Abstract

L’invention a pour objet un verrou de parking pour une transmission d’un véhicule automobile, comportant un dispositif mobile d’actionnement (24) disposant d’une position de blocage d’une roue crantée liée aux roues du véhicule, un ressort d’actionnement (16) qui tend à maintenir ce dispositif dans sa position de blocage, et un vérin hydraulique (14) prévu pour actionner le dispositif (24) vers une position de déblocage de la roue crantée, caractérisé en ce qu’il comporte un doigt mobile de retenue (32) pouvant retenir le dispositif d’actionnement (24) dans sa position de déblocage, comprenant un ressort de rappel (36) qui tend à déplacer le doigt (32) vers une position d’absence de retenue de ce dispositif d’actionnement (24). Figure 3.The invention relates to a parking lock for a transmission of a motor vehicle, comprising a movable actuating device (24) having a locking position of a toothed wheel connected to the wheels of the vehicle, a spring for 'actuation (16) which tends to maintain this device in its blocking position, and a hydraulic cylinder (14) provided to actuate the device (24) towards an unlocking position of the toothed wheel, characterized in that it comprises a movable retaining finger (32) capable of retaining the actuator (24) in its unlocked position, comprising a return spring (36) which tends to move the finger (32) towards a position of no retention of this actuating device (24). Figure 3.
