摘要： Induced currents in a multi-phase AC motor may be attenuated by operating the multi-phase AC motor with an AC choke surrounding an AC bus providing multi-phase AC voltage to multi-phase AC stator windings in a stator, wherein the AC choke may include an effective bandwidth at least covering resonant frequencies of a capacitance between the multi-phase AC stator windings and the stator or a frame of the AC motor.

摘要： The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

摘要： Assembly tools or aides assist the installation of chains and sprockets for a power take off in a motor vehicle automatic transmission. A first tool is an assembly clip having a semi-circular channel that engages the periphery of a chain disposed about a socket. The clip facilitates installation of the chain and a first sprocket through a slot or other opening in the side of a transmission housing while a second sprocket is being secured to a transmission shaft and the chain is engaged thereabout. The clip also facilitates positioning of the first sprocket in a desired location, typically on a driven shaft while retaining the chain thereabout. A second tool includes a pair of elongate, parallel pins which cooperate with the clip and the first sprocket to hold it in place during assembly of certain components of the transmission such as a power take off shaft or bulkhead.

摘要： A retention clip is employed in a cooling subsystem of an electric energy generation and storage system having a battery cell. The cooling subsystem includes a coolant header extending proximate the battery cell and having an inlet fitting and an outlet fitting. The cooling subsystem also includes an inlet manifold configured to connect with the inlet fitting and an outlet manifold configured to connect with the outlet fitting. The inlet and outlet manifolds are together configured to circulate coolant through the coolant header. The retention clip is configured to engage and hold each of the inlet manifold and the outlet manifold and snap onto the coolant header to thereby fix the inlet manifold relative to the outlet manifold and fix and seal the inlet manifold and the outlet manifold to the coolant header.

摘要： A power take-off (PTO) system for a motor vehicle includes a PTO housing. The PTO housing is mounted to a transmission case. A disconnect clutch assembly is positioned within the PTO housing acting when supplied with a first volume of a pressurized oil from the transmission case to engage an output shaft member. A controlled lube oil circuit is isolated from the first volume of the pressurized oil. The controlled lube oil circuit supplies a second volume of the pressurized oil directly to the disconnect clutch assembly to lubricate the disconnect clutch assembly. A lube oil drain return is connected to the PTO housing. The lube oil drain return receives oil that collects inside the PTO housing to be returned to the transmission case.
