Description
Technical field
The invention belongs to the brake device for car technical field, particularly have the vapour-pressure type integrated electronic braking valve for vehicle of emergency operation during a kind of braking during standstill.
Background technology
At present, the manual pneumatic holding brake device of medium-heavy automobile, " break brake " principles that adopt by the hand braking exhaust of braking during standstill air chamber, the generation braking during standstill of making more.For realizing braking during standstill and removing braking during standstill, usually adopt solenoid directional control valve to finish the intake and exhaust operation.Two-bit triplet electromagnetic valve commonly used is generally single automatically controlled (being unicoil), is divided into two kinds of closed type and open types.The operating principle of closed type two-bit triplet solenoid directional control valve is: to the control coil energising, gas circuit is connected; Coil is outage in a single day, and gas circuit will disconnect immediately.The operating principle of open type two-bit triplet solenoid directional control valve is: to the control coil energising, gas circuit disconnects; Coil is outage in a single day, and gas circuit will demand working.No matter closed type or open type solenoid directional control valve, the on off mode that keep gas circuit all need continue energising, and control coil is continued energising, will greatly shorten the service life of coil.
The two electric control electromagnetic change-over valves of present two-bit triplet on the market can cut off the power supply after giving direct action coil electricity 1s again, still can keep the on-state of gas circuit, and will last till that till the reverse action coil electricity, this is equivalent to " self-locking ".Based on this characteristic, can shorten the current"on"time of coil, reduce the cal val of coil, adopt in addition " self-locking " principle the service life of extension coil, can also prevent in the electromagnetic valve work process because cable bad causes parking function unusual.
Chinese patent application " air-pressure type electronic emergency brake system and braking method " (application number: 201010238129.8, open day: on November 10th, 2010) disclose a kind of air-pressure type electronic holding brake device and braking method, the air-pressure type electronic Parking valve that this air-pressure type electronic holding brake device comprises comprises a two-bit triplet solenoid directional control valve, receive the manual mode switch signal by Parking Brake, judge whether to implement Parking or remove braking during standstill, thereby give the coil electricity of two-bit triplet solenoid directional control valve, realization intake and exhaust operation is finished and is removed braking during standstill or braking during standstill.Described air-pressure type electronic Parking valve comprises solenoid directional control valve, check valve, priority valve, the C mouth of air-pressure type electronic Parking valve links to each other with solenoid directional control valve, solenoid directional control valve links to each other with the control mouth of priority valve, the A mouth of air-pressure type electronic Parking valve links to each other with the admission port of priority valve, the air extractor duct of priority valve links to each other with the B mouth of air-pressure type electronic Parking valve again, check valve links to each other with the solenoid directional control valve two ends, and the airintake direction of check valve is opposite with the airintake direction of solenoid directional control valve.Though the two-bit triplet solenoid directional control valve that this cover air-pressure type electronic holding brake device comprises can be finished braking during standstill or remove the basic operation of Parking, but still there are the following problems:
1, this solenoid directional control valve needs just can keep the intake and exhaust operation in lasting energising situation, removes braking during standstill or braking during standstill thereby finish, and coil continues energising and easily burns and cause the electromagnetic valve inefficacy.
2, owing to cancelled hand braking handle in the operator's compartment, if emergency brake system lost efficacy, such as owing to faults such as storage battery electricity shortage, electromagnetic valve hot-wire coil burn, can't carry out braking during standstill in the Vehicle Driving Cycle process, this will reduce the safety in utilization of vehicle.
Summary of the invention
The object of the present invention is to provide a kind of vapour-pressure type integrated electronic braking valve for vehicle with emergency operation, when the air-pressure type electronic emergency brake system lost efficacy, can in the operator's compartment emergency operation, realize safe and reliable braking during standstill or releasing.
The technical solution that realizes the object of the invention is: a kind of vapour-pressure type integrated electronic braking valve for vehicle with emergency operation, comprise main valve, the first pilot valve, the second pilot valve, described main valve has the exhausr port that communicates with atmosphere respectively, the inflation inlet that communicates with air receiver, the relief port that communicates with the braking during standstill air chamber, be provided with in the described main valve by its evolution and can make respectively exhausr port and relief port conducting or make inflation inlet and the main valve plug of relief port conducting, described the first pilot valve is provided with the gas circuit that communicates with main valve, also be provided with the braking admission port that communicates with air receiver side gas circuit and the braking exhausr port that communicates with atmosphere, also be provided with in described the first pilot valve and can make its evolution by braking during standstill end-coil power on/off, make respectively braking admission port and main valve conducting or make the first spool of braking exhausr port and main valve conducting, described the second pilot valve is provided with the gas circuit that communicates with main valve, also be provided with the braking releasing exhausr port that the braking that communicates with air receiver side gas circuit is removed admission port and communicated with atmosphere, also be provided with in the second pilot valve and can make its evolution by removing Parking end-coil power on/off, make respectively braking remove admission port and main valve conducting or make and brake the second spool of removing exhausr port and main valve conducting, this valve comprises that also an end links to each other with the first spool in the first pilot valve, the emergency brake mechanism that the other end links to each other with emergency brake draw ring in the operator's compartment by backguy and an end link to each other with the second spool in the second pilot valve, and the other end is removed the emergency brake cancel system that draw ring links to each other by backguy with the emergency brake in the operator's compartment.
The present invention compared with prior art, its remarkable advantage:
1, safe and reliable: vapour-pressure type integrated electronic braking valve for vehicle of the present invention has emergency mechanism, can electricity shortage appear at storage battery, or there is electrical accident in electronic brake system itself, when causing to carry out braking during standstill or removing braking during standstill, realize braking during standstill or remove braking during standstill, safe and reliable braking during standstill or releasing braking during standstill by chaufeur drawing braking during standstill (or removing braking during standstill) stay thimble in operator's compartment;
2, long service life: the present invention adopts the two-bit triplet double control electromagnetic change-over valve with " self-locking " function; can after giving direct action coil electricity 1s, cut off the power supply; still can keep the gas circuit on-state and last till till the reverse action coil electricity; can protect the current"on"time that significantly shortens coil; make coil not fragile, prolong the service life of electromagnetic valve.
