Abstract

"CONUNTO DE DIREçãO PARA VIRAR RODAS DIRECIONáVEIS DE UM VEìCULO EM RESPOSTA à ROTAçãO DE UM VOLANTE DE DIREçãO DE UM VEìCULO". Um conjunto de direção (10) para virar rodas direcionáveis de um veículo em resposta à rotação de um volante de direção (12) inclui um pinhão (30). Um membro de diração (14) é axialmente movível para efetuar movimento de virada das rodas direcionáveis do veículo. O membro de direção (14) apresenta uma porção de cremalheira (34) para engatar com o pinhão (30) e uma porção de fuso externamente roscada (38). Um porta esferas (140) se estende ao redor da porção de fuso (38) do membro de direção (14) e apresenta uma rosca interna (144). Uma pluralidade de esferas (200) está disposta entre a rosca interna (144) sobre o porta esferas (140) e a rosca (40) sobre o membro de direção (14) para transmitir força entre o porta esferas e porção de fuso (38) do membro de direção. Um motor elétrico (50) inclui um rotor (132) acionavelmente conectado no porta esferas (140) e em um estator (70). O estator (70) quando energizado efetua rotação do rotor (132) e, por conseguinte, rotação do porta esferas (140). A montagem de direção inclui um membro plástico moldado de uma peça (60) possuindo uma primeira porção axial (62) disposta adjacente ao pinhão (30), uma segunda porção axial (66) encapsulando e suportando o núcleo do estator (72) e os enrolamentos do estator (82), e uma terceira porção axial (110) suportando o porta esferas (140) para rotação com o rotor (132).
