Abstract
The invention relates to an aircraft landing gear (2) comprising: —a leg (6) that can be pivotably connected to a load-bearing structure of the aircraft (1) in order for the landing gear (2) to be deployed and retracted; —a wheel (13, 14) that is rotatable in relation to the leg (6), and an electric motor (15, 16) that can rotate the wheel (13, 14) in relation to the leg (6); —a transmission mechanism (17) designed to selectively transmit torque generated by the electric motor (15, 16) to the wheel (13, 14) in order to rotate the wheel in relation to the leg (6) or to the leg (6) in order to rotate the leg (6) in relation to the load-bearing structure of the aircraft (1) in order to deploy or retract the landing gear (2).
Claims12
Landing gear for aircraft comprising:
- a leg suitable for being articulated on a bearing structure of the aircraft for deployment and retraction of the landing gear,
- a wheel movably mounted in rotation relative to the leg and an electric motor suitable for driving the wheel in rotation relative to the leg,
- a transmission mechanism comprising a transmission shaft extending inside the leg, said transmission shaft having a first end suitable for being coupled to the motor and a second end suitable for being coupled to the bearing structure of the aircraft,
- the transmission mechanism being configured to transmit torque generated by the electric motor selectively to the wheel to drive the wheel in rotation relative to the leg, or to the leg via the transmission shaft to drive the leg in rotation relative to the bearing structure of the aircraft to deploy or retract the landing gear.
