What causes the clunking sound when driving over potholes?

[DeEmery]

When driving over potholes, the clunking sound you hear is a metallic noise, which occurs when the shock absorber compresses beyond its limit and bottoms out. Here's some relevant information about automotive shock absorbers: Introduction: To quickly dampen vibrations between the frame and body, and to improve ride smoothness and comfort, shock absorbers are generally installed in the vehicle's suspension system. The most widely used type in automobiles is the double-acting telescopic shock absorber. Fault detection: (1) Press down hard on the bumper and then release it. If the car bounces 2-3 times, it indicates the shock absorber is working properly. (2) When driving slowly and applying emergency brakes, if the car vibrates excessively, it suggests there may be an issue with the shock absorber.
