Abstract

é divulgado um mecanismo de ração de compressão variável (5), no qual um eixo de controle (10) é girado e acionado por um motor elétrico (21) através de um redutor de engrenagem de onda (22). o redutor de engrenagem de onda (22) inclui: um primeiro membro de engrenagem interna (31); um membro de engrenagem externa (32) disposto concentricamente no interior do membro de engrenagem interna (31); um gerador de ondas (33) disposto no interior do membro de engrenagem externa (32); e um segundo membro de engrenagem interna (34), em que uma razão entre o número de dentes de uma porção de engrenagem fixa (35) do primeiro membro de engrenagem interna (31) para o número de dentes de uma primeira porção de engrenagem (37) do membro de engrenagem externa (32) é definida menor que uma razão do número de dentes de uma porção de engrenagem do lado de fora (42) do segundo membro de engrenagem interna (34) para o número de dentes de uma segunda porção de engrenagem (38) do membro de engrenagem externa (32). assim, a profundidade do dente de engrenagem da porção de engrenagem do lado de fora (42) do segundo membro de engrenagem interna (34) se torna relativamente grande, de modo a atingir um maior torque de catraca e evitar a catraca.
