Description

Anordnung eines Fußhebels für Kraftfahrzeuge, insbesondere des Kupplungshebels für Personenkraftwagen Die Erfindung bezieht sich auf eine Anordnung eines Fußhebels für Kraftfahrzeuge, insbesondere des Kupplungshebels für Personenkraftwagen, wobei das Betätigen des Fußhebels im ersten Teil des Betätigungshubes gegen die Kraft einer einerseits auf den Fußhebel einwirkenden und andererseits ortsfest gelagerten Rückholfeder erfolgt, während nach einem bestimmten Hub ein Drehmomentrichtungswechsel stattlindet, wodurch auf den Fußhebel ein die Betätigung desselben unterstützendes Moment einwirkt.Arrangement of a pedal for motor vehicles, in particular the clutch lever for passenger cars The invention relates to an arrangement of a foot lever for motor vehicles, in particular the clutch lever for passenger cars, with the actuation of the foot lever in the first part of the actuation stroke against the force one acting on the one hand on the foot lever and on the other hand fixedly mounted Return spring takes place while a torque direction change after a certain stroke takes place, whereby the operation of the same supporting the foot lever Moment acts.

Um eine derartige Wirkung zu erreichen, ist bereits eine Anordnung eines Fußhebels bekannt, bei der am Fußhebel ein zusätzliches Zwischenglied angelenkt ist, an dessen anderem Ende eine Spiralfeder angreift, die wiederum an einem ortsfesten Karosserieteil befestigt ist. Hierbei durchläuft die Spiralfeder mit zunehmendem Hub des Fußhebels eine Totpunktstellung und übt nach überschreiten des Totpunktes ein zunehmendes, in Betätigungsrichtung des Fußhebels wirkendes Drehmoment auf den Fußhebel aus.In order to achieve such an effect, there is already an arrangement a foot lever is known in which an additional intermediate link is articulated on the foot lever is, at the other end of which engages a spiral spring, which in turn is attached to a stationary one Body part is attached. The spiral spring runs through with increasing Stroke of the foot lever a dead center position and exercises after passing the dead center an increasing torque acting in the direction of actuation of the foot lever on the Pedal off.

Der Erfindung liegt die Aufgabe zugrunde, eine derartige Anordnung eines Fußhebels mit möglichst geringem Aufwand und geringem Platzbedarf herzustellen und schlägt hierzu vor, daß der Drehmomentrichtungswechsel ohne zusätzliche Führungsglieder lediglich durch eine schraubenförmig gewundene Biegefeder bewirkt wird, deren Mittelstück unmittelbar mit dem Fußhebel in Verbindung steht und deren beide Enden ortsfest gelagert sind.The invention is based on the object of such an arrangement to produce a foot lever with the least possible effort and space requirement and suggests that the torque direction change without additional guide links is caused only by a helically wound spiral spring, the center piece is directly connected to the foot lever and both ends of which are stationary are stored.

Ferner wird zur Lösung der erfindungsgemäßen Aufgabe vorgeschlagen, daß die Biegefeder zwischen den zur Lagerung des Fußhebels dienenden Fußhebelböcken angeordnet ist und ihre beiden Enden in den Fußhebelböcken gelagert sind, wobei das Mittelstück der Biegefeder in an sich bekannter Weise an dem freien Ende des Fußhebels angreift.It is also proposed to solve the problem according to the invention, that the spiral spring between the foot lever brackets serving to support the foot lever is arranged and both ends are mounted in the foot lever brackets, wherein the center piece of the spiral spring in a known manner at the free end of the Attacks the foot lever.

Die Erfindung zeichnet sich gegenüber den bekannten Fußhebelanordnungen besonders durch ihren konstruktiv einfachen und damit keinen Funktionsstörungen unterworfenen Aufbau aus, der mit äußerst ,geringem Aufwand an Material, Arbeitszeit usw. herzustellen sowie praktisch wartungsfrei ist und sich auch nachträglich ohne weiteres einbauen läßt. Ein vieiterer wesentlicher Vorteil der Erfindung gegenüber den bekannten Anordnungen ist in der räumlich gedrängten Bauart zu sehen, da die Biegefeder zwischen den Fußhebelböcken eingebaut ist und somit keinen zusätzlichen Bauraum beansprucht.The invention is distinguished from the known foot lever arrangements especially because of their simple construction and therefore no malfunctions subject to construction from, with extremely, little expenditure on material, labor etc. and is practically maintenance-free and can also be retrofitted without can be installed further. Another major advantage of the invention the known arrangements can be seen in the compact design, since the A spiral spring is installed between the foot lever brackets and therefore no additional ones Requires space.

Ferner ermöglicht die erfindungsgemäße Anordnung eine vorteilhafte Fertigmontage am Fußhebellagerbock ohne Einstellschwierigkeiten, da die genaue Zuordnung der Lagerstellen der Feder bzw. des Fußhebels zueinander, beispielsweise in einem Stanzwerkzeug, sichergestellt ist.Furthermore, the arrangement according to the invention enables an advantageous Final assembly on the foot lever bearing block without adjustment difficulties, as the exact assignment the bearing points of the spring or the foot lever to each other, for example in one Punching tool, is ensured.

In den Zeichnungen ist die Anordnung nach der Erfindung an Hand eines Ausführungsbeispieles dargestellt, und zwar zeigen die F i g. 1 und 2 jeweils einen Teil des Fußhebels mit seiner Lagerung in verschiedenen Ansichten.In the drawings, the arrangement according to the invention is shown on the basis of an exemplary embodiment, namely the F i g. 1 and 2 each part of the foot lever with its storage in different views.

Der Fußhebel 1, z. B. ein Kupplungshebel, ist am Fußhebellagerbock, d. h. zwischen den Fußhebelböcken 2 und 3 schwenkbar gelagert. Das freie Ende des Fußhebels 1 greift in das Mittelstück 4 einer schraubenförmig gewundenen Biegefeder 5, deren Windungen zu beiden Seiten des Fußhebels 1 angeordnet sind, wobei die Enden 6 und 7 der Biegefeder 5 in den Fußhebelböcken 2 und 3 gelagert sind. In F i g. 1. zeigt die stark ausgezogene Darstellung die Normallage des Fußhebels. Durch Betätigen des Fußhebels 1 in Pfeilrichtung erfolgt nach Überschreiten einer Totpunktstellung der Drehmomentrichtungswechsel der Biegefeder 5 und der Fußhebel 1 gelangt in seine Endstellung. Dies würde bei Anwendung der Erfindung auf eine Kupplung dem ausgerückten Zustand der Kupplung (strich-punktiert gezeichnet) entsprechen.The foot lever 1, z. B. a clutch lever is on the foot lever bracket, d. H. mounted pivotably between the foot lever brackets 2 and 3. The free end of the foot lever 1 engages in the center piece 4 of a helically wound spiral spring 5, the turns of which are arranged on both sides of the foot lever 1 , the ends 6 and 7 of the spiral spring 5 being mounted in the foot lever brackets 2 and 3. In Fig. 1. the strongly drawn out illustration shows the normal position of the foot lever. By actuating the foot lever 1 in the direction of the arrow, after a dead center position has been exceeded, the direction of torque of the spiral spring 5 changes and the foot lever 1 reaches its end position. When the invention is applied to a clutch, this would correspond to the disengaged state of the clutch (shown in dash-dotted lines).
