滞留して牽引力増強とはならないのであり、またラグが
あまり高いと平地走行の時にラグが座屈して亀裂や折損
の原因となるのであり、このためラグの有効高さを維持
することにより牽引力を確保することが必要となされて
いる。(Prior Art) Conventionally, as a rubber crawler for wetlands, the rug height is relatively high because it is necessary to increase the traction force in the wetlands. However, if the rugs are simply high, mud will stay between the rugs. It does not increase the traction force, and if the lug is too high, it will buckle and cause cracks or breakage during flatland traveling.Therefore, maintain the effective height of the lug to secure the traction force. Is needed.

fとなさしめて、クローラ本体1の一側端は分岐ラグ3
b,3b……で山切り状に縁取りされた状態としてある。Reference numeral 3a denotes a long lug, which is provided at intervals of two sprocket claw engaging holes 2 so as to extend in the width direction of the crawler body 1, and the long lug 3a is moved toward the one edge of the crawler body 1 in the Y direction. The branch lugs 3b, 3b are formed at the V-shaped portion of the branched tip by branching into a letter shape, and the branch lugs 3b, 3b are formed as a thinned portion f, so that one end of the crawler body 1 is a branch lug 3
It is in a state of being trimmed into a mountain shape with b, 3b ....
3cは短ラグで上記長ラグ3aに挟まれた2個のスルロケ
ット爪係合孔2の間に同じ並列状態に設けしめてなる。3c is a short lug and is provided in the same parallel state between the two through rocket claw engaging holes 2 sandwiched by the long lugs 3a.
一方、mは分岐ラグ3b,3bの内方付け根部(長ラグ3a
と分岐ラグ3bとの分岐点)、nは外方側端部で、隣接す

置するようになっている。On the other hand, m is the inner root of the branch lugs 3b, 3b (long lug 3a
And a branching lug 3b), n is an outer end, and adjacent branching lugs 3b, 3b are formed so as to form a paddle of a constant width at this time. Is located on the same line as the short lug 3c.
他方4は上記分岐ラグ3b,3bの付け根部分mが位置す

In addition, 5 is a core metal and 6 is a steel cord.
上記実施例では長ラグ3aと短ラグ3cとを交互に並列さ
せて、短ラグ3cにより外方への泥捌けの容易さを考慮し
た構成であるが、短ラグ3cを省略することにより更に泥
捌けを容易に出来る。In the above embodiment, the long lugs 3a and the short lugs 3c are alternately arranged in parallel, and the short lugs 3c are used in consideration of the ease of removing mud to the outside. Easy to handle.
なお、第3図は別の実施例を示すものであって、分岐

の側端に於いても分岐ラグ3b及び欠肉部f′を設けたも
のである。Incidentally, FIG. 3 shows another embodiment, in which the branch lugs 3b are curved in a concave shape along the cutout portions f, and adjacent branch lugs are provided between the front and rear cutout portions f. 3b and 3b are connected at the outer end. FIG. 4 shows still another embodiment, in which a branch lug 3b and a cutout portion f'are provided at the other side end of the rubber crawler body 1 as well.
(考案の効果) 本考案によるゴムクローラは上記の如く構成するた
め、下記の如き優れた効果を奏するものである。(Effect of the Invention) Since the rubber crawler according to the present invention is configured as described above, it has the following excellent effects.
分岐したラグを構成し、該ラグ間に欠肉部fを設け
たため、該ラグが泥土中に十分潜入して検印力が増強さ
れる。Since the lugs are branched and the flesh part f is provided between the lugs, the lugs sufficiently infiltrate into the mud to enhance the stamping force.
欠肉部fは分岐ラグの付け根よりクローラ側端に向
けて巾広となしてあるため、欠肉部に侵入した泥土は円
滑に且つ確実に排出、脱落されるものとなり、牽引力の
低下がない。Since the thickness-reduced portion f is widened from the root of the branch lug toward the end on the crawler side, the mud that has entered the thickness-reduced portion can be discharged and dropped smoothly and reliably, and there is no reduction in traction force. .
クローラ周方向前後の欠肉部間に於いて隣接する分
岐ラグの付け根間隔が広く、且つ内周側には屈撓防止体
が形成されているため、該付け根付近では屈曲し難いも
のとなって、この部分に応力集中が殆ど生じないため、
亀裂、折損が生じないものとなって耐久性が改善され
る。Since the distance between the roots of the adjacent branch lugs is wide between the cutout portions before and after the crawler circumferential direction, and the anti-bending body is formed on the inner circumferential side, it is difficult to bend near the roots. , Since stress concentration hardly occurs in this part,
No cracking or breakage occurs and durability is improved.

側には泥土が排出されなくなり農作業を行う上で未収穫
の作物上に泥土が落とされることがなくなり作業効率が
良くなる。Since one edge of the rubber crawler body is edged by the branch lug, the mud that is below the rubber crawler and is compressed by the airframe load is prevented from moving by the branch lug and is not discharged to the branch lug side. Therefore, if the side provided with the branch lug is installed so as to be the outside of the machine body, the mud is not discharged to the outside and the mud is not dropped on unharvested crops during agricultural work, resulting in good work efficiency. Become.
