What does it mean when there's a loud clunk sound at 40 mph over a pothole?
1 Answers
When driving over a pothole, the clunking sound you hear is a metallic noise. If you don't avoid the pothole in time, the shock absorber will rapidly compress. When this compression exceeds its limit, the shock absorber will bottom out, producing a clunking sound, which is the metallic noise of the impact against the buffer block. Here's some additional information: 1. Shock Absorber: To accelerate the attenuation of vibrations between the frame and the body, thereby improving the vehicle's ride smoothness (comfort), most cars are equipped with shock absorbers in their suspension systems. Hydraulic shock absorbers are widely used in automotive suspension systems. Their working principle is that when the frame and axle move reciprocally and the piston moves back and forth inside the cylinder of the shock absorber, the oil inside the shock absorber's housing repeatedly flows from one chamber to another through narrow pores. 2. Precautions: If this happens, you should check whether the tire has developed a bulge or if any chassis components have been impacted. However, there's no need to worry too much, as every vehicle undergoes rigorous testing before leaving the factory, and it's rare to encounter the vehicle's limits in everyday life. If this occurs frequently over time, it can accelerate the aging and damage of the shock absorber. Therefore, when driving over potholes, always pass slowly, prioritizing safety.
