How are uprights connected to the anti roll bar?
Drop links connect the uprights to the anti-roll bar and a torsional spring resists torsion caused by vertical movement in opposite directions of the uprights. Each side of the anti-roll bar is connected to the body by a hinge joint. In this way, the torsion spring resists roll but leaves heave unaffected.
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.
How does the torsion bar affect the suspension?
The torsion bar does not contribute to the suspension spring stiffness (the suspension’s resistance to vertical deflection) as its unsprung weight is increased or when the driven vehicle is subjected to dynamic shock loads caused possibly by gaps or ridges where concrete sections of the road are joined together.
How does anti roll bar affect Dynamic Ride?
Dynamic ride characteristics of the vehicle employing unconnected, unconnected with anti-roll bar and interconnected suspensions are analyzed in terms of transient vertical and roll response of the sprung mass, when subjected to half-sine displacement excitations at the tire-terrain interface.

Why do front wheel drive cars have anti roll bars?
This can be used to advantage: many front wheel drive production cars lift a rear wheel when cornering hard in order to overload the opposite wheel, limiting understeer . Diagram of two types of adjustable antiroll bars.
What kind of load can an ARB bar take?
In certain situations, ARB that is tuned can take as much as 30%–40% of the total vertical load imposed on the suspension when subjected to severe body roll [61]. ARB also has a cross section that is usually divided into three types, including solid circular, hollow circular, and solid tapered.
