Abstract

The utility model relates to an electrically-controlled vehicle descending system of an air suspension system. The electrically-controlled vehicle descending system comprises an air reservoir. The air outlet of the air reservoir is connected with a one-way valve. The outlet of the one-way valve is provided with three branch circuits in parallel, and the three branch circuits are respectively communicated with a first group of air bags on a front suspension frame, a second group of air bags and a third group of air bags on a rear suspension frame through a first altitude valve, a second altitude valve and a third altitude valve. A first magnetic valve is arranged between the first altitude valve and the first group of air bags, a second magnetic valve is arranged between the second altitude valve and the second group of air bags, and a third magnetic valve is arranged between the third altitude valve and the third group of air bags. The first magnetic valve, the second magnetic valve and the third magnetic valve are respectively connected with a magnetic valve control switch. According to the technical scheme, when the height of a vehicle needs to be lowered, the magnetic valve control switch is pressed, at this time, compressed air in the first group of air bags, compressed air in the second group of air bags and compressed air in the third group of air bags pass through a first overflow valve, a second overflow valve and a third overflow valve and are exhausted from the exhaust port of the first magnetic valve, the exhaust port of the second magnetic valve and the exhaust port of the third magnetic valve. Therefore, the height of the air bags is lowered, the height of the whole vehicle is lowered, and the vehicle can pass though lower buildings.

Description

The vehicle descending system of automatically controlled Pneumatic Suspension

Technical field

The utility model relates to a kind of vehicle descending system of automatically controlled Pneumatic Suspension.

Background technology

Raising along with living standards of the people, for the big bus of going sightseeing, generally at roof, install an air-conditioner, bodywork height is compared with vehicle in the past, and certain increase is arranged, and in some cities historical ancient city particularly, the height of some buildings is to design with reference to former height of car, along with the increase of height of car, cause vehicle to pass, in order to make vehicle, pass through smoothly, the height of vehicle must descend, and increases the vehicle lifting function.At present, passenger vehicle Pneumatic Suspension commonly used itself is not with elevating function, if vehicle need to increase elevating function, two kinds of forms is arranged usually: a kind of is mechanical type air bag jacking system, the parts such as the valve class that this jacking system need increase are more, and pipeline connects more complicated; Another kind is automatically controlled air bag jacking system, and this jacking system gas circuit is connected more complicated with circuit, and demarcation and test need special software.These two kinds of forms are all to use external import element, and price is all higher; Simultaneously the vehicle lifting function in actual use substantially need not, cause function waste, also increased car owner's economical burden simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of vehicle descending system of automatically controlled Pneumatic Suspension, and this system realizes rising or the reduction of car load height by the control of the air feed to air bag or exhaust, make vehicle can pass through low building.

For achieving the above object, the utility model has adopted following technical scheme: comprise air receiver, the air extractor duct of described air receiver is connected with check valve, the outlet of described check valve is set up in parallel three branch roads, described three branch roads are respectively by first, second, first group of air bag on third high bottom valve and front suspension, on rear suspension second, the 3rd group of air bag is connected, described first, second, third high bottom valve and first, second, be respectively equipped with first between the 3rd group of air bag, second, the 3rd electromagnetic valve, described first, second, the 3rd electromagnetic valve is connected with the solenoid control switch respectively.

Be respectively equipped with first, second, third by pass valve between described first, second, third levelling valve and first, second, third electromagnetic valve.

As shown from the above technical solution, when native system need to reduce height at vehicle, press the solenoid control switch, at this moment the pressure gas in first, second, third group of air bag is through first, second, third by pass valve, and discharge by the exhausr port of first, second, third electromagnetic valve, make thus the air bag height reduce, thereby the car load height is reduced, make the vehicle can be by the building of low clearance.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

The vehicle descending system of a kind of automatically controlled Pneumatic Suspension as shown in Figure 1, comprise air receiver 1, the air extractor duct of air receiver 1 is connected with check valve 2, the outlet of check valve 2 is set up in parallel three branch roads, article three, branch road is respectively by first, second, third high bottom valve 3, 4, 5 with front suspension on first group of air bag 6, on rear suspension second, the 3rd group of air bag 7, 8 are connected, first, second, third high bottom valve 3, 4, 5 and first, second, the 3rd group of air bag 6, 7, be respectively equipped with first between 8, second, the 3rd

electromagnetic valve

9, 10, 11, first, second, the 3rd

electromagnetic valve

9, 10, 11 are connected with solenoid control switch 12 respectively.

Further, be respectively equipped with first, second, third by

pass valve

13,14,15 between first, second, third levelling valve 3,4,5 and first, second, third electromagnetic valve 9,10,11.The effect that first, second, third by

pass valve

13,14,15 is set is according to actual needs, to set the height that air bag need to descend.

Three branch roads of the present utility model are three branch roads arranged side by side, and its working process is identical, below first group of air bag of take on front suspension describe as example:

When vehicle normally moves, the pressurized air in air receiver 1 is passed through check valve 2, then gives first group of air bag 6 air feed through the first levelling valve 3, the first electromagnetic valve 9, the first by pass valve 13 respectively, guarantees normally travelling of vehicle; When running into passing through building lower than height of car, press solenoid control switch 12, at this moment the pressurized air in first group of air bag 6 is discharged through the first by pass valve 13 and by the exhausr port of the first electromagnetic valve 9, at this moment the height of first group of air bag 6 descends, the car load height is descended, at this moment, but vehicle low speed is by passing through object, after vehicle passes through, press solenoid control switch 12, pressurized air in air receiver 1 gives first group of air bag 6 inflations fast, and first group of air bag 6 reaches normal design height, normal vehicle operation.

Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
