校園電動(dòng)車設(shè)計(jì)（含CAD圖紙、word說(shuō)明書】

摘要校園電動(dòng)車是近幾年出現(xiàn)的一種新興交通工具。校園電動(dòng)車有著節(jié)能，環(huán)保，便捷等諸多的優(yōu)點(diǎn)。因此本課題具有很強(qiáng)的現(xiàn)實(shí)意義和接近實(shí)際水平的設(shè)計(jì)要求，尤其是對(duì)機(jī)械設(shè)計(jì)部分和電氣控制部分的設(shè)計(jì)。 本畢業(yè)設(shè)計(jì)主要進(jìn)行了電動(dòng)車的機(jī)械部分的分析和設(shè)計(jì)，包括電動(dòng)車的減速器、差速器、軸承的選擇設(shè)計(jì)、各主要零部件的強(qiáng)度校核與計(jì)算、以及基本的機(jī)械傳動(dòng)部分的實(shí)現(xiàn)等。通過(guò)所設(shè)計(jì)好機(jī)械各部分或者整體部分的結(jié)構(gòu)以及相關(guān)尺寸，利用制圖軟件CAD進(jìn)行相關(guān)的配圖的繪制以及其他零件圖的繪制。 根據(jù)電動(dòng)車前進(jìn)、后退、制動(dòng)等基本控制要求，給出電動(dòng)機(jī)的電氣控制設(shè)計(jì)。關(guān)鍵詞: 校園電動(dòng)車；交通工具；強(qiáng)度校核；機(jī)械傳動(dòng)AbstractCampus electric vehicle is the emergence of a new transport in recent years. Campus electric car has energy-saving, environmentally friendly, convenient, and many other advantages. Therefore, this issue has a strong practical and realistic level design requirement, especially the part of design for mechanical design and electrical control part. The graduation project is mainly for the electric vehicle analysis and design of mechanical parts. Including electric reducer, differential, bearing choice design, the major components Strength check and calculation, and basic mechanical transmission part of the implementation and so on. Designed by a good mechanical parts or the whole part of the structure and related dimensions, Use graphics software related with CAD drawing and other component drawing.According to electric cars forward, reverse, brake control and other basic requirements, electrical motor control design can be given.
