Meritor’s new 14XE HE high-efficiency linehaul tandem drive axle has shed 30 pounds from existing 14X models, and improved efficiency by 1.5%.
It comes with high-efficeincy bearings, the Meritor Lube Management system, precision-finished gearing, and ratios as low as 2.15 for aggressive downspeeding.
“Based on today’s diesel prices, a fleet with 1,000 trucks equipped with the 14X HE could realize US $1 million per year in fuel savings,” said Ken Hogan, vice president – rear drivetrain.
Many improvements were realized using laser welding to manufacture components. The axle’s ring gear is also laser-welded to the differential housing, creating a joint that eliminates fasteners and reduces oil churning losses, the company says.
