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). The other component (38) is electrically connected to the rotor members (28) and the signals furnished by the sensors ( 58, 69) and representing operating parameters are transmitted by inductive coupling to a pickup (68) in the component (38) lying on the side of the rim well (22) remote from the tire (14).
