Abstract

ABSORVEDOR DE CHOQUE HIDRÁULICO. Em um membro de atrito (22), uma seção de base (92) é constituído por uma seção de fundo (101) e uma seção de tubo (102). A seção de fundo (101) tem uma forma de disco furado e a seção de tubo (102) tem uma forma cilíndrica que se estende a partir de um lado circunferencial exterior de seção de fundo (101) na direção axial. Uma seção de borracha elástica (91) tem uma seção de diâmetro interior mínimo (137), seções que expandem em diâmetro (138, 139) que são colocadas em cada lado na direção axial da seção de diâmetro interior mínimo (137). Uma superfície que adere à seção de tubo (126) é instalada no lado circunferencial exterior de uma seção de tubo (102). Uma seção recorte (151) é no mínimo parcialmente formada em uma superfície que adere à seção de fundo (128) fixada à seção de fundo (101) e ao lado de seção de tubo (102) de uma superfície aberta em um lado oposto na direção axial, e uma seção mais profunda (155) de seção de recorte (151) é mais rasa do que uma posição na direção axial da seção de diâmetro interior mínimo (137).
