Abstract
A two-stage planetary gear drive,-shifting device having an input shaft (1) which is connected with a sun gear (12) and an output shaft (2) which is connected to a planetary gear carrier (15), hollow internal gear (18), of the planetary gear drive, is form-fit, by a slide collar (19), to either a gear drive housing (3) or is coupled to the gear (12). The slide collar (19), is coaxial with the input drive shaft and is slidable into various shift positions by an electrical positioning member (31). It is proposed that the electrical positioning member (31) is an electromagnet, and an armature (33) of the electromagnet is connected, in a driving manner, with the slide collar (19).
