Abstract
A turbocharger device includes a case having a turbine portion and a bearing portion connected to and extending from the turbine portion. The turbine portion defines a cavity that houses a turbine wheel and receives exhaust gas that rotates the turbine wheel. The bearing portion houses a shaft connected to the turbine wheel. The bearing portion has a radial thickness between an exterior surface and an interior surface. The interior surface defines a central channel. The bearing portion holds a bearing system that supports the shaft within the central channel. The bearing portion includes a lattice structure within the radial thickness. The lattice structure is a repeating three-dimensional array of frame segments connected to one another at junctions. The lattice structure engages a turbine back wall that is located between the turbine portion and the bearing portion. The lattice structure defines interstitial spaces between the frame segments.
