Abstract

resumo da patente de invenção para: “estrutura de sustentação de núcleo rígido”. o corpo principal de núcleo compreende uma pluralidade de segmentos de núcleo divididos na direção circunferencial do pneu e sendo removíveis na direção radial. um núcleo cilíndrico inserido em um furo central do corpo principal de núcleo para impedir um movimento de cada um dos segmentos de núcleo para dentro na direção radial. um par de painéis laterais dispostos em ambos os lados do corpo principal de núcleo na direção do centro do eixo para impedir o movimento dos segmentos de núcleo na direção do centro do eixo. cada um dos painéis laterais é dotado, em sua superfície externa, de uma porção de eixo de suporte que se projeta para fora na direção do centro do eixo. a porção de eixo de suporte e o eixo de sustentação são conectados, removivelmente, com um meio de conexão tendo um sistema de bloqueio de esfera.patent summary for: "rigid core support structure". the core main body comprises a plurality of core segments divided in the circumferential direction of the tire and being removable in the radial direction. a cylindrical core inserted into a central hole of the core main body to prevent movement of each of the core segments inward in the radial direction. a pair of side panels arranged on either side of the core main body toward the center of the shaft to prevent movement of the core segments toward the center of the shaft. each side panel is provided on its outer surface with a support shaft portion which protrudes outwardly towards the center of the shaft. the support shaft portion and the support shaft are removably connected with a connecting means having a ball locking system.
