ENDLESS TRACK BELT FOR SNOW MOBILE

摘要

An endless track belt for snow mobile, having an enhanced tractive effect and durability, comprising (1) an endless substrate belt to be traveled along a closed track, on a lower half portion of which an endless track belt comes into contact with the snow stratum to move a snow mobile forward; (2) a plurality of tractive projections formed on the substrate belt at predetermined intervals, and extending at right angles to the traveling direction of the substrate belt; (3) transversal rigid members in the same number as that of the tractive projection extending along the tractive projections, the individual tractive projection and the corresponding transversal rigid member satisfying the relationship such that, when a portion of the substrate belt located in the lower half portion of the closed track is in an angle of zero or .theta. to the horizontal line, the pointed end portion of the individual tractive projection arranged on the above-mentioned portion of the substrate belt is positioned within a shadow region of the corresponding transversal rigid member cast in the direction of an angle of zero or 1/2 .theta. to the perpendicular line.
