发明名称 Roadway system for model vehicles with energy-independent propulsion
摘要 The invention concerns a roadway system, the system for use with model vehicles with an energy-independent propulsion as well as a steering axle, which follow a driving wire laid directly beneath the roadway by means of a magnet, wherein the roadway system comprises individual, generally two-dimensional (meaning generally long and thin in cross section) roadway segments each having multiple respective connection edges and at least one groove on their roadway side with a diameter to accommodate the driving wire. The roadway system comprises straight, curved, flexible, and special-type roadway segments.
