Rubber crawler allowing reducion in vibration

Abstract

The present invention provides a rubber crawler that reduces vibrations that deteriorate ride comfort for an operator and cause malfunctions and malfunctions of electronic devices and the like equipped on operating machines. The rubber crawler is composed of a jointless annular rubber elastic material, core bone, tensile body, and plate teeth. The core bone is embedded in the rubber elastic material at a certain interval in the length direction of the rubber elastic material. The tensile body Surrounding the core bone from the outside and also embedded in the rubber elastic body, the plate teeth are formed on the outer peripheral side of the rubber elastic body with the same pitch as the core bone; the planar shape of the plate teeth at the part opposite to the core bone It is roughly straight in the width direction of the rubber elastic material, and the cross-sectional shape of the teeth in the length direction of the rubber elastic material is a roughly symmetrical trapezoid, and the width of the core bone and the teeth in the length direction of the rubber elastic material is approximately Equally, the positions of the plate teeth are arranged in a shifted direction in the direction opposite to the advancing direction.

Description

technical field [0001] The present invention relates to a new structure of a rubber crawler, and more specifically, provides a rubber crawler that reduces vibration during walking. Background technique [0002] Running gear using rubber tracks is widely used in agricultural machinery, construction operation machinery, and the like. In addition, the rubber crawler track is formed of a rubber elastic material into a jointless ring, and is hung on the driving wheel, the road wheel, and the driven wheel to perform a revolving motion. The driving wheel, the road wheel, and the driven wheel are separated by a shaft. It is remotely installed on the vehicle equipped with the rubber crawler walking device. [0003] figure 1 It is a top view of the contact surface side of a conventional rubber track, figure 2 Yes figure 1 The a-a line sectional view. in addition, image 3 A state in which drive wheels 31 and road wheels 32 of the traveling device using the rubber crawler 21 are...

AI Technical Summary

Problems solved by technology

The vibration generated by the vertical movement of the road wheel 32 is due to the large difference in rigidity between the high rigidity part 28 and the low rigidity part 29.
