The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A link arm for restraining lateral movement of a pivotable vehicle suspension system, wherein a first end of the link arm is pivotally connected to a wheel-mounting end of the system and a second end of the link arm is pivotally mounted to a frame of the vehicle such that the link arm may pivot relative to the frame in unison with the wheel-mounting end and restrain lateral movement of the system relative to the frame.
2. The link arm of claim 1, wherein when viewed in plan, the link arm comprises a pair of linear regions spaced apart by a bend or arcuate region.
3. The link arm of claim 1, wherein the second end of the link arm comprises a ball and socket joint enabling pivoting of the link arm relative to the frame about more than one axis.
4. A method for restraining lateral movement of a pivotable vehicle suspension system using a link arm, said method comprising the steps of:
pivotally connecting a first end of the link arm to a wheel-mounting end of the system; and
pivotally mounting a second end of the link arm to a frame of the vehicle such that the link arm may pivot relative to the frame in unison with the wheel-mounting end and restrain lateral movement of the system relative to the frame.
5. The method of claim 4, wherein when viewed in plan, the link arm comprises a pair of linear regions spaced apart by a bend or arcuate region.
6. The method of claim 4, wherein the second end of the link arm comprises a ball and socket joint enabling pivoting of the link arm relative to the frame about more than one axis.
7. A vehicle suspension system comprising:
a control arm assembly comprising a frame-mounting end pivotally mountable to a frame of a vehicle and a wheel-mounting end mountable to a wheel of the vehicle, wherein the wheel-mounting end is pivotable between raised and lowered positions relative to the frame and biased to remain in the lowered position;
a shock absorber extending between the frame and the control arm assembly; and
a link arm extending laterally of the control arm assembly to the frame, wherein a first end of the link arm is pivotally connected to the wheel-mounting end and a second end of the link arm is pivotally mountable to the frame such that the link arm may pivot relative to the frame in unison with the wheel-mounting end and restrain lateral movement of the wheel-mounting end relative to the frame.
8. The vehicle suspension system of claim 7, wherein when viewed in plan, the link arm comprises a pair of linear regions spaced apart by a bend or arcuate region.
9. The vehicle suspension system of claim 7, wherein the second end of the link arm comprises a ball and socket joint enabling pivoting of the link arm relative to the frame about more than one axis.
10. A vehicle suspension system comprising:
a control arm mount connectable to a frame of the vehicle;
a control arm assembly comprising a frame-mounting end pivotally connected to the control arm mount and a wheel-mounting end mountable to a wheel of the vehicle, wherein the wheel-mounting end is pivotable between raised and lowered positions relative to the frame;
a shock absorber extending between the ends, wherein an upper end of the shock absorber is mountable to the frame and a lower end of the shock absorber is pivotally connected to the wheel-mounting end;
a biasing member extendable between the control arm assembly and the frame, for biasing the wheel-mounting end into the lowered position; and
a link assembly comprising a link mount connectable to the frame and a link arm extending laterally of the control arm assembly to the link mount, wherein a first end of the link arm is pivotally connected to the wheel-mounting end and a second end of the link arm is pivotally connected to the link mount such that the link arm may pivot relative to the frame in unison with the wheel-mounting end and restrain lateral movement of the wheel-mounting end relative to the frame.
11. The vehicle suspension system of claim 10, wherein the link arm extends laterally of the control arm assembly and forwardly to the link mount.
12. The vehicle suspension system of claim 10, wherein when viewed in plan, the link arm comprises a pair of linear regions spaced apart by a bend or arcuate region.
13. The vehicle suspension system of claim 10, wherein the second end of the link arm comprises a ball and socket joint enabling pivoting of the link arm relative to the link mount about more than one axis.
