Ultimate Efficiency: The New DT12-HE

The Detroit® DT12® HE transmission is an all-new, 对于那些希望尽可能减少燃料消耗的客户来说，这是一个非常有效的选择. DT12-HE专为那些对变速箱性能要求极高的客户而设计. Design enhancements include:

Integrated Detroit Powertrain

ONLY ONE COMPANY CAN DELIVER THIS LEVEL OF INTEGRATION

The Integrated Detroit® Powertrain为您提供高效运营业务所需的性能和可靠性. Detroit has designed, engineered and manufactured the engine, transmission and axles to work together seamlessly, providing the optimal powertrain solution for your business needs. The Integrated Detroit Powertrain is available in the Freightliner Cascadia.

Transmission

  • Integrated Communications Benefits: The DT12® transmission links engine to axles, and communicates with the DD13® Gen 5 and DD15® 第5代采用集成电子网络，共享减少损坏的信息，如离合器过载和传动系统保护.
  • Super-Finished Gears: 紧密间隔的12速齿轮，现在与“超级完成”齿轮在新的DT12® available for the Cascadia, improves low-speed maneuverability, making the Detroit Powertrain not only strong and efficient, but also smooth and safe to operate as well.
  • Intelligent Powertrain Management (IPM): DT12使用GPSbbin捕鱼游戏平台和地形图信息来操纵发动机和传动功能, taking advantage of the truck's surroundings. IPM6 refines the parameters of this technology, making the truck even more capable of utilizing its surroundings efficiently.
  • Transmission Benefits: The DT12's direct drive and over drive gearing, along with eCoast, 与减速发动机集成在一起，现在在关闭油门时怠速低于500RPM，以优化燃油经济性.

 

Engine

  • Engine Compliance: Detroit provides a wide range of new vehicle engines compliant with EPA, CARB emissions, GHG, and OBD requirements. 请咨询您当地的经销商，以确保选择的产品符合您的具体需求.
  • Downsped Engines = Improved Fuel Economy: DD13和DD15的降速为400马力，额定转速为1750磅/英尺，在较低的rpm下可以提供更大的马力和扭矩, 保持你的卡车在最高档位更长时间，同时巡航更有效的发动机速度. 较低的发动机转速减少了燃油喷射次数，显著提高了燃油经济性.
  • Six-Blade Engine Fan: The six-blade fan reduces power draw without sacrificing cooling capabilities.

Steer Axle

  • Numerous Steer Axle Advantages: Detroit steer axles offer rugged strength in a lightweight package, and integrate optimally with the other components. They are designed for the life of the axle, with multiple ratings available for tailored weight distribution.
  • Superior Maneuverability: bbin电竞游戏动力系统的最先进的转向轴提供了一个55度的车轮切割非常灵活的机动. 
  • Needle Bearings Improve Durability: With needle bearings instead of bushings, they won't damage the king pins, and offer increased durability.

Tandem Rear Axle

  • New Axles Designed for Fuel Economy: To provide optimum efficiency and performance, bbin电竞游戏动力系统包括一个全新的轴，专门设计与减速DD13集成® Gen 5, DD15® Gen 5 and DT12®, resulting in rock-solid reliability and durability.
  • Faster 6x4 Axle Ratios: 6x4配置可用于需要四轮驱动和卓越牵引力的应用. A variety of faster axle ratios are available, ranging from 2.41 to 2.28.
  • Faster 6x2 Axle Ratios: The 6x2 configuration boasts a 2.28比，允许DD15第5代转向更低的rpm与卡车巡航在相同的速度. It pairs perfectly with the low RPM torque curve and direct drive transmission. This means it can cruise in top gear longer, for better fuel efficiency.
  • Lighter 6x2 Axle: The 6x2 axle configuration incorporates a non-driven tag axle on the tandem, reducing total weight (by 380 lbs) and the number of moving parts, delivering better fuel economy.
  • New Optional Axle Lubrication Management (ALM): 串联后桥具有可选的轴润滑管理(ALM)系统，可主动调节环形齿轮和摩擦损失优化的小齿轮轴承的油位，以减少摩擦和寄生损失, extending gear life and further improving fuel efficiency.

 

Aftertreatment

  • 1-Box®: 1-Box是一个完整的后处理排放系统，结合了SCR催化剂, the Diesel Oxidation Catalyst (DOC), 柴油微粒过滤器(DPF)和柴油排气液(DEF)都成一个简单的组件.

The AMT Difference

 自动手动变速器(AMT)具有手动变速器和自动变速器的优点. Its design uses an efficient clutch instead of a torque converter, but the clutch and shifting are handled by a computer-controlled air system. 即使是一个新手司机也可以用最少的精力和燃料来工作，而且效率最高.

The DT12® 公路系列变速箱提供12速，以提高效率和灵活性. 它的双踏板设计使驾驶员能够将注意力集中在前方而不是脚下, increasing safety and productivity. As a bonus, seamless integration with Detroit® engines and safety systems promotes optimal performance.

eCoast

当车辆滑行时，变速器自动断开，以帮助最大限度地节省燃料.

Skip Shift

传输控制模块(TCM)发送电子命令来“跳过”不必要的档位, helping increase acceleration to achieve cruising speed quickly and smoothly, 并允许驾驶员根据负载和坡度在适当的“启动档位”加速.

Powertrain Communication

通用动力系统控制器(CPC)优化了电机控制模块和传输控制模块之间的高速通信, improving operational efficiency throughout the entire powertrain.

Active Driveline Protection

变速器控制模块(TCM)计算传动系统中的扭矩，并与发动机扭矩控制进行调节，以提高驾驶舒适性，减少传动系统磨损.

Intelligent Powertrain Management

智能动力系统管理系统(IPM)可以精确定位卡车的位置，并提前一英里预测地形. IPM will adjust cruise control, pre-select gears, 减速和刹车，以最大限度地提高效率，以适应前方的路况.

Total Weight

The aluminum housing and single countershaft help save weight, allowing for even more payload efficiency, while still offering excellent durability.

Power Take-Off

DT12® 变速箱配有专有的后置动力起飞(PTO)，可允许散装牵引车/拖车市场的客户使用液体拖车操作应用, dry goods, wet goods, and moving floors.
