A continuously variable mechanical belt drive mechanism drives the accessory as one mode of operation. An electric motor along with a planetary roller screw mechanism which converts rotary motion to axial motion is used to change the sheave position and thus the drive ratio. Upon disengagement of the mechanical drive mode, the electric motor can be used to drive the accessory in a second mode.

Abstract: A turbocharger (100) has an asymmetric, twin scroll volute design, having a first volute (101) and a larger second volute (102). The larger second volute (102) eliminates the need for a wastegate and its associated actuator. The smaller first volute (101) is sized for rapid transients and rated torque, while the second volute (102) is sized such that the turbine inlet pressure is satisfactory for rated power. Furthermore, the turbocharger (100) preferably incorporates a mixed flow turbine wheel (108) rather than a radial wheel, which allows for a larger wheel size to be used while still maintaining inertia. The turbine housing (103) is improved wherein the first and second volutes (101) and (102) are asymmetric with respect to each other and preferably, are leaned toward the bearing housing to match the axial component of the mixed flow turbine wheel inducer (112).

Abstract: A turbocharger (10) includes a housing (12, 14, 16) and an actuating mechanism (46) for actuating a device (40) within the housing (12, 14, 16). A pivot shaft (42) has an inside end (48) inside the housing (12, 14, 16) and an outside end (82) outside the housing (12, 14, 16). The pivot shaft (42) is rotatably mounted in a bore (64) in the housing (12, 14, 16) for transmitting an actuating movement from outside the housing (12, 14, 16) to the actuating mechanism (46). A bushing (62) is disposed in the bore (64). The bushing (62) includes an asymmetric portion (68) that extends inside the housing (12, 14, 16) to support the inside end (48) of the pivot shaft (42).
