Variable valve train for a lifting valve, in particular for a gas exchange valve of an internal combustion engine, which valve can be moved periodically indirectly by way of a cam via a rocker arm between a closed and an open position, comprising (a) a camshaft, having at least one first cam and at least one second cam (4, 5) which is arranged offset in the longitudinal direction of the camshaft, the at least one first cam and the at least one second cam (4, 5) being of different design in terms of their cam contour; (b) a rocker arm which is mounted such that it can be pivoted about a rocker arm axis, which rocker arm is assigned to the at least one first cam via a roller at its camshaft-side end and is operatively connected to at least one lifting valve at its valve-side end; (c) a roller lever which is assigned to the at least one second cam (4, 5) via at least one roller at its camshaft-side end and is articulated at its other end on the rocker arm such that it can be pivoted about the rocker arm axis, (d) a switchable hydraulic locking device, by way of which the rocker arm and the roller lever can optionally be locked rigidly to one another, both following the movement of the at least one second cam (4, 5), or be unlocked from one another, both following the respectively associated cams (3, 4, 5) independently of one another, characterized (a) in that the roller lever is connected to the rocker arm via a hinge (14, 24, 25); and/or (b) in that the rocker arm and the roller lever in each case have a pivot pin seat (14, 24), which pivot pin seats (14, 24) are aligned with respect to one another and have an inserted pivot pin. (a) a camshaft, having at least one first cam and at least one second cam (4, 5) which is arranged offset in the longitudinal direction of the camshaft, the at least one first cam and the at least one second cam (4, 5) being of different design in terms of their cam contour; (b) a rocker arm which is mounted such that it can be pivoted about a rocker arm axis, which rocker arm is assigned to the at least one first cam via a roller at its camshaft-side end and is operatively connected to at least one lifting valve at its valve-side end; (c) a roller lever which is assigned to the at least one second cam (4, 5) via at least one roller at its camshaft-side end and is articulated at its other end on the rocker arm such that it can be pivoted about the rocker arm axis, (d) a switchable hydraulic locking device, by way of which the rocker arm and the roller lever can optionally be locked rigidly to one another, both following the movement of the at least one second cam (4, 5), or be unlocked from one another, both following the respectively associated cams (3, 4, 5) independently of one another, be locked rigidly to one another, both following the movement of the at least one second cam (4, 5), or be unlocked from one another, both following the respectively associated cams (3, 4, 5) independently of one another, (a) in that the roller lever is connected to the rocker arm via a hinge (14, 24, 25); and/or (b) in that the rocker arm and the roller lever in each case have a pivot pin seat (14, 24), which pivot pin seats (14, 24) are aligned with respect to one another and have an inserted pivot pin.
