Abstract
Description
Die Erfindung betrifft ein Differential, insbesondere ein Zwischenachs differential für Kraftfahrzeuge, gemäß dem Oberbegriff des Patentan spruches 1.The invention relates to a differential, in particular an intermediate axle differential for motor vehicles, according to the preamble of the patent saying 1.
Insbesondere Zwischenachsdifferentiale bedingen oft relativ ineinander verschachtelte Anordnungen der An- und Abtriebselemente, um sowohl den baulichen als auch den räumlichen Zwängen Rechnung zu tragen. So zeigt beispielsweise der japanische Patentabstract 62-80 325 (A) ein Zwi schenachsdifferential, bei dem das die Planetenräder tragende Aus gleichsgehäuse einseitig offen ausgebildet ist und das dieser Seite benachbarte Zentralrad in einem separaten Abtriebsgehäuse gelagert ist. Der Kraftfluß verläuft in herkömmlicher Weise von dem angetriebenen Ausgleichsgehäuse mit den Planetenrädern auf die Zentralräder als Ab triebselemente.Interaxle differentials in particular often have a relatively large interdependence nested arrangements of the input and output elements to both the structural as well as the spatial constraints. So shows for example, Japanese Patent Abstract 62-80 325 (A) a Zwi rear axle differential, in which the planet gears carrying Aus equal housing is open on one side and this side adjacent central wheel is stored in a separate output housing. The power flow runs in a conventional manner from the driven Differential housing with the planet gears on the central gears as from drive elements.
Aufgabe der Erfindung ist es, ein baulich einfaches und herstellungs technisch günstiges Differential zu schaffen. Diese Aufgabe wird erfin dungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruches 1 ge löst. Besonders vorteilhafte Weiterbildungen der Erfindung sind den weiteren Patentansprüchen entnehmbar.The object of the invention is a structurally simple and manufacturing to create technically favorable differential. This task is invented accordingly with the characterizing features of claim 1 ge solves. Particularly advantageous developments of the invention are further claims can be found.
Erfindungsgemäß werden die Planetenräder über einen Zapfenstern ange trieben, der durch ein Zentralrad hindurch mit einer Antriebswelle trieblich verbunden ist. Werden die Planetenräder und die Zentralräder in axialer Richtung auf ihren Wellen bzw. Zapfen abgestützt, so kann das Ausgleichsgehäuse entfallen. According to the planet gears are attached via a spigot driven by a central gear with a drive shaft is driven. Become the planet gears and the central gears supported in the axial direction on their shafts or journals, so can the differential housing is eliminated.
Bevorzugt wird jedoch in Weiterbildung der Erfindung ein ein- oder mehrteiliges Gehäuse in Leichtbauweise vorgeschlagen, welches die Ab stützung zumindest der Zentralräder und gegebenenfalls der Planeten räder übernimmt. Eine Leichtbauweise ist deshalb möglich, weil der An triebs-Kraftfluß nicht über das Gehäuse, sondern über den innenliegen den Zapfenstern verläuft. Das Gehäuse kann deshalb beispielsweise aus faserverstärktem Kunststoff aus einer Aluminiumlegierung gegossen oder aber in Umformtechnik aus Blech hergestellt sein.However, in a further development of the invention, a single or multi-part housing proposed in lightweight construction, which the Ab support of at least the central wheels and possibly the planets wheels takes over. A lightweight construction is possible because the An drive power flow not over the housing, but over the inside the cone window runs. The housing can therefore be made, for example fiber-reinforced plastic cast from an aluminum alloy or but be made from sheet metal using forming technology.
Das Gehäuse kann einteilig sein, wobei durch entsprechende Ausnehmungen sichergestellt sein muß, daß die innenliegenden Teile wie Zentralräder, Planetenräder und insbesondere der Zapfenstern montierbar sind. In fer tigungstechnisch besonders günstiger Weise kann jedoch auch eine zwei- oder dreiteilige Bauweise verwendet werden, wobei gegebenenfalls bei einer zylindrischen Gestaltung des Ausgleichsgehäuses dessen Mantel durch ein einfaches Rohr gebildet sein kann.The housing can be in one piece, with corresponding recesses it must be ensured that the internal parts such as central wheels, Planetary gears and in particular the journal windows are mountable. In fer However, a two- or three-part construction can be used, where appropriate at a cylindrical design of the differential housing whose jacket can be formed by a simple tube.
Weitere zweckmäßige und vorteilhafte Merkmale der Erfindung sind der folgenden Beschreibung mehrerer Ausführungsbeispiele entnehmbar. Die schematische Zeichnung zeigt inFurther expedient and advantageous features of the invention are the following description of several embodiments. The schematic drawing shows in
Fig. 1 einen Längsschnitt durch ein Zwischenachsdifferential für das Antriebsaggregat eines vierradgetriebenen Kraftfahrzeuges mit innenliegendem, angetriebenem Zapfenstern und aus Leichtmetall bestehendem Gehäuse; Figure 1 shows a longitudinal section through an interaxle differential for the drive unit of a four-wheel drive motor vehicle with an internal, driven journal and housing made of light metal.

Fig. 4 ein Zwischenachsdifferential mit einem einteiligen Gehäuse aus Leichtmetall; und 4 shows an interaxle differential with a one-piece housing made of light metal; and
Fig. 5 einen Schnitt gemäß Linie V-V der Fig. 4 durch das Zwischen achsdifferential. Fig. 5 shows a section along line VV of Fig. 4 through the intermediate axle differential.
In der Fig. 1 ist mit 10 eine Antriebswelle für das Zwischenachsdiffe rential 12 bezeichnet, die an ihrem Ende über eine Steckverzahnung 14 mit einem Zapfenstern 16 trieblich verbunden ist. Der Zapfenstern 16 setzt sich zusammen aus einer Nabe 18 und zwei radial abragende Zapfen 20, auf denen die Planetenräder 22 drehbar gelagert sind.In Fig. 1, 10 denotes a drive shaft for the Zwischenachsdiff rential 12 , which is operatively connected at its end via a spline 14 with a pin 16 16 . The journal star 16 is composed of a hub 18 and two radially projecting journals 20 , on which the planet gears 22 are rotatably mounted.
Mit den Planetenrädern 22 in Eingriff sind zwei Zentralräder 24, 26, die ebenfalls über Verzahnungen 28, 30 einerseits mit der Abtriebswelle 32 und andererseits mit der Abtriebs-Hohlwelle 34 trieblich verbunden sind. Die Planetenräder 22 und die Zentralräder 24, 26 sind in bekannter Weise Kegelzahnräder.In engagement with the planet gears 22 are two central gears 24 , 26 , which are also connected via gears 28 , 30 on the one hand to the output shaft 32 and on the other hand to the hollow output shaft 34 . The planet gears 22 and the central gears 24 , 26 are bevel gears in a known manner.
Die Zentralräder 24, 26 weisen unterschiedliche wirksame Durchmesser (im Verzahnungsbereich) auf, so daß durch das Zwischenachsdifferential 12 auf die Abtriebswellen 32, 34 eine ungleiche Drehmomentaufteilung er folgt. Dem Rechnung tragend sind die Zapfen 20 des Zapfensternes 16 in einem definierten Winkel zu einer senkrechten durch die Drehachse des Differentiales 12 geneigt.The central wheels 24 , 26 have different effective diameters (in the toothing area), so that he follows an uneven torque distribution through the interaxle differential 12 on the output shafts 32 , 34 . Taking this into account, the pins 20 of the pin star 16 are inclined at a defined angle to a perpendicular through the axis of rotation of the differential 12 .
Zur jeweils in axialer Richtung wirkenden Abstützung der Kegelräder 22, 24, 26 ist ein im Gießverfahren hergestelltes Gehäuse 36 vorgesehen, welches sich aus einem rotationssymmetrischen, kelchförmigen Gehäuse abschnitt 38 und einem flanschförmigen Gehäuseabschnitt 40 mit zur Drehachse senkrechter Teilungsebene zusammensetzt. Der Gehäuseabschnitt 40 ist in dem Gehäuseabschnitt 38 mittels eines eingesprengten Siche rungsringes 42 gehalten. Zwischen den sphärischen Anlaufflächen 44 am Zentralrad 26 und den sphärischen Anlaufflächen 46 an den Planeten rädern 22 sowie zwischen der stirnseitigen Anlauffläche 48 des Zentral rades 24 und dem Gehäuse 36 an den entsprechenden Innenflächen ist zum Spielausgleich eine Kunststoffscheibe 50 bzw. eine Kunststoffschale 52 vorgesehen. Ferner ist das Gehäuse 36 auf der Hohlwelle 34 bzw. auf der Abtriebswelle 32 durch aus Kunststoff hergestellte Lagerschalen 54, 56 verdrehbar gelagert.For each acting in the axial direction supporting the bevel gears 22 , 24 , 26 , a housing 36 is provided in the casting process, which is composed of a rotationally symmetrical, cup-shaped housing section 38 and a flange-shaped housing section 40 with the plane of rotation perpendicular to the axis of rotation. The housing section 40 is held in the housing section 38 by means of a detonated hedging ring 42 . Between the spherical contact surfaces 44 on the central wheel 26 and the spherical contact surfaces 46 on the planet wheels 22 and between the end face 48 of the central wheel 24 and the housing 36 on the corresponding inner surfaces, a plastic disk 50 or a plastic shell 52 is provided to compensate for play. Furthermore, the housing 36 is rotatably supported on the hollow shaft 34 or on the output shaft 32 by bearing shells 54 , 56 made of plastic.
Die Hohlwelle 34 ist in nicht dargestellter Weise an eine Abtriebswelle eines nicht dargestellten Geschwindigkeits-Wechselgetriebes angeschlos sen und treibt über den Zapfenstern 16 die Planetenräder 22 an. Diese sind mit den Zentralrädern 24, 26 in Eingriff und übertragen das Drehmo ment in dem vorbestimmten Verhältnis auf die Hohlwelle 34 und die Ab triebswelle 32. Dabei kann die Hohlwelle 34 trieblich mit einer Hinter achse des Kraftfahrzeuges und die Antriebswelle 32 mit der Vorderachse verbunden sein.The hollow shaft 34 is in a manner not shown to an output shaft of a speed change gear, not shown, ruled out and drives the pinion gears 16 on the planet gears 22 . These are in engagement with the central wheels 24 , 26 and transmit the torque in the predetermined ratio to the hollow shaft 34 and from the drive shaft 32nd The hollow shaft 34 can be connected to a rear axle of the motor vehicle and the drive shaft 32 can be connected to the front axle.
Die axiale Fixierung des gesamten Zwischenachsdifferentiales kann ent weder über den Zapfenstern 16 erfolgen, der beispielsweise mittels eines nicht dargestellten Sicherungsringes fest mit der Antriebswelle 10 verbunden sein kann. Gleiches gilt jedoch auch für das Zentralrad 26 und/oder das Zentralrad 24. Es reicht jedenfalls aus, eines der drei genannten Funktionselemente axial zu sichern. Das Gehäuse 36 dient le diglich dazu, die Zentralräder und die Planetenräder in der jeweils axialen Richtung abzustützen und deren korrekten Eingriff sicherzu stellen. Über das Gehäuse 36 wird jedoch kein Drehmoment bzw. Antriebs moment übertragen.The axial fixation of the entire interaxle differential can be carried out either via the journal 16 , which can be fixedly connected to the drive shaft 10 , for example, by means of a retaining ring (not shown). However, the same also applies to the central gear 26 and / or the central gear 24 . In any case, it is sufficient to axially secure one of the three functional elements mentioned. The housing 36 serves le diglich to support the central gears and the planet gears in the respective axial direction and to ensure their correct engagement. However, no torque or drive torque is transmitted via the housing 36 .
Sofern aber sowohl die Zentralräder 24, 26 als auch die Planetenräder 22 axial auf ihren entsprechenden Antriebs bzw. Abtriebselementen gesi chert sind, könnte das Gehäuse 36 auch entfallen. Im Verbindungsbereich (Verzahnung 28) zwischen der Abtriebs-Hohlwelle 34 und dem Zentralrad 24 ist zwischen der Hohlwelle 34 und der Antriebswelle 10 ein Nadel lager 58 vorgesehen, welches eine reibungsarme Relativverdrehung zwi schen der Hohlwelle 34 und der Antriebswelle 10 z. B. beim Durch rutschen der Räder einer Achse des Kraftfahrzeuges sicherstellt.However, if both the central gears 24 , 26 and the planet gears 22 are secured axially on their corresponding drive or output elements, the housing 36 could also be omitted. In the connection area (toothing 28 ) between the output hollow shaft 34 and the central gear 24 , a needle bearing 58 is provided between the hollow shaft 34 and the drive shaft 10 , which low-friction relative rotation between the hollow shaft 34 and the drive shaft 10 z. B. ensures by slipping the wheels of an axis of the motor vehicle.
Das in der Fig. 2 gezeigte Zwischenachsdifferential 60 ist nur soweit beschrieben, als es sich wesentlich von dem Zwischenachsdifferential gemäß Fig. 1 unterscheidet. Dabei besteht dessen Gehäuse 62 aus einem Stahlblech, welches im Tiefziehverfahren umgeformt wurde. Das Gehäuse ist über Nadellager 64, 66 auf der Hohlwelle 34 bzw. der Abtriebswelle 32 gelagert. Der wiederum etwa tulpenförmige Gehäuseabschnitt 68 ist über einen Sicherungsring 70 mit einem ebenfalls eine sphärische Stütz fläche 72 aufweisenden Deckel 74 verbunden. Dabei erfolgt auch die Ab stützung des im Durchmesser größeren Zentralrades 24′ über eine sphäri sche Anlauffläche 76. Das Gehäuse 60 ist über Spannstifte 78 in Dreh richtung mit dem Zapfenstern 16′ verbunden. Dabei weist der Zapfenstern 16′ in den Zapfen 20′ zentrische Bohrungen 80 auf, in die die Spann stifte 78 eingeschlagen sind, wobei diese in den Gehäuseabschnitt 68 eingearbeitete Langlöcher 82 durchdringen. Die Spannstifte 78 bilden damit eine Verdrehsicherung zwischen dem Zapfenstern 16′ und dem Ge häuse 62, wodurch bei gleichen Drehgeschwindigkeiten der Abtriebswellen 32, 34 gegebenenfalls auftretende Relativverdrehungen zwischen dem Zapfenstern 16′ und dem Gehäuse 62 unterbunden sind.The interaxle differential 60 shown in FIG. 2 is only described to the extent that it differs significantly from the interaxle differential according to FIG. 1. The housing 62 consists of a steel sheet which has been formed using the deep-drawing process. The housing is mounted on the hollow shaft 34 and the output shaft 32 via needle bearings 64, 66 . The again approximately tulip-shaped housing section 68 is connected via a locking ring 70 with a likewise spherical support surface 72 having cover 74 . In this case, the support from the larger central wheel 24 'takes place via a spherical contact surface 76 . The housing 60 is connected via dowel pins 78 in the direction of rotation with the pivot window 16 '. The spigot 16 'in the pin 20 ' has central bores 80 , into which the clamping pins 78 are hammered, which penetrate into the housing section 68 elongated holes 82 . The dowel pins 78 thus form an anti-rotation device between the journal 16 'and the Ge housing 62 , which, at the same rotational speeds of the output shafts 32, 34, possibly occurring relative rotations between the journal 16 ' and the housing 62 are prevented.
In der Ausführung gemäß Fig. 3 weist das Zwischenachsdifferential 90 ein zylindrisches Gehäuse 92 auf, welches aus einem rohrförmigen Ab schnitt 94 und zwei Deckeln 96, 98 gebildet ist. Die Deckel 96, 98 sind wiederum mit Sicherungsringen 100, 102 mit dem Abschnitt 94 verbunden. Die Verbindung könnte jedoch gegebenenfalls auch durch Umbördeln oder Einrollen der Endbereiche des Rohres 94 hergestellt sein.In the embodiment according to FIG. 3, the interaxle differential 90 has a cylindrical housing 92 , which is made from a tubular section 94 and two covers 96 , 98 are formed. The covers 96 , 98 are in turn connected to the section 94 by means of retaining rings 100 , 102 . However, the connection could possibly also be made by flanging or rolling the end regions of the tube 94 .
Die Zentralräder 24′′ bzw. 26′′ sind mit radial planen Anlaufflächen 104, 105 an den Deckeln 96, 98 axial abgestützt, wobei gegebenenfalls in ihrer Stärke unterschiedliche Anlaufscheiben auch zur Einstellung des Zahnspieles zwischen den Zentralrädern 24, 26 und den Planetenrädern 22′′ vorgesehen sein können.The central wheels 24 '' and 26 '' are supported axially with radially planar thrust surfaces 104 , 105 on the covers 96 , 98 , with thrust washers of different thicknesses also for adjusting the tooth play between the central gears 24 , 26 and the planet gears 22 ''Can be provided.
Die Planetenräder 22′′ sind auf den Zapfen 20′′ des Zapfensternes 16′′ drehbar gelagert. Zur axialen Abstützung der Planetenräder 22′′ sind in die Zapfen 20′′ Gewindebohrungen 106 eingebracht, in die Schrauben 108 mit Köpfen mit großen Anlaufflächen 110 eingeschraubt sind. Die Plane tenräder 22′′ sind somit nicht an dem Gehäuse 92 abgestützt. The planet gears 22 '' are rotatably mounted on the pin 20 '' of the pin star 16 ''. For axial support of the planet gears 22 '' in the pin 20 '' threaded holes 106 are introduced into which screws 108 are screwed with heads with large contact surfaces 110 . The tarpaulin wheels 22 '' are thus not supported on the housing 92 .
Die Fig. 4 und 5 schließlich zeigen ein Zwischenachsdifferential 112 im wesentlichen gleicher Bauart, jedoch mit einem einteiligen Gehäuse 114, das sich aus zwei rotationssymmetrischen Flanschen 116, 118 und zwei diametral gegenüberliegenden Stegen 120, 122 zusammensetzt. Die Stege 120, 122 sind an die Flansche angeformt bzw. einteilig mit diesen aus einer Al-Legierung gegossen. FIGS. 4 and 5 finally show an interaxle 112 substantially identical construction, but that is composed of two rotationally symmetrical flanges 116, 118 and two diametrically opposed flanges 120,122 with a one-piece housing 114. The webs 120 , 122 are molded onto the flanges or cast in one piece with them from an Al alloy.
Die planen Anlaufflächen 124, 126, 128 für die Zentralräder 24′′′, 26′′′ und die Planetenräder 22′′′ innerhalb des Gehäuses 114 sind durch Räumen hergestellt, wobei aufgrund der großen, zwischen den Stegen in Umfangsrichtung gebildeten Freiräume bzw. eine gute Zugänglichkeit für das Räumwerkzeug gegeben ist.The flat contact surfaces 124 , 126 , 128 for the central gears 24 ''', 26 ''' and the planet gears 22 '''within the housing 114 are made by spaces, whereby due to the large, formed between the webs in the circumferential direction or the broaching tool is easily accessible.
