The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road. The axle can be integral, with the body supported by the suspension system at both ends. Therefore, the integral axle is usually used with a non-independent suspension; the axle can also be disconnected, like two umbrellas inserted on both sides of the body, and then each supports the body through the suspension system, so the disconnected axle is used with an independent suspension. After the existing automobile axles are produced, their compressive strength needs to be tested to a certain extent, so the axle testing device will be used.
