Module for a variable-lift valve train of an internal combustion engine

A preassembled module for a variable-lift valve train configured to be installed within a cylinder head of an internal combustion engine, the preassembled module comprising:

• a base plate configured to attach the preassembled module to the cylinder head;
• an electric linear actuator arranged on an upper longitudinal side of the base plate;
• a slide plate having:
• a first retaining wall extending below a lower longitudinal side of the base plate;
• at least one actuating finger extending below and from the first retaining wall, the at least one actuating finger configured to move in a first longitudinal direction to move a coupling slide of a switchable rocker arm;
• a first longitudinal side and a second longitudinal side;
• one of the first or second longitudinal sides slidably engaging a third longitudinal side of the base plate, and the first and second longitudinal sides of the slide plate are parallel to the third longitudinal side of the base plate;
• and,
• a contact wall extending from the third longitudinal side of the base plate toward an actuating end of the electric linear actuator such that the contact wall extends above the upper longitudinal side of the base plate;
• and
• actuation of the contact wall by the electric linear actuator moves the contact wall in the first longitudinal direction such that:
• i) the one of the first or second longitudinal sides slidably moves against the third longitudinal side in the first longitudinal direction, and ii) the at least one actuation finger moves in the first longitudinal direction;
• and
• the contact wall, slide plate, and at least a portion of the at least one actuating finger move in unison in the first longitudinal direction.
