    Abstract: A preassembled module for a variable-lift valve drive of an internal combustion engine is provided for installation into a cylinder head. The module has a base plate with an electric linear actuator which lies on an upper side of the base plate. A guide plate, which lies on the upper side, has an outer side wall arranged to guide a slide piece. The guide piece extends below the base plate two downwardly pointing actuating fingers. Each respective actuating finger has a contact surface for moving a transverse coupling slide of a switchable rocker arm. The slide piece has a bracket which protrudes over the guide plate with a contact landing arm which runs transversely relative to the electric linear actuator. An actuator-side end of the contact landing arm is in contact with an actuating pin of the electric linear actuator to move the slide piece.

    Abstract: A pre-assembled module for a variable-stroke valve drive of an internal combustion engine is provided. The module includes a base plate having at least one projecting guide plate, an e-linear actuator positioned on the projecting guide plate, and a longitudinally guided push rod with two adjusting fingers extending along a wall of the guide plate. Each respective adjusting finger has a contact surface for displacement of a transverse coupling slide of a switchable cam follower. A rocker arm, having first and second arms, is suspended on an underside of the base plate; the first arm in contact with an adjusting pin of the linear actuator; and, the second arm in contact with the push rod for displacement thereof in a first direction. A spring means for displacement of the push rod in a second direction is arranged between the push rod and the guide plate.
