Description

Die Erfindung bezieht sich auf ein Pedal für ein Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to a pedal for a motor vehicle according to the preamble of claim 1.

Aus der DE-A 34 27 097 ist ein Kupplungspedal für ein Kraftfahrzeug bekannt, dessen Pedalarm einstückig aus Kunststoff besteht und zwischen zwei Stegen angeordnete Verrippungen aufweist. Diese sollen eine erforderliche Steifigkeit bewirken und die relativ großen Torsions- und Biegebelastungen aufnehmen, denen das Pedal im Betrieb ausgesetzt ist. Um diese Bedingungen zu erfüllen, muß ein mit einer Verrippung versehener Pedalarm sehr massiv ausgeführt werden, was zu einer Erhöhung des Gewichts und einem maßlich größeren Pedal führt.From DE-A 34 27 097 a clutch pedal for a motor vehicle is known, the pedal arm is made in one piece from plastic and has ribs arranged between two webs. These are said to provide the required rigidity and to absorb the relatively large torsional and bending loads to which the pedal is exposed during operation. To meet these conditions, a ribbed pedal arm must be made very solid, which leads to an increase in weight and a larger pedal.

Der Erfindung liegt die Aufgabe zugrunde, ein Kupplungspedal für ein Kraftfahrzeug zu schaffen, das bei geringem Gewicht kleinbauend und mit großer Steifheit ausgeführt ist.The invention has for its object to provide a clutch pedal for a motor vehicle, which is small and lightweight with great rigidity.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved according to the invention by the characterizing features of claim 1. The dependent claims contain further advantageous features.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß ein im Spritzgußverfahren einfach herzustellendes Pedal geschaffen wird, das aufgrund seines Aufbaues als Hohlprofil eine solche Steifheit aufweist, daß ein verbiegendes Nachgeben des Pedalarmes auch bei ungleichmäßigen und heftigen Belastungen unterbunden wird. Durch die Ausbildung als Hohlprofil mit einem rechteckförmigen Querschnitt sind relativ große Torsions- und Biegebelastungen aufzunehmen.The main advantages achieved by the invention are that a pedal that is easy to manufacture by injection molding is created, which due to its construction as a hollow profile has such a stiffness that bending of the pedal arm is prevented even under uneven and violent loads. Due to the design as a hollow profile with a rectangular cross section, relatively large torsional and bending loads can be absorbed.

Das Hohlprofil ist aufgrund seiner geringen Masse leicht und kann entsprechend der räumlichen Gegebenheiten kleinbauend ausgeführt werden.The hollow profile is light due to its low mass and can be made small in accordance with the spatial conditions.

Die Herstellung des Pedals in Kunststoff ist kostengünstig, da nur zwei Kerne verwendet werden, mit denen die beiden Abschnitte des Pedalarmes jeweils bis zur Abknickung in einer Spritzgußform hergestellt werden können.The production of the pedal in plastic is inexpensive, since only two cores are used, with which the two sections of the pedal arm can each be produced in an injection mold up to the point of kinking.

Das Hohlprofil weist einen rechteckförmigen Querschnitt auf und ist mit Wandungen annähernd gleicher Dicke versehen, die bis auf Anformungen für Lagerungen und Ausnehmungen innen- und außenseitig glattflächig ausgeführt sind.The hollow profile has a rectangular cross-section and is provided with walls of approximately the same thickness, which are smooth on the inside and outside, except for formations for bearings and recesses.

Am Pedalarm ist endseitig eine Trittplatte angeformt, welche Teil des Hohlprofils ist und dessen Trittfläche sich über Verstärkungsrippen gegen ein Abbrechen am Profil abstützen kann. An dem der Trittfläche abgekehrten anderen Ende des Pedalarmes ist ein Federarm angeformt, der ein gegabeltes Ende mit einer Lagerbohrung umfaßt.A pedal plate is formed on the end of the pedal arm, which is part of the hollow profile and the tread surface of which can be supported by reinforcing ribs to prevent the profile from breaking off. At the other end of the pedal arm facing away from the tread surface, a spring arm is formed, which comprises a forked end with a bearing bore.

Ein Pedalarm aus Kunststoff kann in einfacher Weise an verschiedene Fahrzeugtypen angepaßt werden, indem von vornherein schon entsprechende Bohrungen bzw. Öffnungen im Pedalarm vorgesehen werden und somit ein vielseitig einsetzbares Pedal aus einem Stück ohne wesentlichen Mehraufwand geschaffen wird, was die Lagerhaltung wesentlich vereinfacht.A pedal arm made of plastic can be easily adapted to different vehicle types by providing appropriate bores or openings in the pedal arm from the outset and thus creating a versatile pedal from a single piece without significant additional effort, which considerably simplifies storage.

Das Pedal 1 für ein Kraftfahrzeug umfaßt im wesentlichen einen Pedalarm 2 mit einer Tragplatte 3 und einem Federhebel 4. Es besteht aus Kunststoff und wird einstückig im Spritzgußverfahren aus einem glasfaserverstärkten Polyamid hergestellt.The pedal 1 for a motor vehicle essentially comprises a pedal arm 2 with a support plate 3 and a spring lever 4. It is made of plastic and is produced in one piece by injection molding from a glass fiber reinforced polyamide.

Der Pedalarm 2 besteht aus einem Hohlprofil z.B. rechteckförmigen Querschnitts, das sich vom vorderen Armende 5 mit der Trittplatte 3 bis zum hinteren Armende 6 mit dem Federhebel 4 erstreckt. Der Arm 2 umfaßt zwei Abschnitte 9, 10, die sich bis zu einer Abknickung 7 jeweils von den Armenden 5 und 6 ausgehend verjüngen. Im zusammentreffenden Bereich dieser beiden Abschnitte 5 und 6 ist im Inneren des Hohlprofils eine umlaufende Innenrippe 8 gebildet. Diese Ausbildung des Pedalarmes 2 ergibt einerseits im Bereich großer Belastungen einen relativ großen Querschnitt des Pedalarmes und andererseits kann das Pedal 1 mittels zweier Kerne hergestellt werden, die jeweils eine Länge bis zur Rippe 8 aufweisen und hier ineinandergesteckt sind. Wie insbesondere die Figuren 3 und 4 zeigen, sind die Wandungen des Hohlprofils durchgehend von annähernd gleicher Dicke und außen- sowie innenseitig weitestgehend glattflächig ausgeführt, wobei die Außenfläche Rippungen sowie Anformungen aufweisen kann.The pedal arm 2 consists of a hollow profile e.g. rectangular cross-section that extends from the front arm end 5 with the tread plate 3 to the rear arm end 6 with the spring lever 4. The arm 2 comprises two sections 9, 10 which taper up to a bend 7, each starting from the arm ends 5 and 6. In the area where these two sections 5 and 6 meet, a circumferential inner rib 8 is formed in the interior of the hollow profile. This design of the pedal arm 2 results, on the one hand, in the area of high loads, a relatively large cross section of the pedal arm and, on the other hand, the pedal 1 can be produced by means of two cores, each of which has a length up to the rib 8 and are inserted one into the other here. As particularly shown in FIGS. 3 and 4, the walls of the hollow profile are of approximately the same thickness and are largely smooth on the outside and inside, the outer surface being able to have ribs and projections.

Der erste Abschnitt 9 des Pedalarmes 2 weist an seinem hinteren Armende 6 einen Federhebel 4 auf, der abgewinkelt zum gestreckten Pedalarm 2 angeordnet ist. Dieser ist im Querschnitt U-profilförmig ausgeführt und weist zwischen seinen Schenkeln 11 und 12 (Fig. 7) quer verlaufende Verstärkungsrippen 13, 14 auf, wobei zwischen der Rippe 14 und einer Rückwand 15 des Hohlprofils eine quer verlaufende Lagerbohrung 16 angeordnet ist. Diese ist in an einer Seitenwand 17, 17a des Pedalarmes 2 angeformten Hülse 18 fortgeführt, welche durch radiale Verstärkungsrippen 19 zum Pedalarm 2 hin abgestützt ist.The first section 9 of the pedal arm 2 has on its rear arm end 6 a spring lever 4 which is arranged at an angle to the extended pedal arm 2. This is U-shaped in cross section and has transverse reinforcing ribs 13, 14 between its legs 11 and 12 (FIG. 7), a transverse bearing bore 16 being arranged between the rib 14 and a rear wall 15 of the hollow profile. This is continued in a sleeve 18 formed on a side wall 17, 17a of the pedal arm 2, which is supported by radial reinforcing ribs 19 towards the pedal arm 2.

Unterhalb der Lagerbohrung 16 im Pedalarm 2 sind weitere quer verlaufende achsgleiche Bohrungen 20 in den Seitenwänden 17, 17a vorgesehen, denen in der Rückwand 15 eine Öffnung 21 zum Durchführen einer Druckstange für einen Geberzylinder zugeordnet ist.Below the bearing bore 16 in the pedal arm 2, further transverse axially aligned bores 20 are provided in the side walls 17, 17a, to which an opening 21 in the rear wall 15 is assigned for the passage of a push rod for a master cylinder.

Das vordere Ende 5 des Pedalarmes 2 trägt die Trittplatte 3, welche zu einer Seitenwand 17 des Pedals 1 über Rippen 22 abgestützt ist. Diese verlaufen - in bezug auf die Fahrtrichtung F - in Längsrichtung und sind mit Abstand übereinander angeordnet. Wie Fig. 8 näher zeigt, ist das vordere Ende 5 im Querschnitt U-profilförmig ausgebildet, wobei der Steg 23 Teil der Trittplatte 3 ist und die Stirnwand 24 des Hohlprofils bildet.The front end 5 of the pedal arm 2 carries the tread plate 3, which is supported on a side wall 17 of the pedal 1 via ribs 22. In relation to the direction of travel F, these run in the longitudinal direction and are arranged at a distance from one another. As FIG. 8 shows in more detail, the front end 5 is U-shaped in cross section, the web 23 being part of the tread plate 3 and forming the end wall 24 of the hollow profile.

Das Hohlprofil ist an seinen freien Enden 5 und 6 jeweils offengelassen und weist zwischen dem ersten Abschnitt 9 und dem zweiten Abschnitt 10 in der Abknickung 7 eine Ausrundung 26 auf. Eine weitere Ausrundung 25 ist zwischen dem Federhebel 4 und dem ersten Abschnitt 9 des Pedalarmes 2 vorgesehen.The hollow profile is left open at its free ends 5 and 6 and has a fillet 26 in the bend 7 between the first section 9 and the second section 10. Another fillet 25 is provided between the spring lever 4 and the first section 9 of the pedal arm 2.
