Abstract[English]
The present invention relates to a steering column assembly (20) comprising: - a rotary steering shaft (26) of longitudinal axis (AX); - a structural element (24) blocked against rotation about the longitudinal axis; - an angular-blocking mechanism (40) ensuring cooperation between the structural element and the steering shaft in order to limit a rotation of the steering shaft, comprising: - first and second internal threads (52, 54), of opposite orientations and constrained to rotate as one with the steering shaft; - a first and a second nut (44, 46) each comprising an external thread (60, 62) cooperating with a corresponding one of the internal threads; - means forming a guideway between the nuts and the steering shaft; - means for limiting the longitudinal travel of the nuts.[French]
La présente invention a pour objet un ensemble de colonne de direction (20), comportant : - un arbre de direction (26) rotatif d'axe longitudinal (AX); - un élément de structure (24) bloqué en rotation autour de l'axe longitudinal; - un mécanisme de blocage angulaire (40) assurant une coopération entre l'élément de structure et l'arbre de direction pour borner une rotation de l'arbre de direction, comprenant : - un premier et un deuxième filetages intérieurs (52, 54), d'orientations opposées et solidaires en rotation de l'arbre de direction; - un premier et un deuxième écrous (44, 46) comportant chacun un filetage extérieur (60, 62) coopérant avec un des filetages intérieurs correspondant; - des moyens formant glissière entre les écrous et l'arbre de direction; - des moyens de limitation de course longitudinale des écrous.
