Abstract

Dual, diagonal bars to reduce vehicle roll and pitch rates, thereby stabilizing the vehicle, are disclosed. One bar attaches linking the left front suspension to the right rear suspension, and the other bar links the right front suspension and the left rear suspension. Attachment points link alternate corners rather than being on the same axle. The bars are attached to the suspension with additional attachment to either the suspension or the chassis. The primary means of mounting, or attaching, the bars is in at least four spots for each bar. There may be a need to add one additional mount, or more, per bar along the long section of the bar between the front and rear chassis mounts to control flex and provide a more pleasant ride. The opposing end of the bar is attached to the rear suspension outboard near the spring mount on a live rear axle, or on the control arm of an independent rear suspension. A sleeve could replace the two mounts that are on the suspension. An alternate method of mounting the bars is to have the bars effectively mounted in two places along each suspension arm, thereby causing the bar to act as a torsion bar.

Claims

1. An improved vehicle having a chassis, the improved vehicle, comprising in combination:

a left front suspension;

a right front suspension;

a left rear suspension;

a right rear suspension;

a first bar linking the left front suspension to the right rear suspension; and

a second bar linking the right front suspension to the left rear suspension.

2. An improved vehicle according to claim 1 wherein there is clearance between the first bar and the second bar whereby the two bars do not touch each other.

3. An improved vehicle according to claim 2 further comprising:

a first front mount to locate the first bar on the chassis near the front of

the first bar wherein the first bar can pivot freely;

a first rear mount to locate the first bar on the chassis near the rear of the

first bar wherein the first bar can pivot freely;

a second front mount to locate the second bar on the chassis near the front

of the second bar wherein the second bar can pivot freely; and

a second rear mount to locate the second bar on the chassis near the rear

of the second bar wherein the second bar can pivot freely.

4. An improved vehicle according to claim 3 wherein the first bar forms a torsion section, a front lever arm, and a rear lever arm and the second bar forms a torsion section, a front lever arm, and a rear lever arm.

5. An improved vehicle according to claim 2 wherein the first bar forms a torsion section, a rear lever arm and a front lever arm and the second bar forms a torsion section, a rear lever arm and a front lever arm, further including:

a front left locator mount attached to the front left suspension to locate the front lever arm of the first bar;

a front right locator mount attached to the front right suspension to locate the front lever arm of the second bar;

a rear left locator mount attached to the rear left suspension to locate the rear lever arm of the second bar; and

a rear right locator mount attached to the rear right suspension to locate the rear lever arm of the first bar.
