Abstract

An improved vehicle sway control assembly designed to limit excessive side swaying of front engine rear axle driven motor vehicles 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 motor vehicle sway control assembly for suspension systems for reducing unwanted frame to rear axle/spring assembly side to side swaying during all driving conditions, said motor vehicle sway control assembly comprising:

a. a rear axle/spring attachment bracket designed to attach to said rear axle/spring assembly on a first side of a vehicle configured to accept attachment of a rotating bearing type attachment device;

b. a first frame attachment bracket designed to attach to a frame of said vehicle on an opposing side thereof from said rear axle/spring assembly, said first frame attachment bracket configured to accept attachment of a rotating bearing type attachment device;

c. a sway control rod with a first rotating bearing type attachment device on a first end thereof and a second rotating bearing type attachment device on a second end thereof, and with a mounting plate connected to a mid section thereof, said mounting plate configured to accept attachment of a rotating bearing type attachment device, said sway control rod assembly comprising a telescoping section proximate said second end, said telescoping section with said second rotating bearing type attachment device attached to said first frame attachment bracket, said first rotating bearing type attachment device attached to said rear axle/spring attachment bracket;

d. second frame attachment bracket designed to attach to said frame proximate rear axle/spring attachment bracket, and designed to accept attachment of a rotating bearing type attachment device; and

e. a vertical control rod assembly having a third rotating bearing type attachment device on a first end thereof and a fourth rotating bearing type attachment device on a second end thereof, wherein said third rotating bearing type attachment device is attached to said second frame attachment bracket and said fourth rotating bearing type attachment device is attached to said mounting plate of said sway control rod assembly;

wherein said sway control rod assembly reduces unwanted frame to rear axle/spring assembly side to side swaying.

2. The motor vehicle sway control assembly of claim 1, further comprising a torque control device operably connected to said sway control rod to prevent rotation of said sway control rod about a longitudinal axis thereof.
