    专利说明:

    [0001] The invention relates to an aircraft wheel rim with removable heel. BACKGROUND OF THE INVENTION Wheel rims are already known for receiving a tire and comprising two heels, one of which is removable. This type of rim comprises an outer portion of revolution bearing a first heel integral with the rim and a second removable heel which is attached to the outer portion and held in position by a rod immobilized by a shim. The arrangement of this type of rim makes it possible to mount a tire by sliding it around the outer portion and then mounting the removable bead on the rim so as to enclose the two beads of the tire between the lugs of the rim. The structure of the rim thus allows mounting and dismounting of the tire while the rim is fixed on an axle, such as an aircraft landing axle. There has been identified a risk of rotation of the removable heel relative to the rest of the rim, which may cause deterioration of the interface between the two elements, leading to performance losses. To reduce this risk, the document FR2976216 proposes the use of a special rod capable of developing radial forces preventing rotation of the removable heel. It has also been proposed to cooperate the heel and the rest of the rim in a non-circular range, thus ensuring a locking rotation of the removable heel. It has also been proposed in FR2966078 to provide the removable heel teeth, the angular locking being obtained by inserting a shim in the space between two teeth. These angular blockages, besides being limited in mechanical strength, are expensive to produce, and difficult to control by an operator.
    [0002] OBJECT OF THE INVENTION The subject of the invention is a rim with a removable heel whose antirotation device of the removable heel is simple and easily controllable.
    [0003] PRESENTATION OF THE INVENTION With a view to achieving this object, a two-part aircraft wheel rim is proposed, of which a main part comprises a hub, a sail extending between the hub and an annular external portion designed to accommodate it has a tire and shaped to present a stud at one of its ends, the other of its ends being shaped to receive a removable portion forming a heel which is attached to the annular outer portion after placing the tire, the rim having locking means in rotation of the removable heel relative to the rim. According to the invention, the rotational locking means comprise at least one rod having a first end coupled to the main part, and a second end coupled to the removable part, the ends having centers which define an axis which extends in a plane perpendicular to an axis of rotation of the rim while extending obliquely to make an angle relative to a radial direction.
    [0004] Thus, the removable heel and the main part of the rim can cooperate in annular surfaces very simple to produce, while the locking in rotation is obtained by the interposition of a rod which remains very visible from the outside, which facilitates inspection of the rim. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood in the light of the following description of various particular embodiments of the invention, with reference to the figures of the attached drawings, in which: FIG. 1 is a sectional view of FIG. a rim with removable heel according to a first particular embodiment of the invention; - Figure 2 is a perspective view of the rim of Figure 1; - Figure 3 is an exploded detail view of the rim of Figure 2; - Figures 4 to 7 are schematic diagrams illustrating various embodiments of the invention.
    [0005] DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS OF THE INVENTION With reference to FIG. 1, the invention applies to rims comprising a main part 1 which comprises a hub 2 adapted to receive rotating guide rollers (not shown) about an axis of rotation X, and an outer annular portion 3 connected to the hub 2 by a web 4. One of the axial ends of the outer annular portion 3 is shaped as a bead 5 while the other end is formed as a centering surface 6 of a removable auxiliary portion 10 of generally annular shape which has a centering surface 11 and a heel-shaped end 12. Here, the centering surfaces 6 and 11 are of revolution. In a manner known per se, the removable auxiliary part 10 is attached to the main part 1 after placing a tire on the outer annular portion 3, as shown. A rod 13 is then interposed between the main part 1 and the removable auxiliary part 10 to axially connect these two parts to each other. According to the invention, and as can be seen in FIGS. 2 and 3, the main part 1 comprises reservations 7 in each of which an orifice 8 has been arranged in an axial direction. Likewise, the removable heel 10 includes reservoirs 14 in each of which an orifice 15 has been arranged in an axial direction. The orifices 7, 14 adjacent receive fasteners 9 and 16 of the ends of a rod 20. Here, each of the rods 20 is cut in a metal plate. The axis defined by the centers of the ends of the link 20 extends here substantially in a plane P perpendicular to the axis X, and in a direction making an angle 13 non-zero with respect to a radial direction. Preferably, the angle 13 is between 45 and 90 degrees. Thus arranged, each link 20 acts as a stop in rotation of the removable heel 10 on the main part 11, and is perfectly visible from the outside, so that the control of its presence is facilitated.
    [0006] The rim is here equipped with two rods 20 mounted in diametrically opposite regions, and making opposite angles with radial directions. Figures 4 to 7 show alternative embodiments of the invention. In Figure 4, the rim is equipped with a single rod 20. In Figure 5, the rim is equipped with three rods 20 evenly distributed, and all having the same angle 13 relative to radial directions. In Figure 6, the rim comprises two rods 20 which converge at their ends connected to the removable auxiliary portion 10, being associated with a common fastener. In Fig. 7, the two convergent link diagram of Fig. 6 was repeated three times. The invention is not limited to what has just been described, but on the contrary covers any variant within the scope defined by the claims.
