Abstract

L'invention concerne un dispositif de blocage (1) d'une transmission comprenant un élément boîtier (2) et un élément de transmission (3) monté de manière mobile par rapport à l'élément boîtier (2). Une tige de blocage (4) est agencée dans l'élément boîtier (2) dans un alésage (5) de l'élément boîtier (2), la tige de blocage (4) pouvant être introduite dans un évidement (6) ménagé dans l'élément de transmission (3) pour empêcher dans une position verrouillée que l'élément de transmission (3) ne puisse se déplacer par rapport à l'élément boîtier (2). Des moyens d'encliquetage (7) permettent d'immobiliser axialement la tige de blocage (4) dans la position verrouillée (a), les moyens d'encliquetage (7) comportant une coulisse (8) qui est agencée directement ou indirectement dans l'élément boîtier (2) et qui présente une section (9) s'étendant dans la direction axiale (a) et une section (10) s'étendant au moins par endroits transversalement à la direction axiale (a). Un élément d'actionnement (11) assurant le déplacement axial de la tige de blocage (4) est agencé de manière à pouvoir tourner autour de l'axe (a) de la tige de blocage (4), et un élément d'encliquetage (12) glissant dans la coulisse (8) est agencé directement ou indirectement sur l'élément d'actionnement (11).
