Abstract
The present disclosure provides flanged joint or interface between two passageways. The flanged joint includes a first passageway, a connector, and a second passageway. The first passageway may, but not necessarily, be formed via casting process wherein an integrated flange may be defined at the opening of the first passageway such that the integrated flange defines a recess. The connector includes a support body having a fastener region at an upper end of the support body and a flange region at a lower end of the support body. The support body defines an aperture which is configured to support the second passageway. The flange region defined in connector is configured to engage with a recess defined in the first passageway.
Claims19
A nested flanged joint comprising:
- a support body defining an aperture configured to support a second passageway;
- a fastener region defining an angled fastener aperture at an upper end of the support body;
- and
- a flange region defined at a lower end of the support body wherein the flange region is configured to engage with a recess defined in a first passageway.
A turbocharger assembly for a vehicle comprising:
- a turbocharger housing including a compressor inlet and a turbine outlet defining a recess;
- a bore defined by the turbocharger housing,
- a journal bearing disposed within the bore;
- and
- a rotating assembly having a shaft with a turbine wheel on a first end of the shaft and a compressor wheel on a second end of the shaft, the shaft being supported by the journal bearing for rotation within the bore about a longitudinal axis;
- a connector affixed to the turbocharger housing, the connector defining a flange region disposed in the recess;
- and
- an exhaust pipe coupled to the turbocharger housing via the connector.
A method for manufacturing a turbocharger assembly comprising the steps of:
- providing a turbocharger defining a recess;
- providing an exhaust pipe and a connector having a flange region and a fastener region;
- inserting the flange region into the recess;
- and
- affixing the connector and the exhaust pipe to the turbocharger housing via at least one mechanical fastener.
