This brake activation valve valve body one side is provided with and cooresponding two the opening T mouths of valve piece, P mouth, and the valve piece was not closed T mouth, P mouth when brake spool was stressed, and the valve body opposite side is provided with the A mouth that staggers with T mouth, P mouth.
This P mouth connects the high pressure oil of hydraulic power unit; The T mouth is a return opening, connects fuel accumulator; The A mouth connects brake piping and brake wheel cylinder.
This magnet coil is the ratio magnet coil.
A kind of control method of dynamo-electric double-purpose brake activation valve, glancing impact, the sensor sensing pedal is stressed and change in location that cause produces corresponding signal and sends to electronic controller, electronic controller provides corresponding electric current to magnet coil, thereby electromagnetic force that control coil produces and then control armature, brake spool move braking; Perhaps glancing impact, the stressed mechanical action end that passes to of brake pedal, thus and then pass to mechanical action spring control brake spool and move braking.
This brake spool moves its uuper valve block of drive and moves, the P mouth is opened, high pressure oil leads to brake wheel cylinder, brake-pipe pressure increases and brakes, brake-pipe pressure feeds back to the right-hand member of spool by oil duct, form feedback force, the former suffered force balance of feedback force and brake spool drives brake spool and oppositely moves to balance position, and brake-pipe pressure keeps; Braking is finished, and the power on the pedal removes, and brake spool is subjected to feedback force control to continue oppositely to move, and T mouth and A mouth are connected, brake-pipe pressure decline end of braking.
Owing to adopted such scheme, the present invention to have following characteristics: the present invention adopts electric-hydraulic combined braking brake activation valve, has realized the line control of brake piping hydraulic coupling, even and electrical accident appears, it still can adopt mechanical braking to brake.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
The dynamo-electric double-purpose brake activation valve of the present invention, comprise pedal sense spring 1, brake pedal 2, pedal position sensor 3, mechanical action end 4, mechanical action spring 5, ratio magnet coil 6, armature 7, brake spool 8, electronic controller 9, it mainly is to have set up pedal position sensor 3, electronic controller 9, ratio magnet coil 6, armature 7 on existing brake activation valve, the line pressure of brake system is controlled by dynamo-electric double-purpose brake activation valve, brake spool 8 is a direct dynamic structure, and the action of spool can independently be realized by ratio magnet coil 6 and 4 liang of nested structures of mechanical action end.Wherein sensor 3 is installed on the pedal 2, when the chaufeur glancing impact, controller 9 obtains braking requirement information according to the sensor 3 that is arranged on the brake pedal 2, in case promptly pedal 2 is stressed, sensor 3 is about to corresponding signal and is transferred to coupled electronic controller 9, electronic controller 9 provides corresponding electric current to coil 6, make armature 7 be subjected to electromagnetic force and move to right, thereby spool 8 moves to right and realizes braking, just realizes the line traffic control of brake-pipe pressure by control ratio magnet coil 6, armature 7 power outputs; In addition, when the line control system fault, the treadle effort of chaufeur can be realized the mechanical backup braking potential under the electrical accident directly by the mechanical action end 4 pilot piping pressure of brake activation valve.
Driver pedal power can act on the output hydraulic pressure of direct control A mouth on the relief pressure valve cartridge 8 by mechanical action end 4 and spring 5 thereof, and meanwhile, ratio magnet coil 6 and armature 7 also can act on electromagnetic force on the relief pressure valve cartridge 8.The P mouth of reducing valve connects the high pressure oil of hydraulic power unit; The T mouth is a return opening, connects fuel accumulator; The A mouth connects brake piping and brake wheel cylinder.Two round table surface valve pieces of spool 8 are closed P mouth and T mouth respectively when midway location.When electronic controller 9 collected the pedal position increase by pedal position sensor 3, control ratio magnet coil 6 electric currents increased, and the recruitment of electric current is corresponding with pedal 2 displaced phases.Export electromagnetic force spool 8 is moved right this moment, opens the P mouth, and high pressure oil flows to brake wheel cylinder, and brake-pipe pressure increases.Brake-pipe pressure feeds back to the right-hand member of spool 8 by oil duct, forms feedback force.When feedback force and electromagnetic force equilibrium, spool 8 is got back to meta once more, and brake-pipe pressure keeps.When chaufeur loosens pedal 2, pedal 2 is return under the effect of pedal sense spring 1, the output of pedal position sensor 3 reduces, the electric current of electronic controller 9 control magnet coils 6 reduces accordingly, thereby reduce electromagnetic force, feedback force pushes away spool 8 left sides, and T mouth and A mouth are connected, and brake-pipe pressure descends.
In the normal brake-by-wire process, electronic controller 9 is according to the electric current of the signal magnitude control ratio magnet coil 6 of pedal position sensor 3, thus the electromagnetic force of control action on armature 7 and relief pressure valve cartridge 8.When pedal displacement increased, control ratio magnet coil 6 electric currents increased, and the output electromagnetic force moves right spool 8, opens the P mouth, and high pressure oil leads to brake wheel cylinder, and brake-pipe pressure increases.Brake-pipe pressure feeds back to the right-hand member of spool 8 by oil duct, forms feedback force.When feedback force and electromagnetic force equilibrium, spool 8 is got back to meta once more, and brake-pipe pressure keeps.When chaufeur loosens pedal 2, pedal position reduces under the effect of pedal sense spring 1, and electronic controller 9 control ratio magnet coils 6 electric currents reduce, thereby electromagnetic force reduces, and feedback force pushes away spool 8 left sides, and T mouth and A mouth are connected, and brake-pipe pressure descends.
When electrical malfunction, the electromagnetic force forfeiture of coil 6, chaufeur is by stepping on brake pedal 2 deeply, can directly treadle effort be acted on the power operation end 4 of control cock, treadle effort acts on the end of armature 7 by spring 5, replace the effect of electromagnetic force, make reducing valve output and the corresponding hydraulic braking force of driver's operation power.
In the braking procedure, pedal sense is mainly produced by pedal sense spring 1.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
