Abstract: The invention relates to a toy car with adjustable magnetic adhesion for an auto racetrack having ferromagnetic current conductors countersunk in the roadbed. The conductors are in active communication with a permanent magnet countersunk in the chassis of the toy car. The permanent magnet is shiftable in the chassis along an inclined plane in order to adjust the clearance between permanent magnet and the current conductors. According to the invention, the permanent magnet can be shifted along a ferromagnetic holding plate oriented at an angle relative to the roadway plane. The plate is received in a retaining means formed in one piece with the chassis. The underside of the retaining means contains two guide rails, along which the permanent magnet can be shifted.

Abstract: The invention relates to a method and a device for open-loop control of the speed of an electrically driven toy car on a lane-guided racetrack. By means of a hand-actuatable closed-loop control device, the speed of the toy car can be adjusted to at least two speed levels. To adjust the magnitude of the first speed level as a fraction of the second speed level, the closed-loop control device is preferably programmable so that via the open-loop control device, the speed of the toy car is adjusted between a zero position and the first speed level and, after actuation of a selection switch, the speed of the traveling toy is adjustable between the zero position and the second speed level. The invention permits the adjustment of partial speeds of a toy car on a racetrack without using a transformer.

Abstract: A mobile toy, particularly for use on car racetracks with guide rails, comprises a driving motor, a driving disk mounted on an end of the toy and driven by the driving motor, and at least one toy driving wheel in direct frictional engagement with the driving disk for driving the toy.
