Patent ID: 6843114

Claim:
Wheel arrangement ( 10 ) comprising: a wheel ( 14 ) provided with a rim ( 23 ) which is suitable for receiving a tyre, the wheel ( 14 ) carrying a sensor ( 60 ) for measuring the pressure in the tyre; a spindle ( 12 ) about which the wheel ( 14 ) is rotatably mounted by means of bearings ( 22 ); and means ( 70 ) of communication between the sensor ( 60 ) and means ( 86 ), associated with the spindle, for using the measurements carried out by the sensor ( 60 ), characterized in that the communication means ( 70 ) are suitable for radiofrequency transmission at a frequency higher than 50 kHz and comprise a rotating antenna ( 74 ) carried by the wheel ( 14 ) and a fixed antenna ( 78 ) carried by the spindle ( 12 ), the two antennae ( 74 , 78 ) not having their own means of guidance in rotation, and in that the rotating antenna ( 74 ) and the fixed antenna ( 78 ) are generally annular and are located in the same plane in a concentric manner about the axis (X-X) of rotation of the wheel ( 14 ), the average radial distance between the rotating antenna ( 74 ) and the fixed antenna ( 78 ) exceeding 2 mm.
