Description

Brennkraftmaschine Internal combustion engine
Die Erfindung betrifft ein Kurbelgehäuse mit einem Kurbelwellenraum, in welchem eine Kurbelwelle angeordnet ist, mit einem stirnseitigen Lagerenddeckel zur Lagerung der Kurbelwelle, welcher aus einem Lageroberteil sowie einem Lagerunterteil komplettiert ist, mit einem stirnseitigen Rädertrieb zum Antreiben eines Nebenaggregats, umfassend ein erstes Antriebsrad auf der Kurbelwelle, ein zweites Antriebsrad am Nebenaggregat und ein Zwischenrad, welches mit dem ersten und zweiten Antriebsrad kämt.The invention relates to a crankcase with a crankshaft space, in which a crankshaft is arranged, with a front end Lagerenddeckel for supporting the crankshaft, which is completed by a bearing shell and a bearing base, with a front wheel drive for driving an accessory comprising a first drive wheel on the Crankshaft, a second drive wheel on the accessory and an idler, which kämme with the first and second drive.
Bei einer Brennkraftmaschine befindet sich auf der Kraftgegenseite der Antrieb für die Nebenaggregate, zum Beispiel öl- und Wasserpumpe. Ausgeführt wird der Antrieb als stirnseitiger Rädertrieb, welcher ein erstes Antriebsrad auf der Kurbelwelle, ein zweites Antriebsrad auf dem Nebenaggregat und ein Zwischenrad umfasst. Im Bereich der Lagerstelle des Zwischenrads befindet sich der Kurbelwellenraum, so dass hier keine Befestigungsmöglichkeit für die Lagerstelle oder nur eine ungenügende Kurbelgehäuse- Wandstärke vorhanden ist. Gelöst wird dieses Problem, indem das Zwischenrad mit Lagerstelle zwischen einer ersten und einer zweiten Halteplatte angeordnet sind und eine Trägereinheit bilden. Eine derartige Lösung ist aus der DE 199 60 130 A1 bekannt. Diese Trägereinheit liegt stirnseitig am Kurbelgehäuse an und ist mit dem Lageroberteil (obere Lagerbrücke) verschraubt. Auf Grund des sehr komplexen Aufbaus ist die Trägereinheit schwingungsempfindlich, so dass ein hydraulisches Spielausgleichselement als Dämpfung zwingend erforderlich ist.In an internal combustion engine is located on the opposite side of the power drive for the ancillaries, for example, oil and water pump. The drive is designed as an end-face wheel drive, which comprises a first drive wheel on the crankshaft, a second drive wheel on the auxiliary unit and an intermediate wheel. In the area of the bearing point of the intermediate wheel is the crankshaft space, so that there is no possibility of attachment for the bearing or only insufficient crankcase wall thickness exists. This problem is solved by the intermediate wheel with bearing between a first and a second holding plate are arranged and form a carrier unit. Such a solution is known from DE 199 60 130 A1. This carrier unit is located on the front side of the crankcase and is bolted to the upper bearing part (upper bearing bridge). Due to the very complex structure, the carrier unit is sensitive to vibration, so that a hydraulic clearance compensation element as damping is absolutely necessary.
Eine einfachere Ausführungsform ist aus der DE 100 02 538 A1 bekannt. Bei dieser ist das Zwischenrad über einen Haltezapfen auf einer länglichen Halteplatte angeordnet. Befestigt ist die Halteplatte am Kurbelgehäuse über zwei Verbindungsstellen, wobei nach der Montage sich das Zwischenrad zwischen der Gehäusewandung und der Halteplatte befindet. Die Verbindungsstellen wiederum liegen auf der Symmetrieachse des Zwischenrads, welche senkrecht zur Drehachse ist. Über eine Einrichtung zum Beaufschlagen der Halteplatte mit Vorspannkraft werden die Antriebsräder und das Zwischenrad in korrektem Eingriff gehalten. Bauartbedingt lässt sich diese Lösung nicht nahe des Kurbelwellenraums verwenden. Da die Halteplatte im Betrieb durch die wechselnde Last der Antriebsräder und des Zwischenrads auf Biegung beansprucht wird, muss die Halteplatte massiv ausgeführt sein.A simpler embodiment is known from DE 100 02 538 A1. In this, the intermediate wheel is arranged via a retaining pin on an elongate retaining plate. Attached is the retaining plate on the crankcase via two connection points, wherein after assembly, the intermediate wheel between the housing wall and the retaining plate is located. The connection points in turn lie on the symmetry axis of the Zwischenrads, which is perpendicular to the axis of rotation. About a means for biasing the holding plate with biasing force, the drive wheels and the intermediate gear are held in correct engagement. Due to the design, this solution can not be used close to the crankshaft space. Since the holding plate is subjected to bending during operation by the changing load of the drive wheels and the intermediate wheel, the holding plate must be solid.
Der Erfindung liegt die Aufgabe zu Grunde, für ein Kurbelgehäuse einen einfachen stirnseitigen Rädertrieb zu entwerfen.The invention is based on the object to design a simple front wheel drive for a crankcase.
Gelöst wird die Aufgabe durch ein Kurbelgehäuse mit einem Kurbelwellenraum, in welchem eine Kurbelwelle angeordnet ist, mit einem stirnseitigen Lagerenddeckel zur Lagerung der Kurbelwelle, welcher aus einem Lageroberteil sowie einem Lagerunterteil komplettiert ist, mit einem stirnseitigen Rädertrieb zum Antreiben eines Nebenaggregats, umfassend ein erstes Antriebsrad auf der Kurbelwelle, ein zweites Antriebsrad am Nebenaggregat und ein Zwischenrad, welches mit dem ersten und zweiten Antriebsrad kämt. Ferner umfasst die Lösung eine Halteplatte zur Lagerung des Zwischenrads, welche mit dem Kurbelgehäuse, dem Lageroberteil und mit dem Lagerunterteil verschraubt ist. Durch die zusätzlichen Verschraubungspunkte der Halteplatte, insbesondere am Lagerunterteil, werden die freie Biegelänge und damit die Biegemomente auf die Halteplatte verkleinert. Die hohe Stabilität wiederum erlaubt es, dass die Halteplatte mit entsprechendem Gewichtsvorteil dünner ausgeführt werden kann. Zusätzliche Dämpfungsmaßnahmen, wie etwa hydraulische Ausgleichselemente, sind nicht erforderlich. Insgesamt ist die Halteplatte einfach und kostengünstig in der Ausführung.The object is achieved by a crankcase with a crankshaft space in which a crankshaft is arranged, with a front end Lagerenddeckel for supporting the crankshaft, which is completed by a bearing shell and a bearing base, with a front wheel drive for driving an accessory comprising a first drive wheel on the crankshaft, a second drive wheel on the accessory and an idler, which kämme with the first and second drive. Furthermore, the solution comprises a holding plate for supporting the intermediate gear, which is bolted to the crankcase, the bearing shell and the bearing base. Due to the additional screwing points of the retaining plate, in particular on the lower part of the bearing, the free bending length and thus the bending moments on the retaining plate are reduced. The high stability, in turn, allows the holding plate to be made thinner with a corresponding weight advantage. Additional damping measures, such as hydraulic compensating elements, are not required. Overall, the retaining plate is simple and inexpensive in design.
Die Halteplatte und eine Haltezapfen, auf dem das Zwischenrad drehbar gelagert ist, sind einstückig miteinander ausgeführt. Bei einem Kurbelgehäuse mit Nebenaggregaten auf der A- und der B-Seite ist dann jeweils eine entsprechende Halteplatte vorgesehen.The holding plate and a retaining pin on which the intermediate wheel is rotatably mounted, are integrally formed with each other. In a crankcase with ancillaries on the A- and B-side then a respective retaining plate is provided.
In den Figuren ist ein bevorzugtes Ausführungsbeispiel dargestellt. Es zeigen:In the figures, a preferred embodiment is shown. Show it:
Figur 1 ein Kurbelgehäuse mit Blick von der Kraftgegenseite und Figur 2 ein Schnittbild entlang der Linie AA aus Figur 1. Die Figur 1 zeigt ein Kurbelgehäuse 1 einer Brennkraftmaschine in V-Anordnung mit Blick von der Kraftgegenseite auf eine Stirnseite 3 des Kurbelgehäuses 1. Die weitere Beschreibung erfolgt gemeinsam mit der Figur 2, welche ein Schnittbild entlang der Linie AA in der Figur 1 zeigt. Die Kraftgegenseite liegt der Kraftseite gegenüber. Die Kraftseite wiederum ist bei einer Brennkraftmaschine diejenige Seite, an welcher das Antriebsmoment, zum Beispiel von einem Getriebe, abgenommen wird. An der Unterseite wird das Kurbelgehäuse 1 durch eine Bodenplatte 12 gegenüber der Umwelt öldicht verschlossen. Die Bodenplatte 12 ist in der Figur 1 nur andeutungsweise dargestellt.1 shows a crankcase with a view from the opposite side of the force and Figure 2 is a sectional view taken along the line AA of Figure 1. 1 shows a crankcase 1 of an internal combustion engine in a V-arrangement with a view from the opposite side of the force on a front side 3 of the crankcase 1. The further description is made together with Figure 2, which shows a sectional view along the line AA in Figure 1. The opposite side of the force is opposite to the force side. The force side in turn is in an internal combustion engine that side on which the drive torque, for example, from a transmission, is removed. At the bottom, the crankcase 1 is closed by a bottom plate 12 against the environment oil-tight. The bottom plate 12 is shown only schematically in FIG.
Integraler Bestandteil des Kurbelgehäuses 1 ist ein Kurbelwellenraum 2, in welchem sich eine Kurbelwelle befindet. Gelagert ist die Kurbelwelle in einem Lagerenddeckel, welcher aus einem Lageroberteil 4 und einem Lagerunterteil 5 gebildet wird, siehe Figur 1. Das Lagerunterteil 5 und das Lageroberteil 4 sind im Kurbelgehäuse 1 über Zugankerschrauben 13 fixiert. Am Kurbelgehäuse 1 ist an der Stirnseite 3 ein Rädertrieb 6 angeordnet. Über den Rädertrieb 6 wird ein Nebenaggregat angetrieben, zum Beispiel eine Hochdruckpumpe HDP zur Förderung von Kraftstoff in ein Rail bei einem Common-Railsystem. Die Hochdruckpumpe HDP ist auf der B-Seite des Kurbelgehäuses 1 angeordnet. Der Rädertrieb 6 umfasst ein erstes Antriebsrad 7, welches auf der Kurbelwelle befestigt ist, ein Zwischenrad 9 und ein zweites Antriebsrad 8, welches die Hochdruckpumpe HDP antreibt. Das Antriebsrad 8 ist in der Figur 1 nur teilweise dargestellt. Gelagert ist das Zwischenrad 9 über einen Haltezapfen 11 auf einer Halteplatte 10, siehe Figur 2. Die Halteplatte 10 und der Haltezapfen 11 sind einstückig ausgeführt. Fixiert ist die Halteplatte 10 über vier Schrauben. Über eine erste Schraube 14 ist die Halteplatte 10 am Lageroberteil 4 befestigt. Über eine zweite Schraube 15 und eine dritte Schraube 16 ist die Halteplatte 10 am Kurbelgehäuse 1 verschraubt. Über eine vierte Schraube 17 ist die Halteplatte 10 am Lagerunterteil 5 fixiert, welches eine Anlagefläche hierfür aufweist. Durch die zusätzlichen Verschraubungspunkte der Halteplatte 10, insbesondere am Lagerunterteil 5 und am Lageroberteil 4, werden die freie Biegelänge und damit die Biegemomente verkleinert. Die hohe Stabilität wiederum erlaubt es, dass die Halteplatte mit entsprechendem Gewichtsvorteil dünner ausgeführt werden kann, zum Beispiel aus Stahl. Wie aus der Figur 2 ersichtlich ist, ist der Rädertrieb 6 auf der Stirnseite 3 offen. Sind sowohl auf der A-Seite des Kurbelgehäuses 1 als auch auf der B-Seite des Kurbelgehäuses 1 ein Nebenaggregat angeordnet, so sind entsprechend zwei Rädertriebe 6 vorhanden. In der Figur 1 ist das Nebenaggregat auf der A-Seite beispielsweise eine Wasserpumpe WP. Der Rädertrieb, das Zwischenrad, die Halteplatte und deren Befestigungspunkte auf der A-Seite sind identisch zum vorher beschriebenen Rädertrieb auf der B-Seite. Integral part of the crankcase 1 is a crankshaft space 2, in which there is a crankshaft. The crankshaft is mounted in a bearing end cover, which is formed from an upper bearing part 4 and a lower bearing part 5, see FIG. 1. The lower bearing part 5 and the upper bearing part 4 are fixed in the crankcase 1 by tie bolt bolts 13. On the crankcase 1, a gear drive 6 is arranged on the front side 3. Via the gear drive 6, an auxiliary unit is driven, for example a high-pressure pump HDP for conveying fuel into a rail in a common rail system. The high pressure pump HDP is disposed on the B side of the crankcase 1. The gear drive 6 comprises a first drive wheel 7, which is mounted on the crankshaft, an intermediate gear 9 and a second drive wheel 8, which drives the high-pressure pump HDP. The drive wheel 8 is shown only partially in FIG. The idler gear 9 is supported via a retaining pin 11 on a retaining plate 10, see FIG. 2. The retaining plate 10 and the retaining pin 11 are made in one piece. The holding plate 10 is fixed by four screws. Via a first screw 14, the holding plate 10 is fixed to the bearing upper part 4. Via a second screw 15 and a third screw 16, the retaining plate 10 is screwed to the crankcase 1. About a fourth screw 17, the holding plate 10 is fixed to the bearing base 5, which has a bearing surface for this purpose. Due to the additional screwing points of the holding plate 10, in particular on the bearing base 5 and on the upper bearing part 4, the free bending length and thus the bending moments are reduced. The high stability, in turn, makes it possible for the holding plate to be made thinner with a corresponding weight advantage, for example made of steel. As can be seen from FIG. 2, the wheel drive 6 is open on the end face 3. If an auxiliary unit is arranged both on the A-side of the crankcase 1 and on the B-side of the crankcase 1, two gear drives 6 are correspondingly present. In the figure 1, the accessory on the A-side, for example, a water pump WP. The gear drive, the intermediate wheel, the retaining plate and their attachment points on the A-side are identical to the previously described wheel drive on the B-side.
