Abstract:
Improved fuel economy translates into significant savings over the life of a fleet vehicle. Aside from fuel cost savings, tighter emissions regulations require truck Original Equipment Manufacturers (OEMs) to improve the fuel economy of the products they bring to market. OEMs are dependent on Tier 1 suppliers for many systems which have a direct impact on vehicle fuel efficiency. Tier 1 suppliers are then dependent on sub-suppliers for components which affect the fuel efficiency of the system.Improvements in tapered roller bearing design and technology can significantly improve the fuel efficiency of driveline systems. This paper summarizes the improvement in bearing efficiency by applying advanced design and technology solutions. Analysis was used to predict the affect of design changes, leading to an optimized solution. Testing was performed to verify the improvement in bearing efficiency.
