What is Vehicle Suspension?
2 Answers
Vehicle suspension refers to the support system composed of springs and shock absorbers between the body and tires. Its types include: double wishbone, single wishbone, trailing arm, semi-trailing arm, and multi-link. The functions of vehicle suspension are: to transmit forces and torques between the wheels and the frame, to cushion the impact force transmitted from uneven road surfaces to the frame or body, to dampen the resulting vibrations, and to ensure smooth driving. Methods to determine if a vehicle's suspension is damaged include: 1. The steering wheel becomes heavy and vibrates; 2. The shock absorber leaks oil, makes abnormal noises, or fails; 3. The car pulls to one side; 4. When encountering bumpy roads, the car vibrates up and down, and the body twists; 5. Obvious braking nod; 6. Abnormal noises from the body while driving.
The vehicle suspension is the system underneath my car, responsible for absorbing road bumps and making the drive smoother and more comfortable. I remember when I first bought the car and drove over a rough patch of road—the body didn’t bounce as much, all thanks to the suspension’s damping effect. It uses springs to cushion impacts, shock absorbers to control rebound, and connects the wheels to maintain stability. Beyond comfort, suspension also plays a crucial role in safety, especially in preventing tire slippage during turns or sudden braking. In daily driving, I’ve noticed that softer suspensions are great for long trips, while stiffer ones enhance handling and a sportier feel. Overall, with a good suspension, the driving experience becomes much more relaxed, and you won’t feel every bump rattling your bones.
