Abstract
Adjustable air pressure sensing circuit switch is used to control a solenoid valve so as to control on and off of the air manifold passage and to distribute compressed air automatically.
Description
The title of 1 invention: automatic control method for distributing compressed air
2 technical field that the present invention belongs to:
The invention relates to and utilize adjustable air pressure switch of induction circuit that the pressurized air that air compressor produced in the automobile vapour pressure brake system is distributed automatically.
The technical background of 3 inventions:
(1) air compressor in the existing automobile pressure brake system when working to the anticyclonic pressure of setting, has operatorless device and makes its off-load.Shortcoming is: this moment, air compressor can not produce pressurized air again.(2) safety valve is discharged brake system with the part pressurized air automatically when the pressurized air of brake system surpasses the safety valve setting exhaust gas pressure.Shortcoming is: the air compressor of this moment must be to move under the exhaust gas pressure of safety valve setting.Can waste energy like this, and quicken to reduce mechanical life.
The purpose of 4 inventions:
The present invention mainly reaches following purpose: even but the automobile pressure brake system air pressure when reaching the influence value of setting air compressor stop automatically giving the air that contracts to the air tank voltage supply of brake system, and can under all or part of situation that sheds exhaust gas pressure, keep producing pressurized air.And the non-brake system of compressed-air supply that will be produced this moment.But the air pressure influence value according to automobile brake requirement set.
Another purpose provides a kind of method that makes the air compression off-load.
The content of 5 inventions:
With reference to Fig. 1 explanation
On the air pipe 7 between air compressor 1 and the breather check valve 2, manifold 4 is set, electromagnetic valve 5 is set on manifold 4, adjustable air pressure switch of induction circuit 6 is set on air tank 3.
The effect of 6 inventions:
As the above-mentioned pressurized air distribution device that constitutes, when but air tank 3 internal gas pressures reach the influence value of setting, adjustable air pressure switch of induction circuit 6 is connected conduction, make electromagnetic valve 5 conductions and action in good time, open the valve of manifold 4, the gas that this moment, air compressor 1 was produced can controllably be supplied with non-brake system by manifold 4.When but brake system air tank 3 air pressure dropped to the influence value that is lower than setting, adjustable air pressure switch of induction circuit 6 disconnected, and made electromagnetic valve 5 outages and closed manifold 4 in good time, and 1 in air compressor is to the brake system air feed.
The advantage of 7 inventions:
Advantage of the present invention (1): can make the air compressor off-load.Advantage (2): can be to non-brake system air feed.Advantage (3): can take into account air compressor simultaneously and unload severe and to non-brake system air feed.Advantage (4): the performance that need not change former brake system.
Claims (4)
1, the control method that a kind of pressurized air to air compressor produced that is used for brake system of car is distributed automatically.It is characterized in that: when 3 atmospheric pressure values of air tank in the brake system reached the influence value of setting, adjustable air pressure switch of induction circuit 6 conductings made electromagnetic valve 5 energisings action in good time open the passage of manifold 4.Make the pressurized air that this moment, air compressor 1 was produced supply with non-brake system by manifold 4.When but the air pressure of air tank 3 was lower than the influence value of setting, adjustable air pressure switch of induction circuit 6 disconnected, and made electromagnetic valve 5 outages also close the passage of manifold 4 in good time.This moment, air compressor 1 continuation was to the brake system air feed.
Utilize the logical of adjustable air pressure switch of induction circuit 6 control electromagnetic valve 5, outage, thereby the ventilation of control air menifold 4, and stuffiness.
2, according to claim 1) described manifold 4, it is characterized in that: manifold 4 is arranged on the air pipe 7 between air compressor 1 and the breather check valve 2 and with air pipe 7 and is communicated with.
3, according to claim 1) described electromagnetic valve 5, it is characterized in that: electromagnetic valve 5 is arranged on the manifold 4, and effect is air flue logical, disconnected in the control air menifold 4.
4, according to claim 1) described adjustable air pressure inductive switch 6, it is characterized in that: its induction opening is communicated with air tank 3.But the induction air pressure value can be adjusted setting according to brake request.
