In a step toward more integrated drivetrains in Kenworth and Peterbilt trucks, Paccar announced a new 40,000-pound tandem axle that saves weight and improves fuel economy.  This axle is “really helping us make steps toward an integrated powertrain” Landon Sproull, Paccar vice-president, told reporters at the American Trucking Associations Management Conference and Exhibition.  The new axle is designed for linehaul, regional haul, and pick-up and delivery customers, reated at 40,000 pounds and supporting a gross combination weight of 80,000 pounds.  It offers ratios from 2.47 to 3.70 with engine torque compatibility up to 1,650 lb-ft and multi-torque ratings compatibility up to 1,750 lb-ft.  The Paccar axle features a pinion-through-shaft design that simplifies power flow in the axle for maximum efficiency.  A laser-welded carrier design eliminates internal fasteners, and reduces oil churn and weight.  Overall the axle offers up to 150 pounds of weight savings, according to Paccar.  Kenworth will begin offering the axle to customers in January 2017.
