An axle assembly for a vehicle. A movable housing is movably positioned within a closed channel defined by a central housing. The movable housing moves the axle assembly between a retracted configuration and an extended configuration. A mounting assembly may be coupled to and spaced from the movable housing and slidably positioned adjacent the central housing. A steering actuator is coupled to a steering arm and the mounting assembly such that the steering actuator moves as a unit. A track assist bracket may be fixedly coupled to the central housing and define a gap sized to slidably receive a mounting plate of the mounting assembly. A bushing may be disposed on each wall of a telescoping portion of the movable housing. A bellows may be provided to enclose exposed portions of the bushings in the extended configuration. Methods of adjusting the track of the axle assembly are also disclosed.

The steering function-equipped hub unit includes: a turning shaft-equipped hub bearing (15) including an inner ring, an outer ring, and rolling elements in double rows interposed between the inner ring and the outer ring, the turning shaft-equipped hub bearing having a turning shaft extending in a vertical direction; a unit support member (3) rotatably supporting the turning shaft-equipped hub bearing (15) about a turning axis of the turning shaft; and a steering actuator (5) configured to rotationally drive the turning shaft-equipped hub bearing (15) about the turning axis (A). The unit support member (3) and the steering actuator (5) include a flange (3a) and an end portion (25Aa), respectively, to be removably fixed to a knuckle (6) which is a chassis frame component of a vehicle.

To provide a hub bearing that is capable of reducing a delay in a response of the hub bearing and improving a steering stability of a vehicle. A hub bearing 1 includes an outer ring 2 serving as a stationary side raceway ring, a hub wheel 3 and an inner ring 5 serving as a rotatable side raceway ring, balls 4 serving as a plurality of rolling elements disposed between a raceway surface of the stationary side raceway ring and a raceway surface of the rotatable side raceway ring, and grease that lubricates a rolling contact part between each of the raceway surfaces and the rolling elements. The surface roughness of at least one raceway surface selected from the raceway surface of the stationary side raceway ring and the raceway surface of the rotatable side raceway ring in the rolling contact part is 0.03 μmRa or less. Further, the grease has a traction coefficient in the rolling contact part of 0.04 or less at 40° C. when a vehicle speed is 20 km/h or more.

The invention relates to a method for producing a bent torsional profile comprising the following process steps: a) provision of a plate made of planar sheet metal, b) reshaping of the plate through the introduction of a bent trough oriented in the longitudinal direction of the plate in a central length portion (6) of the plate at a distance from the front edges of the plate, forming legs between the trough and the longitudinal edges of the plate, c) reshaping of the legs in such a manner that an open profile is created, d) reshaping of the legs in such a manner that a hollow profile is produced, wherein a longitudinal gap is formed between the two legs over the entire longitudinal extent thereof and wherein an air gap is created between the legs and the trough in the region of the trough, e) joining of the two legs over the entire longitudinal gap.

An axle system includes an axle stub and a clamping unit, the axle stub being formed in a substantially rotationally symmetrical manner about a stub axis, the clamping unit in an assembled state transmitting a clamping force to the axle stub, the clamping unit and the axle stub in the assembled state being secured non-positively to prevent movement relative to one another.

An example apparatus includes a base including a first locking surface, a wheel including an axle, and a locking body at the axle of the wheel to rotate with the wheel. The locking body includes a second locking surface to engage the first locking surface of the base to lock the wheel. The apparatus further includes a plate spring that captures the axle of the wheel to allow wheel to rotate. The plate spring urges the second locking surface of the locking body against the first locking surface of the base to lock the wheel. The plate spring is to deflect under application of an external force to separate the second locking surface of the locking body from the first locking surface of the base to allow the wheel to roll.

A state determination device for a hub unit bearing includes: a holding unit that holds reference information of magnetic characteristics at a predetermined position in the vicinity of a flange portion included in the hub unit bearing; an acquisition unit that acquires measurement information of the magnetic characteristics at the predetermined position of the hub unit bearing; a derivation unit that derives a change amount between the reference information held by the holding unit and the measurement information acquired by the acquisition unit; and a determination unit that determines a state of the hub unit bearing based on the change amount derived by the derivation unit. The predetermined position is a position at which the magnetic characteristics vary with a stress change with respect to the flange portion.
