rubber track

Abstract

The invention provides a rubber track, which will not increase vibration of a running vehicle to be assembled and can reduce traces of a roller running part. The rubber track assembled in a track type driving vehicle comprises a track body in the shape of a circular belt, core rods which are disposed at the periphery of the track body at intervals and are embedded in the track body, and a roller driving face which is disposed at the surface of the inner periphery side. The distances from the center to two sides are equal with respect to the width direction. The roller driving face circles along the circumference and intersects with the core rod in a three-dimensional manner and enables the roller to rotate. The track body is composed of a surface rubber and an inner rubber whose hardness is 5-12 degree harder than the surface rubber. The inner rubber is configured in that when observed from the inner periphery side, the inner rubber contacts with the surface of a roller driving face side of the core rod, overlapping with the roller driving face. The average thickness (T1) of a cross section of the core rod is 10-35% of a roller driving face distance (T2) between the core rod of equal-dividing face and the roller driving face in a width direction.

Description

technical field [0001] The present invention relates to a rubber crawler used in tracked vehicles of agricultural machines such as combines and tractors, and construction machines such as backhoes. Background technique [0002] Crawler-type traveling vehicles (hereinafter sometimes referred to as "traveling vehicles") such as agricultural machinery such as combines and tractors, and construction machinery such as backhoes are equipped with devices embedded at equal intervals in the circumferential direction (circulation direction). Mandrel rubber tracks. Such a rubber track embedded with a mandrel will damage the rubber covering the mandrel (also known as the rubber track) when the sand, stone, etc. Stains, cuts) and cracks. [0003] If the cracks generated in the rubber continue to develop, the mandrel is exposed and rusted, and the mandrel soon falls off, which significantly reduces the durability of the rubber track. [0004] In order to prevent problems such as peelin...

AI Technical Summary

Problems solved by technology

[0003] If the cracks generated by the rubber continue to develop, the mandrel will be exposed and rusted, so the mandrel will fall off soon, and the durability of the rubber track will be significantly reduced.
