Abstract
Description
Die Erfindung betrifft eine Betätigungsvorrichtung für eine Feststellbremse an Kraftfahrzeugen nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an actuating device for one Parking brake on motor vehicles according to the preamble of the claim 1.
Eine
Betätigungsvorrichtung
der gattungsgemäßen Art
ist aus der
Seit geraumer Zeit werden insbesondere der Handbremshebel und der Lagerbock als Gussteile ausgebildet, wobei insbesondere Leichtmetalllegierungen, wie Magnesiumlegierungen, zur Anwendung kommen, um Gewichtseinsparungen am Fahrzeug zu erzielen.since For some time, in particular, the handbrake lever and the bearing block formed as castings, in particular light metal alloys, Like magnesium alloys, they are used to reduce weight to achieve on the vehicle.
In der Praxis hat sich jedoch gezeigt, dass ein aus einem derartigen Guss hergestellter Lagerbock nicht immer allen denkbaren Beanspruchungen standhält.In However, practice has shown that one of such Cast bearing manufactured not always withstand all conceivable stresses.
So ist es Stand der Technik, denselben mit einem Anschlagpuffer zu versehen, der seinerseits die Null-Lage des Handbremshebels mitbestimmt. Im so genannten „Missbrauchstest", d. h. einem Test, bei dem sich beispielsweise der Fahrer in einer Null-Lage des Handbremshebels auf demselben abstützt, hat sich der Anschlagpuffer aus besagter Magnesiumlegierung verformt, welches unbedingt zu vermeiden ist. Hier setzt die nachfolgend beschriebene Erfindung an.So It is state of the art to the same with a stop buffer provided, which in turn determines the zero position of the handbrake lever. In the so-called "abuse test", ie a test, at For example, the driver in a zero position of the handbrake lever supported on the same, the stop buffer has deformed from said magnesium alloy, which is absolutely to be avoided. Here is the below described Invention.
Aufgabe der Erfindung ist es, eine Betätigungsvorrichtung der gattungsgemäßen Art zu schaffen, die ihrerseits hohen Beanspruchungen, insbesondere auch im Hinblick auf eine etwaige missbräuchliche Benutzung des Handbremshebels, standhält. Ferner ist es Aufgabe der Erfindung, das Gewicht sowie die Kosten der Betätigungsvorrichtung zu optimieren respektive zu reduzieren.task The invention is an actuator of the generic type to create, in turn, high demands, in particular also with regard to any improper use of the handbrake lever withstands. Further It is an object of the invention, the weight and the cost of the actuator to optimize respectively to reduce.
Erfindungsgemäß wird die Aufgabe durch eine Betätigungsvorrichtung für eine Feststellbremse an Kraftfahrzeugen mit einem in einem Lagerbock schwenkbeweglich gelagerten Handbremshebel, der seinerseits vermittels einer Arretiervorrichtung, bestehend aus einem Zahnsegment, in welches eine Sperrklinke kraft- und formschlüssig eingreift, in einer vorbestimmten Schwenkstellung fixierbar ist, dadurch gelöst, dass das Zahnsegment derart ausgebildet ist, dass der Handbremshebel in einer Null-Lage über die Sperrklinke am Zahnsegment abgestützt ist.According to the invention Task by an actuator for one Parking brake on motor vehicles with a pivotable in a bearing block mounted handbrake lever, which in turn by means of a locking device, consisting of a toothed segment into which a pawl force and positive fit engages, can be fixed in a predetermined pivot position, solved by that the toothed segment is designed such that the handbrake lever in a zero position about the pawl is supported on the toothed segment.
Durch diese Maßnahme kann in besonders vorteilhafter Weise auf einen Anschlagpuffer am Lagerbock verzichtet werden, welches zu Material- und demgemäß Gewichts- sowie zu Kosteneinsparungen führt.By This measure can in a particularly advantageous manner to a stop buffer on Lagerbock be waived, which is material and thus weight and cost savings.
Das Zahnsegment weist dabei in besagter Null-Lage eine Stützaufnahme für die Sperrklinke auf, wobei die Stützaufnahme durch eine besondere Gestaltung der Außenkontur des Zahnsegments oder durch einen weiteren Segment-Zahn gebildet sein kann.The In this case, the toothed segment has a support receptacle in said zero position for the Pawl on, with the support receptacle by a special design of the outer contour of the toothed segment or may be formed by another segment tooth.
Aufgrund der Tatsache, dass Sperrklinke und Zahnsegment herkömmlich aus Stahlblech gefertigt sind, können durch dieselben etwaige überhöhte Kräfte aus missbräuchlicher Benutzung des Handbremshebels wirkungsvoll und ohne Schäden an der Betätigungsvorrichtung verursachend aufgenommen werden.by virtue of the fact that pawl and toothed segment are made conventionally Steel sheet are made, can through them any excessive forces abusive Using the hand brake lever effectively and without damage to the actuator be causally recorded.
Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The Invention is described below with reference to an illustrated in the drawings embodiment explained in more detail. It demonstrate:
