摘要
为了满足全球范围内对生态友好型交通系统的需求,最近对电动汽车(EV)的需求有所增加。汽车电气化为多个领域的研究开辟了许多新的选择和机会。在传统电动汽车中,单个电机通过减速齿轮和机械差速器(MD)为汽车提供动力。MD是每辆汽油动力汽车或内燃机汽车的重要组成部分,在转弯时可改变驱动轮的速度。然而,MD 有相当大的摩擦损失,体积大,重量重,结构设计复杂。因此,新型节能电动汽车动力传动系统采用电子差速器(ED)代替传统的 MD。与 ED 相关的动力传动系统被称为分布式电动汽车动力传动系统。与传统的动力传动系统不同,分布式动力传动系统使用独立配备的电机来驱动车辆。
Electronic differential: A vital component of electric vehicles
The demand for electric vehicles (EVs) has increased recently to meet the desire for an ecofriendly transportation system on a global scale. The electrification of vehicles opens up a number of new options and opportunities for doing research in several fields. In a conventional EV, a single electric motor powers the car through reduction gears and the mechanical differential (MD). A crucial component of every gasoline-powered car or internal combustion engine vehicle is the MD, which modifies the speed of the driving wheels during cornering maneuvers. However, the MD has considerable friction losses, is big and heavy, and has a complicated structural design. As a result, the new energy-efficient EV drivetrain uses an electronic differential (ED) in place of the traditional MD. The drivetrains associated with an ED are known as distributed EV drivetrains. Unlike conventional drivetrains, the distributed drivetrains use independently equipped motors to drive the vehicle.
