Abstract

A method for fixing to an aircraft landing gear ( 1 ) at least one actuator ( 30 ) for rotatably driving a wheel ( 3 ) which is rotatably mounted on an axle ( 2 ) of the landing gear, the wheel being associated with a brake ( 5 ). The brake has an actuator carrier ( 8 ) which carries brake actuators, the actuator carrier being fitted onto the axle and stopped in terms of rotation by an obstacle ( 12 ) which is fixedly joined to the landing gear and which is introduced into one of several stop holes ( 11 ) of the actuator carrier. The drive actuator is fixedly joined to the actuator carrier in the region of a stop hole of the actuator carrier which does not receive the obstacle.

First claim

The invention claimed is:

1. A method for fixing to an aircraft landing gear at least one actuator for rotatably driving at least one wheel which is rotatably mounted on an axle of the landing gear, the wheel being associated with a brake which comprises an actuator carrier having a plate which carries brake actuators, and which has two rotation stop holes so that, when the actuator carrier is fitted onto the axle, it is stopped in terms of rotation by an obstacle which is fixedly joined to the landing gear and which is introduced into one of the stop holes of the plate, characterised in that it comprises the steps of attaching and fixing the drive actuator to the actuator carrier by means of the stop hole of the plate which does not receive the obstacle.

2. The fixing method according to claim 1 , comprising the step of fixing the drive actuator to the actuator carrier of the brake when said actuator carrier is mounted on the axle of the landing gear.

3. A drive actuator which is specifically adapted to the implementation of the method of claim 1 , comprising an output shaft which is provided with an output pinion in order to engage with a drive ring of the wheel, wherein the output shaft opens from a protrusion which is provided for being engaged in the stop hole of the actuator carrier.

4. A method for fixing to an aircraft landing gear at least one actuator for rotatably driving at least one wheel which is rotatably mounted on an axle of the landing gear, the wheel being associated with a brake which comprises an actuator carrier having a plate which carries brake actuators, and which has two rotation stop holes so that, when the actuator carrier is fitted onto the axle, it is stopped in terms of rotation by an obstacle which is fixedly joined to the landing gear and which is introduced into one of the stop holes of the plate, the method comprising the steps of:
attaching and fixing the drive actuator to the actuator carrier by means of the stop hole of the plate which does not receive the obstacle, wherein the drive actuator comprises a protrusion which is provided for being introduced into the stop hole of the actuator carrier, and
introducing said protrusion into the stop hole of the actuator carrier.

5. The fixing method according to claim 4 , comprising the step of fitting an immobilisation plate at the end of the protrusion, when said protrusion is engaged in the stop hole.

6. A method for fixing to an aircraft landing gear at least one actuator for rotatably driving at least one wheel which is rotatably mounted on an axle of the landing gear, the wheel being associated with a brake which comprises an actuator carrier having a plate which carries brake actuators, and which has two rotation stop holes so that, when the actuator carrier is fitted onto the axle, it is stopped in terms of rotation by an obstacle which is fixedly joined to the landing gear and which is introduced into one of the stop holes of the plate, the method comprising the steps of:
engaging two ends of a cradle in the stop holes of actuator carriers of brakes of wheels which are carried by a same axle, the drive actuator being attached to the cradle.
