Abstract
A device (10) for axially moving a gearbox element (12), including: a shift drum (50) mounted rotatably about an axis of rotation (8) and having a shifting groove (62) formed in its outer casing at least partially circumferentially about the axis of rotation (8), which groove is axially inclinded (64) at least in some areas, a cage (30) holding the gear shift drum (50) with a cage wall (34) delimiting an inner cage space (48) against an outer cage space and a wall slot (70) extending axially through the cage wall (34) and opening the inner cage space (48) towards the outer cage space, a carriage (42) held axially movably between the gear shift drum (50) and the cage wall (34) in the area of the wall slot (70), and a shift fork (46) with two fork legs (80).
Claims21
A device (10) for axially moving a gearbox element (12), comprising:
- a gear shift drum (50) mounted rotatably about an axis of rotation (8) and having a shifting groove (62) formed in its outer casing at least partially circumferentially about the axis of rotation (8), which groove is axially inclinded (64) at least in some areas,
- a cage (30) holding the gear shift drum (50) with a cage wall (34) delimiting an inner cage space (48) against an outer cage space and a wall slot (70) extending axially through the cage wall (34) and opening the inner cage space (48) towards the outer cage space,
- a carriage (42) held axially movably between the gear shift drum (50) and the cage wall (34) in the area of the wall slot (70), and
- a shift fork (46) with two fork legs (80), between which the gearbox element (12) can be positively received for axial movement in the axial direction (2) and a guidance pin (78) which is connected to the fork legs (80) and is inserted into the shifting groove (62) guided through the wall slot (70) and the carriage (42),
- characterised in that the shifting groove (62) is moulded into the gear shift drum (50) with a closed curve.
