发明名称 Track-guided toy vehicle
摘要 A toy vehicle is operated as a track-guided vehicle and cooperates with a metallic current rail device of the track via one or more current consumers. A magnet is installed in the toy vehicle which is moved by an electric motor to optimize the traction between the track and the toy vehicle. This magnet is directed at the current rail device of the track. The magnet's magnetic force can be influenced as a function of driving operation states of the toy vehicle driven by the electric motor.
