Patent ID: 8758079

Claim:
A toy motorcycle for use on a track with a guide groove, comprising: an electric motor; a chassis; a support structure located at a bottom of the chassis that includes at least two support wheels and a magnet; a guide configured to engage a guide groove of a track, the guide being joined to the support structure; a frame associated with the chassis; a rear traction wheel mounted on the frame and operatively coupled to the electric motor; and a tilting system that tilts the frame and the rear traction wheel relative to the support structure as the motorcycle moves along curved portions of a track such that the rear traction wheel traces a trajectory around curved portions of the track that is different from a trajectory of the guide groove in the track, the tilting system comprising: a first rack that is integral with the guide, at least one toothed wheel that meshes with the first rack, a second rack that also meshes with the toothed wheel and which is integral with the frame, a pair of strips that confine the first and second racks and the toothed wheel, a first rotational axis located on the first rack, and a second rotational axis located on the second rack, wherein when the toy motorcycle traverses a curved section of a track, centripetal forces acting on the frame cause the at least one toothed wheel to move with respect to the first rack, and thereby rotate, and wherein rotation of the at least one toothed wheel causes the second rack and the frame to rotate around the second rotational axis of the second rack.
