An anti-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 due to the generally much stiffer suspension and acceptance of body roll. From the 1950s, production cars were more commonly fitted with anti-roll bars, especially those 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, 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 against the vehicle, kept at similar levels by the connecting sway bar.
Ya no te espero
Llegarás, pero más fuerte
Más violenta la corriente
Dibujándose en el suelo
De mi pecho, de mis dedos
Llegarás con mucha muerte
Ya no te espero
Ya eché abajo ayer mis puertas
Las ventanas bien despiertas
Al viento y al aguacero
A la selva, al sol, al fuego
Llegarás a casa abierta
Ya no te espero
Ya es el tiempo que fascina
Ya es bendición que camina
A manos del desespero
Ya es bestia de los potreros
Saltando a quien la domina
Ya no te espero
Ya estoy regresando solo
De los tiempos venideros
Ya he besado cada plomo
Con que mato y con que muero
Ya se cuándo, quién y cómo
Ya no te espero
Ya he liberado a tu patria
Hija de una espera larga
Ya hay un primero de enero
Que funda a sus compañeros
Con la sed de mi garganta
Ya no te espero
Porque de esperarte hay odio
En un noche de novios
En los hábitos del cielo
En madre de un hijo ciego
Ya soy ángel del demonio
