Abstract
Official abstract text for this publication.
A crawler track where damage to drive lugs is reduced is provided. Grooves ( 26 ) in the circumferential direction of the crawler track ( 10 ) are arranged at the roots of the drive lugs ( 24 ). Thereby, tensile strain or compressive strain occurring in the roots of the drive lugs ( 24 ) when the crawler track ( 10 ) is wrapped over a wheel ( 14 ) etc. can be alleviated. Further, when the crawler track ( 10 ) meanders, a lateral load causes lateral pressure from the wheel ( 14 ) to a drive lug ( 24 ), producing tensile strain in the root of the drive lug ( 24 ). However, such tensile strain can be alleviated because the wheel ( 14 ) does not come into contact with the drive lugs ( 24 ) in the meandering movement.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber crawler track comprising: an endless belt-shaped rubber resilient body configuring an endless track; a plurality of protrusions provided protruding from the inner peripheral face of the rubber resilient body at uniform intervals along the circumferential direction thereof; and grooves located at the roots of the protrusions and formed in a wheel-passing face that a wheel follows in motion, and. during driving of the rubber crawler track,…
