A motor vehicle wheel bearing assembly includes a hub configured to be supported by at least one rolling-element bearing and to provide a seat for a wheel. The hub includes a first hollow-cone-shaped element manufactured from light metal and having a first axial end section having a first diameter and a second axial end section having a second, larger, diameter and at least one bearing raceway or raceway support at the first axial end section. The hub also includes a second element extending radially from an end of the first hollow-cone-shaped element, the second element having a radially inner section and a radially outer section. The second axial end section of the first element is connected to the radial outer section of the second element, for example, at a joint.

A method of adjusting preload on a bearing assembly of a wheel mounted on an axle or spindle with a lock nut includes mounting a preload adjustment tool onto a threaded axle or spindle. The load on the bearing assembly is increased using the tool. The wheel on the axle or spindle is rotated to set the bearing assembly. The load on the bearing assembly is decreased to a desired maximum preload on the bearing. After decreasing the load on the bearing assembly to a desired maximum preload, the lock nut is tightened by hand until the lock nut cannot be further tightened. The lock nut is loosened by rotating the lock nut to a preferred location where a guide mark on the tool aligns with one mark on the lock nut located closest to the guide mark wherein a resultant preload on the bearing assembly is within a preset range from the desired maximum preload.

A wheel bearing having a cup, a cone and a washer. The cone is of a complementary shape to the cup and the washer abuts a surface of the cone. Each of the cup, the cone and the washer are made from a self-lubricating polymer.

A levitating bicycle hub coupling structure using a magnet in the internal contact structure is provided. The levitating bicycle hub coupling structure in which a non-contact type structure in a levitated form is provided to reduce friction enables the position of a hub inner shaft member for transmitting the load of a user to an inner bearing part to be changed to an upper or lower preset position, and fixes the shaft member at a changed position so as to offset the load applied to the shaft member by the repulsive force of the magnets, such that the load is not applied to the bearing parts positioned at both sides of the shaft member or is significantly reduced so as to improve rolling performance, and thus riding of the bicycle becomes smoother and easier.

In one aspect, a lock nut is provided that includes a washer, a threaded body, and an actuator that are distinct from one another. The washer is configured to form a non-rotatable connection with a vehicle spindle. The threaded body has threads to engage threads of the vehicle spindle. The actuator has a rotary drive structure and is configured to be turned in a tightening direction to cause turning of the threaded body in the tightening direction relative to the washer. The lock nut includes a lock operably coupled to the actuator and configured to inhibit turning of the threaded body in a loosening direction relative to the washer. The actuator is configured to be turned relative to the threaded body in the loosening direction to disengage the lock and permit turning of the threaded body in the loosening direction relative to the washer.

A connecting arrangement is provided between joining partners which are braced separably against each other in the chassis region of a vehicle, wherein the joining partners are braced against each other via their contact surfaces by at least one releasable fastening element. Hard particles are applied to the contact surface at least of one of the joining partners before the production of the connecting arrangement and therefore before the bracing mounting of the joining partners and of the fastening element. The hard particles at least partially project into the respectively other contact surface as a result of the bracing mounting. The hard particles are applied so as to be at least approximately abrasion-proof, for example by a blasting process.

A unitized wheelend is provided. The unitized wheelend includes a hub having an inboard side bounded by an oil seal and an outboard side bounded by a retainer releasably coupled to the hub. The unitized wheelend assembly includes an inboard bearing assembly, a spacer, an outboard bearing assembly, and a spindle nut assembly.

A flanged wheel hub for wheel hub bearings, the wheel hub having a flange provided with a plurality of threaded through holes and, for each threaded through hole, a respective radial arm, which has a respective axial thickness (SAB) to act as a strengthening element for the flange, at least at the position of the threaded through holes, the wheel hub being produced by forging with the flange and the arms made in one piece, and also having, for each threaded through hole, an annular boss, which is also forged in one piece with the wheel hub and is arranged around, and penetrated by, the corresponding threaded through hole for the purpose of increasing the mechanical strength characteristics of the wheel hub.

An Automatic Tire Inflation System (ATIS) for use with a vehicle includes a controller, valves controlled by the controller and, for at least one drive axle having inner bearings and outer bearings, a channel formed in a spindle, first hosing coupling controlled by the controller to the channel formed in the spindle, a channel formed in a hub, a rotary air seal coupling the channel formed in the spindle to the channel formed in the hub, and second hosing coupling the channel formed in the hub to at least one wheel. The rotary air seal may transition from a sealed state that forms a seal between the spindle and the hub to support air flow between the channel formed in the spindle and the channel formed in hub and reside in an unsealed state to negate the seal between the spindle and the hub.

A hub-bearing unit is provided with a hub, rotatable, with an axially outer flange portion configured for engagement with a rotatable element of a motor vehicle, a bearing unit provided with a fixed radially outer ring, configured for engagement with a fixed element of the motor vehicle, a first, axially outer, crown of rolling bodies, and a second, axially inner, crown of rolling bodies, interposed between the radially outer ring and the hub. The radially outer ring is held in position with respect to the knuckle by a stop ring, positioned on the axially inner side of the radially outer ring in a seat formed on the radially outer ring.
