An axle assembly having a differential carrier that includes a bearing support wall that at least partially defines a first lubricant chamber. A rotor output flange that is fixedly coupled to a rotor may at least partially defines a second lubricant chamber. At least one seal may separate the first lubricant chamber from the second lubricant chamber.

An axle system and a method of control. The axle system may include an axle controller that may be directly electrically connected to a first speed sensor and a second speed sensor. The axle controller may control movement of a shift collar that may be selectively engageable with first and second gear ratios.

The invention relates to a bearing arrangement for a bevel gear drive, comprising a housing (14), a pinion (12), which includes a pinion shaft (12a) and a bearing journal (12b), and a crown wheel (13), which is meshed with the pinion (12), wherein the pinion (12) is supported with respect to the housing (14) via the bearing journal (12b) and the pinion shaft (12a) with the aid of antifriction bearings (15, 16).

It is provided that the pinion (12) is supported via two tapered roller bearings (15, 16) pitched with respect to one another, wherein the first tapered roller bearing (15) is arranged on the bearing journal (12b) and the second tapered roller bearing (16) is arranged on the pinion shaft (12a) and their pressure lines (d) form an X arrangement.

A bearing type gear system for use with low seam crawler drive for underground mining equipment. The Bearing type gear system is comprised generally of a shaft, a set of multiple lubrication reservoirs, a needle bearing set or sets, a gear or gears, and gear teeth on the gear(s). As lubrication is sent into the shaft and gear area, the reservoirs along the shaft will pick up and hold portions of the lubrication. The reservoirs of the design herein, holding lubrication, can then help distribute the lubrication into the bearings over a greater amount of time. The reservoirs are of a number and location of intervals to provide sufficient lubrication to the entire surface of the shaft of the reservoirs as the shaft turns.

A modular electric axle head assembly for a vehicle. An axle assembly of the vehicle includes a banjo portion with a first opening extending from an inner surface to an outer surface of an inboard side of the banjo portion. At least a portion of a differential assembly disposed within at the banjo portion of the axle assembly and is drivingly connected to at least a portion of a gear assembly. The gear assembly is also drivingly connected to a motor output shaft. At least a portion of the gear assembly is disposed within a hollow portion of a gear assembly housing. An outboard portion of the gear assembly housing has a mounting flange that is integrally connected to the inboard side of the banjo portion. A first and second protruding portion extends from the axle assembly mounting flange and provides rotational support for the differential assembly.

A tapered roller bearing includes a cage supporting a plurality of tapered rollers. The cage includes a large-diameter annular portion; a small-diameter annular portion; pillars through which the large-diameter annular portion and the small-diameter annular portion are coupled together; and pockets in which the respective tapered rollers are disposed. A space is defined between the outer ring and the inner ring, and constitutes an oil flow path through which lubricating oil (a) flows from the side of the small flange to the side of the large flange. Each pillar includes, in its radially inner surface, an oil groove in which lubricating oil is retained. When the cage rotates, the lubricating oil retained in the oil grooves of the pillars is scattered out of the oil grooves, thereby preventing seizure between the large-diameter end surfaces of the tapered rollers and the large flange of the inner ring.

A final drive for a motor vehicle, with a first input shaft, a second input shaft, a first output shaft and a second output shaft, the first input shaft being permanently coupled to the first output shaft by a first crown gear drive and the second input shaft being permanently coupled to the second output shaft by a second crown gear drive. The first input shaft and the second input shaft are arranged coaxially with each other and the first output shaft and the second output shaft extend in opposite directions starting from the respective crown gear drives, an axial plane extending the rotational axes of the input shafts and encloses a plane perpendicular to the axis plane with the rotational axes of the output shafts.

A final drive for a motor vehicle, comprising a first input shaft, a second input shaft, a first output shaft, and a second output shaft, wherein the first input shaft is permanently coupled to the first output shaft by a first ring gear transmission and the second input shaft is permanently coupled to the second output shaft by a second ring gear transmission. The first input shaft and the second input shaft are arranged coaxial to each other and the first output shaft and the second output shaft extend from the respective ring gear transmissions in opposite directions, wherein an axis plane contains the axes of rotation of the input shafts and a plane perpendicular to the axis plane includes an angle of at least 75 and at most 90.

An electric drive unit with a housing, a motor coupled to the housing and having a motor shaft, a differential assembly, a pair of output shafts, and a transmission that transmits rotary power between the motor shaft and the differential input member. The differential assembly and the transmission are received in the housing. The differential assembly has a differential input member and a differential a pair of differential output members that are rotatably coupled to the output shafts. The transmission has a transmission output member that is coupled to the differential input member for rotation therewith. An optional mechanical input assembly can be housed in the housing and can have a ring gear, which can be coupled to the differential input member for rotation therewith, and an input pinon that can be meshingly engaged to the ring gear.

Methods and systems for a clutch cartridge are provided. The clutch cartridge includes, a dog clutch including a clutch ring slidingly engaged with a tube shaft and including a first toothed interface and a second toothed interface, where the dog clutch is designed to selectively engage a first gear and a second gear. The clutch cartridge further includes a first bearing coupled to the tube shaft and the first gear and a second bearing coupled to the tube shaft and the second gear.
