Abstract: Methods for manufacturing an impeller wheel assembly (e.g., an impeller wheel attached to one or more additional components) are provided. In one example, a method includes casting an impeller wheel without a hub feature in a mold and holding the cast impeller wheel in a fixed position using a holding plate during subsequent stages of fabrication (e.g., the addition of a shaft via friction welding).

Abstract: A turbine assembly and turbocharger containing the same are disclosed. Such an assembly can include a turbine housing for a turbocharger having an inlet portion, a central portion, and a hollow cylindrical portion defining a hollow passageway and an outlet. The inlet portion, central portion, and hollow cylindrical portion are in fluid connection with one another which allows a fluid to enter and pass through the inlet portion to the central portion, pass through the central portion to the hollow passageway, and pass through the hollow passageway to exit the turbine housing through the outlet. The assembly also includes a containment assembly at least partially disposed in the hollow passageway of the hollow cylindrical portion.

Abstract: An assembly for a turbocharger and methods for creating the same are disclosed. Such assembly for a turbocharger includes a bearing housing having first and second bore ends, a housing cavity, and a bearing assembly disposed within the housing cavity. The bearing assembly includes an annular rotating journal positioned at the first bore end and first and second angular contact bearings positioned at the second bore end, where the first and second angular contact bearings resist axial loads in opposite directions. The bearing housing and bearing assembly are configured to receive a shaft and together dampen axial and radial loads in all directions from the shaft.

Abstract: An assembly for a turbocharger and a method of assembling a turbocharger are disclosed. Such an assembly can include an elongate pin having a tapered part and a protrusion at one end of the pin. The elongate pin is configured to be inserted within a housing opening and a cartridge opening such that the taper of the body portion of the pin mates with the taper of the housing opening. The cartridge opening is configured as to mate with the pin such that the pin substantially restricts the bearing cartridge from surging and rolling but substantially permits all other movements of the bearing cartridge.
