A precision cantilever bearing assembly to align the output hubs of an axle assembly which includes a cantilever bearing positioned in one hub bore. The cantilever bearing has an axially extending bore. A shaft plug having an axially extending bore is positioned in the other hub bore. A shaft is positioned in and rotates and counter rotates in the cantilever bearing axially extending bore and is fixed in the shaft plug bore to facilitate alignment of the hubs.

A domino-type torque generator includes a base member, and a plurality of toppling members pivotally connected to the base member. Each toppling member is pivotable from an upright position to an inclined position, or from the inclined position directly to an opposite inclined position, about a torque shaft extending transversely through a lower end portion of each toppling member. One end of each torque shaft is provided with a pinion. A first differential gear is connected to the pinions to accumulate torques applied on the torque shafts by toppling of the toppling members. A rotating cage of the first differential gear is the output, and is directly or indirectly connected to one of the side gears of the next differential gear, which is used to accumulate output torque from the first differential gear. A drive mechanism is configured to repeatedly drive the toppling members to topple, thereby continuously generating torques.

An electric drive transmission system includes a disconnecting differential. The disconnecting differential comprises a first one-way clutch, a second one-way clutch and an interruption device. The first one-way clutch and the second one-way clutch have opposite locking directions and are coaxially sleeved between a planet carrier and a differential housing. The interruption device comprises a power section and an interruption section, wherein the power section is located on an inner wall of a reduction gearbox, and wherein the interruption section is located on the differential housing and can shift, under the action of the power section, all rolling elements of the one-way clutch locked in a forward rotation coasting condition, thereby realizing selective releasing of the locking function of the one-way clutch.
