The beneficial effects of the utility model are: simple in structure, easy for installation, cheap, improve pilot control traveling comfort and comfort feature, especially adopt electromagnetic valve and solenoid control switch, common control relay valve control end, the brake off time and the braking time of emergency brake system have been shortened, can make the quick braking during standstill of automobile and remove braking during standstill fast, improved the performance of parking brake of automobile, and had chaufeur orderly shutdown outage back vehicle automatic parking brake and do not slip the advantage of car.
Description of drawings
Accompanying drawing has provided the structural representation of the utility model automobile electric control parking brake equipment.
Wherein, the auxiliary air receiver of 1-, 2-relay valve, 3-hand control valve (HCV), 4-tracheae, 5-electromagnetic valve, 6-connect electric wire, 7-button switch, 8-brake application by spring air chamber
The specific embodiment
Be described further below in conjunction with the enforcement of accompanying drawing: in the utility model the utility model automobile electric control parking brake equipment, auxiliary air receiver 1 air extractor duct is connected with relay valve 2 admission port P, hand control valve (HCV) 3 admission ports by tracheae 4 and T-pipe joint, so that relay valve 2, hand control valve (HCV) 3 are obtained pressurized air from auxiliary air receiver 1, auxiliary air receiver 1 pressurized air is provided by automobile air compressor.Relay valve 2 air extractor duct A are connected with automobile axle left and right sides brake application by spring air chamber 8 spring cavity admission ports by tracheae 4 and T-pipe joint.Electromagnetic valve 5 is connected its air extractor duct A by crossover sub with relay valve 2 control mouthful K, electromagnetic valve 5 admission port P are connected with hand control valve (HCV) 3 air extractor ducts by tracheae 4.Electromagnetic valve 5 wire frame positive wires link to each other with button switch 7 one ends on the facia board by connecting electric wire 6, and button switch 7 other ends are connected with automobile power source, and electromagnetic valve 5 wire frame negative wires are connected with the vehicle frame bonding.Connecting electric wire 6 is solid conductor, can guide on the facia board button switch 7 along the automobile electric appliance system circuit, and button switch 7 can be selected automotive controls for use, and button switch 7 is installed on the spare space of being convenient to driver's operation on the facia board.
Automobile is when normal condition, and hand control valve (HCV) 3 is in the driving connected state all the time, delivers to electromagnetic valve 5 admission port P will assist air receiver 1 compressed air by hand control valve (HCV) 3 admission ports and air extractor duct.
When automobile stops to need braking during standstill, chaufeur is pressed the button switch 7 of the control electric control parking brake equipment on the facia board to open position, electromagnetic valve 5 admission port P and air extractor duct A are cut off in electromagnetic valve 5 outages, simultaneously relay valve 2 a controls mouthful K Pneumatic pipe cleaner is crossed electromagnetic valve 5 exhausr port O exhaust to atmospheres, relay valve 2 cuts off its admission port P and air extractor duct A immediately, simultaneously brake application by spring air chamber 8 spring cavity compressed airs are passed through relay valve 2 exhausr port O exhaust to atmospheres, under the 8 energy stroage spring effects of brake application by spring air chamber, produce thrust and finish braking during standstill in drg.
When automobile normal running need be removed braking during standstill, chaufeur is pressed the button switch 7 of the control electric control parking brake equipment on the facia board to control position, electromagnetic valve 5 admission port P and air extractor duct A are connected in electromagnetic valve 5 energisings, pressurized air is by auxiliary air receiver 1, hand control valve (HCV) 3 admission ports and air extractor duct, tracheae 4, electromagnetic valve 5 admission port P and air extractor duct A enter relay valve 2 control mouthful K, relay valve 2 admission port P and air extractor duct A connect, pressurized air is by auxiliary air receiver 1, relay valve 2 admission port P and air extractor duct A, tracheae 4 enters brake application by spring air chamber 8 spring cavitys, overcomes the energy stroage spring effect and finishes the releasing braking during standstill.
When stopping outage, chaufeur behind the automobile normal running forgets when the button switch 7 of pressing control electric control parking brake equipment carries out braking during standstill that because the disconnection of automobile general supply makes electromagnetic valve 5 outages simultaneously, automobile is finished braking during standstill.
