How Traction Bars Work
The use of traction bars and other traction instruments have been in implementation for many years in automobiles. They are most notably described as bars that can be found bolted to the spring and sometimes the axle. Axles tend to want to rotate when under the stress of acceleration. Traction bars help solve the negatives found with this natural occurrence by indirectly stabilizing the entire structure of the axle itself through regulating the spring. This, in turn, provides a noticeable improvement in the overall traction of the axle. These components of an axle are anything but perfectly effective but serve a necessary and sometimes drastic benefit to vehicles.
Why Traction Bars Are Needed
When subjected to increased acceleration, an axle of a vehicle will begin to naturally rotate. Once this pinion gear begins to climb, the ring gear alters the pinion angularity and the overall geometrical of the suspension itself. This process tends to cause deflection of the spring. Once this spring wraps up, an alteration in the pinion angle takes place, affecting the proper function of the axle even more.
How Traction Bars Improve Traction
In order to alter the inevitable course of this process, the force caused by the rotation in the axle has to be concentrated and focused into energy that helps traction. The traction bars redirect that force from the axle, putting it through a bellcrank or rod system, centered and placed on the front spring eye. In order for this energy to positively affect traction, it must be focused and channeled into a downward force that places increased pressure on the spring's weakest point, which is the front. This increases traction by adding an increased availability of downward force to the axle, keeping the vehicle's wheels against the ground with as much force as possible. This increases friction between the tires and the ground during rotation, which in turn increases traction.
