CONDUCTORLESS AND CONTACTLESS TRANSMISSION UNIT FOR ELECTRICAL SIGNALS AND POWER INTO ROTATION APPLICATIONS

摘要

The device for contact-free transfer of electrical signals betweencomponents rotating relative to each other, in particular in a steering wheelbetween steering column assembly and steering wheel, with an electrical circuitcarrier with signal transmission and signal reception elements, said carrier is onthe stator-side and an electrical circuit carrier with signal transmission andsignal reception elements, said support is on the rotor-side wherein the stator-side and rotor-side electrical circuit carriers are axially or radially adjacent toeach other with their signal transmission and signal reception elements, and thesignal transmission and signal reception elements of the adjacent stator-sideand rotor-side circuit carriers are positioned relative to each other and withtheir perimeter extension they are configured so that bi-directional signaltransmission is possible between stator-side circuit carrier and rotor-side circuitcarrier in any possible relative rotational position of the rotor-side circuit carrierwith respect to the stator-side circuit carrier.
