Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Stirnraddifferential.The invention relates to a spur gear differential.
Hintergrund der ErfindungBackground of the invention
Ein Differential ist ein Ausgleichsgetriebe umfassend ein Planetengetriebe, das vornehmlich in Kraftfahrzeugen zwischen den angetriebenen Rädern zum Einsatz kommt. Da die Räder einer Achse beim Fahren in einer Kurve unterschiedlich lange Wege zurücklegen, wird über ein solches Differential die Möglichkeit gegeben, dass sich die Umfangsgeschwindigkeiten der gekoppelten Räder frei einstellen können, so dass beide Räder die gleiche Kraft übertragen können. Differentiale sind in unterschiedlicher Bauart bekannt, eine besonders zweckmäßige Ausgestaltung ist die eines Stirnraddifferentials, wie es beispielsweise aus
Wenngleich derartige Differentiale es ermöglichen, dass sich die Raddrehzahlen unabhängig voneinander entsprechend der Weglängen der jeweiligen Fahrspur einstellen können und auch eine symmetrische Antriebsmomentverteilung auf beide Antriebsräder möglich ist, so ist ein Nachteil insbesondere bei Anwendung im Kraftfahrzeugbereich dahingehend gegeben, als dann, wenn die Kraftschlusspotentiale der beiden Antriebsräder unterschiedlich sind, die Vortriebskräfte, die von beiden Antriebsrädern jeweils auf die Fahrbahn übertragbar sind, jeweils von dem Antriebsrad abhängig sind, dass das geringere Moment erhält, mithin also die geringere Kraft überträgt. D. h., dass in bestimmten Situationen, beispielsweise wenn auf Glatteis eines der Räder durchdreht, das andere, auf einem griffigen Untergrund stehende Rad ein kaum höheres Moment erhält als das durchdrehende. Ein Anfahren kann dann beispielsweise schwierig oder unmöglich sein.Although such differentials make it possible that the wheel speeds can be set independently of each other according to the path lengths of the respective lane and a symmetrical drive torque distribution to both drive wheels is possible, so a disadvantage in particular when used in the motor vehicle sector is given to than when the traction potentials Both drive wheels are different, the propulsive forces that are transferable from both drive wheels on the road, each dependent on the drive wheel that receives the lower torque, thus therefore transmits the lower power. This means that in certain situations, for example when one of the wheels is spinning on ice, the other wheel standing on a grippy ground receives a barely higher moment than the spinning one. A start can then be difficult or impossible, for example.
Zu diesem Zweck ist die Ausgestaltung eines Differentials als Sperrdifferential bekannt. Unter einem Sperrdifferential versteht man ein Differentialgetriebe, das eine konstruktiv bewusst schwergängige, behinderte Ausgleichsbewegung zulässt. D. h., dass eine gewisse Grundkopplung zwischen den beiden Radseiten auch dann gegeben ist, wenn das eine Rad oder die eine Achse infolge schlechter Bodenhaftung kein Moment oder nur ein geringes Moment überträgt. Infolge der gegebenen, auf ein gewisses Niveau gesperrten Kopplung ist es in solchen Fällen möglich, dass das Differential das Antriebsmoment von einem durchrutschenden Rad auf das Rad mit der besseren Bodenhaftung überträgt und so die Traktion verbessert wird. Auch beim Anfahren mit starker Beschleunigung, z. B. auf einer bevorrechtigten Straße, wird hierüber verhindert, dass das kurveninnere Rad abhebt und so durchdreht, so dass die Leistung auf die Straße geleitet und das Fahrzeug sicher in den Verkehr eingefädelt werden kann, beispielsweise im Bereich von Einmündungen. Auch läuft grundsätzlich eine gesperrte Achse immer besser gerade aus als eine ungesperrte, weshalb sich unter Verwendung eines solchen Sperrdifferentials die Wirkung beispielsweise von Seitenwind oder der Bernoulli-Effekt beim schnellen Vorbeifahren an einem LKW reduzieren lässt.For this purpose, the embodiment of a differential is known as a limited slip differential. A limited-slip differential is understood to mean a differential gear that allows a constructively deliberately stiff, disabled compensating movement. That is to say that a certain basic coupling between the two wheel sides is also given if the one wheel or the one axle transmits no moment or only a slight moment as a result of poor ground adhesion. Due to the given coupling locked to a certain level, it is possible in such cases that the differential transmits the drive torque from a slipping wheel to the wheel with better traction and thus improves the traction. Even when starting with strong acceleration, z. As on a privileged road, this prevents the inside wheel lifts and so crazy, so that the power can be directed to the road and the vehicle can be safely threaded into the traffic, for example in the area of junctions. In principle, a locked axle is always better straight than an unlocked, so using such a locking differential can reduce the effect of, for example, crosswinds or the Bernoulli effect when driving fast on a truck.
Auch bei hohen Querbeschleunigungen, beispielsweise bei sportlich gefahrenen Kurven, zeigen sich ebenfalls die Vorteile des Sperrdifferentials. Denn mit ihm kann verhindert werden, dass das kurveninnere und damit entlastete Rad schlupft und ebenso schnell oder sogar schneller als das kurvenäußere Rad dreht, so dass stets ein Leistungsfluss auf die Straße gegeben ist. Zwar ist infolge der auf einen gewissen definierten Wert eingestellten Grundsperrung des Differentials die freie Anpassung der Raddrehzahlen an die Weglänge der Fahrspur behindert, jedoch sind die Vorteile solcher Sperrdifferentiale in kritischen Fahrzuständen beachtlich.Even with high lateral accelerations, for example in sporty driven curves, also show the benefits of the limited slip differential. Because it can be prevented that the inside wheel and thus relieved wheel slips and turns just as fast or even faster than the outside wheel, so that there is always a power flow on the road. Although the free adjustment of the wheel speeds to the path length of the lane is hindered as a result of the set to a certain defined value basic locking of the differential, but the benefits of such limited slip differentials in critical driving conditions are considerable.
Um eine solche drehmomentunabhängige Grundsperrung zu erzielen ist es bekannt, mehrere Reibscheiben zu integrieren, die die freie Beweglichkeit der Abtriebe, also der Sonnenräder, behindern. In das anfangs schon erwähnte Stirnraddifferenzial nach

Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt somit das Problem zugrunde, ein Differential, insbesondere in Form eines Stirnraddifferentials, mit Sperrwirkung anzugeben, das demgegenüber verbessert ist.The invention is therefore based on the problem of specifying a differential, in particular in the form of a spur gear, with blocking effect, which is improved in contrast.
Zur Lösung dieses Problems sind erfindungsgemäß das Federmittel und das Axiallager zwischen den beiden Sonnenrädern angeordnet, wobei das Federmittel am einen Sonnenrad und das Axiallager am anderen Sonnenrad anliegt, während zwischen jedem Sonnenrad und dem Planetenradträger jeweils eine Reibscheibe angeordnet ist. Es kommen also zwei Reibscheiben zum Einsatz, die jeweils die Relativbewegung eines Sonnenrads zum Planetenradträger beeinflussen. Das Federmittel nebst Axiallager befindet sich zwischen den Sonnenrädern, spannt diese also in Richtung der Planetenradträger vor, mithin also gegen die Reibscheiben. Da über das Axiallager eine freie Verdrehbarkeit der Sonnenräder zueinander sichergestellt ist, wird folglich das Federmittel nicht reibend beansprucht.To solve this problem, the spring means and the thrust bearing between the two sun gears are arranged according to the invention, wherein the spring means abuts a sun gear and the thrust bearing on the other sun gear, while between each sun gear and the planet carrier in each case a friction disc is arranged. So there are two friction plates used, each affecting the relative movement of a sun gear to the planet. The spring means together with thrust bearing is located between the sun gears, so this biases in the direction of the planet carrier, thus against the friction plates. Since a free rotatability of the sun gears to each other is ensured via the thrust bearing, consequently, the spring means is not subjected to rubbing.
Bei dem erfindungsgemäßen Differential, insbesondere in einer Bauform, wie sie aus
Darüber hinaus ist infolge der Entkopplung von Federmittel und Reibscheibe zwangsläufig keine auslegungsmäßige Abhängigkeit des Reibscheibendurchmessers gegeben. Dieser kann unter Ausnutzung des gesamten gegebenen radialen Bauraums den Anforderungen entsprechend gewählt werden.In addition, due to the decoupling of spring means and friction disc inevitably no interpretive dependence of the friction disc diameter is given. This can be selected by taking advantage of the total given radial space requirements.
Als Federmittel kommt bevorzugt wenigstens eine Tellerfeder, bevorzugt ein Tellerfederpaket bestehend aus mehreren hintereinander geschalteten Tellerfedern zum Einsatz, wobei insbesondere bei Verwendung eines Tellerfederpakets eine große Bandbreite hinsichtlich der Variation der Vorspannkraft gegeben ist.As a spring means is preferably at least one plate spring, preferably a disc spring assembly consisting of several successively connected disc springs are used, in particular when using a plate spring package is given a wide range in terms of the variation of the biasing force.
Das Axiallager selbst ist bevorzugt ein Nadellager, das axial gesehen sehr wenig aufbaut, so dass folglich hierfür wenig Bauraum vorgehalten werden muss.The thrust bearing itself is preferably a needle bearing, which, viewed axially, builds up very little, so that consequently little space must be kept for this purpose.
