Abstract: An arrangement for monitoring the operating state of vehicle pneumatic tires (14) mounted on wheel rims (10) is provided with sensors (40, 42) for detecting the air pressure and the air temperature in each tire. Furthermore, it includes transmitting means comprising rim-side mounted rotor members (28) and bodywork-side mounted stator members (32) coupled thereto for transmitting the parameters detected by the sensor (40, 42) to an evaluating arrangement in the vehicle connected to the stator members. The pressure sensor (40) and the temperature sensor (42) of each tire (14) are coupled to a first transponder (44) which as reaction to an interrogation signal generated by the evaluating arrangement transmits the data supplied to it by the pressure sensor (40) and the temperature sensor (42) to the rotor members (28) of the transmitting means.

Abstract: An arrangement for monitoring operating parameters of vehicle pneumatic tires mounted on wheel rims is provided with sensors (58, 60) for selected operating parameters and with transmitting means comprising rim-side mounted rotor members (28) and bodywork-side mounted stator members (32) coupled thereto for transmitting the operating parameters detected by the sensors (58, 60) to an evaluating arrangement in the vehicle connected to the stator members (32). In an opening (20) of the wheel rim (10) in the region of the rim well (22) a measuring module (24) comprising two components (36, 38) detachably connected together is disposed. One of the components (36, 38) is mounted on the side facing the tire (14) and the other is mounted on the side of the rim well (22) remote from the tire (14). The sensors (58, 60) are mounted on one of the two components (36).
