Preamble of
In Kraftfahrzeugen mit einem Allradantrieb wird ein Zentraldifferentialgetriebe eingesetzt, um die Verteilung der Antriebskraft zwischen de Vorderachse und der Hinterachse zu steuern und/oder zu regeln. Das Zentraldifferentialgetriebe hat somit die Aufgabe, die Antriebsleistung auf die Vorderachse und die Hinterachse aufzuteilen. Bei einem Traktionsverlust an der Vorderachse oder an der Hinterachse ist eine Differentialsperre erforderlich, um die Traktion auf der jeweils anderen Achse zu erhalten. Als Differentialsperren werden beispielsweise Bremsen oder Reibungskupplungen eingesetzt. Nachteilig bei diesen Differentialsperren ist, dass dabei mechanische Energie ungenutzt vernichtet wird.In Motor vehicles with four-wheel drive will be a central differential used to distribute the driving force between the front axle and the rear axle to control and / or to regulate. The central differential gear thus has the task, the drive power to the front axle and split the rear axle. With a loss of traction on the front axle or at the rear axle a differential lock is required, to get the traction on the other axle. As differential locks For example, brakes or friction clutches are used. The disadvantage of these differential locks is that while mechanical Energy is destroyed unused.
