ABSTRACT:
The present invention relates to a system for transmitting tire condition variables from a transmission device mounted on a motor vehicle to an electronic evaluating or control unit arranged in the area of the vehicle body, which is detachably fastened to a motor vehicle wheel described hereinbelow for providing an electromechanical compound arrangement.Further, a transmission device is disclosed wherein tire condition variables can be detected, and wherein a coupling device is integrated into the wheel hub (3) and composed of a rotor and a non-rotating stator for producing a field coupling, and its one or more field coupling elements are arranged opposite one another, separated by a narrow air slot (24), and energy and/or signals are coupled by means of electric fields and/or magnetic fields and/or electromagnetic fields.Still further, the system contains a vehicle wheel equipped with sensors, consisting of wheel rim (1), pneumatic tire (2), and a sensor subassembly (13, 13′, 14, 15, 44) which rotates with the wheel. The wheel has a signal connection that can be connected to the transmission device.
