Wedge drive and method for producing a wedge drive having optimized guidance

A wedge drive designed to redirect a vertical pressing force into a horizontal, linear working motion, comprising a sliding element and a sliding element holder which are two guide elements on which a guide device with a sliding plate assembly with two side sliding plates and a central guide is arranged, wherein the side sliding plates are at a distance from one another in a transverse direction (Y) which is perpendicular to a sliding direction (X) of the side sliding plates, wherein the central guide is arranged between the two side sliding plates and is fastened on the sliding element, wherein the two side sliding plates are constructed with at least one shoulder which rests with an interlocking connection on a corresponding step formed on the guide element, wherein, for the lateral support of each side sliding plate, either another step is provided on the sliding element holder or another shoulder is provided on the side sliding plate with which an interlocking connection to the sliding element holder takes place, wherein the interlocking connection acts in or against the defined transverse direction so that transverse forces are caught and each side sliding plate rests with at least the following contact surfaces on the sliding element holder:

• a. a first contact surface of each side sliding plate that lies on a first plane (E1) and runs in the transverse direction (Y),
• b. a second contact surface that lies on a second plane (E2) at a distance from the first plane and also runs in the transverse direction (Y), and
• c. a third contact surface that runs perpendicularly to the latter, wherein the particular side sliding plates are fastened by fastening means to the sliding element holder and the fastening means are arranged in an area inside the particular first contact surface.
