An installation for measuring the pressure of at least one tire of a wheel of an aeroplane includes: at least a pressure measuring sensor associated with a tire; a unit operating on the pressure measurement provided in the aeroplane; and radio-frequency transmission elements including for the or each sensor, a revolving antenna borne by the wheel and connected to each measuring sensor and to a fixed antenna connected by a conductive cable to the unit operating on the pressure measurement. The fixed antenna is adapted to be borne by the aeroplane structure away from the or each wheel at least in an upper part of the shock strut of the landing gear bearing the wheel.

Installation for measuring pressure of at least one aeroplane wheel tire

A wheel assembly includes a wheel having a rim which is adapted to receive a tire. The wheel carries a sensor for measuring pressure inside the tire. The wheel is mounted so as to rotate around a spindle. In addition a communication device is located between the sensor and a device which is associated with the spindle for using measurements that are performed by the sensor. The communication device comprises a radio transmission device which includes a rotary antenna carried by the wheel and a fixed antenna that is carried by the spindle.

Wheel assembly provided with a pressure sensor

A wheel arrangement includes a wheel having a sensor for measuring pressure in the tyre; a spindle, about which the wheel is rotatably mounted with the aid of bearings around the spindle, and of communication elements between the sensor and elements for using measures, which are associated with the spindle. Communication elements are adapted to a transmission system with a frequency higher than 50 kHz comprising a rotating antenna which is supported by the wheel and a fixed antenna. The two antennae do not have their own rotational guiding element. The antennae are generally annular and disposed in a concentric manner on the same level around the wheel axis (X-X) of rotation, the average radial distance between the antennae exceeding 2 mm.
