Protector shield for a sidewall of a motor vehicle tire, and a wheel assembly for such a vehicle incorporating it
The present invention relates to a protector shield for at least one sidewall of a motor vehicle tire, and to a wheel assembly for a motor vehicle incorporating this protector shield. The invention particularly but non exclusively concerns the fire protection against flames and/or said flammable substances, such as oil or Molotov cocktails, as well as a high solvent and/or acid resistance, especially in hostile environments. A protector shield of the invention is in a form of a curved ring designed to be mounted on a wheel rim receiving said tire and, according to the invention, the shield includes a fire protection part which defines an outer convex face of said shield and which comprises a cross-linked rubber composition which particularly exhibits flame retardant and heat resistance properties for imparting to said tire an improved fire protection against flames and/or flammable substances.
Aircraft wheel comprising a duct establishing a leakage path in the wheel
The invention relates to an aircraft wheel comprising a rim and a tire (20) received on the rim, the rim comprising two parts (1; 2) assembled with one another by means of assembly bolts (5), one of the parts comprising a recess (3) in which is arranged a seal (4) which is interposed between the two parts, the wheel being characterized in that at least one of the parts comprises at least one duct (6) extending beneath the seal so as to establish a leakage path between on one hand a volume of gas delimited by the rim and the tire, and on the other hand a space between the parts, the path being nominally closed by the seal when the bolts are tightened correctly but allowing gas to leak from said volume when the bolt associated with said opening is not tightened correctly or is absent.
Mismatch side rim and lock ring interface angles for lock ring wheel
Systems and methods disclosed herein may be useful for use in a wheel assembly. In this regard a wheel assembly may comprise a wheel base with a center axis, a side rim disposed about a circumference of the wheel base, wherein the side rim includes a frustoconical radially inward surface, and a lock ring comprising a single unitary member. The lock ring may secure the side rim onto the wheel base, the lock ring preventing the side rim from sliding axially with respect to the wheel base, wherein a frustoconical radially outward surface of the lock ring comprises a first angle with respect to the frustoconical radially inward surface of the side rim.

AIRCRAFT WHEEL COMPRISING A DUCT ESTABLISHING A LEAKAGE PATH IN THE WHEEL
The invention relates to an aircraft wheel comprising a rim and a tyre (20) received on the rim, the rim comprising two parts (1; 2) assembled with one another by means of assembly bolts (5), one of the parts comprising a recess (3) in which is arranged a seal (4) which is interposed between the two parts, the wheel being characterized in that at least one of the parts comprises at least one duct (6) extending beneath the seal so as to establish a leakage path between on one hand a volume of gas delimited by the rim and the tyre, and on the other hand a space between the parts, the path being nominally closed by the seal when the bolts are tightened correctly but allowing gas to leak from said volume when the bolt associated with said opening is not tightened correctly or is absent.
