Abstract: An electric machine includes a stator assembly and a bus bar assembly. The stator assembly includes a core with windings positioned on the core. The windings include in-slot portions, end turns, and leads. The leads extend from the in-slot portions at one of the ends of the core with ends of the leads extending axially past the end turns. The leads include a first plurality of leads positioned on a first side of the stator opposite a second plurality of leads positioned on a second side of the stator. The bus bar is substantially circular in shape and positioned radially inward from the end turns. The bus bar assembly includes three bus bars, each bus bar connecting at least one of the first plurality of leads to at least one of the second plurality of leads.

Abstract: The present invention relates to an adjustment mechanism (100) for variably adjusting the cross-section of a compressor inlet (22) and further relates to a corresponding compressor (20) including such an adjustment mechanism (100). The adjustment mechanism (100) comprises a plurality of rotatable orifice elements (110) and an actuation ring (120). The actuation ring (120) is mechanically coupled to the plurality of orifice elements 110 such that rotation of the actuation ring 120 causes movement of the orifice elements 110. The movement of the orifice elements (110) thereby adjusts the cross-section of a compressor inlet (22). The adjustment mechanism (100) further comprises a plurality of support members (140) which are arranged axially between the plurality of orifice elements (110) and the actuation ring (120). Additionally, the adjustment mechanism (100) comprises a spring (130), more specific a ring-shaped wave spring. The spring (130) is adapted to axially preload the plurality of orifice elements (110) and the actuation ring (120) when being in a mounted state.

Abstract: The invention relates to a bearing unit for a turbocharger rotor. The bearing unit comprises a bearing housing and a bearing bush which is arranged in a central bore for radially mounting a turbocharger rotor in the bearing housing. In the region of a first axial end, the bearing bush has a radially outwardly extending projection. The projection is designed to interact with the bearing housing as an anti-rotation safeguard for the bearing bush.

Abstract: A method includes determining a value of an operational motor current limit and setting a value of a startup current limit equal to a predetermined value in excess of the value of the operational motor current limit if a set of predetermined conditions is satisfied. The method includes determining that operation of the engine has been interrupted, operating the electric motor of the variable valve timing mechanism with a current having a magnitude that is less than or equal to the startup current limit after determining that operation of the engine has been interrupted, determining that operation of the engine has resumed, and operating the electric motor of the variable valve timing mechanism with a current having a magnitude that is less than or equal to the operational motor current limit after determining that operation of the engine has resumed.

Abstract: A stack of disk springs are placed between a second piston of a dual hydraulic variable force tensioner system and a hydraulic tensioner arm to allow much higher spring rates if desired. The springs may be stacked in multiple configurations to provide different spring rates. Package space can be reduced depending on the number of springs and orientations of said springs within the tensioner arm.

Abstract: A transfer case for use in a vehicle, with the vehicle including a powertrain, includes an input shaft configured to be rotatably coupled to the powertrain. The transfer case also includes a primary output shaft rotatably coupled to the input shaft, and a secondary output shaft selectively rotatably coupled to the primary output shaft. The transfer case further includes a planetary gearset disposed between and rotatably coupled to the input shaft and the primary output shaft. The transfer case also includes an input member and an electric machine. The input member is rotatably coupled to the electric machine and the input shaft to provide rotational torque from the electric machine, to the input shaft, and to the primary output shaft.
