Description

[0001] A wheel with a rim, a hub, and at least one flexible spoke.

[0002] The invention relates to a wheel with a rim, a hub and at least one flexible spoke that is essentially only subject to tensile force, wherein the rim has rim attachment means with a receiving structure for receiving a spoke and the hub has hub attachment means with a receiving structure for receiving a spoke, wherein the spokes run under tensile tension between one of the hub attachment means and one of the rim attachment means, so that the hub is held centrally within the circumference of the rim by the spokes.

[0003] Wheels of the aforementioned type are known, for example, from bicycle wheels. Such wheels can, of course, also be used in other ways, in other means of transportation and means of transport, in drive systems, in wind turbines, etc. In principle, very different applications of the wheels described here are conceivable.

[0004] Wheels, especially bicycle wheels, typically don't have flexible spokes, but rather rod-shaped wire spokes that are individually mounted between the rim and hub and then tensioned. However, flexible spokes have also been known for some years, for example, in the form of a tensile-resistant rope or cord. Highly tensile materials are suitable for these, such as aramids, polyethylene fibers, composites, and even metal; such spokes are sometimes also referred to as textile spokes. A flexible spoke is practically only capable of withstanding tensile stress and is dimensionally unstable under other loads, as is the case with a shoelace.The advantages of using flexible spokes include reduced weight, high wear and corrosion resistance, and in some cases, improved suspension behavior of the wheel.

[0005] The object of the present invention is to provide a wheel with flexible spokes that is simple in design, and in particular easy to assemble and maintain.

[0006] The aforementioned problem is solved in the wheel mentioned at the beginning primarily by using at least a portion of the spokes as flexible, continuous spokes. A flexible, continuous spoke is a closed, continuous tension member; it has no beginning and no end, and therefore no ends where, in the prior art, for example, mounting elements for attaching it to the rim or hub are located. The construction of the continuous spoke is thus simple, and the spoke itself is extremely lightweight.

[0007] Although different designs of the wheel can be most clearly explained using figures, the various preferred designs are explained in general terms below.

[0008] An endless spoke can form a plurality of flexible spokes, with each individual spoke, by definition, running under tension between one of the hub attachment points and one of the rim attachment points. Assuming a sufficient length of endless spoke, theoretically all the spokes of the wheel could be formed by a single endless spoke.

[0009] In a preferred embodiment, however, a majority of the wheel's spokes, in particular all of the wheel's spokes, are formed by several continuous spokes, especially identical continuous spokes, such that each of the multiple continuous spokes forms the same number of spokes. This results in a continuous spoke running between several rim attachment points and hub attachment points, forming the majority of the spokes. Each group of spokes is represented by a single continuous spoke. The use of multiple continuous spokes offers advantages in terms of assembly, operational reliability in the event of a spoke failure, and also in terms of stress distribution across all spokes when the wheel is fully assembled.

[0010] A further development of the previously described wheel is characterized by the fact that the spokes formed by an endless spoke, which thus run between a rim mounting point and a hub mounting point, are distributed rotationally symmetrically with respect to the wheel's center point. Therefore, if an endless spoke forms, for example, three spokes—or three groups of spokes, each with closely adjacent spokes—then these spokes—or spoke groups—occupy angular positions at 0°, 120°, and 240°. If an endless spoke forms four spokes—or four groups of spokes, each with closely adjacent spokes—then these spokes—or spoke groups—occupy angular positions at 0°, 90°, 180°, and 270°.In the event that the hub has a first spoke mounting flange and a second spoke mounting flange on opposite sides of the wheel plane defined by the rim, the hub attachment means are provided on both the first and the second spoke mounting flange. Preferably, the spokes running from the hub attachment means of the first spoke mounting flange to the rim attachment means, and the spokes running from the hub attachment means of the second spoke mounting flange to the rim attachment means, are formed by different continuous spokes.

[0011] In a preferred embodiment of the wheel, the distance between the first and second spoke mounting flanges, viewed in the axial direction of the hub, is adjustable, in particular by means of a linear guide formed between the hub axis and the spoke mounting flanges. The linear guide is preferably designed according to the model of a splined or toothed shaft connection. This measure allows the running path of the endless spokes between the rim mounting points and the hub mounting points to be changed in a technically simple and very effective manner, thereby also allowing the tensile stress in the spokes to be influenced uniformly and simultaneously.

[0012] Preferably, the endless spoke is guided around the receiving structure of the rim attachment and / or the receiving structure of the hub attachment such that the guidance of the endless spoke around the receiving structure of the rim attachment and / or the receiving structure of the hub attachment forms a friction-fit connection between the endless spoke and the respective rim attachment and / or the respective hub attachment. This effect occurs primarily under the always assumed tensile load. The frictional force of the friction-fit connection between the endless spoke and the respective receiving structure arises mainly only when the endless spoke is under tension, i.e., when the endless spoke conforms to the receiving structure under the influence of the tension.In this situation, normal forces act along the contact contour between the receiving structure and the endless spoke, generating the frictional force in the direction of the endless spoke's travel. The frictional force of the positive connection between the endless spoke and the respective receiving structure (i.e., the receiving structure of the rim attachment and / or the receiving structure of the hub attachment) is preferably generated to at least 90%, particularly preferably to at least 95%, and most preferably to at least 99% by the cable tension. A very small portion of the frictional force between the endless spoke and the receiving structure can be achieved by clamping the cable, for example, if a point-like mounting aid is provided on the receiving structure into which the endless spoke can be easily pressed to secure it during assembly.However, it is particularly advantageous if the frictional force between the endless spoke and the mounting structure is generated solely by cable tension (and not by clamping). Eliminating or minimizing clamping of the endless spoke has the advantage that the mechanical stress can be distributed evenly along its entire length.

[0013] Even if an endless spoke forms several spokes - i.e., direct connections between rim attachment means and hub attachment means - a single spoke can essentially be considered separately in terms of its forces.

[0014] In a particularly preferred embodiment, the rim attachment means is arranged on the rim such that the receiving structure of the rim attachment means is exposed in the rim's operational state, allowing the continuous spoke to be guided around the receiving structure of the rim attachment means for assembly. In other words, the continuous spoke can be mounted in the mechanically ready-to-use state of the rim without disassembling, splitting, or otherwise modifying the rim. This offers a significant advantage over wheel designs where mounting the flexible spoke requires disassembling the rim, for example, by splitting the rim into two parts (e.g., above and below the wheel plane defined by the rim).

[0015] According to a further embodiment of the wheel, the rim mounting element and / or the hub mounting element comprises at least one post element as a receiving structure, wherein the post element projects substantially from the wheel plane defined by the rim. Preferably, the rim mounting element and / or the hub mounting element comprises two post elements as a receiving structure, and particularly preferably, wherein the two post elements project substantially in opposite directions from the wheel plane. Preferably, the post elements have a thickened head to counteract the spoke slipping off the post element. According to another preferred embodiment, the surface of the post element is structured, at least in the contact area with the spoke, to achieve an increased coefficient of friction, at least compared to an unstructured surface.

[0016] In particular, if two post elements are present as a receiving structure, the two post elements are encircled in a lemniscate-like manner in a preferred embodiment, whereby a complete lemniscate does not have to be realized by the spoke guidance; the embodiment applies in particular to embodiments in which the post elements point outwards from the wheel plane in one direction.

[0017] Preferably, the endless spoke is guided around the respective post element in such a way that the realized wrap angle is greater than 180°.

[0018] If post elements projecting in opposite directions from the wheel plane are provided, then in a further developed embodiment of the wheel, the continuous spoke is provided that it at least partially encircles the first of the two post elements projecting in opposite directions from the wheel plane, then the continuous spoke is guided over an edge of the rim attachment element or an edge of the hub attachment element, and the spoke then at least partially encircles the second post element. As a result, three intensive contact points are created to achieve the frictional connection.

[0019] In an advantageous further development of the wheel using two post elements, the two post elements are arranged on a flat support structure of the rim mounting element or the hub mounting element, particularly wherein the flat support element is arranged substantially in the plane of the wheel or parallel to the plane of the wheel. In the case of the hub, the flat support structure is preferably formed by a flange on the hub. In the case of the rim, the flat support structure is formed by a flat part arranged on the inner circumference of the rim and oriented substantially towards the hub. The flat support elements, for example, sheet metal, are ideally suited for easily attaching, for example, screwable post elements.A further advantageous embodiment of the wheel is characterized in that the rim mounting element and / or the hub mounting element is designed in a mounting element plane in the wheel plane or substantially parallel to the wheel plane and has a suspension structure as a receiving structure for the continuous spoke, in which the continuous spoke is held in a fixed position under tensile load in the direction of tension. Preferably, the rim mounting element and / or the hub mounting element has two suspension structures.

[0020] In a further development of the aforementioned wheel, incorporating two mounting structures, the continuous spoke is guided into the first mounting structure from above the mounting plane, through the first mounting structure to below the mounting plane, then below the mounting plane to the second mounting structure, from below the mounting plane through the second mounting structure to above the mounting plane, and from there to the next rim mounting point or hub mounting point. By changing the spoke's path to the different sides of the mounting plane, the spoke automatically runs over the edges of the rim mounting point or hub mounting point, thus enhancing the frictional connection.

[0021] In a particularly simple implementation of the wheel, it is provided that the rim attachment means and / or the hub attachment means are designed flat with constrictions as receiving structures, in particular as a flat, anchor-shaped retaining element.

[0022] In a further advantageous embodiment of the wheel, a deflectable clamping element is formed on the rim attachment point and / or the hub attachment point, with which the running path of the endless spoke can be influenced, in particular in the area of ​​the rim attachment point and / or in the area of ​​the hub attachment point, so that the tension in the endless spoke can be influenced accordingly by means of the adjusting element. This considerably simplifies the assembly of the endless spoke.

[0023] In a further advantageous embodiment of the wheel, the clamping device is designed as an eccentric. A post element – ​​as previously described – can be designed as an eccentric. The clamping device can also be wedge-shaped, whereby, by shifting the wedge-shaped clamping device, a portion of the continuous spoke is guided over sections of the wedge at different heights, thus achieving the clamping effect. Furthermore, the clamping device can be designed to be transversely adjustable, in particular by means of at least one screw. For example, a structural element is conceivable that is held on a flat support of a connecting element and can be deflected by means of a screw.

[0024] In detail, there are numerous possibilities for designing and further developing the wheel according to the invention. Reference is made, on the one hand, to the claims subordinate to claim 1, and on the other hand, to the following description of exemplary embodiments in conjunction with the drawing. The drawing shows

[0026] Figs. 2a, 2b schematically show the wheel according to Fig. 1 with only one first endless spoke connected to a first spoke mounting flange of the hub and with a second endless spoke,

[0027] Figs. 3a, 3b schematically show the wheel according to Fig. 1 with only one third continuous spoke connected to a second spoke mounting flange of the hub and with a fourth continuous spoke,

[0028] Fig. 4a schematically shows a first rim attachment means around which an endless spoke is guided,

[0029] Fig. 4b schematically shows a second rim fastening device to which one

[0030] is guided by an endless spoke and

[0031] Fig. 5 schematically shows a hub with hub attachment means.

[0032] The figures show various aspects of the type of wheel 1 considered here, with a rim 2, a hub 3 and at least one flexible spoke 4 that can essentially only withstand tensile stress.

[0033] Fig. 1 shows a fully assembled and therefore ready-to-use wheel 1. The rim 2 does not carry a tire in any of the figures, but this could easily be provided if the wheel 1 were used, for example, as a wheel of a bicycle or as a wheel for another means of transport.

[0034] The rim 2 has rim attachment points 5 with a receptacle 6 for receiving a spoke 4, and the hub 3 has hub attachment points 7 with a receptacle 8 for receiving a spoke 4. The thirty-two spokes 4 run under tension between each of the hub attachment points 7 and one of the rim attachment points 5, so that the hub 3 is held centrally within the circumference of the rim 2 by the spokes 4. In the figures, the rim attachment points 5 and the hub attachment points 7 are only partially labeled with reference numerals for clarity.

[0035] All embodiments have in common that the spokes 4 are realized by flexible, continuous spokes 9. Embodiments are conceivable in which not all spokes 4 are realized by one or more flexible, continuous spokes; however, these are not shown here. A flexible, continuous spoke 9 is a closed, continuous tensile element; therefore, it has no beginning and no end.

[0036] In the wheel 1 according to Fig. 1, the spokes 4 are formed by several continuous spokes 9, which are otherwise identical in design, such that each of the multiple continuous spokes 9 forms the same number of spokes 4. Specifically, eight spokes 4a, ..., 4a8; 4b1, ..., 4b8; 4c1, ..., 4c8 and 4dl, ..., 4d8 are each realized by one continuous spoke 9a, 9b, 9c and 9d. Each of the continuous spokes 9a, ..., 9d runs between several rim attachment points 5 and hub attachment points 7 and thereby forms a plurality of spokes 4.

[0037] Figures 2a, 2b and 3a, 3b show the wheel 1 from Figure 1 with only partial lacing. Figures 2 and 3 serve to illustrate the course of the endless spokes 9a, ..., 9d between the rim attachment points 5 and the hub attachment points 7.

[0038] The hub 3 has a first spoke mounting flange 10a and a second spoke mounting flange 10b on opposite sides of the wheel plane defined by the rim 2. In the depicted horizontal orientation of the wheel 1, the first spoke mounting flange 10a, which points towards the viewer (see Fig. 2), conceals the second spoke mounting flange 10b, which points away from the viewer (see Fig. 3).

[0039] Fig. 2 shows the path of the continuous spokes 9, which are connected to the upper, first spoke mounting flange 10a and the hub attachment points 7 arranged thereon. Fig. 2a shows only a single flexible continuous spoke 9a, which forms the eight spokes 4al, ..., 4a8. The spokes 4al, ..., 4a8 formed by the continuous spoke 9a, which thus run between a rim attachment point 5 and a hub attachment point 7, are distributed rotationally symmetrically with respect to the wheel center. Fig. 2b shows another continuous spoke 9b, which forms the eight spokes 4b1, ..., 4b8, which are also arranged rotationally symmetrically. It can be seen that all hub attachment means 7, which are arranged on the upper, first spoke mounting flange 10a, have been used for the spoke tensioning; all hub attachment means 7 are connected by spokes

[0040] 4 embraced.

[0041] Figures 3a and 3b show the lower, second spoke mounting flange 10b and consequently the course of the continuous spokes 9c, 9d, which are connected to the lower, second spoke mounting flange 10b and the hub attachment points 7 arranged thereon. Figure 3a shows only a single flexible continuous spoke 9c, which forms the eight spokes 4c1, ..., 4c8. The spokes 4c1, ..., 4c8 formed by the continuous spoke 9c, which thus run between a rim attachment point 5 and a hub attachment point 7, are also arranged rotationally symmetrically with respect to the wheel center. Figure 3b shows another continuous spoke 9d, which forms the eight spokes 4dl, ... ., 4d8 forms, which are also arranged rotationally symmetrically. Together, the coverings in Figs. 2b and 3b constitute the complete covering of the wheel 1 shown in Fig. 1.

[0042] In the wheels 1 shown in the figures, the endless spoke 9 is guided around the receiving structure 6 of the rim attachment 5 and the receiving structure 8 of the hub attachment 7 such that the guidance of the endless spoke 9 around the receiving structure 6 of the rim attachment

[0043] 5 and the receiving structure 8 of the hub connecting element 7 form a force-fit connection between the endless spoke 9 and the respective rim connecting element 5 and the respective hub connecting element 7. In the illustrated embodiment, the force-fit is achieved exclusively under tensile load on the endless spoke 9; there is no clamping of the endless spoke 9. Due to the force-fit at the respective rim connecting element 5 and hub connecting element 7, each spoke 4, i.e., a section of the endless spoke 9 between two connecting elements, can be considered almost separately in terms of force.

[0044] As can be clearly seen in Figures 1 to 3, and especially in Figure 4, the rim fastening element 5 is arranged on the rim 2 such that the receiving structure 6 of the rim fastening element 5 is exposed when the rim 2 is in its operational state. This allows the continuous spoke 9 to be guided around the receiving structure 6 of the rim fastening element 5 for the purpose of mounting the continuous spoke 9. Therefore, it is by no means necessary to disassemble the rim 2, for example, by splitting it, in order to guide the continuous spoke 9 around the rim fastening element 5. In the embodiment shown in Figure 4b, the rim fastening element 5 is positively embedded in the rim 2. In the embodiment shown in Figure 4a, the rim fastening element 5 is formed integrally with the rim 2.

[0045] Figure 5 shows that the hub receiving structures are also

[0046] 8 of the hub 7 are exposed, so that here too, the endless spokes 9 can be mounted and the endless spoke 9 guided around the hub attachment means 7 without prior exposure of the hub attachment means 7.

[0047] As can be clearly seen in Fig. 5, the hub coupling element 7 has a post element 11 as a receiving structure 8, with the post element 11 protruding from the wheel plane defined by the rim 2. In the present case, the hub coupling element 7 has two post elements 11 as receiving structures, with the two post elements 11 protruding from the wheel plane in essentially opposite directions. Each post element 11 has a constricted sleeve on the side that is to be encircled by the continuous spoke 9 for the purpose of securing the position of the continuous spoke 9. The upward-pointing post element 11 is clearly visible, while the downward-pointing post element 11 is concealed by the spoke mounting flange 10 and is only shown in a highly simplified manner for the sake of clarity (for example, the constricted sleeve is not shown).In other embodiments, not shown here, the post elements are not circular cylindrical or sleeve-shaped, but instead have, for example, a teardrop-shaped cross-section, thus tracing the course of the endless spoke over a larger section.

[0048] In the embodiment shown in Fig. 5, the endless spoke partially encircles

[0049] 9. The first post element 11 of the two post elements 11, which project in opposite directions from the wheel plane, is guided over an edge 12 of the hub attachment element 7 and then partially wraps around the second post element 11, resulting in three intensive contact points for achieving frictional engagement. The resulting wrap angle between the continuous spoke 9 and the respective post element 11 is greater than 180°, which is advantageous for achieving high frictional forces. The same principle can also be applied to the rim attachment element 7, as can be seen in Fig. 4a. In both cases (Fig. 4a and Fig. 5), the two post elements 11 are arranged on a flat support structure 14 of the rim attachment means 5 and the hub attachment means 7, wherein the flat support structure 14 is arranged essentially in the wheel plane or parallel to the wheel plane.Here too, the continuous spoke 9 is guided around the post elements such that the realized wrap angle between the continuous spoke 9 and the respective post element 11 is greater than 180°. In the case of Fig. 5, the flat support structure 14 is formed by a spoke mounting flange 10 on the hub, and in the case of Fig. 4, the flat support structure 14 is arranged on the inner circumference of the rim 2 and points towards the hub 2.

[0050] The post elements 11 according to Figs. 4a and 5 are implemented as exposed post elements 11 of the receiving structure 6, 8, meaning they protrude from the receiving structure. In another embodiment, not shown here, the post elements 11 are implemented as internal, protected post elements within the receiving structure. Considering Fig. 5, this could mean, for example, that the spoke mounting flange 10 is designed as a disc with the thickness of the disc shown in Fig. 5 plus the length of the post elements 11 protruding in Fig. 5. The path of the continuous spoke 9 – as shown in Fig. 5 – is then defined by a recess in the thicker spoke mounting flange. The result is also a post element, but it is implemented in the plane of the disc of the spoke mounting flange, i.e., internal and protected within the spoke mounting flange.

[0051] Fig. 4b shows a further variant of the design of a connecting element, using the rim connecting element 5 as an example. This element is designed in a connecting element plane in the wheel plane and has a retaining structure 6 for the endless spoke 9, a suspension structure 15 in which the endless spoke 9 is held in a fixed position under tensile load in the direction of tension. To improve the force transmission, the endless spoke 9 is guided over an edge of the rim connecting element 5. The endless spoke 9 is guided into the first suspension structure 14a from below the connecting element plane, is guided through the first suspension structure 14a to above the connecting element plane, runs above the connecting element plane to the second suspension structure 14b, then runs from above the connecting element plane through the second suspension structure 14b to below the connecting element plane, and from there to the next hub connecting element 7.It goes without saying that the terms "below" and "above" are relative and can be consistently interchanged to achieve the intended guidance of the endless spoke 9. Overall, the rim attachment element 5 in Fig. 4b is flat with constrictions forming a suspension structure 14.

[0052] Fig. 4b further shows that a deflectable clamping device 16 is arranged on the rim attachment point 5, with which the running path of the endless spoke 9 can be influenced, in this case in the area of ​​the rim attachment point 5, so that the tension in the endless spoke 9 can be influenced accordingly. In the exemplary embodiment, the clamping device 16 is wedge-shaped, with the wedge being transversely adjustable by a screw. The wedge shape of the clamping device 16 allows for a first influence on the spoke tension, and the transverse adjustment of the wedge allows for a further influence on the spoke tension. In another (not shown) embodiment, the clamping device 16 is realized on the edge 12 of the rim attachment device 5, and in yet another (not shown) embodiment, the clamping device 16 is realized on the edge 13 of the hub attachment device 7.Although not shown in detail, the distance between the first spoke mounting flange 10a and the second spoke mounting flange 10b, viewed in the axial direction of the hub, is adjustable in the described wheels 1. This is made possible by a linear guide formed between the axis of the hub 2 and the spoke mounting flanges 10a, 10b. The linear guide is designed according to the model of a splined or toothed shaft connection. This measure allows the travel of the endless spokes 9 between the rim attachments and the hub attachments to be changed. As a result, in contrast to the previously described clamping devices 16, which are provided at the attachments 5, 7, the tensile tension in the spokes 4 can be adjusted uniformly and simultaneously.
