title: Anti-roll bar text: Anti-roll bar An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions 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 linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction. The first stabilizer bar patent was awarded to Canadian inventor Stephen Coleman of Fredericton, New Brunswick on April 22, 1919. Anti-roll bars were unusual on pre-war cars title: Anti-roll bar text: against the vehicle, kept at similar levels by the connecting sway bar. Because each pair of wheels is cross-connected by a bar, the combined operation causes all wheels to generally offset the separate tilting of the others and the vehicle tends to remain level against the general slope of the terrain. A sway bar is usually a torsion spring that resists body roll motions. It is usually constructed out of a cylindrical steel bar, formed into a "U" shape, that connects to the body at two points, and at the left and right sides of the suspension. If the left title: Anti-roll bar text: due to the generally much stiffer suspension and acceptance of body roll. From the 1950s on, however, production cars were more commonly fitted with anti-roll bars, especially those vehicles with softer coil spring suspension. An anti-sway or anti-roll bar is intended to force each side of the vehicle to lower, or rise, to similar heights, to reduce the sideways tilting (roll) of the vehicle on curves, sharp corners, or large bumps. With the bar removed, a vehicle's wheels can tilt away by much larger distances ("as shown by the SUV image at right"). Although there are many variations in design, title: Bullbar text: Bullbar A bullbar or push bumper (also (kanga)roo bar or 'nudge bar' in Australia, 'moose bumper' in Canada, and push bar, brush guard, 'grille guard', 'rammer' or 'cattle pusher' in the United States) is a device installed on the front of a vehicle to protect its front from collisions, whether an accidental collision with a large animal in rural roads, or an intentional collision with another vehicle in police usage. They range considerably in size and form, and are normally composed of welded steel or aluminium tubing, or, more recently, moulded polycarbonate and polyethylene materials. The "bull" in the name title: Anti-roll bar text: a common function is to force the opposite wheel's shock absorber, spring or suspension rod to lower, or rise, to a similar level as the other wheel. In a fast turn, a vehicle tends to drop closer onto the outer wheels, and the sway bar soon forces the opposite wheel to also get closer to the vehicle. As a result, the vehicle tends to "hug" the road closer in a fast turn, where all wheels are closer to the body. After the fast turn, then the downward pressure is reduced, and the paired wheels can return to their normal height
