Abstract

An improved vehicle sway control assembly designed to limit excessive side swaying of an axle of a vehicle during all driving conditions. The system utilizes two frame brackets (77), (97), one axle/spring bracket (129), and two rods (35), (67). The first rod (35) has one end attached to a frame bracket (77) and the other end to the axle/spring bracket (129). It incorporates a telescoping feature allowing the rod end nearest the frame bracket (77) to telescope. The second rod (67) is attached on the opposite side to a frame bracket (97) on one end and a mid section plate (34) on the telescoping rod (35) on the other end. The counter rotational arch of the second rod (67) will force the telescoping rod (35) to extend thus canceling the telescoping rod (35) arch curve travel if it were a solid rod. The overall design will limit axle (166) to frame (78) side movement while providing near straight vertical axle (166) travel.

Claims

1. A sway control apparatus comprising:

a sway control rod assembly comprising a sway control rod having a telescoping section disposed proximate a distal end thereof, a first and second rotating bearing-type attachment device disposed on opposite ends thereof, and including a mounting plate disposed proximate a medial portion thereof, said mounting plate adapted to connect to a third rotating bearing-type attachment device, said sway control rod assembly attached by said first rotating bearing type attachment device at a proximal end to an axle spring assembly of a vehicle and to a frame of said vehicle by said second rotating bearing attachment device at a distal end thereof; and

a vertical control rod assembly having a third and a fourth rotating bearing-type attachment devices on opposite ends thereof with said fourth rotating bearing type device attached to said frame of said vehicle, and said fourth rotating bearing type attachment device attached to said mounting plate of said sway control rod assembly.

2. A vehicle sway control assembly comprising:

a first rod; and

a second rod, said second rod rotatably connected to said first rod proximate a medial portion of said first rod.

3. The vehicle sway control assembly of claim 2, wherein said second rod is offset from said first rod a distance along an axis of rotation thereof such that said second rod is capable of rotating through a zero degree angle relative to said first rod.

4. The vehicle sway control assembly of claim 2, further including a torque control assembly, said torque control assembly preventing rotation of said first rod about a longitudinal axis thereof.

5. The vehicle sway control assembly of claim 4, wherein said torque control assembly prevents rotation of said first rod about said longitudinal axis thereof by counteracting a torque applied to said first rod by said second rod due to said offset.

6. The vehicle sway control assembly of claim 2, wherein a first end of said first rod is rotatably attached to a suspension element of a vehicle and a second end of said first rod is rotatably attached to a first portion of a frame carried by said vehicle, and wherein a length of said first rod is adjustable, said length being a distance between an attachment point with said suspension element and an attachment point with said first portion of said frame.

7. The vehicle sway control assembly of claim 6, wherein a second end of said second rod is rotatably connected to a second portion of said frame, said second portion of said frame being spaced from said first portion of said frame.

8. The vehicle sway control assembly of claim 7, wherein vertical travel of said suspension element causes a change in a length of said first rod, whereby said vertical travel of said suspension element does not cause a substantial lateral movement of said frame.

9. The vehicle sway control assembly of claim 2, wherein a length from a first connection point to a second connection point is fixed, said first connection point being a connection point of said second rod to said second portion of said frame and said second connection point being a connection point of said first end of said second rod to said first rod, and wherein a length from a third connection point to said second connection point is fixed, said third connection point being a connection point of said first end of said first rod to said suspension element of said vehicle.

10. The vehicle sway control assembly of claim 6, wherein said first rod further comprises a telescoping section, and wherein said length of said first rod is adjustable due to a telescoping movement of said telescoping section.

11. The vehicle sway control assembly of claim 2, wherein at least one of said first end of said second rod and said medial portion of said first rod further comprises a rotating bearing type attachment device connecting said second rod to said first rod.

12. The vehicle sway control assembly of claim 6, further comprising at least one bushing and washer assembly, said bushing and washer assembly preventing rotation of said first bar about a longitudinal axis thereof.

13. The vehicle sway control assembly of claim 7, further comprising a plurality of brackets configured to enable said motor vehicle sway control assembly to be operably connected to said suspension element, said first portion of said frame, and said second portion of said frame.

14. The vehicle sway control assembly of claim 6, wherein said suspension element is selected from the group consisting of a front suspension element, a rear suspension element, a coil spring suspension element, a leaf spring suspension element, and an air suspension element.

15. The vehicle sway control assembly of claim 7, wherein said second portion of said frame is one of in front of a connection point between said first rod and said suspension element and in back of a connection point between said first rod and said suspension element.

16. The vehicle sway control assembly of claim 2, wherein said first rod further comprises a first connection point on a first end thereof and a second connection point on a second end thereof, said first connection point and said second connection point being adapted to attach to at least one of a vehicle suspension element, a vehicle frame, a vehicle suspension mounting bracket, and a frame mounting bracket.

17. The vehicle sway control assembly of claim 2, wherein said first rod includes a length from a first end thereof to a second end thereof, said length being adjustable.

18. The vehicle sway control assembly of claim 17, wherein a length of said first rod between a first end thereof and said medial portion is fixed.

19. The vehicle sway control assembly of claim 9, wherein vertical travel of said suspension element causes a change in a length of said first rod, whereby said vertical travel of said suspension element does not cause a substantial lateral movement of said frame.
