Vorrichtung zur Steuerung der Drehphase

摘要

An apparatus for controlling a rotational phase is disclosed. The apparatus comprises an input member (3) provided so as to be rotatable, an output member (1) co-axially provided with the input member (3) so as to be rotatable, a planetary gear mechanism (10) co-axially provided with the input member (3) and the output member (1) for connecting the input member (3) with the output member (1), the planetary gear mechanism (10) including three elements, namely a sun gear (11), a planetary carrier (12) supporting planetary gears (13) and a ring gear (14), a drive apparatus (20) connected with one of the three elements of the planetary gear mechanism (10) for shifting a rotation phase, the drive means including two members (21,23) which are rotatable with respect to each other. One of the input member (3) and the output member (1) is connected with the ring gear (14), and the other of the input member (3) and the output member (1) is connected with the planetary carrier (12). The two members of the drive apparatus (20) are co-axially provided with the planetary gear mechanism (10). One of the two members (21,23) is secured to the fixed side, and the other of the two members (21,23) is connected with the sun gear (11).
