Abstract

A camshaft assembly, particularly for use in an internal combustion engine, having a shaft base body and a plurality of cam parts. In order to be able to selectively shut down individual cylinders, cam parts are provided with cams which are arranged so as to be rotationally fixed and axially displaceable in relation to the shaft base body. Depending on a desired sequence of axially fixed and axially displaceable cam parts, it is proposed to arrange the axially displaceable cam parts on a longitudinally extending profile in an axially displaceable manner and to push the axially fixed cam parts—insofar as these are necesary—over or across the receiving area for the axially displaceable cam parts and to secure them to the shaft.
