(ECU) it is controlled, height adjusting function is perfect, but cost is very high and 2 complex operations；Second is tradition machinery formula, mainly
It is controlled by altitude valve, cost is low, but a height can only be preset, do not possess height adjusting function.
With the popularization of air suspension, the application scenario of suspension height regulatory function is more and more, for example：Tractor it is de-
Extension, bus drop height hung and got rid of and on-board and off-board, load-carrying vehicle adjusting height matching workbench etc., degree of recognition of the user to the function facilitated
More and more higher, but certain customers can not bear the cost pressure that electric-controlled type air suspension control system is brought.
Air suspension control system of the prior art, all only includes a kind of shaping modes, it is impossible to meet under various occasions
Regulation to suspension height.
The content of the invention
The problem of present invention can not adjust height for electric-controlled type air suspension cost height, tradition machinery formula air suspension,
A kind of mechanical bimodulus air suspension control system is provided, mechanical air suspension is possessed the height regulation of both of which
Function.
To achieve the above object, the technical solution used is：
A kind of mechanical bimodulus air suspension control system, including gas receiver 1, electromagnetic switch 2, two equilbrium positions
Altitude valve 3, handle control valve 4 and two air springs 5；Three gas outlets of described gas receiver 1 respectively with electromagnetic switch 2,
Two equilbrium position altitude valves 3, the air inlets of handle control valve 4 are connected, gas outlet and the left and right two of described electromagnetic switch 2
The control mouth of equilbrium position altitude valve 3 is connected, the gas outlets of two equilbrium position altitude valves 3 respectively with handle control valve 4 two
Individual air inlet is connected, and two gas outlets of handle control valve 4 are connected with the air spring 5 of left and right two respectively.
Described handle control valve 4 is a kind of five six logical mechanical valves, the direct control valve position change of handle.
The double flat weighing apparatus position height valve is a kind of altitude valve with control mouth, by changing control mouth pressure, is realized high
Bottom valve switches between two equilbrium positions.
The beneficial effects of the invention are as follows：
1st, comprising two kinds of height shaping modes, regulative mode and operating position are had nothing in common with each other, and both of which complements each other, can
Meet the regulation to suspension height under various occasions：The first pattern is adjusted by electromagnetic switch, can be adjusted and be remained to
The suspension height of two settings, is typically located in driver's cabin, can be operated under vehicle running state, simple and convenient；Second
Pattern is adjusted manually by handle control valve, can adjust any suspension height, is typically located at driving outdoor, can only stopped
Adjusted under car state, but height adjustment range is wide.
2nd, the system is simple in construction independent of electronic control unit, easy to operate, and cost is low.

Embodiment
Below in conjunction with brief description of the drawings, the present invention is described in further detail with embodiment.
Referring to Fig. 1, a kind of mechanical bimodulus air suspension control system, including gas receiver 1, electromagnetic switch 2, two
Equilbrium position altitude valve 3, handle control valve 4 and two air springs 5；Three gas outlets of described gas receiver 1 respectively with electricity
Magnetic switch 2, two equilbrium position altitude valves 3, the air inlets of handle control valve 4 are connected, the gas outlet of described electromagnetic switch 2 with
The control mouth of the equilbrium position altitude valve 3 of left and right two is connected, the gas outlets of two equilbrium position altitude valves 3 respectively with handle control
Two air inlets of valve 4 are connected, and two gas outlets of handle control valve 4 are connected with the air spring 5 of left and right two respectively.
Referring to Fig. 2 and 3, above-mentioned equilbrium position altitude valve 3 is a kind of altitude valve with control mouth, and control mouth pressure is less than
During 0.8Mpa, such as equilbrium position 1；When control mouth pressure is more than 0.8Mpa, such as equilbrium position 2.
Referring to Figure 4 and 5, above-mentioned handle control valve 4 is a kind of five six logical mechanical valves, the direct control valve position change of handle.
The mechanical bimodulus air suspension control system course of work of the present invention is as follows：
The present invention's includes two kinds of height shaping modes, and the first pattern is adjusted by electromagnetic switch, switchs and adjusts in such as Fig. 1
A is saved, electromagnetic switch may be arranged in driver's cabin.When switch is closed, altitude valve is design in equilbrium position 1, now suspension height
Highly；Switch is opened, and altitude valve is in equilbrium position 2, and now suspension height, which becomes, turns to the second height；According to actual needs, second
It highly may be configured as being higher or lower than design height.
Second of pattern is adjusted manually by handle control valve, and handle adjusts B in such as Fig. 1, and handle control valve 4 is typically arranged
Outdoor driving, when handle is located at III, altitude valve 3 is directly connected with air spring 5, and suspension height is adjusted by altitude valve 3；Hand
When handle is located at I, 21 mouthfuls of closings of outlet of equilbrium position altitude valve 3, air spring 5 and 3 mouthfuls of the exhaust of handle control valve 4 connect
Logical, suspension height is persistently reduced, and handle regulation stops keeping to II；When handle is located at V, 21 mouthfuls of passes of outlet of altitude valve 3
Close, air spring 5 is connected with gas receiver 1, and suspension height is persistently raised, handle regulation stops keeping to IV.
Altitude valve 3 is closed during due to second of shaping modes work, and the first shaping modes need to rely on altitude valve 3,
Therefore second of shaping modes is prior to the first shaping modes.I.e.：When adjusting B using handle, switch-mode regulation A can not be acted as
With；During using switch-mode regulation A, remain to adjust B using handle.
The first switch-mode regulation pattern of the present invention, is driving in-house operation, simple and convenient, but can only adjust high to second
Degree；Second of handle shaping modes, is driving field operation, freely adjustable suspension height.Both of which respectively has advantage and disadvantage, knot
Altogether, complement each other, the regulation to suspension height under various occasions can be met.
The mechanical bimodulus air suspension control system that the present invention is provided, on the premise of without using electronic control unit,
Mechanical air suspension control system is possessed the height adjusting function of both of which, meet the demand of certain customers, and greatly
Ground reduces cost.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, said structure should be all considered as belonging to
Protection scope of the present invention.
