the first check valve 5, the pressurized air that ensure that in air receiver 2 for subsequent use can not flow into other system and cause Leakage Gas or air pressure too low, preferentially ensure that hand brake system normally uses.
In sum, the present invention when passenger vehicle et out of order air pressure is not enough for hand brake system provides enough air pressure, can ensure that hand brake system normally works, facilitates dragging and the maintenance of fault car.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
