Rubber crawler belt of a tracked vehicle

A rubber crawler belt for a tracked vehicle, wherein core members are embedded in said rubber crawler belt and arranged so as to engage serially with every tooth of a drive wheel, and each of said core members has an engaging portion for engaging with said drive wheel and which is provided in a widthwise central portion of said core member between a left side portion of said core member and a right side portion of said core member, each of the right side portion and the left side portion being provided with a guide projection, a rolling rail surface and a wing portion, and wherein the front-rear directional dimension A of said engaging portion and the front-rear directional dimension B of said wing portions are approximately the same

• A.apprxeq.B;
• wherein a first plurality of core lines is provided close to a lower surface of each of said core members and a second plurality of core lines is provided close to an upper surface of each of right and left wing portions of each of said core members, said first and second pluralities of core lines being embedded in said rubber crawler belt and extending in the front-rear directions of said rubber crawler belt;
• and
• wherein said rubber crawler belt has a roller-rolling side, and the rubber crawler belt is provided with a preset angle so that rolling rail surfaces of neighboring core members will bend toward the roller-rolling side of the rubber crawler belt.

A rubber crawler belt for use on a tracked vehicle having a drive wheel with teeth, said rubber crawler belt having a left edge and a right edge extending in the belt-winding direction, a first surface for contacting the ground, and a second surface opposite said first surface, said second surface being adapted to contact said drive wheel during operation of the tracked vehicle;

• said rubber crawler belt having a widthwise central portion at least substantially centrally located between said left edge and said right edge, said rubber crawler belt comprising a plurality of core members embedded in an endless rubber belt and extending widthwise of said endless rubber belt, said plurality of core members being arranged in said endless rubber belt so as to be able to serially engage the teeth of a drive wheel which is in contact with said second surface, each of said core members having a left wing portion and a right wing portion, a plurality of engaging holes for engaging with the teeth of the drive wheel, each of said plurality of engaging holes being formed in said widthwise central portion of the rubber crawler belt between a pair of neighboring core members, and at least one lug formed as part of said first surface with each one of said at least one lug extending across the projection planes of a plurality of adjacent core members and gaps between said adjacent core members.
