Abstract

Embodiments of the present invention describe a recreational vehicle spindle, including a spindle body having one or more sockets in the spindle body, and an upper attachment mechanism in contact with the spindle body and adapted to attach to a steering component. The spindle also includes a lower attachment mechanism in contact with the spindle body and adapted to attach to a ski or wheel. The one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.

First claim

What is claimed is:

1. A recreational vehicle spindle, comprising:
a spindle body, having one or more sockets in the spindle body, each socket including an inner wall and an outer wall,
an upper attachment mechanism in contact with the spindle body, adapted to attach to a steering component; and
a lower attachment mechanism in contact with the spindle body, adapted to attach to a ski or wheel;
wherein the one or more sockets are adapted to each receive a ball and stud forming one or more ball joints.

2. The spindle of claim 1 , wherein the spindle body comprises a first socket and a second socket.

3. The spindle of claim 1 , further comprising a protrusion of the spindle body for positioning of the upper attachment mechanism.

4. The spindle of claim 1 , wherein the one or more sockets are positioned in an upper portion of the spindle body.

5. The spindle of claim 1 , wherein the one or more sockets are positioned in both a mid portion and upper portion of the spindle body.

6. A recreational vehicle suspension system, comprising:
one or more spindle bodies; each body including:
one or more sockets in the spindle body, each socket including an inner wall and an outer wall,
an upper attachment mechanism in contact with the spindle body, attached to one or more steering components; and
a lower attachment mechanism in contact with each spindle body, attached to a ski or wheel;

one or more connecting arms, each connecting arm attached to a stud and ball at a distal end, forming a ball joint with each socket of the spindle body; and
one or more dampening components, in contact with one or more of the connecting arms and spindle body at a distal end.

7. The system of claim 6 , wherein the stud comprises a distal portion of the one or more connecting arms.

8. The system of claim 6 , wherein the one or more connecting arms comprise A-arm suspension arms.

9. The system of claim 6 , wherein the one or more connecting arms comprise an upper connecting arm and lower connecting arm.

10. The system of claim 6 , wherein the lower attachment mechanism comprises a pivot pin, adapted to allow the ski or wheel to pivot in one or more directions.

11. A recreational vehicle, comprising:
one or more spindle bodies; each body including:
one or more sockets in the spindle body, each socket including an inner wall and an outer wall,
an upper attachment mechanism in contact with the spindle body, attached to one or more steering components; and
a lower attachment mechanism in contact with each spindle body, attached to a ski or wheel;

one or more connecting arms, each connecting arm in contact with a stud and ball at a distal end, forming a ball joint with each socket of the spindle body, and attached to a chassis at the proximal end;
one or more dampening components, in contact with one or more of the connecting arms and spindle body at a distal end and attached to the chassis at a proximal end;
an engine, mounted on the chassis;
a drive track, in contact with the chassis;
a drive train, operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track; and
a rear suspension system, in contact with at least the chassis and drive track.

12. The vehicle of claim 11 , wherein the stud comprises a distal portion of the one or more connecting arms.

13. A snowmobile comprising:
a chassis;
a rear suspension coupled to the chassis;
an endless track;
a front suspension coupled to the chassis; the front suspension comprising:
an upper a-arm and a lower a-arm;
a dampening member attached to at least one of the upper a-arm and lower a-arm;

a ski; and
a front spindle, the front spindle having a spindle body, the spindle body having at least two sockets formed therein; at least one of the at least two sockets having therein a ball, the ball attached to a stud, the stud extending from the ball; wherein at least one of the upper a-arm and the lower a-arm are attached to the stud and wherein the socket has a polymeric material disposed between the ball and the socket.

14. The snowmobile of claim 13 , wherein the dampening member comprises one or more of a shock and coil spring.
