Freightliner debuts AMT3 transmission
Jan 1, 2012 12:00 PM
Freightliner Trucks has introduced its AMT3 automated-manual transmission for Business Class M2 vehicles.
The new transmission technology combines design principles of a manual transmission with intelligent electronics to form an automated two-pedal shift system that equalizes driver performance and improves fuel economy.
Unlike automatic transmissions, the AMT3 eliminates the torque converter and instead couples the engine to the transmission with a hydraulically actuated clutch. This clutch actuation results in minimal torque interrupt during acceleration and shifting, while providing constant lock-up.
Clutch control and gear shifts are managed by the Transmission Control Unit (TCU). The TCU's intelligent shift logic evaluates road, grade, and load conditions to perform shifts at optimal engine rpms, resulting in fast and smooth shifting and significant fuel savings.
The AMT3's smooth clutch actuation reduces wear for greater longevity, eliminating the need to replace the clutch virtually over the lifetime of the truck. Lightweight materials such as an aluminum housing increase freight efficiency, and durable components such as heat-treated steel alloy gears and sealed bearings are built to last the life of the truck.
Suitable for pick-up and delivery, such as food and beverage distribution, utility, and towing applications, the AMT3 is available to order for Freightliner Class 6 and 7 trucks in the United States and Canada.
