關(guān)鍵詞:新能源汽車 變速器
Abstract:High-speed gearbox is the key functional component of the electric drive system of new energy vehicles, and its efficiency, life and noise directly determine the performance and reliability of the whole vehicle. This paper states the advantages and types of new energy vehicle transmissions, analyzes the key transmission technologies, and is of great significance for the forward design of high-speed gear gearboxes and the manufacturing technology of key parts, and promotes the strategic layout of the new energy vehicle industry.
Key words:new energy vehicles, transmissions
1 引言
新能源電動(dòng)汽車的電機(jī)由于具有低速,即使轉(zhuǎn)速為零也可以產(chǎn)生很大轉(zhuǎn)矩和轉(zhuǎn)速非常廣的0-7000rpm工作范圍這兩個(gè)典型特點(diǎn),在沒有搭載離合器與變速器的情形下,電動(dòng)汽車仍然可以正常工作,來完成行駛的基本功能。(剩余4003字)
