Gear shifting drum for a variable-speed gearbox

The invention relates to a gear shifting drum for a gear shifting device of variable-speed gearboxes for motor vehicles, with an outer surface area of the cylindrical gear shifting drum having at least one curved path for form-fitting guidance of an engagement member of a gearshift fork, wherein the gearshift fork is connected to a gearshift sleeve of a synchronization device which is arranged for axial displacement between two gears on a gearbox shaft disposed in parallel relation to the gear shifting drum. A gear shifting drum () for a gear shifting device of variable-speed gearboxes for motor vehicles has a curved path (to ) for guiding an engagement member () of the gearshift fork (to ), wherein the gearshift fork (to ) is directly connected to a synchronization device. According to the invention, at least one radially outwardly directed wall () is arranged on the outer surface area () of the gear shifting drum () for formation of the curved path (to ).
