Engineered for 6x2 and 4x2 axle configurations, this family of single-reduction, solo drive axles can be customized for vehicle applications with gross combination weight ratings of 32-45 tonnes (70,000-100,000 lbs.).
Now available for pre-production testing, the Spicer global single axle offers increased mechanical efficiency and less weight than current offerings. With improved operating efficiency and a higher payload, production units are scheduled to hit the market in 2018.
The Spicer global single axle has been engineered on a flexible platform that combines design and production efficiency with various application-specific demands. This axle is the first to support ratios lower than 2:1 as part of a range of axle ratios designed for engine downspeeding. This enables efficient operation at desired highway cruise speeds with engine speed approaching 1,000 rpm.
Additionally, the global single axle’s full selection of ratios is the broadest available, supporting up to 6.8:1.
“The regional market needs of today’s global commercial-vehicle manufacturers vary greatly, but Dana offers solutions that are truly localized to meet our customers’ specific requirements,” says Mark Wallace, President of Dana Commercial Vehicle Driveline Technologies. “The Spicer global single axle family delivers the increased efficiency that is required by the industry, along with regional customization that buyers demand. This axle can also be paired with a wide selection of Spicer driveshafts for a fully optimized drivetrain solution.”
The Spicer global single axle’s high-power density bearings reduce friction and spin loss, allowing for a more efficient transfer of power to cover a broad range of duty cycles. Patented lube meter technology ensures optimum lubrication of the bearings, and a Venturi-style cover more efficiently directs lubrication to where it is needed.
Dana also offers a range of fuel-efficient synthetic gear lubricants, such as the Spicer XFE-75W90 axle lubricant, to further improve fuel economy with this drive axle and Dana’s other high-efficiency drivetrain solutions.
Dana will exhibit the Spicer global single axle, along with other drivetrain solutions for the commercial-vehicle industry, in Hall 17, Stand A24 at IAA.
