Daimler Trucks launches intelligent truck axle

Daimler Trucks has launched an ‘intelligent’ truck axle geared at reducing fuel consumption by proactively managing lubricant distribution.

Production of the so-called New Final Drive (NFD) axle, which has been designed for the Actros model and is said to be especially lightweight, commenced last week at the Mercedes Benz plant in Kassel, Germany.

“The rear axle reduces fuel consumption of the Mercedes-Benz Actros by up to 0.5 per cent,” Daimler commented.

The design reportedly benefits from an actively controlled oil regulation mechanism, where the oil is supplied “as needed” depending on speed, torque and temperature.

“Intelligent oil management minimises the swirl of liquid in the final drive and thus reduces the friction loss from the gears turning in the oil bath,” Daimler explained.

"The second generation of the Integrated Powertrain from Daimler Trucks – consisting of engine, transmission and axle – has already resulted in fuel savings of up to 6 per cent for the Mercedes Benz Actros and ensures the lowest possible Total Cost of Ownership.

“The world's first intelligent truck axles [now] enable us to reduce fuel consumption by a further 0.5 per cent,” the OEM summarised.

As part of Daimler Trucks’ platform strategy, the new truck axle will be produced at the Mercedes Benz plant in Kassel and the US site in Detroit.
