构成车辆底盘的动力传动和行走系统这两大关键部分直接决定了底盘的操控性和舒适性,如果将动力传动装置比作人的心脏,那么行走装置就是人的两条腿;腿脚不灵活,即使有再强大的心脏也无法保证一个人快速行走甚至奔跑。而汽车悬挂装置就是保证车辆行驶平顺性、安全性和操控稳定性的关键。然而长期以来,我国大部分工程及特种车辆采用的是螺旋或钢板弹簧的传统机械式悬挂减振装置。
The two key components of the powertrain and travel system that form the chassis of the vehicle determine directly the handling and comfort of the chassis. If the power transmission is likened to the human heart, then the walking device is the two legs of a person; the legs are not flexible, Even with a powerful heart can not guarantee a person to walk quickly or even run. The vehicle suspension device is to ensure vehicle ride, safety and stability control of the key. However, for a long time, most of the engineering and special vehicles in our country use the traditional mechanical suspension damping device with spiral or leaf spring.
