- the legs of the rider extend through the slots of the rim radially inwardly, the ends of said legs forming tabs folded against the inner wall of the rim.
- the rider is crimped in slots respectively common to the two adjacent riders circumferentially.
- each rider is crimped by means of at least four tabs in at least four slots of the rim, more preferably, through at least six tabs in at least six slots of the rim. rim.
- the support elements comprise a stack of flexible blades and layers of a polymeric composition.
- the support elements have a closed ovoid shape.

- the bandage profile delimits a toroidal internal cavity of ovoid section.
- the tire 1 comprises a fastening zone 5, two sidewalls 12 and a tread 4.
- the fastening zone is intended to be rigidly connected to the wheel hub via a mechanical element such as a disk or wheel sail. (not shown here)
- the tread 4 comprises several circumferential ribs, but this aspect of course has no limiting character.
- the flanks 12 are rounded and occupy most of the radial height of the bandage 1.
- the supporting structure comprises a plurality of support elements 2.
- the support elements are circumferentially adjacent and each extends substantially radially outwardly from the attachment zone 5.
- FIG. 1 also shows a principle of this type non-pneumatic tire according to which it is the bending of the support elements that makes it possible to carry the load.
- the bandage comprises a hundred support element 2. This number can of course be very different depending, for example, on the type of vehicle and the type of use for which it is intended and the characteristics of the support elements. . The number of elements can thus vary for example from 30 to 300.
- FIG. 2 shows a first preferred embodiment of the invention.
- the support elements 2 comprise a stack of blades 21 of composite material, flexible, radially superimposed with interposition between the blades 21 of a layer 22 of polymer or a polymeric composition, especially diene elastomer or polyurethane.
- the bond between the composite material and said polymer being obtained in a known manner, in particular during the baking operation, polymerization or final crosslinking of the assembly, if necessary using an adhesive composition adapted to the nature of the polymer for example as described in WO 04/058909.
- a mechanical preparation (for example by sanding) and / or chemical (for example by the use of an acidic agent) of the surface of the blades can be advantageous for improving the bond between the blades 21 and the intermediate layers 22 .
- each flexible blade 21 is closed, ie it extends all around the bandage section and is not interrupted.
- the stack shown here comprises five blades. This aspect of the constitution of the laminate is however not limiting.
- an interconnection structure 3 disposed radially under the tread 4 connects circumferentially all of the support elements.
- the interconnection structure 3 is relatively rigid in longitudinal tension-compression.
- the composite material of the blades 21 comprises reinforcing fibers embedded in a resin.
- a thermosetting resin matrix is preferably used, but in some less demanding applications a thermoplastic resin may be suitable.
- the fibers are preferably arranged mainly longitudinally in each blade. For example, glass fibers are used. Of course, many other fibers could be used, such as carbon fibers. One could also use a hybrid prepared with fibers of different natures.
- fixing zone is used to designate in general the portion 5 of the tire intended to cooperate with a rigid mechanical part which is otherwise integral with the hub.
- Figure 2 shows an embodiment of the invention whose profile is particularly suitable for the equipment of a 4-wheeled passenger vehicle.
- the support members 2 are closed.

- the fastening zone 5 is embedded (that is to say rigidly bound) on an annular rim 6.
- the fastening zone is axially centered with respect to the tire (see the position of the tire).
- jumper 7 with respect to the median plane 8 of the bandage).
- the bandage comprises a large number of such support elements 2 as is clearly visible in FIG.
- Each support member 2 rests on the periphery of the rim 6 and is connected to the rim via a jumper 7.
- the rider is fixed both radially, axially and circumferentially opposite the rim.
- the attachment is made by crimping (alternatively, the attachment could be made by welding).
- the crimping operation consists of folding the ends of the tongues 10 of the legs 9 of the rider against the inner wall 1 1 of the rim.
- the ends of the legs are in fact foldable tongues (this aspect is however better visible in Figures 5 to 7).
- the riders 7 (as numerous as the support elements 2) are then juxtaposed to each other along the circumference of the rim.
- the number of support elements (and therefore the number of jumpers) is such that the riders bear circumferentially on each other (this preferred aspect is best seen in Figures 4 and 5).
- a main function of the rim 6 is to join together the support elements at their attachment area.
- the rim can then be attached directly or indirectly to the wheel hub (not shown).
- FIG. 3 shows another embodiment of a flexible tire wheel according to the invention.
- the profile of the bandage 1 is adapted to its use for a two-wheeled vehicle such as a motorcycle or scooter.
- the main elements constituting the bandage are identical or similar to those of FIG. 2.
- the support elements 2 here comprise four blades 21 made of composite material and three intermediate layers 22.
- the annular rim 6 is also reduced compared to that of the FIG. 2.
- This rim is intended to be connected to the wheel hub via a rigid element such as a wheel web 25 and not directly as is possible with the rim of FIG. 25 (shown only in part) is intended to fix the rotating assembly on a hub (not shown) of the vehicle.
- the sail comprises fixing means adapted to cooperate with the rim.
- the rim is clamped between a fixed jaw 26 and a removable jaw 27 of the web 25.
- the removable jaw 27 can be held in place by any fastening means such as rivets or screws 28.
- the fixed jaws 26 and removable 27 are preferably circular and monobloc although they may also consist of a plurality of arcs, spaces being left or not between the arches.
- Figures 4 and 5 show the juxtaposition of the support elements 2 on the rim 6. For clarity of the drawings, there is shown only a portion of the annular rim and three support elements held on the rim by their three riders .
- Figure 4 shows the attachment zone 5 from the inside of the tire seen in a radial direction.
- the section plane BB corresponding to the view of Figure 2
- the section plane CC corresponding to the view of Figure 3.
- Figure 5 shows the same sectional attachment area in a plane (AA in Figures 2 to 4) parallel to the median plane of the bandage.
- the upper part of the riders comprises a central zone 71 intended to exert pressure at the center of the stack of flexible blades 21 and rounded folding zones 72 not exerting direct pressure on the stack.
- the folding zones 72 may receive a filling 73, for example consisting of the same composition as the intermediate layers 22.
- the jumper is preferably made of a cut sheet metal, preferably steel.
- FIG 6 shows a jumper before crimping.
- Figure 7 shows the same jumper after crimping. This example corresponds to that of the previous figures.
- Each leg 9 of the rider has a notch 74 defining here two tabs 10 per leg (ie four tabs per rider).
- Each tongue is intended to be folded substantially at 90 ° during crimping.
- the indentation contributes to the axial retention of the rider on the rim and can also be used to introduce the polymer 22 between the flexible blades 21 (by injection, transfer, casting or other method known per se).
- the ends of the tabs can preferably beveled as shown here (see bevels 75) to facilitate their insertion into the slots of the rim.
- the length of the slots can then be adjusted to the width of the tabs to make positioning and lateral support of the rider more precise without increasing the difficulty of mounting.
- each leg 9 of the rider 7 has four tabs 10 inserted into a corresponding number of slots 1 3 of the rim 6. The tabs are separated by three notches 74 similar to that of the previous figures.
- Figure 9 The configuration of Figure 9 is similar to that of Figure 8 except that the side notches 76 have a length limited to the minimum necessary for fixing by crimping.
- the central notch 74 is identical to those of the previous figures.
- the rider has three tabs 10 per leg, the central tongue being here wider than the other two.
- the two indentations 74 are long.
- An advantage of increasing the number of tongues is that, for a given mechanical stress of the jumper-rim connection, the maximum local stresses are reduced. This is particularly true for the local stresses experienced by the rim due to the winding forces which tend to bend circumferentially the support elements relative to the rim.
- the rider may have only one tongue per leg, that is to say do not include indentation, an advantage of this configuration being its great simplicity.
- the two legs of a jumper are identical or similar since they are preferably intended to cooperate with slots common to the adjacent rider within the bandage. However, if the slots are not shared by two jumpers (for example because the jumpers are distant from each other), the two legs of the jumpers may be different, both in terms of the number of tabs and the length of the (or indentations.
- Figures 12 to 14 illustrate the principle of the crimping method of the riders on an annular rim.
- the rim 6 already has a support member 2 'crimped by a rider 7'.
- a new support element 2 and its rider 7 are placed radially.
- the slot 13 ' which has already received the tongue 10' of the first rider 7 'then receives the tongue 10 (not yet folded) of the second rider 7.
- the rider 7 is crimped in turn on the rim 6.
- the crimping is done in a single movement (radial towards the outside) of a punch 81.
- a counter-punch 82 can temporarily hold the jumper in place and even act against the movement of the punch 81 to place the stack of flexible blades under pressure.
- the crimping can also be performed in two successive steps as shown in Figure 14.
- a clamp 83 acting in the circumferential direction of the bandage initially folds partially the tabs 10 before a finishing punch 84 comes to complete the crimping radial.
- Crimping can occur simultaneously on all the tabs of a rider or on a portion of them only (for example one by one or two by two). It is also possible to crimp several riders at the same time with the aid of adapted tools.
- the attachment can be further reinforced by welding, for example by points, tabs folded against the inner surface 1 1 of the rim.
- the attachment of the riders to the rim could be achieved only by welding, without prior crimping.
- An attachment made only by crimping has in particular the advantage of not imposing significant thermal stresses.
- the jumpers can be placed astride the support elements at the time of assembly of the bandage, that is to say immediately before crimping.
- the jumpers may also be placed during a pre-assembly operation, for example during molding of the support members.
- a preferred method for manufacturing a support member and for assembling with a rider comprises successively the following steps:
- the solidification may be obtained in known manner, for example by baking, cooling, crosslinking, polymerization.
- Figure 1 5 uses an outer disc 61 and an inner disc 62 whose peripheries are crimped (and / or welded) on the edges of the annular rim 6.
- the two discs can also be made directly integral for example by welding.
- Figure 1 6 uses a rim in two parts 6a and 6b symmetrical. Each jumper 7 is here crimped into respective slots of the two parts 6a and 6b.
- the two parts 6a and 6b can be made integral (for example by welding or crimping not shown).
- Figures 1 7 and 18 correspond respectively to Figures 1 5 and 1 6 and show more fully the assembly of the flexible tire wheel of the invention.
- the radially outer surface of the rim 6 according to the invention preferably constitutes a bearing surface for the support elements. This function is illustrated for example in FIGS. 2 to 5. Reference can be made to the description of the patent application WO 00/037269 and in particular to FIGS. 9 regarding the possibilities of dimensional variations of these bearing surfaces. It also includes the role of the rim profile and in particular its edges vis-à-vis the distribution of stresses in the support elements as a function of the load carried by the bandage.
- the fixing area is located, preferably on a fraction corresponding to at most 50% of the distance axially separating the lateral limits of the bandage. Said radially inner portion of the supporting structure is thus cantilevered enough pronounced beyond the fixing area.
- a favorable constructive arrangement is that the support elements are, just beyond the fixing zone, oriented in a direction substantially parallel to the axis of rotation of the bandage. This is shown in the examples described here. Note finally that, the bandages described being symmetrical, the fixing zone is substantially centered between the axial limits of the bandages, without this being limiting.
- the support elements can also be open, ie interrupted, for example, as shown in FIGS. 8 and 9 of the patent application WO 00/037269 and in FIG. Patent application EP 1 359 028.
- the closure is provided by the jumper and the attachment means described above as well as, where appropriate, by the bonding polymer to the rider.
- the profile of the annular rim can take different forms, particularly depending on its mode of connection, direct or indirect with the hub.
- the rim can for example be obtained by stamping sheet metal or by spinning.
- the rim is preferably made of steel.
- the slots intended to receive the tabs of the riders can in particular be obtained by machining, stamping or cutting (laser, water jet).
