Abstract

The wheel is provided with a hub (2) on which is shaped a pulley (17), on the external circumference of which is located a profiled section (6). In the region of the hub (2), the pulley (17) and profiled section (6) is a suitably-shaped profiled steel portion (1) extrusion-coated with a plastic jacket (3), and provided with drillings arranged over its surface. The steel portion (1) is connected to a hub ring (11) which is provided with a groove for insertion on a spring on the shaft side. To reinforce the hub (2) a support ring (5) is applied to the hub ring (11).

Description

Antriebsraddrive wheel
Die Erfindung betrifft ein Antriebsrad bei Verbrennungskraft¬ maschinen für Steuerungszwecke und geringer Kraftübertra¬ gung, bestehend aus einer Nabe mit einem daran angeformten S.cheibenteil, an dessen äußerem Umfang ein Ketten-, ein Zahnriemen- oder ein Zahnradprofil angeordnet ist.The invention relates to a drive wheel in internal combustion engines for control purposes and low power transmission, consisting of a hub with a molded disk part, on the outer circumference of which a chain, a toothed belt or a gear profile is arranged.
Derartige Antriebsräder werden insbesondere im Automobil¬ bau bei den dort verwendeten Verbrennungskraftmaschinen gebraucht, beispielsweise zum Herstellen einer Kraftüber¬ tragung von der Kurbelwelle zur Nockenwelle, aber auch sonst zu Steuerungszwecken, wobei von diesen Antriebsrä¬ dern eine geringe Kraftübertragung gefordert wird. Bisher werden solche Antriebsräder aus Kunststoff, aus Sinterme¬ tall oder aus Vollmaterial hergestellt, wobei die Nabe aus Stahl oder fließgepreßtem Aluminium besteht. Es gibt auch Konstruktionen, bei denen das ganze Teil aus wärmebestän¬ digem Kunststoff gefertigt ist. Hierbei besteht das An¬ triebsrad aus dem eigentlichen Nabenteil, an das dann ein sich in radialer Richtung erstreckendes Scheibenteil an¬ schließt, das an seinem äußeren Umfang das erforderliche Profil aufweist. Diese bekannten Ausführungen haben sich jedoch nicht bewährt, da sich der Kunststoff bei Erwärmung radial ausdehnt und damit der Umfang vergrößert wird. Bei hohen Drehzahlen erfolgt eine Vergrößerung in radialer Richtung_ noch durch die auftretenden Fliehkräfte. Der we¬ sentliche Nachteil besteht darin, daß sich das Profil desDrive wheels of this type are used in particular in automobile construction in the internal combustion engines used there, for example for producing a power transmission from the crankshaft to the camshaft, but also for other control purposes, with a low power transmission being required from these drive wheels. So far, such drive wheels have been made from plastic, from sintered metal or from solid material, the hub being made of steel or extruded aluminum. There are also constructions in which the entire part is made of heat-resistant plastic. Here, the drive wheel consists of the actual hub part, to which then adjoins a disk part extending in the radial direction, which has the required profile on its outer circumference. However, these known designs have not proven themselves since the plastic expands radially when heated and the circumference is thus enlarged. At high speeds there is an increase in the radial direction_ due to the centrifugal forces that occur. The main disadvantage is that the profile of the
ERSATZBLATT Rades verändert und somit die Genauigkeit der Kraftüber¬ tragung beeinträchtigt wird. Dazu kommen äußerst uner¬ wünschte Änderungen der Riemen- oder Kettenspannung und der Drehwinkelübertragung.REPLACEMENT LEAF Wheel changes and thus the accuracy of the power transmission is impaired. In addition there are extremely undesirable changes in the belt or chain tension and the rotation angle transmission.
Der Erfindung liegt die Aufgabe zugrunde, ein derartiges Antriebsrad so auszubilden, daß das Profil bei allen Tem¬ peraturen und Drehzahlen nahezu konstant bleibt.The invention has for its object to design such a drive wheel so that the profile remains almost constant at all temperatures and speeds.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß im Bereich der Nabe des Scheibenteiles und des Profilteils ein zusammenhängendes Metallgerippe vorgesehen ist, das allseitig mit einem Kunststoffmantel umspritzt ist.This object is achieved according to the invention in that a coherent metal frame is provided in the area of the hub of the disk part and the profile part, which is encapsulated on all sides with a plastic jacket.
Eine vorteilhafte Ausführungsform besteht darin, daß an das Metallgerippe ein Nabenring angeformt ist, der eine Nut aufweist.An advantageous embodiment is that a hub ring is formed on the metal frame, which has a groove.
Weiterhin ist es vorteilhaft, daß auf dem Nabenring ein entsprechend geformter Stützring angeordnet ist.It is also advantageous that a correspondingly shaped support ring is arranged on the hub ring.
Eine vorteilhafte Ausführungsform sieht vor, daß im Bereich der Nabe an der einen Stirnseite der mit dem Metallgerippe verbundene Nabenring eine Anlageschulter bildet und daß an der anderen Stirnseite das Metallgerippe eine Auskragung aufweist, die mit der Stirnfläche des Nabenringes bündig abschließt.An advantageous embodiment provides that in the area of the hub on one end face the hub ring connected to the metal frame forms a contact shoulder and that on the other end face the metal frame has a projection which is flush with the end face of the hub ring.
Es wird weiterhin vorgeschlagen, daß als Metallgerippe ein Stahlgerippe vorgesehen ist.It is further proposed that a steel frame is provided as the metal frame.
Schließlich wird vorgeschlagen, daß das Metallgerippe mit Bohrungen versehen ist, die bis etwa 70% der Oberfläche bedecken.Finally, it is proposed that the metal frame be provided with holes that cover up to about 70% of the surface.
Die Erfindung bringt den Vorteil, daß das Profil des RadesThe invention has the advantage that the profile of the wheel

bei den auftretenden Temperaturbelastungen sowie mechani¬ schen Belastungen nahezu unverändert bleibt, da die Deh¬ nung des Metallgerippes gegenüber der Dehnung des Kunst¬ stoffes sehr klein ist, und das Metallgerippe^ den Kunst¬ stoff an der Dehnung hindert. Hierbei läßt sich auch die Nabe besonders vorteilhaft ausbilden, so daß eine gute kraftschlüssige Verbindung mit der Welle gewährleistet ist, wobei die axiale Anpreßkraft verbessert wird.with the occurring thermal and mechanical loads remains almost unchanged, since the expansion of the metal frame is very small compared to the expansion of the plastic, and the metal structure prevents the plastic from expanding. Here, the hub can also be designed particularly advantageously, so that a good non-positive connection with the shaft is ensured, the axial contact force being improved.
Die Erfindung wird in der nachfolgenden Beschreibung an¬ hand von in der Zeichnung dargestellten Ausführu'ngsbei- spielen näher erläutert.The invention is explained in more detail in the following description with reference to exemplary embodiments shown in the drawing.
