Abstract
The invention discloses a tractor air suspension height adjuster which comprises an air storage tank, height valves, change-over valves, electromagnetic height control valves and air springs. The air storage tank and the height valves are connected with the electromagnetic height control valves, and the height valves are connected with the change-over valves which are connected with the air springs. The tractor air suspension height adjuster has the advantages of simple structure, capability of automatically adjusting height of a tractor and convenience and quickness in using and mounting.
Description
Technical field
The present invention relates to a kind of height lifting device, more precisely a kind of tractor truck air suspension height arm control.
Background technology
As everyone knows, all tractor trucks on the market have headstock without compartment, generally when being connected with trailer, tractor truck need to be stepped back, by the height of manual regulation tractor truck, the final position that accurately snaps into trailer hinged disk, this method needs to attempt accurately snapping into position just now several times in the process connecting, and time-consumingly takes a lot of work again.
For these reasons, designing a kind of device that can automatically regulate tractor truck height is to be badly in need of a technical matters solving.
Summary of the invention
The present invention solves the existing technical matters of prior art, thereby tractor truck air suspension height arm control a kind of simple in structure, convenient to use is provided.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of tractor truck air suspension height arm control, it comprises storage tank, levelling valve, change-over valve, electromagnetism height-control valve and air bellow, described storage tank is connected with electromagnetism height-control valve with levelling valve, described levelling valve is connected with change-over valve, described change-over valve is connected with air bellow, described electromagnetism height-control valve has electromagnetism height-control valve A and electromagnetism height-control valve B, electromagnetism height-control valve A and electromagnetism height-control valve B intercommunication, described change-over valve comprises change-over valve A and change-over valve B, change-over valve A and change-over valve B intercommunication, the two ends of described electromagnetism height controller are wound with respectively rising coil and reduce coil, described change-over valve can be automatic switching valve or manual switching valve.
Therefore the advantage of tractor truck air suspension height arm control of the present invention is, simple in structure, can automatically regulate tractor truck height, easy to install and use quick.
Accompanying drawing explanation
Fig. 1 is the gas circuit schematic diagram of tractor truck air suspension height arm control of the present invention;
Wherein,
1, storage tank; 2, levelling valve;
3, change-over valve; 4, electromagnetism height-control valve; 5, air bellow
44, rising coil; 45, reduce coil.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of simple in structurely, can automatically regulate tractor truck height, tractor truck air suspension height arm control convenient to use.
As shown in Figure 1, a kind of tractor truck air suspension height arm control, it it comprise storage tank 1, levelling valve 2, change-over valve 3, electromagnetism height-control valve 4 and air bellow 5, described storage tank 1 is connected with electromagnetism height-control valve 4 with levelling valve 2, described levelling valve 1 is connected with change-over valve 3, described change-over valve 3 is connected with air bellow 5, described electromagnetism height-control valve 4 has electromagnetism height-control valve A and electromagnetism height-control valve B, electromagnetism height-control valve A and electromagnetism height-control valve B intercommunication, described change-over valve 3 comprises change-over valve A and change-over valve B, change-over valve A and change-over valve B intercommunication, the two ends of described electromagnetism height-control valve 4 are wound with respectively rising coil 44 and reduce coil 45, described change-over valve 3 can be automatic switching valve or manual switching valve.
When tractor truck does not need to regulate height, levelling valve is connected with change-over valve, electromagnetism height-control valve is not worked, in the time the height of tractor truck need to being regulated, regulate change-over valve to be connected with electromagnetism height-control valve, by remote controller, connect the rising coil on electromagnetism height-control valve or reduce coil, thereby realizing the regulating effect of tractor truck height.
