Definitions

  • the invention relates to a spoke wheel according to the preamble of claim 1, rims according to the preamble of claim 8, manufacturing method according to the preamble of claim 11, nipples according to the preamble of claim 14 and a frosted spoke wheel according to the preamble of claim 16.
  • spoked wheels that have been in use for decades - hereinafter referred to as "conventional" - all have a spoke-rim connection in such a way that the spokes on their radially outer end (all position information relate to the completely assembled wheel, unless expressly stated otherwise) ) has an external thread which engages in the internal thread of a nipple, which in turn is supported with a collar at its radially outer end against a round rim hole, the diameter of which is only slightly larger than that of the nipple neck and smaller than the collar diameter.
  • this connection technology it is essential that the nipple holes penetrate the rim completely so that the nipples can be inserted into the rim holes from radially outside to radially inside.
  • This mounting direction of the nipples has the disadvantage that when one of the nipples has been overtightened or a spoke at its thread start has been torn off so that the rest of the spokes can no longer be unscrewed from the nipple, only the entire tires, i.e. pneumatic tires, inner tube and rim protection - tape must be removed to replace the nipple and then reapplied.
  • This procedure is very complex, which leads to the fact that the spoke-nipple-rim connection, at least in bicycles, must be designed for everyday use with considerable safety reserves with the associated disadvantages such as reduced wheel deflection in the spoke rim, higher weight and higher air resistance.
  • a spoke wheel is known from the magazine "Motorrad", issue 19, 1987, pages 7 to 14, where the spoke-rim connections are shifted axially outward into the rim flanges. In order not to let the rim flanges get too thick, this connection cannot be set; instead, unchanged nipples allowing the spoke tension are used as the hub-spoke connection. The cross-section of the spokes runs through this spoked wheel, which requires very stiff rims to avoid buckling. In addition, a large hub flange diameter is required so that the nipples attacking there leave enough space for a turning tool. - In contrast to heavy motorcycles, both requirements are generally not met with lighter bikes, especially bicycles.
  • the solutions of the 1st group show keyhole-like nipple holes in the rim, the conventional nipples being inserted radially inwards through an enlarged opening and then being shifted in the circumferential direction into a narrower area of the nipple hole and there, in the side view, due to the spoke cantilever position Find a stable location.
  • the nipples are suspended in the rim in an articulated manner, only a little more than half of the nipple collar being supported by the inner rim flange, which results in load peaks on the rim and nipple.
  • the center of the pressure surface is no longer in the center of the spoke in this solution group, so that the rim initiates a torque in the nipple, which passes it on to the screwed-in spoke.
  • This torque not only complicates the nipple turning required for spoke tensioning, but also increases the risk of breakage in the thread base of the spoke.
  • each wheel has as many additional components as spokes, namely the articulated intermediate links, as a rule 36, compared to the conventional solution.
  • all of these additional components have to be used in a movement that is complicated to coordinate, which is a fully automated large series ⁇ manufacturing hindered.
  • the object of the invention is to provide a spoke-rim connection for a spoke wheel that allows a spoke change without tire removal and is at least free from the mentioned disadvantage of contamination. Compared to the conventional solution, it should preferably not require any additional components and should not impair the strength. Insofar as new components such as nipples or rims are required for the connection technology to be created, their specification is of course part of the task.
  • the essence of the invention is that the previously common connection between the nipple and the rim, which consists of a nipple collar and a smooth rim hole, the nipple collar having a larger outside diameter than the rim holes having an inside diameter, is replaced by a further pair of threads.
  • the solution according to the invention cannot be concluded.
  • the average specialist does not come up with the intermediate step conceivable from the retrospective, namely to remove the adjustability from the spoke-nipple connection and to shift it to the nipple-rim connection, a connection technique in which an external nipple thread interacts with an internal rim thread, which means power transmission and Adjustability is guaranteed, but the connection nipple / spoke is designed so that a collar is compressed on the spoke - similar to the connection at its radially inner end to the hub flange - which collars against the tapering of the nipple hole at its radially inner (installation position in relation to complete joined spoke wheel) supports the end.
  • the second obstacle is overcome even more perfectly by combining it with the further invention not to produce the rim holes at risk of tearing out as previously by punching or drilling, that is to say with loss of material, but rather - at least essentially - by plastic deformation. This results in a thickening in the area of the nipple holes. This leads to a load-oriented course of the metallurgical structure boundaries.
  • the increase in strength achieved by cold working has a particularly strong effect on aluminum rims.
  • the rim-spoke connection according to the invention acts like a conventional one with an increased thread pitch, but increased friction, so that impairment of the self-locking can be avoided.
  • the rim is designed as a hollow rim with an inner and an outer flange, then preferably the nipple holes only penetrate the inner flange, a further disadvantage of the usual rim-nipple-spoke connection is overcome, which is that the inevitable breakthrough of the rim well represents a leak, so that such spoke wheels could only be driven with a hose.
  • the radially outer rim flange is uninterrupted, both a rim tape and a tube can be dispensed with. This reduces the wheel weight and, moreover, it is known from truck and car tires that they have a lower rolling resistance in a tubeless design.
  • the hole or thread axis must be precisely aligned with the spokes on the finished spoked wheel, because the nipples have almost no possibility of automatically adjusting their inclination with respect to the rim.
  • the problem therein that the rim manufacturer may not immediately get the hub manufacturer to commit to a single or possibly a small number of versions of the hub flange can be avoided by inserting an additional joint between the nipple and the rim, as claimed in claim 2.
  • the outer flange of the rim is curved radially outward in its axially central region.
  • Such a curvature of the axially central region of the outer rim flange of a hollow-chamber rim is possible in the preferred uninterrupted design of the outer rim flange, according to which a rim tape covering nipple holes is superfluous.
  • the space thus freed up is used in this development by the rim without the tire assembly and disassembly being made more difficult.
  • the curvature radially outward can be driven particularly far if the spoke wheel is fitted with tubeless tires, because then additional installation space with a tube wall thickness (approx. 0.7 to 1.0 mm) is gained.
  • the moment of inertia and thus rigidity and strength are significantly increased without any appreciable increase in the circumferential length of the sweeping cross section.
  • This can be used to reduce the rim wall thickness or to increase the rigidity and strength of the rim. Regardless of whether the aim is to increase strength and stiffness or to reduce weight, the relationship between weight on the one hand and strength and stiffness on the other hand of the rim is improved.
  • the curvature of the outer flange radially outwards results in a cross section of the hollow chamber which comes closer to a circular cross section than in the case of previously known rims.
  • such rims also show a higher torsional rigidity in relation to the construction weight.
  • This fact can be used for a or a larger spoke crossing in the front view, as a result of which the resistance of the spoke wheel according to the invention to cross-impacts can be improved; So far this has not been possible with light rims, because a spoke crossover in the front view basically results in a torsional buckling for the rim.
  • the curvature of the outer rim flange increases the available setting range for the spoke length.
  • the setting range is the same as or larger than (than) in the currently common connection technology by means of nipples which are inserted into the rim from the radially outside.
  • the curvature of the radially outer rim flange radially outward it is proposed that the tire feet have a substantially axially extending tire seat in a manner known per se ⁇ sit on the rim.
  • the tubeless tires also make it possible to keep each tire seat area of the rim narrower than the associated tire base, because the tire seat areas need to be only slightly wider than the clear width between the cores after tire installation to avoid carcass crushing underneath the tire cores; with a tube, however, the seat surfaces must be so wide that the sensitive tube is not in a sharp S-shaped curve at the transition point between the tire toe and the rim.
  • a further enlargement of the curvature of the radially outer rim flange to the radially outward is possible if each low bed undercuts the adjacent tire seat surface.
  • the axially outer end of a deep bed can lie further axially outwards than the axially inner end of the associated tire seat surface.
  • the central area in which the rim can be curved radially outwards is enlarged by this feature and thus the maximum possible bulge itself.
  • Only the radially outer end of the transition surface between the deep bed and the seat surface should be designed so that it extends radially outwards extended to make it easier for the tire foot to slide onto the seat. It is advisable to make sliding even easier by lubricating drop center and rim seat surfaces, including the surface in between, with a viscous lubricant, such as paraffin or petroleum jelly, before fitting the tire.

  • the spokes (6) have an external thread (7) at the radially outer end and engage in the matching internal nipple thread (4).
  • the outer rim flange 11 is continuous and therefore does not require a rim tape cover. According to a further development, the outer rim flange 11 is curved radially outwards in its axially central region. So far, the rim beds have been arched the other way around to create the necessary space for the tire assembly.
  • the space previously occupied by the rim tape and preferably also by the tube is added to the rim.
  • a certain reduction in the size of the assembly room can be accepted, since the tire toes slide better against the metallic rim than against the previously required sweeping tape made of rubber or textile.
  • Figure 4 shows another variant of the invention, where the nipple holes 2 are arranged in two spaced rows. This results in a greater inclination of the spokes (6) in the front view with the hub flange spacing unchanged. The spokes (6) crossed in this way lead to a higher transverse rigidity and transverse strength of the spoke wheel.
  • FIG. 5 illustrates the buckling provoked in this way:
  • the rim 1 which is subjected to pressure in the circumferential direction, spontaneously buckles to the side and thereby twists.
  • the figure 3a on the left shows the target position and the figure 3b on the right shows the bent position. Due to an increased torsional rigidity of the rim 1, this buckling is shifted to greater compressive stresses of the rim 1 or to a greater distance between the two rows of nipple holes 2. As a result, this feature, which is known per se from heavy rims, can also be applied to light rims 1.
  • FIG. 6 shows a cross section through a spoke wheel according to the invention.
  • nipple holes 2 with an internal thread 9 are arranged, which only penetrate the radially inner rim flange 10.
  • the outer rim flange 11 is continuous and therefore does not require a rim tape cover.

  • the nipples 3 are hollow along their entire length and have a continuous internal thread (4).
  • the tensioned spokes 6 engage with the external thread 7 matching the internal nipple thread (4).
  • Nipple internal thread (4) and external nipple thread 8 differ in their pitch; a deviation only in the amount of the slope, i.e. with the same slope orientation, has the advantage that the nipples can be kept particularly slim because there is a high reduction between the nipple rotation and the spoke span. So small thread diameters are enough to achieve the necessary self-locking. Furthermore, the spokes can be adjusted very precisely. In contrast, a deviation between the inner (4) and.-Outer thread 8 in the orientation has the advantage that the spokes 6 can be tightened quickly with a few nipple rotations. However, the diameter of the external nipple thread - and thus of course the internal thread of the rim - must be increased in order to build up a sufficient friction torque to prevent the spoke from turning automatically.
  • the nipples 3 have a torque introduction point, in this case a square 5, in a manner known per se.
  • the tool for setting the spoke tension should act.
  • the peculiarity in this figure lies in the fact that the radially outer rim flange 11 is curved radially outward in its axially central region and that there is a deep rim bed 16 to the left and right of it, so that tire mounting on known, essentially axial extending tire seating surfaces 15 is possible.
  • the tire seat surfaces 15 are straight with an inclination to the axial of 10 °.
  • the transition surface 19 is inclined so that the axially outer edge 16.1 of each deep bed 16 lies further axially outward than the axially inner edge 15.1 of the associated tire seat surface 15, that is to say the seat surfaces 15 are partially undercut , but the tire seat surfaces 15 are also kept narrower than the tire feet 17.

  • the dimension 15.2 between the axially inner boundaries 15.1 of the tire seat surfaces 15 is 2 to 12%, here 9%, smaller than the dimension 18.2 between the axially inner boundaries 18.1 of the bead cores 18 in the fully assembled on the rim 1 Status.

  • the curvature of the outer rim flange 11 radially outwards leads to the increases in bending rigidity, torsional rigidity and bending strength mentioned.
  • this design leads to a large spoke length tolerance dimension 6.1, which is to be measured from the radially outer end of the internal rim thread 9 to the inner contour of the outer rim flange 11 along the spoke screwing direction.
