Abstract
Die Erfindung betrifft ein Ausgleichsgetriebe (1) eines Kraftfahrzeugs, mit einer eine Lamellenkupplung aufweisenden Ausgleichssperre (2) zur Sperrung eines Drehzahlausgleichs zwischen Rädern einer Antriebsachse, wobei die Lamellenkupplung der Ausgleichsperre von einem Aktuator derart betätigbar ist, dass ein variables Drehzahlverhältnis zwischen den Rädern der Antriebsachse einstellbar ist, wobei der Aktuator einen Elektromotor (3) und ein auf Lamellen der Lamellenkupplung einwirkendes Betätigungselement (4) aufweist, welches eine Drehbewegung des Elektromotors in eine Linearbewegung zur Betätigung der Lamellenkupplung umsetzt. Erfindungsgemäß treibt der Elektromotor (3) das Betätigungselement (4) direkt bzw. unmittelbar an.The invention relates to a differential (1) of a motor vehicle having a differential lock having a multi-plate clutch (2) for blocking a speed compensation between wheels of a drive axle, wherein the multi-plate clutch of the differential lock of an actuator is actuated such that a variable speed ratio between the wheels of the drive axle is adjustable, wherein the actuator has an electric motor (3) and acting on slats of the multi-plate clutch actuator (4), which converts a rotational movement of the electric motor into a linear movement for actuating the multi-plate clutch. According to the invention, the electric motor (3) drives the actuating element (4) directly or directly.
Description
Die Erfindung betrifft ein Ausgleichsgetriebe eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The The invention relates to a differential gear of a motor vehicle the preamble of claim 1.
Ausgleichsgetriebe von Kraftfahrzeugen werden auch als Differentialgetriebe bezeichnet, wobei Ausgleichsgetriebe unterschiedliche Drehzahlen an Antriebsrädern z. B. bei einer Kurvenfahrt oder bei Unebenheiten der Fahrbahn ausgleichen sollen, um so das Drehmoment auf die Antriebsräder gleichmäßig zu verteilen. Ausgleichsgetriebe verfügen über Ausgleichssperren, um unter gewissen Bedingungen die Wirkungen des Ausgleichsgetriebes ganz oder teilweise aufzuheben. So kann mit Ausgleichssperren bei einer Fahrt auf einer glatten oder weichen Fahrbahn ein Drehzahlausgleich zwischen den Antriebsrädern einer Antriebsachse gesperrt werden, um so ein Durchdrehen von angetriebenen Rädern zu vermeiden.differential of motor vehicles are also referred to as differential gear, wherein differential gear different speeds of drive wheels z. B. when cornering or unevenness of the road so as to evenly distribute the torque to the drive wheels. differential have balancing locks, under certain conditions, the effects of the differential gear to be lifted in whole or in part. So can with balancing locks at a ride on a smooth or soft road a speed compensation between the drive wheels be locked to a drive axle, so a spin of driven Wheels too avoid.
Aus
der
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Ausgleichsgetriebe eines Kraftfahrzeugs zu schaffen. Dieses Problem wird durch ein Ausgleichsgetriebe gemäß Anspruch 1 gelöst. Erfindungsgemäß treibt der Elektromotor das Betätigungselement direkt bzw. unmittelbar an.Of these, Based on the present invention, the problem underlying to create a novel differential gear of a motor vehicle. This problem is solved by a differential according to claim 1 solved. According to the invention drives the electric motor, the actuator directly or directly to.
Im Sinne der hier vorliegenden Erfindung treibt der Elektromotor des Aktuators das Betätigungselement desselben, welches vorzugsweise als Kugelrampenmechanismus ausgeführt ist, direkt bzw. unmittelbar an. Der Elektromotor ist hierzu in das Ausgleichsgetriebe, insbesondere in die Ausgleichssperre, integriert, so dass kein oder nur geringer zusätzlicher Bauraum für den Elektromotor benötigt wird. Des Weiteren entfällt das bei aus dem Stand der Technik bekannten Ausgleichsgetrieben benötigte Getriebe zwischen dem Elektromotor und dem Betätigungselement.in the In the sense of the present invention drives the electric motor of Actuator the actuator the same, which is preferably designed as a ball ramp mechanism, directly or directly to. The electric motor is for this purpose in the differential gear, especially in the balancing lock, integrated, so no or only small additional Space for the electric motor needed becomes. Furthermore, deleted in known from the prior art differential gears needed Transmission between the electric motor and the actuator.
Nach einer vorteilhaften Weiterbildung der Erfindung ist das Betätigungselement als ein zwei zusammenwirkende Rampenscheiben aufweisender Kugelrampenmechanismus ausgebildet ist, wobei ein Läufer des Elektromotors integraler Bestandteil einer der beiden Rampenscheiben ist.To An advantageous development of the invention is the actuating element as a ball ramp mechanism having two cooperating ramp discs is formed, being a runner the electric motor integral part of one of the two ramp discs is.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ausführungsbeispiele der Erfindung werden, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert.preferred Further developments of the invention will become apparent from the dependent claims and the following description. Embodiments of the invention without being limited to this to be closer to the drawing explained.
