What are the causes of abnormal noise in the automotive steering system?

The causes of abnormal noise in the automotive steering system are: 1. Air entrainment in the steering system: In the suction area of the hydraulic oil pump, cavitation occurs due to low pressure. When bubbles move to the high-pressure area, their volume is compressed, and when they return to the low-pressure area, their volume increases, generating noise; 2. Noise caused by control valves: Improper matching between the flow control valve hole and the valve core, or dirt jamming the sealing area between the safety valve cone and the valve seat, as well as non-circular or defective sealing bands, can all produce noise; 3. Noise caused by mechanical vibration: When installing the steering pump, ensure that the coaxiality error between the pump shaft and the main shaft is less than 0.1mm and the inclination angle is less than 30 degrees. The steering pump speed should not be too high to avoid bearing damage and noise generation.
