Side rolling friction turning plastic caterpillar track

The utility model provides a side rolling friction turning plastic caterpillar track. The side rolling friction turning plastic caterpillar track comprises a conveying caterpillar track body. The two lateral sides, parallel to the moving direction of the conveying caterpillar track body, of the conveying caterpillar track body are at least symmetrically provided with a pair of idler wheels, and the axes of the idler wheels are perpendicular to the moving direction of the conveying caterpillar track body. When the conveying caterpillar track body is dragged by drive sprockets to conduct turning conveying motion on curved tracks, the idler wheels on the pressed side of the conveying caterpillar track body are tightly attached to the convex working faces of the curved rails and roll, and the idler wheels on the other side symmetrical to the pressed side are in a free state. The two lateral sides, parallel to the conveying direction of the conveying caterpillar track body, of the conveying caterpillar track body are at least symmetrically provided with a pair of idler wheels, when the conveying caterpillar track body is operated, the conveying caterpillar track body and the tracks are in rolling friction contact, the friction coefficients between the conveying caterpillar track body and the tracks are effectively decreased, turning conveying stability is improved, and meanwhile the service life of the whole plastic conveying caterpillar track is relatively prolonged.
