Abstract

A model vehicle chassis has a main body and a front right suspension connected with the main body. The front right suspension has a lower suspension arm which includes a frontward piece and a mating rearward piece. Both the frontward and rearward pieces include frontward and rearward left connecting arms which extend toward and are connected with the main body. The frontward left connecting arm has a first cup and the rearward left connecting arm has a second cup. A shaft is connected with a front right lower portion of the main body. A pin runs through the shaft so that the forward and rearward ends of the pin extend through opposing ends of the shaft and engages the first and second cups, respectively.

Claims

1. A lower suspension arm of a model vehicle chassis comprising:

a frontward piece;

a rearward piece which mates with the frontward piece, wherein both the frontward and rearward pieces include frontward and rearward connecting arms which extend toward and are connected with a main body of the model vehicle chassis, and wherein the frontward connecting arm has a first cup and the rearward connecting arm has a second cup;

a shaft formed through a front right lower portion of the main body; and

a pin having forward and rearward ends which extend through opposing ends of the shaft and which are engaged by the first and second cups, respectively.

2. The model vehicle chassis of claim 1, wherein the front right suspension further comprises a C-hub connected with the lower suspension arm.

3. The model vehicle chassis of claim 2, wherein the C-hub forms a first protrusion extending in a forward direction, and a second protrusion opposed to the first protrusion and extending in a rearward direction, wherein the first and second protrusions are movably connected with the lower suspension arm.

4. The model vehicle chassis of claim 3, wherein both the frontward and rearward pieces of the lower suspension arm include frontward and rearward right connecting arms which extend toward and are connected with the first and second protrusions, respectively.

5. The model vehicle chassis of claim 4, wherein the frontward right connecting arm has a third cup and the rearward right connecting arm has a fourth cup, and wherein the first and second protrusions of the C-hub engage the third and fourth cups, respectively.

6. The model vehicle chassis of claim 3, wherein the first and second protrusions are integrally formed as one piece with the C-hub.

7. A model vehicle chassis comprising:

a universal drive shaft connected to a main body of the model vehicle chassis at a first end and a first engagement member at a second end; and

a wheel having a rim surrounded by a tire, the wheel forming a second engagement member on an inner surface of the rim which mates with the first engagement member.

8. The model vehicle chassis of claim 7, wherein the wheel is secured to the universal drive shaft using no more than one fastener.

9. The model vehicle chassis of claim 8, wherein the fastener is a screw.

10. A front suspension of a model vehicle chassis comprising:

a C-hub;

upper and lower suspension arms connected with a main body of the model vehicle chassis at first ends and with the C-hub at second ends; and

a steering knuckle forming upper and lower protrusions, wherein the upper and lower protrusions are movably connected with the C-hub.

11. The model vehicle chassis of claim 10, and a universal drive shaft which passes through an opening in the C-hub, the C-hub having upper and lower slots above and below the opening, and wherein the upper and lower slots are adapted to receive the upper and lower protrusions.

12. The model vehicle chassis of claim 10, wherein the upper and lower protrusions are integrally formed as one piece with the steering knuckle.

13. The model vehicle chassis of claim 10, wherein the upper and lower protrusions are secured to the C-hub in the upper and lower slots through upper and lower connecting members.

14. The model vehicle chassis of claim 13, wherein the upper connecting member is secured to the through a pair of fasteners, while the lower connecting member is secured to the C-hub through no more than one fastener.

15. A front suspension of a model vehicle chassis comprising:

a C-hub; and

upper and lower suspension arms connected to a main body of the model vehicle chassis at first ends and to the C-hub at second ends, wherein the upper suspension arm is connected to the C-hub using a single-piece fastener.

16. The model vehicle chassis of claim 15, wherein the upper suspension arm is connected to the main body using no more than one fastener.

17. The model vehicle chassis of claim 15, wherein the fastener is a king pin.

18. A front suspension of a model vehicle chassis comprising:

a spring coil shock; and

a lower suspension arm connected at one end to a main body of the model vehicle chassis and the spring coil shock, wherein the lower suspension arm includes a frontward piece and a rearward piece which is mated with the frontward piece, wherein the frontward piece includes a ball-shaped protrusion, and wherein the spring coil shock is movably connected with the ball-shaped protrusion at a lower end of the spring coil shock.

19. The model vehicle chassis of claim 18, wherein the spring coil shock is connected with the main body at an upper end of the spring coil shock using a fastener which goes through a cylindrical sleeve connected with the spring coil shock.

20. The model vehicle chassis of claim 19, wherein the spring coil shock includes an L-shaped member connected with an upper portion of the spring coil shock, wherein the L-shaped member forms an opening, and wherein the cylindrical sleeve is positioned through the opening

21. The model vehicle chassis of claim 20, wherein the cylindrical sleeve includes a frontward portion having a first diameter connected with a rearward portion having a second diameter, wherein the second diameter is smaller than a diameter of the opening while the first diameter is larger than a diameter of the opening.

22. The model vehicle chassis of claim 18, wherein the spring coil shock has a cup at the lower end of the spring coil shock, and wherein the cup engages the ball-shaped protrusion.

23. The model vehicle chassis of claim 22, wherein the cup is snap-fit with the ball-shaped protrusion.

24. The model vehicle chassis of claim 18, wherein the ball shaped protrusion is integrally formed as one piece with the forward piece of the lower suspension arm.
