Travel Resistance of the Agricultural Rubber Crawler (Part 1)

Rolling Resistance of Track Rollers

Abstract

The mechanism of the inner resistance in a rubber crawler was investigated to reduce the required power. The rolling resistance of the track roller, which is one of the major inner resistance, was measured for seven different weights with the five diameters of the track roller. Three types of the rolling resistance were obtained. As the diameter of the track roller increased, the difference between the maximum and minimum rolling resistances de-creased. It was assumed that the deformation of the rubber crawler has a great effect to the inner resistance of the rubber crawler.
