Abstract: A variable turbine geometry assembly includes an adjustment ring extending along and rotatable about an axis, at least one vane lever coupled to the adjustment ring, and at least one vane coupled to the at least one vane lever. The variable turbine geometry assembly also includes a biasing member coupled to the adjustment ring at a first circumferential location on the adjustment ring and coupled to the adjustment ring at a second circumferential location on the adjustment ring. The biasing member extends from the first circumferential location to the second circumferential location. The biasing member is operably in contact with the at least one vane lever between the first circumferential location and the second circumferential location to bias the at least one vane lever toward the adjustment ring and to reduce vibration between the adjustment ring and the at least one vane lever.

Abstract: A variable turbine geometry turbine turbocharger (1) includes a vane pack (50) disposed in the exhaust gas path upstream of the turbine wheel (12). The vane pack (50) includes vanes (30) that are rotatably supported between a pair of vane rings (34) and configured to adjustably control the flow of exhaust gas to the turbine wheel (12). In addition, a retainer (60, 160) secures the vane pack (50) to the bearing housing (16) in such a way that the vane pack (50) is mechanically decoupled from the turbine housing (4).

Abstract: A vane lever (46) for a guide apparatus (28) of a turbocharger (10) may include a base (49). The base (49) may include a bore (48) disposed therethrough. An arm (50) may extend from the base (49) and may be receivable in an aperture (42) of an adjustment ring (40) of the guide apparatus (28). A protuberance (52) may extend from the base (49) and may be capable of limiting axial movement of the adjustment ring (40).

Abstract: A number of variations may include a product comprising: a vane lever comprising a first end, a second end, a top surface, and a bottom surface; an opening which extends through the second end and which is defined by an inner surface, and wherein a perimeter of the inner surface comprises a plurality of vertical flutes which extend a length of the inner surface and which are constructed and arranged to displace a material of a vane shaft.
