Abstract
A transmission device for motor vehicles for transmitting signals about tire condition variables from a wheel to an electronic evaluating or control unit arranged in the area of the vehicle body, wherein the tire condition variables can be detected especially by one or a plurality of sensor subassemblies (14) which are arranged in a wheel rotatably mounted at the body above the wheel hub (3), characterized in that a coupling device is integrated into the wheel hub, which is composed of a rotor (6a) and a non-rotating stator (6b) to generate a field coupling, and whose one or more field coupling elements (20, 22, 27a, 27b, 29a, 29b, 30a, 30b, 34a, 34b, 39a, 39b, 42, 43) are opposite each other, separated by a narrow air slot (24), and an energy and/or signal coupling takes place by way of electric fields and/or magnetic fields, and/or electromagnetic fields, is meant to determine the rotational speed of the wheel. To this end, the rotor (6a) and/or the stator (6b) is subdivided in a circumferential direction into two or more sectors, with the sectors having a differing permeability for a rotational-speed-responsive field coupling of rotor (6a) and stator (6b).
