Definitions

• the invention relates to a slider element for a wedge drive with a slider element receptacle and with a driver element, between which the slider element is to be arranged, wherein the slider element has a dovetail-shaped side with a dovetailed portion having sliding surfaces, for engaging in a corresponding dovetailed receiving the slider element receiving is formed, wherein those first sliding surfaces on the slide member, are transferred via the forces during the working stroke, during which the slider element between the driver element and the slider element receiving is moved outward, respectively at an angle to each other and are arranged in roof shape to each other and sliding plates , and wherein these first sliding surfaces on the slider element, via which forces are transmitted during the working stroke, are larger than those second sliding surfaces on the slider element, over which For example, forces at the rearward stroke during which the slider element receiver is removed from the driver element are transmitted.
• the invention is therefore based on the object, starting from the above-described prior art, a slider element to simplify design to facilitate their installation.
• the slider element should ensure a high wear resistance and a jamming linear motion.
• the second sliding surfaces on the dovetailed portion on the forces at the rear hub, during which the slider element receiving is removed from the driver element transmitted can be dispensed with a symmetrical and L-shaped arrangement of sliding plates to form the dovetail shape.
• the head rail according to the invention can simultaneously provide for those second sliding surfaces which are required for forming the dovetail shape on the slider element.
• a slider member having high durability and good guiding properties can be provided.
• the slider element can be relatively maintenance-friendly accessible maintenance, when the head rail is releasably secured to the slider element.
• the construction in the region of the attachment of the head rail on the slide element can be further simplified if the head rail is fastened with its rail foot in a, in particular T-shaped, groove on the slide element at least positively.
• the maintenance of the wedge drive can be further simplified if the sliding plates are releasably secured to the slider element.
• the slider element according to the invention can be used in a wedge drive with a slider element receptacle and with a driver element.
• sliding surfaces between the slider element and driver element can advantageously be provided, wherein a dovetail-like guide device is provided with sliding surfaces on the slider element and sliding surfaces on the slider element receiving between the slider element and the slider element receiving, wherein the dovetail-shaped portion of the slider element engages in a correspondingly dovetailed receiving the slider element recording, wherein On the sliding surfaces of the guide means on the slider element receiving each sliding plates symmetrically and in an L-shape, the narrow side facing inward, are arranged to form the dovetail shape.
• FIG. 1 is a sectional view of a wedge drive 1 in the transverse direction
• Fig. 2 is a three-dimensional view of the wedge drive of FIG. 1 in a partially torn view.
• FIGS. 1 and 2 a wedge drive 1 with a slide element receptacle 2, with a slide element 3 and with a driver element 5 connected to the slide element 3 is shown.
• Slider element 3 and slide element receptacle 2 are movably connected to one another via a dovetail-like guide device 6.
• the slider element 3 has a dovetail-shaped portion 30, which are associated with a plurality of mutually angled sliding surfaces 31, 32, 33, 34 to form the dovetail shape.
• the first sliding surfaces 32, 34 on the forces during the working stroke, during which the slide element 3 is moved between the driver element 5 and the slider element holder 2 to the outside, are transmitted, in each case at an angle to each other and are arranged in roof shape to each other.
• slide plates 37, 39 are provided and fastened via not shown screw releasably on the slider element 3 or connected.
• Other releasable connection means are further conceivable.
• a head rail 100 which also forms part of the dovetail-shaped side 30 of the slider element 3. This not only reduces the design effort on the slide element 3 but it also eliminates a significant installation effort on the slide element 3, because no sliding plates symmetrically and in an L-shape, the narrow side facing inward, must be arranged to form a dovetail shape.
• a head rail 100 in contrast to several disjoint sliding plates for a high mechanical strength and thus increases the stability of the slider element 3.
• the slider element receptacle 2 has a correspondingly shaped portion 20 with releasably secured sliding plates 26, 27, which form sliding surfaces 21, 22, 23, 24 on the slider element receptacle 2.
• the sliding plates 26, 27 are symmet- and in an L-shape, the narrow side facing inward, arranged to form the dovetail shape.
