Abstract
A landing gear (1) includes a shock strut (2) having a cylinder (3) and a piston (4), and a wheel (5) supported on the piston. The shock strut has a steering mechanism (21) that turns the wheel about the strut axis (Z) together with the piston. A power source for the steering mechanism is an electric motor (6) having a rotor (61) and a stator (62), and the rotor and the stator are coaxial with the strut axis.
Claims6
A landing gear for an aircraft, comprising:
- a shock strut comprising a cylinder and a piston inserted into the cylinder and configured such that the piston is operable in a direction of a strut axis and is rotatable about the strut axis relative to the cylinder supported on an airframe;
- and
- a wheel supported on the piston,
- wherein the shock strut comprises a steering mechanism that turns the wheel about the strut axis together with the piston,
- a power source for the steering mechanism is an electric motor comprising a rotor and a stator,
- the rotor and the stator are coaxial with the strut axis,
- the shock strut comprises a shaft supported on the cylinder so as to rotate about the strut axis and protruding in a direction away from the piston from an end portion of the cylinder,
- the piston is engaged with the shaft in the cylinder so as to relatively move in the direction of the strut axis and integrally rotate in a rotational direction about the strut axis,
- the electric motor is located at the end portion of the cylinder, and
- the rotor is connected to a protruding portion of the shaft.
