Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, the present invention includes: crawler belt 1 and for the hydraulic support frame 3 that supports crawler belt and the first support wheel 7, second support wheel 8, the 3rd support wheel 9, the first described support wheel 7, second support wheel 8, the 3rd support wheel 9 are rotating corner gear.
Hydraulic support frame 3 comprises support hydraulic pressure cylinder body and is arranged on three hydraulic stems on support hydraulic pressure cylinder body, the end of hydraulic stem is all equipped with the circular arc gear piece 2 engaged with the internal tooth of crawler belt 1, circular arc gear piece 2 and the first support wheel 7, second support wheel 8, 3rd support wheel 9 all engages with crawler belt, and form a circle, rod hinge connection is passed through in the middle of first support wheel 7 and the second support wheel 8 and the first support wheel 7 and the 3rd support wheel 9, as shown in Figure 6, be connected by expansion link between second support wheel 8 with the 3rd support wheel 9, spring 6 is also fixed with between second support wheel 8 and the 3rd support wheel 9, spring 6 is placed on outside expansion link.Crawler belt 1 is rubber belt track.
The medial center of described support hydraulic pressure cylinder body is provided with one and caves in cone tooth 16;
First gear 11 and the second gear 10 are in transmission connection by chain 14;
Second gear 10 is connected by hydraulic pressure oil transportation hollow shaft 13 with the support hydraulic pressure cylinder body of hydraulic support frame 3, be revolute pair connection mode between the support hydraulic pressure cylinder body of hydraulic support frame 3 and hydraulic pressure oil transportation hollow shaft 13, there is rubber seal inside, prevents the leakage of hydraulic oil.
Transaxle 4 is placed on hydraulic pressure oil transportation hollow shaft 13, and transaxle 4 can be moved by hydraulically extensible; The center of the second gear 10 also has one and to cave in cone tooth; As shown in Figure 4, one end of transaxle 4 has can bore the intermeshing two-sided cone tooth of tooth 16 with the second gear 10 and caving in of support hydraulic pressure cylinder body, and corner gear 7 is connected with the first gear 11 by transmission shaft 12;
The outside of the outer actuating device be made up of the first gear 11, second gear 10 and chain 14 is also provided with position-limited lever 15, makes outer actuating device position be fixed and can not produce skew.
Due to the first support wheel 7, second support wheel 8, the 3rd support wheel 9, circular arc gear piece 2 common support of three hydraulic stems crawler belt 1, crawler belt 1 is in tensioned state, due to the effect of power, spring 6 also fixing between second support wheel 8 and the 3rd support wheel 9 is in compressive state, now, crawler belt 1 is in a circular state substantially.Transaxle 4 is connected with driving engine, it is the sole power source of whole wheel movement, the conversion regime realizing motion is, control to make motion transaxle 4 axially realize moving by control system, when motion transaxle 4 leans against on hydraulic support frame 3, the caving in of the finishing bevel gear cuter of motion transaxle 4 and support hydraulic pressure cylinder body is bored tooth 16 and is engaged, and drives hydraulic support frame 3 to rotate, thus the structure twirl of whole wheel one circle.
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 contacts with crawler belt and engages, crawler belt is in lax shape, spring 6 Rapid reset fixing between second support wheel 8 and the 3rd support wheel 9, the distance between the second support wheel 8 and the 3rd support wheel 9 is made to become large, first support wheel 7, second support wheel 8, the 3rd support wheel 9 present an isosceles obtuse-angled triangle, as shown in Figure 5, the wheel of whole crawler belt parcel is in an isosceles obtuse-angled triangle, and the wheel area that lands is large.Promote transaxle 4 by Hynautio-steering to move to the direction of the second gear 10, transaxle 4 is no longer connected with hydraulic support frame 3, hydraulic support frame 3 is in passive delivery state, the bore at the middle pit of the stomach of the second gear 10 is a bit larger tham the diameter of transaxle 4, make the axis body of transaxle 4 can pass the middle pit of the stomach of the second gear 10, like this, the cone tooth of transaxle 4 end can be bored tooth and engages with being caved in of the second gear 10, the second gear 10 is driven by transaxle 4, by chain 14 with transmission first gear 11 is rotated, and the first gear 11 has the rotation being driven the first support wheel 7 by transmission shaft 12, thus realize the rotation of crawler belt 1.
