Description
Technical field
The utility model relates to vehicle safety equipment, refers in particular to a kind of braking system gas circuit of improved air break automobile.
Background technology
The braking system gas circuit of air break automobile, routine is such design-calculated: air compressor, wet air receiver, main air reservoir pipeline successively are communicated with, main air reservoir one road pipeline is connected to the brake control valve that is communicated with each compressed air brake cylinder, and another road plumbing connection one barometric regulator is connected the unloader valve of air compressor.The pressurized air that air compressor pumps enters wet air receiver, carry out oil separation after, clean pressurized air enters main air reservoir.Automobile is glancing impact not, brake control valve is not worked, non-compressed air in the compressed air brake cylinder, car brake is not worked, in addition, a part of pressurized air in the main air reservoir enters barometric regulator, when pressure reaches setting value, the off-load that pressurized air is finished air compressor through barometric regulator with regard to the unloader valve that enters air compressor is moved, and the interior air pressure of main air reservoir this moment just no longer raises.During automobile brake, brake control valve work, the pressurized air in the main reservoir tube enters the compressed air brake cylinder of each wheel by brake control valve, and car brake work produces brake action.
This gas circuit design, when automobile brake, particularly when the frequent lower long slope of mountain road, chaufeur is in order to control the speed of a motor vehicle, usually adopt extension low gear and utilize the driving engine auxiliary braking, but often the slope is grown suddenly, the Jake brake undercapacity, and must often step on brake pedal, thereby cause the brake system load to increase, drg generates heat easily, influences braking safety, also increases the wearing and tearing of braking system part simultaneously.
Summary of the invention
The utility model provides a kind of and strengthens the air compressor running resistance at glancing impact just in order to overcome above-mentioned deficiency, improves the braking system gas circuit of the improved air break automobile of the auxilliary moving brake action of driving engine, reaches and improves the safer purpose of running car.Main innovation is to increase by a gascollecting cap cylinder in pipeline, sets up two electromagnetic valves and a pressure-modulation valve simultaneously in pipeline.Specifically implement like this: the braking system gas circuit of improved air break automobile, air compressor, wet air receiver, main air reservoir pipeline successively are communicated with, main air reservoir one road pipeline is connected to the brake control valve that is communicated with each compressed air brake cylinder, another road plumbing connection one barometric regulator is connected the unloader valve of air compressor, it is characterized in that being provided with on the pipeline between air compressor and wet air receiver a two-position three way magnetic valve A, two-position three way magnetic valve A is the plumbing connection gascollecting cap cylinder in addition; Be provided with a two-position three way magnetic valve B on the pipeline between main air reservoir and barometric regulator again, two-position three way magnetic valve B is communicated with atmosphere in addition; Two-position three way magnetic valve A and two-position three way magnetic valve B are by the switch control that is located on the brake pedal.
When glancing impact not, the pressurized air that air compressor pumps enters wet air receiver through two-position three way magnetic valve A, after carrying out oil separation, clean pressurized air enters main air reservoir, a part of pressurized air in the main air reservoir enters barometric regulator by two-position three way magnetic valve B, when pressure reached setting value, pressurized air was finished the off-load action of air compressor with regard to the unloader valve that enters air compressor.
Work as glancing impact, step on brake pedal, the commutation of switching on simultaneously of switch connection on it, two-position three way magnetic valve A and two-position three way magnetic valve B is for electromagnetic valve B, cut off the gas circuit of main air reservoir and barometric regulator after the commutation, and the pipeline of barometric regulator is communicated with atmosphere, and the blow off valve of barometric regulator is opened, and the air in the unloader valve is through the blow off valve exhaust to atmosphere of barometric regulator, unloader valve quits work, and air compressor is resumed work; Simultaneously, for electromagnetic valve A, the pressurized air that commutation back air compressor pumps can only enter gascollecting cap cylinder, pressure in the gascollecting cap cylinder constantly raises, thereby the running resistance of air compressor is increased, also just cause the engine running resistance to increase, made the auxilliary moving brake action of driving engine strengthen, improved the brake safe performance.
Safe in operation for further assurance equipment can be provided with a pressure-modulation valve on gascollecting cap cylinder, when pressure was elevated to design value, pressure-modulation valve was opened exhaust pressure relief; In this gas circuit, because braking makes the pressurized air in the main air reservoir that consumption be arranged, best method is to be equipped with pressure-modulation valve pipeline connection main air reservoir again in the gascollecting cap cylinder exit, when the difference of pressure in the gascollecting cap cylinder and main air reservoir internal pressure reaches setting value, pressure-modulation valve is opened, part pressurized air is replenished air feed through pressure-modulation valve to main air reservoir, and the pressure with in the regulation and control gascollecting cap cylinder has guaranteed the gascollecting cap cylinder safe operation.
The utility model is by setting up electromagnetic valve and gascollecting cap cylinder in the gas circuit, glancing impact has changed the pressurized air flow direction that air compressor pumps, thereby increased the running resistance of air compressor, also promptly increased the running resistance of driving engine, driving engine auxiliary braking effect strengthens, alleviate the wearing and tearing of car brake, prolonged the service life of drg, improved running safety.
