QUANTUM 和 e-AAM 被 Motor Trend 列入“有前途的技术”列表

为了寻找有望推动整个汽车行业未来发展的科学与制造先进技术，Motor Trend 团队参观了最近举行的 WCX17:SAE World Congress Experience 展览，以寻找令人兴奋的未来技术。

他们列出的值得一提的 12 项技术的清单中包括两项 AAM 先进技术 – QUANTUM™ 和 e-AAM™。

QUANTUM 轻量化和高效车桥技术 可扩展到各个车辆领域，无论车辆尺寸如何，均可提供巨大的优势，包括重量更轻、功率密度更高、NVH 更优、效率更高、系统布置更紧凑。

“这种概念车桥全面地重新布置了典型后驱车桥中的齿轮和轴承，使扭矩密度提高了 20%，质量降低了 30%。据 Motor Trend 称：“它的体积也更小，并且模块化程度更高，因为许多部件和一半壳体可以保持不变，而另一半则可选择开式齿轮传动装置、电动或机械锁定装置，甚至扭矩矢量分配系统。”

“锦上添花：在传统车桥中为了确保准确安装准双曲面齿轮以实现最佳耐用性和 NVH 而使用的垫片，在将噪音降低 5 dB 的同时会被灰烬覆盖。AAM 正与多个 OE 谈判，目标是在 2021 年或之前投入生产。”

e-AAM 混合动力和纯电传动系统 可提高燃油效率，减少尾气排放，并改善动力安全性、加速性能和 eAWD 牵引力。

Motor Trend 表示：“很多车辆都吹嘘自己采用带有电动后桥的前轮驱动燃烧系统，但 e-AAM 装置在车辆转弯时为外轮增加了一个有趣的变化。没错，是有一个扭矩矢量分配模式，但其工作原理与大多数模式不同。电机以 9:1 至 11:1 的单速齿轮减速比连接到车桥，但是还有一个行星齿轮组可以实现三种模式：空档（在高速或不需要时断开电动机）、开式差速器模式和扭矩矢量分配模式。”

“在此模式下，使电机沿一个方向或另一个方向旋转会在向右或向左转弯时将扭矩偏向外轮。请注意，在这种扭矩矢量分配应用过程中，e-AAM 本身并不提供任何推力。

AAM 正在开发另一个版本，其中增加了第二个电动机以允许同时进行推进和扭矩矢量分配。该系统尚未投入生产，但已有不止一家 OEM 正努力将这种概念以其众多尺寸和扭矩能力之一应用到生产中。”

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief as of that time with respect to future events and are subject to risks and may differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

  • reduced purchases of our products by General Motors Company (GM), FCA US LLC (FCA), or other customers;
  • reduced demand for our customers' products (particularly light trucks and sport utility vehicles (SUVs) produced by GM and FCA);
  • 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;
  • risks related to a failure of our information technology systems and networks, and risks associated with current and emerging technology threats and damage from computer viruses, unauthorized access, cyber attack and other similar disruptions;
  • global economic conditions;
  • our ability to maintain satisfactory labor relations and avoid work stoppages;
  • our suppliers', our customers' and their suppliers' ability to maintain satisfactory labor relations and avoid work stoppages;
  • price volatility in, or reduced availability of, fuel;
  • our ability to protect our intellectual property and successfully defend against assertions made against us;
  • our ability to attract and retain key associates;
  • availability of financing for working capital, capital expenditures, research and development (R&D) or other general corporate purposes including acquisitions, as well as our ability to comply with financial covenants;
  • our customers' and suppliers' availability of financing for working capital, capital expenditures, R&D or other general corporate purposes;
