AI Technical Summary

Technical Problem

The existing elastic track core material is difficult to return to the normal meshing position when it deviates or distorts laterally, resulting in increased resistance and difficult resilience.

Method used

A core material for elastic track buried in an annular track body is designed, including a core material body extending along the width direction of the track, first and second protrusions protruding to the circumference of the track, and the first protrusion has a cross-engagement surface. , plane and curved surface structure, and the second protrusion has a engaging surface, plane and curved surface structure to ensure that it can easily return to the normal engagement position when deviated or distorted.

Benefits of technology

It can quickly and easily return to the normal meshing position when transversely deviate or twisted, reduce the risk of wheel removal such as drive wheels, idler wheels, and improve the stability and traction performance of the track.

Abstract

The invention provides a core material for an elastic track and the elastic track, wherein the core material can easily return to a normal position even when lateral deviation or distortion occurs. The present invention relates to a core material (3) for an elastic track embedded in an endless belt-shaped track body (2) comprising an elastic body. A core material for an elastic track is provided with: a core material main body (8) extending in a second direction (b); a first protrusion (9A) protruding from the core body toward one side in the first direction (a); and a second protrusion (9B) protruding from the core body toward the other side in the first direction at a position further inward (bi) than the first protrusion in the second direction. The first protrusion has a shape protruding toward the outside (BO) in the second direction by a first engagement surface (10A), a first flat surface (11A), and a first curved surface (11B). The second protrusion has a shape protruding inward in the second direction by a second engagement surface (10B), a second flat surface, and a second curved surface (12B).
