Abstract
A device for a valve train for switching over the lift of gas-exchange valves of an internal combustion engine comprising a camshaft on which at least one cam carrier with at least three different cam profiles is mounted so as to be non-rotatable and axially movable. The device includes an adjustment shaft arranged parallel to the camshaft and on which a first transmission element is mounted so as to be non-rotatable and axially movable, the first transmission element having a guide unit, a housing-fixed first guide element operatively connected to the guide unit, a second guide element operatively connected, on the one hand, to the guide unit and, on the other hand, to the cam carrier via a second transmission element, the second transmission element being connected to the cam carrier so as to be axially unmovable, and a push element operatively connected to the first transmission element.
