    摘要: A valve drive for activation of gas exchange valves of internal combustion engines, with which valve stroke switching is accomplished with little effort, a low construction height, and at low switching forces. Incorrect switching and damage to the camshaft during valve stroke switching are avoided, even at high engine speeds of rotation. An adjustment shaft that is rotatable by the camshaft and parallel to the camshaft has two adjustment devices rotatably disposed on it, along with two tappets between the adjustment devices. The tappets are connected with a shift gate for valve switching between two different cam profiles of a cam package that is axially displaceable on the camshaft. The tappets each have a contour that contacts the adjustment devices via a guide pin. A gear wheel engages with a gear segment on the camshaft, via a drive on the adjustment shaft, to rotate the adjustment shaft.

    摘要: A variable valve drive for internal combustion engines is used for activation of gas exchange valves, in which the gas exchange valves engage different cam profiles of a camshaft driven by the crankshaft of the internal combustion engine. The camshaft has at least one displaceable cam segment that carries multiple different cam profiles having the same base circle section. Each one of the cam profiles is switched to be active for the related gas exchange valve, in accordance with the axial position of the cam segment relative to at least one related gas exchange valve. The axial positioning of the cam segment takes place by a setting shaft that can be rotated and is disposed parallel and next to the camshaft. The setting shaft has a guide track in which a tappet is guided, which acts on a transfer element that determines the axial position of the cam segment.
