Cummins, Eaton boost torque in integrated powertrain



NASHVILLE, Tenn. — Eaton and Cummins have developed a new integrated powertrain that will offer efficiency benefits to carriers hauling heavy payloads.

Cummins ISX15 engines rated at 400-475 hp and mated to Eaton automated transmissions now produce 1,850 lb.-ft. of torque, up from 1,750 lb.-ft. previously.

The higher torque output Cummins/Eaton powertrain is approved for gross combination weight (GCW) ratings of up to 140,000 lbs.

The Fuller Advantage C-Ratio 10-speed is available for GCWs of up to 110,000 lbs and the UltraShift Plus MHP 13-speed is available for applications with GCWs of up to 140,000 lbs. The UltraShift Plus MXP 18-speed is also available and it has no GCW limit. Cummins and Eaton announced the new torque rating at the Technology & Maintenance Council’s spring meetings.

The companies also said they’re working on a new SmartAdvantage series transmission that will be optimized for the 1,850 lb.-ft. rating. It’ll be limited to a GCW rating of 80,000 lbs and will be available in August.

“This new rating is an ideal solution for performance-minded fleets,” said Ryan Trzybinski, product strategy manager, commercial powertrain, Eaton. “This also provides a huge upside for customers in the vehicle’s resale value.”

The added torque will be ideal for long combination vehicle (LCV) applications in Canada, or others in which additional torque is needed. It also extends SmartTorque2 to the lower gears – or merge gears – Trzybinski said, giving drivers more torque when accelerating.

Eaton also announced at TMC its new GearLogic technology, which has been integrated with Cummins’ ADEPT electronic features. GearLogic allows for the smooth delivery of features such as Hill Start Aid, engine overspeed protection, enhanced engine braking, Smart Coast, Blended Pedal, and Vehicle Acceleration Management, the companies announced.

“We continue to develop and commercialize new technologies to enhance the benefits of an Eaton/Cummins powertrain,” Trzybinski said. “This latest integration of electronics and advanced technology features provides our customers with more choices to meet their unique needs and preferences.”

The two companies also announced they are working more collaboratively to support customers. The Cummins Care and Eaton Roadranger support programs now offer integrated call centers and the sharing of diagnostic tools. Both companies will also cross-train their sales and service teams to support both product lines.

Cummins and Eaton also added new tools to their shared SmartAdvantagePowertrain.com Web site, including a questionnaire that helps point customers towards the most appropriate SmartAdvantage powertrain for their application.

Eaton also announced its Procision medium-duty dual clutch transmission is now in production and available in International and Freightliner trucks.
