Abstract
A multifunction device for an undercarriage. The device comprises at least a first shaft rotatably mounted on the aircraft to rotate about an axis of rotation that is substantially parallel to a hinge axis hinging the undercarriage to the aircraft, and a telescopic second shaft rotatably mounted in the undercarriage and extending down along the undercarriage to the proximity of wheels carried thereby. A motor is adapted to cause the first shaft to rotate. The telescopic second shaft is a single shaft that extends inside the undercarriage to the proximity of an axle carrying the wheels of the undercarriage. The second shaft is connected to a differential connected to the wheels via drive shafts extending inside the axle.
Claims9
A multifunction device for an undercarriage, the multifunction device comprising at least:
- a first shaft rotatably mounted on an aircraft to rotate about an axis of rotation that is substantially parallel to a hinge axis hinging the undercarriage to the aircraft;
- a telescopic second shaft rotatably mounted on the undercarriage and extending along a member of the undercarriage;
- first transmission equipment for transmitting rotary motion from the first shaft to the telescopic second shaft;
- second transmission equipment for transmitting rotary motion from the telescopic second shaft to at least one wheel of a plurality of wheels carried by the undercarriage;
- a brake for selectively braking said at least one wheel;
- and
- a motor adapted to cause the first shaft to rotate;
- the multifunction device being characterized in that the telescopic second shaft is a single shaft and it extends inside the member of the undercarriage in direction of an axle carrying said wheels of the undercarriage, the second transmission equipment including a differential connected to the wheels carried by the axle via drive shafts extending inside the axle.
