No. 08/893,700, filed Jul. 11, 1997, in the names of Jean-Pierre Mercat and Alban Minville, entitled “METHOD FOR BORING A SPOKE RIM, RIM BORED ACCORDING TO THE METHOD, INSERT ADAPTED TO EQUIP THE RIM, AND WHEEL ESPECIALLY CYCLE WHEEL”, now abandoned.
- 1. Field of the Invention
- The present invention relates to a method for boring a wheel spoke rim. The invention also relates to a rim obtained using the method. The invention is also related to a spoke, a spoke nipple provided to equip the rim obtained by the method, as well as a wheel obtained by assembling the rim with such spokes and spoke nipples.
- 2. Background and Material Information
- In a known manner, a wheel, especially a bicycle wheel, includes a central hub connected to a circular rim by two rows of spokes. The rim is formed of two circular bridges connected by two lateral flanks so as to form a box. The lateral flanks are extended outwardly by two wings, so as to form, with the upper bridge, an annular channel provided to receive a tubular. For certain rims that are provided to receive a tube, the channel is a mere groove formed by a caving-in of the upper bridge. The spokes are connected to the rim by nipples screwed at the end of the spokes. These nipples further make it possible to adjust the tension of the spokes.
- To receive the spoke nipples in a conventional manner, the two bridges of the rim are bored with openings spread along the circumference of the rim. The openings of the lower bridge are provided to serve as a seat for the nipple heads. The openings of the upper bridge, with a greater diameter, are provided to enable the positioning of the spoke nipple from the outside.
- To improve the conditions in which the nipple head takes support against the rim, and the distribution, in the rim, of the stresses induced by the tension of the spokes, it is known to equip the rims with eyelets that extend through the openings of the lower bridge. These eyelets are assembled by crimping to the periphery of the opening of the lower bridge. They further have a cup-shaped eyelet body whose lower portion rests on the lower bridge, and the upper portion has an edge that rests against the upper bridge. The base of these eyelets is bored for the passage of the nipple body. These eyelets are advantageous because they establish mechanical linkages between the two bridges, which reinforces the structure of the rim and its bending strength.
- A monoblock eyelet is described in the patent application EP 130 449. These eyelets also exist in the form of two distinct elements assembled at the level of the crimping.
- However, for such rims, the openings of the bridges constitute local weakening zones which weaken each of the two bridges. In addition, these openings must have a relatively large size. The openings of the lower bridge must indeed have a diameter that is sufficient to allow for the passage of the nipple body and its free rotation. The openings of the upper bridge must enable the passage of the nipple head upon which the fastening of the spoke to the rim, as well as the adjustment tools are dependent.
- Another problem of these rims is that when adjusting the tension of the spokes, the spoke itself is torsionally biased and twists over itself before a relative movement occurs at the level of the threads for linking with the nipple. As a result, the tension adjustment of the spokes is relatively inaccurate, and the spokes do not work properly.
- Another problem of these rims comes from the manufacturing of the eyelets. Indeed, if one wishes to equip the rim with cup-shaped double eyelets, the distance between the two bridges of the rim is directly related to the height of the cup of the eyelet. Since the eyelet is conventionally made of stainless steel by stamping, the maximum height of an eyelet is thereby limited, which imposes dimensional constraints for the rim.
- However, a rim having threaded openings is known from the published Patent Application No. WO 93/09963. The threaded end of the spokes is connected to this rim by means of a nipple that is threaded internally and externally with a different pitch. This rim further has an unpunched upper bridge, except for the mounting of a valve, if necessary, which makes the rim airtight, and therefore appropriate for the mounting of a tubeless type of tire.
- However, the lower bridge that is bored and threaded must be reinforced in its thickness to withstand the stresses, which results in an undesired increase in the weight and inertia of the rim. The mode for mounting the spokes does not solve the spoke twisting problem either.
- An object of the invention is to propose a method for boring a rim which makes it possible to obtain a rim having improved mechanical characteristics, without any significant weight increase.
- Another object of the invention is to propose a rim bored with openings which has an improved resistance to fracture.
- Another object of the invention is to propose a rim in which the distance between the two bridges is freed from the height limit constraint for the cups of the eyelets.
- Another object of the invention is to propose a wheel equipped with spokes whose tractional working conditions are improved.
- Other objects and advantages of the invention will become apparent along the description that follows.
- According to the invention, the method for making a rim bored with openings provided to receive spokes for linkage with a hub, the rim having a box with an upper bridge and a lower bridge, includes the feature that at least the lower bridge is bored with a through hole by means of flow drilling bit operating in the direction of the upper bridge.
- The rim obtained using the method includes the feature that at least one of the bridges has a plurality of through holes demarcated by a backflow chimney whose height is greater than the thickness of the bridge.
- The spoke provided to equip the preceding rim includes the feature that it has a joining piece affixedly assembled to the end of the spoke, and a tension adjusting screw mounted to rotate freely and set back with respect to the joining piece.
- The wheel according to the invention has a rim such as aforementioned, a central hub and connecting spokes between the rim and the hub.
- According to another characteristic, the rim includes at least one spoke such as aforementioned.
- The invention will be better understood along the following description, with reference to the annexed drawings that are an integral part thereof, and in which:
- FIG. 1 a general side view of a wheel;
- FIG. 2 is a front view of the wheel of FIG. 1;
- FIG. 3 is a partial front and cross sectional view, through a transverse plane of section, of a rim in the raw state;
- FIG. 4 illustrates the operation of boring the rim according to a first embodiment of the invention;
- FIG. 5 shows the result of the boring operation;
- FIG. 6 illustrates the following step of threading the openings of the rim;
- FIG. 7 shows a front and cross sectional view, through a transverse plane, of an insert provided to be screwed in the openings;
- FIG. 8 is a top and cross sectional view of the insert of FIG. 7;
- FIG. 9 shows the insert mounted in the rim;
- FIG. 10 is a side view of a spoke provided to be assembled to the insert;
- FIG. 11 is a view similar to FIG. 10 where the elements located at the end of the spoke are shown in cross section;
- FIG. 12 shows the spoke assembled to the rim;
- FIG. 13 is a view similar to FIG. 12 and illustrates another embodiment of the invention.
- FIG. 1 shows a bicycle wheel which includes a
circular rim 2 connected to acentral hub 3 by spokes 4. Only a portion of the spokes is shown in this FIG. In a known manner, the hub has appropriate means for providing the linkage with the frame. As is visible in FIG. 2, the spokes are distributed along two symmetrical rows, each of which is fastened to an end of thehub 3. - The wheel shown in FIGS. 1 and 2 is a front wheel. In the case of a conventional rear wheel, one of the rows of spokes is offset toward the median portion of the hub, such that the hub has, on this side, a joining piece that includes the free wheel mechanism and serves as a support for the sprocket box. This is known to one with ordinary skills in the art.
- FIG. 3, in a transverse cross section and partial view, shows the
rim 2 in the raw state. This rim has, in a known manner, a box structure having alower bridge 5 and an upper bridge 6 connected bylateral walls wings 9 and 10 which form, with the bridge 6, an annular channel provided to receive a tire and a tube, if necessary. - The rim shown in the FIG. is however not limiting for the invention, neither with respect to the profile of the section, nor with respect to the mounting of a tire. The invention indeed applies to rims provided to be equipped with a tire as well as to rims provided to be equipped with a tube or any other tire tread.
- In a known manner, the rim such as that shown in FIG. 3 is obtained from a shaped bar made of aluminum alloy or of any other light alloy, such bar being bent and then butt joined by means of a sleeve or by welding. In the raw state, the two bridges are unpunched continuous walls.
- FIGS. 4 and 5 illustrate the operation of boring the rim. This operation, in a known manner, consists of boring the two bridges of the rim at regular intervals, in order to enable the fastening of the spokes. It must be noted that the boring of the openings takes into account the specific orientation of each spoke, such orientation being determined by the general orientation of each row, and by the number of spokes per row.
- According to the invention, the rims are bored, not by means of a conventional cutting drill, but by means of flow drilling drill bit. The flow drilling technique is known in itself. The drill bits used for such a boring have a generally cylindrical shape, with a punch-shaped tip. The tip is formed with edges, which gives it a general shape of pointed pyramid. Other tool shapes are also suitable.
- Two
tools - The flow drilling technique has the particularity of not cutting the material, but rather of pushing it in the direction of progression of the drill bit along a chimney. In the present case, the chimneys are oriented toward the interior of the box of the rim.
- Flow drilling can create a burr on the side opposite the chimney. This burr is trimmed off or shaped by the drilling tool itself which has at least on trimming tooth for this purpose. The burr can also be trimmed off or shaped by a proper machining operation.
- FIG. 5 shows the rim in transverse cross section at the level of a pair of openings, after drilling and removal of the drill bits. Each
bridge 5, 6, has a throughhole chimney openings - For each chimney, the height of the wall, and its thickness depend on the characteristics of the material of the rim, on the initial thickness of the bridge, on the diameter of the drill bit, and on drilling parameters, rotational speed, progression speed, etc.
- One was able to obtain the following results.
- For a rim made of aluminum alloy6106, a 1.5 mm bridge was bored with a drill bit having a 5.5 mm diameter. The chimney obtained had a useful length of about 5 mm, this length including the thickness of the bridge.
- It must be noted here that the boring of the openings using the flow drilling technique is advantageous with respect to the mechanical strength of the rim. Indeed, the structure of the material does no longer have any sudden discontinuity as is the case for a conventional boring by cutting. Due to its peripheral wall, the chimney maintains a certain homogeneity in the structure of the bridges, such that the mechanical resistance to fracture of the rim thus bored is higher than that of a rim bored in a conventional manner.
- Another advantage is that such a flow drilling does not generate any chips; in particular, there is no chip that could penetrate into the box.
- Finally, the two chimneys are oriented toward the interior of the box; therefore, there is no portion projecting outwardly, especially on the side provided for the tire or the tube.
- FIG. 6 illustrates the next manufacturing step which consist of threading the two
openings - The
insert 18 provided to be screwed in the two threaded openings is shown in FIGS. 7 and 8. It has the shape of a tube portion that is threaded at its outer wall with respect to the diameter and pitch of theopenings lower bridge 5, such that once screwed in the two openings of the bridges, the insert is totally integrated within the perimeter of a section of the rim. - The interior of the insert is also threaded to a pitch that is independent of the external pitch of the insert. In addition, the interior of the insert has, at least in its lower portion, a polygonal section, for example hexagonal, that is obtained in the thickness of the threading. Initially, this hexagonal section makes it possible to screw the insert in the
openings insert 18 in a top view, with itsbody 19, on the exterior of the body, athread 20 of the external threading, and on the interior of the body, aninternal thread 21 sectioned by sixtriangular grooves 22 that are distributed at the peaks of a hexagon, and together define a hexagonal section. - Other means can also be suited to ensure the coupling with a tool in order to carry out the screwing of the insert, for example, one or more grooves provided in the inner wall of the insert along all or part of its height, and provided to cooperate with a tool carrying one or more lugs arranged appropriately.
- Likewise, the insert could have on the side of the lower bridge, i.e., toward the interior of the rim, a projecting extension, with a hexagonal external section, for example, which enables the coupling of a screwing tool. This replaces the hexagonal section within the insert. This internal hexagonal section is however preferred, because it enables a weight gain on the inserts, as well as a saving in space, and it facilitates the spoke positioning which will be described in detail subsequently.
- The insert is made of any appropriate material, such as aluminum alloy, for example.
- The insert is provided to be screwed in the
openings - Advantageously, the
insert 18 provides a mechanical linkage between the twobridges 5 and 6, which operates both ways in a longitudinal direction defined by the insert. That is, contrary to the eyelets that are crimped on one of the bridges and in mere support on the other, the inserts here are embedded in each of the bridges, and they connect the bridges affixedly. The risk of the box collapsing is considerably reduced. The structure of the rim is stiffened by such linkages. It was already stiffened by the backflow chimneys. In addition, the flow drilling makes it possible to have, at the level of each bridge, a threading height that is much greater than the initial thickness of the wall of the bridge. In other words, a screwing linkage can be used here without significantly increasing the thickness of the wall. Furthermore, the length of the insert is not limited by manufacturing constraints, such that the distance which separates the two bridges of the rim is selected without any constraint relative to the length of the insert. The shape of the lower bridge can also be selectively more streamlined, for example, because the insert is no longer crimped but screwed within the rim. - A spoke provided to be fastened to the rim by screwing in the insert is shown in FIGS. 10 and 11.
- The
spoke 25 shown is a wire with abent head 26 that is provided to be hooked to a lateral flange of a hub, by force fitting in one of the openings of the flange. Of course, this is not limiting, and the spoke could also have a strait head, i.e., with no bend, and could be assembled by any technique other than force fitting, for example, by a mere engagement of the head in a buttonhole-shaped housing, or in a cutout. The median portion of the spoke has any section, in particular, it can be cylindrical or have an aerodynamic profile. The spokes could also be replaced by sticks assembled to the hub or integral therewith, the portion of the spokes which will now be described constituting the end portion of such sticks. - The spokes could also be formed from composite fibers.
- This end portion includes a joining
piece 28 that is affixed to the end of the spoke by any appropriate means, for example, screwing or adhesion on the threaded end of the spoke. The tip could also be assembled by welding, by caulking the end of the spoke, or it could be obtained by die forging the end of the same spoke. According to the mode of assembling the head of the spoke to the hub, especially by force fitting or by engagement into a slit, the joining piece is assembled after or prior to the operation of positioning the spoke on the hub. - The joining
piece 28 has a polygonal section, for example hexagonal, which corresponds to the internal section of the insert. The joining piece is provided to engage and slide within theinsert 18. The fact that the insert has an internal hexagonal section facilitates the positioning of the spoke, even before its tightening. - The cooperation between the hexagonal sections of the joining piece of the spoke and of the insert has the effect of retaining the end of the spoke in rotation, i.e., this prevents any twisting of the spoke. As has been said previously regarding the hexagonal section of the insert, any other appropriate means performing this function is suited.
- At the rear of the joining piece, the end of the spoke carries a
tension adjusting screw 30 which is traversed by the spoke and is mounted to rotate freely at its end. The screw is provided to abut against the joiningpiece 28 and to exert thereon a thrust that induces a tension in the spoke by reaction. Thescrew 30 is also provided to be tightened within theinsert 18, thereby inducing a translation of the joiningpiece 28 within the insert. - Preferably, as is shown in FIGS. 10 and 11, the tension adjusting screw is extended on the side opposite the joining piece by a coupling sleeve with the tightening tool, such a
sleeve 31 having a hexagonal section, for example. Any other appropriate means is also suitable. - FIG. 12 schematically shows the rim in a plane of section including the insert.
- This FIG. shows the various elements, in particular the
insert 18 engaged in the two openings of thebridges 5 and 6 of the rim, the joiningpiece 28 slidably engaged in the insert, and thetension adjusting screw 30 partially screwed in the insert, with thecoupling sleeve 31 accessible on the outside of the rim and which makes it possible to adjust the tension of the spoke. It must be noted that when adjusting the tension, the spoke only works in stretching since the joiningpiece 28 prevents the end of the spoke from pivoting. The spokes work in better conditions and the tension adjustment is thereby more accurate. - The construction that has just been described can be carried out with numerous variations. For the linkage between the rim and the insert, it would be possible, for example, to use a drill bit which provides the threading of at least one of the openings during the same operation. One could also use self-threading inserts, i.e., which create their own threading when they are screwed. Another variation would consists of threading only one opening, for example the opening of the lower bridge, and of ensuring the linkage with the other bridge by means of a self-threading section of the insert. According to another variation, the two openings could be bored by a single oriented drill bit operating on the upper bridge, and then on the lower bridge. Such a boring would have the effect of orienting the chimney of the lower bridge toward the outside of the box. According to another variation, the two openings could have different diameters, the insert having in this case a shoulder on which it can rest to ensure its tightening in the openings. One could also use a blind insert on the side of the upper bridge.
- In this regard, FIG. 13 shows another embodiment of the invention. According to this embodiment, only the
lower bridge 35 of therim 32 is bored according to the flow drilling technique, so as to create achimney 37. Theupper bridge 36 is not bored, it remains in the raw state. As is in the preceding case, aninsert 38 is engaged by screwing in thechimney 37, and is tightened against the upper bridge. Theinsert 38, as theinsert 18, has an internal wall threaded and machined along a hexagonal section. - The
spoke 39 provided to cooperate with theinsert 38 is quite similar to the preceding spoke, having at its end a joiningpiece 40 with a hexagonal section, atension adjusting screw 41 extended by a coupling sleeve with a tightening tool. - Such a construction has the advantage that the rim is impervious, i.e., on the side of the tire, it has a continuous bridge that is unpunched, except for the mounting of the valve, if necessary. Such a rim is appropriate for the mounting of a tubeless type of tire, or a mounting where only a portion of the volume defined by the tire is occupied by a tube or a filling material, the other portion being occupied by pressurized air injected between the rim and the tire.
- This other embodiment of the invention can also have alternatives of the same type as those that have been described previously.
- Although the invention has been described with reference to particular means, materials, and embodiments, it is to be understood that the invention is not limited to the particulars expressly disclosed, but that the invention extends to all equivalents within the scope of the claims that follow.
- This application is based upon French Patent Application No. 96 09047, filed on Jul. 12, 1996, the disclosure of which is hereby expressly incorporated by reference thereto in its entirety and the priority of which is claimed under 35 USC 119.
