Title: GEAR SHIFTING DRUM ARRANGEMENT AND MOTOR VEHICLE DRIVE TRAIN
Abstract:
Gear shifting drum arrangement (30) for a motor vehicle drive train (10), in particular a double clutch transmission drive train, having a first gear shifting drum (32) which is mounted rotatably about a rotational axis (36) and which has at least one circumferential first gear shifting contour (38) for at least one first shifting clutch (40), having a first electric motor (48) which is coupled to the first gear shifting drum (32), in order to drive the first gear shifting drum (32) in at least one rotational direction, having a second gear shifting drum (34) which is mounted rotatably about the rotational axis (36) and which has at least one circumferential second gear shifting contour (42) for at least one second shifting clutch (44), and having a second electric motor (62) which is coupled to the second gear shifting drum (34), in order to drive the second gear shifting drum (34) in at least one rotational direction. Here, the first gear shifting drum (32) is coupled to the first electric motor (48) via a first planetary gear set arrangement (58) and/or the second gear shifting drum (34) is coupled to the second electric motor (62) via a second planetary gear set arrangement (70).
