Switching device for 2-stage planetary drive has electromagnetic setting element controlling sliding cuff for coupling hollow wheel of planetary drive with drive housing or sun wheel

摘要

The switching device is used for a 2-stage planetary drive with a drive shaft (1) coupled to a sun wheel (12), a drive take-off shaft (2) coupled to a planetary carrier (15) and a hollow wheel (18) which is coupled to the drive housing (3) or the sun wheel via a sliding cuff (19). It uses an electromagnetic setting element (31) with an armature (33) coupled to the cuff, for displacing the latter between its switched positions.
