Tech Tip: Mercedes-Benz Steering System Grinding/Gushing Noises  / April 05, 2011

If you receive customer reports of grinding or gushing noises, which may be heard from the area of the steering system/power steering pump, one of the possible causes may be in the A/C compressor belt drive. This noise is similar to the noise produced by the power steering pump when ingesting air. This type of noise is present at both idle and higher engine speeds, can be heard whether the steering wheel is stationary or moving, and the noise frequency increases with the engine speed. The noise intensity increases toward steering wheel end limit stops.

最近看了很多资料  对于动力转向系噪音觉得不是很清晰：
Drinding / gushing noise； groaning / growling noise； hissing noise； whining / moan / whimper noise； screech / clunking noise；
各种噪音定义术语频出，不知道国内汽车整车及零部件厂商有没有自己的一个定义规范来学习一下呢？
期待后续兄弟的跟贴：
