AAM 介绍先进的 EV 技术，包括 CTI 新的三合一电驱动

底特律，2021 年 9 月 8 日 – 来自美国车桥制造有限公司的技术专家将在 2021 年美国 CTI 研讨会上展示公司的电动汽车产品组合，包括高效的下一代电动驱动装置。AAM 活动包括技术演示和小组讨论。

CTI 研讨会汇集了汽车制造商、供应商、学术界和政府机构，展示最新的技术、战略、市场趋势和要求，重点是传统和电气化传动系统、纯电动传动系统、子系统以及支持技术和工具。今年的重点是到 2050 年实现净零排放的途径。

AAM 产品工程副总裁 Craig Renneker 表示：“AAM 专注于开发支持全球电动汽车发展的技术。”“我们在 CTI 演示期间展示的最新技术在效率、减重和动力方面处于领先地位。”

Renneker 将参加关于电池电动汽车未来的小组讨论。在“100% BEV 在未来能实现吗？”这一问题的专家讨论中，Renneker 将与来自汽车制造商和供应商的其他业内人士一起讨论电动汽车的格局。

AAM 还将在展会的两场技术会议上发言，包括：

电池电动卡车，配备提供超过 450 千瓦功率的三合一高速电驱动

发言者是 AAM 平台电气化与 ECS 执行总监 Joseph Mueller

下一代电驱动系统将包括高转速 eMachine、高减速变速箱和高度集成的逆变器，它们将实现模块化三合一电驱动系统，这些系统将比当前产品更节能且更经济实惠。AAM 的模块化电驱动系统可针对多个 BEV 和 PHEV 架构量身定做。应用将包括低功率、高价值的 A 段应用、使用永磁和感应机的四轮驱动系统，甚至包括适用于美国轻型皮卡市场的大功率和扭矩双电机解决方案。

AAM 已经制造了一辆全尺寸的皮卡演示车来展示这项技术。它包括前桥的单电机系统和后桥的双电机系统，其中包括锁定差速器。

带集成逆变器的电架车桥

发言者是 AAM 高级技术经理 Greg Marsh

AAM 为轻型卡车提供的电架车桥采用下一代电驱动系统，配备 24k rpm eMachine、高减速变速箱和高度集成的逆变器。

该系统采用了新技术，包括更快的 eMachine 转速、独特的冷却方法、高比变速箱，以及逆变器的完全集成。24k rpm 的高转速在功率密度方面具有非常明显的优势，并可减轻 25% 的 eMachine 质量，从而显著节省 eMachine 材料成本。

开发了独特的冷却方法，使高速、高功率的 eMachine 能够提供持续的峰值功率水平。开发了独特而创新的贯通定子和贯通轴冷却（有别于传统的水套外壳冷却），以获取更接近源的热量。

竞争性的电架车桥不包括车载逆变器，需要高压交流电缆和逆变器才能在车辆侧包装。车桥还可以配备开放式、可选择的锁式或有限的滑差。

  • our ability to develop and produce new products that reflect market demand;
  • lower-than-anticipated market acceptance of new or existing products;
  • our ability to respond to changes in technology, increased competition or pricing pressures;
  • our ability to attract new customers and programs for new products;
  • our ability to consummate and integrate acquisitions and joint ventures;
  • risks inherent in our international operations (including adverse changes in trade agreements, tariffs, immigration policies, political stability, taxes and other law changes, potential disruptions of production and supply, and currency rate fluctuations, including those resulting from the recent United States presidential election and the United Kingdom's vote to exit the European Union);
  • negative or unexpected tax consequences;
  • liabilities arising from warranty claims, product recall or field actions, product liability and legal proceedings to which we are or may become a party, or the impact of product recall or field actions on our customers;
  • our ability to achieve the level of cost reductions required to sustain global cost competitiveness;
  • supply shortages or price increases in raw materials, utilities or other operating supplies for us or our customers as a result of natural disasters or otherwise;
  • our ability or our customers' and suppliers' ability to successfully launch new product programs on a timely basis;
  • our ability to realize the expected revenues from our new and incremental business backlog;
