れ、湿田での性能には効果を発揮している。 2. Description of the Related Art Conventionally, there are elastic crawlers used in traveling devices such as agricultural machinery, as shown in FIGS. 1 and 2. Fig. 1 shows a drive hole 2 and a core bar 3 in the widthwise central part of a belt body 1 formed in an endless shape from an elastic material.
and lugs 5 extending from the center in the width direction to the wing portion 4 side corresponding to each core metal 3.
Fig. 2 shows a short lug 6 located at the center in the width direction and a long lug 7 spanning the entire width.
and are provided alternately corresponding to each core metal 3. In these cases, when the pitch of the core metal 3 is P, the lag pitch at the center of the band body 1 is equal to the core metal pitch P, and in the wing part 4 it is twice the core metal pitch P, so that mud brushing is prevented. This has been improved and is proving effective in wet field performance.

る問題がある。 However, on the other hand, when traveling on a flat, hard road surface such as a concorito road surface, vibration of the aircraft body may become a problem, and this phenomenon is more common in smaller aircraft. Therefore, in order to alleviate such vibrations, as shown in FIGS. 3 and 4, a pair of left and right auxiliary lugs 8 are provided between the long and short lugs 6 and 7, or a pair of left and right auxiliary lugs is provided between the long and short lugs 7. 8 on both sides of the core bar 3 in the longitudinal direction of the band. However, in these cases, the lug pitch on the wing part 4 side is 2P, whereas the lug pitch at the center in the width direction is 1/2P or 2/3P, and therefore the space between the lugs at the center in the width direction is Because it is extremely narrow and the area of the narrow portion is large, there is a problem in that it is more likely to become clogged with mud.

According to the above configuration, the lug pitch on both sides of the drive hole 12 in the central portion of the band body 10 excluding the wing portion 11 is such that 2/3P and 4/3P are arranged alternately, and therefore, the lug pitch is such that 2/3P and 4/3P are arranged alternately. Since the pitch is the same as the core metal pitch P, it is possible to prevent mud clogging in the central part of the band body 10, and it is possible to maintain almost the same mud brushing performance as the conventional crawler shown in Figs. 1 and 2. . It can also suppress vibrations even when installed on small machines weighing less than 100 kg. That is, the wheels of the aircraft are often straddle wheels that roll in two rows symmetrically with respect to the drive hole 12, and in this case, one of these straddle wheels always has a lag pitch of 2/2. Since the 3P portion is rolled, a sufficient vibration damping effect can be obtained. The cross-sectional shape of the side lugs 15, 16 is such that the core metal 13 side is a gentle slope 15b, 16b,
The other side is steeply sloped 15c, 16c, and the bases 15c, 16c on the gentle slopes 15b, 16b are connected to the core metal 1.
3, it is possible to prevent the occurrence of cracks in the band body 10 due to the edges of the core metal 13. This applies to both forward and reverse directions. Also, since the extremely small auxiliary lug 8 etc. shown in Figures 3 and 4 are not used, the lug 1
Abrasion and damage of parts 4, 15, and 16 can be made uniform, and durability can be significantly improved by preventing cracks and the like and by preventing dirt from forming.

A gentle slope 16b'' may be provided. In this case, the base 16c may be extended to a position beyond the projection area of the core bar 13.

ジによる帯本体の亀裂等の発生を防止できる。 As detailed in the embodiments above, according to the present invention,
On the ground surface side of the band body, a center lug is arranged corresponding to every other core metal, and a pair of left and right side lugs are arranged in a staggered manner between each adjacent pair of center lugs. Since these lugs are arranged at equal pitches in the longitudinal direction of the strip, the average lug pitch in the center of the strip becomes equal to the pitch of the core metal, which maintains the same mud-brushing performance as before, and also improves rollability. The wheels always roll on the lug-corresponding parts, creating a sufficient vibration-proofing effect. Moreover, the top of the side lug is placed outside the projection area of the core metal, and
Since the slope of each side lug closer to the core metal is a gentler slope than the opposite side, and the base of this gentle slope is located within or beyond the projection area of the core metal, it is possible to prevent the occurrence of cracks in the band body due to the edge of the core metal. It can be prevented.
