<p>PURPOSE:To improve heat radiation performance and secure the long service life of an elastic body by installing the circular pieces as cooling fins in a specific form onto the side surface of a tire part excluding a wheel flange part, in a compression-type elastic wheel having an elastic body interposed between a tire and a ring core. CONSTITUTION:A plurality of fitting concaved parts are arranged onto the inner peripheral surface of a tire 1 and the rim outer peripheral surface of a ring core 2, and a rubber elastic body 3 constituted of rubber blocks is fitted into each fitting concaved part. Cooling fins 4 are arranged in multilayer form onto the side surface of the tire 1. In this case, the cooling fin 4 is formed by arranging a number of circular-plate-shaped fin pieces onto the circles having different diameter, for example, into annular form constituted at least one stripe of in zigzag form. Therefore, the temperature rise of the tire 1 due to the heat generation on brake application can be reduced markedly by the cooling fins 4, and the reduction of the life of the elastic body 3 due to heat radiation can be suppressed.</p> |
