Abstract

[L’invention concerne un frein de stationnement (1) pour une transmission comportant un dispositif de verrouillage (2), lequel comprend un élément d’actionnement (3) pouvant être actionné et un élément de réglage (4) déplaçable entre une position sortie et une position rentrée, réalisé de telle sorte que, par actionnement répété de l’élément d’actionnement (3), l’élément de réglage (4) est déplacé alternativement entre la position rentrée et la position sortie par le biais d’un mécanisme d’accouplement (5). En outre, le frein de stationnement (1) comporte un arbre à came (6) pouvant tourner autour d’un axe de rotation (D), arbre sur lequel est disposée une came (7) reliée par entraînement au dispositif de verrouillage (2), adaptée au dispositif de verrouillage (2) de telle sorte qu’en cas d’arbre à came (7) tournant, l’élément d’actionnement (3) est actionné par la came (7). De plus, le frein de stationnement (1) comporte une roue à cliquet (8) pouvant tourner autour d’un axe de roue (R) et comportant un cliquet de verrouillage (9), lequel est déplaçable entre une position d’entrée en prise dans laquelle il bloque une rotation de la roue à cliquet (8) autour de l’axe de roue (R) et une position de libération dans laquelle le blocage de la roue à cliquet (8) est supprimé. À cet effet, l’élément de réglage (3) est réalisé pour le déplacement du cliquet de verrouillage (9) entre les positions d’entrée en prise et de libération.] Figure pour l’abrégé : Fig 1
