Afin d'accélérer l'atténuation des vibrations du cadre et de la carrosserie et d'améliorer le confort de conduite (confort) de la voiture,amortisseurssont installés dans le système de suspension de la plupart des voitures.
Le système d'amortissement d'une voiture est composé d'un ressort et d'unamortisseur. The amortisseur 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 amortisseur gradually reduces the "small energy multiple impact". If you have driven a car with a broken amortisseur, you can experience the bouncing of the aftermath of the car going through every pothole and ups and downs, and the amortisseur is used to suppress this kind of bounce. Without a amortisseur, 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.
