Sliding cam system for an internal combustion engine, comprising an integrated locking element

A sliding cam system for an internal combustion engine, the sliding cam system comprising:

• at least one camshaft, an adjustment element and at least one actuator, wherein the at least one camshaft comprises a carrier shaft with a primary sliding cam element and at least one secondary sliding cam element, each of which is arranged so as to be displaceable axially relative to the carrier shaft and each comprises a shift gate with at least one shift groove, and wherein the at least one actuator has at least one actuator pin which engages in the at least one shift groove of the shift gate of the primary sliding cam element according to the necessary switch position of the at least one camshaft, and wherein the adjustment element is arranged parallel to a longitudinal axis of the carrier shaft and is axially displaceable in the direction of the longitudinal axis of the carrier shaft and has at least two coupling pins, wherein a first coupling pin of the at least two coupling pins is arranged in the region of the primary sliding cam element and a second coupling pin of the at least two coupling pins is arranged in the region of the at least one secondary sliding cam element and the first and second coupling pins cooperate with the shift gate of the respective primary and at least one secondary sliding cam elements such that the adjustment element transmits a movement of the primary sliding cam element initiated by the at least one actuator pin to the at least one secondary sliding cam element,
• wherein a locking element on the primary sliding cam element is configured at least for locking the adjustment element between at least two position changes such that the locking element is displaceable axially along the longitudinal axis of the carrier shaft, the locking element formed inside the at least one shift groove,
• and at least one abutment element is formed in contact with the locking element and configured to be non-displaceable and rotationally fixed relative to and radially spaced from the carrier shaft at least for receiving axial forces transmitted by the locking element;
• wherein the at least one abutment element is formed on the at least one actuator axially next to the at least one actuator pin;
• wherein the locking element is in the form of one of a circular disc and ring disc having a cutout defined therein that permits movement of the abutment element through the cutout.
