Abstract

"SISTEMA E MONTAGEM DE DIREçãO POR ENERGIA ELéTRICA". O mecanismo para remover a folga e o jogo presente entre um parafuso sem fim (8) e uma roda de rosca sem fim (10) na caixa de engrenagens de um sistema assistido que direciona a energia elétrica é divulgado. A engrenagem de rosca sem fim (8) é fornecida em uma árvore de saída (6) de um motor elétrico (4) e a roda é fornecida em uma outra árvore separada (9) (possivelmente na coluna de direção). A roda é fixa em relação a um alojamento (1) e a engrenagem de rosca sem fim é fixa em relação ao alojamento através de pelo menos uma primeira e uma segunda montagem de suporte (100, 200). A primeira montagem de suporte (100) é fornecida no final da árvore de saída (8), longe do motor (4) e compreende uma bucha excêntrica (101) que pode ser girada para ajustar a posição radial da árvore de saída e em conseq³ência da engrenagem de roda de rosca sem fim. O segundo suporte de montagem (200) permite o movimento angular da árvore de saída (6). O primeiro suporte de montagem (100) pode ser manualmente girado ou pode girar automaticamente sob uma força de mola para ajustar a quantidade de jogo.
