An axle assembly having an axle housing, a wheel end cover and an axle shaft. The axle housing has a tubular member with an end flange coupled thereto. A pair of axle bearings are mounted to the axle shaft and the end flange and support the axle shaft for rotation relative to the axle housing. The wheel end cover is mounted to the end flange and carries a seal that is engaged to the axle shaft. A method for assembling an axle assembly is also provided.

The present invention relates to a hub for a bicycle, having a hub axle, a hub sleeve which is mounted rotatably on the hub axle via a bearing arrangement, a driver which is mounted rotatably on the hub axle via a bearing arrangement and is coupleable to the at least one hub sleeve in a torque-transmitting manner, wherein the bearing arrangement has at least one axially inner bearing and at least one axially outer bearing. At least one fastening element is provided, which fixes at least the inner bearing of the bearing arrangement in its predetermined position on the hub axle by a local or sectional enlargement of the cross section of the hub axle.

Disclosed are a caster assembly and a parking robot including the same. The present embodiment relates to a caster assembly and a parking robot including the same, the caster assembly including a bearing configured such that an inner race rotates relative to an outer race, a bearing casing to which the bearing is fixedly coupled so that at least a part of the outer race is supported on an inner circumferential surface of the bearing casing, a bearing upper cover provided to surround at least a part of the inner race, except for a bottom surface of the inner race, and rotatably coupled to the inner circumferential surface of the bearing casing, a bearing lower cover provided to support at least a part of the bottom surface of the inner race and fastened to a lower side of the bearing upper cover, and a wheel protruding downward from a top surface of the bearing upper cover and rotatably coupled to the bearing upper cover or the bearing lower cover.

A bearing cassette assembly may include a cassette securable to a chassis of a vehicle, and a cam securable within the cassette in one of a plurality of radial positions relative to the cassette, wherein the cam is configured to receive a first vehicle axle bearing assembly. When the cam is moved into one of a plurality of radial positions, the first vehicle axle bearing assembly is moved relative to a second vehicle axle bearing assembly of the vehicle.

A sprocket assembly includes a sprocket including a center orifice and a bearing located in the center orifice with an outer part of the bearing fixed in relation to the sprocket. The sprocket assembly also includes a dust cover fixed in relation to an inner part of the bearing. An outer cover diameter of the dust cover is bigger than an outer bearing diameter of the bearing, so that an outer periphery of the dust cover extends radially past the outer part. The sprocket also includes an impeller arranged at the outer periphery of the dust cover. The impeller is fixed in relation to the sprocket.

A rotating bicycle joint assembly includes a rotating joint part, a fixed joint part, and a bearing located between the rotating joint part and the fixed joint part. An outer part of the bearing is fixed in relation to one of the rotating joint part or the fixed joint part. An inner part of the bearing is fixed in relation to the other of the rotating joint part or the fixed joint part. A dust cover has an outer cover diameter that is bigger than an outer bearing diameter of the bearing, so that an outer periphery of the dust cover extends radially past the outer part. The rotating bicycle joint assembly also includes an impeller arranged at the outer periphery of the dust cover. The impeller is fixed in relation to the rotating joint part. The dust cover is fixed in relation to the inner part of the bearing.

A split torsion axle is configured to provide the advantages of a torsion axle while also allowing for the independent adjustment of related wheel assemblies positioned on opposite ends thereof. The split torsion axle also provides for additional stability provided by having a continuous axle member spanning the width of the trailer or vehicle upon which the split torsion axle is deployed. To provide these capabilities, the split torsion axle comprises a first torsion axle beam and a second torsion axle beam, which are rotatably coupled to one another by a central joint. The central joint comprises a first spindle coupled to the first torsion axle beam, a second spindle coupled to the second axle beam, and a bearing assembly rotatably coupling the first and second spindles to one another. Both the first torsion axle beam and the second torsion axle beam are configured to be coupled to respective wheel assemblies.
