里程碑时刻：AAM 推出 TracRite®

AAM 成立于 30 年前，致力于实现质量、技术领先和卓越运营。对技术领先地位的重视使得我们始终致力于寻求为安全、性能和可持续发展设定新基准的工程解决方案。

1996 年，AAM 的高级工程小组开发出一种新产品：TracRite® 牵引力增强型差速器系列，该产品将在未来多年内提高车辆的动力和效率，从而与我们的“技术领先”理念保持一致。

长期以来，标准差速器或开放式差速器一直都是汽车的基本部件，通过让外轮的转动速度略快于内轮的转动速度，从而实现平稳转弯。这种设计最大限度地降低了轮胎噪音，并确保了车辆转弯时的机动性。然而，当遇到结冰或湿滑路面时，这种传统设计的局限性就会暴露出来。在这种情况下，轮胎很容易就会遵循最小阻力原则，从而导致车轮打滑并失去牵引力。

TracRite 化解了这一挑战，并且可以提供多种解决方案，旨在防止电力不成比例地流向最小阻力的轨迹。这些创新的差速器采用了多方面的方法，以增强在恶劣条件下的牵引力。从盘离合器到齿轮系、差速锁、电子差速锁和电子限滑器，TracRite 系列提供了一系列旨在有效分配扭矩、抑制车轮空转和提高整体牵引性能的技术。

经过两年多的开发、测试和验证，#TeamAAM 的工程师们推出了以 TracRite 命名的首批产品：TracRite GT 斜齿轮限滑差速器，适用于 2002 RAM 重型 2500 / 3500 皮卡的 10.5 英寸和 11.5 英寸后桥。AAM 的电子锁定差速器 (TracRite eL) 也在市场上首次亮相，TracRite EL 开放式差速器在前桥上配备了电子锁定功能，而 TracRite GTL 斜齿轮限滑差速器在后车桥上配备了电子锁止功能。

自推出以来，TracRite 和其他 AAM 差速器已申请了 90 多项专利。仅在美国，AAM 就获得了 120 多项该技术的专利，还有多项专利正在申请中。AAM 已在 11 个其他国家申请了 240 多项外国专利，另有 37 项专利申请仍在审批中。

TracRite 早期开发的关键人物并且至今仍在继续“传递力量”的 #TeamAAM 成员包括：创新产品工程总监 Paul Valente、PE 创新执行总监 Jim Downs、齿轮设计与开发产品工程总监 Eric Rivett、测试/验证高级经理 Scott Jacob 以及差速器产品工程高级技术经理 Joe Balenda。

随着技术的不断发展，TracRite 已被广泛应用于 GM、Volkswagen、Stellantis、Ford 和 Mercedes 等领先汽车制造商的各种车辆上。TracRite 已成为提高车辆在各种地形上的性能所不可或缺的组成部分。
