Fuel-efficient Tapered Roller Bearings for Axles in Off-road Vehicles
- 2 Downloads
The objective of a research project with various project partners was to reduce friction losses in the axle of off-road vehicles by 50 %. Using newly developed fuel-efficient tapered roller bearings from Timken as part of a package for the efficient axle design, this goal was not only met, but exceeded.
Minimizing Friction Losses
In order to increase the efficiency of off-road vehicle axles, their friction loss must be reduced. As part of a research project, a heavy-duty truck axle was tested on a test rig for efficiency across the operating speed and torque range. A project partner then set out to redesign the axle to improve the efficiency. Timken developed and tested fuel-saving tapered roller bearings of the type FE (Fuel-efficient) for this axle.
