A valve drive (1, 1′) of an
internal combustion engine with
stroke-variable gas-exchange valve activation is provided. The valve drive includes a
camshaft (2, 2′) with a carrier shaft (3) and a
cam piece (4, 4′) that is arranged in a rotationally locked way on the carrier shaft and that can move between axial positions and that has a
cam group of directly adjacent cams (14a-c, 15a-c) with different lobes and a groove-shaped axial link (16, 16′) and an activation element (18, 19) that can be coupled in the axial link for shifting the
cam piece on the carrier shaft. The cam piece is provided with a bearing journal (12, 13, or 12′) on which the
camshaft is supported in the radial direction at a
camshaft bearing point (9, 10, or 9′) of the
internal combustion engine. Here, the axial link is constructed overlapping with the camshaft bearing point on the bearing journal in the axial direction, and the activation element runs in the camshaft bearing point.
