What is the purpose of a car sway bar?

[LaneRose]

The functions of a car sway bar are: When the horizontal heights of the left and right wheels are different, to prevent torsion of the bar body, the sway bar generates anti-roll resistance to suppress body roll. The sway bar refers to the front shock absorber top link, commonly known as a strut bar. The purpose of this device is to enhance body rigidity and improve the vehicle's stability during cornering. It is typically installed only in car modifications. The structural composition of a car sway bar is: 1. The two ends of the elongated bar body are respectively connected to mounting brackets via foot pieces, and the mounting brackets are assembled to the front wheel shock absorbers of the vehicle; 2. One end of the foot piece is connected to the bar body via an inner concave socket, while the other end is connected to the mounting bracket. The inner concave socket of the foot piece has two opposite through holes and a threaded hole on the side walls, allowing a bolt to pass through the corresponding through holes of the bar body for locking. The threaded portion of the bolt extends out and is secured with another lock nut, which increases the overall structural strength of the sway bar.
