Abstract

The crankshaft (1) has a toothed wheel (3) on which a defined number of teeth are periodically machine dynamically loaded less; these teeth (4) have a different profile from the remaining teeth (5) so that the toothed wheel or toothed rim acts as a pulse wheel for triggering an adjacent sensor (7). The height and/or width of the less loaded teeth is reduced. Independent claims are also included for the following: a gear wheel.

Description

Die Erfindung bezieht sich nach dem Oberbegriff des Patentanspruches 1 auf eine Brennkraftmaschinen-Kurbelwelle mit einem Zahnrad, bei dem eine bestimmte An­ zahl Zähne periodisch maschinendynamisch geringer belastet sind.The invention relates to a preamble of claim 1 Internal combustion engine crankshaft with a gear in which a certain type number of teeth are periodically less mechanically loaded.

Eine derartige Kurbelwelle ist beispielsweise aus der DE 40 10 856 A1 bekannt, wobei ein mit einer Kurbelwange drehfest verbundener Zahnkranz zum Antrieb von Ausgleichswellen dient. Bei Motorradmotoren dient ein derartiges Zahnrad bekannt­ lich der Primärübertragung auf einen Getriebeeingang.Such a crankshaft is known for example from DE 40 10 856 A1, wherein a sprocket rotatably connected to a crank arm for driving Balancing shafts is used. Such a gear is known for motorcycle engines Lich the primary transmission to a transmission input.

Weiter ist aus der DE 43 09 245 C2 eine Kurbelwelle mit einem montierbar ange­ ordneten Zahnkranz bekannt, der neben seiner Ausgestaltung als zusätzliches Aus­ gleichsgewicht auch als Impulsring in Verbindung mit einem zugeordneten Sensor zur Erkennung einer Kurbelwellen-Winkelposition dient.Furthermore, from DE 43 09 245 C2 a crankshaft with a mountable is attached arranged known ring gear, which in addition to its design as an additional off Equilibrium also as an impulse ring in connection with an assigned sensor serves to detect a crankshaft angular position.

Schließlich ist aus der europäischen Patentanmeldung EO 0 341 398 A2 ein durch die Ausgestaltung als Blechstanzring massenreduzierter Impulsring bekannt.Finally, from the European patent application EO 0 341 398 A2 the design as a stamped sheet metal ring with reduced mass is known.

Es ist üblich, die Verzahnungen der eingangs genannten Zahnräder auf ein Grund­ drehmoment mit überlagten dynamischen Anteilen auszulegen, wobei diese dynamischen Anteile je nach Bauart der Brennkraftmaschine phasenbezogen auftreten mit der Folge, dass eine bestimmte Anzahl Zähne periodisch maschinendynamisch geringer belastet sind.It is common to base the toothing of the gears mentioned at the beginning to design torque with superimposed dynamic components, these dynamic  Depending on the design of the internal combustion engine, parts occur phase-related with the result that a certain number of teeth periodically machine dynamic are less polluted.

Ausgehend von dieser Erkenntnis ist es Aufgabe der Erfindung, ein derart be­ anspruchtes Zahnrad als Impulsrad auszubilden.Based on this finding, it is an object of the invention to be such trained gear as a pulse wheel.

Diese Aufgabe ist mit dem Patentanspruch 1 dadurch gelöst, dass die geringer be­ lasteten Zähne in ihrer Kontur von der der übrigen Zähne derart abweichend ge­ staltet sind, dass das Zahnrad als Impulsrad zur Triggerung eines benachbart ange­ ordneten Sensors dient.This object is achieved with claim 1 in that the lower be burdened teeth in their contour so different from that of the other teeth ge stalten that the gear as a pulse wheel for triggering an adjacent assigned sensor is used.

Mit der Erfindung kann in vorteilhafter Weise ein separates Impulsrad entfallen, wo­ mit auch Kosten und Gewicht reduziert sind.With the invention, a separate pulse wheel can advantageously be omitted where with reduced costs and weight.

Weitere Ausgestaltungen der Erfindung sind in Unteransprüchen beschrieben.Further refinements of the invention are described in the subclaims.

Die Erfindung ist anhand eines in der Zeichnung schematisch dargestellten Aus­ führungsbeispiels beschrieben.The invention is based on a schematically shown in the drawing management example described.

Eine nicht dargestellte Brennkraftmaschine umfasst eine abschnittsweise dar­ gestellte Kurbelwelle 1 mit einem abschnittsweise, perspektivisch dargestellten Zahnkranz 2 für ein Zahnrad 3, bei dem eine bestimmte Anzahl Zähne 4 periodisch maschinendynamisch geringer belastet sind.An internal combustion engine, not shown, comprises a crankshaft 1 , shown in sections, with a toothed ring 2 , shown in sections, in perspective, for a gearwheel 3 , in which a certain number of teeth 4 are periodically less stressed by machine dynamics.

Zur erfindungsgemäßen Ausbildung des Zahnkranzes 2 bzw. des Zahnrades 3 als Impulsrad 6 wird vorgeschlagen, dass die geringer belasteten Zähne 4 in ihrer Kon­ tur von der der übrigen Zähne 5 derart abweichend gestaltet sind, dass das Zahnrad 3 bzw. der Zahnkranz 2 als Impulsrad 6 zur Triggerung eines benachbart angeord­ neten Sensors 7 dient. For the inventive design of the ring gear 2 or the gear 3 as a pulse wheel 6 , it is proposed that the less loaded teeth 4 in their con struct from those of the other teeth 5 are designed so that the gear 3 or the ring gear 2 as a pulse wheel 6th serves to trigger an adjacent sensor 7 .

In einer ersten Ausgestaltung der Erfindung ist die Höhe der geringer belasteten Zähne 4 reduziert.In a first embodiment of the invention, the height of the less loaded teeth 4 is reduced.

In einer anderen, bevorzugten Ausgestaltung ist die Breite der geringer belasteten Zähne 4 reduziert.In another preferred embodiment, the width of the teeth 4 which are less loaded is reduced.

Schließlich ist es auch möglich, dass die geringer belasteten Zähne 4 in Höhe und Breite reduziert sind.Finally, it is also possible for the teeth 4 , which are less loaded, to be reduced in height and width.

Eine vorteilhafte Ausgestaltung ergibt sich ferner dadurch, wenn das mit der Kur­ belwelle 1 drehfest verbundene Zahnrad 3 mittels eines auf einer Kurbelwange 8 der Kurbelwelle 1 angeordneten Zahnkranz 2 gebildet ist.An advantageous embodiment also results from the fact that the gearwheel 3, which is connected in a rotationally fixed manner to the cure 1 , is formed by means of a toothed ring 2 arranged on a crank arm 8 of the crankshaft 1 .
