Lightweight Dana driveshafts for commercial vehicles up to class 6Spicer Formed Aluminum Tube Driveshaft
Dana used the IAA Commercial Vehicles Show in Germany to unveil the Spicer Formed Aluminum Tube Driveshaft. Designed for medium-sized pickups and light commercial vehicles up to class 6, it’s a single-piece assembly with reduced weight and increased assembly clearance when compared to a traditional two-piece steel driveshaft.
Available in the summer of 2013 as an option for Spicer Life Series driveshafts in North America, the new product is said to weigh up to 25% less than two-piece steel assemblies.
Starting with a straight tube, it’s shaped to have an expanded center using a proprietary hydroforming manufacturing process. This expanded center allows it to run at higher speeds for a given length, Dana explains, while offering increased strength and up to a 5% reduction in weight over straight aluminum tube driveshaft designs.
Because the driveshaft consists of a single piece, vehicle responsiveness is said to be improved. By eliminating the center bearing required in a two-piece assembly, noise and vibration are reduced.
