Technical Field
[0001] The utility model belongs to the technical field of rubber crawlers, and particularly relates to a noise-reducing and abnormal-sound-eliminating crawler. Background Art
[0002] Rubber tracks are annular belt-shaped products made of a composite of rubber and metal. This product has a wide range of uses and is widely used in many fields. During the use of rubber tracks, noise or abnormal sounds are prone to occur, which affects the driving effect and also affects the environment. Therefore, it is necessary to adopt appropriate methods to improve the use effect of the tracks to overcome the shortcomings of the tracks. Therefore, appropriate methods are proposed to reduce noise and abnormal sounds to better play the role of rubber tracks. Utility Model Content
[0003] The purpose of the utility model is to provide a noise-reducing and abnormal-sound-eliminating crawler track with a reasonable crawler structure setting to improve the noise-reducing and abnormal-sound-eliminating effect of the crawler track.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows.
[0005] A noise-reducing and abnormal-sound-eliminating crawler track comprises a crawler body, a driving wheel concave surface is provided in the middle position of the crawler body, a plurality of first crawler tooth columns and second crawler tooth columns are evenly arranged on both sides of the upper portion of the driving wheel concave surface, and a plurality of first pattern structure blocks and second pattern structure blocks are provided on both sides of the back side of the lower portion of the driving wheel concave surface; the first pattern structure blocks and the second pattern structure blocks are both strip pattern structure blocks, and a boss is provided at the middle concave surface of the first pattern structure blocks and the second pattern structure blocks.
[0006] Furthermore, a plurality of driving wheel holes are distributed on the concave surface of the driving wheel, and the driving wheel holes are inclined cross-shaped through grooves.
[0007] Furthermore, the transverse center lines of the patterns on the first pattern structure block and the second pattern structure block are offset, with the offset distance being 1-2 mm.
[0008] Furthermore, the concave surfaces on the first pattern structure block and the second pattern structure block are arranged opposite to each other, and the bosses are all distributed in the middle position of the concave surfaces.
[0009] Furthermore, the first track tooth column and the second track tooth column are arranged opposite to each other, with their center lines at the same height, and the first track tooth column and the second track tooth column are both arranged in an alternating manner with the drive wheel hole.
[0010] Furthermore, the height of the first track tooth column and the second track tooth column is 1.5 times the height of the first pattern structure block and the second pattern structure block.
[0011] Furthermore, the outer sides of the first pattern structure block and the second pattern structure block extend to the edge of the track body, and the inner sides extend to the concave edge of the driving wheel.
[0012] Furthermore, the bottom of the side surfaces of the first track tooth column and the second track tooth column are inclined upward at an angle of 1.5-2.5°.
[0013] Furthermore, the bottom of the side surfaces of the first pattern structure block and the second pattern structure block are inclined upward at an angle of 1.5-2.5°.
[0014] The beneficial effects of the utility model are as follows: in the utility model, the original block pattern structure of the rubber track is changed to a strip pattern structure, and the upper and lower patterns are not on the same center line. The purpose is to reduce the ground contact area of the track, and to make the pattern run continuously but not land at the same time. When the track is running, it does not affect the continuity of its use, but due to the reduction in its ground contact area, its noise generation is reduced. At the same time, a small boss is added in the middle of the upper and lower patterns to form a vortex structure. When the track is running, this structure can disperse the formation of sound waves and effectively remove abnormal sounds and noise. In addition, the utility model product uses a special rubber formula to reduce the hardness of the track pattern rubber, so that it has a soft transition with the ground and reduces the generation of noise. Compared with similar products, the structural characteristics are unique and the targeted functions are obviously effective. Maintenance costs are reduced, user costs are reduced; product quality is improved, and product service life is extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings to facilitate a better understanding of the present invention.
[0023] like Figures 1 to 6 The noise-reducing and noise-reducing crawler shown in the figure includes a crawler body 1 with a drive wheel concave surface 5 disposed in the middle. Multiple first and second crawler tooth posts 2 and 6 are evenly spaced on either side of the upper portion of the drive wheel concave surface 5. Multiple first and second tread blocks 3 and 7 are disposed on either side of the lower, back surface of the drive wheel concave surface 5. Each of the first and second tread blocks 3 and 7 is striped, with a boss located in the middle of the concave surface. Multiple drive wheel holes 4 are distributed on the drive wheel concave surface 5, with an inclined cross-shaped through-slot located in the middle. The tread patterns of the first and second tread blocks 3 and 7 are offset by 1-2 mm. This arrangement reduces the track's contact area and allows the tread pattern to operate continuously without simultaneously touching the ground. While the track's operation remains unaffected, the reduced contact area reduces noise generation.
[0024] The concave surfaces of the first and second tread blocks 3 and 7 are arranged opposite each other, with the bosses located in the middle of the concave surfaces. The additional bosses form a vortex structure. When the track is running, this structure can disperse the formation of sound waves and effectively eliminate abnormal sounds and noise.
[0025] The first track tooth column 2 and the second track tooth column 6 are arranged opposite each other, with their center lines at the same height. The first track tooth column 2 and the second track tooth column 6 are staggered with the drive wheel hole 4. The height of the first track tooth column 2 and the second track tooth column 6 is 1.5 times the height of the first pattern structure block 3 and the second pattern structure block 7. The outer sides of the first pattern structure block 3 and the second pattern structure block 7 extend to the edge of the track body 1, and the inner sides extend to the edge of the drive wheel concave surface 5. The bottom of the side of the first track tooth column 2 and the second track tooth column 6 are tilted upward at an angle of 1.5-2.5 degrees. The bottom of the side of the first pattern structure block 3 and the second pattern structure block 7 are tilted upward at an angle of 1.5-2.5 degrees.
[0026] This utility model is aimed at the rubber tracks used on specific machine models, which produce excessive noise and abnormal sounds during use. The structure of the track is improved by changing the original block pattern structure of the rubber track to a strip pattern structure, and making the upper and lower patterns not fall on the same center line. This reduces the ground contact area of the track, and allows the pattern to run continuously but not land at the same time. When the track is running, it does not affect the continuity of its use, but its noise generation is reduced due to the reduction in its ground contact area. At the same time, a small boss is added in the middle of the upper and lower patterns to form a vortex structure. When the track is running, this structure can disperse the formation of sound waves and effectively eliminate abnormal sounds and noise. Considering the impact of the rubber material on noise and abnormal sounds, a special rubber material formula is used to reduce the hardness of the track pattern rubber, so that it has a soft transition with the ground and reduces the generation of noise.
[0027] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
