Abstract

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.

First claim

The invention claimed is:

1. An aircraft wheel comprising:
a rim, and a tyre ( 20 ; 120 ) received on the rim,
wherein the rim is in two parts ( 1 , 2 ; 101 , 102 ) assembled with one another by means of assembly bolts ( 5 ; 105 ), one of the parts comprising a recess ( 3 ; 103 ) in which is arranged a seal ( 4 ; 104 ) which is interposed between the two parts,
wherein at least one of the parts comprises at least one duct ( 6 ; 106 ) 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 two 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,
wherein the rim comprises two half-rims ( 1 , 2 ), each half-rim forming respectively one of the parts of the rim, and
wherein the duct ( 6 ) is cut into the half-rim comprising the recess ( 3 ), the duct opening into the recess.

2. The wheel according to claim 1 , in which the duct ( 6 ) has a bottom which is inclined relative to an axis of rotation (X) of the wheel.

3. The wheel according to claim 1 , formed such that the duct ( 6 ) opens at one end onto a face ( 13 ) of the half-rim ( 1 ) opposite the other half-rim ( 2 ).

4. The wheel according to claim 1 , in which one of the parts comprises a plurality of ducts ( 6 ; 106 ) each extending between two consecutive assembly bolts ( 5 ; 105 ).
