The present invention relates to a lubricating system for a vehicle transmission component. The system comprises a lubricating circuit (44) for supplying lubricant to a transmission component, the circuit (44) including a reservoir (46), a supply path for supplying lubricant from the reservoir (46) to the transmission component, and a return path for returning lubricant from the transmission component to the reservoir (46). The system also comprises an electrical pump (52) for pumping lubricant from the reservoir (46) to the transmission component and a controller (56) arranged to monitor a driving condition and configure the electrical pump (52) to pump a predetermined flow rate of lubricant to the transmission component based on the current driving condition.

A lubrication system for a gearbox assembly for a turbine engine. The gearbox assembly includes a gear assembly including one or more gears and one or more bearings. The lubrication system includes a sump. The sump is a primary reservoir that has a first lubricant level. The lubrication system also includes a secondary reservoir in the gearbox assembly. The secondary reservoir has a second lubricant level that is greater than the first lubricant level. A plurality of drain ports includes a first drain port and a second drain port. The lubrication system fills the secondary reservoir with lubricant between the first lubricant level and the second lubricant level and a portion of the lubricant drains though the second drain port. The one or more gears collects the lubricant to supply the lubricant from the secondary reservoir to the one or more gears or to the one or more bearings.

A drive module assembly includes a housing defining a housing interior for containing a lubricant. The housing interior has a first interior side adjacent a first housing wall of the housing and a second interior side spaced from the first interior side and adjacent a second housing wall of the housing. The drive module assembly also includes an input shaft extending along an input axis and coupled to the housing and configured to receive rotational torque from a power source, a gear train rotatably coupled to the input shaft, and an output shaft rotatably coupled to the gear train. The drive module assembly further includes an oil housing disposed in the housing interior between the first housing wall and the second housing wall. The oil housing defines an oil housing interior that is configured to retain a portion of the lubricant.

An electric beam axle for use in an electric or hybrid motor vehicle includes a valve positioned between a differential case and an axle tube. The valve includes a valve housing with a fluid flow path extending through the valve housing, and a valve member positioned within the fluid flow path of the valve housing. The valve can also include a stop coupled to the valve housing, the stop being configured to retain the valve member within the fluid flow path of the valve housing. The valve member is configured to prevent fluid from flowing through the fluid flow path and into the axle tube of the electric beam axle when the electric or hybrid motor vehicle is driving across steep road grades and/or under lateral acceleration (cornering) events.

A fluid delivery system includes a reservoir for storing fluid, a rotary pump having a first pump port and a second pump port, a first fluid conduit connecting the first pump port to the reservoir, and a second fluid conduit connecting the second pump port to the reservoir. The rotary pump rotates in a first delivery direction in a normal mode and in a second delivery direction in an alternative mode. A first valve separates the first pump port from the reservoir when the rotary pump is in its alternative mode, and a second valve separates the second pump port from the reservoir when the rotary pump is in its normal mode.

A method of controlling a transmission having a gearbox and a pump operable to circulate a fluid through the gearbox, includes sensing an acceleration of the vehicle, and adjusting an operating state of the pump. The operating state of the pump is adjusted to change the operating state of the pump from an initial operating state, to an adjusted operating state, when the acceleration of the vehicle is greater than an acceleration threshold. When the acceleration of the vehicle decreases from being greater than the acceleration threshold to being below the acceleration threshold, the operating state of the pump is returned to the initial operating state. The operating state of the pump may include a speed of the pump, a control signal representing a fluid flow rate for the current speed of the pump, or a fluid flow circuit for supplying the fluid to the pump.

Vehicles, oil intake systems for vehicles, and methods for manufacturing oil intake systems for vehicles are provided. A method for manufacturing an oil intake system for a vehicle includes providing an oil reservoir having an internal volume with an internal shape including an oil reservoir bottom; determining a selected amount of oil received in the oil reservoir; selecting a maximum positive pitch angle of a first plane of an upper surface of the selected amount of oil in the oil reservoir; selecting a minimum negative pitch angle of a second plane of the upper surface of the selected amount of oil in the oil reservoir; determining a bottom plane at a selected positive distance above the oil reservoir bottom; determining a shape and a size of an oil pick-up tube and of an opening in the oil pick-up tube to locate the opening below the first plane at the maximum positive pitch angle and below the second plane at the minimum negative pitch angle, wherein the opening is defined by a peripheral edge of the oil pick-up tube, wherein the peripheral edge lies substantially within an opening plane, wherein the opening plane has a positive pitch angle of at least half of the maximum positive pitch angle; and fabricating the oil pick-up tube with the shape, the size, and the opening.

A method for installing an anchor having: making a hole into the material in which the anchor is to be installed, by using a hammer drill; after associating an anchor driver with the chuck of the hammer drill, using the so created anchor driver-hammer drill first assembly, with the hammer drill in hammer mode, to hammer the anchor into the hole; and, after switching the hammer drill to drill mode, tightening the nut or bolt of the anchor using the anchor driver-hammer drill first assembly, or a second assembly comprising the hammer drill and a socket.

A vehicle drive device that includes a case forming a first accommodating space that accommodates a speed change device and a second accommodating space that accommodates a rotary electric machine; an storage that is disposed under the first accommodating space and stores oil; a hydraulic pump including a suction that suctions the oil from the oil storage; a first oil passage that supplies the oil discharged by the hydraulic pump to the speed change device as hydraulic oil; a second oil passage that supplies the oil discharged by the hydraulic pump to the rotary electric machine as cooling oil; and a third oil passage that returns the oil supplied to the rotary electric machine, from the second accommodating space to the oil storage, by allowing the oil to flow in a direction from the second accommodating space toward the first accommodating space.
