Abstract

L'invention concerne un différentiel du type à blocage mécanique. Le différentiel actionne un câble (15) en tirant pour déplacer une fourchette (3) le long d'une glissière de guidage (7) dans le sens de la traction et un ressort (8) est comprimé pendant ce mouvement. Ainsi une seconde roue dentée (2) est amenée à s'engrener avec une première roue dentée (1), de telle sorte qu'un demi-essieu (17) de différentiel est rattaché rigidement au différentiel et de ce fait le différentiel est bloqué.
