One end of transaxle has can be intermeshing two-sided with the cone tooth that caves in of second gear and support hydraulic pressure cylinder body
Cone tooth, the first support wheel is connected with first gear by power transmission shaft.
Further improvement, the outside of the outer driving means being made up of first gear, second gear and chain is also equipped with
Gag lever post.
Further improvement, is to rotate pair to be connected between the support hydraulic pressure cylinder body of hydraulic support frame and hydraulic pressure oil transportation hollow axle
Mode, there is rubber seal inside.
Further improvement, crawler belt is rubber belt track.
The invention has the beneficial effects as follows:Described hydraulic support frame includes support hydraulic pressure cylinder body and is arranged on supporting cylinder
Three hydraulic stems composition on body, the end of hydraulic stem is all equipped with circular arc gear piece engage with the internal tooth of crawler belt, circular arc gear piece and
Three corner gears are engaged with crawler belt, and form a circle, and this circular crawler track wheel construction advantage is that travel speed is fast, is suitable for dry
Dry road traveling, when by shrinking hydraulic support frame, the second support wheel and the 3rd support wheel are due to spring reset stretching, extension simultaneously
, so that road wheel becomes an obtuse triangle shape, the area that contacts to earth of the structure of this crawler belt is big, is suitable for for the distance between support wheel
Travel in more muddy place.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the present invention includes:Crawler belt 1 and for supporting the hydraulic support frame 3 of crawler belt and first
Support wheel 7, the second support wheel 8, the 3rd support wheel 9, described the first support wheel 7, the second support wheel 8, the 3rd support wheel 9 is can
The corner gear rotating.
Hydraulic support frame 3 includes support hydraulic pressure cylinder body and three hydraulic stems being arranged on support hydraulic pressure cylinder body, hydraulic stem
End be all equipped with the circular arc gear piece 2 engaging with the internal tooth of crawler belt 1, circular arc gear piece 2 and the first support wheel 7, the second support wheel
8th, the 3rd support wheel 9 is all engaged with crawler belt, and forms a circle, the first support wheel 7 and the second support wheel 8 and the first support wheel
7 and the 3rd support wheel 9 in the middle of pass through rod hinge connection, as shown in fig. 6, passing through between the second support wheel 8 and the 3rd support wheel 9 to stretch
Contracting bar connects, and is further fixed on spring 6, spring 6 is placed on outside expansion link between the second support wheel 8 and the 3rd support wheel 9.Carry out
Band 1 is rubber belt track.
The medial center of described support hydraulic pressure cylinder body be provided with one cave in cone tooth 16;
First gear 11 is in transmission connection by chain 14 with second gear 10;
Second gear 10 is connected by hydraulic pressure oil transportation hollow axle 13 with the support hydraulic pressure cylinder body of hydraulic support frame 3, and hydraulic pressure props up
It is to rotate secondary connected mode between the support hydraulic pressure cylinder body of support 3 and hydraulic pressure oil transportation hollow axle 13, there is rubber seal inside, prevents
The only leakage of hydraulic oil.
Transaxle 4 is placed on hydraulic pressure oil transportation hollow axle 13 so that transaxle 4 being capable of hydraulically extensible motion;Second gear 10
Center also have one and cave in cone tooth;As shown in figure 4, have can be with second gear 10 and support hydraulic pressure for one end of transaxle 4
The cone intermeshing two-sided cone tooth of tooth 16 that caves in of cylinder body, the first support wheel 7 is connected with first gear 11 by power transmission shaft 12;
The outside of the outer driving means being made up of first gear 11, second gear 10 and chain 14 is also equipped with gag lever post
15 so that outer driving means position is fixed and will not produce skew.
Due to the first support wheel 7, the second support wheel 8, the 3rd support wheel 9, the circular arc gear piece 2 of three hydraulic stems props up jointly
Support crawler belt 1, crawler belt 1 is in tensioned state, due to the effect of power, also fixing between the second support wheel 8 and the 3rd support wheel 9
Spring 6 be in compressive state, now, crawler belt 1 is generally in a circular state.Transaxle 4 is to be connected with electromotor
, it is the sole power source of whole wheel movement, the conversion regime realizing motion is that being controlled by control system makes motion change
Axle 4 is axially being realized moving, when motion transaxle 4 leans against on hydraulic support frame 3, the bevel gear of motion transaxle 4 and support
The cone tooth 16 that caves in of hydraulic cylinder engages, and drives hydraulic support frame 3 to rotate, thus the structure of whole wheel one circle quickly turns
Dynamic.
By shrinking three hydraulic stems on support hydraulic pressure cylinder body, the circular arc gear piece 2 of the end of hydraulic stem no longer with crawler belt
Contact engagement, crawler belt is in lax shape, and between the second support wheel 8 and the 3rd support wheel 9, fixing spring 6 Rapid reset, makes
The second support wheel 8 and the 3rd support wheel 9 the distance between become greatly, the first support wheel 7, the second support wheel 8, the 3rd support wheel
9 assume an isosceles obtuse triangle, as shown in figure 5, the wheel of whole crawler belt parcel is in an isosceles obtuse triangle, car
Take turns the area that lands big.By Hynautio-steering promote direction from transaxle 4 to second gear 10 move, transaxle 4 no longer with
Hydraulic support frame 3 connects, and hydraulic support frame 3 is in passive delivery state, and the bore of the center port of second gear 10 is slightly larger than and turns
Change the diameter of axle 4 so that the axis body of transaxle 4 can pass through the center port of second gear 10, so, the cone of transaxle 4 end
Tooth can with second gear 10 cave in cone tooth engage, by transaxle 4 drive second gear 10, by chain 14 with make transmission
First gear 11 rotates, and first gear 11 has the rotation driving the first support wheel 7 by power transmission shaft 12, thus realizing crawler belt 1
Rotation.
