What is an anti roll bar and what does it do?
An anti-roll bar is a piece of tubular metal, curved in a very broad U-shape, that connects the suspension on one side of an axle to the other through the use of link rods, also known as end links.
How can I adjust the stiffness of my anti roll bar?
Another way to adjust the stiffness of an anti-roll bar is to change the thickness of the torsion bar section. In some motorsport applications, this is kept as a straight bar that locates in the drop links via square pegs or with a gear type location.
Why does my car have a soft front anti roll bar?
Alternatively, if a car has stiff rear anti-roll bar and a soft front anti-roll bar then the car will tend to oversteer during cornering. This key effect of an anti-roll bar is very important to understand when tuning a car on track and adjusting a vehicle based upon driver feedback.
How are drop links attached to roll bars?
One end of the roll bar (where the drop link mounts) needs to then be held in a fixed position, unable to move. Then the other end (where the other drop link mounts) needs to have a known force applied to it in a perfectly perpendicular direction. The amount the cantilever moves up or down needs to be measured with great accuracy.
What happens when anti roll bars are removed?
An SUV, with anti roll bars removed, shows how one wheel can be much lower than the opposite side, as the body rolls (tilts) more without anti roll bars. Photo of 2 front-wheel springs, with the tires removed. Each suspension spring is connected to the central sway bar assembly. File highlighted to show anti-roll bar.
How does an anti roll bar affect understeer?
Increasing the proportion of roll stiffness at the rear axle has the opposite effect and decreases understeer. Because an anti-roll bar connects wheels on opposite sides of the vehicle, the bar transmits the force of a bump on one wheel to the opposite wheel.
Can a rear sway bar eliminate body roll?
Adding a rear sway bar to your vehicle is one of the quickest and most cost effect ways to eliminate body roll and improve handling. Stiffen up your rear suspension and regain control of the road. Select your vehicle make, Year, and model, to see a list of products that fit your specific vehicle. Begin by choosing the make of your vehicle below.
Where to place the anti roll bar on a car?
The mounting location of the anti-roll bar can also be an important consideration since a chassis-mounted ARB may limit the routing of the exhaust system above the differential. If the car is going to have full exhaust, then a housing-mounted ARB would be a good option since it offers the space above the differential housing.
