Abstract
The utility model discloses an air suspension height adjuster for a towing tractor. The adjuster comprises an air storage tank, height valves, change-over valves, electromagnetic height control valves and air springs, wherein the air storage tank is connected with the height valves and the electromagnetic height control valves; the height valves are connected with the change-over valves; and the change-over valves are connected with the air springs. The adjuster has the following advantages that the adjuster has simple structure, can automatically adjust the height of the towing tractor and is convenient and fast to use and install.
Description
Technical field
The utility model 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 the compartment, generally when being connected with trailer, tractor truck need to be stepped back, height by the manual regulation tractor truck, the final position that accurately snaps into the trailer hinged disk, this method need to attempt accurately snapping into the position just now several times in the process that connects, and time-consumingly take a lot of work again.
For these reasons, a kind of device that can automatically regulate the tractor truck height of design is a technical matters being badly in need of solution.
The utility model content
The utility model mainly is to solve 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 utility model 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 the 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-control valve are wound with respectively the rising coil and reduce coil, and 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 utility model is, and is simple in structure, can automatically regulate the tractor truck height, easy to install and use quick.
Description of drawings
Fig. 1 is the gas circuit schematic diagram of tractor truck air suspension height arm control of the present utility model;
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 preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
It is a kind of simple in structure that the utility model provides, and can automatically regulate the 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 the electromagnetism height-control valve with levelling valve 2 and is connected, described levelling valve 2 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, and 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, the electromagnetism height-control valve is not worked, in the time the height of tractor truck need to being regulated, regulating change-over valve is connected with the electromagnetism height-control valve, connect the rising coil on the electromagnetism height-control valve or reduce coil by remote controller, thereby realize the regulating effect of tractor truck height.
