Sowohl bei der Übertragung größerer Drehmomente als auch bei beengten Platzverhältnissen, beispielsweise bei in die Kegellager integrierten Gelenken, hat sich diese Anordnung mit aufwendigen Schaltgliedern als nicht mehr geeignet erwiesen.Both when transmitting larger torques as well in confined spaces, for example in the Tapered bearing integrated joints, this arrangement has become with elaborate switching elements proved to be no longer suitable.
Die Aufgabe der Erfindung besteht darin, den bekannten Stand der Technik sowohl für größere Drehmomente als auch größere Nabendurchmesser bei an sich kleinbleibenden Kegelraddurchmessern auf kostengünstige und wartungsfreundliche Weise umzugestalten.The object of the invention is the known State of the art for both larger torques as well Larger hub diameters with small bevel gear diameters to inexpensive and easy to maintain Way to remodel.
Die Lösung wird mit den im Kennzeichen des Anspruches 1 angegebenen Merkmalen insbesondere dadurch erreicht, daß durch Anordnung der Schaltglieder auf dem größten verfügbaren Durchmesser die Zahl der Schaltglieder, ohne deren Durchmesser zu verringern, erhöht werden kann. Dabei wird außerdem Platz für eine Kegelradnabe etwa gleichen Durchmessers geschaffen, deren Hohlraum nun Platz bietet, nötigenfalls nächstmöglich zum Kegelrad, z. B. im Bereich unterhalb der Schaltglieder, noch ein Wellengelenk einzubauen.The solution is with the in the characterizing part of claim 1 specified features achieved in particular by that Arrangement of the switching elements on the largest available diameter the number of switching elements without increasing their diameter decrease, can be increased. There is also space for created a bevel gear hub of approximately the same diameter, the Cavity now offers space, if necessary as close as possible to the bevel gear, e.g. B. in the area below the switching elements, still a Install shaft joint.
Weitere Ausgestaltungsmöglichkeiten der Erfindung sind in den Unteransprüchen angegeben. Further design options of the invention are in specified in the subclaims.
Nach Anspruch 2 kann durch eine von außen zugängige Axialsicherung in der Führungshülse die gesamte Kegelradnabe leicht ohne völlige Demontage des Differentialkorbes aus dem Getriebegehäuse bei Bedarf aus einem Gehäusedeckel herausgezogen werden.According to claim 2 can by an externally accessible axial lock the entire bevel gear hub in the guide sleeve without completely disassembling the differential carrier from the gearbox can be pulled out of a housing cover if necessary.

Weitere Vorteile und Einzelheiten der Erfindung sind aus den drei Ausführungsbeispiele darstellenden Schnittzeichnungen Fig. 1 bis Fig. 3 ersichtlich.Further advantages and details of the invention are representative of the three embodiments sectional drawings Fig. 1 to Fig. 3 can be seen.
In Fig. 1 verfügt das Kegelradgetriebe 1 über eine mittels eines nicht dargestellten Stellgliedes betätigbare Formschlußkupplung 2, bei welcher eine Schaltmuffe 3, die auf einer zu einem Achskegelrad 4 drehfest verbindbaren und zum Differentialgehäuse formschlüssigen Führungshülse 5 mitsamt von ihr umfaßten Schaltgliedern 6 auf der Nabe 7 des Achskegelrades 4 zu diesem axial verschieblich ist. Der Außenumfang des Achskegelrades 4, welches sich im Eingriff mit einem Ausgleichskegelrad 8 befindet, ist etwa durchmessergleich mit seiner Nabe 7, in welche im Bereich des Zahnkranzes 9 rillenförmige Ausnehmungen 10 in axialer Richtung eingearbeitet sind, welche dadurch die am Achskegelrad 4 außen angearbeitete Zylinderfläche 11 ähnlich einer Mitnahmeverzahnung unterteilen. In bevorzugter Ausführung dienen die Zahnlücken selbst als Ausnehmungen 10. Die die Nabe 7 umschließende Führungshülse 5 ist im Bereich der Ausnehmungen 10 mit Kugelführungslöchern 12 versehen, in welchen die Schaltglieder 6 axial verschieblich sind. Die Schaltglieder 6 (z. B. Kugeln) werden dabei in Umfangsrichtung durch die sie überdeckende Schaltmuffe 3 gesichert. Eine in Richtung des Achskegelrades 4 divergierende Konusfläche 13 im Innendurchmesser der Schaltmuffe 3 ermöglicht es, die Schaltglieder 6 nach Erreichung der Ausnehmungen 10 mit weichem Übergang in die Ausnehmungen 10 einzurasten und mit erhöhter Kraft festzuhalten. Bei der Rückwärtsbewegung ermöglicht diese Konusfläche 13 die rasche Lösung aus dem Formschluß.In Fig. 1, the bevel gear 1 has a form-locking clutch 2 which can be actuated by means of an actuator (not shown ) , in which a gearshift sleeve 3 , which is connected to an axle bevel gear 4 in a rotationally fixed manner and form-fitting guide sleeve 5 together with the switching elements 6 encompassed by it, on the hub 7 of the axle bevel gear 4 is axially displaceable to this. The outer circumference of the axle bevel gear 4 , which is in engagement with a differential bevel gear 8 , is approximately of the same diameter as its hub 7 , into which groove-shaped recesses 10 are machined in the axial direction in the region of the toothed ring 9 , which thereby produce the cylindrical surface 11 machined on the outside of the axle bevel gear 4 subdivide similar to a drive toothing. In a preferred embodiment, the tooth gaps themselves serve as recesses 10 . The guide sleeve 5 surrounding the hub 7 is provided in the region of the recesses 10 with ball guide holes 12 , in which the switching elements 6 are axially displaceable. The switching elements 6 (e.g. balls) are secured in the circumferential direction by the switching sleeve 3 covering them. A conical surface 13 diverging in the direction of the axle bevel gear 4 in the inner diameter of the shift sleeve 3 makes it possible to engage the shift members 6 after reaching the recesses 10 with a smooth transition into the recesses 10 and to hold them in place with increased force. During the backward movement, this conical surface 13 enables the quick release from the positive connection.
Die Führungshülse 5 kann erfindungsgemäß auch gleichzeitig als Lagerstuhl für das Lager des Achskegelrades 4 in der Wand des Kegelradgetriebes 1 mitverwendet werden, wenn die Anwendung für ein Differentialgetriebe erfolgt.According to the invention, the guide sleeve 5 can also be used at the same time as a bearing bracket for the bearing of the axle bevel gear 4 in the wall of the bevel gear 1 when the application is for a differential gear.
Durch den im Innendurchmesser der Nabe 7 gewonnenen Platz ist es nunmehr einfach, ein Wellengelenk 15 der vom Achskegelrad 4 abgehenden Gelenkwelle 16 zentrumsnah in das Getriebe zu integrieren, wie dies aus der DE-OS 34 46 271.6 im Prinzip bereits bekannt ist.Due to the space gained in the inner diameter of the hub 7 , it is now easy to integrate a shaft joint 15 of the drive shaft 16 coming from the bevel gear 4 close to the center into the transmission, as is already known in principle from DE-OS 34 46 271.6.
Mittels eines in die Nabe einsteckbaren und dort arretierbaren Sperringes 17 kann sowohl das Wellengelenk 15 axial arretiert als auch das Lager 14 durch eine Lagerabdeckung 18 schmutz- und beschädigungssicher abgedeckt werden.By means of a locking ring 17 which can be inserted into the hub and locked there, both the shaft joint 15 can be axially locked and the bearing 14 can be covered in a dirt and damage-resistant manner by a bearing cover 18 .
Die besondere bauliche Zusammenfassung des Kegelrades 4 und einer besonders großen Nabe 7 mit diese außen umfassenden großen Lager 14 ergibt die weitere Möglichkeit, das Kegelrad 4 samt Nabe 7 durch einen seitlichen Gehäusedeckel 19 in das Getriebe 1 einzuschieben bzw. es diesem wieder zu entfernen, ohne dazu eventuell weitere Getriebeteile, wie z. B. das Ausgleichskegelrad 8 oder die Führungshülse 5, ebenfalls ausbauen zu müssen.The special structural combination of the bevel gear 4 and a particularly large hub 7 with these large bearings 14 encompassing the outside gives the further possibility of inserting the bevel gear 4 together with the hub 7 through a side housing cover 19 into the gear 1 or removing it again without it possibly further gear parts such. B. the differential bevel gear 8 or the guide sleeve 5 , also need to be removed.
Sofern die als Laufbahn des Gelenkes 15 dienende Nabe 7 getrennt vom Kegelrad 4 hergestellt werden muß, besteht auch die Möglichkeit einer Stumpfschweißverbindung (20), wie z. B. eine Reibschweißung.If the hub 7 serving as the raceway of the joint 15 has to be produced separately from the bevel gear 4 , there is also the possibility of a butt weld connection ( 20 ), such as, for. B. a friction weld.
In Fig. 2 ist sowohl eine die Nabe 7 des Achskegelrades 4 umfassende Führungshülse 5.4 mit länglichen Führungslöchern 12.1 über dem Bereich der Ausnehmungen 10 auf den Außenmantel des Achskegelrades 4 vorgesehen als auch eine weitere, die muffenseitige Hälfte des Kegelradgetriebes 1 außen umfassende Führungshülse 5.1 vorgesehen, mit deren stirnseitiger und zum Achskegelrad konvergierender Führungsfläche 13.5 die Schaltglieder 6 durch die Muffe 3 radial von außen in Richtung zur Drehachse anpreßbar sind. Die Muffe 3 ist hier mit kreisrunden Führungslöchern 12.3 von etwas kleinerem Durchmesser als dem Durchmesser der Schaltglieder 6 entspricht versehen, so daß die Schaltglieder 6 käfigartig seitlich und radial geführt sind, gleichgültig ob sie in ihrer an das Kegelgetriebe 1 nabenartig anschließenden inneren Führungshülse 5.4 bzw. deren länglichen Führungslöchern 12.1 in die Ausnehmungen 10 des Achskegelrades 4 eingerastet oder (wie in der Fig. dargestellt) aus ihnen durch die Muffe 3 auf eine weitere, nach außen divergierende Führungsfläche 13.1 in der inneren Führungshülse 5.4 herausgeschoben sind.In FIG. 2 both the hub 7 of the Achskegelrades 4 comprehensive guide sleeve 5.4 is provided with elongated guide holes 12.1 provided above the region of the recesses 10 on the outer shell of the Achskegelrades 4 and further, the sleeve-side half of the bevel gear 1 provided externally extensive guide sleeve 5.1, with the end face and converging to the axle bevel gear guide surface 13.5, the switching elements 6 can be pressed radially through the sleeve 3 from the outside in the direction of the axis of rotation. The sleeve 3 is provided here corresponds with circular guide holes 12.3 of a somewhat smaller diameter than the diameter of the switching elements 6, so that the switching members are guided cage-like laterally and radially 6, regardless of whether they in their hub-like adjoining the bevel gear 1 inner guide sleeve 5.4 and whose elongated guide holes 12.1 are engaged in the recesses 10 of the axle bevel gear 4 or (as shown in the figure) are pushed out of them through the sleeve 3 onto a further, outwardly diverging guide surface 13.1 in the inner guide sleeve 5.4 .
In Fig. 3 ist für die Schaltglieder 6 anstelle von Kugeln eine besondere Art von Schaltfingern vorgesehen. Deren muffenseitiges Ende weist einen oben in eine Innenringnut der Schaltmuffe 3 eintauchenden balligen Nocken und das kegelradseitige Ende eine scheibenförmige Verdickung auf, welche (wie auch die Kugeln nach Fig. 2) zwischen axialen Führungsflächen 13.1 und 13.5 radial und axial begrenzt verschieblich und drehgesichert geführt sind. Der Einlegehub erfolgt primär beim Entlanggleiten an den hülsenseitigen Führungsflächen 13.1 und 13.5. Der Aushebehub wird noch unterstützt durch Entlanggleiten des mit Außenkonturen versehenen Rumpfes der Schaltfinger an den muffenseitigen Stirnkanten der inneren Führungsflächen 13.5.In Fig. 3, a special type of shift fingers is provided for the switching elements 6 instead of balls. Their sleeve-side end has a spherical cam which dips into an inner annular groove of the shift sleeve 3 and the bevel gear-side end has a disk-shaped thickening which (like the balls according to FIG. 2) is guided so as to be radially and axially displaceable and secured against rotation between axial guide surfaces 13.1 and 13.5 . The insertion stroke takes place primarily when sliding along the sleeve-side guide surfaces 13.1 and 13.5 . The lifting stroke is further supported by sliding along the outer contoured fuselage of the shift fingers on the socket-side end edges of the inner guide surfaces 13.5 .
Dank der hiermit auf beiden Seiten des Schaltweges wirksam werdenden, sanft wechselnden Führungsflächen wird, trotz der beengten Platzverhältnisse, in beiden Richtungen ein sicheres und weiches Umschalten erreicht.Thanks to this, effective on both sides of the switching path becoming, gently changing guide surfaces, despite the cramped space, a safe and secure in both directions soft switching achieved.
