Abstract
A valve train for actuating a gas exchange valve of an internal combustion engine includes a camshaft configured to be driven by a crankshaft of an engine and including a camshaft tube. At least one cam support including a plurality of cam profiles is disposed on the camshaft so as to be rotationally engaged and axially displaceable with respect to the camshaft. A switching shaft is disposed in the camshaft tube and is configured to rotate together with the camshaft tube. A dog operatively connects the at least one cam support to the switching shaft. A displacement piece is connected to the switching shaft and is configured to be rotationally engaged with and axially displaceable on the camshaft tube. The displacement piece is actuatable so as to rotate the switching shaft relative to the camshaft tube and displace the cam support relative to the camshaft tube using the dog.
