ABSTRACT:
A shifting device for the shifting of a transmission with a shifting shaft (2), having a multiplicity of shifting forks or shifting levers (8, 10, 12, 14) placed in an axial slidable manner for the carrying out of a shifting procedure with a selection apparatus (28, 30, 32, 42, 44, 46) for the choice of a shifting fork (8, 10, 12, 14) from the multiplicity of shifting forks for the carrying out of the shifting procedure and with blocking disk (52) for the prevention of the movement of non-chosen shifting forks (8, 10, 12, 14). The elements (2, 8, 10, 12, 14, 20, 22) for the carrying out of the shifting procedure are made from a material of high structural strength and the elements of the selection apparatus (28, 30, 32, 42, 44, 46) and the blocking apparatus (52) are constructed from a material of lesser structural strength.
