An anti-roll stabilizing bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is available for many Indian vehicles like Mahindra (Scorpio, Xylo), Toyota (Innova, Fortuner), etc. that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. It connects opposite (left/right) wheels together through short lever arms made from High-Grade Micro-Alloyed Spring Steel. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction.
An anti-roll stabilizing bar is usually a torsion spring that resists body roll motions. It is usually constructed out of a heavy-duty cylindrical spring steel bar, that connects to the body at two points, and at the left and right sides of the suspension. Each end of the bar is connected to an end link through a flexible joint. The anti-roll stabilizing bar end link connects in turn to a spot near a wheel or axle or on the axle, transferring forces from a heavily loaded axle to the opposite side.
Forces are therefore transferred:
Main Functions :-
Anti-roll stabilizing bars provide two main functions. The first function is the reduction of body lean. The reduction of body lean is dependent on the total roll stiffness of the vehicle.
The other function of anti-roll bars is to tune the handling balance of a car. Understeer or oversteer behavior will be tuned out.
