    • The invention relates to a transmission system for motor vehicles for transmitting signals concerning tire state quantities from a wheel to an electronic evaluation or control unit mounted in the area of the vehicle body, these tire state quantities being able to be recorded, in particular, by one or more sensor modules (14) that are placed in a wheel mounted for rotating about a wheel hub (3). The invention is characterized in that a coupling device is integrated in the wheel hub. In order to generate a field coupling, this coupling device is comprised of a rotor (6a) and of a non-rotating stator (6b) and one or more of its field coupling elements (20, 22, 27a, 27b, 29a, 29b, 30a, 30b, 34a, 34b, 39a, 39b, 42, 43) are opposite one another while being separated by a narrow air gap (24). An energy and/or signal coupling ensues via electrical fields and/or magnetic files and/or electromagnetic fields. The aim of the invention is to enable the rotational speed of the wheel to be determined. To this end, the rotor (6a) and/or the stator (6b) are/is subdivided into two or more sectors in the peripheral direction, the sectors having a different permeability for a rotational speed-dependent field coupling of the rotor (6a) and stator (6b).
