Abstract

The Kickdown element has a housing (1) and a spring (3). There are movable arms (4) on the base surface of the housing, perpendicular to it. The housing is closed by a covering cap (2). The arms are stressed against sliding surfaces (6) by the spring.

Description

Die Erfindung betrifft ein Kickdown-Element für einen Fahrpedalgeber, welches ein Gehäuse und eine Feder aufweist.The invention relates to a kickdown element for one Accelerator pedal encoder, which is a housing and has a spring.

Ein derartiges Kickdown-Element ist aus der deutschen Patentschrift DE 195 21 821 C1 bekannt. Bei diesem Kickdown-Element weist der Fahrpedalhebel eine angeformte Nase auf, welche in einem vorgegebenen Auslenkungsbereich, also dem Kickdown-Bereich, die Schenkel einer im wesentlichen U-förmig ausgebildeten Blattfeder auseinander drückt, wobei die Endabschnitte der Federschenkel an den Mantelflächen zweier im Gehäuse des Kickdown-Elementes gelagerten Zylinderrollen anliegen.Such a kickdown element is from the German patent DE 195 21 821 C1 known. In this kickdown element, the accelerator pedal lever has a molded nose which, in a predetermined deflection area, i.e. the kickdown area, presses the legs of a substantially U-shaped leaf spring apart, the end sections of the spring legs on the lateral surfaces of two in the housing of the Kickdown element mounted cylindrical rollers.

Die Montage dieses bekannten Kickdown-Elementes aus Gehäuse, Zylinderrollen und Blattfeder ist relativ aufwendig und damit auch kostenaufwendig. Hinzu kommt, daß diese Anordnung relativ genau bezüglich der am Fahrpedalhebel angeformten Nase positioniert sein muß und daher die gesamte Kickdownanordnung sehr toleranzempfindlich ist. Ein weiterer Nachteil ist durch die relativ kurze Lebensdauer der Blattfeder gegeben.The assembly of this well-known kickdown element from housing, Cylindrical rollers and leaf springs are relatively complex and therefore also costly. In addition, this arrangement is relatively accurate in terms of the nose formed on the accelerator pedal lever must be positioned and therefore the entire kickdown arrangement is very sensitive to tolerances. On Another disadvantage is the relatively short life of the leaf spring given.

Es ist die Aufgabe der Erfindung ein besonders einfach und kostengünstiges Kickdown-Element zu schaffen, welches die vorgenannten Nachteile vermeidet.It is the object of the invention a particularly simple and inexpensive kickdown element too create, which avoids the aforementioned disadvantages.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Grundfläche des Gehäuses bewegliche, sich senkrecht zur Grundfläche erstreckende Arme angeformt sind, daß das Gehäuse durch eine Abdeckkappe abgeschlossen ist und daß die beweglichen Arme mittels der Feder an Gleitflächen der Abdeckplatte vorgespannt sind.This object is achieved according to the invention solved, that at the base area housing movable, perpendicular to the base extending arms are integrally formed that the housing by a cover cap is complete and that the movable arms biased by the spring on sliding surfaces of the cover plate are.

Das erfindungsgemäße Kickdownelement besteht damit aus nur noch drei Einzelteilen, die besonders kostengünstig hergestellt und montiert werden können.The kickdown element according to the invention exists thus from only three individual parts, which are manufactured particularly cost-effectively and can be assembled.

Der Aufbau ist zudem besonders robust, so daß das Kickdown-Element sich durch eine fange Lebensdauer auszeichnet. Besonders vorteilhaft ist zudem, daß zur Betätigung des Kickdown-Element kein mit dem Fahrpedalhebel verbundenes Gegenstück benötigt wird, wodurch keine hohen Anforderungen an die Einhaltung von Einbautoleranzen erforderlich sind.The structure is also particularly robust, so that Kickdown element is characterized by a long lifespan. It is also particularly advantageous that the actuation of the kickdown element no counterpart connected to the accelerator pedal lever is required, which means no high ones Requirements for compliance with installation tolerances are required.

Im folgenden wird ein Ausführungsbeispiel des erfindungsgemäßen Kickdown-Elementes anhand der Zeichnung dargestellt und näher erläutert.In the following an embodiment of the kickdown element according to the invention shown in the drawing and closer explained.

Die einzige Figur zeigt eine Schnittzeichnung eines erfindungsgemäß aufgebautes Kickdown-Elements.The only figure shows a sectional drawing of a constructed according to the invention Kickdown element.

Das in der Figur dargestellte Kickdown-Element besteht aus nur noch drei Einzelteilen, nämlich einem Gehäuse (1), einer Abdeckkappe (2) und einer Feder (3). Am Gehäuse (1) sind einstückig bewegliche Arme (4) über Filmscharniere (5) angeformt.The kickdown element shown in the figure consists of only three individual parts, namely a housing ( 1 ), a cover cap ( 2 ) and a spring ( 3 ). On the housing ( 1 ) are one-piece movable arms ( 4 ) about film hinges ( 5 ) molded.

Die Funktion des Kickdown-Elements wird dadurch realisiert, daß die beiden beweglichen Arme (4) mit der Feder (3) an Gleitflächen (6) der Abdeckkappe (2) vorgespannt sind. Wird die Abdeckkappe (2) niedergedrückt, werden die beiden beweglichen Arme (4) über die Gleitflächen (6) nach innen gedrückt. Die sich dadurch ergebende Schrägstellung der Arme (4) erzeugt dann die für die Rückstellung der Abdeckkappe (2) erforderliche Kraft.The function of the kickdown element is realized in that the two movable arms ( 4 ) with the spring ( 3 ) on sliding surfaces ( 6 ) the cap ( 2 ) are biased. If the cover cap ( 2 ), the two movable arms ( 4 ) over the sliding surfaces ( 6 ) pressed inwards. The resulting inclination of the arms ( 4 ) then generates the for resetting the cover cap ( 2 ) required force.

In der Ruhestellung wird die Position zwischen der Abdeckplatte (2) und dem Gehäuse (1) durch am Gehäuse (1) und an der Abdeckplatte (2) angeformte Rasthaken (7, 8) festgelegt. Diese Rasthaken (7, 8) ermöglichen zudem eine besonders einfache Montage der Abdeckplatte (2) am Gehäuse (1) durch einfaches Aufdrücken.In the rest position, the position between the cover plate ( 2 ) and the housing ( 1 ) on the housing ( 1 ) and on the cover plate ( 2 ) molded snap hooks ( 7 . 8th ). These locking hooks ( 7 . 8th ) also enable a particularly simple assembly of the cover plate ( 2 ) on the housing ( 1 ) by simply pressing it on.

Die Kraftcharakteristik des Kickdown-Elements kann über die Kontur der Gleitflächen (6) sowie die Auslegung der Feder (3) vorgegeben werden.The force characteristic of the kickdown element can be determined via the contour of the sliding surfaces ( 6 ) and the design of the spring ( 3 ) can be specified.
