As a conventional endless track belt, one shown in FIG. 1 is known. The entire endless band 100 is made of an elastic material such as rubber, and the endless band 100 is made of an elastic material such as rubber.
Core metals 101 are embedded in the widthwise central part of 00 and at predetermined intervals in the longitudinal direction, and engagement holes 102 that mesh with a drive sprocket (not shown) are formed between the core metals 101.
A lug 103 is provided on the outer peripheral surface of the endless belt 100 to dig into the soil and obtain driving force in wet fields, etc.
01. This rug 1
When installing the lug 103, it is known that if the distance between the lugs 103 is shortened, muddy soil will dig in between the lugs when driving in wet fields, muddy areas, etc., reducing the running performance. rug 10
Consideration has been taken to lengthen the distance from 3 to some extent. However, if the distance between the lugs 103 is made longer, the distance between the core metal 101 and the core metal 103 will inevitably increase.
This was a problem because the distance between the two ends of the endless belt 100 became longer and vibration or noise was generated when the wheels moved from the part of the endless band 100 made only of elastic material to the part where the core metal 101 was buried. In other words, there was a desire for a structure that suppresses vibrations, noise, etc. without sacrificing driving performance.

泥地での推進力が劣る。 As another conventional example, the one described in Japanese Utility Model Publication No. 17257/1983 is known. This is made of a rubber material, and meshing holes that mesh with the drive sprocket are bored at regular intervals in the rotational direction of the central part, and a core metal is buried between the meshing holes at predetermined intervals over an endless band on the left and right. A main grounding lug is formed on the outer circumferential surface of the main grounding lug directly below the core metal over substantially the entire width of the endless band. In addition, between the front and rear main grounding lugs, there is provided an auxiliary lug that is short enough to form a wider space in the left and right endless band between the front and rear main grounding lugs than the main grounding lug in the left and right direction from the vicinity of the engagement hole in the center of the endless band. There is. With this configuration, vibration and noise are prevented. In this conventional example, the auxiliary lugs are shorter than the main grounding lug in the center, shorter than the main grounding lug in the center, and left and right in the gap between the engagement holes in the rotational direction. It is simply a pair of short pieces that are arranged parallel to each other and symmetrically, which prevents the rubber from cracking in relation to the buried core metal, and further prevents noise and vibration. It has not been determined. The auxiliary lugs overlap most of the projected area of the core metal, and vibrations are likely to occur when the vehicle is normally driven on a road surface. In addition, the auxiliary lugs tend to become clogged with mud, etc. between the auxiliary lugs. Furthermore, this auxiliary lug is elongated in the direction of rotation, resulting in poor propulsion on muddy ground.

In this second embodiment, the auxiliary lug 8 of the first embodiment is configured to be shorter, and further consideration is given to the mud that gets stuck between the lugs, and the other configurations are the same as the first embodiment. A reference numeral is given and the explanation is omitted. The auxiliary lugs 8 formed corresponding to the edges of every other core bar 4 are not formed over the entire width of the endless band 1, but are formed to be slightly longer than the core bar 4, and furthermore, the lugs 8 are formed to correspond to the edges of every other core bar 4. 2 by hole 5
It is divided. This means that the main lugs 7 and 7 are separated by a large distance, and the mud adhering thereto can be easily removed, resulting in a structure that can generate propulsive force extremely effectively. In this manner, the second embodiment has a structure that not only suppresses the generation of vibrations, but also proactively takes into consideration the possibility of mud digging into the structure.

Other embodiments are shown in FIGS. 6 to 11. (In the following figures, both the main lug and the auxiliary lug are shown with the lug top surface.) First, what is shown in FIG. 6 is the engagement hole 5 of the auxiliary lug 8 in the second embodiment.
The parts divided by the above are integrated.
In what is shown in FIG. 7, the auxiliary lugs 8 in the second embodiment are replaced by a set of two auxiliary lugs 8 located diagonally on the core metal 4. Figure 8 shows the 6th
The auxiliary lug 8 shown in the figure is extended toward the end of the endless band 1. The one shown in FIGS. 9 and 10 has an auxiliary lug 8 covering the corner of the core bar 4, and the one shown in FIG. 11 has the main lug 7 also modified.

る。 Furthermore, from the viewpoint of running performance, it is also meaningful to make changes as shown in FIG. FIG. 12 is a diagram corresponding to FIG. 3, in which the wing portions 3, 3 extending on both sides of the central portion 2 of the main body are configured to be higher toward the inner circumferential surface, that is, to have a larger distance from the ground. This is what I did. With such a configuration, since both wing parts 3, 3 are flexible, they are easy to curve upward, and when driving in wet fields, the lugs at the bottom of both wing parts 3, 3 are in the mud, similar to the oars of a boat. With this function, it is possible to scrape muddy soil and significantly improve driving performance, thereby enhancing the effects of this embodiment.

As explained above, the present invention is made of an elastic material such as rubber, and has meshing holes in the center of the main body that mesh with the drive sprocket at predetermined intervals along the longitudinal direction, and a core metal between the meshing holes. An endless band in which is embedded a main body and provided with both wing parts extending outward from both sides of the central part of the main body, and main lugs and auxiliary lugs provided alternately on the outer circumferential side of the endless band in correspondence with the core bar. , the main lugs are formed over the entire width of the endless band in the width direction, and the auxiliary lugs provided between the main lugs are divided into at least two parts in the longitudinal direction of the endless band, and are formed on the projection plane of every other core metal. It is characterized in that it is arranged so as to cover the longitudinal ends of the core bar. Therefore, compared to the conventional example shown in FIG. Since this is repeated, the distance between the lugs becomes shorter, making it possible to suppress vibrations, noise, etc. that occur when driving on normal roads, and maintain driving performance on wet fields, muddy fields, etc. as before. Furthermore, since the main lugs are formed over the entire width, the driving force or propulsive force during running is not reduced, and the auxiliary lugs can prevent mud from getting between the lugs. In particular, in the case where the auxiliary lug is divided into front and rear parts of the core metal, the rolling wheels can be considered to be almost always on one of the lugs. It is possible to prevent shocks and noises that occur when moving from one place to another. Furthermore, since the auxiliary lug covers the edge of the core metal, it is possible to increase the thickness near the edge of the core metal, where rubber etc. are prone to cracking, thereby extending the life of the endless band.
