The design can be improved on traditional ripe chassis technology, can rapidly form productivity；The design With three modules：Hydraulic lifting module, chassis varied angle module and rotation frame module；Hydraulic lifting module mainly utilizes liquid Pressure technology and sensor technology are balanced regulation to agricultural mechanical base plate above section, mainly include involved in the application 3, No. four hydraulic cylinders 4 of hydraulic cylinder of hydraulic cylinder 2, three of the No.1 hydraulic cylinder arrived 1, two；Chassis varied angle module is hydraulic lifting The companion module of module, because the free degree and mechanics problem, it is necessary to by the Scheduling Design on chassis to be variable, recycle the weight of agricultural machinery The function of initial alignment is played in the effect of power and positive stop lug boss, the No.1 hinge being mainly concerned with the utility model and No. two Hinge；Rotation frame module is the rotary freedom in another direction on chassis, is provided with damper, this module can when chassis it is anterior Point and partly have an angle along the horizontal plane afterwards, relate generally to rotating disk 6 in the utility model, No.1 damper 12, two Number damper 13, rotation frame module are combined with the effect of hydraulic lifting module center-of-gravity regulating and make up the four-wheel of suspension system jointly Grounding function, improve landform adaptability.

The utility model can utilize hydraulic lifting technology and maintain car body balance under complicated landform environment；Utilize rotation The torsion of frame strengthens four-wheel grounded capacity to strengthen landform adaptability.It is improved on the basis of traditional chassis, only need to be by zero Part position adaptability, which rearranges, can complete to improve, therefore, the transmission system on traditional chassis, driving system, steering and Brakes is not stated in detail.

In order to facilitate description, if agricultural machinery direction of advance is X-axis, perpendicular to the vertical to being Z plane for Y-axis, ground of X-axis. Relative to traditional chassis, it can simply be interpreted as having installed additional between anterior sub-chassis 7 and rear parts of chassis 8 and contain No.1 hinge The chassis varied angle module of chain and the rotation frame module for containing rotating disk.Have above chassis and contain No.1 hydraulic cylinder 1 Hydraulic lifting module.There is expansion connection 9 in front of chassis, there is provided distinct device installation site.

Hydraulic lifting system major part is 3, No. four hydraulic cylinders 4 of hydraulic cylinder of hydraulic cylinder 2, three of No.1 hydraulic cylinder 1, two With universal joint 10.The distribution of four hydraulic cylinders is as shown in Figure 1.It is respectively supported at the corner of vehicle body.Vehicle body is connected with hydraulic cylinder, liquid Cylinder pressure is connected with chassis again, and vehicle body is with chassis without connected.When gyro sensor detects a certain angle or while by low-lying Section and when being less than other, then hydraulic cylinder where the angle or the side can rise, and keep car body balance.The piston of No.1 hydraulic cylinder Bar is connected to universal joint 10, there is multiple rotary freedoms.Because four hydraulic cylinders are not in most cases in a practical situation Lift simultaneously, so there must be the rotary freedom around Y-axis；Frame module, anterior sub-chassis 7 and rear partial bottom are rotated due to existing Disk 8 has the relative rotation around X-axis, but vehicle body now can be considered with a steel disc, it is therefore necessary to has the rotation around X-axis free Degree.

Hydraulic cylinder piston rod is connected by summary two using universal joint with chassis herein.The cylinder body of No.1 hydraulic cylinder 1 It is connected with vehicle body, it is impossible to have relative motion.Because if being be hinged herein, then system is insufficient DOF system, and vehicle body has not Controllability, therefore in order to which control reliability must use attachment herein.Other hydraulic cylinders are equally connected.

Meanwhile four hydraulic cylinders are all placed vertically in initial position, then when an angle physical features be less than other angles, it is necessary to When this angle hydraulic cylinder rises, then now mechanism is in dead-centre position, and other three hydraulic cylinders prevent this equivalent to steel disc The motion of individual hydraulic cylinder.So the initial position of hydraulic cylinder must be inclined, and front and rear hydraulic cylinder can not tilt simultaneously To one side, because now vehicle body center of gravity may not can produce a very big power in the centre position of front and rear hydraulic cylinder to chassis Square, certain destruction is produced to vehicle body, does not meet mechanical requirements.Therefore tilted respectively to different directions before and after hydraulic cylinder.No.1 1, No. two hydraulic cylinder 2 of hydraulic cylinder turns forward, and 3, No. four hydraulic cylinders 4 of No. three hydraulic cylinders tilt backwards, and vehicle body center of gravity is protected as far as possible Hold in the centre position of 4 hydraulic cylinders.Now chassis varied angle module and rotation frame module are all the effects of being under pressure.Work as No.1 Hydraulic cylinder 1, No. two hydraulic cylinders 2 tilt backwards, No. three hydraulic cylinders 3, when No. four hydraulic cylinders 4 turn forward, although can also make car Body center of gravity, which is tried one's best, is maintained at the centre positions of 4 hydraulic cylinders, but now chassis varied angle module and rotation frame module be all by To pulling force effect, these modules are all resistance to compression not tensions, therefore so also do not meet mechanical requirements.So the design makes No.1 liquid Cylinder pressure 1, No. two hydraulic cylinders 2 turn forward, and No. three hydraulic cylinders 3, No. four hydraulic cylinders 4 tilt backwards, as shown in Figure 1.

Chassis varied angle module is mainly made up of No.1 hinge 5 and No. two hinges.Chassis varied angle module is hydraulic lifting The companion module of module.Because hydraulic cylinder one is connected with chassis by universal joint, one is connected with vehicle body.Therefore this is needed Module lifts to coordinate.

Such as：When No. three hydraulic cylinders 3 and No. four hydraulic cylinders 4 need to rise, by motion analysis, if chassis length is not Become, i.e., wheelbase is constant, and now No.1 hydraulic cylinder 1 and No. two hydraulic cylinders 2 need to shrink or continue to turn forward, if during this Vehicle body encounters chassis, and No.1 hydraulic cylinder 1 and No. two hydraulic cylinders 2 are restricted from continuing to shrink or continue to turn forward, then and three Number hydraulic cylinder 3 and No. four hydraulic cylinders 4 can not rise.Now, it is that wheelbase can just make No. three Hes of hydraulic cylinder 3 only to shorten chassis length No. four hydraulic cylinders 4 are completed to rise.Directly shorten chassis mechanism it is excessively complicated inadvisable, and need complexity control system and Dynamical system.Herein using simple motorless chassis varied angle module, essence is that chassis becomes wheelbase module in fact.No. three hydraulic pressure When cylinder 3 and No. four hydraulic cylinders need to rise and hindered by above-mentioned reason, have a component and be applied to No.1 hinge and No. two hinges On chain, the power of No. three hydraulic cylinders 3 and No. four hydraulic cylinders 4 makes No.1 hinge and No. two hinges open an angle.

Two part lower parts of No.1 hinge and No. two hinges have hinge to be connected, upper part limited location boss, in hydraulic pressure When cylinder does not all have power, due to the effect of vehicle body gravity, the positive stop lug boss of No.1 hinge and No. two hinges is compressed tightly against Together, initial position is limited.

Frame module is rotated by No.1 damper, No. two dampers, No.1 force transmission shaft, No. two force transmission shafts, rotating disk, No. two hinges Chain forms.

Rotation frame module designs for mountain topography.Suspension system very limited can only ensure that four-wheel connects simultaneously Ground, and the most tonnage of agricultural machinery is big, speed is slow, and the three-wheel ground connection of short time is likely to cause major accident.This module can be effective Avoid such event.

Such as：One jiao of physical features is significantly less than other three angles where No. three hydraulic cylinders 3, can be more beyond suspension system The scope of benefit, because No. three hydraulic cylinders 3 can be risen to maintain car body balance, therefore this angle where No. three hydraulic cylinders 3 can be by The downward active force given to No. three hydraulic cylinders 3.Now the rotation around X-axis can occur for No.1 force transmission shaft and No. two force transmission shafts, i.e., Rotation around X-axis, No. three place horn ring ground connection of hydraulic cylinder 3 occur for anterior sub-chassis 7 and rear parts of chassis 8.No.1 damper Stretching can be protruded by the tabular in rotating disk with No. two dampers, two dampers on opposite can be protruded by the tabular in rotating disk Compression is shaken with reducing.Tabular in rotating disk protrudes other components with this module and uses hard alloy steel, it is ensured that intensity foot It is enough.

No.1 force transmission shaft and No. two force transmission shafts are mutual by the pulling force between anterior sub-chassis 7 and rear parts of chassis 8 and pressure Transmit.

Chassis four-wheel drive energization schemes refer to Fig. 6, and four-wheel drive motor uses thulium permanent magnetism gear, and this is electronic Machine has the advantages that commutation ability is good, noise is low, efficiency high, high efficient district is wide, overload capacity is strong.

Full-vehicle control mainly completes full-vehicle control and energy management two parts function with EMS, is responsible for collection The operation information of the subsystems of vehicle simultaneously carries out monitor and diagnosis, maintains all batteries to be in optimum state, control charging Mode and dump energy is provided the responsibility such as shows, and implement following functions.
