High-Speed Vehicle Body Vibration?
2 Answers
The causes of high-speed vehicle body vibration are as follows: 1. Uneven brake disc surface with significant radial runout, caused by uneven braking force or misaligned brake pads. 2. Excessive tire pressure, leading to pronounced vehicle vibration when driving at high speeds on uneven roads, making it easy for the driver to feel the body shaking and pulling to one side. 3. Severe tire wear with significant imbalance in dynamic balance, resulting from uneven wear or large dynamic imbalance, causing the tires to bounce at high speeds and leading to body vibration. 4. Engine issues, typically due to fuel quality or ignition problems. Under high-speed and high-load conditions, fuel quality and ignition determine the power output. If either of these is abnormal, it can cause the engine to lose power and vibrate.
Having driven for over twenty years, when encountering body vibration on the highway, the first thing that comes to mind is tire issues. It could be due to improper wheel balancing or uneven tire wear, leading to unstable body movement. Additionally, deformed rims or aging shock absorbers in the suspension system can also cause vibrations. Last week, my relative's car was shaking severely, and upon inspection, it was found to be a bulging tire. The issue was resolved by replacing the tire and performing wheel balancing. It's advisable to promptly conduct a four-wheel alignment check and not delay, to prevent loss of control at high speeds. Regular tire maintenance can prevent problems before they occur; never overlook minor symptoms, as they can escalate into major hazards, affecting overall driving safety.
