An electric machine including a stator core having an outer circumferential surface and an axial row of raised projections that extend radially outboard from the outer surface. The raised projections are axially spaced from each other to define circumferential channels therebetween. A housing defines a cavity that receives the stator core. The housing has an inner circumferential surface in contact with the raised projections and radially spaced from the outer surface of the core to define a void space in fluid communication with the channels. The void space and the channels cooperate to form a fluid circuit that overlays the outer circumferential surface such that the fluid is in direct contact with the stator core.

Electric machine thermal management

A stator includes a plurality of same laminations each defining a piloting tab on a perimeter thereof, and stacked to form a stator body and such that the piloting tabs define at least two axially extending serrated edge portions spaced apart from one another around a perimeter of the stator body or at least two sets of axially aligned housing contact pads spaced apart from one another around the perimeter.

Stator with piloting supports

A vehicle includes a housing, an electric machine configured to propel the vehicle, and a clamp. The housing defines an internal cavity, and has first and second stepped surfaces extending radially inward and into the cavity. The electric machine is disposed within the cavity. The electric machine has a stator that includes third and fourth stepped surfaces that extend radially outward. The clamp engages the first and third stepped surfaces, and axially forces the fourth stepped surface into engagement with the second stepped surface.

Fastening system for an electric machine

A powertrain includes a transmission case, a transfer case, a front axle housing, and a webbed brace. The transfer case and front axle housing are directly fastened to the transmission case. The webbed brace is directly fastened to the transmission case, the transfer case, and the front axle housing to form a powerplant system. The webbed brace is configured such that a bending frequency of the powerplant system falls within a predefined range.

Brace for powerplant

A transmission for a motor vehicle includes an input shaft, a transmission pump, a transmission sump and a pump-driving element, which is preferably a drive gear. The drive gear and the transmission pump are located in the transmission sump. Power is transmitted from the input shaft to the transmission pump through the drive gear. In a preferred embodiment, power is transmitted from the input shaft to the drive gear through at least one gear, and from the drive gear to the transmission pump through a pump shaft. The drive gear is preferably at least partially enclosed by a shroud, coupled to the transmission pump, in order to separate the drive gear from transmission fluid located in the transmission sump and thereby reduce drag on the drive gear. The shroud preferably also includes a discharge port so that transmission fluid located in the shroud is expelled through the discharge port when the drive gear rotates.

Transmission for motor vehicle and method of pumping transmission fluid through the transmission

A differential mechanism with offset, self-aligning spherical side gears and wider side gear separation to provide differential mechanism that is less expensive and easier to assemble. The differential mechanism includes a centerpoint of one surface or gear that is offset from a centerpoint of the chamber or casing along an axle centerline in a direction away from an opposing surface or gear.

Method and design of an automotive differential

A differential gear assembly including a differential housing and a ring gear mounted externally to the differential housing by a clamp. The differential housing and the ring gear each include an annular flange extending therefrom and the clamp includes a pocket which is adapted to receive the annular flanges therein. In another aspect, the flanges include opposing angled surfaces and the pocket includes opposing angled sides, whereby when the clamp is placed to the flanges, the angled surfaces of the flanges engage the angled sides of the clamp such that the clamp provides an axial clamping force to the flanges.

Differential assembly

A differential gear assembly including a differential housing, a pair of side gears substantially axially aligned and spaced apart from each other supported by the differential housing and engaging an axle half-shaft, and a plurality of pinion gears substantially axially aligned and spaced apart from each other. The pinion gears engage the side gears and include an outwardly facing first side and an inwardly facing second side. A ring gear is mounted externally to the differential housing and includes features which engage the first sides of the pinion gears to support the pinion gears within the differential gear assembly while allowing rotational movement of the pinion gears.

Differential gear assembly

A direct drive differential containing a ring gear and a differential pin attached directly to the ring gear. This arrangement changes the load path through the differential case that allows for a new design to be created. The ring gear has a slot and the differential pin has a flat on the sides that mate together when assembled. The differential pin is round and the ring gear has a radius that mate together when assembled. The ring gear has a diameter machined into the inside ring diameter but allows a pin with slots to be assembled. The pin locks into place in the ring gear by rotating the pin during assembly. The ring gear has a through hole or is drilled and tapped and the differential pin has a hole therefore the two parts can be locked together in place.

Vehicular differential with ring gear directly loading the differential pin

A differential gear assembly for an automobile includes an annular ring gear, a differential case, a pair of side gears substantially axially aligned and spaced apart from each other and adapted to be supported by the differential case and to engage an axle shaft of the automobile, and a pair of differential pinion gears substantially axially aligned and spaced apart from each other, and adapted to engage the side gears. A differential pin is secured to and extends diametrically across the ring gear and is adapted to support the differential pinion gears in engagement with the side gears and to allow rotational movement of the differential pinion gears about the differential pin.

Differential gear retention system

A differential gear assembly including a differential housing. A pair of side gears substantially axially aligned and spaced apart from each other, wherein the side gears are adapted to be supported by the differential housing and to engage axle shafts. A pair of pinion gears substantially axially aligned and spaced apart from each other, wherein the pinion gears are adapted to engage the side gears. A ring gear is mounted externally to the differential housing and a pinion pin engages and extends diametrically across the ring gear. The ring gear includes features adapted to receive the ends of the pinion pin and to position the pinion pin relative to the ring gear such that a center of mass of the ring gear is aligned with a center of mass of the pinion pin.
