초록 ▼

A rubber track assembly comprising a driving wheel, an idler wheel, an endless rubber track extending around the driving wheel and the idler wheel and having a plurality of rubber lugs formed on its outer circumference and a plurality of rubber guide projections formed on its inner surface, and a plurality of roller wheels arranged in contact with inner surface of the rubber track in a ground contact region thereof, each of the wheels has a pair of wheel portions formed at its opposite sides and spaced apart to be disposed at opposite sides of the guide projection for engaging the inner surface of the rubber track at the opposite sides of the guide projection. The rubber guide projection is provided with at least one low friction surface having a coefficient of friction lower than that of the rubber material of the rubber guide projection.

A rubber track assembly comprising: a driving wheel; an idler wheel; an endless rubber track extending around the driving wheel and the idler wheel and having a plurality of rubber lugs formed on an outer circumference of the track and a plurality of rubber guide projections arranged on an inner surface of the track at a predetermined distance in a longitudinal direction of the track, each of the rubber guide projections protruding from the inner surface at a central portion in a widthwise direction thereof; and a plurality of roller wheels arranged in contact with the inner surface of the track in a ground contact region thereof wherein each of the driving wheel, the idler wheel and the roller wheels including a pair of wheel portions spaced apart from each other in the widthwise direction of the track, and each of the rubber guide projections is provided with a low friction member having a coefficient of friction lower than that of a rubber material of the rubber guide projection and at least extended through the rubber guide protrusion in the widthwise direction of the track so as to expose opposite end surfaces of the low friction member on opposite side surfaces of the rubber guide projection, said low friction member contacting one of the wheel portions in one of the driving wheel, the idler wheel and the roller wheels in the cornering of the rubber track assembly along a curve to reduce a lateral component of a friction force therebetween to a level sufficiently small to prevent said one of the wheel portions from riding over the rubber guide projection.
