1. A toy vehicle comprising:
- a drive motor fitted with a drive shaft and a driven axle equipped with wheels; and
a transmission unit between the drive shaft and the driven axle, the transmission unit including first and second gears of different transmission ratios, the first gear being associated with a first direction of rotation of the drive motor, and the second gear being associated with a second direction of rotation of the drive motor that is opposite the first direction of rotation,wherein the transmission unit comprises;
a first pinion non-rotatably affixed to the drive shaft, anda cage rotatably coupled to the drive shaft, the cage keeping a second pinion engaged with the first pinion and jointly with the second pinion being pivotable about the shaft and forming a pivoting axis between two end positions,the first gear being non-rotatably joined to the driven axle, the first and second gears having different numbers of teeth and being configured so that in a first end position of the cage, the second pinion meshes with the first gear and, in a second end position of the cage, the second pinion meshes with the second gear.

6. A toy vehicle for track-guided motor racing tracks, comprising:
-
a drive motor having a drive shaft; a driven axle having wheels; and a gearbox disposed between the drive shaft and the driven axle, said gearbox being arranged to change the speed of the driven axle, without changing the direction of rotation of the driven axle, in response to changing the rotation direction of the drive motor, the gearbox including a first gear arranged to be coupled between the drive shaft and the driven axle with a first gear ratio in response to a first rotation direction of the drive motor and a second gear arranged to be coupled between the drive shaft and the driven axle with a second gear ratio in response to a second rotation direction in opposition to the first rotation direction of the drive motor. - View Dependent Claims (7, 8)

9. A toy vehicle comprising:
-
a drive motor having a drive shaft; a driven axle having wheels; and a gearbox disposed between the drive shaft and the driven axle, said gearbox being arranged to change the speed of the driven axle, in response to changing the rotation direction of the drive motor, the gearbox including a first gear arranged to be responsive to a first rotation direction of the drive motor and a second gear arranged to be responsive to a second rotation direction in opposition to the first rotation direction of the drive motor. said gearbox comprising; a first pinion non-rotatably linked to the drive shaft; a cage rotatably linked to the drive shaft, said cage holding a second pinion in engagement with the first pinion and, together with the second pinion, being rotatable about the drive shaft as a pivot axis between two end positions; and a first toothed gear non-rotatably fixed to the driven axle and a second toothed gear non-rotatably fixed to the driven axle, said first and second toothed gears having different numbers of teeth and being arranged such that in a first end position of the cage, the second pinion meshes with the first toothed gear, and in a second end position of the cage, the second pinion meshes with the second toothed gear. - View Dependent Claims (10, 11)
