Abstract
Description
Die Erfindung betrifft eine Betätigungsvorrichtung für eine Feststellbremse mit einem an einem Lagerbock schwenkbar gelagerten Handbremshebel, welcher mittels einer Festsetzeinrichtung in einer vorgegebenen Schwenkstellung fixierbar ist. Die Festsetzeinrichtung weist ein Zahnsegment mit einer eine Mehrzahl von Zähnen aufweisenden Verzahnung sowie eine mit diesem Zahnsegment zum Festsetzen der Schwenkstellung des Handbremshebels zusammenwirkende Sperrklinke auf.The The invention relates to an actuating device for one Parking brake with a pivotally mounted on a bearing block Hand brake lever, which by means of a fixing device in a predetermined pivot position is fixed. The fixing device includes a sector gear having a plurality of teeth Gearing and one with this toothed segment for setting the Swivel position of the handbrake lever cooperating pawl on.
Eine

ist aus der
Wird der Handbremshebel zur Betätigung der Feststellbremse aus seiner Ruhelage, d. h. aus seinem abgelegten Zustand beispielsweise durch ein Nachobenziehen bewegt, so rastet die Sperrklinke nach einem definierten Weg in die erste Zahnlücke bzw. das erste Tal in der Verzahnung des Zahnsegments ein. Dabei ist durch eine entsprechende konstruktive Gestaltung des Zahnsegments der Betätigungsweg zwischen der Position des Handbremshebels bei gelöster bzw. nichtbetätigter Feststellbremse und der ersten Zahnlücke des Zahnsegments größer als der Betätigungsweg von einer Zahnlücke des Zahnsegments in die nächste Zahnlücke des Zahnsegments. Auf diese Weise wird ein sicheres Auslösen des Bremslichtschalters vor Erreichen der ersten Zahnlücke des Zahnsegments und dem ersten Arretieren der Sperrklinke in der Verzahnung gewährleistet.Becomes the handbrake lever for actuating the Parking brake from its rest position, d. H. from his filed State, for example, moved by a Nachobenziehen so snaps the pawl after a defined path in the first tooth gap or the first valley in the teeth of the dental segment. It is by a corresponding structural design of the toothed segment the actuation path between the position of the hand brake lever when dissolved or not actuated Parking brake and the first tooth gap of the tooth segment greater than the actuation path from a tooth gap of the tooth segment in the next gap of the tooth segment. In this way, a safe triggering of the Brake light switch before reaching the first tooth gap of the Tooth segments and the first locking of the pawl in the toothing guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, eine Betätigungsvorrichtung für eine Feststellbremse mit einem schwenkbar gelagerten Handbremshebel derart weiterzubilden, dass die mechanische Beanspruchung der Verzahnung der aus Sperrklinke und Zahnsegment bestehenden Festsetzeinrichtung reduziert wird.Of the Invention is based on the object, an actuating device for a parking brake to develop a pivotally mounted handbrake lever in such a way that the mechanical stress of the teeth of the pawl and toothed segment existing fixing device is reduced.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Indem die Sperrklinke wenigstens zwei Zähne hat, die bei Betätigung der Feststellbremse beim Festsetzen des Handbremshebels in einer verschwenkten Stellung mit der Verzahnung des Zahnsegments in Eingriff stehen, werden die aus dem Feststellbremssystem auf die Verzahnung der aus Sperrklinke und Zahnsegment bestehenden Festsetzeinrichtung wirkenden Kräfte gleichmäßiger verteilt und so die auf die einzelnen Zähne wirkende Beanspruchung wesentlich reduziert. Auf diese Weise ist es möglich, statt der bisher für Zahnsegment und Sperrklinke verwendeten hochwertigen Stahlwerkstoffe auch andere, kostengünstigere Werkstoffe mit geringerer Festigkeit zu verwenden. Dies führt zu einer kostengünstigeren und gegebenenfalls auch leichteren Ausführung der Betätigungsvorrichtung.These The object is solved by the features of claim 1. By doing the pawl has at least two teeth that upon actuation of the Parking brake when setting the handbrake lever in a pivoted Position with the teeth of the toothed segment are engaged, are from the parking brake system on the gearing of Pawl and toothed segment existing fixing device acting personnel evenly distributed and so on the individual teeth significantly reduces the effective stress. That way is it is possible instead of previously for Tooth segment and pawl used high quality steel materials also other, cheaper To use materials with lower strength. This leads to a cheaper and possibly also lighter version of the actuator.
Vorteilhafte Weiterbildungen und Verbesserungen der Erfindung sind in den untergeordneten Ansprüchen angegeben.advantageous Further developments and improvements of the invention are specified in the subordinate claims.
Besonders vorteilhaft ist es, wenn das Zahnsegment eine Kulissenbahn und die Sperrklinke ein Führungselement aufweist, wobei beim Verschwenken des Handbremshebels das Führungselement der Sperrklinke mit der Kulissenbahn des Zahnsegments zusammenwirkt. Auf diese Weise kann bei geeigneter Auslegung von Kulissenbahn und Führungselement auf einfache Art und Weise gewährleistet werden, dass die Sperrklinke beim Festsetzen des Handbremshebels stets mit allen ihren Zähnen im Eingriff mit der Verzahnung des Zahnsegments ist. Dadurch wird sichergestellt, dass nicht nur beispielsweise lediglich ein Zahn der mehrere Zähne aufweisenden Sperrklinke mit der Verzahnung des Zahnsegments in Überdeckung ist.Especially It is advantageous if the toothed segment a slide track and the Pawl a guide element has, wherein upon pivoting of the handbrake lever, the guide element the pawl cooperates with the slide track of the toothed segment. In this way, with a suitable design of slide track and guide element ensured in a simple manner Be sure that the pawl when setting the handbrake lever always with all her teeth in engagement with the toothing of the toothed segment. This will ensured that not only, for example, just a tooth the several teeth having pawl with the toothing of the toothed segment in coverage is.
Aus dem gleichen Grund ist ebenfalls von Vorteil, wenn die Sperrklinke eine Kulissenbahn und das Zahnsegment ein Führungselement aufweisen, wobei beim Verschwenken des Handbremshebels das Führungselement des Zahnsegments mit der Kulissenbahn der Sperrklinke zusammenwirkt.Out The same reason is also beneficial when the pawl a slide track and the toothed segment have a guide element, wherein when pivoting the handbrake lever, the guide element of the toothed segment interacts with the slide track of the pawl.
Für eine einfache und kostengünstige Herstellung von Sperrklinke und Zahnsegment ist es von Vorteil, wenn zumindest der die Verzahnung aufweisende Teil des Zahnsegments und/oder der Sperrklinke aus einem Kunststoff ausgebildet ist oder das Zahnsegment und/oder die Sperrklinke selbst vollständig aus einem geeigneten Kunststoff ausgebildet ist.For a simple and cost-effective Production of pawl and toothed segment, it is advantageous if at least the toothed portion of the toothed segment and / or the pawl is formed of a plastic or the sector gear and / or the pawl itself completely off a suitable plastic is formed.
