Selection of Optimal Planetary Transmission for Light Electric Vehicle Main Gearbox.

This paper deals with the selection of optimal layout variants of planetary transmissions designed for operation as Light Electric Vehicle main gearboxes. The required transmission ratio was calculated, and the optimal two-carrier gear train with two connecting and three external shafts selected. A computer program was used for structural synthesis and to determine the required basic parameters of the component gear trains. The ring gear reference diameter was used to rank the layout variants according to size, with the smallest variants also ranked according to the calculated efficiency ratio. Finally, an optimal variant of the planetary gear train for light electric vehicle application is proposed. The procedure proposed in this paper may be expanded to other applications.
