Abstract
A shift mechanism for a gearbox has a shift actuation unit designed to produce an axial shifting motion, at least two selector forks for shifting gear components to shift gears, and at least one shift rod designed to transmit the axial shifting motion from the shift actuation unit to at least one of the at least two selector forks. The coupling mechanisms and the shift rods are positioned to be axially aligned with one another.

A gear-shifting mechanism for a transmission, comprising:
- a shift activation unit which is configured for generating an axial shifting movement;
- at least two shift forks for displacing transmission components for shifting gears;
- at least one shift rod which is configured for transmitting the axial shifting movement from the shift activation unit to at least one of the at least two shift forks;
- and
- at least two coupling mechanisms for selectively establishing a mechanical coupling between the shift activation unit and one of the at least two shift forks.
A method for shifting a gear in a transmission having a gear-shifting mechanism that comprises:
- a shift activation unit which is configured for generating an axial shifting movement;
- at least two shift forks for displacing transmission components for shifting gears;
- at least one shift rod which is configured for transmitting the axial shifting movement from the shift activation unit to at least one of the at least two shift forks;
- and
- at least two coupling mechanisms for selectively establishing a mechanical coupling between the shift activation unit and one of the at least two shift forks.
- the method comprising the steps of:
- establishing a mechanical coupling between the shift activation unit and one of the at least two shift rods;
- or
- establishing a mechanical coupling between the at least one shift rod and one of the at least two shift forks;
- and
- activating the shift activation unit so as to establish a gear-specific connection within the transmission by way of the specific shift fork.
