How does a torsion bar work on a car?
One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar’s torsion resistance.
How to replace a torsion bar adjustment bolt?
Apply paint (spray paint or a paint stick) to the threads on the torsion bar adjustment bolt. The purpose is to allow you to reset the bolt later, after you install the new suspension components, back to where it was before you loosened it. Loosen the adjustment bolt until there is no tension left on the bolt. 2.
How to replace the lower control arm of a car?
Use a paint marker to note where the torsion bar aligns with the center point of the lower control arm. Remove the front and rear nuts and bolts that hold the lower control arm to the chassis of the car. Wiggle out the lower control arm from the chassis mounting points.
When did Dodge stop using torsion bar suspension?
A reengineered torsion bar suspension, introduced with the 1976 Dodge Aspen, introduced transverse-mounted torsion bars (possibly based on the Volkswagen Type 3 passenger car) until production ended in 1989 (with Chrysler’s M platform). Some generations of the Dodge Dakota and Durango used torsion bars on the front suspension.
One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar’s torsion resistance.
What makes a beam torsion arm suspension work?
This durable design makes it work very well for off-roading because of its travel shape being an arc. The basic principle of the Beam – Torsion arm suspension is to have two parallel tubes running a few inches apart.
How are open and closed beams Treated in torsion?
In this section, open beams are treated first and closed beams are treated second. Closed beams are those with hollow sections, and other beams are called open beams. Since plane sections remain plane for round beams in torsion, the end constraint of such a beam does not effect its behavior.
How is the spring rate of a torsion bar determined?
Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar’s torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape and material.
