DT12公路系列:自动手动变速器

Transmission

Engine

• Engine Compliance: bbin电竞游戏提供了一系列符合EPA标准的新型汽车发动机, CARB emissions, GHG, and OBD requirements. Please consult your local dealer to ensure the selection of a product that meets your specific needs.
• 减速发动机=提高燃油经济性 The DD13 and DD15 with downsped 400 HP and 1750 lb/ft rating deliver greater horsepower and torque at lower RPMs, keeping your truck in top gear longer while cruising at more efficient engine speeds. Lower engine speeds reduce the number of fuel injections, dramatically improving fuel economy.
• Six-Blade Engine Fan: 六叶风扇在不牺牲冷却能力的情况下降低了功耗.

Steer Axle

• Numerous Steer Axle Advantages: bbin电竞游戏转向轴提供坚固的强度在一个轻量级的包, 并与其他组件进行最佳集成. 它们是为车轴的寿命而设计的, 具有多个额定值可用于量身定制的重量分布.
• Superior Maneuverability: The Detroit Powertrain's state-of-the-art steer axles provide a 55-degree wheel cut for remarkably nimble maneuvering. 
• 滚针轴承提高耐用性: 用针轴承代替衬套, they won't damage the king pins, and offer increased durability.

Tandem Rear Axle

• 新型节油车轴: 提供最佳的效率和性能, the Detroit Powertrain includes an all-new axle specifically designed to integrate with the downsped DD13^® Gen 5, DD15^® Gen 5 and DT12^®，从而产生坚如磐石的可靠性和耐用性.
• Faster 6x4 Axle Ratios: The 6x4 configuration is available for applications requiring 4-wheel drive and superior traction. 各种更快的轴比是可用的，从2.41 to 2.28.
• Faster 6x2 Axle Ratios: 6x2配置拥有一个2.28 ratio, allowing the DD15 Gen 5  to turn lower RPMs with the truck cruising at the same speed. 它与低RPM扭矩曲线和直接驱动传动完美搭配. 这意味着它可以在最高档位巡航更长时间，以获得更好的燃油效率.
• Lighter 6x2 Axle: 6x2轴配置在串联上包含一个非驱动标签轴, 减少总重量(380磅)和活动部件的数量, delivering better fuel economy.
• 新的可选轴润滑管理(ALM): The tandem rear axles feature an optional axle lubrication management (ALM) system that actively regulates the oil level at the ring gear and friction-loss optimized pinion bearings to reduce friction and parasitic loss, 延长齿轮寿命，进一步提高燃油效率.

Aftertreatment

• 1-Box^®: The 1-Box is a complete aftertreatment emissions system that combines the SCR catalyst, 柴油氧化催化剂, Diesel Particulate Filter (DPF) and Diesel Exhaust Fluid (DEF) all into one simple component.

eCoast

Transmission automatically disengages when the vehicle is coasting to help maximize fuel economy.

Skip Shift

The Transmission Control Module (TCM) sends electronic commands to “skip” unnecessary gears, 帮助增加加速，达到巡航速度快速，平稳, and allowing the driver to accelerate in the appropriate “start gear” based on load and grade.

Powertrain Communication

A Common Powertrain Controller (CPC) optimizes high-speed communication between the Motor Control Module and the Transmission Control Module, 提高整个动力系统的运行效率.

Active Driveline Protection

The Transmission Control Module (TCM) calculates the torque wind-up in the driveline and regulates with engine torque control for enhanced driving comfort and less driveline wear.

智能动力总成管理

智能动力总成管理 (IPM) pinpoints the truck's location and looks over a mile ahead to anticipate terrain. IPM will adjust cruise control, pre-select gears, eCoast and brake the engine to maximize efficiency into the road conditions ahead.

Total Weight

铝制外壳和单副轴有助于减轻重量, 允许更高的有效载荷效率, 同时仍然提供出色的耐用性.

Power Take-Off

DT12^® transmissions are available with a proprietary rear-mount-only Power Take-Off (PTO) that may allow customers in the bulk-haul tractor/trailer market to operate applications using liquid trailers, dry goods, wet goods, and moving floors.
