Abstract
A camshaft may comprise a main shaft, on which at least two sliding cam pieces are accommodated in a rotationally fixed and axially displaceable manner, wherein the sliding cam pieces each comprise a carrier tube, on which are seated cam groups each comprising at least two cam tracks for valve-control purposes, as well as an adjustment element that can be brought into operative connection with an actuator for axial displacement of the two sliding cam pieces. A method for assembling such a camshaft may involve providing a module body with bearing bridges that receive the camshaft in a rotatable manner, inserting a first sliding cam piece into a first bearing bridge, connecting the first sliding cam piece to the adjustment element, inserting a second sliding cam piece into a second bearing bridge, and connecting the second sliding cam piece to the adjustment element with the aid of an axial adjustment distance of at least one of the sliding cam pieces in the bearing bridges.
