Abstract:
Concerning the automotive transmission, the power loss reduction can be achieved by substituting the tapered roller bearings and reducing operating temperature. With SKF's low friction tapered roller bearings, it is possible to reduce frictional torque by 30% on a manual transmission (MT) with lower fuel consumption and lower operating temperature. Lower fuel consumption and CO₂ emission are both special drivers for transmission's future generation powertrains.This paper presents the results obtained for a MT with the SKF's E2 bearings as a proposal for the current differential bearings.
