What is the function of a car stabilizer bar?

[BrookeRose]

The function of a car stabilizer bar is to achieve handling balance and limit body roll during cornering, thereby improving tire grip performance. Simply put, when a car turns at high speed or travels on uneven roads, it tends to twist and is prone to tilting, which can lead to vehicle rollover. The stabilizer bar enhances the stability of the body during cornering, preventing excessive tilting. Common types of stabilizer bars include anti-roll bars, Watt's linkages, and Panhard rods. The stabilizer bar can connect the car's suspension components into a unified whole, increasing body rigidity, effectively preventing body deformation, balancing the torque between two wheels, preventing alignment displacement, reducing wheel bumpiness, extending the lifespan of suspension components, and avoiding a sense of powerlessness and body roll during cornering. It enhances both vehicle safety and driving maneuverability while improving ride comfort.
