Dana Holding Corp. has introduced a new driveshaft specifically engineered to further support truck engine downspeeding. Dana’s next-generation driveshaft weighs 30 pounds less than existing products and is tailored to address the specific torque-management strategies of individual commercial-vehicle manufacturers.
Engineered with fewer components, this next-generation driveshaft offers a simplified installation process to reduce assembly costs for original-equipment manufacturers (OEMs) and improve ease of maintenance for truck owners.
Performance and vehicle dynamics are improved with reduced noise, vibration and harshness levels, which can also extend component life. Available now for pre- production evaluation by OEMs, Dana’s latest innovation is designed for severe- duty, long-haul applications on high-efficiency Class 8 trucks.
This driveshaft is ready for powertrains of the future that will be engineered for further engine downspeeding — enabling an axle ratio lower than 2.26:1, which is the fastest ratio on the market today.
Dana was the first to offer a driveline solution for engine downspeeding with the introduction two years ago of the Spicer AdvanTEK 40 tandem axle, SPL 350 driveshaft, and SPL 250 inter-axle shaft. Together, this system can handle 30 percent higher input torque from downsped engines, and it enables increased overall vehicle efficiency of more than 2 percent when compared with competitors’ offerings.
