Description

Elastische Lagerung eines Antriebsaggregates mit unmittelbar daran anschließenden angetriebenen Schwinghalbachsen im freitragenden Aufbau eines Kraftwagens Die Erfindung bezieht sich auf eine elastische Lagerung eines Antriebsaggregates mit unmittelbar daran anschließenden Schwinghalbachsen im freitragenden Aufbau eines Kraftwagens.Elastic mounting of a drive unit with directly on it subsequent driven oscillating half-axles in the self-supporting structure of a motor vehicle The invention relates to an elastic mounting of a drive unit with directly adjoining oscillating half-axes in the self-supporting structure of a Motor vehicle.

Die elastische Lagerung der Antriebsaggregate, d. h. des Motors einschließlich Getriebegehäuse, bezweckt die Verhinderung der Übertragung der Schwingungen vom Motor in den Aufbau des Fahrzeuges. Derartige Lagerungen sind in der Form bekanntgeworden, daß das aus Motor und Getriebegehäuse gebildete Antriebsaggregat in zwei elastischen Ringen gelagert ist, von denen der eine das Kupplungsgehäuse des Antriebsaggregates umschließt. Ist jedoch das Antriebsaggregat mit den Triebrädern so verbunden, daß in dasselbe auch die auf die Triebräder einwirkenden Kräftekomponenten abgeleitet werden, wie dies bei einem Antriebsaggregat mit angetriebenen Schwinghalbachsen der Fall ist, dann muß die elastische Lagerung des Aggregates eine freie Motorbewegung ungefähr um eine durch den Schwerpunkt des Aggregates verlaufende Achse zulassen und dabei außerdem sämtliche Reaktionen von den auf die Triebräder des Fahrzeuges einwirkenden Kräften auffangen. Die elastische Lagerung darf in diesem Fall keine größeren Verformungen, weder in der Querachse noch in der Längsrichtung des Antriebsaggregates, gestatten, da diese eine schlechte Führung .der Triebräder, schlechten Halt und übermäßigen Verschleiß der Gummireifen zur Folge haben würden. Anderseits muß die Lagerung so ausgebildet werden, daß sie zwecks guter Abdämpfung der Motorvibrationen wesentliche Verformungen um die Schwingungsachse ermöglicht.The elastic mounting of the drive units, d. H. of the engine including The purpose of the gearbox housing is to prevent the transmission of vibrations from the Engine in the body of the vehicle. Such bearings have become known in the form that the drive unit formed from the motor and gear housing in two elastic Rings is mounted, one of which is the clutch housing of the drive unit encloses. However, if the drive unit is connected to the drive wheels in such a way that the components of forces acting on the driving wheels are also derived from this are, as is the case with a drive unit with driven oscillating half-axles is the case, then the elastic mounting of the unit must allow free motor movement Allow about an axis running through the center of gravity of the unit and also all the reactions from the vehicle's driving wheels acting forces to catch. The elastic mounting may be in in this case no major deformations, neither in the transverse axis nor in the longitudinal direction of the drive unit, as this allows poor guidance of the drive wheels, result in poor grip and excessive tire wear. On the other hand, the storage must be designed so that it is for the purpose of good damping the engine vibration enables significant deformations around the vibration axis.

Die bisher bekannten Lagerungsbauarten, die diesen letztgenannten Bedingungen Rechnung tragen sollen, sind so ausgeführt, daß Kautschukelemente im gegabelten Rahmen oder im Mittelträger des Fußbodens abgestützt sind. Ein solcher Gabelträger ist entweder kostspielig und schwer, oder er weist stets eine unerwünschte Elastizität in der Querrichtung auf, welche die Räderführung ungünstig beeinflußt.The previously known types of storage, the latter Conditions should take into account, are designed so that rubber elements in the forked frame or are supported in the central beam of the floor. Such a Fork carriage is either expensive and heavy, or it always has an undesirable one Elasticity in the transverse direction, which adversely affects the wheel guidance.

Gegenstand der vorliegenden Erfindung ist eine elastische Lagerung eines Antriebsaggregates mit unmittelbar daran anschließenden Schwinghalbächsen im freitragenden Aüfbau eines Kraftwagens, die durch die Kombination folgender Merkmale gekennzeichnet ist: a) Das Antriebsaggregat ist in an sich bekannter Weise in zwei elastischen Ringen gelagert, von denen der eine vor und der andere hinter der Anschlußstelle der Schwinghalbachsen je innerhalb einer Querebene derart angeordnet ist, daß der Schwerpunkt des Antriebsaggregates etwa auf der durch die beiden Ringmitten verlaufenden Geraden liegt; b) der eine elastische Ring ist in der Nähe des Schwerpunktes zwischen diesem und der Anschlußstelle der Schwinghalbachsen, z. B. in an sich bekannter Weise am Kupplungsgehäuse des Antriebsaggregates, angeordnet und umschließt den dortigen Teil des Antriebsaggregates ganz; c) der in der Nähe des Schwerpunkte's des Antriebsaggregates gelagerte elastische Ring ist direkt in einer Querwand des freitragenden Wagenaufbaues fest abgestützt.The subject of the present invention is an elastic mounting a drive unit with directly adjoining oscillating half-axes in the self-supporting structure of a motor vehicle, which is achieved through the combination of the following features is characterized: a) The drive unit is in a known manner in two stored elastic rings, one of which is in front of and the other behind the connection point the oscillation half-axes is arranged within a transverse plane in such a way that the The main focus of the drive unit is roughly on that running through the two ring centers Straight line; b) the one elastic ring is located near the center of gravity between this and the connection point of the swinging half-axes, z. B. in itself known Way on the clutch housing of the drive unit, arranged and encloses the part of the drive unit there entirely; c) the one near the center of gravity of the drive unit mounted elastic ring is directly in a transverse wall of the cantilevered car body firmly supported.

Diese konstruktive Lösung bietet außer der Möglichkeit einer richtigen Lagerung nach den vorstehend angeführten Grundsätzen noch den wesentlichen Vorteil, daß die Gesamtlagerung besonders wenig Raum einnimmt.This constructive solution offers besides the possibility of a correct one Storage according to the above principles still has the essential advantage, that the overall storage takes up particularly little space.

Ein Ausführungsbeispiel der Lagerung des Antriebsaggregates indem freitragenden Aufbau eines Personenkraftwagens gemäß der Erfindung ist in der Zeichnung schematisch veranschaulicht; es zeigt Abb. I eine stirnseitige Ansicht der Lagerung in Richtung der Pfeile der zugehörigen Schnittlinie in Abb. 2 und Abb. 2 einen senkrechten Längsschnitt in der Achsebene des Antriebsaggregates.An embodiment of the storage of the drive unit by cantilevered structure of a passenger car according to the invention is in the drawing schematically illustrated; Fig. I shows a front view of the bearing in the direction of the arrows of the associated cutting line in Fig. 2 and Fig. 2 a vertical Longitudinal section in the axial plane of the drive unit.

Das Antriebsaggregat besteht aus dem Motor I und dem Hinterachsgehäuse 2, in welchem das Kupplungsgehäuse, der Getriebekasten sowie das Kegelrädergehäuse mit dem Differential vereinigt sind. Der Antrieb der Schwinghalbachsen 3 erfolgt in üblicher Weise über Gelenke; die Schub- und Bremskräfte werden gleichfalls in an sich bekannter Weise aufgefangen, z. B. durch Stützen. Das ganze Antriebsaggregat ist in Blech-Querversteifungen des Aufbaues mittels zweier elastischer Ringe gelagert, wobei es darauf ankommt, daß einer dieser Ringe näher zum Schwerpunkt des Aggregates angebracht ist, z. B. am Kupplungsgehäuse, und dieses am ganzen Umfang umschließt.The drive unit consists of the engine I and the rear axle housing 2, in which the clutch housing, the gear box and the bevel gear housing are united with the differential. The swinging half-axles 3 are driven in the usual way via joints; the thrust and braking forces are also in collected in a known manner, z. B. by supports. The whole drive unit is mounted in sheet metal cross stiffeners of the superstructure by means of two elastic rings, it is important that one of these rings is closer to the center of gravity of the unit attached, e.g. B. on the clutch housing, and this encloses the entire circumference.

Das Vorderende des Antriebsaggregates ist in einem elastischen Ring gelagert, der aus zwei Hälften besteht, deren Teilebene waagerecht durch die Achse verläuft. Die obere Hälfte 5 wird mittels eines Blechflansches unmittelbar in einer Blech-Ouerversteifung der Karosserie gehalten, während die untere Hälfte 6 mittels eines Joches 7 an der oberen Hälfte befestigt (angeschraubt) ist. Dieser Ring ist dazu bestimmt, hauptsächlich die Reaktionen der Schubkräfte S1 und der Bremskräfte S2 sowie auch einen Teil des Aggregatgewichtes aufzufangen. Die auf die Achse bei der Fahrt in Kehren wirkenden Querkräfte S3, die Reaktionen der auf die Räder 21 des Kraftwagens wirkenden lotrechten Kräfte S4 und des Aggregatgewichtes G werden von dem großen elastischen Ring aufgefangen, der den ganzen Umfang des Kupplungsgehäuses 22 umschließt, und zwar in der Nähe des Aggregatschwerpunktes T. Dieser Ring ist ebenso wie der schon erwähnte kleinere Ring aus zwei Hälften zusammengesetzt, von denen die obere, 8, unmittelbar im Aufbau gehalten wird und die untere, 9, mit Hilfe eines Joches Io an die obere Hälfte angeschraubt ist. Beide Ringe sind derart angeordnet, daß die Verbindungslinie a der Mittelpunkte b und c, um welche sich die Ringe verformen, durch den Schwerpunkt T des Antriebsaggregates verläuft. Damit werden die an eine richtige Lagerung des Aggregates zu stellenden Bedingungen erfüllt, so daß es frei um seine Trägheitsachse schwingen kann, wobei beide Ringe durch die Kräfte S5 und S6 nur auf Schub, d. h. in einer Richtung beansprucht werden, in welcher die Ringe sehr weich sind.The front end of the drive unit is in an elastic ring stored, which consists of two halves, the sub-plane horizontally through the axis runs. The upper half 5 is by means of a sheet metal flange directly in a Sheet metal Ouerversteifung held the body, while the lower half 6 means a yoke 7 is attached (screwed) to the upper half. This ring is intended mainly the reactions of the thrust forces S1 and the braking forces S2 as well as a part of the aggregate weight. The one on the axis the transverse forces S3 acting on the drive in bends, the reactions of the 21 of the motor vehicle acting perpendicular forces S4 and the unit weight G are caught by the large elastic ring that runs the entire circumference of the clutch housing 22 encloses, in the vicinity of the unit's center of gravity T. This ring is just like the smaller ring already mentioned, composed of two halves, of which the upper, 8, is held directly in the construction and the lower, 9, with help of a yoke Io is screwed to the upper half. Both rings are arranged in such a way that the connecting line a of the centers b and c, around which the rings deform, runs through the center of gravity T of the drive unit. This means that they will be sent to a correct storage of the unit to be met conditions, so that it is free can oscillate about its axis of inertia, both rings by the forces S5 and S6 only on thrust, i.e. H. are stressed in a direction in which the rings are very soft.

Der vordere Ring, der elastisch ist, wird von der Querversteifungswand IIi der freitragenden Karosserie getragen, während der hintere Ring von der Wand 12 der Karosserie gehalten wird. Diese Wand ist mittels der eingepreßten Versteifungselemente i3, 1q., 15 verstärkt, @die von den Befestigungsschrauben 16 des Joches io zu den von .den Blechen der Wände 12, 17, 18 und den Unterzügen 2o gebildeten festen Knoten derart verlaufen, daß alle auf Aden Ring einwirkenden Kräfte in.. diese festen Punkte abgeleitet werden.The front ring, which is elastic, is carried by the transverse reinforcement wall IIi of the cantilever body, while the rear ring is supported by the wall 12 of the body. This wall is reinforced by means of the pressed-in stiffening elements i3, 1q., 15 , @the of the fastening screws 16 of the yoke io to the fixed knots formed by the sheets of the walls 12, 17, 18 and the beams 2o run in such a way that all of them run on Aden ring forces acting in .. these fixed points are derived.
