AAM 的 TracRite 差速器有助于提高电动汽车的性能和舒适性

美国车桥制造有限公司的 TracRite® 差速器产品组合有助于提高电动汽车（包括皮卡车和 SUV）的舒适度和性能。

与传统动力系统一样，许多电动汽车使用单个电机在车轴上驱动两个车轮。AAM 的 TracRite 差速器可高效地将电驱动电机产生的功率分配到左右车轮上。作为关键车辆系统，AAM 的行业领先技术还提供了额外的功能，为这一不断增长的车辆细分市场增添性能并改善乘客体验。

AAM 工程副总裁 Craig Renneker 表示：“电动汽车可以给包括差速器在内的车辆系统带来独特的设计挑战。”“AAM 在设计、工程和制造任何车型的各种差速器方面处于领先地位。我们拥有开发在几个关键领域提供无与伦比性能的技术的专业知识：牵引力、NVH 和最大化再生扭矩。”

随着全球汽车制造商将电动机的使用扩展到其车辆范围，性能和舒适性变得越来越重要。大多数汽车制造商已经宣布未来的电动皮卡和/或 SUV 具有越野或牵引能力。牵引增强差速器，如 AAM 产品组合中的差速器，将用于最大限度地提高这些车辆的车辆性能。

AAM 在减少动力传动系统噪声、振动和粗糙度 (NVH) 方面的悠久历史和专业知识，使 AAM 能够设计和制造几乎不会产生可感知噪声的差速器。凭借电动汽车的安静特征，这可以提高乘客的舒适性，为他们带来更安静的驾驶体验。

此外，AAM 久经考验的坚固齿轮和差速器设计旨在优化制动期间从道路到电机的扭矩反向传动，这便可以在车辆行驶时为电池充电，从而增加车辆行驶里程。

AAM 的 TracRite 差速器系列通过各种选项提供改进的车辆牵引力、操控性、稳定性、性能和成本竞争力的垂直整合，这些选项包括：

TracRite 开口 – AAM 的标准差速器可在左右车轮之间实现安静且经济高效的扭矩分离。

TracRite PC 盘离合器 - X 限滑差，可增加摩擦板以提供阻力，这有助于在每一侧的牵引力或轮胎装载不同时稳定车轮速度。

TracRite GT 齿轮传动链 - AAM 的重型限滑，使用一套可调谐的螺旋齿轮，在每一侧的牵引力或轮胎装载不同时提供阻力。

TracRite EL 开口 + 电动锁 - 此差速器能够针对大多数驾驶条件打开差速器，具有电子可选择的锁功能，可在介入时完全同步每一侧的车轮速度，实现越野性能。

TracRite AL 自动锁 - TracRite EL 功能，但基于车辆传感器和条件的自动锁介入，无需驾驶员输入差速器锁介入

TracRite GTL 齿轮系锁 - 该技术具有与 TracRite EL 汽车锁相同的功能，但当锁未介入时螺旋限滑。

TracRite eLS 电子限滑 - 完全电子控制的限滑提供零到最大离合器容量。该技术可针对各种牵引力和摇曳阻尼性能优势进行调整。

  • 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;
