Abstract

A turbocharger is provided including a turbine wheel and a compressor wheel attached to one another by a shaft. A thrust plate includes a plate body having an aperture there through and defining a plurality of circumferentially spaced pad regions that define a land region that is perpendicular to a rotational axis of the shaft. The plate body further defines a plurality of two stage slope regions adjacent to each of the land regions. The two stage slope regions include a steep slope portion and a gradual slope portion disposed between the steep slope portion and the land regions. The rotary assembly of the turbocharger includes a thrust surface that engages the pad regions. The two-stage slope regions provide improved loading capacity by the combination of better lubricant oil availability due to the steep slope region and optimized tribological performance due to the gradual slope region.

Description

technical field [0001] The present disclosure relates to turbocharged internal combustion engines, and more particularly to improved thrust bearing designs for improved lubrication. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Internal combustion engines are used to generate appreciable levels of power on a reliable basis for extended periods of time. Many of these engine components employ a boosting device, such as an exhaust gas turbine-driven turbocharger, to compress the airflow before it enters the engine's intake manifold to increase power and efficiency. [0004] Specifically, turbochargers use centrifugal gas compressors that force more air, and thus oxygen, into the engine's combustion chamber than would otherwise be achievable with ambient atmospheric pressure. The additional mass of oxygenated air forced into the engine improves the engine's volumetric ef...
