DAIM­LER TRUCKS has an­nounced a new, ‘in­tel­li­gent’ truck axle that aims to re­sult in im­proved fuel ef­fi­ciency across the Mercedes-Benz Ac­tros range.

The New Fi­nal Drive (NFD) rear axle is ex­tra lightweight and re­duces fuel con­sump­tion in Ac­tros mod­els by up to 0.5 per cent by proac­tively man­ag­ing lu­bri­cant dis­tri­bu­tion, Daim­ler states.

The “ac­tively con­trolled oil reg­u­la­tion” mech­a­nism al­lows oil to be supplied as needed based 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 notes.

Global pow­er­train and man­u­fac­tur­ing en­gi­neer­ing trucks head Frank Rein­t­jes says the ben­e­fits of­fered by the new axle demon­strate Daim­ler’s mas­tery in fuel ef­fi­ciency tech­nol­ogy.

“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 MercedesBenz Ac­tros and en­sures the low­est pos­si­ble to­tal cost of own­er­ship,” Rein­t­jes says.

“The world’s first in­tel­li­gent truck axles even en­able us to re­duce fuel con­sump­tion by a fur­ther 0.5 per cent.

“This once again demon­strates our tech­nol­ogy lead­er­ship and di­rectly pays off for our cus­tomers.”

The new axle will be man­u­fac­tured at the Mercedes Benz plant in Kas­sel (Ger­many) and Detroit (United States).
