Auto baten kolpeak xurgatzeko sistema malgukiz eta a osatuta dagokolpe xurgatzailea. The kolpe xurgatzailea 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 kolpe xurgatzailea gradually reduces the "small energy multiple impact". If you have driven a car with a broken kolpe xurgatzailea, you can experience the bouncing of the aftermath of the car going through every pothole and ups and downs, and the kolpe xurgatzailea is used to suppress this kind of bounce. Without a kolpe xurgatzailea, 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.
