Abstract

In order to reduce the noise emissions of V-type reciprocating-piston machines, in particular internal combustion engines, with transverse screws (8) between the engine block (1) and the main bearing caps (6) fastened to the engine block (1) by vertical main-bearing bolts (7) in the region of a skirt (9) of the engine block (1) for the lateral support of the main bearing caps (6), the engine block (1) has, in the region of the main bearings (3), extensions (11) of the main bearing wall on both sides of the longitudinal plane (16) extending in the direction of the engine vertical axis (Z), said extensions being formed within the skirt in the direction of the oil sump. The main bearing caps (6) are attached between these extensions and the transverse screws (8) seated in the main bearing caps (6) pass through them. In this arrangement, the skirt (9) is arranged at a distance from the extensions (11) of the main bearing wall which serves for the formation of the clearance (12) between the transverse screws (8) and the inside (9') of the skirt (9). <IMAGE>

Description

Die Erfindung betrifft eine Hubkolbenmaschine, insbesondere Brennkraftmaschine mit V-förmiger Anordnung der Zylinder oder Zylinderreihen, mit Querschrauben zwischen Motorblock und den mit Hauptlagerhochschrauben am Motorblock befestigten Hauptlagerbügeln im Bereich einer Schürze des Motorblocks zur seitlichen Abstützung der Hauptlagerbügel, sowie mit einer Ölwanne.The invention relates to a reciprocating piston engine, in particular an internal combustion engine with a V-shaped arrangement of the cylinders or rows of cylinders, with transverse screws between the engine block and the main bearing brackets attached to the engine block with main bearing high screws in the region of an apron of the engine block for lateral support of the main bearing bracket, and with an oil pan.

Bei derartigen Hubkolbenmaschinen ist infolge der zur Hoch-und damit Hauptverschraubungsrichtung der Hauptlagerbügel geneigt einwirkenden Lagerkräfte im allgemeinen eine seitliche Abstützung der Hauptlagerbügel notwendig. Aus diesem Grund sind bekannte Lagereinbindungen mit zusätzlichen Querschrauben zwischen Motorblock und Hauptlagerbügel versehen.In such reciprocating piston machines, a lateral support of the main bearing bracket is generally necessary as a result of the bearing forces acting at an angle to the upward and thus main screwing direction of the main bearing bracket. For this reason, known mountings are provided with additional transverse screws between the engine block and the main bracket.

Es sind Hubkolbenmaschinen der eingangs genannten Art bekannt, deren Querverschraubung im Winkel von etwa 90° in Richtung zur Lagerhauptverschraubung ausgeführt sind, siehe z.B. DE-OS 35 42 135. Die Verwendung von Querschrauben gestattet zwar eine gute seitliche Abstützung der Lagerkräfte, es tritt aber durch die steife Verbindung mit der Schürze des Motorblocks eine erhöhte Schwingungseinleitung in das Motorgehäuse ein, da die Geräuschanregung vornehmlich über den Weg KolbenPleuelstange - Kurbelwelle - Hauptlager - Schürze erfolgt. Insbesondere werden alle Schwingungen der Hauptlagerwände bzw. -bügel durch die steife seitliche Einbindung in die Schürze fast ungedämpft übertragen. Dies betrifft sowohl die Biege-und Torsionsschwingungen als auch die Ovalverformungen der Lagerbohrung selbst unter den Lagerkräften. Eine verstärkte Anregung der Schürze in Motorquerrichtung ist auch deswegen besonders nachteilig, da die an der Schürze befestigte Ölwanne in Art einer Fußpunkterregung mit angeregt wird. Die Ölwanne dominiert sogar oft die Gesamtabstrahlung von Verbrennungsmotoren; daher kann sich die Schürzen- und damit Ölwannenanregung auch auf die Stärke des Gesamtgeräusches auswirken.Reciprocating piston machines of the type mentioned at the outset are known, the transverse screw connection of which is carried out at an angle of approximately 90 ° in the direction of the main bearing screw connection, see e.g. DE-OS 35 42 135. The use of transverse screws allows good lateral support of the bearing forces, but due to the rigid connection to the apron of the engine block, increased vibration is introduced into the engine housing, since the noise excitation occurs primarily via the piston connecting rod - crankshaft - Main bearing - apron is made. In particular, all vibrations of the main bearing walls or brackets are transmitted almost undamped due to the rigid lateral integration in the skirt. This affects both the bending and torsional vibrations as well as the oval deformations of the bearing bore itself under the bearing forces. Increased excitation of the apron in the transverse direction of the engine is also particularly disadvantageous because the oil pan attached to the apron is also excited in the manner of a foot excitation. The oil pan often even dominates the overall radiation from internal combustion engines; therefore the apron and thus oil pan excitation can also affect the strength of the overall noise.

Aufgabe der Erfindung ist, diese Nachteile zu vermeiden, und eine Hubkolbenmaschine zu schaffen, bei der die infolge der Verwendung der Querverschraubung verstärkte Schwingungsanregung der Schürze und die Mitanregung der Ölwanne vermieden werden.The object of the invention is to avoid these disadvantages, and to provide a reciprocating machine in which the result of Using the transverse screw connection, increased vibration excitation of the apron and the co-excitation of the oil pan can be avoided.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß der Motorblock im Bereich der Hauptlager zu beiden Seiten der in Richtung Motorhochachse weisenden Längsebene innerhalb der Schürze in Richtung der Ölwanne ausgebildete Verlängerungen der Hauptlagerwand aufweist, zwischen welchen die Hauptlagerbügel angebracht sind und die von den in den Hauptlagerbügeln sitzenden Querschrauben durchsetzt sind, und daß die Schürze in einem zur Bildung einer Freistellung zwischen den Querschrauben und der Innenseite der Schürze dienendem bestand von den Verlängerungen der Hauptlagerwand angeordnet ist.The solution to this problem according to the invention is that the engine block in the area of the main bearings on both sides of the longitudinal plane pointing in the direction of the engine vertical axis within the skirt in the direction of the oil pan has extensions of the main bearing wall, between which the main bearing brackets are attached and of which in the main bearing brackets seated transverse screws are interspersed, and that the skirt is arranged in a serving to form an exemption between the transverse screws and the inside of the skirt from the extensions of the main bearing wall.

Vorzugsweise ist der Motorblock so gestaltet, daß die Schürze die Bohrungen der Querschrauben überdeckt und zum Bedienen der Querschrauben in der Schürze Öffnungen vorgesehen sind, die gegen Ölaustritt mit Verschlußdeckeln oder Verschlußschrauben od. dgl. öldicht verschließbar sind.The engine block is preferably designed in such a way that the apron covers the bores of the transverse screws and openings are provided in the apron for operating the transverse screws, which openings can be sealed oil-tight against oil leakage with sealing caps or locking screws or the like.

Für das Schwingungsverhalten ist es vorteilhaft, wenn zwischen der Schürze des Motorblocks und der Ölwanne zur zusätzlichen Versteifung der Schürze ein Leiterrahmen angeordnet ist.For the vibration behavior, it is advantageous if a lead frame is arranged between the skirt of the engine block and the oil pan for additional stiffening of the skirt.

Bei einer bevorzugten Ausführungsvariante ist vorgesehen, daß die Schürze oberhalb der Bohrungen der Querschrauben endet und durch einen abnehmbaren Teil über die Bohrungen der Querschrauben verlängert ist.In a preferred embodiment variant it is provided that the apron ends above the holes in the cross screws and is extended by a removable part over the holes in the cross screws.

Dabei ist es günstig, wenn der abnehmbare Teil die Ölwanne ist, deren Wände schürzenartig in Richtung der Motorhochachse verlängert sind.It is advantageous if the removable part is the oil pan, the walls of which are extended like an apron in the direction of the engine vertical axis.

Eine andere sehr vorteilhafte Ausführungsvariante der Erfindung mit verkürzter Schürze besteht darin, daß der abnehmbare Teil ein in Richtung der Motorhochachse schürzenartig gestalteter Leiterrahmen ist, der zwischen der Schürze des Motorblocks und der Ölwanne vorgesehen ist.Another very advantageous embodiment variant of the invention with a shortened apron is that the removable part is a ladder frame designed like an apron in the direction of the engine vertical axis, which is provided between the apron of the engine block and the oil pan.

Bei der erfindungsgemäßen Ausführung nach den Fig. 1 und 2 umfaßt die Brennkraftmaschine einen Motorblock 1, im Motorblock 1 hin- und hergehende Kolben 2, eine in den Hauptlagern 3 rotierende Kurbelwelle 4, zwischen Kolben 2 und Kurbelwelle 4 die Zylinderdruckkräfte übertragende Pleuelstangen 5, die Hauptlager 3 abstützende Hauptlagerbügel 6, die Hauptlagerhochschrauben 7 zur Aufnahme der Lagerkräfte in Hochverschraubungsrichtung Z, die Querschrauben 8 zur Aufnahme der geneigt einwirkenden Lagerkräfte sowie die an die Schürze 9 montierte Ölwanne 10. Weiters sind zwischen den Querschrauben 8 und der Innenseite 9' der Schürze 9 die Freistellungen 12 eingezeichnet.1 and 2, the internal combustion engine comprises an engine block 1, in the engine block 1 reciprocating piston 2, a rotating in the main bearings 3 crankshaft 4, between the piston 2 and crankshaft 4 the connecting rod 5 transmitting the cylinder pressure forces, the Main bearing 3 supporting main bearing bracket 6, the main bearing high screws 7 for absorbing the bearing forces in the direction of high screwing Z, the transverse screws 8 for absorbing the inclined bearing forces and the oil pan 10 mounted on the apron 9. Furthermore, between the transverse screws 8 and the inside 9 'of the apron 9 the exemptions 12 are drawn.

Durch diese Freistellungen 12 wird eine mittel- und hochfrequent wirksame Schwingungsisolation gegenüber der Schürze 9 und damit in weiterer Folge gegenüber der schallabstrahlenden Ölwanne 10 erreicht. Trotzdem ist eine seitliche Abstützung der Zylinderdruckkräfte und damit der seitlichen Hauptlagerkräfte gewährleistet. Zur Vermeidung dynamisch ungünstiger Kerbwirkungen im Freistellungsradius ist dieser festigkeitsmäßig sorgfältig auszubilden. Die Montage der Querschrauben 8 ist erfindungsgemäß über jeweils eine in der Schürzenwand 9 eingegossene Öffnung 15 möglich, welche gegen Ölaustritt mit Verschlußschrauben 12 od. dgl. öldicht verschlossen wird.By means of these exemptions 12, medium and high-frequency vibration isolation is achieved with respect to the apron 9 and thus subsequently with respect to the sound-radiating oil pan 10. Nevertheless, lateral support of the cylinder pressure forces and thus the lateral main bearing forces is guaranteed. To avoid dynamically unfavorable notch effects in the clearance radius, this must be carefully designed in terms of strength. The assembly of the transverse screws 8 is possible according to the invention via an opening 15 cast into the skirt wall 9, which is sealed oil-tight against oil leakage with screw plugs 12 or the like.

Die Schwingungsisolation ist besonders wirksam in Kombination mit einem in Fig. 3 und 4 dargestellten, zwischen Schürze 9 und Ölwanne 10 geschraubten Leiterrahmen 14 mit leitersprossenartigen Querstegen 14a unter den Hauptlagerbügeln 6 zwischen den in Motorlängsrichtung verlaufenden Leiterholmen 14b.The vibration isolation is particularly effective in combination with a lead frame 14 shown in FIGS. 3 and 4, screwed between the apron 9 and the oil pan 10, with cross bars 14a like rungs and rungs under the main bearing brackets 6 between the lead bars 14b running in the longitudinal direction of the engine.

Fig. 5 und 6 zeigen eine Ausführungsform mit verkürzter, oberhalb der Bohrungen der Querschrauben 8 endenden Schürze 9; nach Demontage der mit nach oben verlängerten Wänden 10a ausgestatteten Ölwanne 10 ist eine Bedienung der Querschrauben möglich.5 and 6 show an embodiment with a shortened apron 9 ending above the bores of the transverse screws 8; After dismantling the oil pan 10 equipped with walls 10a extended upwards, the cross screws can be operated.

Auch bei der Ausführungsform der verkürzten Schürze 9 ist die Kombination mit einem Leiterrahmen 14 sehr vorteilhaft, wie in Fig. 7 und 8 dargestellt ist. Der Leiterrahmen 14 weist nach oben verlängerte Leiterrahmenwände 14c auf. Nach Demontage desselben ist eine Bedienung der Querschrauben möglich.Also in the embodiment of the shortened apron 9, the combination with a lead frame 14 is very advantageous, as shown in FIGS. 7 and 8. The lead frame 14 has lead frame walls 14c elongated upwards. After disassembling it, the cross screws can be operated.

Die Erfindung ist ein wirksames Mittel, um die Schallemissionen von Hubkolbenmaschinen der eingangs erwähnten Art, vorzugsweise Brennkraftmaschinen, aber auch vorteilhaft bei Kompressoren, zu vermindern.The invention is an effective means of reducing the noise emissions from reciprocating piston machines of the type mentioned at the outset, preferably internal combustion engines, but also advantageously in the case of compressors.
