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.
