Description
Die Erfindung betrifft ein Getriebe gemäß dem Oberbegriff von Anspruch 1. Ferner betrifft die Erfindung eine schaltbare formschlüssige Kupplung für ein solches Getriebe.The invention relates to a transmission according to the generic term of claim 1. Furthermore, the invention relates to a switchable positive coupling for such Transmission.

Aus der Praxis ist ein Sperrdifferentialgetriebe bekannt, bei welcher ein vor oder zurück antreibbarer Elektromotor über eine Schnecke ein Zahnrad einer Spiralfederanordnung antreibt, die ihrerseits über Zahnräder eine Zahnstange vor oder zurück antreibt, welche mit einer Schaltgabel bewegungsfest verbunden ist zum Einrücken bzw. Ausrücken eines axial beweglichen Kupplungsteiles in bzw. aus einem axial festen Kupplungsteil.From practice is a limited slip differential in which a forward or back drivable electric motor via a Worm drives a gear of a coil spring assembly, which in turn via gears a Rack forward or back drives, which is immovably connected to a shift fork to indent or disengage an axially movable coupling part in or out of an axial fixed coupling part.

Durch die Erfindung soll die Aufgabe gelöst werden, eine Vorrichtung für die Betätigung einer schaltbaren formschlüssigen Kupplung zu schaffen, welche konstruktiv einfacher ist, weniger Bauraum benötigt und eine vereinfachte Montage ermöglicht auch dann, wenn die Kupplung für die Übertragung von großen Drehmomenten ausgebildet ist und während des Einrückvorganges große Einrückwiderstände, insbesondere durch nicht oder nicht genau fluchtende Stellungen zwischen den miteinander zu kuppelnden Kupplungselementen und Kupplungslücken bestehen, und/oder beim Ausrücken der Kupplung große Haftreibungswiderstände durch große zu übertragende Drehmomente bestehen.By the invention, the task to be solved a device for the operation a switchable positive locking To provide a coupling which is structurally simpler, less Space required and a simplified assembly allows even if the Clutch for the transmission of great Torques is formed and during the engagement process size Indenting resistors, in particular by not or not exactly aligned positions between the consist of coupling elements to be coupled and coupling gaps, and / or on disengagement the clutch big Friction resistance through big ones to be transferred Torques exist.
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale von Anspruch 1 gelöst.This object is achieved according to the invention the features of claim 1 solved.
Durch die Erfindung wird die Anzahl der Bauteile wesentlich reduziert und die Montage vereinfacht sowie der für die Betätigungsvorrichtung der schaltbaren formschlüssigen Kupplung erforderliche Bauraum wesentlich verkleinert. Als Stellantrieb können zwar pneumatische oder hydraulische Elemente verwendet werden, jedoch ist auch statt dessen ein elektrischer Stellantrieb, beispielsweise in Form eines Elektromotors oder eines elektromagnetischen Linearantriebes möglich, so daß auch kleinere Fahrzeuge, welche keine Druckluftversorgung oder Hydraulikversorgung haben, mit einer schaltbaren formschlüssigen Kupplung bzw. einer Vorrichtung zur Kupplungsbetätigung ausgerüstet werden können.By the invention, the number the components significantly reduced and simplifies the assembly and the for the actuator the switchable positive locking Clutch required space significantly reduced. As an actuator can Although pneumatic or hydraulic elements are used, however is also instead an electric actuator, for example in the form of an electric motor or an electromagnetic linear drive possible, so that too smaller vehicles, which no compressed air supply or hydraulic supply have, with a switchable positive coupling or a Device for clutch actuation equipped can be.
