Abstract
An oil-lubricated, tapered-land thrust bearing assembly (60) for automotive turbochargers (10) including a thrust bearing (30). The thrust bearing (30) includes an assembly of a base (62) with at least one insert (64 or 66), which is designed to control the oil film as a purposefully compliant structure based on applied force to optimize performance at low and high power operation. The ramp angle is relatively large at a low load and decreases to a smaller ramp angle at higher loads. On one side of the turbocharger (10), the thrust bearing assembly (60) may operate with a flinger sleeve (34) and a thrust washer (24) within a complementary bearing housing cover (32).
