Tyre pressure regulating assembly and turning duct for same

摘要

The system has a pressure sensor (15) as a part of a pressure sensor unit (14) and attached to a rotatably supported wheel (5), which carries a tire (7). A contact-less power transmission device (20) is attached to a rotary feed-through (1) for transmitting electrical energy, required for operation of the sensor, to the sensor. The power transmission device has an antenna pair comprising stator-side and rotor-side antennas arranged opposite to each other relative to an active gap, which separates a rotor (3) from a stator (2).
