摘要： An assembly can include a turbine housing that includes a bore, a wastegate seat, wastegate passages that extend to the wastegate seat and a divider wall disposed between the wastegate passages where the divider wall includes a divider wall surface; a rotatable wastegate shaft configured for receipt by the bore; a wastegate arm extending from the wastegate shaft; and a wastegate plug extending from the wastegate arm where the wastegate plug includes a contact portion that contacts the wastegate seat to cover the wastegate passages in a closed state and a mesh that contacts the divider wall surface in the closed state.

摘要： A turbine housing assembly can include a turbine housing that defines a rotational axis for a turbine wheel; and a cartridge receivable by the turbine housing, where the cartridge includes spacer posts and a plate component that includes spacer post openings, where the spacer posts are laser beam welded into the spacer post openings to form laser beam welds to define an axial vane clearance between the plate component and a surface of the turbine housing contacted by ends of the spacer posts, and where each of the laser beam welds includes a power ramp-up area, an intermediate area and a power ramp-down area, where the power ramp-down area curves away from the power ramp-up area to reduce weld defects.

摘要： A method of assembling a turbocharger having a vaned turbine nozzle includes first forming a sub-assembly of a center housing, shaft, bearings, compressor wheel, turbine wheel, and vane assembly. The vane assembly is held captive in attachment to the center housing by an annular heat shield that includes prongs or the like at its inner and outer peripheries for respectively engaging a first catch formed on the center housing and a second catch formed on the nozzle ring of the vane assembly. The heat shield forms a snap fit to the center housing and nozzle ring, thereby connecting the cartridge to the center housing. The whole sub-assembly is then joined to the turbine housing, in the process axially compressing the heat shield and a spring shroud for exerting an axial biasing force on the nozzle ring.

摘要： A turbocharger turbine wastegate assembly includes a turbine housing that includes a wastegate seat and a bore; a bushing with a stepped bore that includes an axial face; a wastegate that includes a shaft, a plug and an arm, where the shaft includes an end portion, a first axial face, a journal portion, a second axial face and a shoulder portion, where the first axial face is defined at least in part by an end portion diameter and a journal portion diameter, and where the second axial face is defined at least in part by the journal portion diameter and a shoulder portion diameter; a mesh spacer disposed radially about an axial length of the end portion of the shaft between the axial face of the stepped bore of the bushing and the first axial face of the shaft; and a control arm connected to the end portion of the shaft where an axial length of the bushing is disposed between the mesh spacer and the control arm.

摘要： A turbine housing assembly can include a turbine housing that includes an exterior surface, an interior surface that includes a wastegate seat, and a bore that extends between the interior surface and the exterior surface; a bushing disposed at least partially in the bore where the bushing includes a bushing bore; a wastegate that includes a shaft that extends through the bushing bore to a shaft end, a shaft shoulder disposed in the bushing bore, a plug, and an arm disposed between the shaft and the plug; a ring disposed at least in part in the bushing bore between the shaft shoulder and the shaft end; and a control arm connected to the shaft proximate to the shaft end to define an axial distance between a surface of the control arm and the shaft shoulder where the ring has an axial length that is less than the axial distance.
