Patent ID: 7854411

Claim:
An aircraft undercarriage comprising: a steerable bottom portion, and a steering member suitable for turning the steerable bottom portion in response to a steering order, wherein the steering member comprises a plurality of electromechanical steering actuators each comprising at least one main electric motor, wherein the actuators are disposed on the undercarriage so as to enable all of them said actuators to co-operate simultaneously with the steerable bottom portion in order to steer said bottom portion, and wherein each of the electromechanical steering actuators includes a controllable coupling means for selectively placing the actuator: either in a coupled state in which said actuator is coupled with the steerable bottom portion, in which the main electric motor of the actuator is suitable for causing the steerable bottom portion to turn; or in an uncoupled state in which said actuator is uncoupled from the steerable bottom portion and in which the main electric motor of the actuator is isolated from the steerable bottom portion.
