Definitions
- the present invention relates to a rolling assembly formed mainly of a tire, a rim and an adapter between the rim and the tire.
- a tire commonly used nowadays mainly comprises a tread intended to ensure contact with the ground, this band being generally reinforced by a crown reinforcement which is arranged radially inside the tread.
- the crown reinforcement makes it possible to confer at the top the rigidities, in the three dimensions, necessary for the rolling of the tire.
- the crown reinforcement also limits the radial expansion of a carcass reinforcement, generally composed of one or more plies of radial reinforcing elements.
- a carcass reinforcement generally composed of one or more plies of radial reinforcing elements.
- the carcass reinforcement When the tire is mounted so that it can become functional, it contains an inflation gas inflated to a nominal pressure.
- the carcass reinforcement during the use of the tire reasonable limits, deforms in static and rolling.
- the carcass reinforcement is generally anchored in each bead to a reinforcing ring.
- the beads provide contact with the seat and flange of the tire mounting rim.
- Patent FR 1 267 264 which seeks to confer on a tire the antagonistic properties of comfort, handling, low rolling resistance and high wear resistance, teaches a rough solution, providing the carcass reinforcement with a structure effectively opposing transverse flexibility without impairing radial structural flexibility.
- This structure is obtained by superposition, in the carcass reinforcement, the initial structure of radial reinforcing elements of a secondary structure of inextensible circumferential reinforcing elements.
- This secondary structure may, moreover, modify the shape of the sidewalls of the tire, a shape conferred by the meridian equilibrium profile of the mean axis of the carcass reinforcement: circumferential and inextensible reinforcing elements of substantially equal or lesser diameter.
- this reinforcement at the diameter of the rim flange, and arranged radially and axially inside the radial elements of the carcass reinforcement allow this reinforcement to have a meridian profile that tangents almost horizontally the annular anchoring element of the carcass reinforcement.
- the reinforcing armature for stabilizing the secondary structure has, in the circumferential direction a very large extension stiffness and significantly lower compression stiffness.
- the difference in the modules of the reinforcing reinforcement according to whether one is working in extension or in compression in the radial direction makes it possible to note a significant ovality of the lower external part when such a tire is subjected to a vertical load.
- a transverse force is applied to such an axially loaded tire, a non-linear response of the tire is observed, depending on whether or not the force applied has been sufficient to re-tension the compression part when the tire is loaded. roundness.
- No. 6,626,217 proposes to dissociate in the tire above, the part that can be considered as actually working as a tire of the part that can be considered as working like a rim.
- the corresponding roller assembly consists of a tire, a narrow rim whose width is at most equal to 50% of the maximum axial width of the tire inflated to its operating pressure, and two adapters ensuring the junction between the tire. mounting rim and the beads of the tire, the adapters being made of rubber compositions reinforced and elastically deformable at least in both radial and axial directions.
- the application WO 92/01576 discloses a tire assembly comprising a tire mounted on a rim.
- a removable protector consisting of a circular ring of reinforced rubber is inserted between the bead of the tire and the rim. This protector and intended to protect the bead of the tire against the phenomenon of heating during driving.
- the application FR 2,491,836 describes an adapter disposed between the rim and each bead of a tire intended to facilitate assembly / disassembly.
- One of the objectives of the present invention is to define a rolling assembly having a good guiding capacity while being resistant to sidewalk impacts.

- the rolling assembly comprises two adapters which provide the junction between the mounting rim and the two beads of the tire, but it may also comprise only one adapter.
- Each adapter is preferably "elastically deformable in both directions, radial and axial", in the sense that it allows in the radial direction a clearance between the bead of the tire and the mounting rim of at least 5% of the deflection of the pneumatic tire crushed at the recommended load and pressure, and in the axial direction a reconciliation of the bead of the mounting rim with a value at least equal to 15 mm at zero pressure, these deformations being canceled if the constraints are eliminated; or forces that cause it.
- the radial deformation must be able to intervene during the use of the inflated tire at nominal pressure, while the axial deformation is not desirable in normal operation of the inflated tire at nominal pressure.
- the adapter bead can still be called “axially inner end”.
- the adapter bead is intended to hang the adapter on the rim hook top of a rim, all this is conventionally done by the bead of a tire.
- the housing of the adapter for receiving the bead of the tire, and comprising a housing reinforcement may also be called “axially outer end”. This housing receives the tire bead just as conventionally does the rim hook top of a rim.

- the term refers to a radius of the tire. It is in this sense that a point P1 is said to be “radially interior” at a point P2 (or “radially inside” of the point P2) if it is closer to the axis rotation of the tire as the point P2.
- a point P3 is said to be “radially external to” a point P4 (or “radially outside” of the point P4) if it is farther from the axis of rotation of the tire than the point P4.
- a wire or an armature is said to be "radial (e)" when the wire or reinforcing elements of the reinforcement make with the circumferential direction an angle greater than or equal to 80 ° and less than or equal to 90 °.
- the term "wire” is to be understood in a very general sense and includes threads in the form of monofilaments, multifilament, cable, twisted or equivalent assembly, and this regardless of the material constituting the wire or the surface treatment to promote its connection with the rubber.
- radial section or “radial section” here means a section or section along a plane which contains the axis of rotation of the tire.
- An “axial” direction is a direction parallel to the axis of rotation of the tire.
- a point P5 is said to be “axially inner” at a point P6 (or “axially inside” of the point P6) if it is closer to the median plane of the tire than the point P6.
- a point P7 is said to be “axially outside at” a point P8 (or “axially outside” of the point P8) if it is farther from the median plane of the tire than the point P8.
- the “median plane” of the tire is the plane which is perpendicular to the axis of rotation of the tire and which is equidistant from the annular reinforcing structures of each bead.
- a “circumferential” direction is a direction that is perpendicular to both a radius of the tire and the axial direction.
- rubber composition refers to a rubber composition comprising at least one elastomer and a filler.
- FIG. 1 shows - schematically - a rolling assembly according to the invention.
- This assembly comprises a tire 10 comprising two beads 20, a mounting rim 500 whose width LJ is equal to 55% of the maximum axial width L of the tire 10 inflated to its operating pressure, and two adapters 100 which provide the connection between the mounting rim 500 and the two beads 20 of the tire 10.
- Figure 2 shows another rolling assembly according to the invention. Unlike the roller assembly of FIG. 1, this rolling assembly comprises only one adapter 100.
- the width LJ is here equal to 70% of the maximum axial width L of the tire 10 inflated to its operating pressure.
- FIG. 3 shows a part of a rolling assembly according to the invention.
- This assembly comprises a tire 10, an adapter 100 and a mounting rim 500.
- the tire 10 is, as known, formed of a tread reinforced by a crown reinforcement of one or more layers of reinforcement elements (not shown) and joined to two beads on either side of the median plane through two sidewalls 30.
- a carcass reinforcement 60 mainly reinforcing the sidewalls 30 is anchored in each bead to at least one rod 70, here of type "braided” to form turns 62, separated from the main carcass reinforcement portion 60 by a stuffing 80.
- the mounting rim 500 is a rim of usual constitution with a groove 530 called “assembly" and bringing together, on either side of the equatorial plane, two seats of rim 510, whose frustoconical generatrices make with the axis of rotation an angle of 5 °, the seats being axially outward extended by rim flanges 520 whose radially outer edges are strongly curved.
- the particularity of the rim 500 is its axial width LJ, which is equal, in the case studied (with a tire of size 225/45 R17), to 140.5 mm, that is to say equal to 60% of the width axial maximum tire 10 mounted and inflated to its recommended pressure.
- an adapter 100 consisting mainly of a housing 140, joined to an adapter bead 120 by a connecting body 130.
- the housing reinforcement 141 metal in the example described but who could be made of plastic material or composite material such as a fiber-reinforced resin of any nature, is formed of an inclined seat 142, in this example and with respect to the axis of rotation of the assembly, of an angle of 5 °, and extended axially and radially outwardly by a flange 143, the dimensions of these elements being normalized, either the height of the flange 143 or the axial width of the seat 142.
- the walls of the housing reinforcement 141 are treated, for example brassed in the studied case of metal reinforcement, to allow a correct adhesion with the rubber compositions used in the main reinforcing armature 131 and any additional reinforcement of the adapter 100.
- the main reinforcing armature 131 is formed of a sheet of polyamide aromatic textile cables, parallel to each other in the sheet and radial, and this sheet is on the one hand contiguous axially to the interior. radially outwardly to the walls of the housing reinforcement 141 and further anchored in each adapter bead 120 to a circumferential anchoring ring 123, such as a bead wire, to form an upturn 124.
- the main reinforcing armature 131 is completed by additional reinforcements: in the bead 120 is disposed a first bead reinforcement ply 126, formed of an aliphatic polyamide fabric formed of wire reinforcing elements, parallel to each other in each layer of reinforcement; cloth and crossed between them; on the side of the housing reinforcement 141 of the adapter 100 is disposed an additional reinforcement 125 formed of a fabric identical to the previous one formed of two layers of textile elements of aliphatic polyamide, parallel to each other in each layer and crossed with a layer to the next, making an angle of 45 ° with the circumferential direction.
- This additional reinforcement 125 partly covers the axially inner wall and then the upper end then the axially outer wall of the flange 143 and finally the radially inner wall of the seat 142 to have an edge attached to the main reinforcing ply 131, whose end edge is spaced from the plane of the median plane by an amount less than the distance separating from this plane the axially inner end of the seat 142.
- a layer of rubber protective composition covers the outside of the housing reinforcement 141, the radially inner face of the seat.
- adapter 100 and provides the connection with the hook of the mounting rim 500 surrounding the armatures 131 and 126. On its radially inner face, intended to be in contact with the inflation gas of the assembly, the adapter 100 comprises a layer 128 of gas-impermeable rubber composition.
- the roller assembly of FIG. 4 differs from that of FIG. the tire, which has beads whose seats are inclined relative to the axis of rotation of the assembly by an angle equal to 20 °, and which are reinforced by rods of rectangular wire type;
- the mounting rim 500 which has a mounting groove 530 facing the inside of the assembly, seats 510 inclined relative to the axis of rotation by an angle of 15 °, the seats 510 being axially extended to the outside and radially inwards by rim flanges 520 with curved edges, the rim receiving the beads of the adapter from the inside;
- the adapter 100 which consists of:
- a housing reinforcement 141 formed of a seat 142 inclined relative to the axis of rotation of the assembly by an angle equal to 15 ° and extended axially and radially outwardly by a flange 143, the other dimensions of these elements being normalized, either the height of the flange 143 or the axial width of the seat 142;
- an additional reinforcement completing the main reinforcing armature 131 on the side of the housing reinforcement 141 of the adapter 100 is disposed an additional armature 125 formed of the same fabric as previously of textile elements, this armature 125 covering partially the axially inner wall and then the upper end and the axially outer wall of the flange 143 and finally partially the radially inner wall of the seat 142 to have an edge abutting the main reinforcing ply 131, the edge whose end is distant from the plane median of an amount less than the distance separating from this plane the axially inner end of the seat (142); (d) layers of rubbery composition on the one hand of protection, and on the other hand on its radially inner face by the inner layer 128 of gas-impermeable rubber composition.
- the roller assembly of Figure 5 differs from that of Figure 3 by the constitution of the adapter bead 120 and the constitution of the fastening system of the bead on the mounting rim 500.
- This system is in effect composed of two elements: the mounting rim 500 proper and a bead clamp 600.
- the rim 500 is formed of two usual flanges 520, extended radially inside and axially inside by two seats rim 510 flat , themselves extended radially inwardly by two radial annular disks 530 having between them a certain axial spacing.
- the radially movable discs 540 of at least three parts which, joined circumferentially, form the plate of the bead clamp 600, whose axial width is sufficient to allow the clamping and jamming of the beads on the seats
- the plate can also advantageously serve as a support for the tread of the tire of the assembly when the tire rolls at low or even zero pressure.
- the adapter bead 120 it is adapted with respect to its composition and shape to the attachment principle described above; in particular it is advantageous that the main reinforcing armature 131 of the adapter 100 is anchored by winding around a ring 123 of high compression modulus rubber but expandable in the circumferential direction.
- an additional reinforcement 125 formed of a fabric identical to the previous formed two layers of aliphatic polyamide elements, parallel to each other in each sheet and crossed with a layer to the next making an angle of 45 ° with the circumferential direction; this armature 125 partially covers the axially inner wall and then the upper end then partially the axially outer wall of the flange 143 to have an end located on the axis of rotation at a radial distance corresponding to the middle of the flange 143.
- the last example of a rolling assembly according to the invention is shown in FIG. 6.
- the tire is identical to that shown and used throughout FIG. 4.
- the mounting rim is a so-called multi-spoke rim. pieces, of which at least two pieces are movable.
- Such a rim is of the same type as the rims used for mounting certain "heavy-duty" tires and tires of "engineering- civil society.
- This rim is mainly composed of a rim base 300, which may be flat, this rim base 300 being extended on one side of the rim by a conical seat itself extended by a circle or rim flange, seat and flange being on this side and fixed (not shown).
- a single piece 310 mobile formed of a flange 320 and a conical ring 340, can be slipped on the bottom of the rim after the adapter bead 120 has itself been brought on the bottom of rim.
- An O-ring 350 to seal the assembly, and a locking ring 360 to lock the assembly on the bottom rim 300, complete the single piece 310.
- any bead adapter 120 of however it may be, can be mounted on such a rim.
- the example described relates to a preferred embodiment where the main reinforcing armature 131 of the adapter 100, composed of a sheet of radial textile cables, and its overturning 124 are sandwiched between the frustoconical seat of the mobile ring 340 and a reinforcing ring 370 having a radially inner face which is itself frustoconical, the generatrix of this face forming with the axis of rotation the same angle as that made by the generatrix of the seat of the movable conical ring of the single piece 310
- the overturning 124 of the main reinforcing armature 131 is obtained by winding this armature around a circumferential ring 123 having a small cross-sectional area and a low resistance to tension, this ring 123 being used only for complete the locking of the carcass reinforcement between the two frustoconical surfaces of the ring 370 and the conical ring seat 340.
- the guiding capacity of both was compared subjectively in tests performed on the circuit.
- the evaluation program included straight-line maneuvers such as slalom, lane changes or avoidance maneuvers, at speeds between 80 and 120 km / h.
- the testers gave their impressions without knowing the architecture of the rolling assembly.
- the curb impact resistance was quantified by passing the wheel sets on a sidewalk of 90 mm high with an angle of 30 ° by contribution to the direction of advance of the tire; successive passes are made at different speeds until the tire loses its inflation pressure or is deformed and the forces transmitted to the sidewalk are acquired for each passage.
- the rolling assembly according to the invention therefore makes it possible to very significantly improve the vehicle guidance while maintaining a very good impact resistance capacity.
