Oil pump, control valve group and the rod chamber of oil cylinder and rodless cavity, inputted the fluid in fuel tank extremely by control valve group regulation oil pump
The rod chamber of oil cylinder or the amount of rodless cavity.
After using such structure, originally can drop alterable height stiffness helix spring suspension system have the advantage that 1, car
Height adjustable, so having higher by property, particularly to enter the spatial altitude such as culvert or transporter limited for vehicle
In space, this advantage is more prominent；2, damping can adjust according to highway or cross-country pattern, so corresponding different road conditions,
Suspension has different rigidity and damping, improves the handling of vehicle, adds the comfort of driving.
For the clearer technology contents understanding the present invention, below originally will can drop alterable height stiffness helix spring and hang
System is referred to as this suspension.
The control valve group of this suspension includes the first electricity proportional throttle valve, the second electricity proportional throttle valve and electromagnetic switch
Valve, the first electricity proportional throttle valve rod chamber by pipeline connection oil cylinder, the second electricity proportional throttle valve is also by pipeline connection oil
The rod chamber of cylinder, the first electricity proportional throttle valve and the second electricity proportional throttle valve connect with solenoid directional control valve respectively, solenoid directional control valve
It is connected with fuel tank, oil pump by pipeline；After using such structure, the structure making control valve group is the most reasonable, can meet this
The use requirement of suspension.
It is additionally provided with overflow on pipeline between first electricity proportional throttle valve and the second electricity proportional throttle valve of this suspension
Valve.
Acceleration transducer and height sensor are installed on the vehicle frame of this suspension；After using such structure, permissible
The driving information of Real-time Collection vehicle, is easy to dynamically adjust the height of this suspension according to above-mentioned information.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of this suspension embodiment.
Detailed description of the invention
As shown in Figure 1
This suspension includes that oil cylinder 1, damping spring 2 and fluid control assembly.
The lower end of oil cylinder 1 cylinder barrel is hinged on lower swing arm 8, the upper end thereof of oil cylinder 1 piston rod on vehicle frame 7, damping bullet
Spring 2 is sleeved on outside oil cylinder 1, and damping spring 2 two ends bear against on lower swing arm 8 and vehicle frame 7, and vehicle frame 7 is installed acceleration
Sensor 3 and height sensor 4.
Fluid controls assembly and then includes fuel tank 51, oil pump 52 and control valve group.
Control valve group include again first electricity proportional throttle valve 53a, second electricity proportional throttle valve 53b, solenoid directional control valve 53c and
Overflow valve 53d, the first electricity proportional throttle valve 53a rod chamber by pipeline connection oil cylinder 1, the second electricity proportional throttle valve 53b is also
By the rod chamber of pipeline connection oil cylinder 1, the first electricity proportional throttle valve 53a and the second electricity proportional throttle valve 53b respectively with electromagnetism
Reversal valve 53c connects, and solenoid directional control valve 53c is connected with fuel tank 51, oil pump 52 by pipeline, and control valve group control oil pump 52 is by oil
Hydraulic oil input in case 51 throttles to rod chamber or rodless cavity, the first electricity proportional throttle valve 53a and the second electricity ratio of oil cylinder 1
Overflow valve 53d it is additionally provided with on pipeline between valve 53b.
When vehicle transport pattern；
Solenoid directional control valve 53c obtains electric, being driven by motor of oil pump 52, then oil pump 52 is got hydraulic oil and entered control valve
Group arrives the rod chamber of oil cylinder 1, makes oil cylinder 1 retract, and oil cylinder 1 rodless cavity hydraulic oil passes through control valve group oil return simultaneously, and oil cylinder 1 contracts
Compression shock absorption spring 2 while Huiing, makes the height reduction of whole vehicle.
Height sensor 4 detects the vehicle frame 7 distance to lower swing arm 8 in real time, when this distance arrives setting value, makes oil pump 52
Motor 6 stop, then the volume of hydraulic oil in the rod chamber of the locked oil cylinder of solenoid directional control valve 53c 1, makes oil cylinder 1 be maintained at this position
Put.
If this position needs to keep the long period, it is possible to use the machinery on solenoid directional control valve 53c is locked, even if complete machine
Flame-out, solenoid directional control valve 53c can also be maintained to obtain current potential for a long time.
Vehicle is when road running, and the first electricity proportional throttle valve 53a and the second electricity proportional throttle valve 53b obtains one group of electric current
Or magnitude of voltage, making the oil return resistance of oil cylinder 1 rod chamber diminish, so that hanging deliquescing, i.e. there is less rigidity, simultaneously oil cylinder
Have after 1 compression and comparatively faster stretch out speed.
Vehicle is when cross-country run, and the first electricity proportional throttle valve 53a and the second electricity proportional throttle valve 53b obtains one group of electric current
Or magnitude of voltage, making the oil return resistance of oil cylinder 1 rod chamber become big, so that hanging hardening, i.e. there is bigger rigidity, simultaneously oil cylinder
Have after 1 compression and comparatively faster stretch out speed.So vehicle is through continuous potted road surface, and the vibration of vehicle can subtract relatively
Few, improve the handling of vehicle, increase the comfortableness driven.
It addition, above-mentioned several driving mode, this suspension can pass through PLC control system output signal, and the most anti-
It is fed on the touch control screen that vehicle operating is indoor, convenient use.
Above-described is only one embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, under the premise without departing from the principles of the invention, it is also possible to make some modification and improvement, these also should be regarded as belonging to this
Bright protection domain.
