| Abstract: | The current development of new energy vehicles was reviewed firstly in this paper.Aiming at the structure of transmission to be used in new energy vehicles based on novel transmission principle,three major problems were summarized.Furthermore,the possible solutions were proposed.Firstly,die casting process was computed and optimized to reduce the deformation and conventional defects.Secondly,high-silicon aluminum alloy with optimized alloy composition was developed to improve the hardness of traditional aluminum alloys.Finally,the internal gear was partially strengthened by micro-arc oxidation method(MAO) to promote its hardness and the abrasive resistance.Thus,the life of gear blank was ultimately prolonged. |
