Abstract

Dispositif de blocage mécanique (1) d'un arbre de transmission (10) d'un véhicule automobile comprenant au moins : - une roue de parking (5) solidaire de l'arbre de transmission, - un levier de blocage de la roue (5) pivotant autour d'un axe entre au moins une position de blocage et une position de libération de la roue, - une tringle (3) longitudinale de commande présentant une extrémité liée avec jeu à un plateau de commande (2) du dispositif de blocage mécanique, - un poussoir coulissant sur la tringle (3) et sollicité par un ressort contre une butée de guidage arrêtant la tringle et le poussoir vers le haut, caractérisé en ce que le dispositif comporte des moyens limiteurs de débattement (2c, 11) contraignant l'extrémité libre de la tringle (3) contre la butée par appui sur le plateau de commande (2), tant que le dispositif de blocage mécanique n'est pas actionné.Mechanical locking device (1) of a drive shaft (10) of a motor vehicle comprising at least: - a parking wheel (5) integral with the drive shaft, - a wheel locking lever ( 5) pivoting about an axis between at least one locking position and a wheel release position, - a longitudinal control rod (3) having one end linked with play to a control plate (2) of the mechanical locking, - a pusher sliding on the rod (3) and urged by a spring against a guide stop stopping the rod and the pusher upwards, characterized in that the device comprises means limiting travel (2c, 11) forcing the free end of the rod (3) against the stop by pressing on the control plate (2), as long as the mechanical locking device is not actuated.
