Where is torsion bar

The first is that these bars generally do not offer what is known as a progressive spring rate. In suspensions with a progressive spring, the coils of the spring are spaced at different distances from each other.

This allows the suspension system to enable firm steering, braking and handling, while also providing for a smooth and comfortable ride. Torsion bar suspension systems were once relatively common in passenger vehicles, but today are used primarily for the suspension systems of trucks and sport utility vehicles SUVs.

Some notable automobiles that used this type of suspension were the original Volkswagen Beetle , Porsche , Porsche models that utilized an air-cooled engine, and much of the Chrysler line-up of cars from the late s through the late s.

This is done by using the adjuster bolt located at the frame end of the torsion bar. The weight placed on the control arm of the torsion bar in unchanged when this adjustment is made. Once the torsion bar is manipulated in this manner, rides in the vehicle may feel somewhat stiffer. This is due to the new angle of the control arm.

It is also a possibility that the adjuster bolts may have been wound too far. This causes a lack of room between the control arm of the vehicle and the upper portion of the torsion bar closest to the under side of the vehicle. After making a change to the height of the torsion bar, it is a good idea to have the alignment of your vehicle checked to make the sure the weight of the vehicle body is properly distributed.

Both cars and trucks have torsion bar suspensions. They provide the suspension coil springs, and leaf springs offer with the added benefit of ride height adjustability. They can be designed longitudinally of transversely.

Weak torsion bars or worn anchors and bushings alter the vehicle's ride height, affecting stability and causing tire wear. A typical longitudinally designed torsion bar is a long steel bar fitted between the frame of the vehicle and one of the control arms. It may be the upper or lower control arm, usually the lower. Located at the frame end of the torsion bar is an adjuster or key. These are sometimes referred to as hex keys are used to apply the twisting motion needed for vehicle suspension and adjustment.
