    专利说明:

    [001] The invention relates to a screwing element, according to the description of claim 1 of the patent.
    [002] Said screwing element, in the form of a coupling element, can be considered as known, for example, from the document WO 2010/014881 Al. The screwing element comprises a threaded rod. Furthermore, the screwing element comprises a head connected to the rod. The head has a tool-engaging portion having six uniformly distributed angle domes in the peripheral direction of the head. The angle cups, in turn, have respective flanks, by means of which the head can be brought into positive cooperation with an internal hexagon of a tool, for tightening the tightening element.
    [003] Said tool is constituted, for example, by a key box, which has a socket that has a tool-engaging portion in the form of a hexagon or double hexagon. This double hexagon or hexagon is constituted by an internal hexagon, in which the tool-engaging portion or the flanks of the screwing elements can be at least partially arranged.
    [004] The flanks of the tightening element can thus cooperate positively with the hexagonal socket of the tool, so that the torques for tightening and tightening the tightening element can be transmitted from the tool to the tightening element. By using the tool, a person can therefore, for example, screw or tighten the screw element. Between the angle domes, in the circumferential direction, respective recesses are arranged. This means that, respectively, two successive angle domes, in the peripheral direction of the head, are spaced apart by a recess arranged between said angle domes.
    [005] The object of the present invention is to develop a tightening element of the type indicated in the introduction, so that a particularly low weight of the tightening element can be perceived, and that the tightening element can be used in a particularly flexible.
    [006] This object is achieved by a bolting element that has the characteristics described in claim 1 of the patent. Advantageous embodiments are defined in the other claims which comprise convenient and non-trivial developments of the present invention.
    [007] In order to develop a tightening element of the type defined in the text of claim 1 of the patent, in such a way that a particularly low weight and particularly flexible applicability or the function of the tightening element can be realized, it is provided, according to with the invention, that the flanks of the angle domes are respectively provided, at least partially, with a radius. 9, it is therefore possible, in particular, to bring the screwing element through the flanks of the angle domes, either in positive cooperation with a traditional hexagon socket of a tool, for tightening the screwing element, or in positive cooperation with a, so called surface movement mechanism, in order to tighten the screwing element, in which the spokes in the flanks serve for the vertical absorption of forces. In other words, the screwing element according to the invention can be screwed securely by means of different tools.
    [008] As a result of the spokes on the angle domes, a socket wrench can, for example, be particularly advantageously applied, or placed in operative connection with the tool-engaging portion of the screwing element. Furthermore, as a result of the angle radii, a particularly advantageous force flow can be represented, so that the tightening element can be tightened without damage even with high torques.
    [009] The bolting element can thus be configured as a hex flange bolt, in particular for passenger vehicles and commercial vehicles, which is optimized in terms of weight and installation space and which can be installed or assembled with traditional hexagon or double hexagon box keys and by means of a surface movement mechanism.
    [0010] Another possibility of realizing a particularly low weight of the tightening element is to provide a so-called cavity arrangement in the central part of the head of the tightening element. This means that it is preferably provided that, in the radial direction of the stem, a recess (cavity) of the head is arranged between the angle domes. Positioning the cavity in the circumferential direction between the angle cups merely helps to obtain a particularly low weight of the screwing element.
    [0011] Furthermore, it is possible to reduce the height of the head by at least substantially 17 percent, compared to a traditional screwing element, without, however, changing the height of the collar. Furthermore, a reduction in the overall height can be obtained, so that the weight of the screwing element can be kept particularly low. Also reducing the height of the collar compared to a traditional screwing element represents a possibility of reducing weight.
    [0012] Advantages, features and additional details of the invention will be shown through the description below, of a preferred illustrative embodiment based on the attached figures. The characteristics and combinations of characteristics indicated in the above description, as well as the characteristics and combinations of characteristics indicated below in the description of the figures, and/or characteristics and combinations of characteristics shown only in the figures, can be used not only in the respectively defined combination, but also in other combinations or alone, without departing from the scope of the invention.
    [0013] The drawings show in: - Figure 1, a schematic perspective view of a screw element for an automotive vehicle, comprising a rod having a thread and comprising a rod connected to said head having an engagement portion at tool having six angle domes arranged and evenly distributed in the peripheral direction of the head and having respective flanks, through which the head can be brought into positive cooperation with an inner hex of a tool, for tightening the screwing element, in which the respective recesses are peripherally arranged between the angle domes, and wherein the flanks of the angle domes are respectively provided with at least partially a radius; - figure 2, a schematic side view of the screwing element; figure 3, selectively, a schematic sectional view of the screwing element along a section line A-A shown in figure 2; - figure 4, a schematic top view of the screwing element; - figure 5, a schematic and enlarged representation of a region, indicated with B in the figure. 4, of the screwing element; - figure 6, a schematic and perspective side view of a tool having an internal hexagon for tightening the screwing element; and - figure 7, a schematic longitudinal sectional view of the tool.
    [0014] Figures 1 and 2 show a screwing element, indicated in its entirety by number 10. The screwing element 10 is constituted by a fastening element, by means of which, for example, a first component can be fastened to a second component of an automotive vehicle. The screwing element 10 has a shank 12 which has a thread in the form of an external thread 14, as well as a head 16 connected to the shank 12. The screwing element 10 is made, for example, of a metallic material. The head 16 is configured in one piece with the shank 12. In the direction of the longitudinal extension of the shank 12, a collar 18 is configured between the head 16 and the shank 12. The screwing element 10 can in this case be supported by means of the glue 18 with respect to the first component, in order to, in the tight state of the screwing element 10, fix the first component to the corresponding second component.
    [0015] As can be seen in Figure 1, the head 16 has a tool-engaging portion 20, which is configured as an external polygon. The tool-engaging portion 20 has six angle domes 22 which are arranged evenly distributed in the peripheral direction of the head 16. In other words, the angle domes 22 are arranged in pairs, equally spaced apart, in the circumferential direction of the head 16 The angle domes 22 have respective flanks 24, 26. In other words, each of the angle domes 22 has a flank 24 and a flank 26. The tangential planes of the flanks 24, 26 of the respective angle dome 22 form an angle 120 degrees. This is particularly evident from Figure 5, where the tangential planes are indicated by 28 and 30.
    [0016] Through flanks 24, 26, the head 16 can be brought into positive cooperation with a hexagon socket of a tool, in order to screw or tighten the screw element 10. Said tool is constituted, for example, by a socket 32, as illustrated in Figures 6 and 7, which has an internal polygon 34 as the tool-engaging portion. The inner polygon 34 can be configured, for example, as an inner hexagon. The tool-engaging portion 20, configured as an outer polygon, of the bolting element 10 can thus be positioned, at least partially, on the corresponding inner polygon 34. The inner polygon 34 can positively cooperate with the flanks 24, 26 , so that the torques can be transmitted from the socket 32 to the screw element 10 through the tool-engaging portion 20.
    The socket 32 further has a socket opening 36, through which the socket 32 can be placed over a socket wrench and can thus be positively connected to the socket wrench. Through the use of the socket wrench, the socket 32 and the tool-engaging portion 20, a person can therefore, for example, screw or tighten the screw element 10 with high torques.
    [0018] In particular, it is possible that the tool-engaging portion 20 can be brought into positive cooperation with the standard inner hex, internal double hexagons and with a surface moving tool, in order to tighten the screwing element 10, via standard hexagon socket or surface moving tools.
    [0019] In figure 2, a large number of measurements R1, R2, dc, C, k and k' of the tightening element 10 can be seen. In Figure 3, additional measurements df, pf, R3, ds, dw of the tightening element 10 can be seen. It can be seen, particularly clearly, in figures 1 and 4, that respective recesses 38 are arranged in the circumferential direction between the angle domes 22. It can further be seen that the head 16 has a support ring 40, which in turn has a dfa diameter. The diameter dfa is constituted by the outer diameter of the load-bearing ring for the angle domes 22. In figure 4, it can be seen that said outer diameter, i.e. the diameter dfa of the support ring 40, is particularly large and not have interruptions.
    [0020] Between the angle domes 22, in the radial direction, a central cavity in the form of the so-called cavity arrangement 42 of the head 16 is provided. The weight of the screwing element 10 can in this case be kept particularly low. Furthermore, the flanks 24, 26 of the respective corner dome 22 are connected to one another in the circumferential direction by a transition region 44. This means that the respective corner dome 22 has rounded corners or slopes. In figure 4, the so-called width between the WAC corners and the width between the WAF faces of the tool-engaging portion 20 are also shown. The width between the WAC corners thus indicates the distance of the rounded ends of two angle domes 22 that are positioned, opposite each other, in the radial direction of the rod 12.
    [0021] In figure 5 it can be seen that the flanks 24, 26 of the angle cups 22 are respectively provided, at least partially, with a radius R. In other words, the flanks 24, 26 are not, for example, configured flat in shape, but preferably flanks 24, 26 extend along a circular arcuate segment 46, shown in Figure 5, which has radius R. particularly advantageously with the surface-moving mechanism or with a surface-moving tool. The corresponding radius R on the respective flank 24 or 26, in this case, ensures vertical absorption of the forces emanating from the surface moving tool.
    [0022] Preferably, it is provided that the height of the head 16, i.e. the so-called head height, shown here by measurement K, is substantially reduced by at least 17 percent, relative to a screw element traditional. Measure C means the height of the necklace 18.
    [0023] In the screwing element 10, furthermore, it is provided that - as can be seen in Figure 5 - the angle domes 22 merge with the respective recesses 38 through, in the present case, the respective arcuate and shaped base regions concave shape 48.
    [0024] The pf measurement indicates the depth, developing in the direction of the longitudinal extension of the rod 12, of the cavity arrangement 42, and the df measurement indicates the diameter, developing in the radial direction of the rod 12, of the cavity arrangement 42. The design of the cavity arrangement 42 is preferably designed with due regard for the maximum loads that occur on the head 16, in particular during the screwing and unscrewing process. The preservation of the measure K' at the corners of the tool coupling portion 20, whose preservation is provided in relation to a traditional screwing element, guarantees a secure assembly when using traditional hexagon or double hexagon socket wrenches, as well as the height required for the use of surface movement tools.
    [0025] The head 16 has in the circumferential direction, between the angle domes 22, recesses 38. The depth of the recesses 38 extends all the way to the load-bearing ring 40, responsible for transmitting the force. The measure df also indicates the internal diameter of the load-bearing ring 40. The thickness, better said, the wall thickness of the load-bearing ring 40, is designed for the loads occurring. The measure k' therefore indicates the height of the distinct transition region 44 of the angle domes 22.
