Aufgabe der Erfindung ist es eine Anlassvorrichtung für eine Brennkraftmaschine eines Kraftfahrzeugs zu schaffen, die sich durch einfache Bauweise, gute Funktion und geringes Gewicht auszeichnet.task of the invention, it is a starting device for an internal combustion engine Motor vehicle to create, which is simple design, good Function and light weight distinguishes.

Erfindungsgemäß wird dies Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.According to the invention Object achieved by the features of claim 1. Further, Features embodying the invention are contained in the subclaims.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass zum einen die Lage der Anlassvorrichtung außerhalb der Brennkraftmaschine die freie Gestaltung des Gehäuses von letzterer erleichtert und zum anderen ein funktionsgerechtes Zusammenwirken der Anlassvorrichtung mit dem Kegelrad des Kupplungsgehäuse sicherstellt. Dabei wird nicht nur die Funktion des Kupplungsgehäuses erweitert, sondern das Kegelrad in Form des Ringelements lässt sich auf einfache Weise in besagtes Kupplungsgehäuse integrieren. Schließlich wird die Aufnahme des Ringteils an der Ringwand des Kupplungsgehäuses auch durch eine axiale Ringschulter erleichtert.The with the invention mainly The advantages achieved are that, on the one hand, the location the starting device outside the internal combustion engine the free design of the housing the latter facilitates and on the other hand functional interaction the starter with the bevel gear of the clutch housing. Not only is the function of the clutch housing expanded, but the bevel gear in the form of the ring element can be easily in said clutch housing integrate. Finally the recording of the ring part on the ring wall of the clutch housing is also facilitated by an axial ring shoulder.

In der Zeichnung wird ein Ausführungsbeispiel der Erfindung gezeigt, das nachstehend näher erläutert ist.In the drawing is an embodiment shown the invention, which is explained in more detail below.

2 eine Einzelheit X der 1 in größerem Maßstab 2 a detail X of 1 on a larger scale

Eine Antriebseinheit 1 umfasst eine lediglich in Form einer Kurbelwelle 2 dargestellte Brennkraftmaschine 3, eine Kupplung 4 sowie ein Getriebe 5 und ist zum Einbau in ein nicht näher dargestelltes Kraftfahrzeug ausgebildet. Die Brennkraftmaschine 3, die Kupplung 4 und das Getriebe 5 sind miteinander verblockt, dergestalt, dass die Brennkraftmaschine 3 zwischen nicht gezeigten Radachsen, jedoch benachbart einer Hinterachse angeordnet ist – nicht offenbart –. Die Kupplung 4 ist als Mehrscheibenkupplung ausgebildet. Dabei werden Reibscheiben 6 und Reibbeläge 7 von einem rotationssymmetrischen Kupplungsgehäuse 8 umgeben, das auf einer der Brennkraftmaschine 3 zugekehrten als Schwungrad Sr dargestellten ersten Stirnseite 9 mit der Kurbelwelle 4 verbunden ist, und zwar unter Vermittlung von Schrauben 10.A drive unit 1 includes one only in the form of a crankshaft 2 illustrated internal combustion engine 3 , a clutch 4 as well as a transmission 5 and is designed for installation in a motor vehicle, not shown. The internal combustion engine 3 , the coupling 4 and the transmission 5 are interlocked with each other in such a way that the internal combustion engine 3 is arranged between wheel axles, not shown, but adjacent to a rear axle - not disclosed -. The coupling 4 is designed as a multi-disc clutch. Doing so will use friction disks 6 and friction linings 7 from a rotationally symmetrical clutch housing 8th surround that on one of the internal combustion engine 3 facing first end face shown as flywheel Sr. 9 with the crankshaft 4 is connected, with the intermediation of screws 10 ,

Um den Betrieb der Brennkraftmaschine 3 in Gang zu setzen ist eine Anlassvorrichtung 11 vorgesehen, die über ein Anlassritzel 12 mit einem Kegelrad 13 der Kupplung 4 zusammenwirkt. Das Anlassritzel 12 wird durch Radialbewegung in Eingriff mit dem Kegelrad 13 gebracht. Hierzu verläuft eine Längsachse 14 der Anlassvorrichtung 11 im rechten Winkel zu einer Längsachse 15 der Kupplung 4, jedoch liegt die Anlassvorrichtung 11 im Wesentlichen außerhalb eins Außendurchmessers Ad des Kupplungsgehäuses 8. Das Kegelrad 13 ist als ein Ringelement 16 ausgeführt, das entfernt von der ersten Stirnseite 9 an einer Ringwand 17 des Kupplungsgehäuses 8 angebracht ist, und zwar an einer zweiten Stirnseite 18. Das Ringelement 16, das getrennt vom Kupplungsgehäuse 8 hergestellt ist, ist im Bereich eines ersten Innenumfangs lue mit einer axialen Ringschulter 18 – 2 – versehen. Die Ringschulter 18 dient zur Aufnahme eines zweiten Innenumfangs luz des Kegelrads 13 bzw. des Ringelements 16. Schließlich ist das Kegelrad 13 bzw. das Ringelement 16 unter Vermittlung von Schrauben 19 an der Ringwand 17 des Kupplungsgehäuses 8 befestigt, welche Schrauben 19 sich in axialer Richtung des Kupplungsgehäuses 8 erstrecken.To operate the internal combustion engine 3 Starting is a starting device 11 provided via a starter pinion 12 with a bevel gear 13 the clutch 4 interacts. The starter pinion 12 is engaged by radial movement with the bevel gear 13 brought. A longitudinal axis runs for this 14 the starting device 11 at right angles to a longitudinal axis 15 the clutch 4 , however, the starting device is 11 essentially outside of an outer diameter Ad of the clutch housing 8th , The bevel gear 13 is as a ring element 16 executed that removed from the first face 9 on a ring wall 17 of the clutch housing 8th is attached, namely on a second end face 18 , The ring element 16 , which is separate from the clutch housing 8th is produced, is in the area of a first inner circumference lue with an axial annular shoulder 18 - 2 - Mistake. The ring shoulder 18 serves to accommodate a second inner circumference luz of the bevel gear 13 or the ring element 16 , Finally, the bevel gear 13 or the ring element 16 mediated by screws 19 on the ring wall 17 of the clutch housing 8th attached what screws 19 itself in the axial direction of the clutch housing 8th extend.
