輪を防止したことを主目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to an improvement of an elastic crawler track which is formed entirely of an elastic material such as rubber in an endless shape, and in which two rows of reinforcing bodies in the belt width direction are arranged in rows in the belt longitudinal direction. When driving on uneven ground, or on roads with steps such as curbs, derailment is prevented by preventing bending at the boundary between two rows of reinforcing bodies in the width direction, that is, at the center of the belt body. The main purpose is

構成したものは既知である。 2. Description of the Related Art Elastic crawler tracks used in endless traveling devices are known, which are made entirely of rubber or other similar elastic materials.
この弾性履帯に、荷重支持の役目と、駆動用係
合爪の係合用等としてその帯長手方向に一定間隔
ごとに金属製補強体（芯金）が埋設されている。 Metal reinforcing bodies (core metals) are embedded in this elastic crawler belt at regular intervals in the longitudinal direction of the belt for the purpose of supporting the load and engaging the driving engaging pawl.
ところで、前記補強体を帯巾方向２列に埋設さ
れたクローラ用弾性履帯として本出願人は先に、
特公昭56−32146号公報で開示し、好評を受けて
いる。 By the way, the present applicant has previously developed an elastic crawler track for a crawler in which the reinforcing bodies are embedded in two rows in the width direction.
It was disclosed in Japanese Patent Publication No. 56-32146 and has been well received.
しかしながら、前記従来例にあつては、帯巾方

体の肉厚をできるだけ小さくすることから、履帯
中央部での屈折が、例えば、不整地又は縁石等の
ように段差のある路面走行のとき生じるおそれが
あつた。 However, in the conventional example, the rigidity of the boundary portions of the reinforcing bodies corresponding in the belt width direction, that is, the crawler center portion and both crawler side portions, is approximately equal in rigidity for the purpose of material saving, weight reduction, etc. Therefore, since the thickness of the belt-like main body is made as small as possible, there is a risk that bending at the center of the crawler track may occur, for example, when driving on uneven ground or on a road surface with a step such as a curb.
かかる履帯中央部での屈折現象は脱輪を招くこ
とから防止しなければならず、屈折と復元を繰返
し受けると、履帯中央部の疲れが早く、耐久性の
点でも不利である。 Such a bending phenomenon at the center of the crawler track must be prevented as it may lead to derailment, and if the track is repeatedly bent and restored, the center of the track will quickly fatigue, which is disadvantageous in terms of durability.
而して、前記屈折現象を防止するため、履帯全

軟弱地での走行性能が低下するばかりでなく、コ
スト高になる。 Therefore, in order to prevent the above-mentioned refraction phenomenon, if the thickness of the entire crawler track is increased and the rigidity of both the center and side parts is increased, the entire crawler track becomes extremely large and heavy, resulting in lower ground pressure. resulting in a decrease in
Not only does the running performance on soft ground deteriorate, but the cost also increases.
また、中央部、サイド部の剛性をともに大きく
すると、段差走行、不整地走行等にさいして荷重
の逃げ部分がなくなり、中央部での曲りが生じ充
分な効果を得られないことになる。 Furthermore, if the rigidity of both the center and side portions is increased, there will be no load escape area when driving over bumps, uneven terrain, etc., and the center portion will bend, making it impossible to obtain sufficient effects.

ていることを特徴とする。 Therefore, the present invention has been devised in order to solve the problems of the conventional example. Therefore, in the present invention, there is a wire in the band width direction 2 inside the band-shaped main body, which is made of an elastic material and is formed in an endless shape. In an elastic crawler track in which rows of reinforcing bodies are buried at intervals in the belt longitudinal direction and two rows of interlocking parts are formed between the reinforcing bodies in the belt longitudinal direction, the ends where two rows of reinforcing bodies in the belt width direction face each other. The wall thickness of the elastic material in the vicinity is thicker than the inner thickness of the elastic material in the vicinity of each outer end of the reinforcing body, and most of the thickening part is formed on the ground side. It is formed to be higher on the opposite inner surface side, and furthermore,
A horizontal reinforcing body is embedded in the thickened portion in a wrapping manner.
以下、図面を参照して本発明の実施例を詳述す
る。 Embodiments of the present invention will be described in detail below with reference to the drawings.
第１図、第２図は本発明の実施例であり、図に

る。 The belt-like main body 2 is formed entirely of an elastic material in an endless shape, and therein are metal reinforcing bodies 3, 4 having protrusions 3A, 4A in two rows in the band width direction in this embodiment.
are buried at intervals in the longitudinal direction of the band, and two rows of engaging portions 7 and 8 are formed between the reinforcing bodies 3 and 4 in the longitudinal direction of the band, with which engaging claws of a drive sprocket (not shown) engage. 7 and 8 are substantially open window structures.
伸長阻止体５，６は補強体３，４の埋設底部両
サイドにそれぞれ帯長手方向に埋設された無端状
である。 The elongation blockers 5 and 6 are endless and are embedded in the longitudinal direction of the belt on both sides of the buried bottoms of the reinforcing bodies 3 and 4, respectively.
９は弾性履帯の中央部、１０，１１は弾性履帯

側と反対の内面側に高くなるように形成されてい
るのである。 Reference numeral 9 indicates the center part of the elastic crawler belt, and 10 and 11 indicate both side parts of the elastic crawler track. It is designated as H1, and both side parts 10,
The thickness of the elastic material near the outer side of each of the reinforcing bodies 3 and 4 in 11 is denoted by H2, and H1>H2, so that a thickened part 12 is formed in the center due to the difference in thickness, Most of the thickened portion 12 is formed to be higher on the inner surface side opposite to the ground side.
即ち、増肉部１２の形成手段として、本実施例

長手方向全長にわたつて形成することができる。
これによれば、巻掛抵抗はやや増大するが、中央
部９の内面側に凹凸がなく平坦面となるため排土
性の点で又、土付着防止の点で有利となる。 That is, as a means for forming the thickened portions 12, in this embodiment, the thickened portions 12 are arranged at the same pitch as the longitudinal direction of the reinforcing bodies 3 and 4, as shown in FIG. The thickened portion 12 can be formed in the central portion 9 over the entire length in the longitudinal direction of the band.
According to this, although the winding resistance increases somewhat, the inner surface of the central portion 9 has no unevenness and becomes a flat surface, which is advantageous in terms of soil removal performance and prevention of soil adhesion.
更に、増肉部１２はこれをラグ１３が形成され

肉厚差（H1−H2）の部分だけは少なくとも低く
なることから、本発明の実施例では増肉部１２の
大部分を反接地面側に形成しているのである。 Furthermore, it is conceivable that the thickened portion 12 is formed on the side of the ground contact surface where the lugs 13 are formed, but according to this, the elongation of the surface on the ground contact surface side is becomes larger and causes cracks, and the height of the lug 13 is at least lower at the portion where the wall thickness difference (H1-H2) exists. is formed on the side opposite to the ground plane.
これによつて、弾性材料による補強効果は伸び
によるものより、圧縮によるものが数倍の補強効
果があることからも、増肉部１２を反接地面側に
形成する意義がある。 Thereby, since the reinforcing effect of the elastic material is several times stronger due to compression than that due to elongation, it is significant to form the thickened portion 12 on the side opposite to the contact surface.

１６を形成することが望しい。 Further, reference numeral 14 denotes a horizontal reinforcing body, which is made of a metal plate material, a bar material, a hard resin plate material, a bar material, etc. In order to increase the rigidity of the boundary between the reinforcing bodies 3 and 4 at the center of the crawler track, the thickened part 12 is used. It is buried in a wrapped shape. In this case, in order to ensure sufficient elasticity between the reinforcing body 14 and the wing portions 3B, 4B of the aforementioned reinforcing bodies 3, 4, and to ensure sufficient bonding force, the thickened portion 12 is A horizontal reinforcing body 14 is buried closer to the top side, and its surface is covered with an elastic membrane 15. In addition, as shown in FIG.
It is desirable to form the groove 16 so that there is no stress concentration between the grooves A and 4A.
又、横置補強体１４は増肉部分１２の全体又は
全部に設けることもできるが、第２図に示す如く
交互に設けることもできる。 Further, the horizontal reinforcing bodies 14 can be provided on the whole or all of the thickened portion 12, but they can also be provided alternately as shown in FIG.

ラ）を構成する。 Next, to explain the operation, the elastic crawler track 1 is endlessly wound around wheels such as a driving wheel, a driven wheel, and an idler wheel (not shown), and the engaging claws sequentially engage with the engaging parts 7 and 8. The endless traveling device (crawler) is configured by being circulated by the robot.

作用により、該中央部の弾性材料の亀裂に至るの
である。 Therefore, when traveling on a stepped road surface D as shown in FIG. 3, 1 and 2, in the conventional example, due to the body load acting on the wheels R, two rows of reinforcing bodies B and C as shown in FIG. In between, the elastic crawler track E is bent, the distance between the two rows of reinforcement protrusions becomes shorter, and a dimensional difference with the interval dimension A of the wheel body R occurs, and along with this dimensional difference, the inclination angle of the crawler track on the upper side of the step rises. As θ 1 increases, derailment occurs, and the repeated elongation and compression due to bending in the central portion leads to cracks in the elastic material in the central portion.
これに対し、本発明の実施例では履帯中央部に

小さくなつて脱輪が防止されるのである。 On the other hand, in the embodiment of the present invention, the thickened part 12 is formed at the center of the crawler track to provide sufficient reinforcement, so there is almost no bending of the crawler track 1 as shown in FIG. There is almost no dimensional difference between the protrusions 3A, 4A and the distance between the wheels, and the inclination angle θ is also small, thereby preventing wheels from coming off.
更に、増肉部１２には横置補強体１４がつつみ
込み状に埋設されているから、前記中央部での屈

４によつて撓みをなくし、しかも弾性部が増肉部
１２を介して補強体３，４間に形成されているこ
とから、亀裂も起ることないのである。 Furthermore, since the horizontal reinforcing body 14 is embedded in the thickened portion 12, bending at the central portion is completely prevented, and the horizontal reinforcing body 1
4 eliminates deflection, and since the elastic part is formed between the reinforcing bodies 3 and 4 via the thickened part 12, no cracks will occur.

ていることを特徴とするので、次の利点がある。 The present invention is as described above, and in short, in the present invention, two rows of reinforcing bodies 3 and 4 in the band width direction are embedded at intervals in the band longitudinal direction inside the band-shaped main body 2, which is formed in an endless shape entirely from an elastic material. , in an elastic crawler track 1 in which two rows of engagement parts 7 and 8 are formed between reinforcing bodies 3 and 4 in the belt longitudinal direction, two rows of reinforcing bodies 3 in the belt width direction,
A thickened portion 12 is formed in which the thickness of the elastic material near the opposite ends of the reinforcing bodies 3 and 4 is thicker than the thickness of the elastic material near the outer ends of each of the reinforcing bodies 3 and 4,
Most of the thickened portion 12 is formed to be higher on the inner surface side opposite to the ground contact side, and furthermore, a horizontal reinforcing body 14 is embedded in the thickened portion 12 in a wrapping manner. Therefore, there are the following advantages.
補強体３，４が向い合う端部附近の弾性材料肉

材料肉厚よりも厚肉とされた増肉部１２が形成さ
れているので、履帯１が段差路面を走行しても、
中央部からの屈折が抑えられ、脱輪が防止でき
る。 A thickened portion 12 is formed in which the thickness of the elastic material near the opposing ends of the reinforcing bodies 3 and 4 is thicker than the thickness of the elastic material near the outer ends of each of the reinforcing bodies 3 and 4. Therefore, even if crawler track 1 runs on a stepped road surface,
Refraction from the center is suppressed, preventing the wheels from falling off.
しかも、増肉部１２は所謂履帯１の中央部に形

きる。 Moreover, the thickened part 12 is only formed in the so-called central part of the crawler track 1, and the thickness is not increased even on both sides of the crawler track 1, which may result in excessive weight or a decrease in ground contact pressure. It is also possible to effectively release the load when driving on bumps or uneven terrain.
更に、増肉部１２は反接地側に形成されている
ので、接地面側の土蹴り出し力はそこなわれるこ
となく、牽引力の低下を招くことはなく、履帯１
中央部の剛性を大きくできる。 Furthermore, since the thickened portion 12 is formed on the side opposite to the ground, the soil kicking force on the ground side is not impaired and the traction force is not reduced, and the crawler 1
The rigidity of the central part can be increased.
更に、増肉部１２には横置補強体１４がつつみ

も、増肉部１２に亀裂が起ることがない。 Furthermore, since the horizontal reinforcing body 14 is embedded in the thickened part 12, the rigidity of the central part of the crawler track is completely guaranteed, bending and deflection from the central part are small, and even when the crawler is placed horizontally, Even if the reinforcing body 14 is buried, cracks will not occur in the thickened portion 12.
