Conductorless amp; contactless transmission unit for electrical signals and power into rotation applications

摘要

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