An elastic pedrail

Abstract

Disclosed is an elastic crawler formed with an elastic material in the shape of an endless track, and used as the wheel for the work vehicle with enhanced reliability and durability. The elastic crawler includes a crawler body 2A formed with an elastic material and having lugs 4L, 4R, 5L and 5R protruded at the ground contact side thereof, and cores having wings 3L and 3R extended left and right to the center of the crawler body in the width direction thereof, and arranged parallel to each other in the longitudinal track direction of the crawler body such that the wings face the lugs formed at the crawler body. The crawler body has first and second lug units alternately arranged parallel to each other in the longitudinal track direction thereof (in the direction of Y1 and Y2). The first lug unit has left lugs 4L facing each other over two wings, and right lugs 4R arranged right to the center of the crawler body while proceeding symmetrical to the left lugs around the center. The second lug unit has left lugs 5L facing each other over one wing, and right lugs 5R arranged right to the center of the crawler body while proceeding symmetrical to the left lugs around the center.

Description

technical field [0001] The present invention relates to an elastic crawler, in particular to an elastic crawler made of elastic material and in the form of an endless track, which is used under severe working conditions, such as steep and uneven On the road - the wheels of the working engineering vehicle (work vehicle). Background technique [0002] Generally, iron chains are commonly used as wheels of construction vehicles working under severe working conditions, such as on steep and uneven roads. However, due to the heavy weight, poor fuel consumption, and high noise of the chains, elastic crawlers have recently been introduced to replace the chains. [0003] The elastic track has a track body and core. The track body is made based on elastic material and its shape is an endless track. The core is embedded in the track body, and has left and right wings extending from the center of the track body to the left and right sides, that is, in the width direction of the track ...

Problems solved by technology

For this reason, although it is slightly improved, it is impossible to obtain sufficient flexibility and completely eliminate the factor of track loosening.
