Zorluk: OrtaSuspension Systems

A passenger sedan maintains proper ride height and dampens vertical road impacts normally, but it leans excessively toward the outside when making sharp turns. Which suspension component is specifically designed to resist this lateral body roll?

  1. A
    Shock absorber
  2. B
    Coil spring
  3. Stabilizer barCevap
  4. D
    Ball joint

Cevap

The stabilizer bar (sway bar) is the component engineered to resist lateral chassis lean during cornering.
The stabilizer bar, also known as a sway bar or anti-roll bar, is a transverse steel torsion bar that connects the left and right suspension control arms. When cornering forces compress the outside suspension and extend the inside suspension, the bar twists and transfers load, pulling the chassis back level and minimizing body roll.

Adım Adım Çözüm

1
Analyze the vehicle symptom and operating condition.
The vehicle handles normal vertical bumps smoothly without bouncing or sagging, but experiences excessive lean when cornering.
Isolating cornering body roll from vertical ride height and damping isolates the stabilizer linkage from springs and dampers.
2
Identify the component designed to transfer torsional load across the vehicle axle.
The stabilizer bar connects the left and right control arms, twisting to counteract unequal suspension travel during cornering.
Springs support weight and shock absorbers dampen bounce, whereas the stabilizer bar provides anti-roll stiffness.
