Abstract

Die Erfindung betrifft eine Vorrichtung zur Verstellung einer Nockenwelle (11) einer Brennkraftmaschine mit innerer Verbrennung mit mindestens einem Elektromotor (3), der über ein Getriebe (12) die Verstellung der Nockenwelle (11) gegenüber einem Antriebsrad (10) bewirkt, wobei das Getriebe (12) einen Planetenträger (2) aufweist, auf dem mindestens ein Planetenrad (4) vorgesehen ist, das von einem Elektromotor (3) angetrieben ist. Eine schnelle Verstellung bei einfachem Aufbau kann dadurch erreicht werden, dass mehrere Planetenräder (4) vorgesehen sind, die mit einem Hohlrad (1) im Eingriff stehen und dass jedem Planetenrad (4) ein Elektromotor (3) zugeordnet ist, der dieses über eine gemeinsame Welle (6) antreibt.

Figure 00000001
The invention relates to a device for adjusting a camshaft (11) of an internal combustion engine with at least one electric motor (3), which causes the camshaft (11) to be adjusted relative to a drive wheel (10) via a gearbox (12), the gearbox (12) has a planet carrier (2) on which at least one planet gear (4) is provided, which is driven by an electric motor (3). A quick adjustment with a simple structure can be achieved in that several planet gears (4) are provided, which are in engagement with a ring gear (1) and in that each planet gear (4) is assigned an electric motor (3), which has a common one Drives shaft (6).
