GEAR SHIFTING DRUM FOR A VARIABLE-SPEED GEARBOX

摘要

A gear shifting drum (2) for a gear shifting device of variable-speed gearboxes for motor vehicles has a curved path (11a to 11c) for guiding an engagement member (13) of the gearshift fork (12a to 12c), wherein the gearshift fork (12a to 12c) is directly connected to a synchronization device. According to the invention, at least one radially outwardly directed wall (9, 10) is arranged on the outer surface area (8) of the gear shifting drum (2) for formation of the curved path (11a to 11c).
