Abstract

L'invention concerne une unité de sélection de vitesse (102) destinée à une boîte de vitesses automatique (104) d'un véhicule (100), comprenant un cadre (200), un levier de vitesses (108), un coulisseau à câble (202) et un connecteur (204). Le cadre (200) comprend une coulisse (206). Le cadre (206) comporte un canal Automatique (208) orienté dans une direction longitudinale et un canal Impulsions (210) adjacent orienté dans la direction longitudinale. Le canal Automatique (208) et le canal Impulsions (210) sont reliés entre eux par un canal de liaison orienté dans une direction transversale (212). Le levier de vitesses (108) est guidé dans la coulisse (206) et monté de façon pivotante dans le cadre (200). Le coulisseau de câble (202) est monté dans le cadre (200) de façon mobile dans la direction longitudinale. Le coulisseau à câble (202) est accouplé au levier de vitesses (108) dans la direction longitudinale par le biais d'un premier moyen d'accouplement (214) amovible lorsque le levier de vitesses (108) est placé dans le canal Automatique (208). Le connecteur (204) est accouplé dans la direction longitudinale au coulisseau de câble (204) par le biais d'un deuxième moyen d'accouplement (216) et dans la direction transversale au levier de vitesses (108) par le biais d'un troisième moyen d'accouplement (218). Le connecteur (204) est fixé dans la direction longitudinale au cadre (200) par le biais d'un quatrième moyen d'accouplement amovible (220) lorsque le levier de vitesses (108) est placé dans le canal Impulsions (210).
