What Does a Half-Shaft Abnormal Noise Sound Like?
1 Answers
Half-shaft abnormal noise is a sound of metal friction or metal collision. Below is relevant information about automotive half-shafts: 1. Principle: Due to the small contact area between the half-shaft and the drive wheel connection point, the sound of metal friction becomes particularly noticeable under heavy load. Additionally, there is a gap between the half-shaft and the wheel hub spline caused by the dust cover, leading to sticky friction at the contact surface of the half-shaft and wheel hub, thus generating abnormal noise. However, from the perspective of the entire vehicle, although the occurrence of abnormal noise is a flaw, it does not affect driving safety. 2. Classification: Automotive half-shafts are mainly divided into two types: full-floating half-shafts and semi-floating half-shafts. (1) Full-floating half-shaft: This type of half-shaft only transmits torque and cannot withstand all reaction forces and bending moments, making it widely applicable. Its advantage lies in easy disassembly and assembly; the half-shaft can be removed simply by loosening the bolts on the half-shaft flange, facilitating vehicle maintenance and repair. (2) Semi-floating half-shaft: This type of half-shaft can both transmit torque and withstand all reaction forces and bending moments. It has a simple structure and relatively low manufacturing costs, commonly used in cars with smaller reaction forces and bending moments.
