Description
Die Erfindung betrifft ein Ausgleichsgetriebe nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a differential gear according to the type defined in more detail in the preamble of
Die
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde ein Ausgleichsgetriebe mit einer Sperre zu schaffen, welches in axialer Richtung kompakt baut.The present invention is based on the object of creating a differential gear with a lock which is compact in the axial direction.
Die Aufgabe wird mit einem auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Ausgleichsgetriebe gelöst.The object is achieved with a generic differential gear which also has the characterizing features of the main claim.
Erfindungsgemäß weist das Ausgleichsgetriebe eine Sperre zum Sperren der Ausgleichswirkung auf, welche Lamellen aufweist, wobei die Lamellen in drehfester Verbindung mit einem Achskegelrad stehen. Die Lamellen können direkt mit dem Achskegelrad verbunden sein, es besteht jedoch auch die Möglichkeit die Lamellen über einen mit dem Achskegelrad drehfest verbundenen Lamellenträger zu haltern. Eine Betätigungseinrichtung weist einen Betätigungskolben auf, wobei die Betätigungseinrichtung hydraulisch oder elektromechanisch betätigt sein kann und wobei der Betätigungskolben auf der einen Seite des Ausgleichsgetriebes und die Lamellen auf der anderen Seite des Ausgleichsgetriebes angeordnet sind, wodurch ein Ausgleichskegelrad zwischen dem Betätigungskolben und den Lamellen angeordnet ist. Die Kraftübertragung vom Kolben zu den Lamellen erfolgt über mindestens einen Bolzen oder mehrere Bolzen, welche gleichmäßig am Umfang verteilt sind, wobei innerhalb des Bolzens eine Feder angeordnet ist, um den Kolben bei Nichtbetätigung in seine Ausgangslage zurückzudrücken. Vorzugsweise ist der Bolzen in einer Öffnung innerhalb des Differenzialkorbes angeordnet, wobei die Öffnung radial unterhalb des mit dem Differenzialkorb verbundenen Tellerrades angeordnet ist. Der Differenzialkorb ist über zwei Lagerstellen in einem Gehäuse gelagert, wobei innerhalb dieses Gehäuses der Kolben angeordnet ist. Vorzugsweise ist der Kolben radial außerhalb einer dieser Lagerstellen angeordnet. In einer weiteren Ausgestaltungsform bei hydraulischer Betätigung ist der Kolben über eine Membrandichtung von der Hydraulikflüssigkeit getrennt, wobei die Membrandichtung innerhalb des Gehäuses angeordnet ist und mit dem Gehäuse einen Kolbenraum bildet.According to the invention, the differential gear has a lock for locking the compensating effect, which lock has lamellae, the lamellae being in a rotationally fixed connection with an axle bevel gear. The lamellae can be connected directly to the bevel gear, but there is also the possibility of holding the lamellae via a lamella carrier connected to the bevel gear in a rotationally fixed manner. An actuating device has an actuating piston, wherein the actuating device can be actuated hydraulically or electromechanically and wherein the actuating piston is arranged on one side of the differential gear and the lamellas are arranged on the other side of the differential gear, whereby a differential bevel gear is arranged between the actuating piston and the lamellas. The power transmission from the piston to the lamellae takes place via at least one bolt or several bolts, which are evenly distributed around the circumference, a spring being arranged inside the bolt in order to push the piston back into its starting position when not actuated. The bolt is preferably arranged in an opening within the differential cage, the opening being arranged radially below the ring gear connected to the differential cage. The differential cage is mounted in a housing via two bearing points, the piston being arranged within this housing. The piston is preferably arranged radially outside one of these bearing points. In a further embodiment with hydraulic actuation, the piston is separated from the hydraulic fluid via a diaphragm seal, the diaphragm seal being arranged within the housing and forming a piston chamber with the housing.
In einer weiteren Ausgestaltungsform der Erfindung sind die Lamellen über einen Lamellenträger drehfest mit dem Achskegelrad verbunden, wobei der Lamellenträger radiale und axiale Bohrungen aufweist, um Schmiermittel zu den Lamellen zu bringen. Vorzugsweise weist der Differenzialkorb unterhalb der Lagerstelle im Bereich des Achskegelrades und des Lamellenträgers eine Schraubennut auf, über welche Schmiermittel zu den Bohrungen im Lamellenträger gefördert wird. Vorzugsweise ist die Schmiernut schraubenförmig ausgeführt.In a further embodiment of the invention, the disks are non-rotatably connected to the bevel gear via a disk carrier, the disk carrier having radial and axial bores in order to bring lubricant to the disks. The differential cage preferably has a screw groove below the bearing in the area of the bevel gear and the disk carrier, via which lubricant is conveyed to the bores in the disk carrier. The lubrication groove is preferably designed helically.
