The invention relates to an aircraft undercarriage including at least one axle having at least one wheel mounted to rotate thereon, the undercarriage including a communication device for connecting a sensor mounted on a rim of the wheel to stationary processor means mounted on the aircraft. According to the invention, the communication device comprises firstly an antenna secured to the sensor and thus rotating together with the wheel, and secondly a stationary antenna extending at the end of the axle and connected to the processor means, the two antennas being in radio communication through a cover of non-conductive material secured to the wheel and covering the end of the axle.

Undercarriage fitted with a communication device between a wheel and the undercarriage

The invention relates to axle end equipment for a vehicle, in particular an aircraft, the equipment comprising a stationary portion for securing to the axle and a rotary portion for securing to the wheel carried by the axle. According to the invention, the rotary portion comprises first remote connection means in communication with a sensor mounted on the wheel so as to put the sensor and the rotary portion of the equipment into contactless electromagnetic relationship.

Axle end equipment for a vehicle, in particular an aircraft

A tachometer for an aircraft wheel mounted on an axle to rotate about an axis of rotation. The tachometer has a stationary part secured to the axle and a rotary part driven in rotation by the wheel. The stationary part and the rotary part are mountable independently on the axle and on the wheel, respectively, and have portions facing each other in a radial direction. A sensor and a target element carried by the stationary and rotary parts portions that extend facing each other in a radial direction and are in register with each other in a radial direction. The portion secured to the rotary part extends inside the axle.
