Pentru a accelera atenuarea vibrațiilor cadrului și a caroseriei și pentru a îmbunătăți confortul la mers (confortul) mașinii,amortizoaresunt instalate în sistemul de suspensie al majorității mașinilor.
Sistemul de absorbție a șocurilor unei mașini este compus dintr-un arc și unamortizor. The amortizor is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact. The spring plays the role of alleviating the impact, changing the "high energy one impact" into "small energy multiple impact", and the amortizor gradually reduces the "small energy multiple impact". If you have driven a car with a broken amortizor, you can experience the bouncing of the aftermath of the car going through every pothole and ups and downs, and the amortizor is used to suppress this kind of bounce. Without a amortizor, the rebound of the spring cannot be controlled. When the car encounters a rugged road, it will have a serious bounce. When cornering, the tire's grip and tracking will be lost due to the vibration of the spring.
