Abstract: The present invention relates to an actuation device for a compressor inlet adjustment mechanism. The actuation device comprises a housing part and a lever assembly. The lever assembly comprises a bearing section, an input section and an output section. The output section is configured to be coupled to an adjustment ring of the adjustment mechanism on a first side of the housing part. The input section can be coupled to an actuator rod on a second side of the housing part. The lever assembly is rotatably mounted in the housing part via the bearing section on the compressor inlet side here.

Abstract: A system and method is provided for controlling an electric machine rotatably coupled to a rotatable shaft of an electronically-controlled one of a turbocharger and an exhaust-driven turbo supercharger fluidly coupled to an exhaust duct of an internal combustion engine. An operating temperature of a component of the engine is determined or estimated an operating temperature of a component of the engine or coupled to the engine, which is compared to a threshold temperature. The electric machine is controlled to operate as a motor in response to the determined or estimated temperature of the component being below a threshold temperature.

Abstract: A friction material includes a friction-generating layer, a core layer, and a base layer. The friction-generating layer presents a friction-generating surface and includes a friction-generating material. The friction-generating material includes friction-adjusting particles. The core layer is adjacent to the friction-generating layer and includes a core material. The core material includes core fibers. The base layer is adjacent to the core layer such that the core layer is disposed between the friction-generating and base layers. The base layer presents a bonding surface facing opposite the friction-generating surface of the friction-generating layer. The base layer includes a fibrous material. The fibrous material includes base fibers chosen from aramid fibers, carbon fibers, cellulose fibers, acrylic fibers, polyvinyl alcohol fibers, glass fibers, mineral fibers, and combinations thereof. A resin is present in at least one of the friction-generating layer, the core layer, and the base layer.

Abstract: A dual volute turbocharger for use with an internal combustion engine includes a valve for controlling exhaust gas flow to a turbine housing interior of the dual volute turbocharger. The dual volute turbocharger also includes a first volute and a second volute each adapted for fluid communication with the internal combustion engine. The dual volute turbocharger further includes a wall separating the first and second volutes and a valve seat. The valve seat and the wall collectively define a valve cavity. The valve is movable between a closed position and an open position. The valve and the wall of the turbine housing collectively define a first cross-sectional flow area. The valve and the valve seat collectively define a second cross-sectional flow area. A method of controlling the valve of the dual volute turbocharger is also disclosed.

Abstract: A shifting system for a vehicle transmission includes an input member and a selectable one-way clutch rotatably coupled to the input member. The selectable one-way clutch is moveable between first, second, and third clutch positions. The shifting system also includes a disconnect coupled to the input member and moveable between first and second disconnect positions, and an output member selectively rotatable with the input member. The shifting system further includes a shifting assembly for selectively rotatably coupling the input and output members. The shifting assembly includes an input hub coupled to the input member, having a disconnectable component engageable with the disconnect, and having a clutch engagement component. Clutch plates are coupled to the clutch engagement component and are moveable between engaged and disengaged positions. A clutch plate carrier is coupled to the clutch plates and output member to transmit torque from the clutch engagement component to the output member.

Abstract: A lock pin for a VCT device that has a locked position, locking a housing assembly relative to a rotor assembly of the variable cam timing device, and an unlocked position. The lock pin has a body comprising a first diameter with a first area, a second diameter with a second area, and a chamber formed between the first area of the first diameter and the second area of the second diameter for receiving fluid, the first area being greater than the second area. When fluid is applied to the chamber through the variable cam timing phaser, a difference between first area and the second area defining the chamber creates a force imbalance, such that the oil pressure applied to the chamber of the body assists in maintaining the Sock pin in the locked position.

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: A friction material has a first outermost surface and a second outermost surface spaced apart from the first outermost surface. The friction material includes a base which forms at least a portion of the first outermost surface. The base includes fibers present in an amount of from 20 to 80 weight percent, a filler present in an amount of from 20 to 80 weight percent, and a deposit which forms at least a portion of the second outermost surface and includes a friction adjusting agent. The friction material further includes a resin disposed throughout the friction material. The deposit is disposed in the friction material in a gradated pattern. At least a portion of the deposit is exposed to the environment and the second outermost surface has a surface roughness of from 2 to 11 micrometers as determined by non-contact laser measurement according to ISO 25178.
