【発明の詳細な説明】
この発明は1弾性無限軌道帯(以下り゛ローラという)
K関し、とくに湿田のごとき、車体重量による沈下が著

工夫を凝らした。この種クローラの改良を提案しようと
するものである。[Detailed Description of the Invention] This invention provides an elastic endless track belt (hereinafter referred to as a roller).
Regarding K, we have devised a way to make it easier to perform light turning operations, especially in applications where the vehicle is likely to sink significantly due to its weight, such as in wet fields. This paper attempts to propose improvements to this type of crawler.
一般にクローラは、長手方向に間隔をおいて埋め込み配
設した多数の横置芯金によって幅方向に補強したゴムま
たはゴム状弾性材料の弾性帯よりなシ、横置“芯金は9
弾性帯の輻一杯にわたるような長さではなく、#1%:
全幅の号程度で。In general, a crawler is made of an elastic band of rubber or rubber-like elastic material reinforced in the width direction by a number of horizontal core metals embedded at intervals in the longitudinal direction.
#1%, not the length that spans the full width of the elastic band:
About the size of the full width.
弾性帯の中央域を占めるのみではあるけれど4゜これに
よって弾性帯の耳縁附近Kかなりに高い横方向の剛性を
呈する上に1通常、り藁−ラの全幅にわたる接地ラグに
よって4強化される。Although it only occupies the central region of the elastic band, this results in a considerably higher lateral stiffness near the ear edge of the elastic band, which is usually reinforced by the grounding lugs that span the entire width of the straw. .
かような従来のクローラを装着した車両が。A vehicle equipped with such a conventional crawler.
ゆるい土質の湿田に入ったときに全体の沈下が深くなり
、そのため土中での旋回抵抗が増大し。When entering a wet field with loose soil, the overall settlement becomes deeper, which increases turning resistance in the soil.
また進行前面で堆積、***する盛土の反力がクローラの
は輩全幅にわたって作用するので推進抵抗本通大となり
、これらの抵抗により旋回運動が妨げられるとますます
沈下が迩むような悪循環が結果される不利があった。In addition, the reaction force of the embankment that accumulates and rises at the front of the crawler acts over the entire width of the crawler, resulting in a large propulsion resistance, and when turning movement is impeded by these resistances, a vicious cycle is created in which further subsidence occurs. There was a disadvantage.
この発明は、かような問題点を有利に克服すべく、湿田
の耕土中への沈下を効果的に防止するとともに、進行前
面にわだかまる盛土の±流れを良好に導くように配慮し
たものである。In order to advantageously overcome these problems, this invention is designed to effectively prevent the settling of wet fields into cultivated soil, and to better guide the flow of the embankment that is undulating in front of the field. .

方の耳部の内周面の外端縁が転輪通過面よりも内方に高
く形成されており。This invention is made of rubber or rubber-like elastic material, which is provided with a large number of horizontally placed core metals embedded at intervals in the longitudinal direction, and has lugs protruding from the outer surface on the grounding side in an arrangement corresponding to the horizontally placed core metals. The outer edge of the inner peripheral surface of at least one ear of the elastic band is formed higher inward than the wheel passing surface.

前記耳部のつけ根に変形抵抗の坐さい屈撓囲域を長手方

側に位置せしめるのがよく、前記の屈撓囲域は残内部が
2〜10mとなる深さで長手方向に沿う溝であるのが通
例である。t- The crawler is characterized in that the base of the ear has a deformation-resisting bending area in the longitudinal direction, and preferably the outer circumferential surface from the base of the ear to the outer edge gradually moves toward the inner circumference. The outer end edge of this inclined surface is preferably located at a horizontal position approximately between the wheel passing surface or on the inner circumferential side thereof, and the outer edge of this inclined surface is preferably located at a horizontal position approximately between the wheel passing surface and the inner circumferential side thereof. Usually, the groove is a longitudinal groove with a depth of 2 to 10 m inside.

さらには上記耳縁の変形自由度が大きいために、たと°
えスリップを生じようとしたとき+も。This bending area causes the outer edge of the vehicle body to curve when it attempts to sink due to the vehicle weight in wet fields,
Furthermore, the outer edge of the inner circumferential surface of the ear, which is the widthwise end of the crawler, is formed higher inward than the rolling wheel passing surface. 1 Normally, when turning, the rigidity of the stopped crawler The side edges do not have the tendency to be pushed into the adjacent lateral soil layer, but rather tend to climb up easily, which helps reduce turning resistance. In response to the propulsion reaction force, the contact area of the flexible ear edge deforms as if it were a rubber tire, easily guiding the flow to both sides and reducing embankment-like accumulation, reducing running resistance. Furthermore, since the degree of freedom of deformation of the ear rim is large,
Also when trying to cause a slip.
その原因のラグ間、泥土詰りかはく離し易いので、スリ
ップの軽減にも有利である。The cause of this is mud between the lugs, which is easy to peel off and is also advantageous in reducing slippage.
上記耳縁の屈撓囲域は、残肉厚2〜10mmとなる深さ
で長手方向に沿う溝により区分形成することが好ましい
が、これに限定されるものでないことは勿論である。It is preferable that the bending area of the ear rim is formed into sections by grooves along the longitudinal direction with a depth of 2 to 10 mm in remaining wall thickness, but it is needless to say that this is not limited to this.
この発明の適用はまた。屈撓囲域におけるラグ配列が一

。This invention also has applications. This is particularly advantageous when aiming to improve soil removal performance due to clogging between the lugs by arranging alternately every other lug in the bending area, and in this case, the horizontally placed core bar directly facing the bending area is It is desirable to have a thin rubber coating of at least 5W and no more than 1O2 on the outer end of the tube.
また、耳部における外周面は平置又は曲面をもって漸次

とんど生起せず従って牽引力のロスは僅少となるもので
ある。In addition, if the outer circumferential surface of the ear part is laid flat or is curved and gradually slopes inward, the center part of the crawler may sink to the hard soil layer inside the wet field when traveling through wet fields, etc., and the outer circumferential surface of the ear part Since the crawler moves while removing mud to the left and right on the inclined surface, mud hardly accumulates on the front surface of the crawler, and therefore the loss of traction force is minimal.

脱翰郷も防ぐことかで睡るようになったのである。In other words, in the present invention, the mud is distributed to the left and right without reducing the propulsion force, and the amount of mud deposited on the inner circumferential surface of the crawler that exceeds the periphery of the crawler is extremely reduced. This is because it prevents the ingestion and also prevents the death of the dead.

するものとする。6 shows the entire crawler equipped with the above-mentioned parts, and it is not much different from conventional crawlers of this type. In this invention, the crawler 6 connects the straight line connecting the outer ends of the horizontal mandrel 1 to the base of the ear A on at least one side (in the illustrated example, the ears on both sides) that is slightly apart outward than -t. In particular, it has a bending area 8 with low deformation resistance at the base (the root part).

However, when the vehicle enters a wet field and the weight of the vehicle causes the vehicle to make contact with the ground over the entire east end of the vehicle, the weight of the vehicle causes the vehicle to sink slightly.
屈撓囲域8においてクローラ6の耳ムが取残されるよう

にもたらされて、耳ムが、それに隣接する側方の泥土層
K[接向い合うことが妨げられて、むしろ該泥土層に乗
りか\るような姿勢を取゛ることとなる。The selvage of the crawler 6 is left behind in the bending area 8, and a bay in the cross section of the roller 6 is created along with the deformation of the selvage edge. They are prevented from facing each other, and instead take a posture as if they are standing on top of the mud layer.

向が強いため。Therefore, when the crawler 6 on one side is stopped and only the other side is driven when turning operation is required in the wet field, the ear of the crawler 6 on the stopped side is not buried in the corresponding mud layer. Above the mud layer Kl! ! lThere is a strong tendency to move up.

推進抵抗の軽減効果も著しい。There is no need to worry about turning resistance increasing, and on the other hand, as the mud piles up and accumulates in front of the drive side crawler 6Fi, the relative flow of the soil is guided along the curved edge of the ear. Rather, they play together while climbing on the accumulated mud, reducing propulsion resistance and allowing smooth turning motion to the container even in wet fields.Of course, the effect of reducing propulsion resistance when traveling straight is also remarkable. .

とができるわけである。As described above, it is advantageously avoided that the ears of the crawler sink into the mud of the wet field, so that the rigid ears, which conventionally easily sank into the mud, sink into the adjacent soil layer. In addition to bringing about a light turning movement without receiving the turning resistance that would result from being sunk in, the above-mentioned curvature also advantageously directs the relative flow between the mud and the mud in front of the vehicle to the side, thereby promoting the vehicle. This means that resistance can be effectively reduced.
