Description

Die Erfindung betrifft eine Pedalvorrichtung, insbesondere zum Betätigen einer Kfz-Kupplung, der im Oberbegriff des Patentanspruchs 1 genannten Art, wie sie beispielsweise bekannt ist aus der EP 0 480 602-A1.The invention relates to a pedal device, in particular for actuating a motor vehicle clutch, of the type mentioned in the preamble of patent claim 1, as is known for example from EP 0 480 602-A1.

Bei Pedalvorrichtungen übliche Übertotpunktfeder-Anordnungen werden eingesetzt, um - nach Überschreiten ihres sogenannten Totpunktes - die erforderlichen Pedalbetätigungskräfte zu reduzieren. Im Automobilbau, insbesondere bei Personenkraftwagen, kann so in vielen Fällen auf eine sonst erforderlich werdende hydraulische Servounterstützung verzichtet werden. Neben Anordnungen, bei denen die Übertotpunktfeder als Druckfeder in Form einer auf einer Vorzugsweise teleskopierbaren Führungsstange gelagerten Schraubenfeder ausgebildet ist (z. B. DE 29 23 027-C2; DE 38 41 719-C2), sind auch Pedalvorrichtungen bekannt (z. B. EP 0 480 602-A1), bei denen als Übertotpunktfeder eine Blattfederanordnung vorgesehen ist.
Diese Blattfederanordnung besteht vorzugsweise aus einem Paket von mehreren aufeinandergestapelten Federblättern, die exakt in der Schwenkebene des Pedals angeordnet sind und mit ihrem einen Ende fest und starr in einen aufbaufesten Montageblock eingespannt sind.Conventional over-center spring arrangements are used in pedal devices in order to reduce the required pedal actuation forces after their so-called dead center has been exceeded. In automobile construction, particularly in the case of passenger cars, hydraulic servo assistance, which would otherwise be necessary, can thus be dispensed with in many cases. In addition to arrangements in which the dead center spring is designed as a compression spring in the form of a helical spring mounted on a preferably telescopic guide rod (e.g. DE 29 23 027-C2; DE 38 41 719-C2), pedal devices are also known (e.g. EP 0 480 602-A1), in which a leaf spring arrangement is provided as the dead center spring.
This leaf spring arrangement preferably consists of a package of several stacked spring leaves, which are arranged exactly in the pivoting plane of the pedal and are firmly and rigidly clamped at one end in a mounting block which is fixed to the structure.

Das schwenkbare Pedal stützt sich mit dem rollenbewehrten freien Ende eines abgewinkelten Pedalarms auf dem Blattfederpaket ab, und zwar im Bereich des freien Federendes.The pivotable pedal is supported with the roller-reinforced free end of an angled pedal arm on the leaf spring assembly, in the area of the free spring end.

Beim Betätigen des Pedals rollt die am freien Ende des abgewinkelten Pedalarms gelagerte Rolle auf dem auf Biegung beanspruchten vorgespannten Blattfederpaket ab, wobei Blattfederpaket und Pedal derart ausgebildet und räumlich zueinander ausgerichtet sind, daß das Blattfederpaket einerseits auf das in seiner Ruhelage befindliche Pedal eine diese Ruhelage unterstützende Federkraft ausübt und andererseits bei Betätigung des Pedals nach Überschreiten einer noch in der Nähe der Pedalruhelage befindlichen sogenannten Übertotpunktlage auf das Pedal eine die Betätigungskraft unterstützende Federkraft ausübt.When the pedal is pressed, the roller mounted on the free end of the angled pedal arm rolls on the pretensioned leaf spring assembly, the leaf spring assembly and pedal are designed and spatially aligned with one another such that the leaf spring assembly on the one hand on the pedal in its rest position supports this rest position Exerts spring force and on the other hand exerts a spring force supporting the actuation force when the pedal is actuated after exceeding a so-called dead center position still located in the vicinity of the pedal rest position.

Diese vorbekannte Anordnung ist konstruktiv und fertigungstechnisch ähnlich aufwendig und damit ähnlich teuer wie vorbekannte Anordnungen mit auf teleskopierbaren Führungsstangen gelagerten Schraubendruckfedern.This known arrangement is structurally and technically similarly complex and thus similarly expensive as known arrangements with helical compression springs mounted on telescopic guide rods.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Pedalvorrichtung der im Oberbegriff des Patentanspruchs 1 genannten Art zu schaffen, die konstruktiv einfach ist und sich durch Montagefreundlichkeit und Zuverlässigkeit auszeichnet.Against this background, the invention has for its object to provide a pedal device of the type mentioned in the preamble of claim 1, which is structurally simple and is characterized by ease of installation and reliability.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous refinements and developments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Pedalvorrichtung wird als Übertotpunktfeder ein einfach zu fertigendes vorgespanntes flaches Federblatt eingesetzt, das derart ausgebildet und in die Pedalvorrichtung eingebaut ist, daß es auf Knickung beansprucht wird. Ein solches vorgespanntes flaches Federblatt stellt ein besonders kostengünstiges und bezüglich seiner Funktion bewährtes und zuverlässiges Bauelement dar, das darüber hinaus auch vergleichsweise einfach zu montieren und zu demontieren ist.In the pedal device according to the invention, an easy-to-manufacture, prestressed flat spring leaf is used as the over-center spring, which is designed and installed in the pedal device such that it is subjected to buckling. Such a pretensioned flat spring leaf is a particularly cost-effective component which has been proven and reliable in terms of its function, and which is also comparative is easy to assemble and disassemble.

Anhand einiger in der Zeichnung dargestellter Ausführungsbeispiele wird die Erfindung nachstehend näher erläutert.The invention is explained in more detail below with the aid of a few exemplary embodiments shown in the drawing.

In Fig. 1 ist ein Pedal, beispielsweise das Kupplungspedal eines Kraftfahrzeugs schwenkbar um eine aufbaufeste Lagerachse 2 gelagert.In Fig. 1, a pedal, for example the clutch pedal of a motor vehicle is pivotally mounted about a mounting axis 2 fixed.

Dargestellt sind die beiden räumlichen Grenzpositionen des Pedals, nämlich einmal - voll ausgezogen - das mit 1 bezifferte voll bis zur Anlage an einen Anschlag 11 durchgetretene Pedal und - gestrichelt dargestellt - das in seiner Ruhelage befindliche und mit 1' bezifferte Pedal.The two spatial limit positions of the pedal are shown, namely once - fully extended - the pedal, which is numbered 1 as far as it will come to rest against a stop 11, and - shown in dashed lines - the pedal which is in its rest position and which is numbered 1 '.

Zwischen Pedal 1 und dem nicht weiter dargestellten Aufbau bzw. einem aufbaufesten Bauteil 12 ist eine als Übertotpunktfeder wirkende Blattfederanordnung angeordnet.Between pedal 1 and the construction (not shown) or a construction-fixed component 12 is an over-center spring acting leaf spring arrangement arranged.

Diese Blattfederanordnung ist als einfaches flaches Federblatt 3 von etwa C-Form ausgebildet, wie in Fig. 2 erkennbar.This leaf spring arrangement is designed as a simple flat spring leaf 3 of approximately C-shape, as can be seen in FIG. 2.

Es ist vorgespannt in die Pedalvorrichtung eingebaut und wird auf Knickung beansprucht. Es stützt sich mit seinen beiden Enden jeweils gelenkig einerseits an einem aufbaufesten Widerlager 4 und andererseits an einem pedalseitigen Widerlager 5 ab.It is preloaded in the pedal device and is subjected to buckling. With its two ends, it is supported in an articulated manner on the one hand on an abutment 4 fixed to the structure and on the other hand on an abutment 5 on the pedal side.

Bei in Ruhelage befindlichen Pedal 1' nimmt es räumlich die in Fig. 1 strichpunktiert dargestellte und mit 3' bezifferte Lage ein, wobei eine in Fig. 2 mit F₂ bezifferte Federkraft wirksam ist.When the pedal 1 'is in the rest position, it spatially occupies the position shown in broken lines in FIG. 1 and numbered 3', a spring force numbered F₂ in FIG. 2 being effective.

Die hierbei wirksame, durch die beiden Widerlager 4 bzw. 5' verlaufende Federkraftwirkrichtung 13' verläuft dabei unterhalb der aufbaufesten Lagerachse 2 und übt so wie gewünscht eine das Pedal in seiner Ruhelage haltende Kraft aus.The effective spring force acting direction 13 ', which runs through the two abutments 4 and 5', runs below the fixed bearing axis 2 and, as desired, exerts a force holding the pedal in its rest position.

Bei niedergetretenem Pedal 1 verläuft die durch die beiden Widerlager 4 bzw. 5 hindurchgelegte Federkraftwirkrichtung 13 dagegen oberhalb der aufbaufesten Lagerachse 2, so daß die vorgespannte Blattfederanordnung 3 auf das Pedal eine die Betätigungskraft P unterstützende Kraft F₁ (Fig. 2) ausübt.When the pedal 1 is depressed, the spring force acting direction 13 placed through the two abutments 4 and 5, on the other hand, extends above the fixed bearing axis 2, so that the prestressed leaf spring arrangement 3 exerts an actuating force P on the pedal force F 1 (FIG. 2).

Die gelenkige Ankopplung des C-förmigen Federblatts 3 an die beiden Widerlager 4 bzw. 5 erfolgt in diesem Ausführungsbeispiel ohne an den Federenden angeformte Federösen. Stattdessen sind an den beiden freien Enden des C-förmigen flachen Federblatts 3 jeweils konkave Lagerpfannen 8 bzw. 9 eingeformt, mit welchen sich das Federblatt an damit korrespondierenden konvexen Zylinderflächen 6 bzw. 7 der beiden Widerlager 4 bzw. 5 abstützt. Diese Zylinderflächen 6, 7 sind dabei zueinander sowie zur aufbaufesten Lagerachse 2 parallel ausgerichtet. Das eingebaute Federblatt 3 liegt somit quasi "lose" zwischen den beiden Widerlagern 4, 5.In this exemplary embodiment, the articulated coupling of the C-shaped spring leaf 3 to the two abutments 4 and 5 takes place without spring eyes molded onto the spring ends. Instead, concave bearing pans 8 and 9, respectively, are formed on the two free ends of the C-shaped flat spring leaf 3, with which the spring leaf is supported on corresponding convex cylindrical surfaces 6 and 7 of the two abutments 4 and 5. These cylinder surfaces 6, 7 are aligned parallel to one another and to the bearing axis 2 fixed to the body. The built-in spring leaf 3 thus lies “loosely” between the two abutments 4, 5.

Im in Fig. 3 dargestellten Ausführungsbeispiel enthalten die beiden Widerlager 4, 5 keine parallel zur Lagerachse 2 ausgerichtete konvexe Zylinderflächen, sondern etwa parallel zur Lagerachse 2 ausgerichtete konkave Lagerpfannen 14, 15, in denen sich das vorgespannte flache Federblatt 3 mit seinen freien Enden gelenkig abstützt, wozu an den beiden freien Enden des Federblatts jeweils mit diesen konkaven Lagerpfannen 14, 15 korrespondierende konvexzylindrische Lagerflächen angeordnet sind.In the embodiment shown in Fig. 3 contain the two abutments 4, 5 no convex cylindrical surfaces aligned parallel to the bearing axis 2, but rather concave bearing pans 14, 15 aligned approximately parallel to the bearing axis 2, in which the pretensioned flat spring leaf 3 is supported with its free ends in an articulated manner, for which purpose at the two free ends of the spring leaf Corresponding convex-cylindrical bearing surfaces are each arranged with these concave bearing pans 14, 15.

Wie in Fig. 6 angedeutet ist, könnten hierzu die beiden freien Enden des Federblatts 3 selbst zu mit den konkaven Lagerpfannen 14 bzw. 15 korrespondierenden konvexzylindrischen Lagerflächen 16, 17 gebogen sein.As indicated in FIG. 6, for this purpose the two free ends of the spring leaf 3 itself could be bent into convex-cylindrical bearing surfaces 16, 17 corresponding to the concave bearing pans 14 and 15, respectively.

Fertigungstechnisch einfach und funktionell vorteilhafter ist es jedoch, die freien Enden des Federblatts 3 mit mit den konkaven Lagerpfannen 14, 15 korrespondierenden zylindrischen Kunststoffwalzen 18, 19 auszustatten, wie dies in den Detaildarstellungen der Figuren 4 und 5 zu erkennen ist. Die jeweils etwa parallel zur Lagerachse 2 ausgerichteten Kunststoffwalzen 18, 19 sind dabei jeweils mit einem nicht weiter bezifferten Längsschlitz versehen, in welche die freien Enden des Federblatts 3 eingesteckt sind.It is, however, technically simple and functionally advantageous to provide the free ends of the spring leaf 3 with cylindrical plastic rollers 18, 19 corresponding to the concave bearing pans 14, 15, as can be seen in the detailed representations of FIGS. 4 and 5. The plastic rollers 18, 19, each aligned approximately parallel to the bearing axis 2, are each provided with a longitudinal slot, not further numbered, into which the free ends of the spring leaf 3 are inserted.

Durch Wahl eines Kunststoffes mit guten Gleiteigenschaften ist bei dieser Ausführungsform auch ohne Einsatz zusätzlicher Gleitmittel unabhängig vom jeweiligen Material der Widerlager 4, 5 (Metall oder Kunststoff) bei Betätigung des Pedals 1 stets ein geräuschfreies Arbeiten gewährleistet.By choosing a plastic with good sliding properties, no noise is guaranteed in this embodiment, even without the use of additional lubricants, regardless of the material of the abutments 4, 5 (metal or plastic) when the pedal 1 is actuated.

Von Vorteil ist es, zumindest eines der beiden Widerlager 4, 5, vorzugsweise aber wie im dargestellten Ausführungsbeispiel beide Widerlager jeweils mit seitlichen Lagerwangen 10 auszustatten, um ein eventuelles seitliches Abrutschen oder Wegwandern des Federblatts 3 während des Betriebes mit Sicherheit zu verhindern.It is advantageous to equip at least one of the two abutments 4, 5, but preferably, as in the exemplary embodiment shown, both abutments each with lateral bearing cheeks 10 in order to reliably prevent any possible slipping or wandering away of the spring leaf 3 during operation.
