Abstract
To save energy and to reduce weight of automobiles, the tribological behaviour of the bearing positions in the torque flow between drive motor and tyre contact have been optimized to reduce losses in rolling bearings. This has resulted in a considerable increase in power density and life of rolling bearings in gearboxes and differential gears. By development of a new generation of wheel bearings it has been possible to reduce the weight of unsprung masses of the cars considerably. By selection of suitable lubricants, frictional losses in rolling bearings can also be reduced. By means of a short test it is now possible to evaluate the behaviour of lubricants in the rolling contact under operating conditions.
