The ball joint is actually a "joint" device. 1. The simplest hinge is that a pipe is sleeved on a shaft and can swing around the shaft. But if we need this tube on some occasions and can "rotate" around our center, how can we design it—— So the ball head came like this;

2. In fact, the structure of the ball head is very simple. One end is a steel ball and the other end is a "ball bowl" (which can be understood as "a hollow ball");

3. The "ball bowl" just wraps the steel ball, and the steel ball can rotate freely in the "ball bowl". The use of ball joints is very common in cars. For example, the pull rod of the steering machine and the joint of the suspension swing arm are specific application examples of the ball joint. The car ball joint is also called the universal joint, refers to the mechanical structure of the power transfer of different axes by the ball type connection. After the ball is damaged, if driving in the process of driving a car, the car will produce More obvious abnormal sounds, the stability of the car will also be poor.The car ball head is a power transmission of different axes by using a ball type connection, providing a multi-angle rotation such that the steering mechanism is smoothly turned smoothly, reducing vibration and achieving smooth steering.
