At the same time, the tracks have the characteristics of low ground contact pressure and good soil protection performance. Compared with traditional metal tracks, rubber tracks cause less damage to the road surface when driving on the road. However, compared with tires, rubber tracks have disadvantages such as large vibration and large road rolling resistance when driving on the road. Utility Model Content
[0003] In order to solve the above technical problems, one of the purposes of the present invention is to provide a rubber crawler with a simple structure, low vibration when traveling on the road, and good passability when working in the field.

[0009] The beneficial effects of the above technical solution are: its structure is simple, and the contact area between the central ridge and the ground is smaller than the contact area between the main ridge and the ground, so that the contact area between the track and the road is small when it is running on the road, and it can have a larger friction coefficient with the ground when it is running in the field.
[0010] The main convex patterns on both sides of the crawler body in the above technical solution are distributed in a staggered manner.
[0011] The beneficial effect of the above technical solution is that it makes the rubber track more passable during field operations.
[0012] In the above technical solution, the main ridges are arranged obliquely in the width direction of the crawler body.
[0013] The beneficial effect of the above technical solution is that the passability of the rubber track during field operations is further improved.

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0032] Example 1
[0033] like Figure 1-Figure 3 As shown, this embodiment provides a rubber track comprising a track body 1 made of rubber. The outer surface of the track body 1 is provided with a plurality of main ridges 3 and a plurality of central ridges 2. The depth of the central ridges 2 is greater than the depth of the main ridges 3. By providing the central ridges on the track body and having a depth greater than the depth of the main ridges, when the track is traveling on a road, the central ridges contact the road surface, reducing the contact area between the entire track and the ground, resulting in low friction resistance and vibration. When traveling in a field, both the central ridges and the main ridges are embedded in the soil, making it less slippery and improving roadability. The depth of the central ridges (referring to the distance from the end of the central ridge to the track body) is L1, and the depth of the main ridges (referring to the distance from the end of the main ridge to the track body) is L2, i.e., L1>L2.
[0034] in, Figure 1The front-to-back direction is the length direction of the crawler body, and the left-to-right direction is the width direction of the crawler body.
[0035] In the above technical solution, a plurality of central ridges 2 are circumferentially spaced apart in the middle of the outer surface of the track body 1, and a plurality of main ridges 3 are circumferentially spaced apart on both sides of the outer surface of the track body 1. By arranging the main ridges on both sides of the outer surface of the track body and the central ridges in the middle of the width direction of the track body, when the track is traveling on the road, the plurality of central ridges are linearly distributed in the circumferential direction of the track, thereby mainly supporting the track and reducing vibration when traveling on the road. The plurality of central ridges are evenly spaced circumferentially on the track body, and the plurality of main ridges on the same side are also evenly spaced circumferentially on the track body.
[0036] In the above technical solution, the main ridges 3 are strip-shaped, and the central ridges 2 are columnar. They have a simple structure, and the contact area between the central ridges and the ground is smaller than the contact area between the main ridges and the ground. This makes the contact area between the track and the road small when driving on the road, and has a larger friction coefficient with the ground when driving in the field.
[0037] The main ridges 3 on both sides of the crawler body 1 in the above technical solution are staggeredly distributed, so that the rubber crawler has better passability during field operations.
[0038] In the above technical solution, the main ridges 3 are arranged obliquely in the width direction of the track body 1, so that the passability of the rubber track during field operations is further improved.
[0039] In the above technical solution, the two adjacent main ridges 3 in the width direction of the track body 1 are distributed in an "eight" shape, which further improves the passability of the rubber track during field operations.
[0040] In the above technical solution, the distance between two adjacent main ridges 3 on the same side is greater than the distance between two adjacent central ridges 2, so that when the rubber track is running on the road, the multiple central ridges have a better lifting effect on the entire machine.
