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 wheel includes a hub portion configured to rotate about a rotational axis. A plurality of blades extends radially outward from the hub portion. Each blade of the plurality of blades includes a leading edge and a trailing edge. The hub portion and the plurality of blades include a substrate metal that includes aluminum or an alloy thereof. The substrate metal of the plurality of blades has coated directly thereon a first coating layer including electroless nickel-phosphorous. The first coating layer has coated directly thereon a second hard coating layer that overlies the leading edges of the plurality of blades and that is formed of a physical vapor deposition-compatible material.

摘要： Methods and systems for estimating driving range for an electric vehicle. Each of Kalman Filter-based and receding horizon-based approaches to estimating driving range and providing driving range data to a driver of a vehicle are illustrated. Approaches configured for use when a destination is not known as well as when a destination is known are illustrated.

摘要： A fluid compressor device includes a compressor section and a motor section. The compressor device further includes a working fluid first flow path that extends in a downstream direction through the motor housing to the compressor inlet. The working fluid first flow path is configured to receive a first flow of a working fluid that flows downstream through the motor housing past the electric motor and into the compressor inlet to be compressed by the compressor section. Additionally, the compressor device includes a working fluid second flow path extending through the housing. The working fluid second flow path is configured to receive a portion of the working fluid from the compressor section and direct the portion to the bearing system before merging with the working fluid first flow path.

摘要： Models that employ both measurable engine parameters as well as predictable engine parameters may be used to determine when a thermostat is malfunctioning before the thermostat malfunction results in an engine breakdown. Particular models may be used to provide an estimated coolant temperature and an estimated thermostat position. The estimated coolant temperature can be compared to an actual measured engine coolant temperature. The estimated thermostat position can be evaluated with respect to what the thermostat position should be given a particular engine coolant temperature. In some cases, comparison between a healthy model and a faulty model may be used to ascertain thermostat health.

摘要： A rotor assembly for a turbomachine having a permanent magnet electric motor that defines an axis of rotation includes a jacket member. The rotor assembly also includes a magnet member that is received within the jacket member. The magnet member has a first longitudinal end and a second longitudinal end that are separated along the axis of rotation. The rotor assembly also includes a first shaft structure that is attached to the first longitudinal end and a second shaft structure that is attached to the second longitudinal end. The magnet member is solitary and unitary and has a solid core.

摘要： A turbomachine includes a housing with an e-machine housing. Also, the turbomachine includes a rotating group supported for rotation within the housing. Moreover, the turbomachine includes an e-machine that is configured as at least one of an electric motor and an electric generator, that is operatively coupled to the rotating group, and that includes a stator that is housed within the e-machine housing. Furthermore, the turbomachine includes a thermal bridge member that extends between the stator and the e-machine housing to define a thermal path for heat to transfer from the stator to the e-machine housing. The e-machine housing includes a thermal bridge retainer member that defines an outer boundary of the thermal bridge member.

摘要： A turbocharger includes a housing and a rotating group supported for rotation within the housing. The rotating group includes a compressor wheel disposed within a compressor section of the turbocharger, and the rotating group includes a turbine wheel disposed within a turbine section of the turbocharger. The turbine wheel includes a bleed pressure surface. The turbocharger further includes a bleed passage that extends at least partly through the housing to fluidly connect the compressor section to the turbine section. The bleed passage is configured to direct a bleed flow of fluid from the compressor section to the bleed pressure surface to supply a thrust counterbalance load to the bleed pressure surface.
