    摘要： An axle assembly with a housing, a pinion, a ring gear, a bearing and a pair of shafts. The pinon is mounted to the housing for rotation about a first axis. The ring gear is received in the housing and meshingly engaged with the pinion. The bearing supports the ring gear for rotation relative to the housing about a second axis and also handles thrust loads between the housing and the ring gear that are directed (in both directions) along the second axis . The bearing has a plurality of bearing elements and is abutted against a shoulder formed on the housing that is positioned along the second axis between the first axis and the bearing elements. The differential assembly has a differential case, which is coupled to the ring gear for rotation therewith, and a pair of output members that are coupled to the shafts for common rotation.

    摘要： A vehicle final reduction gear unit includes a first friction brake positioned between a right case member which is a stationary body and a differential case which is a rotating body for applying a pressing force in an axial direction to generate a frictional force in order to put a brake on the differential case. A second friction brake occupies an area between the differential case and the right wheel and applies a pressing force in the axial direction to generate a frictional force in order to use a rotational difference to put the differential mechanism into a lock state. The second friction brake is placed within the radius of the first friction brake. A reduced size is accomplished and the final reduction gear unit can be reduced in length in the vehicle-transverse direction. Thus, a vehicle final reduction gear unit allowing a reduction in size can be provided.

    摘要： A differential lock mechanism is provided for use in an axle assembly having a differential, an input member and first and second axles. A lock sleeve is co-axially disposed about the first axle, with the lock sleeve being rotatable with the first axle and laterally movable relative to the first axle. A lock collar is co-axially disposed about the lock sleeve and is laterally movable between outboard and inboard positions. A biasing member biases the lock sleeve toward the rotatable carrier and a lock fork is engaged with the lock collar. The lock fork is operable for moving the lock collar between the outboard and inboard positions. The lock collar is disengaged with the rotatable carrier when the lock collar is in the outboard position and is engaged with both the rotatable carrier and the lock sleeve when the lock collar is in the inboard position.

    摘要： A pinion shaft is supported in a housing by two tapered roller bearings which are arranged separately from each other in an axial direction, and these two tapered roller bearings are lubricated with lubricating oil in the housing in oil bath lubrication method. A labyrinth forming member in a disc-like shape is disposed with respect to a backward tapered roller bearing out of the two tapered roller bearings, on an end face at a small diameter side of an inner ring thereof in a press-contact manner, so as to be opposed to a rib part which is formed inwardly in a radial direction at a small diameter end of a cage. In this manner, a labyrinth structure for restricting a flow of the lubricating oil is formed between the rib part at the small diameter end side of the cage and the labyrinth forming member.
