Abstract
Description
Die Erfindung bezieht sich auf eine Zahnriemenscheibe mit einer an dieser befestigten Bordscheibe, die sich insbesondere für den Einsatz in Kraftfahrzeugen eignet.The The invention relates to a toothed belt pulley with a at this attached flanged wheel, especially for use in motor vehicles suitable.
Die Bordscheibe dient dabei dazu, ein Abwandern eines Zahnriemens auf der Riemenscheibe zu verhindern. Aus dem Stand der Technik sind hierzu unterschiedliche Maßnahmen bekannt. An einer gesinterten Zahnriemenscheibe kann zu Wegbegrenzung des Zahnriemens ein Bord mit an die Zahnriemenscheibe angesintert werden. Um ein Aufziehen des Riemens auf die Zahnriemenscheibe zu ermöglichen, kann ein solcher integraler Bord jedoch nur an einer Seite des Verzahnungsprofils der Zahnriemenscheibe vorgesehen werden. An der gegenüberliegenden Seite wird üblicherweise eine Bordscheibe montiert, die an die Zahnriemenscheibe z. B. durch Kondensatorentladungsschweißen punktförmig angeschweißt wird. Dies ist jedoch problematisch, wenn zum Zeitpunkt der Montage der Bordscheibe z. B. in der Lenkung bereits elektronische Komponenten montiert worden sind, da diese beim Schweißen beschädigt werden könnten.The Flange serves to, a drifting away of a toothed belt to prevent the pulley. From the prior art this different measures known. On a sintered timing belt pulley may lead to travel limitation of the toothed belt a board with sintered to the pulley become. To tighten the belt on the pulley too enable, However, such an integral board can only on one side of the tooth profile the toothed belt pulley are provided. At the opposite Page becomes customary a flange mounted, which is connected to the pulley z. B. by Capacitor discharge welding punctual welded becomes. However, this is problematic if at the time of installation the flanged wheel z. B. in the steering already electronic components have been mounted, since they could be damaged during welding.
Weiterhin ist allgemein bekannt, Bordscheiben durch Verschrauben oder Verklipsen zu befestigen. Der Montageaufwand hierbei ist jedoch beträchtlich. Da die Bordscheibenmontage nach der Riemenmontage erfolgt, ergeben sich bei engen räumlichen Gegebenheiten Handhabungsschwierigkeiten, die insbesondere das Anbringen von Befestigungsmitteln wie Schrauben oder Klips schwierig machen. Überdies dürfen während der Bordscheibenmontage nur begrenzte Axialkräfte aufgebracht werden.Farther is well known flanges by screwing or clipping to fix. The assembly effort here, however, is considerable. Since the flange assembly is carried out after the belt assembly, arise itself in close spatial Conditions handling difficulties, in particular the attachment make fasteners such as screws or clips difficult. moreover allowed to while the flange mounting only limited axial forces are applied.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, die Montage einer Zahnriemenscheibe im Motorraum eines Kraftfahrzeugs zu vereinfachen.From that Based on the object of the invention, the assembly a toothed belt pulley in the engine compartment of a motor vehicle to simplify.
Diese Aufgabe wird durch eine Zahnriemenscheibe gemäß Patentanspruch 1 gelöst, die sich dadurch auszeichnet, dass die Bordscheibe als im wesentlichen flache Blechscheibe mit einer Innenverzahnung ausgebildet und mit der Innenverzahnung auf die Zahnriemenscheibe aufgepresst ist.These The object is achieved by a toothed belt pulley according to claim 1, the characterized in that the flange as essentially flat sheet metal disc formed with an internal toothing and with the internal toothing is pressed onto the toothed belt pulley.
Hierbei werden keine zusätzlichen Sicherungselemente benötigt. Die axiale Montagekraft bleibt verhältnismäßig gering.in this connection will not be additional Security elements needed. The axial mounting force remains relatively low.
Zudem kann das Fügen der Bordscheibe innerhalb der Lenkungsmontage erfolgen, da Schweißverfahren, die gegebenenfalls elektronische Komponenten im Lenkgetriebe beeinträchtigen könnten, unterbleiben. Weiterhin ist zu beachten, dass bei der Montage der Bordscheibe der Zahnriemen bereits montiert und gespannt sein kann.moreover can the joining the flanged wheel within the steering assembly, since welding process, which may affect electronic components in the steering gear could remain under. Furthermore, it should be noted that during assembly of the Flange wheel of the timing belt can already be mounted and tensioned.
Überdies lässt sich die Bordscheibe kostengünstig herstellen und einfach montieren.moreover let yourself the flanged wheel cost-effective manufacture and easy to assemble.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die Zähne der Innenverzahnung gegenüber der Haupterstreckungsebene der Bordscheibe angewinkelt. Dies gewährleistet einen sicheren Sitz an der Zahnriemenscheibe. Die Innenverzahnung gleicht dabei durch die Federwirkung der Zähne Toleranzen aus, so dass die zugehörige Sitzfläche an der Zahnriemenscheibe keiner hohen Bearbeitungsgüte bedarf und bei Sinterteilen gänzlich unbearbeitet sein kann.According to one advantageous embodiment of the invention, the teeth are the Internal toothing opposite Angled the main extension plane of the flange. This ensures a secure fit on the pulley. The internal toothing compensated by the spring action of the teeth tolerances, so that the associated seat on the timing belt pulley no high quality machining required and with sintered parts entirely can be unprocessed.
Durch ein Verkrallen der Zähne im montierten Zustand kann ein zerstörungsfreies Abziehen unterbunden und gleichzeitig eine axiale und radiale Sicherung gewährleistet werden.By a clawing of the teeth in the assembled state, a nondestructive removal can be prevented while ensuring axial and radial securing become.
Weitere, vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen angegeben.Further, advantageous embodiments of the invention are specified in the claims.
Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in:following the invention with reference to an embodiment shown in the drawing explained in more detail. The Drawing shows in:
