Fahrzeugstabilisatoren

Fahrzeugstabilisatoren, commonly known as anti-roll bars or sway bars, are a crucial component in modern vehicle suspension systems. Their primary function is to reduce body roll during cornering. When a vehicle turns, centrifugal forces cause the body to lean outwards. Stabilisatoren counteract this by resisting the independent movement of suspension components on opposite sides of the vehicle.

A typical stabilizer is a U-shaped torsion bar made of spring steel. It connects the left and right suspension components, usually via links. When one side of the suspension compresses more than the other, such as during a turn, the stabilizer bar twists. This twisting action creates a counter-force that tends to lift the higher side of the vehicle and lower the lower side, thereby keeping the body more level.

The effectiveness of a stabilizer is determined by its diameter, length, and the material it's made from. Thicker, stiffer bars provide more resistance to roll. While they enhance handling and stability, overly stiff stabilizers can sometimes lead to a harsher ride over uneven surfaces, as they link the suspension movements more directly. The design and tuning of vehicle stabilizers are a balance between agile handling and ride comfort. They are a standard feature on most passenger cars, SUVs, and performance vehicles.
