Abstract

The present invention relates to a sliding cam module for a camshaft, which comprises at least one sliding cam with at least one cam segment, comprising at least two cams with cam tracks that are different to one another as well as a closed bearing element, which is arranged on the sliding cam in a rotatable and axially non-displaceable manner for mounting the sliding cam, wherein the bearing element comprises a recipient area to hold at least one section of a locking device to lock the sliding cam in an axial position. Furthermore, the invention relates to a camshaft with at least one corresponding sliding cam module as well as a shaft, on which the sliding cam module is arranged in a rotationally fixed manner and can be moved in an axial direction along a longitudinal axis of the shaft and a cover module, which comprises a cylinder-head cover as well as a closed bearing element, which comprises a recipient area to hold at least one section of a locking device to lock the sliding cam in an axial position.
