摘要

全球汽车行业的发展趋势是向不排放废气、使用环保燃料的电动汽车发展。与内燃机汽车相比，电动汽车更环保，因为它们排放的二氧化碳和污染物更少。在快速增长的电动汽车市场中，生产新型电动汽车的研发工作正在积极进行。本研究开发了一种适用于 300 牛米级电动汽车的双速电动汽车变速器。双速变速器的结构可实现高效的能源利用，并采用了行星齿轮组和湿式多片离合器，在动力传输过程中效果显著。通过本文的研究成果开发出的双速变速器结构紧凑，专为电动汽车而优化。通过对原型的性能测试，验证了变速器设计的可行性，有助于提高燃油效率和改善环境。

Two-Speed Transmission Structure and Optimization Design for Electric Vehicles

The trend in the global automotive industry is moving towards electric vehicles that do not emit exhaust gases and use eco-friendly fuel. Electric vehicles are more eco-friendly compared to internal combustion engine vehicles, as they emit less carbon dioxide and pollutants. Research and development are actively underway to produce new electric vehicle models in the rapidly growing electric car market. In this study, a 2-speed transmission for electric vehicles, applicable to 300 Nm-class electric cars, has been developed. The 2-speed transmission structure enables efficient energy use and utilizes a planetary gear set and wet multi-plate clutch, which are effective in the power transmission process. The 2-speed transmission developed through the research results of this paper has a compact structure optimized for electric vehicles. The design feasibility of the transmission was verified through performance tests of the prototype, contributing to fuel efficiency improvement and environmental enhancement.
