汽车底盘是除轮胎之外距离地面最近的部分,而安装在其上的悬挂系统对汽车的行驶与驾驶感受有着非常重要的作用。汽车在转向的时候为何动力依然能够输出到车轮上呢?这就要从万向节开始说起。所谓万向节,指的是利用球型等装置以实现不同方向的轴动力输出机构。万向节的作用如下图所示。根据万向节在扭转方向上是否有明显的弹性,可分为刚性万向节和挠性万向节。刚性万向节又可分为不等速万向节、准等速万向节和等速万向 The chassis of the car is the closest to the ground except the tire, and the suspension system mounted on it plays a very important role in driving and driving the car. Why does the power of the car still be able to be output to the wheels when turning? This starts with the universal joints. The so-called universal joints, refers to the use of ball-type devices to achieve different directions of shaft power output mechanism. The role of universal joints as shown below. According to the joint in the torsional direction whether there is obvious flexibility, can be divided into rigid universal joints and flexible universal joints. Rigid joints can be divided into non-constant velocity joints, quasi-constant velocity joints and constant velocity universal
