Abstract

See full text

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.
