Influence of inner meshing profile on noise of hybrid electric vehicles coupler chain based on vibration analysis [PDF]

open access: yesScientific Reports
Chain noise is an important factor affecting the ride comfort of hybrid electric vehicles (HEVs) with chain coupler. The inner meshing profile can effectively reduce the polygonal action, which has already been proved, but its influence on the noise is ...
