Cummins will offer an 18-speed version of its Endurant automated transmission as an option or X15 diesel engines beginning next year.
Cummins said it has developed what it called the “next-generation of integrated power” for high-horsepower applications – an Endurant XD 18-speed transmission option for its X15 Performance Series engines, beginning in 2021.
The X15 Performance Series and Endurant XD powertrain is optimized for high gross combined weight on-highway and severe on and off highway applications such as dump and logging trucks, with full application coverage to be announced at a later date, according to Cummins.
Available starting in 2021, the Cummins X15 and Endurant XD is currently going through extensive field tests and validation.
“The newest integrated powertrain from Eaton Cummins Automated Transmissions Technologies delivers a versatile powertrain, gives professional operators tailored configurations that meet their needs, and allows the newest drivers to simply get in and go,” said J. Michael Taylor, general manager, global powertrain integration, Cummins. “The Eaton Cummins Automated Transmissions Technologies develops products with the proven process of deeply integrated customer councils, which provides key insights, input, and feedback.”
The Endurant XD automated transmission features 18 forward speeds and up to six reverse speeds. A high-capacity bottom 8-bolt and rear power take-off provisions are offered as standard equipment, providing customers with flexibility for final equipment design and the ability to power necessary accessories. A transmission oil cooler provision is available when required.
When combined with the X15 Performance Series, the toughest applications and duty cycles can now benefit from a truly integrated automated powertrain. With the strongest engine brake in the industry, the new 18-speed powertrain will reduce the amount of stress placed on service brakes.
