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).
Claims12
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 inclined (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),
- wherein the shifting groove (62) is molded into the gear shift drum (50) and the shifting groove (62) is elliptically formed in the gear shift drum (50) such that the shifting groove (62) is separated into an upper shifting groove part and a lower shifting groove part.
