Abstract

Biegsames Antriebsübertragungsorgan mit einer Verzahnung zum Eingriff eines Zahnrades, insbesondere für den Antrieb von Kfz-Schiebedächern und -Schiebefenstern. Um Klappergeräusche zu vermeiden und eine einfache, kostensparende Herstellung zu ermöglichen, ist das Antriebsübertragungsorgan als flexible Kunststoffzahnstange mit eingelagerter metallischer Verstärkung ausgebildet. Als Verstärkung kann zweckmäßig mindestens ein Stahlband vorgesehen sein, das Verstärkungselemente für die Zähne der Zahnstange trägt.Flexible drive transmission member with a toothing for engaging a gear, in particular for driving motor vehicle sunroofs and sliding windows. In order to avoid rattling noises and to enable simple, cost-saving manufacture, the drive transmission element is designed as a flexible plastic rack with embedded metallic reinforcement. As a reinforcement, at least one steel band can expediently be provided, which carries reinforcement elements for the teeth of the rack.

Description

Die Erfindung betrifft eine flexible Kunststoff-Zahnstange gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a flexible plastic rack according to the preamble of the patent claim.

Bei einer bekannten Zahnstange dieser Art (DE-OS 22 64 072) bildet das Stahlband eine Seele von in Längsrichtung konstanter Querscnniiisform und -abmessung, die in gewissem Abstand von den Zähnen liegt. Trotz der Verstärkung mittels des Stahlbandes ist aber die Übertragung von hohen Zug- und Druckkräften über die Zahnstange problematisch, weil die Kunststoffzähne ausreißen oder unzulässig verformt werden können. Für diese sind daher relativ große Kunststoff-Querschnitte vorzusehen.In a known rack of this type (DE-OS 22 64 072) the steel strip forms a core of in Longitudinal direction of constant cross-sectional shape and dimensions, which is at a certain distance from the teeth. Despite the reinforcement by means of the steel band, however, the transmission of high tensile and compressive forces is possible Problematic about the rack because the plastic teeth tear out or are impermissibly deformed can. For this reason, relatively large plastic cross-sections are to be provided.

Der Erfindung liegt die Aufgabe zugrunde, eine flexible Kunststoff-Zahnstange zu schaffen, die, bezogen auf ihre Quersc-.nittsabmessungen, besonders hohe Kräfte übertragen kann. Piese Aufgabe wird mit den Maßnahmen des kennzeichnenden Teils des Patentanspruchs gelöst.The invention is based on the object of creating a flexible plastic rack that, related can transmit particularly high forces on their cross-sectional dimensions. This task is done with the Measures of the characterizing part of the claim solved.

Die sich in die einzelnen Zähne hineinerstreckenden Laschen fangen auf die Zähne einwirkende Kräfte auf und übertragen sie auf den in Längsrichtung durch die Zahnstange hindurchlaufenden Teil des Stahlbandes.The tabs that extend into the individual teeth absorb forces acting on the teeth and transfer them to the part of the steel strip which runs in the longitudinal direction through the rack.

Die Zahnstange ist zweckmäßig als Spritz- oder Stranggußteil gefertigt. Dabei können an die Zahnstange je nach Bedarf Führungsteile und ähnliches, z. B.The rack is expediently manufactured as an injection or continuously cast part. You can use the rack depending on requirements guide parts and the like, z. B.

Die Erfindung ist im folgenden anhand von bevorzugten Ausführungsbeispielen näher erläutert In den Zeichnungen zeigtThe invention is explained in more detail below with reference to preferred exemplary embodiments shows the drawings

F i g. 1 einen Längsschnitt durch eine flexible, verstärkte Kunststoff-Zahnstange entlang Linie I-I der Fig. 2,F i g. 1 shows a longitudinal section through a flexible, reinforced plastic rack along line I-I of FIG Fig. 2,

F i g. 2 einen Querschnitt der Zahnstange nacH F i g. 1 entlang der Linie H-II1 F i g. 2 shows a cross section of the rack according to FIG. 1 along the line H-II 1

F i g. 3 eine Draufsicht auf das Stahlband der flexiblen Zahnstange nach den F i g. 1 und 2,F i g. 3 is a plan view of the steel band of the flexible rack according to FIGS. 1 and 2,

F ig. 4 einen Schnitt ähnlich Fig. 2 für eine abgewandelte Ausführungsform der Zahnstange,Fig. 4 shows a section similar to FIG. 2 for a modified embodiment of the rack,

Fig.5 eine Draufsicht auf das Stahlband der 2-ahnstange nach F i g. 4, sowie5 shows a plan view of the steel band of the 2-rack according to FIG. 4, as well

F i g. 6 eine Draufsicht ähnlich den F i g. 3 und 5 für eine weiter abgewandelte Ausführungsform.F i g. 6 is a plan view similar to FIGS. 3 and 5 for a further modified embodiment.

In die flexible Kunststoff-Zahnstange 10 nach den F i g. 1 und 2 ist zur Verstärkung ein Stahlband 11 eingelagert. Das Stahlband 11 weist einen Abschnitt 12 auf, der zur Teiliinie 13 der Zahnstange 10 im wesentlichen parallel verläuft. Aus dem Stahlband 11 sind Laschen 14 freigeschnitten und im wesentlichen senkrecht zum Abschnitt 12 hochgestellt. Dabei reichen in jeden der Zähne 15 der Zahnstange 10 zwei Laschen 14 hinein, die zu beiden Seiten einer Langssymmetrieebene des Stahlbandes 11 liegen. Die Zähne 15 können mit einem geradeverzahnten Ritzel kämmen.In the flexible plastic rack 10 according to FIGS. 1 and 2 is a steel band 11 for reinforcement stored. The steel strip 11 has a section 12 which is part of the line 13 of the rack 10 in runs essentially parallel. Tabs 14 are cut free from the steel strip 11 and are essentially Upright perpendicular to section 12. In this case, two tabs extend into each of the teeth 15 of the rack 10 14 into it, on both sides of a plane of long symmetry of the steel belt 11 lie. The teeth 15 can mesh with a straight-toothed pinion.

Die Fig.4 und 5 zeigen eine Ausführungsform, bei welcher jeder Zahn der Zahnstange 17 mittels einer einzigen Lasche 18 verstärkt ist, die auf der einen Seite des Stahlbandes 19 hochgestellt ist. Weitere Abwandlungen sind möglich. Beispielsweise kann entsprechend Fig.6 das Stahlband 20 beidseits mit nach oben stehenden Laschen 21 versehen sein, die wechselweise jeden zweiten Zahn verstärken. Die Zahnstange kann ferner zwei oder mehr Verzahnungen gleicher oder unterschiedlicher Teilung tragen. Zur Verstärkung der Zähne können ausgestellte Laschen eiiies oder mehrerer Stahlbänder vorgesehen sein.4 and 5 show an embodiment in which each tooth of the rack 17 by means of a single flap 18 is reinforced, which is raised on one side of the steel strip 19. Further modifications are possible. For example, in accordance with FIG. 6, the steel band 20 can be moved upwards on both sides standing tabs 21 be provided, which alternately reinforce every second tooth. The rack can also wear two or more gears of the same or different pitch. To reinforce the Teeth can have one or more flared tabs Steel bands may be provided.
