    [0001] The invention relates to a method for rotating an aircraft wheel. TECHNOLOGICAL BACKGROUND OF THE INVENTION It is increasingly envisaged to equip the aircraft with wheel rotation drivers for moving the aircraft while its powertrains are inactive. In general, the drive member comprises an electric motor associated with a gear and equipped with an output gear which cooperates with a drive ring secured to the rim of the wheel. However, the fastening of the crown on the rim requires to provide on the latter specific screeds on its periphery, which requires the production of specific rims. Most often, with the rims of aircraft wheels of a certain size, the rims comprise two half-rims assembled together by a series of bolts. OBJECT OF THE INVENTION The subject of the invention is a method for rotating an aircraft wheel by means that requires little or no modification of existing rims. PRESENTATION OF THE INVENTION With a view to achieving this object, a method of driving in rotation of an aircraft wheel is proposed, the wheel being equipped with a rim comprising two half-rims assembled by bolts, in which which a drive member is controlled to generate a driving torque of the wheel. According to the invention, the driving torque is transferred to the wheel via the assembly bolts of the rim. Thus, the torque is transferred to the wheel by the assembly bolts of the rim, which does not require otherwise to change the half-rims. It suffices to adapt the bolts, or to provide output device interfaces capable of adapting to said bolts to drive the wheel provided with its usual rim. According to a preferred embodiment, there is provided a coupling ring between a rotor of a motor of the drive member and the bolts of the rim. The coupling ring achieves both the transmission of torque and the damping of transmission knocks. PRESENTATION OF THE FIGURES FIG. 1 is an exploded perspective view of the bottom of an aircraft undercarriage equipped with a rotary drive member coupled to the adjacent wheel by means of the method of the invention; FIG. 2 is a perspective view of the interfacing member extending between the driving member and the rim of the wheel; - Figure 3 is a sectional view of the undercarriage of Figure 1; FIG. 4 is a perspective view of a drive member provided with an interface member for transmitting the torque via the wheel rim assembly bolts, according to an alternative embodiment. of the invention; FIG. 5 is a perspective view of an aircraft wheel equipped with the interface member of FIG. 4. DETAILED DESCRIPTION OF A MODE FOR CARRYING OUT THE INVENTION Referring to FIG. , the method of the invention is here implemented on a landing gear 1 which can be seen here the lower part equipped with an axle 2 on which a wheel 3 is mounted to rotate. The wheel comprises a rim 4 formed of two half-rims 4a, 4b assembled by bolts 5 each comprising a screw and an associated nut. The rim 4 is guided 3024706 3 rotation on the axle 2 by means of bearings 6, and carries a tire 7. The undercarriage is equipped with a drive member in rotation of the wheel 3 essentially comprising an electric motor 10 mounted at the end of the axle 2. The motor 10 comprises a stator 11 which is directly fixed to the axle 3. The stator carries coils 12 at its periphery. The motor 10 also comprises a rotor 13 which comprises a hub 14 rotatably mounted on the stator, here by means of bearings. The rotor 13 comprises a drum 15 which extends around the stator and which carries permanent magnets 16. The drum 15 is connected to the hub 14 by a flange 17 which also serves as a protective cover for the motor 10. The circulation of a current in the coils adapted to create a rotating magnetic field induced on the drum a mechanical torque driving the rotating drum. When the motor 10 is in position on the axle 3, the axis of rotation of the rotor 13 coincides with the axis of rotation of the wheel 3. The drum 15 carries a plurality of tie rods 18 which extend parallel to each other. the axis of rotation of the rotor 13, substantially opposite the bolts 5. The drum thus forms the output member of the drive member. An interface member 20 extends between the tie-rods 18 and the bolts 5 to rotate the drum 15 of the rotor 13 and the wheel 3. As can be seen more particularly in FIG. 2, the interfacing member 20 comprises two coaxial rings 21 connected by crosspieces 22. Each ring 21 carries a plurality of bushings 23 and 24 adapted to receive respectively the ends of the tie rods 18 and the screws of the bolts 5, as can be seen in FIG. nuts are placed on each tie and each screw to secure the interfacing member 20.
    [0002] Thus, the bolts 5 enclose the two half-rims and the sockets 24 of the interfacing member 20. The interfacing member 20 makes it possible to transmit the torque of the rotor 13 to the wheel 3 to drive the wheel in rotation. It will be noted that its structure is intentionally flexible so as to enable it to absorb the jolts of transmission and the relative movements between the wheel 3 and the rotor 13 due in particular to the bending of the axle and the deformation of the rim during the rolling of the aircraft.
    [0003] The torque of the motor 10 is thus transmitted to the wheel 3 via the bolts 5 which connect the half-rims 4a, 4b to each other. Thus, it is possible to use half-rims without any modification, the half-rims being largely dimensioned to receive the torque via the assembly bolts. It will suffice to choose screws a little longer than the usual screws and nuts adapted to facilitate interfacing with the drive member. According to a variant of the invention illustrated in FIGS. 4 and 5, the interfacing member 120 here comprises three stirrups 121 each comprising a bridge 122 connecting two arms 123 terminated by tabs 124. The tabs 124 are attached to the rim 4 by means of the assembly bolts 5 and are fixed to the rotor 13 by the tie rods 18. The rotor is thus connected to the rim via the interface member 120 which transmits the torque of the engine via the assembly bolts of FIG. the rim. Note that the stirrups can be mounted in the other direction, the tabs being fixed to the rotor, while the bridge is fixed to the rim. The invention is not limited to what has just been described, but encompasses any variant within the scope defined by the claims. In particular, although in the illustrated example, the drive member 35 is placed outwardly of the rim so that the inside is free to receive brake disks, the drive member can be placed inward of the rim, while being interfaced with the wheel by its assembly bolts.
    [0004] Although here the rotor of the motor of the drive member is directly interfaced to the bolts of the rim, so as to be in direct contact with the wheel, it will of course be possible to intercalate a gearbox, for example of epicyclic type, whose output member will be interfaced to the bolts of the rim. Finally, any other type of interface may be considered between the output of the drive member and the assembly bolts of the rim. In particular, the output of the drive member may be provided with single orifices adapted to receive the ends of the screws of the assembly bolts of the rim, so that the disassembly of the drive member does not require of uncoupling operation between the drive member and the wheel. 20
