    ADAPTER FOR ROLLING ASSEMBLY AND ROLLING ASSEMBLY COMPRISING SAME
    The invention relates to an adapter for a roller assembly formed mainly of a tire and a rim, and a roller assembly comprising said adapter.
    The following are the definitions used in the present invention: - "axial direction": direction parallel to the axis of rotation of the tire, - "radial direction": direction intersecting the rotational axis of the tire and perpendicular thereto - "circumferential direction": direction perpendicular to a radius and lying in a plane perpendicular to the rotational axis of the tire, "radial section": section along a plane that contains the rotational axis of the tire, "equatorial plane": plane perpendicular to Rotation fee and which passes through the middle of the tread [0003] In the application WO2015091618 it is already known to insert, between the rim and the beads of a tire, an elastic adapter. This adapter is elastically deformable, in the radial and axial directions. Such an adapter makes it possible to dissociate the portion of the roller assembly that can be considered as actually working as a tire, the part of the roller assembly that can be considered to work as a rim.
    [0004] But if such an assembly also makes it possible to perform the functions of a conventional tire, and in particular a tire drift thrust response according to the application of a drift angle to the tire, which thus allows the assembly to sufficient flexibility to avoid any surface degradation or depth, it has an insufficient endurance in the duration at very high speed.
    Also it remains the need to have a new adapter that allows to provide better endurance in time running at very high speed such as 250km / h without degradation of the internal structure of the adapter.
    The invention therefore relates to an adapter for a roller assembly having an axis of rotation and comprising: - a tire having two beads, and - a rim, said adapter ensuring the junction between one of the beads and the rim, said rim having two rim seats, said adapter having: - an axially inner end to be mounted on the rim seat and comprising an inner reinforcing member, said reinforcing member having a center Ci, - an axially outer end comprising an outer reinforcing element, said reinforcing element having a center Ci, - a body connecting said outer end with said inner end so as to form a unitary piece and comprising at least one reinforcing reinforcement ensuring the connection between said outer reinforcement and said inner reinforcement, - a substantially cylindrical adapter seat for receiving one of said flock let, said seat being located at the axially outer end of said body. an adapter bearing face substantially comprised in a plane perpendicular to the axis of rotation, said bearing face being located on the axially inner face of the axially outer end, a total length L and a length LT between centers Ci and Ci.
    The adapter is characterized in that the first end and the second end of the reinforcing armature are arranged one on the other so as to form a covering.
    The adapter according to the invention has the advantage of being simple constitution and assembly. The adapter according to the invention also makes it possible to ensure sufficient coupling because the superimposed parts of the ply guarantee sufficient coupling.
    Another object of the invention is a rolling assembly having an axis of rotation and comprising; a tire having two beads, a rim, said adapter providing the junction between one of the beads and the rim, said rim having two rim seats, said adapter having: an axially inner end intended to be mounted on the seat; of the rim and comprising an inner reinforcing member, said reinforcing member having a center Ci, - an axially outer end comprising an outer reinforcing member, said reinforcing member having a center Ci, - a cock) connecting said outer end with said inner end so as to form a unitary piece and comprising at least one main reinforcing armature providing the connection between said outer reinforcement and said inner reinforcement, - a substantially cylindrical adapter seat for receiving one of said beads, said seat being located at the axially outer end of said body, i an adapter substantially in a plane perpendicular to the axis of rotation, said bearing face being located on the axially inner face of the axially outer end, - a total length L and a length LT between the centers Ci and Ci.
    This rolling assembly is characterized in that the first end and the second end of the reinforcing armature are arranged one on the other so as to form a covering.
    The axially outer end of the adapter defines, axially, a "housing for receiving the bead of the tire." The bearing surface of the axially outer end serves to support, in the axial direction, the bead of the tire like a rim hook.
    Thus the housing receives the tire bead just as conventionally the seat of a rim. The tire is then immobilized axially by the inflation pressure, and is pressed against the bearing surface of this axially outer end, as is conventionally done for the bead of a tire against the rim hook. a rim.
    The axially inner end of the adapter could be called "adapter bead" since it is intended to hang the adapter on the rim of a rim hook like what is conventionally done by the bead of a tire.
    Preferably, the covering has a length "1" greater than or equal to 0.2L and less than or equal to 0.5L.
    Preferably, the covering has a length "1" less than or equal to 0.6LT.
    Preferably, the reinforcement comprises a sheet comprising reinforcements coated with an elastomeric composition, said reinforcements being parallel to each other and forming an angle between 0 ° and 90 ° with the circumferential direction. More preferably, the reinforcements form an angle of between 30 ° and 60 ° with the circumferential direction.
    Reinforcements may have a pitch between 0.3 times the diameter of the reinforcement and 3 times the diameter of the reinforcement.
    The reinforcements may be chosen from reinforcements such as textile (PET, polyester, rayon), metal or fibers (carbon, glass) / resin.
    The outer reinforcement disposed at the outer end may be substantially of revolution about an axis and may comprise an inner layer and an outer layer comprising at least one outer layer of wire wound helically around the inner layer on several circumferential windings, the outer layer son or son comprising the first portion coated by the first coating.
    By circumferential winding means a winding around the main axis of the reinforcing member and extending in the circumferential direction about this axis. The outer layer being helically wound around the outer layer, each circumferential winding oscillates on either side of a median plane (that is, passing through the center of the inner layer) substantially perpendicular to Tax of the reinforcement element.
    Preferably, the outer reinforcement comprises an intermediate layer comprising at least one intermediate layer of wire wound helically around the inner layer on a plurality of circumferential windings, the outer layer or son being helically wound around the intermediate layer. on several circumferential windings.
    The outer reinforcement may also be substantially of revolution about an axis and may comprise a plurality of circumferential windings of at least one wire arranged axially next to one another on several layers radially superimposed on each other.
    When the assembled assembly comprises two adapters, the latter may be symmetrical or non-symmetrical. The notion of symmetry or dissymmetry of the adapter is defined by the axial length of the body of the adapter. Two adapters are asymmetrical when the body of one of them has an axial length greater than that of the other.
    Preferably, the rolling assembly according to the invention comprises a first and a second adapter each having a body of different or identical length.
    The invention will now be described with the aid of the examples and figures which follow and which are given purely by way of illustration, and in which: FIG. 1 schematically represents in radial section a tire; mounted on two adapters according to the invention, themselves embedded on the rim removably.

    Figure 3 differs from Figure 2 in that the first end 17A is disposed radially inside the second end 17B. The end 17A is sandwiched between the web portion 17C and the web portion 17D.
    In FIGS. 2 and 3, the overlap zone is disposed radially outside the portion 17C of the ply 17.
    In FIGS. 4 and 5, the overlap zone is disposed radially inside the portion 17C of the ply 17.
    Figure 4 is the counterpart of Figure 3. The end 17A is sandwiched between the web portion 17C and 17D web portion.
    Figure 5 is the counterpart of Figure 2. The end 17B is sandwiched between the web portion 17C and 17D web portion.
    In FIGS. 5 and 6, the overlap zone is arranged radially to the outer reinforcing element 20. In FIG. 5, the end 17A is sandwiched between the portion 17C and the external reinforcing element. 20. In FIG. 6, the end 17B is sandwiched between the part 17D and the external reinforcing element 20.
    The following example shows the results obtained with the adapter according to the invention.
    Example: High speed endurance trials
    This test consists of rolling the wheel with an initial speed of 250km / h and increasing this speed by 2km / h for 20h to obtain a final speed of 290km / h.
    An adapter according to the invention has a total length L = 65.35 mm and a recovery length l = 30 mm or 45% of the total length.
    It is observed that a wheel equipped with such an adapter carries out the test without any damage in contrast to a wheel comprising a known adapter without covering the reinforcing armature.
