The invention relates to a sliding cam system, comprising at least one sliding cam, which is arranged in a rotationally fixed but axially displaceable manner on at least one axially fixed base shaft of a reciprocating-piston internal combustion engine in order to form a camshaft, at least one actuating device for moving the sliding cam into different axial positions by means of at least one actuating pin that can reach into at least one displacement groove on the periphery of the sliding cam, wherein the actuating device has a machine-fixed housing and the displacement groove is formed in a high circle jacket (4) of the sliding cam down to a groove base (7, 8) and is helical and has an insertion region, a displacement region having an accelerating flank and a braking flank, and a retraction region for the actuating pin, wherein an extended engagement region (9 or 10, 11 or 12) is associated with the displacement groove (5, 5a or 6, 6a) and the extended engagement region (9 to 12) at least partially has a material removal from the level of the high circle jacket (4) in the direction of the groove base (7 or 8). |
