The elastic crawler () according to this disclosure comprises: an endless belt-like main body () having elasticity; a plurality of cores () embedded in a circumferential direction of the main body (); a plurality of lugs () each being arranged in a manner protruding from an outer circumferential surface of the main body () and extending between the plurality of cores () adjacent in the circumferential direction of the main body (); and an inner circumferential concavity (G) formed at a position on an inner circumferential surface of the main body () overlapping, in a thickness direction of the main body (), an outer circumferential concavity (G) of each of the lugs (). The elastic crawler device comprises: the elastic crawler (); and a drive wheel, an idle wheel and a rolling wheel.

Elastic crawler and elastic crawler device

Provided is an elastic crawler with improved transmission of the driving force to snow, soft ground, etc. by improving the packing performance during running of the elastic crawler. The elastic crawlercomprises: a crawler main bodyformed into an endless shape with an elastic body; a plurality of coresbeing embedded in the crawler main bodyin a manner spaced from each other in the crawler circumferential direction and extending in a crawler width direction; and a plurality of lugsraised from an outer circumferential surface of the crawler main bodyand respectively surrounding predetermined regions R overlapping the coresin a crawler thicknesswise view.

Elastic crawler

A segment structure mounted on a wheel or an endless rubber track for increasing the driving force of off-road vehicles, civil engineering machines or construction machines is disclosed. A segment of a rubber elastic material mounted on the outer periphery of the wheels or the endless rubber track includes a bottom section adapted to be in contact with the wheel or the endless rubber track, a hollow section formed in the segment along the width of the wheel or the endless rubber track, and a stopper erected into the hollow section from the bottom section. The inner surface of the hollow section and the stopper are kept out of contact with each other under a static load.
