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に生じるおそれ
があつた。 However, in the conventional example, the rigidity of the boundary portions of the corresponding reinforcing bodies in the band width direction, that is, the crawler center portion and both side portions of the crawler, is approximately equal, which contributes to material saving, weight reduction, etc. For this purpose, the wall thickness of the belt-like body is made as small as possible, so 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

もに大きくすると、履帯全体が非常に大形となり
重量過大となつて、接地圧の低下をきたし、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 track becomes extremely large and overweight, which reduces the ground pressure. This not only causes a decline in running performance on soft ground, but also increases costs.
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。 In addition, if the rigidity of both the center and side parts is increased, there will be no part for the load to escape when driving on bumps or rough terrain, and bending will occur in the center.
You will not be able to obtain sufficient effects.
そこで、本発明は、前記従来例の問題点を解消

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 embedded at intervals in the longitudinal direction of the band, and two rows of interlocking parts are formed between the reinforcing bodies in the longitudinal direction of the band,
The thickness of the elastic material near the opposing ends of the two rows of reinforcing bodies in the width direction is formed in a thickened part that is thicker than the wall thickness of the elastic material near the outer ends of each of the reinforcing bodies. Most of the thickened portion is formed to be higher on the inner surface side opposite to the ground side.
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
おいて、１は弾性履帯で、帯状本体２、補強体
３，４、伸長阻止体５，６等からなる。 1 and 2 show embodiments of the present invention. In the figures, reference numeral 1 denotes an elastic crawler track, which is composed of a belt-like main body 2, reinforcing bodies 3, 4, expansion prevention bodies 5, 6, and the like.

る。 The band-shaped main body 2 is formed entirely of an elastic material in an endless shape, and therein are metal reinforcing bodies 3, 4 having two rows of protrusions 3A, 4A 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 the engaging claws of the 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

て中央部に増肉部１２が形成されているのであ
り、該増肉部１２の大部分は接地側と反対の内面
側に高くなるように形成されているのである。 9 is the center part of the elastic crawler belt, 10 and 11 are both side parts of the elastic crawler track, and the thickness of the elastic material near the end where the two rows of reinforcing bodies 3 and 4 in the belt width direction face each other in the center part 9 is as follows. It is designated by the symbol H 1 , 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 , and the thickened part 12 is formed in the central part. 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、巻掛抵抗はやゝ増大するが、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、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 slightly, the inner surface of the central portion 9 has no irregularities and becomes a flat surface, which is advantageous in terms of soil removal performance and in terms of preventing 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 (H 1 - H 2 ) exists. Most of it 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.
次に、作用を説明すると、弾性履帯１は図外の

けられ、咬合部７，８に係合爪が順次係合するこ

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.

し作用により、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 track E is bent, the distance between the two rows of reinforcing body protrusions becomes shorter, and a dimensional difference between the R of the wheels and the distance dimension A occurs, and along with this dimensional difference, the inclination of the crawler track on the upper side of the step rises. As the angle 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

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.
本発明は以上の通りであり、要するに本発明で

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,
Since most of the thickened portion 12 is formed to be higher on the inner surface side opposite to the ground contact side, 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
厚が、補強体３，４の夫々の外側端部附近の弾性
材料肉厚よりも増肉とされた増肉部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。 An increased thickness 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

でも増肉してないので、重量過大となつたり、接
地圧の低下をきたすこともなく、段差走行、不整

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損なわれること
なく、牽引力の低下を招くことがない等の利点が
ある。 Further, 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 there are advantages such as no reduction in traction force.
