Abstract
This article describes a technique for the differential bearings noise reduction. Noise results from the mechanical looseness of the differential gear and connected elements and it is activated by the vibrations of the engine. A test rig for simulation of the phenomenon outside vehicle has been designed and behavior of the differential bearing has been analyzed. Analytical software that is capable to classify the types of the noise has been created. The mathematical model enables estimation of suitable range of differential bearings radial stiffness. Finally, the selected solution is tested on the test rig, thus the technique is verified.
