    Abstract: An improved thrust bearing for a turbocharger includes a first bearing surface, a second bearing surface, an internal passageway, a primary pad, and a plurality of secondary pads. The internal passageway fluidly connects the first and second bearing surfaces. The primary pad may be defined on the first bearing surface. The primary pad further defines a first aperture in fluid communication with the internal passageway and an oil feed defined in a turbocharger housing. The plurality of secondary pads may also be defined on the first bearing surface. Each secondary pad in the plurality of secondary pads may include a secondary surface area which is smaller than the primary surface area of the primary pad.

    Abstract: A turbocharger assembly includes a compressor assembly, a turbine wheel, a shaft, a bearing assembly, and a cooling gas conduit. The compressor assembly includes a compressor impeller. The compressor impeller includes an outermost impeller edge and has a maximum cross-sectional dimension at the outermost impeller edge. The shaft interconnects the compressor impeller and the turbine wheel. The bearing assembly surrounds at least a portion of the shaft. The cooling gas conduit is disposed in fluid communication with the compressor assembly and the bearing assembly. At least a portion of the cooling gas conduit is disposed adjacent the outermost impeller edge such that the cooling gas conduit is configured to receive a portion of intake gases flowing along the outermost impeller edge and guide the portion of the intake gases toward the bearing assembly to cool the bearing assembly.

    Abstract: A turbocharger includes a compressor housing, turbine housing, and center housing between the compressor and turbine housings. A turbine wheel is disposed in the turbine housing on a turbine shaft. A compressor wheel having a shank is disposed in the compressor housing on the turbine shaft. The shank has outer and reduced portions. The reduced portion has a smaller diameter than the outer portion. A backplate is mounted to the compressor housing adjacent the compressor wheel and defines a stepped cylindrical bore with a maximum diameter portion and a minimum diameter portion having a smaller diameter than the maximum portion. The outer portion is disposed in the maximum portion. The reduced portion is disposed in the minimum portion. The outer diameter of the shank is greater than or equal to the minimum diameter of the backplate, and the stepped cylindrical bore and the shank define a variable width gap.
