Abstract

An aircraft wheel comprising two half-wheels ( 1, 2 ) assembled together by means of bolt fasteners ( 10; 110 ) clamping together disks of the half-wheels, each bolt fastener comprising a bolt ( 11; 111 ) with an end forming a screw head ( 12; 112 ) and a threaded end ( 13; 113 ) for receiving a nut ( 14; 114 ), the wheel also being fitted with drive keys ( 20; 120 ) that are fitted to one of the half-wheels for driving brake disks in rotation, the wheel being characterized in that each drive key has a first end ( 23; 123 ) that is shaped to co-operate with the screw head of one of the bolts so that said first end is held and prevented from moving when the key is in place on the wheel.

First claim

The invention claimed is:

1. An aircraft wheel comprising two half-wheels ( 1 , 2 ) assembled together by means of bolt fasteners ( 10 ; 110 ) clamping together disks of the half-wheels, each bolt fastener comprising a bolt ( 11 ; 111 ) with an end forming a screw head ( 12 ; 112 ) and a threaded end ( 13 ; 113 ) for receiving a nut ( 14 ; 114 ), the wheel also being fitted with drive keys ( 20 ; 120 ) that are fitted to one of the half-wheels for driving brake disks in rotation, the wheel being characterized in that each drive key has a first end ( 23 ; 123 ) that is shaped to co-operate with the screw head of one of the bolts so that said first end is held and prevented from moving when the key is in place on the wheel.

2. A wheel according to claim 1 , wherein the first end ( 23 ) is cylindrical in shape and penetrates into a central orifice formed in the screw head ( 12 ) of the bolt.

3. A wheel according to claim 1 , wherein the key has a second end ( 24 ) that is pierced to receive a bolt ( 25 ) for fastening said end to an extension ( 26 ) projecting axially from the half-wheel.

4. A wheel according to claim 1 , wherein the bolts ( 111 ) of the fastener bolts and the drive keys ( 120 ) are made integrally.

5. A wheel according to claim 4 , wherein the first end of the drive key is formed integrally with the screw head of the bolt.

6. A wheel according to claim 4 , wherein each key has a second end carrying two projections ( 125 ) adapted to be fitted astride a facing boss on the rim of the half-wheel.
