ELASTIC CRAWLER
Document Type and Number:
Japanese Patent JP2014141130
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress wear of an elastic body projection by suppressing excessive rise of a contact pressure between a wheel and the elastic body projection.SOLUTION: A rubber crawler 10 (sample of an elastic crawler) has: an endless rubber belt 12 (sample of an elastic body) wound around a plurality of wheels; rubber projections 14 (sample of an elastic body projection) formed plurally at intervals in the crawler circumferential direction on the rubber belt 12, and projected to the crawler inner peripheral side, for restricting movement of the wheel to the crawler width direction by having a contact with the wheel rolling along the inner peripheral surface 12A; and a hollow part 24 formed between a center part 14C in the crawler width direction of the rubber projections 14 and a wall part 14X in the width direction, for absorbing input power by being deformed when the wall part 14X in the width direction receives input power from the wheel.
