COOLING PIN STRUCTURE FOR SHOE BODY OF TANK

摘要

PURPOSE: A cooling pin structure of a shoe body for a tank is provided to radiate rapidly heat in a rubber pad by forming cooling pins in the shape of a plate to a metal surface combined to the rubber pad. CONSTITUTION: A cooling pin(40) is formed to an upper concave groove portion(30) of a shoe body(24) to radiate heat accumulated on a wheel side pad outside by contacting the shoe body of a caterpillar to a driving wheel. The cooling pin is molded integrally to the shoe body to longitudinal or cross directions. The cooling pin is welded to the upper concave groove portion of the shoe body by cutting a plate. Therefore, life span of a floor pad(34) and the wheel side pad is extended by radiating heat after increasing a contacting area of air with the cooling pin.
