Abstract: Aiming at the abnormal noise produced by drive shaft of a pure electric vehicle during rapid
acceleration, and vibration and noise data of abnormal noise are tested, then the priority ranking of abnormal
noise source is identified by Hilbert transform, which is locked to the transmission shaft. Combined with the
working characteristics of drive shaft tripod universal joint, ball cage type universal joint and the analysis
results of wheel center vibration, it is identified that the abnormal noise comes from the extrusion friction when
the ball cage type universal joint moves at high speed. At last, by improving the composition proportion of
the grease, the lubrication performance is improved, and the internal lubricating film of the universal joint is
ensured to have a certain thickness. The effectiveness of the scheme is verified by the actual vehicle, which can
provide a reference for the subsequent investigation.
