An aircraft undercarriage including a wheel, a support, a drive system, a mover system, a first pair of links, and a locking actuator. The drive system drives rotation of the wheel and is mounted to move relative to the support between an engaged position and a disengaged position. The mover system moves the drive system between the engaged and disengaged positions. The first pair of links are hinged to each other about a first hinge axis to pivot during the movement of the drive system between the engaged and disengaged positions. The locking actuator acts on a first target to lock or unlock the drive system. The first target is carried by one of the links.

Wheel actuator locking mechanism

An aircraft wheel comprising a hub for mounting the wheel on a landing gear axle for rotation, and a rim with edge flanges for receiving a tire, the rim being secured to the hub by a web. The hub receives releasably a bearing box comprising two bearings, each having an inner and an outer ring mounted between a bushing for engaging on the axle with an outside wall shaped to receive the inner rings, the bushing having one end shaped as an abutment and another end shaped to receive a pre-loading nut. A sleeve extends around the bushing and has (1) an inside wall with shoulders to hold the outer rings axially and (2) an outer wall shaped to be received as a sliding fit in a bearing of the hub, with one end shaped as an abutment and another end shaped to receive a stop nut.

Aircraft wheel with a separable bearing box

A landing gear () for an aircraft comprising a wheel (R), a system () for rotationally driving the wheel that is mobile between a clutched position and a safety position by passing through a declutched position, and a manoeuvring system () to displace the driving system () between its declutched and clutched positions. The gear comprises an elastic return () for returning the driving system () to its safety position and first and second abutments () that are separated as long as the driving system () is away from its safety position and in contact with one another when the driving system () is in safety position. The first and second abutments () oppose the passing of the driving system () from its safety position to its declutched position when the abutments are in contact with one another.

The invention relates to a method for connecting in rotation an output member () of an electric motor () and an element () that is to be driven in rotation, comprising the use of at least one fusible pin () that links the output member and the element that is to be driven, and that has at least one section that is prone to fail in shear when a torque transmitted by the fusible pin exceeds a predetermined threshold. The method comprises the step of interposing, between the pin and either the output member or the element that is to be driven, at least one elastic member () comprising a first travel with a first stiffness followed by a second travel with a second stiffness greater than the first stiffness.
