A dolly comprising a chassis, a castor having a fork and a wheel rotatably mounted to the fork, and a fastener for fixing the fork of the castor to the chassis of the dolly. The fastener comprises a head which is shaped to the peripheral shape of the wheel of the castor.

A wheel bearing apparatus has an outer member, an inner member and double row rolling elements freely rollably contained between double row inner raceway surfaces and outer raceway surfaces of the inner member and the outer member. A plurality of bolt insertion bores, that fastening bolts pass through to fasten to the knuckle, are formed on the body mounting flange at plurality of positions circumferentially along the body mounting flange. The outer member is previously formed by hot forging. A seating surface for the fastening bolts is formed on an outboard-side surface of the body mounting flange by cold forging.

The present invention relates to attaching aerodynamic wheel covers to the wheel of a truck or other heavy duty vehicle, and to a method of installation that requires less tooling for installation while substantially completely covering the wheel.

A bicycle wheel spinner which is quickly and easily released from a hub and has an inner ring formed segments, with blades protruding from each segment. The segments each mount a roller wheel riding in a groove in a supporting hub. The segments are releasably fixed together in the groove. The spinner can be quickly removed by disassembling the inner ring segments. A locking mechanism allows the spinner to be locked to the hub or released to rotate independently.

An assembly tool for assembly and replacement of bolts on a wheel hub is revealed. The tool includes a first tool set and a second tool set. The first tool set has a base and a fastener. The base is a circular body with a receiving part. A pad is disposed on the receiving part and a bearing is arranged under the pad. The fastener includes a hexagonal head, an enlarged part, a cylindrical part and an axial hole arranged with a thread. The second tool set has a first arm and a second arm pivotally connected to each other. A wheel bolt is pressed into the wheel hub by the first tool set while the wheel hub is positioned by the first and second arms of the second tool set fastened with the wheel bolts of the wheel hub for convenient assembly of the wheel bolts.

A lug nut removal tool for applying rotational force on all lug nuts is shown having a circular frame member, a drive lug, a drive gear, and a plurality of transfer assemblies that each include an adjustable sockets. In one embodiment, rotation of the drive lug actuates the drive gear, thereby causing the each discrete transfer assembly to rotate. The transfer assemblies each include an adjustable socket for engaging a corresponding lug nut on a target wheel. In operation, each socket is first aligned with a corresponding lug nuts on a target vehicle wheel, locked in place, and then turned through the rotational force applied to the drive lug that is transferred to the its integrated transfer assembly by way of the drive gear.

The invention relates to a wheel bearing arrangement of a vehicle axle, including a wheel bearing, which contains at least two rolling element rows, for supporting a wheel hub which can be driven by a drive element. The rolling elements of the wheel bearing are guided in races of a stationary outer ring, the rotating wheel hub, and a separate inner ring which is allocated to the wheel hub. In the assembled state, the wheel hub of the wheel bearing arrangement and the drive element are operatively connected via gearing. The inner ring has a radially stepped inner contour, said inner contour having two diameters which differ from one another, and are received in a complementarily designed receiving area of the wheel hub. The position of the inner ring is fixed on the end face by a rolling riveted collar of the wheel hub.

A saddle riding type vehicle driven by a straddling rider, comprises a wheel including a wheel member having an annular rim, and a hub formed centrally of the rim to have a through hole formed at a center of rotation, a bearing attached to an inner circumferential surface of the through hole, and a tire attached to the rim; a wheel support for rotatably supporting the wheel with an axle inserted in the through hole; a sensor rotor mounted on the hub using the inner circumferential surface of the through hole as reference; and a wheel speed sensor for detecting rotation of the sensor rotor.

A railway wheel includes a rotation axis and a supporting disk which can be attachable on an axle at the rotation axis. The supporting disk can be coupled with a wheel rim for rolling on a rail. The wheel provides damping means of the rim with respect to the supporting disk which include elastic elements interposed between the disk and the rim, aside with respect to the median plane of the wheel. Each elastic element has its own geometrical axis and includes a first face facing the median plane of the wheel and a second face opposed thereto and facing the opposite part with respect the median plane of the wheel, so that the elastic element extends its thickness between the two faces. The first and second faces of each elastic element have the same concavity or convexity when considered in cross section in any plane containing the geometrical axis.

A method for manufacturing a vehicle wheel includes: a casting process of manufacturing the wheel in a one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, wherein the one-piece body further includes a resonance chamber forming groove; a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove; a flow forming process of bending the forming end to be seated on the stepped part; a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other; a fine machining process of removing the temporary flange; and a sound-absorbing hole machining process of forming a sound-absorbing hole for communicating between the resonance chamber and an interior space of a tire in the forming end.
