因を招来する問題がある。 Conventionally, as a lug pattern of this kind of crawler belt, one in which a central lug overlapping the reinforced bone projection area and side lugs extending near both side edges of the endless belt-like body are provided is well known. By the way, the issues required of elastic crawlers are mainly good soil removal performance, securing of driving force, and durability due to sufficient rigidity of the lugs. However,
With the conventional lug shape, there is a problem in that when an improvement in driving force is taken into consideration, the soil removal performance is reduced, and when securing rigidity is improved, the driving force is reduced. In particular, the side lugs face the front edge of the strip, so they have relatively good earth removal performance, and can be freely shaped to take drive force and rigidity into consideration, but the above problem is serious for the center lugs. . For example, if the center lug is made wide in consideration of rigidity, it will not penetrate into the ground properly and the driving force cannot be increased. On the other hand, if the sprocket is formed into a substantially V shape in order to increase the traction force and secure the driving force, so-called soil clogging occurs, and as a result, no traction force can be expected. There is a problem in that blockage may cause derailment.
本発明は以上に鑑み、中央ラグの形状を改良し

出部分を形成して成る点にある。 In view of the above, the present invention improves the shape of the central lug, and satisfies all of the requirements for earth removal performance, driving force, and rigidity. That is, the present invention is characterized in that the entire body is formed into an endless band-like body made of an elastic material such as rubber, reinforcing bones are embedded in the central part of the band width direction at predetermined intervals in the longitudinal direction of the band, and the endless band-like body is In an elastic crawler track integrally formed with a central lug that overlaps with the reinforced bone projection area on the ground contact side: Both ends of the central lug located in the belt width direction expand forward in the crawler traveling direction at one end. While a protruding portion is formed, a protruding portion that protrudes rearward in the crawler track traveling direction is formed at the other end.

優れる。 According to the present invention, since the central lug has projecting portions at both ends, it has high rigidity and excellent durability. Moreover, since the center of the center lug can be made relatively narrow, it can bite into the ground well, and by forming the overhang, it is possible to form a bent edge, which satisfies the traction force and provides excellent driving force. Furthermore, the protruding portions at both ends are bulged in opposite directions, so that the front and rear edges of the center lug extend straight in one direction in the width direction without any obstruction, thereby providing excellent earth removal performance.

Counteract by carrying the resultant force. The engaging portion 6 is initially closed with a thin film during vulcanization, but by being broken by the engaging claw, the thin film is substantially attached to the protrusion 5A of the reinforcing bone 5. .

The wheel body, that is, the driving wheel, the idler wheel, and the intermediate idler wheel substantially support the body parts 8 on both sides, but the passing surface 7 may be formed by the top surfaces of a pair of left and right guide rails. This is desirable in that the central trunk extends deeply to better prevent the wheels from falling off.

Further, the pair of left and right side lugs 12 overlaps at least a portion of the projected area of the reinforcing bone 5 between the adjacent center lugs 11, and the pair of side lugs 12 are not arranged symmetrically, but are arranged in a longitudinal direction. They are unevenly distributed in a staggered manner.

The height of the side lugs 12 is increased to increase the traction force, and the space between the side lugs 12 is made flexible to improve earth removal performance.

の排土通路を経て良好な排土を約束する。 As a result of the present invention configured as described above, the central lug 11 has the projecting portions 11C at both ends, thereby ensuring a sufficient width, resulting in high rigidity and excellent durability. On the other hand, since the central portion 11D can be formed to be relatively narrow as described above, it can bite into the ground well, and in addition, both front and rear edges of the central lug 11 have a bent shape from the central portion 11D to the overhanging portion 11C. Since the crawler track is formed to have a shape of 1, it has excellent traction force both when the crawler track moves forward and when it moves backward. More particularly, in the present invention, the overhanging portions 11C at both ends are bulged in opposite directions, that is, one overhanging portion 11C bulges forward in the traveling direction, while the other overhanging portion 11C bulges backward in the traveling direction. Therefore, the soil removal performance is extremely excellent both when moving forward and when moving backward. Close the lid,
Both front and rear edges of the central lug 11 have an earth removal obstruction due to the overhanging portion 11C in one direction in the band width direction, but do not have any obstruction in the other direction, and there is no earth removal path in the other direction. We promise good soil removal through this process.
