V-drive and slide element for the same

A slide element for a wedge drive with a slide element receptacle and a drive element between which the slide element is to be placed;

• the slide element comprising:
• a dovetail-shaped side, which has a dovetail-shaped section with a plurality of sliding surfaces and is embodied to engage in a correspondingly dovetail-shaped receptacle of the slide element receptacle;
• a first plurality of the sliding surfaces on the slide element, by means of which forces are transmitted during a working stroke during which the slide element is moved outward between the drive element and the slide element receptacle, are arranged at an angle to each other, in a roof shape relative to each other, and have sliding plates;
• and
• the first plurality of sliding surfaces on the slide element, by means of which forces are transmitted during the working stroke, are larger than a second plurality of the sliding surfaces on the slide element, by means of which forces are transmitted during the return stroke during which the slide element receptacles is moved away from the drive element,
• wherein the slide element has a head rail, which is detachably fastened to the slide element and, as part of the dovetail-shaped side of the slide element, forms the second plurality of sliding surfaces on the dovetail-shaped section, by means of which forces are transmitted during the return stroke during which the slide element receptacle is moved away from the drive element.
