Description

【０００１】
【発明の属する技術分野】
本発明はゴムクローラの新規な構造に関し、更に詳しくは、走行時の振動を低減したゴムクローラを提供するものである。
【０００２】
【従来の技術】
ゴムクローラを用いた走行装置は、農業機械、建設作業機械等に広く用いられている。そして、ゴムクローラはゴム弾性材によって無端状に形成され、かかるゴムクローラ走行装置が装着される車両に軸間距離をおいて取り付けられた駆動輪、転輪、従動輪に巻き掛けられ回走するものである。
【０００３】
図１は従来のゴムクローラの接地面側の平面図であり、図２はａ−ａ線断面図である。又、図３はゴムクローラ２１を用いた走行装置における駆動輪３１及び転輪３２とゴムクローラ２１が接触している状態を示している。ここで示すようにゴムクローラ２１の本体２２の外面にラグ２３が帯長手方向に間隔をおいて複数形成されている。この巻き掛けの状態において、ゴムクローラ２１は駆動輪３１によって動力が伝達されて回走するわけであるが、このゴムクローラ２１の回走に従い巻き掛け部のラグ２３は地面に順次接触することになる。
【０００４】
このとき、ラグ２３の頂面の縁部２４が地面に最初に衝突し、これにより衝撃が生じ、さらにラグ２３（縁部２４）が順次接地していくことでこの衝撃が繰り返し生じて振動となり、ゴムクローラ２１はスムーズな回走とならないという問題点があった。勿論、転輪３２のゴムクロ−ラ内周面の転がりによって、より大きな振動が生じることは言うまでもない。
【０００５】
通常、ゴムクローラ２１の本体２２の内部には芯金２５がラグ２３の位置に対応して埋設されており、ラグ２３及び芯金２５が重なり合う部分は高剛性部２８となっている。一方、帯長手方向におけるラグ２３同士の間隔内における本体２２部分は、ラグ２３も芯金２５もないため、高剛性部２８よりも低剛性部２９となっている。
【０００６】
従って、転輪３２が高剛性部２８上にあるときのゴムクローラ２１の上下方向における変形量と低剛性部２９上にあるときの該変形量とでは、低剛性部２９上にあるときの変形量の方が大きく変形量に差がもたらされる。従って、転輪３２はゴムクローラ走行装置が走行しているときには変形差の分だけ上下運動をすることになり、この上下運動によって振動が生じていた。このように転輪３２が上下運動をすることによって生じる振動は高剛性部２８と低剛性部２９の剛性の差が大きいことが原因であった。尚、以上の図にあって、２６は図示しないスプロケットとの係合穴、２７は芯金２５に形成され、ゴムクロ−ラ２１の内周側に突出する突起である。
【０００７】
【発明が解決しようとする課題】
ゴムクローラ走行装置によって生じる振動は、操縦者にとって乗り心地が悪く、またこの振動によって、作業機械に装備された電子機器等の故障、誤作動の原因となっていた。本発明は、走行中に発生する振動を低減することができるゴムクローラを提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明の要旨は、無端状ゴム弾性材と、該ゴム弾性材の長手方向に一定ピッチをもって埋設された芯金と、この芯金を外囲いして同様にゴム弾性体内に埋設された抗張体と、ゴム弾性体の外周側に芯金のピッチと同じピッチをもって形成されたラグとよりなるゴムクロ−ラであって、芯金と対向する部位のラグの平面形状がゴム弾性材の幅方向にほぼ直線をなし、ゴム弾性材の長手方向におけるラグの断面形状が左右ほぼ対称の台形状で、芯金とラグとのゴム弾性材の長手方向における幅がほぼ同一であり、当該ラグの位置を進行方向と逆の方向にずらして配置したことを特徴とする振動を低減したゴムクローラにかかるものである。
【０００９】
そして、具体的には、ラグの位置が、１／６〜１／３ピッチだけ進行方向と逆の方向にずらして配置したもので、更に言えば、ラグの頂面が、芯金とほぼ重ならない範囲でずらして配置したゴムクローラである。
【００１０】
【発明の実施の形態】
上記の従来例にて説明したように、ゴムクローラを用いた走行装置にあっては、機械の駆動力は、駆動輪、芯金、ラグ、地面の順で伝わるが、走行時の振動はこれとは逆の経路をたどって機体に伝達される。特に、芯金のピッチとラグのピッチを等間隔で平面視で同位置に対向して配置する従来のゴムクローラでは、ラグと芯金とが高剛性部を形成しているため、走行中のラグの頂面の縁部が接地する際の力が芯金に伝わりやすいのが現実であった。
【００１１】
これは、ラグの頂面の縁部が接地する際、ラグがゴム弾性変形を起こしても芯金と対向して配置されているために、接地面側からの例えば走行面の凹凸による振動は芯金に直接的に伝わってしまうことになる。
【００１２】
本発明はかかるゴムクローラの芯金とラグとの関係を見直し、駆動力の伝達を疎外することなく、振動の発生を低減しようとしたものであり、芯金とラグの配置にあって、ラグの位置を進行方向と逆の方向にずらして配置し、ラグの頂面の縁部が接地した際にその振動が芯金に直接伝わらないように低剛性部側に配置し、ラグの変形を容易としたものである。即ち、ずらした分だけラグの動きが許容され、その分高剛性部分の剛性が低下して、低剛性部分の剛性の差を小さくして両者を近づけ、転輪が上下動による振動を低減することができることになる。
【００１３】
尚、ラグの配置をずらした場合であっても、ラグの頂面の縁部が接地した際にラグは変形するためある程度の効果はあるが、両者が共に高剛性部を構成していない方が好ましく、その振動が直接芯金に伝わることのない構造、即ち、ラグの頂面（の縁部）と芯金とが平面視で重なり合わない構造が好ましい。
【００１４】
尚、ゴムクローラ走行装置を装備して走行に供した場合、荷重が大きく加わるのはゴム弾性材の幅方向中央部である。従って、この部位のラグのみを上記のようにずらすことによっても効果がもたらされる。
【００１５】
【実施例】
以下、本発明を図面をもって更に詳細に説明する。図４は本発明のゴムクロ−ラの接地面側の平面図であり、図５はそのＡ−Ａ線断面図である。図中、１は本発明のゴムクロ−ラであり、２は無端状のゴム弾性材、３は外周側に形成されたラグ、４はラグ３の頂面の縁部である。５はゴム弾性材２中に一定ピッチで埋設された芯金、６は駆動輪の歯との係合穴である。この例におけるラグ３は係合穴６を挟んで左右に分断されてはいるが、芯金５と対応して幅方向に一直線をなす形状をなし、長手方向の断面はほぼ台形状をなしている。尚、ゴム弾性材２の長手方向に向けて埋設されたスチールコードは図示しない。
【００１６】
さて、ここで示したゴムクローラ１にあって、ラグ３はゴム弾性材１の幅方向にほぼ直線をなし、ゴム弾性材１の長手方向におけるラグの断面形状は左右ほぼ対称形の台形をなしている。そして、芯金５との関係にあっては、ゴム弾性材１の長手方向における幅がほぼ同一である。かかるラグ３にあって、その位置を（芯金５に対し）ゴムクローラの進行方向と逆の方向に約１／４ピッチずらして配置したものである。この場合、ラグ３の頂面が、芯金５と重ならない範囲でずらして配置するべきである。
【００１７】
図６は上記ゴムクローラ１をもって駆動輪１１、転輪１２、図示しない遊動輪に巻き掛けして走行装置とした際の状態を示すものである。そして、特に転輪１２との関係にあっては、本来であれば高剛性部分を構成する芯金５とラグ３との重なり部位に至り、ラグ３が進行方向とは逆側にずらされているため、ここに至ってもそのままストレートに剛性の高い部位に乗り上げるものではなく、ラグ３を後退させてあるため剛性が低くなり、かかるラグ３の頂面の縁部４が走行面に接触する際にも、これが芯金５と重なり合っていないため、その動きは芯金５によって大きくは規制されずに動くことができ、これによってもこの部位の剛性の低減がもたらされることになる。
【００１８】
一方、ラグ３は進行方向とは逆側にずらされているため、低剛性部分にはみ出しており、今度は逆にこの部位の剛性のアップにつながることになる。従って、両者の剛性の差が小さくなり、転輪１２の上下動が少なくなり、振動の発生が低減されることになる。
【００１９】
図７は本発明のゴムクロ−ラの第２実施例を示す接地面側の平面図である。この例にあっては、ラグ３は係合穴６を挟んで左右に分断されたものであり、その一方側（この図では右側）のみをゴムクロ−ラの進行方向に対して逆側にずらした例である。ゴムクローラを車両に装着した際、場合によっては車両の内側と外側とでは振動をもたらす程度が異なることもあり、これに対処するものである。勿論、振動に大きな影響がある側にラグ３をずらした側をもって装着するものである。
【００２０】
【発明の効果】
以上の通り、本発明のゴムクロ−ラを装着した走行装置にあっては、ゴムクローラの長手方向にあって、全体として剛性の差が小さくなり、このため、駆動輪に巻き掛けされて接地する際の振動や転輪がゴムクロ−ラの内周面を転動する際の上下動が小さくなり、これによって振動が低減されることになった。

BACKGROUND OF THE INVENTION
The present invention relates to a novel structure of a rubber crawler, and more specifically, provides a rubber crawler with reduced vibration during traveling.
[0002]
[Prior art]
A traveling device using a rubber crawler is widely used in agricultural machines, construction work machines, and the like. The rubber crawler is formed endlessly by a rubber elastic material, and is wound around a drive wheel, a wheel, and a driven wheel that are attached to a vehicle on which the rubber crawler traveling device is mounted at an inter-axis distance. Is.
[0003]
FIG. 1 is a plan view of a conventional rubber crawler on the ground contact surface side, and FIG. 2 is a cross-sectional view taken along the line aa. FIG. 3 shows a state in which the rubber wheels 21 are in contact with the drive wheels 31 and the rollers 32 in the traveling device using the rubber tracks 21. As shown here, a plurality of lugs 23 are formed on the outer surface of the main body 22 of the rubber crawler 21 at intervals in the belt longitudinal direction. In this state of wrapping, the rubber crawler 21 is rotated by the power transmitted by the drive wheel 31. As the rubber crawler 21 rotates, the lug 23 of the wrapping portion sequentially contacts the ground. Become.
[0004]
At this time, the edge 24 of the top surface of the lug 23 first collides with the ground, and this causes an impact, and the lug 23 (the edge 24) is sequentially grounded, and this impact is repeatedly generated and becomes a vibration. The rubber crawler 21 has a problem that it cannot be smoothly turned. Of course, it is needless to say that greater vibration is generated by rolling of the inner surface of the rubber track of the roller 32.
[0005]
Usually, a cored bar 25 is embedded in the main body 22 of the rubber crawler 21 corresponding to the position of the lug 23, and a portion where the lug 23 and the cored bar 25 overlap is a highly rigid portion 28. On the other hand, the main body 22 portion in the interval between the lugs 23 in the longitudinal direction of the band is the lower rigidity portion 29 than the higher rigidity portion 28 because neither the lug 23 nor the cored bar 25 is present.
[0006]
Therefore, the amount of deformation in the vertical direction of the rubber crawler 21 when the roller wheel 32 is on the high-rigidity portion 28 and the amount of deformation when the roller wheel 32 is on the low-rigidity portion 29 are The amount is larger and the amount of deformation is different. Accordingly, when the rubber crawler traveling device is traveling, the wheel 32 moves up and down by the difference in deformation, and vibration is generated by this up and down motion. Thus, the vibration generated by the vertical movement of the rolling wheel 32 is caused by a large difference in rigidity between the high-rigidity portion 28 and the low-rigidity portion 29. In the above drawings, 26 is an engagement hole with a sprocket (not shown), and 27 is a protrusion formed in the cored bar 25 and protruding toward the inner peripheral side of the rubber crawler 21.
[0007]
[Problems to be solved by the invention]
The vibration generated by the rubber crawler traveling device is uncomfortable for the operator, and this vibration causes a failure or malfunction of an electronic device or the like installed in the work machine. An object of this invention is to provide the rubber crawler which can reduce the vibration which generate | occur | produces during driving | running | working.
[0008]
[Means for Solving the Problems]
The gist of the present invention is that an endless rubber elastic material, a core metal embedded at a constant pitch in the longitudinal direction of the rubber elastic material, and a tensile material that surrounds the core metal and is similarly embedded in the rubber elastic body. Body and a lug formed on the outer peripheral side of the rubber elastic body with a lug formed at the same pitch as that of the core metal, and the planar shape of the lug at the portion facing the core metal is the width direction of the rubber elastic material The cross-sectional shape of the lug in the longitudinal direction of the rubber elastic material is substantially a symmetrical trapezoidal shape, and the width of the rubber elastic material in the longitudinal direction of the rubber elastic material is substantially the same, and the position of the lug Is a rubber crawler with reduced vibration, characterized in that it is shifted in the direction opposite to the traveling direction.
[0009]
Specifically, the position of the lug is shifted by 1/6 to 1/3 pitch in the direction opposite to the traveling direction. More specifically, the top surface of the lug is substantially overlapped with the core metal. It is a rubber crawler that is shifted in a range that does not become necessary.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
As explained in the above-mentioned conventional example, in the traveling device using the rubber crawler, the driving force of the machine is transmitted in the order of the driving wheel, the core metal, the lug, and the ground, but the vibration during traveling is this. It is transmitted to the aircraft following the reverse path. In particular, in the conventional rubber crawler in which the pitch of the metal core and the pitch of the lug are arranged at equal intervals and facing each other in plan view, the lug and the metal core form a high-rigidity portion. The reality is that the force when the edge of the top surface of the lug touches down is easily transmitted to the cored bar.
[0011]
This is because when the edge of the top surface of the lug contacts the ground, even if the lug is elastically deformed, the lug is arranged facing the cored bar. It will be transmitted directly to the mandrel.
[0012]
The present invention has reviewed the relationship between the core metal and lug of such a rubber crawler and tried to reduce the occurrence of vibration without alienating the transmission of the driving force. The position of is shifted in the direction opposite to the direction of travel, and when the edge of the top surface of the lug touches the ground, it is placed on the low-rigidity side so that the vibration is not directly transmitted to the core, and the lug is deformed. It is easy. That is, the movement of the lug is allowed by the amount of displacement, the rigidity of the high-rigidity part is reduced by that amount, the difference in rigidity of the low-rigidity part is reduced and the two are brought closer together, and the wheels reduce vibration due to vertical movement. Will be able to.
[0013]
Even if the lug is shifted, there is some effect because the lug deforms when the edge of the lug's top surface contacts the ground, but both do not constitute a high-rigidity part. A structure in which the vibration is not directly transmitted to the core metal, that is, a structure in which the top surface (the edge portion) of the lug and the core metal do not overlap in a plan view is preferable.
[0014]
In addition, when equipped with a rubber crawler traveling device and used for traveling, the load is greatly applied at the central portion in the width direction of the rubber elastic material. Therefore, the effect can be obtained by shifting only the lug of this portion as described above.
[0015]
【Example】
Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 4 is a plan view of the rubber crawler of the present invention on the ground contact surface side, and FIG. 5 is a sectional view taken along the line AA. In the figure, 1 is a rubber track of the present invention, 2 is an endless rubber elastic material, 3 is a lug formed on the outer peripheral side, and 4 is an edge of the top surface of the lug 3. Reference numeral 5 denotes a cored bar embedded in the rubber elastic material 2 at a constant pitch, and reference numeral 6 denotes an engagement hole with a tooth of the drive wheel. The lug 3 in this example is divided to the left and right across the engagement hole 6, but forms a straight line in the width direction corresponding to the cored bar 5, and the longitudinal section has a substantially trapezoidal shape. Yes. The steel cord embedded in the longitudinal direction of the rubber elastic material 2 is not shown.
[0016]
In the rubber crawler 1 shown here, the lug 3 is substantially straight in the width direction of the rubber elastic material 1, and the cross-sectional shape of the lug in the longitudinal direction of the rubber elastic material 1 is a substantially symmetrical trapezoid. ing. And in the relationship with the metal core 5, the width | variety in the longitudinal direction of the rubber elastic material 1 is substantially the same. In the lug 3, the position (with respect to the core metal 5) is shifted by about 1/4 pitch in the direction opposite to the traveling direction of the rubber crawler. In this case, the top surface of the lug 3 should be shifted so as not to overlap the cored bar 5.
[0017]
FIG. 6 shows a state where the rubber crawler 1 is wound around the driving wheel 11, the rolling wheel 12, and an idle wheel (not shown) to form a traveling device. In particular, in the relationship with the wheel 12, the core 5 and the lug 3, which originally constitute a highly rigid portion, are overlapped, and the lug 3 is shifted to the opposite side of the traveling direction. Therefore, even if it reaches here, it does not run straight on the portion having high rigidity, but the lug 3 is retracted, so that the rigidity becomes low, and the edge 4 on the top surface of the lug 3 comes into contact with the traveling surface. Moreover, since this does not overlap with the cored bar 5, its movement can move without being largely regulated by the cored bar 5, and this also leads to a reduction in the rigidity of this part.
[0018]
On the other hand, since the lug 3 is shifted to the opposite side to the traveling direction, the lug 3 protrudes into the low-rigidity portion, which in turn leads to an increase in the rigidity of this portion. Therefore, the difference in rigidity between the two becomes small, the vertical movement of the wheel 12 decreases, and the occurrence of vibration is reduced.
[0019]
FIG. 7 is a plan view of the grounding surface side showing a second embodiment of the rubber track of the present invention. In this example, the lug 3 is divided into right and left with the engagement hole 6 interposed therebetween, and only one side (right side in this figure) is shifted to the opposite side to the traveling direction of the rubber track. This is an example. When a rubber crawler is mounted on a vehicle, the degree of vibration may be different between the inside and the outside of the vehicle depending on the situation. Of course, the lug 3 is mounted on the side where the lug 3 is shifted to the side having a great influence on the vibration.
[0020]
【The invention's effect】
As described above, in the traveling device equipped with the rubber track of the present invention, the difference in rigidity is small as a whole in the longitudinal direction of the rubber crawler, so that it is wound around the driving wheel and grounded. The vertical movement and the vertical movement when the rolling wheel rolls on the inner peripheral surface of the rubber crawler are reduced, thereby reducing the vibration.
