What are the 4 components of the suspension system?

The four core components of a car's suspension system include shock absorbers, suspension springs, anti-roll bars, and guiding mechanisms. Shock absorbers suppress the oscillation of spring rebound through damping action to ensure driving stability; suspension springs, as elastic elements, support the vehicle body weight and cushion road impacts; anti-roll bars reduce the vehicle's roll amplitude when cornering through lateral rigid connections; guiding mechanisms (such as control arms, connecting rods, etc.) accurately transmit longitudinal and lateral forces while constraining the wheel movement trajectory. Suspension performance needs to balance softness and hardness-excessive softness can easily lead to brake dive or acceleration squat, while excessive hardness affects vibration absorption, so manufacturers will make targeted adjustments according to the vehicle's positioning.
