Abstract
A mechanically controllable valve drive includes a gas exchange valve on which a transmission arrangement acts via a working contour. The transmission arrangement comprises a first wheel element comprising a toothing which is connected to a camshaft, and a second wheel element comprising a toothing which acts on the gas exchange valve. The transmission arrangement is mounted to move in a cylinder head via a bearing, and is operatively connected to the camshaft and to a valve stroke adjusting device comprising an adjusting shaft. The first and second wheel elements are each mounted to rotate on the adjusting shaft and to be in a geared connection with each another via their respective toothing so that a rotation of the adjusting shaft effects a phase shift between the first and second wheel elements and so that a rotary fixing generates an oscillating movement of the first and second wheel elements.
