Resilient crawler and method of manufacturing the same

A resilient crawler comprising:

• a crawler body formed of a resilient material in the shape of an endless belt and having a multiplicity of lugs projecting from the outer peripheral surface at intervals longitudinally along the crawler body;
• a multiplicity of linear lateral reinforcing members disposed in the crawler body so as to extend laterally thereof and be arranged longitudinally therealong;
• wherein the volume proportion of said lateral reinforcing members is high at the lateral center of said crawler body and low at the lateral outer portions of said crawler body;
• wherein a plurality of layers of reinforcing members, each of which is formed by arranging a number of said reinforcing members longitudinally along said crawler body, are successively provided in the crawler body in the thicknesswise direction thereof;
• and
• wherein said reinforcing members in each reinforcing member layer are oriented to intersect with each other from layer to layer.

• and
• a multiplicity of linear lateral reinforcing members disposed in the crawler body so as to extend laterally thereof and be arranged longitudinally therealong;
• wherein said lateral reinforcing members are arranged at close intervals with respect to each other in each portion of said crawler body where said lug is formed, and at larger intervals with respect to each other in each portion between said lugs;
• wherein the volume proportion of said reinforcing members is high at the lateral center of said crawler body and low at the lateral outer portions of said crawler body;
• wherein a plurality of layers of reinforcing members, each of which is formed by arranging a number of said reinforcing members longitudinally along said crawler body, are successively provided in the crawler body in the thicknesswise direction thereof;
• and
• wherein said reinforcing members in each reinforcing member layers are oriented to intersect with reinforcing members of adjacent reinforcing member layers.

A resilient crawler comprising:

• a crawler body formed of a resilient material in the shape of an endless belt and having a multiplicity of lugs projecting from the outer peripheral surface at intervals longitudinally along the crawler body;
• a resilient core portion formed of a resilient material provided in the core portion in the lug of the crawler body;
• and
• a multiplicity of lateral reinforcing members buried in the lug along the outer periphery edge of the resilient core portion.
