Abstract: A camshaft includes a carrier shaft which can be mounted rotatably along a shaft axis and at least one cam pack disposed axially displaceably on the carrier shaft. The cam pack includes at least two cams and at least one adjusting member for axial adjustment of the cam pack. The cams and the at least one adjusting member are connected to one another in an axially adjacent configuration and can be mounted axially displaceably as a composite structure in a direct configuration on the carrier shaft. A method for producing a camshaft and a cam pack are also provided.

Abstract: A valve train for an internal combustion engine includes a camshaft with a cam unit for actuating a gas exchange valve. The cam unit has at least two cam paths arranged axially one behind the other and is arranged on the camshaft in a rotation-resistant and axially displaceable manner, and has an actuating profile interacting with a displaceable actuating element between a home position and an actuating position radially to the axis of the camshaft for axially displacing the cam unit on the camshaft. The actuating profile is formed by the lateral front face of the cam unit, and the actuating element has at least one displaceable actuating pin that interacts with a lateral front face of the cam unit such that an axial displacement of the cam unit takes place and in each axial position a different cam path is activated to actuate the gas exchange valve.
