How Does an Anti-Roll Bar Work?

[NicoleDella]

When the vehicle body moves only vertically and the suspension deformations on both sides are equal, the anti-roll bar rotates freely within the sleeve, and the anti-roll bar does not function. Here is the relevant introduction: 1. Function: Its purpose is to prevent excessive lateral roll of the vehicle body during cornering. The goal is to prevent the car from rolling over sideways and to improve ride comfort. 2. Composition: The anti-roll bar is a torsion bar spring made of spring steel, shaped like a "U," and installed horizontally at the front and rear of the vehicle. The middle part of the bar is hinged to the frame with a sleeve, and both ends are fixed to the left and right suspensions. When the vehicle body moves only vertically, the deformations of the suspensions on both sides are the same, and the anti-roll bar does not function. When the vehicle body rolls, the suspensions on both sides move unevenly, causing the anti-roll bar to twist, and the spring force of the bar becomes resistance to further rolling.
