In various embodiments, the wheel retaining assembly includes a first wheel spacer configured to slide over the axle and to abut the outer wheel bearing, the first wheel spacer having an axially outward portion; and a second wheel spacer configured to slide over the axle, the second wheel spacer having an axially inward portion configured to engage the axially outward portion of the first wheel spacer.

A bicycle including a frame with a fork, the fork having dropouts between which a wheel axle is mounted. The wheel axle includes a sensor and/or an electric component arranged to be connected to a control element. A detachable electric connection is provided between the sensor and/or electric component and the control element. The detachable electric connection is positioned between the wheel axle and the thru-axle.

A device for rail vehicles comprising a predominantly hollow axle tube extending along a longitudinal direction (LR) and ending in a first wheel flange, and a wheel support extending opposite to the longitudinal direction (LR), comprising a wheel bearing, a second wheel flange and a mandrel as a cone, wherein the second wheel flange, the first wheel flange and a wheel arranged therebetween with a wheel hub are connected to each other via a flange connection, and wherein the mandrel as a cone is inserted from the wheel holder in a positive-locking manner opposite to the longitudinal direction (LR) through the wheel hub of the wheel into the interior of the axle tube and ends at the fastening element, which is arranged and cast into the axle tube and is connected thereto.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.

A wheel hub includes an inner hub part made of a first material and comprising a central portion formed to protrude in an axially inward direction and a flange portion formed to extend in a radially outward direction from the central portion; and an outer hub part made of a second material, which is lower in strength and lighter in weight than the first material, and configured to be integrally coupled with the inner hub part. The flange portion comprises a plurality of main extended portions in which a plurality of fastening holes are formed to penetrate in an axial direction while being arranged to be spaced apart from each other along a circumferential direction so that a wheel is mounted to the flange portion. The plurality of main extended portions are formed to extend along a plurality of virtual extension reference lines which extend in the radially outward direction.

A hub bearing unit includes an inner ring having inboard and outboard axial ends and a bearing inner race on an outer surface. An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis and the other ring is fixedly coupled with a frame. An annular displacement limiter extends radially from one ring and has a circumferential stop surface spaced radially from a surface of the other ring. The stop surface engages with the ring surface when the ring displaces radially relative to the other ring. A seal includes an annular sealing member coupled with one ring and is sealingly engageable with the limiter or is mounted on the limiter and sealingly engageable with one ring or a rigid seal member coupled with one ring.

A hub bearing unit includes an inner ring having inboard and outboard axial ends and a bearing inner race on an outer surface. An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis and the other ring is fixedly coupled with a frame. A plurality of rolling elements is rollable upon the inner and outer races. A displacement limiter extends radially from one ring and has a frustoconical stop surface spaced radially from a surface of the other ring. The limiter stop surface engages with the ring surface when the ring displaces radially and/or axially relative to the other ring to prevent brinelling impacts on the bearing races. Preferably, the displacement limiter is located axially between the rolling elements and the ring inboard ends.

A wheel bearing unit for a motor vehicle, having a wheel hub, a wheel bearing flange, and a wheel bearing for pivot mounting of the wheel hub on the wheel bearing flange. The wheel hub has a passage opening for mounting a shaft journal attached to the wheel hub by a screw connection element, and an inner toothing is formed, on an inner circumferential surface delimiting the passage opening, for rotationally fixed interaction with an outer toothing of the shaft journal, and the passage opening extends through a contact shoulder, which is formed so as to have contact with a contact surface of the screw connection element, with the formation of an orifice.

An “L-shaped” bushing assembly having a retainer pin sleeve and axle sleeve. An “L-shaped” retainer pin is fitted to the retainer pin sleeve and provides a handle piece that projects through the walls of the bushing assembly and wheel that is maneuverable to retract and release the retainer pin and wheel from a grooved axle. The L-shaped retainer pin and bias spring are alternatively mounted in single and multi-channel slots to facilitate retainer pin mounting and/or containment of the retainer pin at a storage position. The retainer pin sleeve slots and/or a transverse open slot facilitate cooperation of a wheel removal tool with the retainer pin(s).

A wheel end assembly includes a hub connectable with a wheel and having a bore for receiving a shaft. An inboard bearing within the bore includes an outer ring coupled with hub, an inner ring within the outer ring and rolling elements. A seal assembly is coupled with the inner ring and retains the inner ring within the outer ring when the end assembly is separate from the shaft. An outboard bearing within the hub bore includes an outer ring coupled with the hub, an inner ring within the outer ring and rolling elements. A nut assembly is disposed adjacent to the outboard bearing and includes a nut threadably engaging the shaft. A retainer retains the nut assembly adjacent to the outboard bearing to limit axial displacement of the outboard inner ring to maintain the inner ring within the outer ring when the wheel end is separate from the shaft.
