Title (EN) SELECTOR LEVER LOCK DEVICE FOR AN AUTOMATIC TRANSMISSION IN A MOTOR VEHICLE
(FR) DISPOSITIF DE VERROUILLAGE DE LEVIER DE SELECTEUR DESTINE A UNE TRANSMISSION AUTOMATIQUE D'AUTOMOBILE
Abstract:
(EN) A selector lever lock device for an automatic transmission in a motor vehicle includes a tilt lever (36) pivotally attached to an upright detent plate (24) for pivotal movement about a pivot axis (38) into a lock or release position to allow or prevent free movement of a detent pin carried by the selector lever (12). The tilt lever (36) is provided with first (40) and second arm portions (42) each extending from the pivot axis (38) in different directions, the first arm portion (40) having at its distal end a claw (44) which serves to keep the detent pin (22) from moving downwards. Remaining engaged with the second arm portion (42) of the tilt lever is a solenoid mechanism that responds to the depression of the brake pedal (10) for causing the tilt lever (36) to rotate into the release position to thereby allow the detent pin (22) to move freely so that the selector lever (12) can be shifted to non-parking positions. A compression spring (60) is retained between the solenoid mechanism and the second arm portion (42) to bias the tilt lever (36) into the lock position.
(FR) Ce dispositif de verrouillage de levier sélecteur, destiné à une transmission automatique d'automobile, comprend un levier inclinable (36) fixé de façon à pivoter sur une plaque crantée verticale (24), autour d'un axe de pivotement (38), vers une position de verrouillage ou de libération, ce qui doit permettre ou prévenir le libre déplacement d'une goupille d'arrêt portée par le levier sélecteur (12). Ce levier inclinable (36) comprend deux bras (40, 42) divergeant depuis l'axe de pivotement (38), le premier (40) présentant à son extrémité distale une griffe (44) empêchant la goupille d'arrêt (22) de se déplacer vers le bas. Restant en prise avec le deuxième bras (42) du levier inclinable (36), un mécanisme à solénoïde réagit à l'enfoncement de la pédale de frein (10) pour faire pivoter ce levier (36) et le mettre en position de libération, ce qu permet à la goupille d'arrêt (22) de se déplacer librement afin que le levier sélecteur (12) puisse passer à d'autres positions que celles de parcage. Un ressort de compression (60) est disposé entre le mécanisme à solénoïde et le deuxième bras pour comprimer le levier inclinable (36) et le mettre en position de verrouillage.
