Work forms, and materials are convenient, simple process.The slideway that steel plate is welded into rectangular in cross-section can also be used in certain counterweight sliding slot 4.
The drive dynamic control device includes the pressure sensor 8 on the steering cylinder 12 being arranged on farm tractor front axle 1, institute
The structure and principle for stating steering cylinder 12 are well-known technique, and details are not described herein.Current axis institute is loaded when becoming larger, front driving wheel
Because the frictional force that load generates can become difficult to turn to, this needs biggish pressure being macroscopically shown as the steering cylinder 12
Can just front driving wheel be driven to rotate, the pressure that the pressure sensor 8 can measure on steering cylinder 12 becomes larger, before knowing with this
The load that axis is subject to becomes larger；Otherwise similarly.
The pressure sensor 8 is connected with controller 9, and the controller 9 controls the sliding driving device.The control
What device 9 was well known to those skilled in the art, details are not described herein.Sliding driving device described in the present embodiment includes sliding driving
Cylinder 11, the sliding driving cylinder 11 are connected with electromagnetic switch regulating valve 10, and the electromagnetic switch regulating valve 10 is connected with high pressure liquid
The set of pumps on tractor can be used in body feeding, the highly pressurised liquid feedway, this is those skilled in the art institute
Well known, details are not described herein and is being not shown in the figure.The controller 9 controls the electromagnetic switch regulating valve 10.Certain institute
Stating sliding driving device can also be used the structure including electric pushrod, and the controller 9 directly controls stretching for the electric pushrod
It receives.
Drive dynamic control device described in certain the present embodiment can also be include manual reverse of direction regulating valve, the manual reverse of direction is adjusted
Valve is connected with highly pressurised liquid feedway, i.e. driver can also drive manually the clump weight component 3 according to direct feel
It slides to achieve the purpose that adjust load distribution.
The working principle of the present embodiment are as follows: when tractor connects outfitting tool, equipment is made because of gravity or because of cultivation etc.
Industry by soil reaction force when, equipment can be applied to one reaction force of tractor body, as the gravity of equipment to draw
Machine entirety center of gravity moves back, and Tractor Front Axle load becomes smaller, and front driving wheel steering resistence becomes smaller at this time, the steering at preceding bridge 1
The pressure that the driving of oil cylinder 12 turns to just becomes smaller, and the pressure sensor 8 can measure pressure value in real time, can be pre- on the controller 9
The minimum and peak of the pressure sensor 8 are first set, i.e., when pressure value is between minimum and peak, antero posterior axis is carried
Lotus is relatively reasonable, can guarantee effective traction；When the pressure sensor 8 described in the above situation measures pressure value lower than minimum,
I.e. capable of emitting signal, the controller 9 controls the electromagnetic switch regulating valve 10 and the sliding driving cylinder 11 is stretched out, described
Clump weight component 3 is forward away from tractor body, so that tractor entirety center of gravity moves forward, Tractor Front Axle load is become larger,
The pressure sensor 8 measures pressure value and also becomes larger, when pressure value is between minimum and peak, the control
Device 9 controls the electromagnetic switch regulating valve 10 and 11 stopping of sliding driving cylinder is acted, the load quilt of tractor antero posterior axis
It adjusts to a relatively reasonable state, tractor can realize effective traction；When removing outfitting tool, before tractor center of gravity
It moves, the pressure value that the pressure sensor 8 measures at this time becomes larger, and issues signal and carries out opposite action, until pressure value is restored to
Between minimum and peak；The clump weight component 3 described in this way can automatically adjust load point according to Tractor Front Axle load change
Match.The present embodiment can also be used manually, and with operator's direct feel, the clump weight component 3 is reached suitable distance,
So that tractor center of gravity is maintained in a relatively stable position range, front and back axle load can also be in relatively reasonable state model
In enclosing, when such case being suitable for outfitting tool to soil progress operation by continually changing soil reaction force.
The present embodiment structure is simple, and cost is relatively low, has well solved tractor fore-aft loads unreasonable distribution and has caused to lead
Draw the case where going wrong, there is admirably promotional value.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
