The Endurant 12-speed automated transmission, the primary product from Eaton and Cummins’ three way partnership, has been named commonplace tools on Worldwide LT Collection, RH Collection, and LoneStar heavy-duty vehicles.
Made out there on Worldwide LoneStar and LT vehicles spec’d with Cummins’ X15 engine in Could final yr, Tuesday’s announcement provides protection for Worldwide’s A26 engine together with the regional RH tractor.
The primary “objective constructed” heavy-duty automated transmission available on the market when it debuted in 2017, Endurant options torque rankings of as much as 1,850 lb.-ft.
Automated handbook transmissions (AMT) are bred from a handbook gearbox. Although the method of shifting is automated, the shift sample isn’t modified.
With a real automated transmission just like the Endurant, Eaton’s Supervisor of Program Administration Matt Erdmann informed me throughout a check drive forward of Endurant’s debut in 2017, that many typical design restraints have been eliminated. For instance, Endurant options linear shift rails – a departure from the usual sideways shift sample required of handbook transmissions and AMTs. Linear shift rails additionally assist optimize the design for pace and reliability since there’s no wasted sideways movement.
