In the figure, 7 is a lug arranged on the outer peripheral surface of the crawler body 6, (c) is a bottom surface of a valley portion formed between the opposing lugs 7, (d) is a slope portion of the valley portion, ) Is a protrusion provided on the bottom surface (c).

In the figure, 11 is a lug, 12 is a thin plate layer embedded inside the lug 11, and (i) is a bottom part. FIG. 6 is a sectional view taken along the line EE of FIG.

【0008】 次に、本考案のゴムクローラの構成を図1〜図6について述べる。図1及び図 2において、クローラ本体6の外周面に設けたラグ7の相対するラグ7間に形成 された谷部の底面部(ハ)に、たとえば高さ5mmの突出部(ホ)を形成し、図3 及び図4では、上記谷部の斜面部(ト)に凹穴(チ)を設け、その深さを上記底 面部(ヘ)よりたとえば5mmの位置に設定し、また図5及び図6では、ラグ11 の内部にクロ−ラ本体10とは色の異なる薄板層12を底面部(リ)と平行に埋 設し、その薄板層12の外側表面を底面部(リ)よりたとえば5mmの位置に設定 して、構成した。Next, the structure of the rubber crawler of the present invention will be described with reference to FIGS. In FIG. 1 and FIG. 2, for example, a protrusion (e) having a height of 5 mm is formed on the bottom surface (c) of the valley formed between the opposing lugs 7 provided on the outer peripheral surface of the crawler body 6. However, in FIGS. 3 and 4, a concave hole (h) is provided in the slope part (g) of the valley part, and the depth thereof is set to, for example, a position of 5 mm from the bottom part (f). In FIG. 6, a thin plate layer 12 having a color different from that of the chlora body 10 is embedded in the lug 11 in parallel with the bottom surface portion (i), and the outer surface of the thin plate layer 12 is formed, for example, from the bottom surface portion (i). It was set at a position of 5 mm and configured.

【0009】 次に、本考案のゴムクローラの作用について述べる。オペレータが機械を運転 して走行または掘削等の作業をするとき、稼働時間の経過とともにラグの摩耗が 進み、機械の牽引力が低下するとともにスリップしやすくなって、ときには安全 上問題であった。したがって建設・作業用車両メーカーとしては、機械の牽引力 を低下させず、安全な作業を確保するためにラグの摩耗限度を谷部の底面部より たとえば5mm程度に規定している。しかし従来のゴムクローラでは、その摩耗限 度を視認する手段がクローラ本体に講じられてなく、交換する時期もオペレータ によってまちまちである。本考案では、ゴムクローラの使用限度を視認する3つ の手段を案出した。1つは、谷部の底面部に突出部を設ける構造である。ラグが 摩耗によって徐々に減り、ラグ表面と突出部表面が面一になった時点が使用限度 である。2つは、谷部の斜面部に凹穴を設ける構造である。摩耗によって凹穴は 徐々に浅くなっていき、凹穴の底面とその外周面とが面一になった時点が使用限 度である。3つは、ラグの内部にクローラ本体とは色の異なる薄板層を埋設する 構造である。ラグの摩耗が進み、薄板層が露出した時点が使用限度である。この ようにクローラ本体に上記突出部、凹穴及び薄板層のいずれかを設けることによ って、オペレータがゴムクロ−ラの使用限度、すなわち交換時期を確実に視認す ることができる。また上記突出部、凹穴、薄板層は複数ピッチおきに配設しても よい。Next, the operation of the rubber crawler of the present invention will be described. When the operator operates the machine to perform work such as traveling or excavation, the wear of the lug progresses with the lapse of operating time, the traction force of the machine decreases, and slippage easily occurs, which is sometimes a safety issue. Therefore, as a construction and work vehicle manufacturer, the wear limit of lugs is specified to be, for example, about 5 mm from the bottom of the valley to ensure safe work without reducing the traction force of the machine. However, in the conventional rubber crawler, the crawler body is not provided with a means for visually recognizing the wear limit, and the operator changes the time for replacement. The present invention has devised three means for visually recognizing the usage limit of the rubber crawler. One is a structure in which a protrusion is provided on the bottom surface of the valley. The usage limit is when the lugs are gradually reduced due to wear and the lug surface and the surface of the protrusion are flush with each other. The second is a structure in which a concave hole is provided in the slope of the valley. The recess gradually becomes shallower due to wear, and the usage limit is when the bottom surface of the recess and the outer peripheral surface are flush with each other. The third is a structure in which a thin plate layer different in color from the crawler body is embedded inside the lug. The limit of usage is when the lug wear progresses and the thin plate layer is exposed. By thus providing the crawler body with any one of the above-mentioned protruding portion, recessed hole and thin plate layer, the operator can surely visually check the usage limit of the rubber crawler, that is, the replacement time. Further, the protrusions, the recesses, and the thin plate layers may be arranged at a plurality of pitches.

【0010】[0010]

【考案の効果】[Effect of device]

建設・作業用車両に装着されるゴムクローラは、使用していくうちにラグは摩 耗により徐々に減っていく。そのラグが過少になったり、無くなったりすれば、 必然的に機械の牽引力は低下し、スリップしやすくなって、ときには安全上問題 であった。ところが従来技術のゴムクローラは、オペレータにとってその摩耗限 度を視認する目安がなかったので、交換時期がよく分からなかった。本考案では 、ゴムクローラの摩耗限界を知らせる突出部、凹穴、薄板層のいずれかをクロー ラ本体に設けることにより、オペレータは、ゴムクローラの交換時期を確実に知 ることができる。したがってオペレータは、機械の性能及び安全性の確保とゴム クローラのメンテナンス性の向上を図ることができる。 Rubber crawlers installed in construction and work vehicles gradually wear down as the lugs wear down. If the lug becomes too small or disappears, the traction force of the machine will inevitably decrease and it will easily slip, which is sometimes a safety issue. However, with the rubber crawler of the prior art, there was no standard for the operator to visually recognize the wear limit, so it was not clear when to replace it. According to the present invention, the operator can surely know the replacement time of the rubber crawler by providing the crawler body with any one of the protruding portion, the recessed hole, and the thin plate layer for notifying the wear limit of the rubber crawler. Therefore, the operator can ensure the performance and safety of the machine and improve the maintainability of the rubber crawler.
