An integrated pinion shaft and constant velocity joint (PS/CVJ) assembly for use in motor vehicle driveline applications to transfer torque between a propshaft and a ring gear. The PS/CVJ assembly includes a pinion shaft having a pinion gear segment meshed with the ring gear and a hollow pinion shaft segment. The PS/CVJ assembly also includes a constant velocity joint having an inner race coupled to the propshaft and an outer race integral with or fixed to an end portion of the pinion shaft segment.

The present disclosure provides a differential gear to be mounted on a vehicle, including a pair of side gears, at least two pinion gears meshed with the side gears, and a differential case that houses the side gears and the at least two pinion gears. Lubricating oil is supplied to and discharged from the inside of the differential case via an opening portion. The differential case includes at least two seat surfaces formed on the inner peripheral surface of the differential case so as to support the pinion gears, weir portions provided between the adjacent seat surfaces and extending in a direction along the rotational direction of the differential case to connect between the adjacent seat surfaces, and an oil reservoir portion formed on the inner peripheral surface by the weir portions so as to be positioned on the opposite side, in the axial direction of the side gears, of the opening portion from the weir portions. Consequently, it is possible to render the differential gear compact by suppressing a shortage of lubricating oil for a sliding portion well.

The power transmission device includes a speed reducer and a differential. The speed reducer includes a sun gear fixed to a hollow input shaft, stepped pinions, first and second ring gears. The stepped pinion has input and output gears, with the input gear engaging the sun gear. A first ring gear is fixed to a housing and engages the input gear. The second ring gear engages the output gear. The differential has a differential housing and first and second output shafts. The differential housing is fixed to the second ring gear. The first and second output shafts are arranged concentrically with the input shaft and extend in opposite directions from the differential housing. One of the first output shaft and the second output shaft passes through the inside of the input shaft. The differential housing is positioned to be surrounded by the output gears of the stepped pinions.

A drive axle assembly includes a drive axle housing and a differential disposed within the drive axle housing, the differential including a pinion gear configured to be driven by an input shaft, a crown gear driven by the pinion gear to rotate about a rotation axis, and a plurality of differential gears driven by the crown gear and configured to be drivingly coupled to a first and a second driven shaft. The drive axle assembly further includes a first lubricant baffle fixed to the drive axle housing and having a first axial end portion facing a toothed front face of the crown gear. And the drive axle assembly includes an exchangeable axial spacer to set an axial position of the first axial end portion of the first lubricant baffle.

A drive axle system including a first axle assembly having an input shaft in driving engagement with an under-drive arrangement, an inter-axle differential in driving engagement with the under-drive arrangement, a through drive shaft in driving engagement with the inter-axle differential, a first axle drive pinion in driving engagement with the inter-axle differential, and a first axle differential arrangement including a first axle ring gear in driving engagement with the inter-axle differential through the first axle drive pinion. The drive axle system further includes the second axle assembly in driving engagement with the through drive shaft. The second axle assembly includes a second axle drive pinion drivingly engaged with the through drive shaft and meshingly engaged with a second axle ring gear of a second axle differential arrangement. The under-drive arrangement is configured to reduce a drive ratio of the first axle assembly and the second axle assembly.

A power system includes an electric motor, a transmission, and a differential gear system. The transmission includes a first gear that is mechanically connected to the electric motor, a second gear that has a rotation axis in common with the first gear and is mechanically connected to a differential gear casing of the differential gear system, a pinion gear that meshes with the first gear and the second gear, and a pinion holder that rotatably supports the pinion gear. The pinion holder has a pinion gear supporting portion which is disposed on a side of the differential gear casing of the differential gear system to support the pinion gear, relative to a meshing portion between the second gear and the pinion gear. An inner diameter of the second gear at the meshing portion is equal to or smaller than an outer diameter of the pinion holder.

A ram air turbine is provided that utilizes a one-piece strut. The strut includes an integral gearbox section and an integral drive section. Within the strut, a turbine shaft and a bevel gear engages a driveshaft and a pinion gear, which transfers rotation from the turbine to a generator. The strut may be machined from a single piece of metal, such as aluminum.

A roller component configured to engage with a toothed component such that when the roller component is engaged with the toothed component, rotational movement of one of the roller component and the toothed component drives linear movement along an actuation direction of the other one of the roller component and the toothed component. The roller component includes a support member and cantilevered first rollers, each of which has a mounted end connected to a first side of the support member such that each first roller is rotatable relative to the support member about a roller axis perpendicular to the actuation direction, and an unsupported end distal from the mounted end.

An axle assembly with a housing, a shaft received in the housing, a shaft bearing supporting the shaft for rotation relative to the housing about a shaft axis, a differential assembly, an annular band and a secondary retainer. The shaft bearing has an inner race, which is received on and directly engaged to the shaft, and an outer race that is received on and directly engaged to the axle housing. The differential assembly has an output member that is non-rotatably coupled to the shaft. The annular band is fixedly coupled to the shaft at a location along the axle shaft axis between the inner race and the output member. The secondary retainer is disposed along the axle shaft axis between the annular band and the output member and is configured to limit movement of the annular band along the axle shaft axis in a direction toward the output member.

A drive axle system including a first axle assembly having an input shaft in driving engagement with an under-drive arrangement, an inter-axle differential in driving engagement with the under-drive arrangement, a through drive shaft in driving engagement with the inter-axle differential, a first axle drive pinion in driving engagement with the inter-axle differential, and a first axle differential arrangement including a first axle ring gear in driving engagement with the inter-axle differential through the first axle drive pinion. The drive axle system further includes the second axle assembly in driving engagement with the through drive shaft. The second axle assembly includes a second axle drive pinion drivingly engaged with the through drive shaft and meshingly engaged with a second axle ring gear of a second axle differential arrangement. The under-drive arrangement is configured to reduce a drive ratio of the first axle assembly and the second axle assembly.
