WIPO Patent Application WO/2005/073060

Kind Code:

A1

Abstract:

A coreless rubber crawler traveling device capable of providing a spring property by reducing the contact area of the rolling wheel rolling surface of the inner peripheral surface of a rubber elastic body with the outer surfaces of rolling wheels. The traveling device comprises a coreless rubber crawler having the endless rubber elastic body, a main cord row buried therein in the longitudinal direction, rubber projections formed on the inner peripheral surface of the rubber elastic body at specified pitches, and rubber lugs formed on the outer peripheral surface of the rubber elastic body and the rolling wheels. The rolling wheels installed on a frame side on both sides of the rubber projections in the lateral direction are brought into contact with and roll on the inner peripheral surface of the rubber elastic body. The contact area of the inner peripheral rolling surface of the rubber elastic body with the outer surfaces of the rolling wheels is 30 to 70% of the area of the outer surfaces of the rolling wheels.
