Elastic crawler
View Patent ↗An elastic crawler having a crawler body formed of a rubber elastic material into an endless belt so that rollers rotatively move on right and left side regions in an inner surface of the crawler body is provided with a reinforcement rising in a thickness direction of the crawler body in an area on an outer peripheral surface of the crawler body corresponding to right and left ends of the roller.
1. An elastic crawler comprising a crawler body formed of a rubber elastic material in an endless belt so that each of a series of rollers rotatively move on right and left elastically bendable side regions of an inner surface of the crawler body, said elastically bendable side regions extending outward beyond right and left ends of the rollers in a direction toward a respective circumferential edge of the crawler body and being elastically bendable about an axis that extends in a circumferential direction of the crawler, wherein:
for preventing the elastically bendable side regions from being cracked when either of the side regions of the elastic crawler is bent about said axis that extends in a circumferential direction of the crawler, a reinforcement is provided extending outwardly in a thickness direction of the crawler body in an area on a peripheral surface of the crawler body at least partially under said right and left ends of each of the rollers.
2. The elastic crawler according to claim 1 , wherein said reinforcement is provided in an area on the outer surface of the crawler body corresponding to right and left ends of the roller.
3. The elastic crawler according to claim 1 , wherein said reinforcement is elongated in a circumferential direction.
4. The elastic crawler according to claim 3 , wherein said reinforcement is continuous in a circumferential direction.
5. The elastic crawler according to claim 1 , wherein said crawler body is coreless in said right and left elastically bendable side regions.
