Title
(DE) BETÄTIGUNGSEINRICHTUNG FÜR PARKSPERRE
(EN) CONTROL ELEMENT FOR A PARKING LOCK
(FR) DISPOSITIF D'ACTIONNEMENT POUR FREIN DE STATIONNEMENT
Abstract
(DE)
Die Erfindung betrifft eine Parksperren-Betätigungseinrichtung (1) insbesondere für ein Automatikgetriebe. Die Betätigungseinrichtung (1) umfasst eine mit der Parksperrenklinke gekoppelte Stelleinrichtung (6), sowie eine auf die Stelleinrichtung (6) wirkende Halteeinrichtung (8, 10, 11, 12) zur Sicherung der Parksperrenklinke in der ausgerückten Stellung. Erfindungsgemäß zeichnet sich die Verbindungseinrichtung dadurch aus, dass die Halteeinrichtung (8, 10, 11, 12) einen mit der Stelleinrichtung (6) verbundenen Sperrschieber (8) sowie einen Sperraktuator (11) mit einem aktuatorisch breitenveränderlichen Schieberspalt (10) umfasst, wobei der Sperrschieber (8) - bei geöffnetem Schieberspalt (10) - unter Freigabe der Stelleinrichtung (6) in den Schieberspalt (10) einfahren kann. Die erfindungsgemäße Verbindungseinrichtung führt zu einer Reduzierung des konstruktiven Aufwands und der damit verbundenen Kosten. Gleichzeitig ist die Betätigungseinrichtung vergleichsweise unempfindlich gegenüber Fertigungstoleranzen, Beschleunigungskräften, Vibrationen sowie Temperaturbelastungen. Es werden mit geringer Hilfsenergie hohe Haltekräfte zur Sicherung der Parksperrenklinke erzielt. Eine Notbetätigung kann auf einfache Weise integriert werden.
(EN)
The invention relates to a parking lock control element (1), particularly for an automatic transmission. The control element (1) has an adjusting device (6) which is coupled to the parking lock pawl, and a  fixture device (8, 10, 11, 12) which works with the adjusting device (6) to secure the parking lock pawl in the disengaged position. According to the invention, the connecting device is characterized is that the fixture device (8, 10, 11, 12) has a ratchet slide (8) connected to the adjusting device (6), and a locking actuator (11) having a slide gap (10), the width of said slide gap being modified in an actuating manner, wherein the ratchet slide (8) can move into the slide gap (10) – when the slide gap is open (10) – releasing the adjusting device (6). The connecting device according to the invention leads to a reduction in construction requirements and related costs. At the same time, the control element is comparatively robust with respect to manufacturing tolerances, acceleration forces, vibrations, and temperature loads. With minimal auxiliary energy, high fixing forces can be achieved to secure the parking lock pawl. An emergency activation can also be integrated in a simple manner.
(FR)
L'invention concerne un dispositif d'actionnement de frein de stationnement (1) notamment pour une transmission automatique. Le dispositif d'actionnement (1) comprend un dispositif de commande (6) accouplé au cliquet du frein de stationnement, ainsi qu'un dispositif de retenue (8, 10, 11, 12) agissant sur le dispositif de commande (6) pour la fixation du cliquet de frein de stationnement dans la position débrayée. Conformément à l'invention, le dispositif de connexion est caractérisé en ce que le dispositif de  retenue (8, 10, 11, 12) comprend un coulisseau de blocage (8) connecté au dispositif de commande (6) ainsi qu'un actionneur de blocage (11) avec une fente de coulisseau (10) de largeur variable sous l'effet de l'actionneur. Le coulisseau de blocage (8), lorsque la fente de coulisseau (10) est ouverte, peut entrer dans la fente de coulisseau (10) en libérant le dispositif de commande (6). Le dispositif de connexion selon l'invention permet une réduction de la complexité de la construction et donc des frais associés. En même temps, le dispositif d'actionnement est relativement insensible aux tolérances de fabrication, aux forces d'accélération, aux vibrations et aux contraintes de température. On obtient, avec une faible énergie auxiliaire, de grandes forces de maintien pour fixer le cliquet du frein de stationnement. Un actionnement d'urgence peut être intégré de manière simple.
