Abstract
A turbocharger thrust bearing assembly, which maintains a constant relationship between the thrust faces, for example by use of gimbal or spherical segment geometry. Spherical geometry, while more difficult to manufacture than that of a flat thrust bearing, provides a more constant relationship between the thrust pads and thrust washers than is possible with a typical flat thrust bearing. As a consequence of this more constant relationship the thrust bearing operates with less oil flow, which ultimately may reduce vehicle emissions.
