Toy vehicle, especially for track-guided racetracks

Abstract

A toy vehicle, in particular for track-guided racetracks, is driven by an electric motor which cooperates via a first gear wheel provided on a drive shaft, with a second gear wheel connected to an axle shaft carrying wheels, where the distance between the drive shaft of the electric motor and the axle shaft is variable for the use of different first and second gear wheels such that different transmission ratios can be implemented. In a preferred embodiment, the axle shaft is supported in offset apertures in support bearings located in a receptacle frame, and the distance between the drive shaft and the axle shaft can be varied by rotating the bearings relative to the receptacle frame.

1 . Toy vehicle for track-guided racetracks, driven by an electric motor, said electric motor cooperating via a first gear wheel provided on a drive shaft, with a second gear wheel connected to an axle shaft having wheels, wherein a distance between the drive shaft of the electric motor and the axle shaft is variable such that different transmission ratios can be implemented by using different first gear wheels and varying the distance as required to maintain the first gear wheel engaged with the second gear wheel.  
   
   
       2 . Toy vehicle as claimed in  claim 1 , wherein the axle shaft is surrounded by supporting bearings which are spaced a distance apart and which produce a change in the distance between the drive shaft and the axle shaft through changing an orientation of the support bearings in receptacles in a receptacle frame.  
   
   
       3 . Toy vehicle as claimed in  claim 2 , wherein the change is produced by rotating the supporting bearings in the receptacles by 180°.  
   
   
       4 . Toy vehicle as claimed in  claim 2 , wherein each supporting bearing has a bearing section for the axle shaft and the bearing section has an approximately rectangular shape in a plane transverse to the axle shaft, with upright bearing walls, horizontal bearing walls, and a center axle aperature in the bearing section which is offset at different distances from the opposing upright bearing walls.  
   
   
       5 . Toy vehicle as claimed in  claim 4 , wherein each receptacle has guide sections for the horizontal bearing walls and a stop for the upright bearing walls.  
   
   
       6 . Toy vehicle as claimed in  claim 2 , wherein identification markings for transmission ratios are provided on the supporting bearings.  
   
   
       7 . Toy vehicle as claimed in  claim 2 , wherein the receptacle frame receives the electric motor.  
   
   
       8 . Toy vehicle as claimed in  claim 7 , wherein the receptacle frame carries the electric motor therein such that the end walls of the electric motor are bordered by side walls of the receptacle frame.  
   
   
       9 . Toy vehicle as claimed in  claim 2 , wherein the supporting bearings of the axle shaft are held in place in the receptacles by fixation arms of an additional frame, and wherein the additional frame protrudes with a cross part into a receptacle section of the receptacle frame.  
   
   
       10 . Toy vehicle as claimed in  claim 2 , wherein the electric motor, the axle shaft with the rear wheels and the receptacle frame together form a rear axle unit which is attached to a central frame of a chassis.  
   
   
       11 . Toy vehicle as claimed in  claim 10 , wherein a plug connection is in effect between the rear axle unit and the central frame, said plug connection having a tension fork which is mounted on the receptacle frame, said tension fork engaging in a corresponding receptacle device of the central frame.  
   
   
       12 . Toy vehicle as claimed in  claim 11 , wherein the outsides of prongs of the tension fork are provided with barb-like enlargements which are supported on supporting walls of the receptacle device.  
   
   
       13 . Toy vehicle as claimed in  claim 1 , wherein the drive shaft protrudes with its first gear wheel beyond a side wall of the receptacle frame and meshes with the second gear wheel of the axle shaft.
