Abstract

"GUIA DE CREMALHEIRA". Uma guia de cremalheira (150) transmite uma força de précarga de uma mola (36) para uma cremalheira de direção em um mecanismo de direção de cremalheira e pinhão (12). A guia de cremalheira (150 é uma estrutura cilíndrica tendo uma superfície de parede periférica externa (154) com um contorno cilíndrico complementar a uma superfície interna cilíndrica (14) do cárter (12), e adicionalmente tendo uma superfície de parede extrema (158) com um contorno cilíndrico complementar a uma superfície cilíndrica (56) da cremalheira (14). A estrutura cilíndrica (150) tem partes recíprocas móveis que incluem segmentos circunferencialmente separados (170,172), cada um dos quais define uma respectiva parte segmentar da superfície de parede periférica externa (154). As partes reciprocamente móveis da estrutura cilíndrica (150) adicionalmente incluem uma nervura flexível (190) que interconecta e suporta um par adjacente de segmentos (170,172) para deslocamento mútuo.
