Problems solved by technology

[0002] In the prior art, the traveling wheel train of a crawler tractor will experience a lot of uneven and rugged areas, of course there will be a lot of vibration of the whole tractor and the swinging and deformation of the wheel train structure, etc. The track tensioning mechanism of a crawler tractor includes a driving wheel and a driven wheel. Tracks are sheathed on the outside of the driving wheel and the driven wheel. Several supporting wheels are evenly arranged between the driving wheel and the driven wheel. The sides are fixedly connected by two baffles, and there are several pairs of bolt holes symmetrically arranged at both ends of one side of the baffle. The wheel train structure provided by it cannot play a good damping effect and maintain the wheel train structure in rugged areas for a long time. Time is not easy to go bad

Embodiment 1

[0055] Example 1, such as figure 1 , 2 , 3, 4, and 5, a crawler wheel train of a tractor includes two wheel train units arranged opposite to each other, and each of the gear train units includes a tension wheel 81, a guide wheel 82, and a tension wheel 81 arranged front and rear. The driving wheel 83 above the guide wheel 82 and the crawler belt 84 wound on the tensioning wheel 81, the guide wheel 82 and the driving wheel 83, the tensioning wheel 81 and the guide wheel 82 are also arranged front and rear in sequence The first weight wheel 851, the balance wheel group 850 and the second support wheel 852, the track 84 is also wound around the first support wheel 851, the balance wheel group 850 and the second support wheel 852 On the lower side, the balance wheel set 850 has two pairs of front and rear balance wheels 8500 that can float up and down, and the height of the tension wheel 81 and the guide wheel 82 are higher than the height of the first support wheel 851 and Both ar...

Embodiment 2

[0065] Example 2, such as Image 6 As shown, a tractor chassis assembly, the chassis frame, the crawler train of the tractor described in embodiment 1 is installed on the chassis frame, and a gearbox is also installed on the chassis frame 400, engine 401, shock absorber 402, the shock absorber 402 has two and are respectively installed between the lower left side of the engine 401 and the upper left long beam 701 of the chassis frame and the lower left side of the engine 401 and the upper left side of the chassis frame Between the right long beam 702.

Embodiment 3

[0066] Example 3, such as Figure 7 , 8 9. As shown in 9, a crawler tractor chassis frame includes a lower frame 71 and an upper frame 72 fixed above the lower frame 71. The lower frame 71 is provided with two left and right sides above the rear side. There are two surrounding jackets 73 for the left and right side drive wheel shells of the gearbox to be sleeved respectively. The surrounding jacket 73 has a rotation space 730 for the drive wheel shells of the gearbox to rotate. The drive wheel housing is a circular protective housing outside the drive shaft of the gearbox for driving the tractor drive wheels. The sleeve connection between the surrounding jacket 73 and the drive wheel shells on the left and right sides of the gearbox should not be locked, and the drive wheel shells of the gearbox should be installed in the surrounding jacket 73 to rotate in the rotating space 730 In this way, when the tractor is vibrating, especially when the engine is vibrating, or when the eng...

Abstract

The invention relates to the technical field of tractors, in particular to a continuous track traveling wheel system of a tractor and a chassis assembly thereof. The continuous track traveling wheel system comprises two wheel system units symmetrically arranged on left and right sides, wherein each of the wheel system units comprises a tensioning wheel and a guiding wheel which are arranged on front and rear sides, a driving wheel positioned above the guiding wheel and a continuous track wound around the tensioning wheel, the guiding wheel and the driving wheel; a first supporting wheel, a balance swing wheel assembly and a second supporting wheel are sequentially arranged, from front to rear, between each tensioning wheel and the corresponding guiding wheel; the continuous tracks are alsowound around the lower parts of the first supporting wheels, the balance swing wheel assemblies and the second supporting wheels; each of the balance swing wheel assemblies is provided with two pairsof balance swing wheels, which are capable of floating up and down, on front and rear sides; and the tensioning wheels and the guiding wheels are higher than the first supporting wheels and the second supporting wheels so that the damping effect of the tractor is better.

Description

Technical field [0001] The invention relates to the technical field of tractors, in particular to a crawler walking wheel train and chassis assembly of a tractor. Background technique [0002] In the prior art, the walking wheel system of a crawler tractor will experience many uneven and rugged sections, and of course a lot of overall tractor vibration and swing and deformation of the wheel system structure will occur, such as the one disclosed in the publication number 107662660A The crawler belt tensioning mechanism of a crawler tractor includes a driving wheel and a driven wheel. The outer parts of the driving wheel and the driven wheel are covered with a crawler. A number of supporting wheels are evenly arranged between the driving wheel and the driven wheel. The two sides are respectively fixedly connected by two baffles. The two ends of the baffle are symmetrically provided with several pairs of bolt holes. The gear train structure provided by it cannot achieve a good vibra...
