Abstract
Official abstract text for this publication.
An aircraft wheel having a rim having brake discs driving keys ( 21 ). The wheel has a rotational driver mechanism ( 210 ) which includes a drive gear ( 211 ) associated with coupling members ( 212 ) of the drive gear to the rim of the wheel. The coupling members are fixed to the rim by fixing members ( 220 ) introduced into orifices of the rim extending at an end of the keys which are also used to hold heat shields protecting the rim.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aircraft wheel having a rim comprising brake disc driving keys ( 21 ), the wheel being provided with rotation drives ( 210 ) which comprise a drive gear ( 211 ) associated with coupling members ( 212 ) for coupling the drive gear to the rim of the wheel, the coupling members being fixed to the rim by fixing members ( 220 ) introduced into orifices of the rim extending at an end of the keys which are also used to hold heat shields protecting the rim. 2. The aircraft wheel according to claim 1 , wherein the fixing member comprises a screw ( 220 ) which extends to hold both one of the coupling members of the drive gear and one of the heat shields. 3. The aircraft wheel according to claim 1 , wherein the drive gear ( 211 ) comprises an annular disc ( 213 ) and the coupling members ( 212 ) are secured to the disc and the fixed to the rim. 4. The aircraft wheel according to claim 3 , wherein each coupling member comprises a flange ( 251 ) which is attached by the fixing member ( 220 ) to the rim, the flange ( 251 ) supporting a plate ( 255 ) on which is mounted the annular disc ( 213 ). 5. The aircraft wheel according to claim 4 , wherein the annular disc ( 213 ) is mounted on each plate ( 255 ) of the coupling members with elastomer stops ( 256 ) interposed between the disc ( 213 ) and the rim. 6. The aircraft wheel according to claim 3 , wherein the annular disc ( 213 ) is made of a material having the same flexibility as that of the rim to follow the deformations thereof. 7. Aircraft wheel according to claim 3 , wherein the annular disc bears a series of removable protrusions ( 214 ) forming the driving teeth of the rim during rotation.
