Abstract

Diese Hubkolbenbrennkraftmaschine ist mit einer schwingungsdämpfenden Ausgleichswelle versehen, die in einem Lagergehäuse drehbar gelagert ist. Das Lagergehäuse ist mittels einer Schraubverbindung am Zylinderkurbelgehäuse befestigt. Damit die Rotationskräfte der Ausgleichswelle zwischen Lagergehäuse und Zylindergehäuse spielfrei abgestützt werden, weist wenigstens eine Schraube der Schraubverbindung einen kegelförmigen Ansatz auf, der mit einer korrespondierenden Anfasung im Lagergehäuse zusammenwirkt.This reciprocating internal combustion engine is provided with a vibration-damping balance shaft, which is rotatably mounted in a bearing housing. The bearing housing is attached to the cylinder crankcase by means of a screw connection. So that the rotational forces of the balance shaft between the bearing housing and the cylinder housing are supported without play, at least one screw of the screw connection has a conical projection which interacts with a corresponding chamfer in the bearing housing.

Description

Die Erfindung betrifft eine Hubkolbenbrennkraftmaschine, vorzugsweise vierzylindriger Bauart, mit zumindest einer schwingungsdämpfenden Ausgleichswelle, die in einem an einem Kurbelgehäuse mittels einer Schraubverbindung gehaltenen Lagergehäuse drehbar gelagert ist.The invention relates to a reciprocating piston internal combustion engine, preferably a four-cylinder type, with at least one vibration-damping balance shaft, which is rotatably mounted in a bearing housing held on a crankcase by means of a screw connection.

Es wurde durch eine nicht veröffentlichte schwedische Patentanmeldung bereits vorgeschlagen, das Lagergehäuse der Ausgleichswelle mittels normaler, hauptsächlich in axialer Richtung wirkender Schrauben zu verbinden. Solche Schrauben sind zur Befestigung des Lagergehäuses der Ausgleichswelle nicht geeignet, da an ihnen keine Vorkehrungen getroffen sind, um die insbesondere im oberen Drehzahlbereich auftretenden, quer zur Schraubenachse wirkenden Kräfte abzustützen.It has already been proposed by an unpublished Swedish patent application to connect the bearing housing of the balance shaft by means of normal screws, which mainly act in the axial direction. Such screws are not suitable for fastening the bearing housing of the balancer shaft, since no precautions have been taken to support the forces that occur in the upper speed range and act transversely to the screw axis.

Gemäß einem weiteren Vorschlag der besagten schwedischen Patentanmeldung soll eine Abstützung zwischen Lagergehäuse und Kurbelgehäuse dadurch erreicht werden, daß Wangen des Lagergehäuses sich an Wandungen einer Ausnehmung im Kurbelgehäuse abstützen. Hierbei ist nicht nur der hohe Fertigungsaufwand für die Wangen und die Ausnehmung nachteilig, sondern eine, wirksame Querkraftabstützung ist aufgrund von nicht zu vermeidenden Herstellungstoleranzen schwerlich realisierbar.According to a further proposal of said Swedish patent application, support between the bearing housing and the crankcase is to be achieved in that the cheeks of the bearing housing are supported on walls of a recess in the crankcase. Not only is the high manufacturing outlay for the cheeks and the recess disadvantageous, but effective shear force support is difficult to achieve due to the unavoidable manufacturing tolerances.

Aufgabe der Erfindung ist es, das Lagegehäuse der Ausgleichswelle am Kurbelgehäuse so zu befestigen, daß unter Vermeidung aufwendiger fertigungstechnischer Maßnahmen die rotierenden Massenkräfte funktionsgerecht abgestützt werden.The object of the invention is to attach the position housing of the balancer shaft to the crankcase in such a way that the rotating inertial forces are supported in a functional manner while avoiding complex manufacturing measures.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst. Weitere, die Erfindung in vorteilhafter Weise ausgestaltenden Merkmale sind in den nachfolgenden Ansprüchen enthalten.According to the invention, this object is achieved by the features of the characterizing part of claim 1. Further features that advantageously design the invention are contained in the following claims.

Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, daß der kegelförmige Ansatz der Schraube bzw. der Schraubenmutter und die Anfasung am Lagergehäuse die auftretenden, quer zur Schraubenachse wirkenden Kräfte funktionsgerecht abstützen. Die Stiftschraube weist zur Abstützung einen mit einer Anfasung des Kurbelgehäuses zusammenarbeitenden kegelförmigen Ansatz auf, wodurch Kerbwirkungen vom Gewindezapfen der Stiftschraube ferngehalten werden.The main advantages achieved with the invention are the fact that the conical approach of the screw or the nut and the chamfer on the bearing housing support the occurring forces acting transversely to the screw axis in a functional manner. The stud screw has a conical projection which cooperates with a chamfer on the crankcase for support, as a result of which notch effects are kept away from the threaded stud of the stud screw.

  • 1 shows a partial cross section of a reciprocating piston internal combustion engine with the screw connection according to the invention,
  • 2 is a partial view of FIG. 1 on a larger scale and with another embodiment,
  • 3 shows a section along the line III-III of FIG. 1st

Eine Hubkolbenbrennkraftmaschine 1 umfasst ein Zylinderkurbelgehäuse 2, an dessen Längsseite 3 sich eine Ausgleichswelle 4 erstreckt, die zur Schwingungsdämpfung (Massenkräfte, Gaskräfte) dient.A reciprocating piston internal combustion engine 1 comprises a cylinder crankcase 2, on the longitudinal side 3 of which a balancer shaft 4 extends, which is used for vibration damping (inertial forces, gas forces).

Die Ausgleichswelle 4 weist Ausgleichsgewichte 5, 6 auf, und dreht sich mit doppelter Kurbelwellendrehzahl in einem Lagergehäuse 7, das durch zwei Gehäusehälften 8, 9 gebildet wird. Die Gehäusehälften 8, 9 werden mittels Schrauben 10, 11 in Lage gehalten.The balance shaft 4 has balance weights 5, 6, and rotates at double crankshaft speed in a bearing housing 7, which is formed by two housing halves 8, 9. The housing halves 8, 9 are held in position by means of screws 10, 11.

Die Halterung des Lagergehäuses 7 erfolgt ebenfalls mittels im Abstand zueinander angeordneter Schrauben 12, 13, die bei 14 und 15 (Fig. 3) vorgesehen sind, Am Zylinderkurbelgehäuse 2 sind zur Aufnahme des Lagergehäuses 7 Befestigungsabschnitte 16, 17 angebracht.The bearing housing 7 is also held by means of screws 12, 13 which are arranged at a distance from one another at 14 and 15 (Fig. 3) are provided, 7 mounting portions 16, 17 are attached to the cylinder crankcase 2 for receiving the bearing housing.

Die Schraube 12 (bei 14) sowie die nicht dargestellten Schrauben bei 15 werden durch übliche Sechskantschrauben gebildet. Demgegenüber weist die Schraube 13 einen kegelförmigen Ansatz 18 auf, der mit einer korrespondierenden Anfasung 19 des Lagergehäuses 7 zusammenwirkt, dergestalt, daß die auftretenden, quer zur Längsachse A-A der Schraube 13 wirkenden Kräfte spielfrei abgestützt werden. Um Uberbestimmungen zu vermeiden, genügt es lediglich eine Schraube auf diese Weise auszubilden.The screw 12 (at 14) and the screws, not shown, at 15 are formed by conventional hexagon screws. In contrast, the screw 13 has a conical projection 18 which cooperates with a corresponding chamfer 19 of the bearing housing 7 in such a way that the forces which occur transversely to the longitudinal axis A-A of the screw 13 are supported without play. To avoid over-determinations, it is sufficient to form a screw in this way.

Die Schraube 13 besitzt einen in eine Gewindebohrung 20 ragenden Gewindezapfen 21 und einen Kopf 22, der über eine Ausnehmung 23 im Lagergehäuse 7 zugänglich ist.The screw 13 has a threaded pin 21 projecting into a threaded bore 20 and a head 22 which is accessible via a recess 23 in the bearing housing 7.

Gemäß Fig. 2 wird die Schraube durch eine Stiftschraube 24 gebildet, deren Gewindezapfen 25 in eine Gewindebohrung 26 eingedreht ist. Der Gewindezapfen 25 stützt sich mittels eines kegelförmigen Ansatzes 27 an einer korrespondierenden Anfasung 28 des Zylinderkurbelgehäuses 2 ab, wodurch auf den Gewindezapfen 23 einwirkende Kräfte abgestützt werden.2, the screw is formed by a stud 24, the threaded pin 25 is screwed into a threaded bore 26. The threaded stem 25 is supported by means of a cone-shaped projection 27 on a corresponding A nfasung 28 from the cylinder crankcase 2, thereby acting forces 23 are supported on the threaded pin.

Eine Schraubenmutter 29 der Stiftschraube 22 weist einen kegelförmigen Ansatz 30 auf, der mit einer korrespondierenden Anfasung 31 des Lagergehäuses 7 zusammenwirkt. Die Schraubenmutter 29 ist über eine Ausnehmung 32 im Lagergehäuse 7 zugänglich.A screw nut 29 of the stud screw 22 has a conical projection 30 which interacts with a corresponding chamfer 31 of the bearing housing 7. The screw nut 29 is accessible via a recess 32 in the bearing housing 7.
