Claim 17:
18. A transmission, including
a housing, and
a locking device,
wherein:
the locking device includes:
a sliding sleeve movably supported in the housing along a movement axis, and having an internal gearing, a central axis of the sliding sleeve being coaxial with the movement axis,
a first synchronizer body disposed coaxially with the sliding sleeve, the first synchronizer body having an external gearing configured to be bringable into engagement with the internal gearing of the sliding sleeve by moving the sliding sleeve along the movement axis, and having a first friction region,
a second synchronizer body disposed coaxially with the sliding sleeve, the second synchronizer body having an external gearing configured to be bringable into engagement with the internal gearing by moving the sliding sleeve along the movement axis, and having a second friction region,
a first synchronizer ring having an external gearing configured to be bringable into engagement with the internal gearing of the sliding sleeve by moving the sliding sleeve along the movement axis, and having a third friction region configured to abut against the first friction region of the first synchronizer body, and
a second synchronizer ring having an external gearing configured to be bringable into engagement with the internal gearing of the sliding sleeve by moving the sliding sleeve along the movement axis, and having a fourth friction region configured to abut against the second friction region of the second synchronizer body,
wherein the locking device is configured such that:
the sliding sleeve is configured to be bringable into a neutral position, in which the internal gearing of the sliding sleeve is not in engagement with the external gearing of the first synchronizer body and is not in engagement with the external gearing of the second synchronizer body while simultaneously being in engagement with the external gearing of only one of the first or second synchronizer rings, and
in a movement along the movement axis, the sliding sleeve is configured to be bringable into a synchronization position, in which the internal gearing of the sliding sleeve is not in engagement with the external gearings of the first or second synchronizer bodies and simultaneously the internal gearing of the sliding sleeve is partially in engagement with the external gearing of one of the first or second synchronizer rings such that tooth-heads and tooth-troughs of the internal gearing of the sliding sleeve and of the external gearing of said one of the first or second synchronizer ring are rotated by an angle relative to each other to apply an axial force to said one of the first or second synchronizer rings such that the corresponding synchronizer body is synchonizable with said one of the first or second synchronizer rings via frictional engagement, while also being in engagement with the external gearing of the other one of the first or second synchronizer rings such that the tooth-heads and tooth-troughs of the internal gearing of the sliding sleeve and of the external gearing of the other one of the first or second synchronizer rings are not rotated relative to each other, so that no axial force is applied to the other one of the first or second synchronizer rings via this tooth engagement.
