你知道公认最耐用的“AT变速箱”是哪三款吗？

　　Do you know which three are recognized as the most durable "AT transmissions"?

　　在汽车自动变速箱中，AT变速箱凭借其卓越的性能和可靠的品质，赢得了广泛车主的肯定与赞誉。根据各大汽车网站及车主的真实反馈，公认最耐用的三款AT变速箱分别是：采埃孚8AT、爱信6AT及马自达6AT。

　　In automatic transmissions for automobiles, AT transmissions have won widespread recognition and praise from car owners for their outstanding performance and reliable quality. According to major automotive websites and feedback from car owners, the three most durable AT transmissions are recognized as the ZF 8-speed automatic transmission, Aisin 6-speed automatic transmission, and Mazda 6-speed automatic transmission.

　　采埃孚8AT

　　ZF 8AT

　　采埃孚8AT凭借0.1秒极限换挡速度、高扭矩承载能力被豪华汽车品牌广泛应用，故障率低至0.78%，耐用性与性能兼备?。采埃孚8AT四个行星齿轮组和五个离合器的设计，实现了8个前进挡位和2个倒挡位，换挡平稳迅速。多级跳挡功能的引入，进一步提升了换挡的效率和灵活性；节油降耗，通过降低发动机转速，相同行驶条件下，与6挡自动变速箱相比，油耗可降低约6%，启停系统和滑行模式等智能节能技术的加入，进一步降低了燃油消耗和排放。ZF（采埃孚）的8AT变速箱和宝马的多款经典发动机匹配性极高，可靠、平顺、加速响应都能体现一台宝马汽车该有的运动水平。特别是换挡速度快、干脆，而且发动机转速提升起伏有序。

　　The ZF 8AT is widely used by luxury car brands due to its extreme shifting speed of 0.1 seconds and high torque carrying capacity, with a failure rate as low as 0.78%. It has both durability and performance?. The design of the ZF 8AT with four planetary gear sets and five clutches enables 8 forward gears and 2 reverse gears, ensuring smooth and rapid shifting. The introduction of multi-level gear shifting function further enhances the efficiency and flexibility of gear shifting; By reducing engine speed, fuel consumption can be reduced by about 6% compared to a 6-speed automatic transmission under the same driving conditions. The addition of intelligent energy-saving technologies such as start stop system and coasting mode further reduces fuel consumption and emissions. ZF's 8-speed automatic transmission matches BMW's classic engines with high reliability, smoothness, and acceleration response, all of which reflect the level of sportiness that a BMW car should have. Especially the shifting speed is fast and crisp, and the engine speed increases in an orderly manner.

　　采埃孚8AT变速箱耐用性据称可达到100万公里以上，成为汽车界最耐用的变速箱之一。

　　The durability of the ZF 8-speed automatic transmission is said to reach over 1 million kilometers, making it one of the most durable transmissions in the automotive industry.

　　爱信6AT

　　Aisin 6AT

　　以极低故障率（约0.23%–0.8%）和高装机量著称，广泛用于日系、德系、美系等家用车，被多次称为“耐用标杆”?。爱信6AT采用莱佩莱捷式行星齿轮组结构，通过五组离合器与制动器的精密配合实现换挡平顺，齿轮渗碳淬火工艺让齿面硬度达62HRC、寿命延长3倍，独立油冷循环更能将拥堵路况油温稳定在85℃以下，避免高温导致的密封件老化或齿轮磨损。燃油经济性是爱信6AT的另一大优势。它通过两套行星齿轮的协同工作，在升档过程中优化动力传递路径，配合扩大的锁止范围，让发动机更多时间处于高效运转区间；全新高效节能阀与电控泵的组合，使燃油效率提升9%，尤其在起步或怠速等传统变速箱油耗较高的场景下，能更合理地调节燃油喷射量，兼顾动力输出与节能需求。

　　Known for its extremely low failure rate (about 0.23% -0.8%) and high installed capacity, it is widely used in Japanese, German, American and other family cars and has been repeatedly referred to as the "durability benchmark"?. The Aisin 6AT adopts the Lepelejie planetary gear set structure, which achieves smooth shifting through precise coordination of five clutches and brakes. The gear carburizing and quenching process makes the tooth surface hardness reach 62HRC and extends the service life by three times. The independent oil cooling cycle can stabilize the oil temperature in congested road conditions below 85 ℃, avoiding seal aging or gear wear caused by high temperature. Fuel economy is another major advantage of the Aisin 6AT. It optimizes the power transmission path during upshifting through the coordinated work of two sets of planetary gears, and with the expanded locking range, allows the engine to operate more efficiently for more time; The combination of a new high-efficiency energy-saving valve and an electronic control pump improves fuel efficiency by 9%, especially in scenarios where traditional transmissions have high fuel consumption such as starting or idling, allowing for more reasonable adjustment of fuel injection quantity while balancing power output and energy-saving needs.

　　马自达6AT?虽然马自达从2010年才实现变速箱自主研发，但“创驰蓝天-DRIVE”6AT变速箱通过全速域锁止、高强度材料和精准调校，实现低故障率与高平顺性，实测寿命可达60万公里以上?，成为公认的三大耐用变速箱之一。

　　Mazda 6 AT? Although Mazda only achieved independent transmission research and development in 2010, the "Chuangchi Blue Sky DRIVE" 6-speed automatic transmission achieves low failure rate and high smoothness through full range locking, high-strength materials, and precise tuning, with a tested lifespan of over 600000 kilometers? Becoming one of the three recognized durable gearboxes.

　　传统的AT变速箱液力变矩器仅在高速时锁止，而创驰蓝天-DRIVE技术的锁止范围则覆盖了80-90%的工况，其传动效率几乎接近手动变速箱，从而显著降低了油耗。与采埃孚8AT变速箱一样，马自达6AT变速箱也采用了启停系统和滑行模式等节能技术，进一步提升了燃油效率和减排效果。

　　The traditional AT gearbox hydraulic torque converter only locks up at high speeds, while the locking range of the SkyActiv DRIVE technology covers 80-90% of operating conditions, and its transmission efficiency is almost close to that of a manual gearbox, significantly reducing fuel consumption. Like the ZF 8-speed automatic transmission, the Mazda 6 AT transmission also adopts energy-saving technologies such as start stop system and coasting mode, further improving fuel efficiency and emission reduction effect.

　　尽管早期部分车型曾使用爱信或福特的变速箱，但自“创驰蓝天”技术平台推出以来，马自达坚持自主研发路线，其6AT已广泛应用于昂克赛拉、阿特兹、CX-5等主力车型，形成了鲜明的技术标签。

　　Although some early models used transmissions from Aisin or Ford, Mazda has adhered to its independent research and development route since the launch of the "SkyActiv" technology platform. Its 6-speed automatic transmission has been widely used in major models such as the Axela, Atz, CX-5, forming a distinct technical label.

　　总之，在这个汽车工业繁荣的时代，变速箱作为车辆的核心部件之一，发挥着不可或缺的作用。以上三款AT变速箱代表了不同车企的技术实力，在耐用度、换挡迅速、燃油经济性等方面都有着出色的表现，为车主提供了更好的驾驶体验。

　　In this prosperous era of the automotive industry, the gearbox, as one of the core components of vehicles, plays an indispensable role. The above three AT transmissions represent the technological strength of different car companies, with excellent performance in durability, quick shifting, fuel economy, and other aspects, providing car owners with a better driving experience.
