An aircraft wheel having a rim having brake discs driving keys (). The wheel has a rotational driver mechanism () which includes a drive gear () associated with coupling members () of the drive gear to the rim of the wheel. The coupling members are fixed to the rim by fixing members () introduced into orifices of the rim extending at an end of the keys which are also used to hold heat shields protecting the rim.

Aircraft wheel equipped with means for the rotational driving thereof by a drive actuator

An aircraft wheel equipped with rotation-drivers () attached to clevises () projecting from a side of wheel rim (). The rotation driver includes a ring () that is adapted to cooperate with a drive actuator and is provided with members () for attaching to the clevises in such a way that, between two attachment members, the ring forms a flexible and deformable segment.

Aircraft wheel with rotational drive attached to clevises projecting from wheel rim

An aircraft landing gear including an axle and a wheel () that includes a rim () mounted to turn on the axle about a first rotation axis (X), the landing gear further comprising an actuator () for driving the wheel () in rotation. The rim () includes obstacles () that project from a lateral face (F) of the rim and the driving actuator includes a lead screw () mounted to turn about a second rotation axis (X) perpendicular to the first rotation axis (X) and adapted to cooperate with the obstacles of the rim to drive the wheel in rotation.

Aircraft landing gear equipped with wheel driving means

A landing gear that comprises an axle () and a wheel (). The wheel comprises a rim () mounted so as to rotate on the axle about a first axis of rotation (X), first blocks protruding from a lateral face (F, F') of the rim, the first blocks being adapted to cooperate with a gearwheel () of a drive actuator () carried by the landing gear. The gearwheel is mounted rotatably about a second axis of rotation (Y) perpendicular to the first axis of rotation.

Aircraft landing gear equipped with means for driving in rotation wheels carried by the landing gear

An aircraft wheel which is provided with rotational driving unit (). The driving unit comprises a driving ring () which is associated with structure () for attaching the ring to a rim of the wheel. The attachment structure is fixed to treads () of the rim which further serve to retain removable brake blocks () with which the rim is provided.

Aircraft wheel

The invention relates to a device for driving rotation of an aircraft wheel comprising a rim () mounted to rotate on an axle () of landing gear about an axis of rotation (X), the device comprising a drive ring gear () and a drive actuator () having an outlet pinion () that co-operates with the drive ring gear to drive the wheel in rotation. The drive ring gear is mounted to rotate about the axis of the rim of the wheel, the drive device including selective coupling means () that are operable to link the rim and the drive ring gears together in rotation, or to disconnect them.
