Patent ID: 7418884

Claim:
A shifting device for shifting a transmission, the shifting device comprising: an axially slidable shifting shaft ( 2 ) supporting a plurality of shifting forks ( 8 , 10 , 12 , 14 ) which are each one of axially slidable relative to the shifting shaft ( 2 ), when the shifting fork ( 8 , 10 , 12 or 14 ) is blocked, and carried axially along with the shifting shaft ( 2 ), when the shifting fork ( 8 , 10 , 12 , 14 ) is selected, for carrying out a desired shifting procedure, a selection apparatus ( 28 , 30 , 32 , 42 , 44 , 46 ) for selecting a desired one of the plurality of shifting forks ( 8 , 10 , 12 , 14 ) to carry out the shifting procedure, and blocking apparatuses ( 52 ) for preventing movement of non-selected shifting forks ( 8 , 10 , 12 , 14 ), the blocking apparatuses ( 52 ) being supported on a substantially parallel, additional shaft ( 46 ), a first actuator ( 60 ) being provided, which axially displaces the shifting shaft ( 2 ) for carrying out the shifting procedure, elements of the selection apparatus ( 42 , 44 ) being supported on the additional shaft ( 46 ), and an additional actuator ( 48 ) being provided for rotating the additional shaft ( 46 ) and selecting the desired one of the plurality of shifting forks ( 8 , 10 , 12 , 14 ) to slide axially along with the shifting shaft ( 2 ) and for prevention of axial movement of the non-selected shifting forks ( 8 , 10 , 12 , 14 ) as the shifting shaft ( 2 ) slides axially.
