Description

一种电动车自动变速器
技术领域
本发明涉及纯电动汽车的自动变速器。
背景技术
目前，纯电动汽车的自动变速器在国内基本上属于真空状态。E-AMT相比其他变速箱，具有绝对的市场优势。而电动汽车行业的发展和政策导向，也说明了E-AMT自动变速器在未来的发展前景。
国内外在电动汽车多挡化方面都有相关的研究，意大利“OerlikonGraziano”公司开发出了匹配小型电动汽车的两挡变速器，仿真表明可以明显降低电池能耗；在国内，北京理工大学针对北京奥运电动客车开发了3挡机械式自动变速器（无离合器），使整车的经济性提高了9％，0～50km/h的加速时间减少了18％；多挡变速器通过对传动***的控制可使牵引电机工作在理想的区域，从而提高整车的动力性、经济性等指标。
国内某汽车公司的一款采用固定速比减速器的电动车的基础上，采用两挡变速传动方案，对驱动电机进行了参数匹配设计，设计了不带离合器的两挡自动变速器，制定了以电机高效运行为原则的换挡控制策略，对传动***的速比进行了以整车动力性要求为约束、以ECE（欧洲城市经济）循环工况下电机能量消耗最小为目标的优化设计，并与采用固定速比减速器的电动汽车进行了ECE运行循环下的能耗和续驶里程的对比，结果表明，整车能耗降低了6.6％，续驶里程延长了7.1％；
但与丰富的基础理论研究不同的是，目前电动汽车自动变速器的产业化，还远没有到达到满足电动汽车迅猛发展的要求。纯电动汽车自动变速器在整车应用上，还远远落后于行业的脚步。目前市场上尚无一款成熟的、能大规模生产的纯电动汽车自动变速器。
发明内容
本发明的目的是设计一种新型的低成本、轻量化，以及更长使用寿命的电动车自动变速器。
本发明的技术方案是：一种电动车自动变速器由右壳体、左壳体、差速器、输出齿轮、高档输出齿轮、低档输出齿轮、高档输入齿轮、低档输入齿轮、换挡齿、换挡拉杆、换挡拨叉、换挡弹簧、顶齿弹簧、换挡凸轮、选档电机轴、选档电机、选档电机支架、以及车速信号传感器一、车速信号传感器二、档位位置信号传感器组成，其特征在于：
正常情况下，当驱动电机驱动时，变档齿轮箱处于高速运行状态，即电机输入齿轮与高档输出齿轮啮合，变速器处于高速工作状态，驱动电动车运行；
当遇到爬坡或重载需要大的转矩时，通过控制器启动选档电机，选档电机通过车速传感器一和车速信号传感器二及档位位置信号传感器，将信号传递给控制***，通过换挡拨叉带动换挡凸轮，将高档输入齿轮分离，使电机输入齿轮切换到与低档输出齿轮啮合，使变速器处于低速工作状态，驱动电动车在慢速下运行。
本发明的有益效果：
本发明解决了由于通过变档杆手动操作，导致变档时间慢，变档切换过程出现故障导致无法变档的问题。
仿真结果显示采用采用本自动变速器后，新匹配的驱动电机峰值功率降低了8.57%，最大转矩降低了8.5％；新匹配的两挡变速汽车的动力性满足原车型设计要求，且0～50km/h起步加速时间减少了0.26s，最高车速提高了22.84km/h。而在经济性上，采用两挡自动变速器使整车的能耗降低了6.6%，续驶里程延长了7.1%。由仿真结果比较可以看出采用两挡自动变速器，可以使电机更多地工作在高效区，其原因是采用两挡变速器时，电机的工作转矩比采用固定挡减速器小得多，这样就减小了电机的工作电流，降低了电机的绕组损耗，提高了电机的工作效率。
附图说明
附图1为本发明的示意图一。
附图2为本发明的示意图二。
具体实施方式
为了使本技术领域的人员更好地理解本发明方案，并使本发明的上述目的、特征和优点能够更加明显易懂，下面结合实施例对本发明作进一步详细的说明。
具体实施例如图1、图2所示，一种电动车自动变速器由右壳体1、左壳体2、差速器4、输出齿轮5、高档输出齿轮6、低档输出齿轮7、高档输入齿轮8、低档输入齿轮9、换挡齿11、换挡拉杆13、换挡拨叉14、换挡弹簧15、顶齿弹簧16、换挡凸轮17、选档电机轴18、选档电机19、选档电机支架20、以及车速信号传感器一21、车速信号传感器二22、档位位置信号传感器23组成，其特征在于：
正常情况下（选择转矩1），当驱动电机3驱动时，变档齿轮箱处于高速运行状态，即电机输入齿轮10与高档输出齿轮6啮合，变速器处于高速工作状态，驱动电动车运行；
当遇到爬坡或重载需要大的转矩时（选择转矩2），通过控制器启动选档电机19，选档电机通过车速传感器一21和车速信号传感器二22及档位位置信号传感器23，将信号传递给控制***，通过换挡拨叉14带动换挡凸轮17，将高档输入齿轮8分离，使电机输入齿轮10切换到与低档输出齿轮7啮合，使变速器处于低速工作状态，驱动电动车在慢速下运行。
本发明解决了由于通过变档杆手动操作，导致变档时间慢，变档切换过程出现故障导致无法变档的问题。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
