A toy vehicle and track assembly includes a vehicle and a track along which the vehicle travels. The vehicle is formed with a plurality of wheels and a motor adapted to drive the wheels upon actuation. The track is formed with a guide extending along the length of the track. First and second clips are mounted for pivotal movement on the underside of the vehicle. The clips are adapted to engage the guide and to cooperate to move the vehicle towards the track such that at least one of the wheels is always in driving contact with the track.

1. Apparatus including in combination a vehicle formed with a plurality of wheels and a motor adapted to drive said wheels upon actuation, a track along which said vehicle travels, said track formed with a guide extending the length of said track, a first clip mounted for pivotal movement to the underside of said vehicle, said first clip adapted to engage said guide, a second clip mounted for pivotal movement to the underside of said vehicle, said second clip adapted to engage said guide, said first and second clips cooperating to guide said vehicle along said track and positioned on said vehicle so as to maintain said vehicle moving on said track by pivoting said vehicle with respect to said track such that one end of said vehicle is urged towards said track and at least one of said wheels is always in driving contact with the track. 2. Apparatus as in claim 1 in which said second clip is shorter in length than said first clip and said clips are mounted to the underside of said vehicle at a common location. 3. Apparatus as in claim 2 in which said common location is closer to the rear end of the vehicle than the front end. 4. Apparatus as in claim 3 in which said clips are biased so as to pull the vehicle toward the track. 5. Apparatus as in claim 4 in which the biasing force on said second clip is greater than the biasing force on said first clip. 6. Apparatus as in claim 5 in which said biasing force is provided by a spring. 7. Apparatus including in combination a vehicle formed with a plurality of wheels and a motor adapted to drive said wheels upon actuation, a track along which said vehicle travels, said track formed with a guide extending the length of said track, at least one clip mounted for pivotal movement to the underside of said vehicle and extending towards one end of said vehicle, said clip adapted to engage said guide, means biasing said clip so as to pull said clip toward the vehicle, said clip and said biasing means cooperating to guide said vehicle along said track and positioned on said vehicle so as to maintain said vehicle moving on said track by pivoting said vehicle with respect to said track such that one end of said vehicle is urged towards said track and at least one of said wheels is always in driving contact with the track. 8. Apparatus as in claim 7 in which said guide is formed from a horizontal portion and a vertical portion, said vertical portion extending from said track and terminating in said horizontal portion to form a guide with a T-shaped cross section. 9. Apparatus as in claim 8 in which said clip engages the opposite sides of said vertical portion to guide said vehicle along said track and the underside of said horizontal portion to keep said vehicle on said track. 10. Apparatus as in claim 9 in which said clip is mounted to the underside of said vehicle at a point which is closer to the rear end of said vehicle than the front end and the clip extends toward the rear of said vehicle. 11. Apparatus including in combination a vehicle formed with a pair of front wheels and a pair of rear wheels and a motor adapted to drive said wheels upon actuation, a track along which said vehicle travels, said track formed with a guide extending the length of said track, a first clip mounted for pivotal movement to the underside of said vehicle, said first clip extending towards said front wheels and adapted to engage said guide, a second clip mounted for pivotal movement to the underside of said vehicle, said second clip extending towards said rear wheels and adapted to engage said guide, said clips mounted to the underside of said vehicle at a common location located closer to the rear end of the vehicle than the front, and said first clip being longer in length than said second clip, means biasing said first and second clips so as to pull said clips to said vehicle, said biasing means and said clips cooperating to move said vehicle towards said track such that at least one of said wheels is always in driving contact with said track. 12. Apparatus as in claim 11 in which the biasing force on said second clip is greater than the biasing force on said first clip. 13. Apparatus as in claim 11 in which said track is formed with a pair of wheel paths which extend along the length of the track on opposite sides of said guide, said wheel paths formed so as to have a relatively high coefficient of friction so as to prevent wheel spin and said guide formed so as to have a relatively low coefficient of friction. 14. Apparatus including in combination a vehicle formed with a front and back, a plurality of wheels and a motor adapted to drive said wheels upon actuation, a track along which said vehicle travels, said track formed with a guide extending the length of said track, a first clip mounted for pivotal movement to the underside of said vehicle and extending towards the front of said vehicle, said first clip adapted to engage said guide at a location proximate to said front of said vehicle, a second clip mounted for pivotal movement to the underside of said vehicle and extending towards the rear side of said vehicle, said second clip adapted to engage said guide at a location proximate said rear of said vehicle, said first and second clips cooperating to guide said vehicle along said track and positioned on said vehicle so as to maintain said vehicle moving on said track by pivoting said vehicle with respect to said track such that one end of said vehicle is urged towards said track and at least one of said wheels is always in driving contact with the track. 15. Apparatus as in claim 14 in which said second clip is shorter in length than said first clip and said clips are mounted to the underside of said vehicle at a common location. 16. Apparatus as in claim 15 in which said common location is closer to the rear end of the vehicle than the front end. 17. Apparatus as in claim 16 in which said clips are biased so as to pull the vehicle toward the track. 18. Apparatus as in claim 17 in which the biasing force on said second clip is greater than the biasing force on said first clip. 19. Apparatus as in claim 18 in which said biasing force is provided by a spring.
