Abstract
The present invention provides an elastic crawler having an improved flexing properties in which arrangement of lugs are improved so as to prevent deterioration of the flexing properties due to rigidity of a crawler body increased by providing lugs. The crawler comprises a crawler body 2, a plurality of core members 3having right and left wings 3R, 3L, respectively, and provided in the crawler body laterally with respect to the crawler and in parallel to each other with a space therebetween in the longitudinal direction of the crawler, and a plurality of right and left lugs including small lugs provided correspondingly to one of the wings 3R or 3L and large lugs provided correspondingly to two of the wings 3R or 3L adjacent to each other in the longitudinal direction of the crawler.
Claims8
An elastic crawler, comprising a crawler body formed of an elastic material into an endless band;
- a plurality of core members having right and left wings, respectively, and provided in the crawler body laterally with respect to the crawler body and in parallel to each other with a space therebetween in the longitudinal direction of the crawler;
- and a pair of right and left lugs raised at positions overlapping projected planes of the right and left wings, respectively, on a ground-contacting surface of the crawler body on the right and left sides of a center in a widthwise direction of the crawler body,
- wherein one of the pair of right and left lugs has a ground-contacting surface extending to and overlapping projected planes of a plurality of right or left wings on the same side as the lug adjacent each other in a longitudinal direction of the crawler and having a ground-contacting length in a circumference direction of the crawler, while the other lug has a ground-contacting surface overlapping a projected plane of one of the right and left wings on the same side as the lug and having another ground-contacting length in the circumference direction, the ground-contacting length of the latter lug being formed shorter than that of the former lug so that the ground-contacting surfaces of the pair of right and left lugs are different in the ground-contacting length, the pair of right and left lugs having the ground-contacting surfaces different in the ground-contacting lengths being alternately arranged in the longitudinal direction of the crawler so as to be staggered along the crawler.
