电动汽车的改装设计 摘要 由于电动机与发动机的动力特性不同,所以改装涉及了多个方面,包括电机的选用,传动系统的改装,线路的设计及用电安全．本文中改装的汽车为驾校训练使用，要求行驶速度为２～３kmph．根据这一要求得出驱动汽车所需力矩和功率，据此选择电动机．由电动机输出转速确定传动比，从而改装传动系统．最后考虑供电线路的布置及用电安全． 关键词:驾驶训练、汽车改装、电动车、 THE REFIT OF BEIJING JEEP BJ2020S Abstract We discuss the refit of BeiJing Jeep BJ2020s in this paper. Remove the engine,change a motor instead. The jeep used in the driving school is driving at the speed of only 2~3 kmpf .It is result that the power of the engine runs low ,and it pollute much .In recent years ,the price of the oil is too high ,so using oil in training become very expensive .As a result ,we hope that motor can be used in the jeep instead of the engine .In this way we will reduce the cost of training and the pollution . Because of the difference of the characteristic between engines and motors, refit involve several aspects. Including many ways ,for example to chose a motor ,refit the driving systems ,design the circuitry and the safety of the electricity .The car in this paper is a training car in driving school ,it is requited to run at the speed of 2~3 kmph. To meet the need ,we can gain the moment and the power needed ,in this way we will get a motor .When the motor is chosen ,we have a output rate .So the driving radio is determined. To get the driving radio we have to refit the driving systems .At last we have to design the electricity line and make sure it is safe . KEY WORD:driving training ,refit jeep ,motor jeep 目录 摘要……………………………………………………………………1 Abstract………………………………………………………………………2 绪论………………………………………………………………… ..4 引言…………………………………………………………….4 汽车改装前后经济性比较………………………………….7 汽车改装难度分析…………………………………………….7 汽车改装后对环境的影响………………………………………10 改装……………………………………………………………… 11 2.1 计算所需驱动力矩及功率……………………………………11 2.2选择电动机……………………………………………………..12 2.3初步确定传动方案…………………………………………12 2.4计算并确定传动方案……………………………………………….13 2.5作零件图、装配图…………………………………………………..30 2.6布置供电线路及检查电路安全……………………………………30 结论………………………………………………………………………..36 致谢…………………………………………………………………………37 参考文献…………………………………………………………………….3
