Model car racing track

Abstract

A model car racetrack with at least one model car which is guided along a lane, a roadway which defines the lane, wherein the roadway has at least one bus bar which extends in the direction of the lane, and a transformer arrangement comprising a primary element and a secondary element for contact-free energy transmission from the roadway to the model car, wherein the bus bar is the primary element of the transformer arrangement and the model car represents the secondary element of the transformer arrangement for coupling in the electromagnetic field which is produced by the primary element.

Thus, having described the invention, what is claimed is: 
     
         1 . A model car racing track having at least one model car guided along a lane and a track defining the lane, wherein the track has at least one bus_bar extending in the direction of the lane, including a transformer arrangement with a primary element and a secondary element for contact-free and interruption-free transmission of energy and control signals from the track to the model car, wherein the bus_bar is arranged on a surface of the track and is the primary element of the transformer arrangement extending in the direction of the lane, and the model car comprises the secondary element of the transformer arrangement for coupling in the electromagnetic field generated by the primary element, wherein the secondary element has a winding or a plurality of windings, wherein the winding or plurality of windings defines a screw vector (S) extending horizontally in a width direction Y which extends substantially at right angles to the direction of the lane. 
     
     
         2 . The model car racing track of  claim 1 , wherein a rotation vector (R) of the electromagnetic field generated by the primary element points substantially in the direction of the lane. 
     
     
         3 . The model car racing track of  claim 1 , wherein the secondary element has a main direction of extension (H) which is substantially at right angles to the direction of the lane. 
     
     
         4 . (canceled) 
     
     
         5 . The model car racing track of  claim 1 , wherein at least one second lane with at least one second bus_bar is provided, along which a second model car is guided along the lane, wherein an electrical current with a first frequency is applied to the first bus_bar and a second electrical current with a second frequency is applied to the second bus_bar, wherein the first frequency is different from the second frequency. 
     
     
         6 . The model car racing track of  claim 5 , wherein the second frequency is at least one and a half times the first frequency. 
     
     
         7 . The model car racing track of  claim 5 , wherein the first frequency is 400 kHz and the second frequency 600 kHz. 
     
     
         8 . The model car racing track of  claim 1 , wherein the at least one lane has two parallel bus_bars extending in the direction of the lane. 
     
     
         9 . The model car racing track of  claim 8 , wherein the two bus_bars of a lane are wired electrically in parallel. 
     
     
         10 . The model car racing track of  claim 8 , wherein the two bus_bars of a lane are wired electrically in series. 
     
     
         11 . The model car racing track of  claim 7 , wherein the at least one lane has two parallel bus bars extending in the direction of the lane. 
     
     
         12 . The model car racing track of  claim 11 , wherein the two bus bars of a lane are wired electrically in parallel. 
     
     
         13 . The model car racing track of  claim 11 , wherein the two bus bars of a lane are wired electrically in series.
