The mechanical coupling between the two parts is provided by a rack and pinion coupling. This allows the overall length of the pedal to be varied to different drivers.

Description

Die Erfindung bezieht sich auf ein verstellbares Pedal bestehend aus einem um eine Pedalachse verschwenkbaren Druckstangenhebel mit einer daran angelenkten Druckstange und aus einem Pedalhebel, an dessen unterem Ende eine Pedalplatte angeordnet und der in einer Schiene am Druckstangenhebel geführt ist.The invention relates to an adjustable Pedal consisting of a pivotable around a pedal axis Push rod lever with an articulated on it Push rod and from a pedal lever on the lower End arranged a pedal plate and the in a Rail is guided on the push rod lever.

In einem Fahrzeug dienen Pedale der Betätigung der Bremse sowie der Kupplung und als Steuerorgan zur Leistungsregelung des Antriebsmotors. Sie sind in einer definierten Position im Fußraum der Fahrgastzelle untergebracht. Es wurde schon vorgeschlagen, die Pedale verstellbar einzurichten, so daß der Fahrer deren Positionen in Relation zur Sitzposition seinen Bedürfnissen anpassen kann, ohne dabei den Sitz zu nahe an das Lenkrad heranführen zu müssen. Dazu wird jedes der Pedale zweiteilig ausgeführt: Es besteht jeweils aus einem Druckstangenhebel, der drehbar um eine Pedalachse gelagert und an dem ein Betätigungsorgan angelenkt ist, und aus einem Pedalhebel mit einer Pedalplatte, der verschiebbar gegenüber dem Druckstangenhebel angeordnet ist. Bei einer Verschiebung des Pedalhebels gegenüber dem Druckstangenhebel verändert sich aber nicht nur die Lage der Pedalplatte in der Fahrgastzelle sondern gleichzeitig deren relative Position zur Pedalachse, was eine nicht gewünschte Änderung des Übersetzungsverhältnisses hervorruft. Pedals are used for actuation in a vehicle the brake and the clutch and as a control element for Power control of the drive motor. You are in one defined position in the footwell of the passenger compartment. It has already been suggested that the pedals be adjustable set up so that the driver's positions adapt to his needs in relation to the seating position can, without bringing the seat too close to the steering wheel to have to. Each of the pedals is made in two parts executed: It consists of a push rod lever, which rotates around a pedal axis and on which an actuator is articulated, and from a pedal lever with a pedal plate that is slidable opposite the push rod lever is arranged. With a shift of the pedal lever compared to the push rod lever changed but not only the position of the pedal plate the passenger compartment but at the same time their relative position to the pedal axis, which is an undesirable change of the gear ratio.

Der Erfindung liegt die Aufgabe zugrunde, dieses System weiter zu verbessern. Insbesondere soll erreicht werden, daß das Übersetzungsverhältnis bei einer Verstellung im wesentlichen konstant bleibt. Außerdem soll das Pedal möglichst einfach aufgebaut sein und eine elektromotorische Verstellung ermöglichen.The invention has for its object this System to improve further. In particular, should be achieved be that the gear ratio at a Adjustment remains essentially constant. Moreover the pedal should be as simple as possible and one enable electromotive adjustment.

Es wird vorgeschlagen, daß die Schiene zur Führung des Pedalhebels gekrümmt verläuft, wobei der Mittelpunkt der Krümmung so angeordnet ist, daß bei einer Verstellung die Pedalplatte im wesentlichen parallel zur Druckstange versetzt wird.It is suggested that the rail guide of the pedal lever is curved, with the center the curvature is arranged so that with an adjustment the pedal plate substantially parallel to Push rod is displaced.

Damit wird erreicht, daß das Übersetzungsverhältnis im wesentlichen konstant bleibt, wenn man von kleinen Abweichungen, die dem bogenförmigen Verlauf des Versatzweges geschuldet sind, absieht. Wird nun zusätzlich das Pedal im Fahrzeug so angeordnet, daß der Versatzweg horizontal verläuft, befindet das Pedal unabhängig von der eingestellten Position stets im selben Abstand zum Fahrzeugboden.This ensures that the gear ratio remains essentially constant when one of small deviations that correspond to the arcuate course of the Are due, disregards. Will now be additional the pedal in the vehicle arranged so that the offset path runs horizontally, the pedal is independent always at the same distance from the set position to the vehicle floor.

Eine sehr einfache Bauform der Schiene erhält man, wenn diese aus einer U-förmigen Lasche gebildet ist, zwischen deren Wangen der flach ausgeführte Pedalhebel verläuft.A very simple design of the rail is obtained one, if this is formed from a U-shaped tab, between their cheeks the flat pedal lever runs.

Dabei wird die gewünschte Krümmung dadurch erzielt, daß der Boden der U-förmigen Lasche gekrümmt verläuft und der Pedalhebel eine gekrümmt verlaufende, an diesem Boden anliegende äußere Kante aufweist. Diese Krümmung bestimmt letztlich den Weg der Pedalplatte bei einer Verstellung. Sie ist daher unter Berücksichtigung der sonstigen bauliche Gegebenheiten, wie der Orientierung der Druckstange und der Anordnung des Pedals in der Fahrgastzelle zu ermitteln.The desired curvature is achieved by that the bottom of the U-shaped tab is curved and the pedal lever is curved has this outer edge adjacent to the floor. This Curvature ultimately determines the path of the pedal plate an adjustment. It is therefore taken into account the other structural conditions, such as orientation the push rod and the arrangement of the pedal in the To determine the passenger compartment.

Damit der Pedalhebel gut geführt wird, liegt die innere, ebenfalls gekrümmt Kante des Pedalhebels an einer Abstützung in der Lasche an.So that the pedal lever is guided well, lies the inner, also curved edge of the pedal lever a support in the tab.

Um eine motorische Verstellung des Pedals realisieren zu können, wird vorgeschlagen, die innere Kante des Pedalhebels mit einer Verzahnung zu versehen und in der Lasche ein Ritzel drehbar zu lagern, das in die Verzahnung des Pedalhebels eingreift.To realize a motorized adjustment of the pedal to be able to, it is suggested the inner edge of the pedal lever with a toothing and in The bracket has a pinion that can be rotated in the toothing of the pedal lever engages.

Des weiteren wird das Schneckenrad eines Schneckenradgetriebes am Ritzel in koaxialer Anordnung befestigt, wobei die Schnecke des Schneckenradgetriebes außen an der Lasche drehbar gelagert ist.Furthermore, the worm wheel becomes one Worm gear on the pinion in a coaxial arrangement attached, the worm of the worm gear is rotatably mounted on the outside of the tab.

Eine bevorzugte Ausführung der Lasche besteht aus zwei zueinander spiegelbildlich aufgebauten Platten.A preferred embodiment of the tab exists from two plates that are mirror images of each other.

Die Lasche und der Pedalhebel sind vorzugsweise aus Metall hergestellt. Damit der Pedalhebel reibungsarm verstellt werden kann, sind zwischen dem Pedalhebel und der Lasche Gleitkörper angeordnet.The tab and pedal lever are preferred made of metal. So that the pedal lever has little friction can be adjusted between the pedal lever and arranged the tab sliding body.

An einer drehbar gelagerten Pedalwelle 1 ist ein Druckstangenhebel 2 befestigt, an dessen unterem Ende eine Druckstange 3 abgestützt ist, die zur Betätigung eines Bremszylinders oder Kupplungszylinders dient. Ebenfalls an der Pedalwelle 1 befestigt ist eine Schiene 4, die in etwa parallel zur Druckstange 3 angelegt und mit ihr verschweißt ist. Druckstangenhebel 2 und Schiene 4 bilden somit eine funktionelle Einheit.Is on a rotatably mounted pedal shaft 1 a push rod lever 2 attached to the lower end a push rod 3 is supported, which for actuating a Brake cylinder or clutch cylinder is used. Likewise fixed to the pedal shaft 1 is a rail 4, which are roughly parallel to the push rod 3 and with you are welded. Push rod lever 2 and rail 4 thus form a functional unit.

Die Schiene 4 ist aus einer umgebogenen Lasche mit zwei Wangen 5,5' und einem gekrümmt verlaufenden Boden 6 gebildet.The rail 4 is made of a bent tab with two cheeks 5.5 'and a curved bottom 6 formed.

Ein Pedalhebel 10 besteht aus einem oberen Führungsteil 7 und einem daran sich nach unten anschließenden Halteteil 8, an dessen unterem Ende eine Pedalplatte 9 befestigt ist. Führungsteil 7 und Halteteil 8 bilden in dieser Ausführung im Querschnitt ein flaches Oval. Der Querschnitt kann aber auch rechteckig sein, wie in der Fig. 3 dargestellt. Der Pedalhebel ist entweder massiv ausgeführt oder aus einem Blech entsprechend gebogen.A pedal lever 10 consists of an upper guide part 7 and one adjoining it downwards Holding part 8, at the lower end of a pedal plate 9 is attached. Guide part 7 and holding part 8 form in this version has a flat oval cross section. The Cross section can also be rectangular, as in the Fig. 3 shown. The pedal lever is either massive executed or bent from a sheet accordingly.

Das Führungsteil 7 ist über seine Länge gekrümmt ausgeführt, wie in der Fig. 2 dargestellt ist, wobei der Mittelpunkt der Krümmung etwa oberhalb des Versatzweges 15 der Pedalplatte 9 liegt, wobei berücksichtigt ist, daß die Druckstange 3 im wesentlichen horizontal verläuft, so daß der Versatzweg 15 parallel zur Druckstange 3 liegt.The guide part 7 is curved over its length executed, as shown in Fig. 2, wherein the center of the curvature approximately above the offset path 15 of the pedal plate 9 lies, taking into account is that the push rod 3 is substantially horizontal runs so that the offset path 15 parallel to Push rod 3 is.

Wie der Fig. 2 außerdem zu entnehmen ist, weist die Schiene 4 zur Führung des Führungsteils 7 eine korrespondierende Krümmung auf, wobei insbesondere der untere Bereich des Bodens 6 eine Abstützung 11 bildet. In der Schiene befindet sich etwa auf Höhe der Pedalwelle 1 ein Gegenstück 12 zur Aufnahme der auf das Pedal ausgeübten Betätigungskräfte.As can also be seen from FIG. 2, points the rail 4 for guiding the guide part 7 is a corresponding one Curvature, especially the lower one Area of the bottom 6 forms a support 11. In the Rail is approximately at the level of the pedal shaft 1 Counterpart 12 for receiving those exerted on the pedal Operating forces.

Hierbei handelt es sich um eine von einer der Wangen 5, 5' herausgebogene Lasche.This is one of the Cheeks 5, 5 'bent tab.

Die Schnittdarstellung der Fig. 2 zeigt zwei extreme Positionen der Pedaleinstellung. Aufgrund des gewählten Krümmungsmittelpunktes für das Führungsteil 7 ergibt sich zwischen den Extrempositionen ein etwa horizontaler Versatzweg 15 der Pedalplatte 9.The sectional view of FIG. 2 shows two extreme positions of the pedal setting. Because of the chosen Center of curvature for the guide member 7 results between the extreme positions a roughly horizontal Offset path 15 of the pedal plate 9.

Die Verstellung kann elektromotorisch erfolgen. Dazu ist unterhalb der Pedalwelle 1 ein Ritzel 13 drehbar an der Schiene 4 angeordnet. Dieses Ritzel 13 kämmt in einer Verzahnung 14 des Führungsteils 7. Ein Elektromotor zum Betätigen des Ritzels 13, der nicht mit dem Druckstangenhebel 2 verbunden sein muß, also beim Betätigen des Pedals nicht mitverschwenkt werden braucht, kann über eine flexible Welle mit dem Ritzel 13 verbunden sein. Der Elektromotor ist dann mit dem Fahrzeugkörper fest verbindbar. Denkbar wäre auch eine Verbindung des Ritzels 13 mit einem Getriebe, das einen seitlichen Versatz eines Verstellkolbens in eine Drehbewegung des Ritzels umsetzt.The adjustment can be done by an electric motor. For this purpose, a pinion 13 can be rotated below the pedal shaft 1 arranged on the rail 4. This pinion 13 meshes with a toothing 14 of the guide part 7. An electric motor to operate the pinion 13, which is not with the push rod lever 2 must be connected, so when you press of the pedal does not need to be swiveled over, can a flexible shaft can be connected to the pinion 13. The The electric motor can then be firmly connected to the vehicle body. A connection of the pinion 13 would also be conceivable with a gearbox that has a lateral offset of one Converting the piston into a rotary movement of the pinion.

Wie die Darstellung der Fig. 2 zeigt, wird eine Verdrehung des Ritzels 13 in eine entsprechende Verschiebung des Führungsteils 7 in der Schiene 4 umgesetzt, wodurch sich die Position der Pedalplatte 9 ändert. Beim Betätigen des Pedals verschwenkt die ganze Einheit um die Achse der Pedalwelle 1. Der Pedalhebel 10 stützt sich dabei an der Abstützung 11 und dem Gegenstück 12 ab. As the illustration in FIG. 2 shows, a Rotation of the pinion 13 in a corresponding displacement of the guide part 7 implemented in the rail 4, whereby the position of the pedal plate 9 changes. At the Operating the pedal pivots the whole unit around Axle of the pedal shaft 1. The pedal lever 10 is supported on the support 11 and the counterpart 12.

Fig. 3 zeigt in einer Explosionsdarstellung eine weitere Ausführung der Erfindung. Die Schiene 4 besteht aus zwei zueinander spiegelbildlich aufgebauten Platten 20, 21, mit jeweils einer gekrümmt verlaufenden Kante. An jeder Kante ist eine Führung 22, 23 rechtwinklig abgebogen, die übereinandergelegt die Führung des entsprechend gekrümmten Führungsteils 7 des Pedalhebels 10 bilden. Um eine reibungsarme Gleitfläche zu erhalten, ist an der innen liegenden Fläche des inneren Flansches ein Gleitstück 24 aus Teflon angelegt. Zur Bildung eines Widerlagers (entspricht Teil 12, Fig. 2) ist an den beiden Oberseiten der Platten 20, 21 jeweils ein Absatz vorgesehen, wobei der sich etwa senkrecht zur Oberkante erstreckende Abschnitt des Absatzes gekrümmt verläuft und mit einem Flansch 25 bzw. 26 als Widerlager versehen ist. Auch dieses kann mit einem Gleitstück 27 aus Teflon versehen werden.Fig. 3 shows an exploded view a further embodiment of the invention. The rail 4 is made two mirror images of each other Plates 20, 21, each with a curved Edge. A guide 22, 23 is rectangular at each edge bent, which superimposed the leadership of the correspondingly curved guide part 7 of the pedal lever 10 form. To get a low-friction sliding surface, is on the inner surface of the inner flange a slider 24 made of Teflon. To form a Abutment (corresponds to part 12, Fig. 2) is on the two A shoulder is provided on each of the top sides of the plates 20, 21, the one extending approximately perpendicular to the upper edge Section of the paragraph is curved and is provided with a flange 25 or 26 as an abutment. This can also be provided with a sliding piece 27 made of Teflon become.

Führung (Laschen 22, 23) und Widerlager (Flansche 25, 26) bilden einen Kanal, in dem das Führungsteil 7 des Pedalhebels 10 geführt ist. Im Bewegungsbereich des Führungsteils 7 sind an den Platten mehrere flache Gleitstücke 28 eingeknöpft, die den Pedalhebel 10 reibungsarm seitlich führen.Guide (tabs 22, 23) and abutment (Flanges 25, 26) form a channel in which the guide part 7 of the pedal lever 10 is guided. In the range of motion of the guide part 7 are several on the plates flat sliders 28 buttoned, the pedal lever 10th Guide sideways with little friction.

Auf Höhe der Flansch 25, 26 der Gegenführung befindet sich jeweils eine Öffnung, für die als Lagerrohr ausgeführte Pedalwelle 1, um deren Achse die ganze Anordnung bei einer Pedalbetätigung verschwenkt wird. Etwas unterhalb dieser Öffnung befinden sich zwei weitere Öffnungen zur Aufnahme eines Doppelzahnrades. Beim Doppelzahnrad handelt es sich um das schon erwähnte Ritzel 13 und um ein koaxial dazu angeordnetes Schneckenrad 29. Nach dem Zusammenbau befindet sich das Ritzel 13 zwischen den beiden Platten 20, 21, während sich das Schneckenrad 29 an der Außenseite der einen Platte 21 befindet. Dort kämmt es mit einer Schnecke 30, die mittels zweier Lagerwinkel 31 an der Außenseite der Platte 21 gehalten ist. Die Schnecke 30 kann zum Beispiel über ein flexibles Kabel von einem Elektromotor angetrieben werden.At the level of the flange 25, 26 of the opposite guide there is an opening for each as a bearing tube executed pedal shaft 1, around the axis of the whole arrangement is pivoted when the pedal is actuated. Something two further openings are located below this opening to accommodate a double gear. With the double gear is the pinion 13 already mentioned and a worm wheel 29 arranged coaxially thereto. After assembly, the pinion 13 is between the two plates 20, 21 while the worm wheel 29 is located on the outside of a plate 21. There it combs with a worm 30, which uses two bearing angles 31 is held on the outside of the plate 21. The screw 30 can, for example, via a flexible cable are driven by an electric motor.

Das Ritzel 13 kämmt in der Verzahnung 14 an der Innenkante des Führungsteil 7. Eine Drehung des Ritzels 13 ruft damit eine Verschiebung des Pedalhebels 10 in der durch die Führungen gebildeten Kanal hervor. Wegen der Krümmung von Führung und Pedalhebel, bewegt sich die Pedalplatte 9 ebenfalls auf einer schwach gekrümmten Bahn.The pinion 13 meshes in the toothing 14 on the Inner edge of the guide part 7. A rotation of the pinion 13 thus calls for a displacement of the pedal lever 10 in the channel formed by the guides. Because of the Curvature of the guide and pedal lever, the pedal plate moves 9 also on a slightly curved path.

Die Geometrie ist dabei so eingestellt, daß die Pedalplatte 9 in etwa parallel zur Druckstange versetzt wird und dabei einen etwa gleichbleibenden Abstand zur Fahrzeugboden einhält. Außerdem wird auf diese Weise der wirksame Hebelarm im wesentlichen konstant gehalten, so daß das Übersetzungsverhältnis durch eine Pedalverstellung nicht wesentlich geändert wird.The geometry is set so that the Pedal plate 9 offset approximately parallel to the push rod and while maintaining an approximately constant distance from Adheres to the vehicle floor. In addition, the effective lever arm kept essentially constant, so that the gear ratio through a pedal adjustment is not significantly changed.

Auf der Platte 20, die nicht mit der Schnecke versehen ist, wird an der Außenseite der Druckstangenhebel 2 in Form eines Befestigungswinkels angesetzt, an dem über eine Gabel die Druckstange 3 angelenkt ist. Eine Öffnung 32 dient der Aufnahme des Gabelstifts.On the plate 20, which is not with the snail is provided on the outside of the push rod lever 2 attached in the form of a mounting bracket on which the push rod 3 is articulated via a fork. A Opening 32 serves to receive the fork pin.
