AAM 的全新 QUANTUM 动力传动系统技术减轻了轴重并提高了效率

American Axle & Manufacturing (AAM) 抛弃了车桥设计蓝图，从头开发出全新且得到显著改进的车桥技术。QUANTUM 动力传动系统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 – 重量更轻、功率密度更高、NVH 更优、效率更高、系统布置更紧凑

底特律– 2017 年 3 月 29 日 – 车桥是车辆最关键的系统之一，它将动力和扭矩从变速器和传动轴传递到车轮。这个经过验证的系统几十年来没有发生明显变化。直到现在。直到 QUANTUM™ 面世。

American Axle & Manufacturing (AAM) 抛弃了车桥设计蓝图，从头开发出全新且得到显著改进的车桥技术。QUANTUM 动力传动系统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 – 重量更轻、功率密度更高、NVH 更优、效率更高、系统布置更紧凑。

AAM 董事长兼首席执行官 David C. Dauch 表示：“很简单，AAM 的 QUANTUM 将打破市场格局。”“我们的工程师将最初的一点点创意火花发展成如今的成熟技术，这项技术可提高车辆效率、改善燃油经济性并增加功率密度。我们的客户将会发现全然不同的车桥系统，而驾驶者将会发现全然不同的气泵。”

全新车桥设计

AAM 的高级工程师有一个大胆的想法。我们能不能重新设计和改造车桥来提高效率？在对非汽车产品进行长达数年的基准测试、花费无数个小时的开发时间、进行艰苦的硬件测试并获得几十项专利之后，AAM 的工程师重新设计了传统车桥的几乎所有部件。最终，QUANTUM 车桥系列在减轻系统重量的同时，显著改善了效率、性能和布置。

AAM 副总裁兼首席技术官 Phil Guys 表示：“它的各项数据令人称奇。”“在相同的扭矩能力下，QUANTUM 的功率密度增加了 20%，而重量减轻了至少 30%。对于重型皮卡，QUANTUM 可将车辆重量减轻 100 磅以上。在不降低性能的情况下，显著提高了效率。”

QUANTUM 的新设计主要是以全新方式使用传统车桥部件。轴承布置更高效，并且齿轮设置在最佳位置。AAM 的工程师利用系统创新来减轻重量，他们将许多部件的功能结合在一起，并开发出专用润滑油，提高了系统的效率和耐用性。传统车车桥使用垫片来确保准确安装车桥的准双曲面齿轮，以实现最佳的耐用性和 NVH。由于 QUANTUM 的智能设计，工程师能够消除对垫片的需求，同时仍可将 NVH 性能提高，改善多达 5 dB。

Guys 表示：“QUANTUM 的创新齿轮和轴承设计加上优化的外壳，使 AAM 大大减少了布置空间。” “这意味着我们的客户可以获得宝贵的空间用于其他对他们客户而言很重要的车辆内容，例如更低的货厢地板，甚至更大的油箱。”

QUANTUM 可扩展到各个车辆领域，几乎可适用于任何尺寸的卡车或乘用车。AAM 最初为皮卡车等后轮驱动 (RWD) 车辆设计了 QUANTUM 轻型整体式车桥，但后来将 QUANTUM 技术扩展到 RWD 和全轮驱动 (AWD) 乘用车、跨界车和 SUV 上。

整体式车桥

QUANTUM 整体式车桥具有可扩展性，可用于重型、中型或轻型后驱皮卡。这种耐用而轻巧的车桥提高了车辆的额定载重。与传统车桥相比，其重量减轻了 35%，效率提高了 30%。

全轮驱动和后轮驱动模块

对于希望在其他车辆领域寻找系统的客户，AAM 开发了 QUANTUM 全轮驱动和后轮驱动模块。在包括乘用车、跨界车和 SUV 在内的典型应用中，可以针对多种配置和尺寸来设计和制造 QUANTUM RWD 和 AWD 模块。这些轻巧高效的模块提供开放式、机械限滑、电子限滑和扭矩矢量分配系统配置，并可配备 AAM 首次面市的 EcoTrac ®可断开式全轮驱动技术。与这些车辆领域的传统车桥相比，QUANTUM 后轮驱动和全轮驱动系统的重量减轻了 25%，效率提高了 30%。QUANTUM 全轮驱动和后轮驱动模块还具有更小的封装尺寸，使客户可以灵活地为其他车辆系统提供空间。

EcoTrac® 可断开式模块

QUANTUM 动力传动系统技术几乎可扩展至任何尺寸的车辆，并且该技术还可与其他 AAM 产品结合使用，以改善车辆性能、燃油经济性和乘客安全性。

当 QUANTUM 与 EcoTrac 一起安装时，可以进一步节省燃油，提高乘客安全性。AAM 的 EcoTrac 全轮驱动可在不需要全驱的情况下仅使用前轮，从而为驾驶员提供全轮驱动车辆的性能以及前轮驱动车辆的燃油经济性。EcoTrac 可以感知何时需要全轮驱动，并自动无缝地接合全轮驱动。当根据道路和天气条件不需要 AWD 时，车辆仅使用其主驱动系统（即前轮）以最大限度地提高燃油效率。与传统的 AWD 系统不同，EcoTrac 在后驱动模组 (RDM) 和取力器 (PTU) 处断开连接，从而使传动轴在断开系统连接时停止旋转。更少的旋转部件意味着更少的燃油消耗和更低的排放。

TracRite® 差速器

可以将 AAM 的 TracRite® 差速器产品组合设计到驱动系统中，以改善牵引力、操控性、稳定性和性能。AAM 的全系列差速器包括开放式、机械限滑、电子差速锁、自动差速锁和电子限滑技术。

Dauch 说：“AAM 的核心使命是传递力量。”“我们使用业界最耐用、最高效且技术最先进的动力传动系统产品来做到这一点。QUANTUM 只是我们迈向未来产品创新的第一步，未来的产品将更轻质、更坚固、更智能，有助于满足我们客户的需求和全球驾驶员的需求。”
