How to Determine if a Car's Half Shaft is Damaged?
1 Answers
When a car's half shaft is damaged, it may cause the wheel to fall off during high-speed driving; an out-of-round wheel hub can lead to inaccurate dynamic balance, manifesting as steering wheel vibration at high speeds. A deformed half shaft in a sedan will result in severe shaking when driving. Below is an introduction to vehicle half shafts: 1. Introduction: The half shaft is a solid shaft that transmits torque between the differential and the drive wheel. Its inner end is usually connected to the half shaft gear via splines, and the outer end is connected to the wheel hub. 2. Classification: Modern vehicles commonly use two types of half shafts based on their support styles: full-floating and semi-floating. 3. Advantages: The semi-floating half shaft not only transmits torque but also bears all reaction forces and bending moments. Its support structure is simple and cost-effective, making it widely used in various sedans with smaller reaction bending moments.
