Spindle and suspension system for recreational vehicles
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.
1. A snowmobile suspension system, comprising:
a spindle body including:
a socket positioned in the spindle body,
an upper attachment mechanism attached to a steering component, and
a lower attachment mechanism attached to a ski; and
a connecting arm configured to receive a stud attached to a ball at a distal end,
wherein the socket in the spindle body receives the ball and the stud to form a ball joint, and wherein the connecting arm is pivotally secured to the spindle body via the ball joint, and
wherein the ball is disposed at least partially outboard of an outboard surface of the spindle body.
2. The snowmobile suspension system of claim 1 , wherein the socket includes an inner wall and an outer wall.
3. The snowmobile suspension system of claim 1 , wherein the ball protrudes from an inboard side of the spindle body and protrudes from an outboard side of the spindle body.
4. The snowmobile suspension system of claim 3 , wherein a distal end of the ball includes an adjustment mechanism to removably secure the ball to the spindle body, wherein the adjustment mechanism is accessible from the outboard side of the spindle body.
5. The snowmobile suspension system of claim 1 , wherein the lower attachment mechanism is positioned forward of the upper attachment mechanism relative to a snowmobile.
6. The snowmobile suspension system of claim 1 , wherein the lower attachment mechanism is removably secured to the ski via a first bolt hole through the spindle body, wherein the upper attachment mechanism is removably secured to the steering component via a second bolt hole through the spindle body, and wherein the ball is removably secured to the spindle body.
7. The snowmobile suspension system of claim 1 , further comprising:
a second socket positioned within the spindle body, the second socket receiving a second ball joint, the socket and the second socket defining an axis therebetween,
wherein the lower attachment mechanism is located along the axis, and
wherein the upper attachment mechanism is vertically positioned between the socket and the second socket.
8. The snowmobile suspension system of claim 1 , wherein the spindle body include a wall portion to prevent the ball from protruding on an outboard side of the spindle body.
9. The snowmobile suspension system of claim 1 , wherein the stud includes a flat configured to mate with a wrench to tighten a nut against the stud.
10. A snowmobile, comprising:
a spindle body including:
a cavity extending entirely through the spindle body,
an upper attachment mechanism attached to a steering component, and
a lower attachment mechanism attached to a ski;
a connecting arm configured to receive a stud attached to a ball at a distal end; and
a ball retainer including a cylindrical outer portion, wherein the ball retainer retains the ball within the cylindrical outer portion, and wherein the cavity extending entirely though the spindle body receives the ball retainer therein to form a ball joint,
wherein the connecting arm is pivotally secured to the spindle body via the ball joint.
11. The snowmobile of claim 10 , wherein a pin is pressed into the ball retainer and into the spindle body to prevent a rotational movement of the ball retainer within the cavity.
12. The snowmobile of claim 11 , wherein the cavity includes a groove, the groove at least partially receiving a retaining clip, wherein the retaining clip prevents the ball from being pushed outboard through the cavity.
13. The snowmobile of claim 12 , wherein the spindle body includes a shoulder to prevent the ball retainer from being pulled inboard through the cavity.
14. The snowmobile of claim 13 , wherein the ball is removable from the spindle body via removing the retaining clip and pushing the ball outboard through the cavity.
15. The snowmobile of claim 10 , further comprising:
a dampening component in contact with the connecting arm and the spindle body;
an engine;
a drive track; and
a drive train operatively interconnecting the engine with the drive track for delivering propulsive power to the drive track.
16. The snowmobile of claim 10 , wherein the ball protrudes from an inboard side of the spindle body and protrudes from an outboard side of the spindle body.
17. The snowmobile of claim 10 , wherein a distal end of the ball includes an adjustment mechanism to removably secure the ball to the spindle body, wherein the adjustment mechanism is accessible from an outboard side of the spindle body.
18. The snowmobile of claim 10 , wherein the lower attachment mechanism is positioned forward of the upper attachment mechanism relative to the snowmobile.
19. The snowmobile of claim 10 , further comprising:
a second cavity positioned within the spindle body, the second cavity receiving a second ball joint, the cavity and the second cavity defining an axis therebetween,
wherein the lower attachment mechanism is located along the axis, and
wherein the upper attachment mechanism is vertically positioned between the cavity and the second cavity.
