Planetary gear e.g. spur gear for gearbox device used in powertrain of vehicle, has ring gear that is frictionally engaged with planter carrier by activation of clutch device on friction region of planet carrier

摘要

The planetary gear (1) has a coupling element (9) that is rotationally fixed with planet carrier (3). The coupling element is displaced along axial direction by actuation of adjusting element (10) with respect to common rotation axis (6) of connection element (11) such that coupling element is releasably connected to planet carrier and ring gear (5). The connecting element in planet carrier is axially displaced. The ring gear is frictionally engaged with planter carrier by activation of clutch device (8) on friction region (13) of planet carrier.
