The utility model can improve the traction of the land leveller effectively and greatly, and enlarge the using range. The device fully makes use of the weight of the leveller, that is, fully makes use of materials, thereby saving materials. The utility model is of simple technique, and easy popularization and application.
Description
Technical field
The utility model belongs to construction machinery and equipment to be improved, and particularly relates to a kind of road grader propons wheel fluid pressure drive device that can improve tractive force that has
Background technology
In present known road grader, its structure is by driving engine, driver's cab, back axle and tandem-driving bogie, afer bay, back axle wheel, forebay, propons, propons wheel, perching knife, and related components is organic connects into a complete machine.On this complete machine, have only the back axle wheel drive, and the propons wheel all there is not the actuating device setting owing to be subjected to the restriction of structure and body layout.Just because of this, the tractive force limit of road grader can only be that the back axle axle load multiply by tire and ground-surface adhesion value draws, and the propons wheel does not drive then and can not produce tractive force.In unit weight, the back axle axle load generally has only about 70% of complete machine weight, and all the other weight are propons.The tractive force limit of road grader can only realize that complete machine should have the maximum tractive force that allows about 70%, can find out obviously that therefrom its weak point is that the tractive force of road grader is subjected to certain limitation, haves much room for improvement and taps the latent power like this.
Summary of the invention
The utility model provides a kind of road grader propons wheel fluid pressure drive device that can improve tractive force that has for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Road grader propons wheel fluid pressure drive device comprises that forebay hanging perching knife, the two ends of propons are separately installed with the propons wheel, and associated parts such as driving pump, CD-ROM drive motor, drop-gear box, oil pipe and pipe fitting, organic connecting to form is characterized in that: the heart portion of single propons wheel increases the dress hydraulic drive mechanism respectively.
The utility model can also adopt following technical measures:
Described hydraulic drive mechanism can be that single propons wheel heart portion directly increases respectively 0～1000 rev/min CD-ROM drive motor is housed; The driving pump that is dragged by launched machine provides pressure oil by pipeline to them.
Described hydraulic drive mechanism, also can be in the A of propons frame portion, increase the CD-ROM drive motor that is equipped with 0～6000 rev/min and drag the drop-gear box rotation, its output shaft connected have the propons that on same direction of axis line, is provided with two-way rotation output, export with the two-way rotation of propons and connect the propons wheel respectively; The same driving pump that is dragged by launched machine provides pressure oil by pipeline to CD-ROM drive motor.
Advantage and the good effect that the utlity model has are:
Under complete machine weight unmodified condition, can increase substantially the tractive force of road grader effectively, enlarge this mechanical range of use; Make full use of complete machine weight, promptly made full use of material, realize economical with materials; Technology is simple, is easy to promotion and application.

Fig. 1 is the construction profile figure of road grader;
Fig. 2 is a kind of structure hydraulic principle schematic of the utility model;
Fig. 3 is the another kind of structure hydraulic principle schematic of the utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
This device comprises: the heart portion of single propons wheel 4 increases the dress hydraulic drive mechanism respectively.Embodiment has two, divides and does following detailed description.
Embodiment 1: see also Fig. 1,2, the forebay 1 of road grader is being hung for evening the perching knife of using on ground 2 out.The two ends of propons 3 respectively are equipped with propons wheel 4 respectively, and it is to be made of steel wheel hub and air-inflation tyre.Said hydraulic drive mechanism is installed by inboard heart portion in single propons wheel 4, is directly respectively to increase the CD-ROM drive motor 10 of adorning 0～1000 rev/min of high pulling torque respectively, and should connect and support propons 3 simultaneously herein.At the back axle correct position of road grader, a driving pump 9 that launched machine drags is installed, it is communicated with all CD-ROM drive motor 10 by pipeline and pipe fitting, provide pressure oil to them.The hydraulic-driven oil circuit be designed to complete machine be same closing oil path.What should emphasize at this is the control oil channel that drives oil circuit, should ensure the forward and backward bridge wheel synchronized operation of road grader.Technical matters has two technical solution schemes hereto.One if the back axle wheel is a Mechanical Driven, then extracts signal from the transmission of back axle wheel terminal, by the rotating speed of control setup control propons wheel 4.Its two, if the back axle wheel is a hydraulic-driven, then can adopt parallel way to get final product the driving oil circuit of forward and backward bridge wheel.
Embodiment 2: see also Fig. 1,3, A portion (being the leading section below of forebay) at the forebay 1 of road grader, increase one 0～6000 rev/min CD-ROM drive motor 12 is housed, drag drop-gear box 13 and rotate, its output shaft is connecting propons 14 (CD-ROM drive motor 12, drop-gear box 13 and propons 14 all fail to illustrate) in Fig. 1.This propons 14 is shaped on the shell that does not rotate, and its inner transmission device except that being provided with the input shaft that connects drop-gear box 13, also is provided with the two-way rotation output of stretching out directed in opposite on same direction of axis line.In the two-way rotation output of this propons 14, propons wheel 4 is installed respectively.Can certainly be not shown, but those skilled in the art can imagine out fully, be about to said drop-gear box and propons and make an integral body, can realize the driving of propons wheel equally.At the back axle correct position of road grader, the driving pump 11 that a launched machine drags is installed equally, it is communicated with CD-ROM drive motor 12 by pipeline and pipe fitting, provide pressure oil to it.
