Abstract
Die vorliegende Erfindung betrifft eine Vorrichtung zur Verstellung einer Nockenwelle (1) einer Brennkraftmaschine mit innerer Verbrennung mit mindestens einem Elektromotor (8), der über ein Planetengetriebe die Verstellung der Nockenwelle (1) gegenüber einem Antriebsrad (2) bewirkt, wobei das Planetengetriebe ein erstes Hohlrad (3) und ein zweites Hohlrad (4) aufweist, sowie mindestens ein erstes Planetenrad (5), das mit dem ersten Hohlrad (3) in Eingriff steht und mindestens ein zweites Planetenrad (6), das mit dem zweiten Hohlrad in Eingriff steht und das fest mit dem ersten Planetenrad (5) verbunden ist. Eine effiziente Stellung mit geringen Verstellmomenten wird dadurch erreicht, dass mehrere Planetensätze (12) vorgesehen sind, die jeweils aus einem ersten Planetenrad (5) und einem zweiten Planetenrad (6) bestehen, dass das Antriebsrad (2) mit dem ersten Hohlrad (3) fest verbunden ist, dass die Nockenwelle (1) mit dem zweiten Hohlrad (4) fest verbunden ist, dass das erste Planetenrad (5) und das zweite Planetenrad (6) einen geringfügig unterschiedlichen Durchmesser aufweisen und dass das erste Planetenrad (5) und das zweite Planetenrad (6) auf einem Planetenträger (7) gelagert sind, der konzentrisch zur Achse der Nockenwelle (1) und des Antriebsrades (2) gelagert ist. The invention relates to a device for adjusting a camshaft (1) of an internal combustion engine with at least one electric motor (8), which causes the camshaft (1) to be adjusted relative to a drive wheel (2) via a planetary gear, the planetary gear being a first Ring gear (3) and a second ring gear (4), as well as at least a first planet gear (5), which is in engagement with the first ring gear (3) and at least a second planet gear (6), which is in engagement with the second ring gear and which is firmly connected to the first planet gear (5). An efficient position with low adjustment torques is achieved in that several planetary gears (12) are provided, each consisting of a first planet gear (5) and a second planet gear (6), that the drive gear (2) with the first ring gear (3) is firmly connected that the camshaft (1) is firmly connected to the second ring gear (4), that the first planet gear (5) and the second planet gear (6) have a slightly different diameter and that the first planet gear (5) and that second planet gear (6) are mounted on a planet carrier (7) which is mounted concentrically to the axis of the camshaft (1) and the drive wheel (2).
