Abstract
A gear shift mechanism of a change speed gearbox is provided that is constructed as an auxiliary transmission, in which all the transmission gears can be shifted by the simultaneous closing of two synchronizer clutches, with one synchronizer clutch participating in the shifting of all of the transmission gears. This synchronizer clutch is actuated by a servo drive, and the other synchronizer clutches are actuated purely mechanically via a shift roller.
