Description

Die Erfindung bezieht sich auf ein gemäß dem Oberbegriff des Patentanspruches 1 gestaltetes Antriebsaggregat für Kraftfahrzeuge.The invention relates to a drive unit for motor vehicles designed according to the preamble of patent claim 1.

Zur Reduzierung der durch Oberflächenschwingungen von Abschnitten eines Antriebsaggregates verursachten Schallabstrahlung ist es bekannt, derartige, vor allem gering belastete Abschnitte aus einem weichelastischem Material mit hoher Dämpfung auszubilden.In order to reduce the sound radiation caused by surface vibrations of sections of a drive unit, it is known to form such, especially lightly loaded sections from a soft, elastic material with high damping.

So ist beispielsweise aus der EP 0 437 086 B für eine Hubkolbenmaschine ein Maschinengehäuse bekannt, bei dem der die Zylinder umgebende Kühlmittelraum von Wänden aus einem Elastomer bzw. einem Kunststoff begrenzt ist.For example, a machine housing is known from EP 0 437 086 B for a reciprocating piston machine, in which the coolant space surrounding the cylinders is delimited by walls made of an elastomer or a plastic.

Weiter ist aus der DE 38 38 250 C eine aus Kunststoff gefertigte Ölwanne für eine Brennkraftmaschine bekannt.Furthermore, an oil pan made of plastic for an internal combustion engine is known from DE 38 38 250 C.

Schließlich zeigt und beschreibt die DE-U 83 23 945 eine Ölwanne für Brennkraftmaschinen, die zur Reduzierung des Motorgeräusches aus Vollgummi geformt und mit aussteifenden Rippen auf der Außenseite gestaltet ist. Die am Maschinengehäuse der Brennkraftmaschine frei hängend angeordnete Vollgummi-Ölwanne ist über einen angeformten Dichtflansch gehalten, der zwischen einem Halteflansch des Maschinengehäuses und einem gesonderten Spannflansch vorgespannt angeordnet ist.Finally, DE-U 83 23 945 shows and describes an oil pan for internal combustion engines, which is formed from solid rubber to reduce engine noise and is designed with stiffening ribs on the outside. The solid rubber oil pan, which is freely suspended on the machine housing of the internal combustion engine, is held by means of a molded-on sealing flange, which is between a holding flange of the machine housing and a separate clamping flange is arranged biased.

Ferner ist es weiter bekannt, daß der Lärmpegel eines aus einer Hubkolben-Brennkraftmaschine und einem Getriebe gebildeten Aggregates wesentlich auch durch die Steifigkeit der mittels Verschraubung erzielten Verbindung von Maschinengehäuse und Getriebegehäuse bestimmt ist.Furthermore, it is also known that the noise level of an assembly formed from a reciprocating piston internal combustion engine and a transmission is also essentially determined by the rigidity of the connection between the machine housing and the transmission housing achieved by means of screwing.

Der Erfindung liegt die Aufgabe zugrunde, für ein gattungsgemäßes Antriebsaggregat mit weichelastischer Ölwanne eine Anordnung aufzuzeigen, die bei wirksamer Versteifung der Verbindung von Hubkolben-Maschinengehäuse und Getriebegehäuse zugleich einen Schutz der Ölwanne gewährleistet.The invention has for its object to provide an arrangement for a generic drive unit with a flexible oil sump, which ensures effective protection of the oil pan at the same time as an effective stiffening of the connection between the reciprocating piston machine housing and the transmission housing.

Diese Aufgabe ist mit dem Patentanspruch dadurch gelöst, daß der Spannflansch mit einem die weichelastische Ölwanne außenseitig stützenden Gitterrahmen aus biegefestem Material verbunden ist, wobei der Gitterrahmen mittels eines getriebeseitig vorgesehenen Verbindungsflansches eine dreh- und biegesteife Abstützung zwischen Maschinengehäuse und angeflanschtem Getriebegehäuse bewirkt.This object is achieved with the patent claim in that the clamping flange is connected to a lattice frame made of flex-resistant material on the outside supporting the flexible oil pan, the lattice frame using a connecting flange provided on the gearbox side to provide a torsionally and flexurally rigid support between the machine housing and the flanged gearbox housing.

Die Erfindung ergibt neben dem Vorteil einer durch eine im wesentlichen glattflächige Außengestaltung vereinfachten weichelastischen Ölwanne mit dem diese stützenden und schützenden Gitterrahmen den weiteren Vorteil eines leichtgewichtigen Versteifungselementes zwischen dem Maschinengehäuse und dem angeflanschten Getriebegehäuse.In addition to the advantage of a flexible, elastic oil pan, which is simplified by an essentially smooth outer surface design, with the supporting and protective lattice frame, the invention also has the advantage of a lightweight stiffening element between the machine housing and the flanged gear housing.

Hinsichtlich einer leichtgewichtigen und steifen Ausbildung des Gitterrahmens ist dieser in Ausgestaltung der Erfindung vorzugsweise als ein Leichtmetall-Gußteil vorgesehen mit im Querschnitt T-förmigen Gitterstäben.With regard to a light-weight and stiff design of the lattice frame, in the embodiment of the invention it is preferably provided as a light metal casting with lattice bars which are T-shaped in cross section.

Ein Antriebsaggregat 1 für Kraftfahrzeuge, insbesondere PKW, umfaßt eine Hubkolbenmaschine 2 und ein angeflanschtes Getriebegehäuse 3, wobei der Hubkolbenmaschine 2 zur Reduzierung der Abstrahlung des Motorgeräusches eine weichelastische Ölwanne 4 - Figur 2 - aus einem Elastomer bzw. einem Kunststoff zugeordnet ist. Wie aus Figur 3 ersichtlich, weist die Ölwanne 4 einen angeformten Dichtflansch 5 auf, der zwischen einem Halteflansch 6 des Hubkolben-Maschinengehäuses 2' und einem Spannflansch 7 mittels Spannschrauben 8 vorgespannt angeordnet ist. Zur Begrenzung der elastischen Vorspannung des Dichtflansches 5 weist dieser in jeder Durchbrechung 9 angeordnete Abstandshülsen 10 auf.A drive unit 1 for motor vehicles, in particular cars, comprises a reciprocating piston machine 2 and a flanged gear housing 3, with the reciprocating piston machine 2 being assigned a soft-elastic oil pan 4 - FIG. 2 - made of an elastomer or a plastic in order to reduce the radiation from the engine noise. As can be seen from FIG. 3, the oil pan 4 has a molded-on sealing flange 5 which is arranged between a holding flange 6 of the reciprocating piston machine housing 2 'and a clamping flange 7 by means of clamping screws 8. To limit the elastic prestressing of the sealing flange 5, this has spacer sleeves 10 arranged in each opening 9.

Der Spannflansch 7 ist erfindungsgemäß Teil eines die weichelastische Ölwanne 4 außenseitig stützenden Gitterrahmens 11 aus biegefestem Material. Vorzugsweise ist der die Ölwanne 4 stützende und schützende Gitterrahmen 11 aus Gewichtsgründen als ein Leichtmetall-Gußteil gestaltet, wobei zur Erzielung einer hohen Festigkeit bei geringem Gewicht die Gitterstäbe 12 des Gitterrahmens 11 im Querschnitt T-förmig gestaltet sind. Weiter ist die Anordnung der Gitterstäbe 12 so getroffen, daß die durch den Gitterrahmen 11 erfindungsgemäß unterstützte Ölwanne 4 von relativer dünner Wandstärke mit ihrer glatt ausgebildeten Außenseite auf den Kopfstreben 13 der T-förmigen Gitterstäbe 12 aufliegt.The clamping flange 7 is, according to the invention, part of a lattice frame 11 made of a flex-resistant material that supports the flexible oil pan 4 on the outside. For reasons of weight, the lattice frame 11 supporting and protecting the oil pan 4 is preferably designed as a light metal casting, the lattice bars 12 of the lattice frame 11 being T-shaped in cross section in order to achieve high strength and low weight. Furthermore, the arrangement of the bars 12 is such that the oil pan 4 supported by the lattice frame 11 of relatively thin wall thickness with its smooth outer surface rests on the head struts 13 of the T-shaped bars 12.

Neben der erfindungsgemäß stützenden und schützenden Funktion kommt dem Gitterrahmen in weiterer erfindungsgemäßer Kombination eine die Verbindung des Maschinengehäuses 2' mit dem angeflanschten Getriebegehäuse 3 versteifende Funktion zu. Hierfür ist der Gitterrahmen 11 mit einem getriebeseitig angeordneten Verbindungsflansch 14 versehen, mittels dem eine dreh- und biegesteife Abstützung zwischen dem Maschinengehäuse 2' und dem angeflanschten Getriebegehäuse 3 bewirkt ist.In addition to the supporting and protective function according to the invention, the lattice frame in a further combination according to the invention has a function stiffening the connection of the machine housing 2 'to the flanged-on transmission housing 3. For this purpose, the lattice frame 11 is provided with a connecting flange 14 arranged on the transmission side, by means of which a torsionally and flexurally rigid support between the machine housing 2 'and the flanged transmission housing 3 is effected.

Die über den erfindungsgemäßen Gitterrahmen 11 zusätzlich ausgesteifte Verbindung von Maschinengehäuse 2' und Getriebegehäuse 3 bewirkt neben der weichelastischen Ölwanne 4 eine weitere Absenkung des vom Antriebsaggregat 1 abgestrahlten Geräusches.The additionally stiffened connection of the machine housing 2 'and gear housing 3 via the lattice frame 11 according to the invention brings about a further reduction in the noise emitted by the drive unit 1 in addition to the flexible oil pan 4.
