Abstract
The utility model discloses air suspension height control system, including the air reservoir, with the mechanical type altitude valve of air reservoir intercommunication to and with the communicating air spring of altitude valve, wherein, have the solenoid valve between altitude valve and air spring, have the solenoid valve switch that links to each other with the solenoid valve in the driver's cabin. The utility model discloses air suspension height control system, through filling, the gassing of solenoid valve control air spring, the trailer is taken off with the main car and is hung in-process wheel casing and the collision of noninterference in trailer carriage bottom, prevents that the wheel casing from damaging, and simultaneously, convenient operation, the driver just can keep the frame at the arbitrary height of air spring stroke allowed range in the driver's cabin.
Description
Technical field
The utility model relates to airsuspension system, the airsuspension system of especially moderate, heavy tractor-truck.
Background technology
At present, airsuspension system has obtained application on automobile, and uses airsuspension system, can realize that vehicle is consistent at sky, laden height.The mechanical type levelling valve is installed, to realize on the existing vehicle to vehicle sky, laden height control between air tank and air bellow.The tractor-truck of back airsuspension system equipment mechanical type levelling valve, when trailer separates with main car, owing to set out moment, load on axle journals becomes the approximate vanishing state of load from fully loaded load condition behind the main car, be that the rear axle load change is very big, and mechanical type levelling valve adjusting height of car needs time and process, air bellow is pressed in the height that at full load stores and is had little time to discharge, with vehicle frame jack-up, the vehicle frame rising drives the trailing wheel wheel cover that is connected on it and raises together, wheel cover and bottom, trailer compartment interfere collision, cause wheel cover to damage.
Summary of the invention
Wheel cover and trailer compartment bottom interferes collision in trailer and the main car dislodging process in order to solve, the problem that causes wheel cover to damage, the utility model provide the air suspension height control system that does not interfere bottom the wheel cover and trailer compartment in a kind of trailer and the main car dislodging process.
The utility model air suspension height control system comprises air tank, the mechanical type levelling valve that is communicated with air tank, and the air bellow that communicates with levelling valve, wherein, between levelling valve and air bellow, electromagnetic valve is arranged, the electromagnetic valve switch that links to each other with electromagnetic valve is arranged in operator's compartment.
Electromagnetic valve switch has three control positioies: one is off position, and one is to stop the holding position, and one is deflation position.
When vehicle was in the cruising state, electromagnetic valve switch was in the closed position, and promptly electromagnetic valve is in no electric normal open state, was realized the adjusting of chassis frame height by the levelling valve control system.
When main car separates with trailer, the process of promptly seting out, pressing electromagnetic valve switch makes it be in deflation position, the inlet close of electromagnetic valve, Exhaust Open, inlet close has just temporarily been isolated air tank and levelling valve, makes the levelling valve of this moment inoperative, and Exhaust Open makes the high pressure gas in the air bellow pass through the exhausr port exhaust to atmosphere of electromagnetic valve.When electromagnetic valve switch being positioned at stop the holding position, electromagnetic valve inlet and outlet mouth is all closed, and the chassis frame height is realized seting out smoothly by locking.
In sum, the beneficial effects of the utility model are as follows:
The utility model air suspension height control system, between levelling valve and air bellow, electromagnetic valve is installed, can filling, exitting by the solenoid control air bellow, wheel cover and trailer compartment bottom does not interfere collision in trailer and the main car dislodging process, prevents that wheel cover from damaging, simultaneously, easy to operate, chaufeur just can remain on vehicle frame the arbitrary height in the air bellow stroke tolerance band in operator's compartment, easy to operate, the efficient height.
Below by the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is an air suspension height control system schematic diagram.
The specific embodiment
Referring to Fig. 1, present embodiment air suspension height control system, comprise air tank 1, the mechanical type levelling valve 2 that is communicated with air tank 1, and the air bellow 4 that communicates with levelling valve 2, wherein, between levelling valve 2 and air bellow 4, electromagnetic valve 3 is arranged, the solenoid control switch 5 that links to each other with electromagnetic valve 3 is arranged in operator's compartment.
When vehicle was in the cruising state, electromagnetic valve switch 5 was in the closed position, and promptly this moment, electromagnetic valve 3 was in no electric normal open state, was realized the adjusting of chassis frame height by levelling valve 2 control system.
When main car separates with trailer, the process of promptly seting out, pressing electromagnetic valve switch 5 makes it be in deflation position, the inlet close of electromagnetic valve 3, Exhaust Open, inlet close has just temporarily been isolated air tank 1 and levelling valve 2, makes the levelling valve of this moment inoperative, and Exhaust Open makes the high pressure gas in the air bellow 4 pass through the exhausr port exhaust to atmosphere of electromagnetic valve 3.When electromagnetic valve switch 5 being positioned at stop the holding position, electromagnetic valve 3 inlet and outlet mouths are all closed, and the chassis frame height is realized seting out smoothly by locking.
Present embodiment air suspension height control system, between levelling valve and air bellow, electromagnetic valve is installed, can filling, exitting by electromagnetic valve ACTIVE CONTROL air bellow, wheel cover and trailer compartment bottom does not interfere collision in trailer and the main car dislodging process, prevents that wheel cover from damaging, simultaneously, easy to operate, chaufeur just can remain on vehicle frame the arbitrary height in the air bellow stroke tolerance band in operator's compartment, easy to operate, the efficient height.
Claims (2)
1, a kind of air suspension height control system, comprise air tank, the levelling valve that is communicated with air tank, and the air bellow that communicates with levelling valve, it is characterized in that: between described levelling valve and described air bellow, electromagnetic valve is arranged, the electromagnetic valve switch that links to each other with described electromagnetic valve is arranged in operator's compartment.
2, air suspension height control system according to claim 1 is characterized in that: described electromagnetic valve switch has three control positioies, is respectively off position, stops holding position and deflation position.
