Fig. 1 is the gas circuit control principle figure of parking control device of the pneumatic brake vehicle of prior art.
Fig. 2 is the gas circuit control principle figure of the parking control device of the utility model embodiment.
Fig. 3 is the circuit control principle figure of the parking control device of the utility model embodiment.
The specific embodiment
The exemplary embodiments that embodies the utility model characteristic and advantage will be described in detail in following explanation.Be understood that the utility model can have various variations on various embodiment, the scope of its neither disengaging the utility model, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the utility model.
The parking control device of the utility model is applicable to the pneumatic brake passenger vehicle, and double loop pneumatic brake passenger vehicle especially comprises the bus that security requirement is high and the passenger train of mountain area road conditions.
The pneumatic brake vehicle of the utility model embodiment has the parking control device of the utility model.
As shown in Figures 2 and 3; The parking control device of the utility model embodiment; Comprise bonded assembly rapid release valve 6 between inflation pump 1, air dryer 2, four-loop protection valve 3, hand braking air receiver 4, hand brake valve 5, two energy storage spring brake chamber 7 and two energy storage spring brake chamber 7; Different with prior art parking control device shown in Figure 1 is; On gas circuit, also be provided with braking during standstill electromagnetic valve 8,8 of braking during standstill electromagnetic valves are in the control circuit that is made up of hand brake valve position switch 11, relay 9, normal power supply 13 and driving engine ON shelves power supply 14, and normal power supply 13 can be 24V with driving engine ON shelves power supply 14.
Braking during standstill electromagnetic valve 8 is an open type, and gas circuit is connected between hand brake valve 5 and the rapid release valve 6, then is to be connected between hand brake valve position switch 11 and the relay 9 on the circuit.Under braking during standstill electromagnetic valve 8 cold situation; Braking during standstill electromagnetic valve 8 can't be blocked the gas circuit between hand brake valve 5 and the rapid release valve 6, thereby generally, when chaufeur at the ON shelves power supply 14 that kills engine; During pull-up hand brake valve 5, can realize braking during standstill smoothly; And when 8 energisings of braking during standstill electromagnetic valve, then can break off the gas circuit between hand brake valve 5 and the rapid release valve 6, so that the gas in the energy storage spring brake chamber 7 is realized braking during standstill through rapid release valve 6 exhausts.The circuit of braking during standstill electromagnetic valve 8 is connected the state that then depends on hand brake valve position switch 11 and relay 9 and is changed.
The parking control device of the utility model embodiment; Its hand brake valve position switch 11 is arranged on the handle of hand brake valve 5, on circuit connects; One end ground connection; Other end circuit is connected in braking during standstill electromagnetic valve 8, and hand brake valve position switch 11 breaks off during pull-up hand brake valve 5, and hand brake valve position switch 11 closures are not connected with the circuit of braking during standstill electromagnetic valve 8 when shaking hands brake activation valve 5.Therefore, when chaufeur was forgotten handle brake activation valve 5, braking during standstill electromagnetic valve 8 just might be a "on" position.
The parking control device of the utility model embodiment; The principle of work of its braking during standstill control is: the braking during standstill electromagnetic valve 8 of increase does not influence conventional parking braking function; And when chaufeur forgets that the abnormal condition of handle brake activation valve 5 take place; Gas circuit is broken off in circuit control braking during standstill electromagnetic valve 8 energisings through braking during standstill electromagnetic valve 8 places; Make the gas in the energy storage spring brake chamber 7 lead to atmosphere through rapid release valve 6 exhausr ports (not marking among the figure), this moment, the power through energy stroage spring realized braking during standstill.
The parking control device of the utility model embodiment; Its circuit control principle is as shown in Figure 3; When driving engine was in shutdown (stopping working) state, when (promptly kill engine ON shelves power supply 14 or extract key), the closure state of hand brake valve position switch 11 showed that chaufeur does not have pull-up hand brake valve 5; This often power supply 13 be to braking during standstill electromagnetic valve 8 through relay 9 normally closed contacts; And, make and 8 energisings of braking during standstill electromagnetic valve realize automatic parking brake through hand brake valve position switch 11 ground connection formation loop.Open driving engine ON shelves power supply 14 or fire an engine, parking brake automatic release once more up to chaufeur.
Among Fig. 3; After opening driving engine ON shelves power supply 14, whether the air pressure that detects energy storage spring brake chamber 7 reaches the starting air pressure of regulation, if out of reach starting air pressure then connect braking during standstill switch 10; At this moment the hand braking indicator lamp 12 on the gauge panel lights, and reminds driver's air pressure not enough.
Can know by above argumentation, the parking control device of the utility model, control circuit is simple, reliable, and when conventional braking during standstill, Circuits System does not have power consumption, only when automatic parking brake, the work of just switching on of the coil of braking during standstill electromagnetic valve 8.And only closed at driving engine ON shelves power supply 14, hand brake valve position switch 11 shows chaufeur not during pull-up hand brake valve 5, the work of just switching on of the coil of braking during standstill electromagnetic valve 8.Therefore the parking control device of the utility model has energy-saving advantages.
In the parking control device of the utility model embodiment, above-mentioned rapid release valve 6 also can replace with relay valve, and four-loop protection valve 3 also can be the multiloop protective valve
The pneumatic brake passenger vehicle of the parking control device of the utility model and the utility model; Realized the automatic safe protective effect; Promoted the vehicle safety grade; Meet GB12676 " brake system of car structure, performance and test method " rules, the passenger train that is suitable for bus and mountain area road conditions especially uses.
Those skilled in the art should recognize change and the retouching of under the situation of scope that does not break away from the appended the utility model that claim disclosed of the utility model and spirit, being done, and all belong within the protection domain of claim of the utility model.
