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 assembly having a spigot bearing assembly. The spigot bearing assembly may extend between a motor housing and a rotor output flange that may be fixedly mounted to a rotor. The spigot bearing assembly may rotatably support the rotor output flange and may inhibit deflection of the rotor. A spigot bearing biasing member may exert a biasing force on the spigot bearing assembly.

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.

A transaxle includes: an axle housing in which an input gear is rotatably supported; a differential casing that is contained in the axle housing while being rotatably supported relative to the axle housing; first and second side gears as a pair of spur gears that are contained in the differential casing, coaxially arranged, relatively rotatable with each other, and rotatable relative to the differential casing; a group of pinions as spur gears that are rotatably supported, in the differential casing, by rotational shafts that are in parallel with axes of the first and the second side gears in the differential casing, the group of pinions transmitting power between the first side gear and the second side gear; and a final gear having a ring shape that is contained in the axle housing, meshes with the input gear, incorporates the differential casing, and is relatively unrotatably coupled to the differential casing.

An axle assembly having a differential carrier, a differential assembly, a drive pinion, a spigot bearing, and a lubricant deflector. The drive pinion has a spigot. The spigot is rotatably supported by the spigot bearing. The lubricant deflector is mounted to the differential carrier and directs lubricant to the spigot bearing.

A vehicle includes three pairs of wheels, each pair being spaced apart in a right-left direction, three differential gears, respectively corresponding to the three pairs of wheels, and an engine that generates a rotation to be transmitted to the three pairs of wheels through the three differential gears. The engine is located rearward of a front differential gear that is any one of the three differential gears and is fixed to the front differential gear.

A gear module includes a rotating cylinder, a first planetary gear set, a second planetary gear set, a concave-convex structure, and a limit bearing set. The first planetary gear set is accommodated in the rotating cylinder and includes a driven gear; the second planetary gear set includes a positioning frame, second planetary gears pivoted to a positioning frame, a driven gear engaged with the second planetary gears, and the positioning frame has a through hole; the concave-convex structure includes a convex column extended from the rotating cylinder and a concave hole formed on the positioning frame, the convex column is plugged into the concave hole; the limit bearing set includes a first ball bearing sheathing the driven gear and mounted between the driven gear and the through hole, and a second ball bearing sheathing the convex column and mounted between the convex column and the concave hole.

An axle assembly having a drive pinion that may be rotatably supported by first and second sets of roller bearing elements. A preload element may exert a preload force on at least one of the first and second sets of roller bearing elements. The preload element may be disposed on the drive pinion in an inboard direction from the yoke.

Provided herein is a tandem axle system including a top-mount forward axle assembly, a rear axle assembly and an intermediate drive shaft assembly.

An axle assembly having a preload mechanism. The preload mechanism engages a bearing assembly and includes a preload element and an adjuster element. The preload element is disposed inside a housing and is rotatable about an axis. The adjuster element engages the preload element and is moveable to actuate the preload element and exert a preload force on a bearing assembly. The adjuster element is accessible from outside of the housing.
