Abstract
mola helicoidal a presente invenção trata de uma mola helicoidal que tem uma secção efetiva (11) que funciona como uma mola, quando uma carga for aplicada em uma direção eixo geométrico de espira, as seções de volta de extremidade (12) que são formadas em ambas as extremidades da seção efetiva (11), e seções ascendentes (13) que se formam entre a seção efetiva (11) e as seções de volta de extremidade (12), em que as seções ascendentes (13) são formadas de tal modo que, quando 01 representa um ângulo de passo das seções ascendentes (13) e 02 representa um ângulo de passo da seção efetiva (11. ângulo de passo 01 (maior) ângulo de passo 02 é verdadeiro em pelo menos uma das seções ascendentes (13).
