Abstract

Patente de Invenção para: <B>"MOLA DE L‰MINA PARA SUSPENSãO DE UM EIXO RìGIDO DE UM VEìCULO"<D>. A invenção refere-se a uma mola de lâmina (1) para suspensão de um eixo rígido (2) em um veículo. A mola é ligada em uma primeira extremidade (4) à estrutura de veículo (6), por dispositivo de junção que permitem movimento articulado ao redor de um eixo de articulação essencialmente paralelo ao eixo (2), e sendo ligada, na outra segunda extremidade (7) à estrutura por dispositivos de junção que permitem movimento articulado ao redor de um eixo de articulação essencialmente paralelo ao eixo (2) e deslocamento na direção longitudinal da mola, dita mola (1) sendo rigidamente ligada intermidiária em suas extremidades ao eixo (2) e também sendo feita com momentos transversais de inércia que variam na direção longitudinal da mola. A invenção é caracterizada pelo fato de que a dita mola (1) em uma primeira posição (19) estendendo-se entre a primeira extremidade (4) e a junção com o eixo (2), possui uma espessura que, a partir de um valor inicial na primeira extremidade (4) aumenta ao longo de uma curva parabólica para um valor máximo na junção com o eixo (2), e em uma segunda parte (20) estendendo-se entre a junção com o eixo (2) e a segunda extremidade (7) possui uma espessura que, a partir de um valor inicial, na segunda extremidade (7), aumenta ao longo de uma curva parabólica, para um valor máximo na junção com o eixo (2), o valor máximo na primeira parte (19) sendo maior do que ou essencialmente igual ao valor correspondente na segunda parte (20).
