Through type trailing link, the hydro pneumatic suspension device include：Oil pressure sensor, hydro pneumatic suspension cylinder, accumulator, six rib holes, circle
Arc connecting table, draft platform, the oil pressure sensor are mounted on hydro pneumatic suspension cylinder, and oil pressure sensor can monitor oil gas in real time
The variation of oil pressure in suspension cylinder to adjust the oil pressure of hydro pneumatic suspension cylinder in real time by the way that collected signal is transmitted to controller
Size, the accumulator and six rib holes pass through shaft hole matching, the circle by shaft hole matching, six rib hole with circular arc connecting table
Arc connecting table is mounted on draft platform.
Further, the car body coordinates with convex connected unit, the convex connected unit and hydro pneumatic suspension cylinder, the wheel hub
It is bolted together with connection hub shell, the hub shell welds together with draft platform, and the hemispherical Shell is matched with connection hub shell
It closes, the preceding bridge is coordinated with hemispherical Shell by bolt, and the rear axle and through type trailing link are described straight by shaft hole matching
General formula trailing link, by shaft hole matching, when vehicle braking, quickly average load can prevent rollover phenomenon with preceding bridge
Generation.
The beneficial effects of the utility model：Simple in structure, oil pressure sensor is mounted on hydro pneumatic suspension cylinder, cropper work
When cause the stress of hydro pneumatic suspension cylinder to change due to the variation of working environment, can be detected in real time by oil pressure sensor
The information of acquisition is transmitted to controller by the size of oil pressure in hydro pneumatic suspension cylinder, oil pressure sensor, and controller is according to being set in advance
Program realize the independent-liftings of 4 hydro pneumatic suspension cylinders, it can be achieved that automatic leveling, avoids car body from turning on one's side, protection operator
The life security of member.

Specific implementation mode
A kind of car body based on agricultural harvesting machinery of the utility model is adjusted automatically with reference to Figure of description 1 to attached drawing 5
Flat probe device, is described in detail below.
A kind of car body automatic leveling probe device based on agricultural harvesting machinery, including car body 1, convex connected unit 2, oil gas
Draft hitch, wheel hub 9, connection hub shell 10, hemispherical Shell 11, rear axle 12, preceding bridge 13, through type trailing link 14, the oil gas hanging
Rack device includes：Oil pressure sensor 3, hydro pneumatic suspension cylinder 4, accumulator 5, six rib holes 6, circular arc connecting table 7, draft platform 8, the oil
Pressure sensor 3 is mounted on hydro pneumatic suspension cylinder 4, and oil pressure sensor 3 can monitor the change of oil pressure in hydro pneumatic suspension cylinder 4 in real time
Change, by the way that collected signal is transmitted to controller, to adjust the size of the oil pressure of hydro pneumatic suspension cylinder 4, the accumulator 5 in real time
With six rib holes 6 by shaft hole matching, with circular arc connecting table 7 by shaft hole matching, the circular arc connecting table 7 is pacified in six rib hole 6
On draft platform 8.
Further, the car body 1 coordinates with convex connected unit 2, the convex connected unit 2 and hydro pneumatic suspension cylinder 4, described
Wheel hub 9 is bolted together with connection hub shell 10, and the hub shell 10 welds together with draft platform 8, the hemispherical Shell
11 coordinate with connection hub shell 10, and the preceding bridge 13 is coordinated with hemispherical Shell 11 by bolt, the rear axle 12 and through type longitudinal thrust
For bar 14 by shaft hole matching, the through type trailing link 14 can when vehicle braking by shaft hole matching with preceding bridge 13
Quick average load prevents the generation of rollover phenomenon.
When work, with the variation of harvest machine operation landform, the stress of 4 hydro pneumatic suspension cylinders is caused also to differ, to
The barycenter run-off the straight for leading to complete machine can be monitored respectively in real time by the oil pressure sensor on each hydro pneumatic suspension cylinder
Oil pressure value in each hydro pneumatic suspension cylinder is fed back to controller by the size of oil pressure in a hydro pneumatic suspension cylinder, oil pressure sensor, control
Device processed enters the uninterrupted of each hydro pneumatic suspension cylinder by the program write come independent control, to reach each oil gas hanging
The independent-lifting of frame cylinder finally realizes that the barycenter of complete machine is restored to equilbrium position, to realize automatic leveling.
Above description is only a specific implementation of the present invention, those skilled in the art are new in this practicality
In the range of type discloses, the variation that can be readily occurred in should be covered within the scope of the utility model.
