Abstract
A camshaft () is provided for a stroke-variable valve drive of an internal combustion engine with a carrier shaft () and a cam part () that is arranged locked in rotation and movable in the axial direction on the carrier shaft and that is assembled from a cam carrier () and a sleeve (). The cam carrier has a cam group () of directly adjacent cams () with different cam strokes and an adapter end () on which the sleeve is mounted. The sleeve has a setting groove () in the form of a groove that extends across an extent of the sleeve and that is used for the specification of an axial setting groove track for an activation pin () moving the cam part on the carrier shaft. The setting groove is produced in the sleeve through non-metal-cutting shaping of sheet-metal material.
