What is the function of a stabilizer bar?
1 Answers
The function of a stabilizer bar is to prevent excessive body roll during cornering and to improve the vehicle's stability when driving on uneven road surfaces. The stabilizer bar is a torsion bar spring made of spring steel, shaped like a U, and is installed horizontally at the front and rear of the vehicle. The middle part of the bar is connected to the frame with a sleeve joint, while the two 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 stabilizer bar does not function. When the vehicle body rolls, the suspensions on both sides move unevenly, causing the stabilizer bar to twist. The elasticity of the bar then acts as resistance to further rolling, providing lateral stability.
