Title
(EN) GEAR SHIFT MECHANISM FOR PREVENTING UNINTENTIONAL GEAR DISENGAGEMENT IN A VEHICLE GEARBOX
(FR) MÉCANISME DE CHANGEMENT DE VITESSE DESTINÉ À ÉVITER UN DÉBRAYAGE DE L'ENGRENAGE INVOLONTAIRE DANS UNE BOÎTE DE VITESSES D'UN VÉHICULE
Abstract
(EN)
Gear shift mechanism for preventing unintentional gear disengagement, comprising a gearbox lever (7) , mounted for pivoting around a first pivot point (9) between two end positions. A first end (10) of a bar (4) is rotatably fixed to the gearbox lever (7) at a first distance from said first pivot point (9) of the gearbox lever (7) . A second end (11) of said bar (4) is rotatably fixed to a main lever (1) at a second distance from a main lever pivot point (3) . A first end (12) of a spring means (5) is rotatably fixed to the main lever in a pivot point (14) at a third distance from said main lever pivot point. A second end (13) of said spring means (5) is rotatably fixed to a second pivot point (6) at a fixed position relative to said first pivot point (9) and said main lever pivot point (3) .

L'invention concerne un mécanisme destiné à éviter un débrayage de l'engrenage involontaire, comprenant un levier de boîte de vitesses (7), monté de sorte à pivoter autour d'un premier point de pivotement (9) entre deux positions terminales. Une première extrémité (10) d'une barre (4) est fixée de façon rotative au levier de boîte de vitesses (7) à une première distance dudit premier point de pivotement (9) du levier de boîte de vitesses (7). Une seconde extrémité (11) de ladite barre (4) est fixée de façon rotative à un levier principal (1) à une deuxième distance du point de pivotement du levier principal (3). Une première extrémité (12) d'un moyen à ressort (5) est fixée de façon rotative au levier principal au niveau d'un point de pivotement (14) à une troisième distance dudit point de pivotement du levier principal. Une seconde extrémité (13) dudit moyen à ressort (5) est fixée de façon rotative au niveau d'un second point de pivotement (6) à une position fixe par rapport audit premier point de pivotement (9) et audit point de pivotement du levier principal (3).
