A system for person mobility devices such as wheelchairs. The system includes a personal mobility apparatus having a wheel support portion, and an axle engaging portion that is attachable to and detachable from the wheel support portion. The wheel support portion may be a body portion or a frame portion of the personal mobility apparatus that is formed separately to the wheel support portion. The wheel support portion may be shaped so as to fit a complementary shape of the axle engaging portion. The system allows for customization of a mobility apparatus for a particular application or user by adjusting the position or orientation of the wheel axles.

Aerodynamic wheel covers may include a hub assembly coupled with a hub of a large vehicle, such as a truck. A base assembly may be coupled to the hub assembly, and a disk assembly may be coupled with the base assembly such that removal and installation of the disk assembly may be accomplished without tools.

A vehicle spindle and a method of attaching the spindle to a portion of an axle half shaft housing. The spindle has an inner surface, an outer surface, one or more bearing journals on the outer surface of the spindle and a radially protruding portion circumferentially extending from at least a portion of the outer surface of an axially inboard end portion of the spindle. Prior to attaching the spindle to the axle half shaft housing, the one or more bearing journals are ground, a clocking angle for the radially protruding portion of the spindle is determined and the spindle is aligned to the determined clocking angle. Once the spindle is aligned to the determined clocking angle, the axially inboard end portion of the spindle is attached to an axially outboard end portion of the axle half shaft housing using one or more welds.

A hub for bicycles including a hub shell which is rotatably supported relative to a hub axle, a rotor rotatably supported relative to the hub axle by means of two rotor bearings, and a freewheel device having two interacting freewheel components namely, a hub-side freewheel component and a rotor-side freewheel component. The two freewheel components each include axial engagement elements and they are movable relative to one another in the axial direction between a freewheel position and an intermeshing engaging position. Rolling members are provided for defined accommodation in the hub-side freewheel component to support the hub shell relative to the hub axle. An attachment portion and a centering portion are configured in the hub shell and an attachment area and a centering area are configured on the hub-side freewheel component. The attachment area is connected with the attachment portion and the centering area is centered on the centering portion.

A hub-bearing assembly for rotatably mounting a motor vehicle wheel on a suspension strut having a wheel hub to support the wheel of the vehicle and having an axial shoulder, a bearing unit providing a radially outer stationary ring constrained to the strut; a first radially inner rotating ring mounted on the hub, and a second radially inner rotating ring defined by the hub, two rows of rolling bodies interposed between the radially outer stationary ring and the two radially inner rotating rings inside a first raceway and a second raceway formed, respectively, the first inner ring providing a substantially non-deformable Hertzian portion, on which is formed the second raceway, and an accumulation portion integral with the Hertzian portion and interposed between the Hertzian portion and the axial shoulder for accumulating elastic energy during cold deformation to obtain the rolled edge.

Disclosed are a method of configuring an additional air chamber member on an outer circumferential surface of a well portion of the vehicle wheel as a Helmholtz resonator in a tire air chamber, comprising: preparing a plurality of additional air chamber members for each size of the vehicle wheel, each additional air chamber member corresponding to a different resonance frequency; and selecting one of the additional air chamber members with the corresponding resonance frequency from the additional air chamber members in accordance with a size of a tire used in combination with the vehicle wheel and an additional air chamber member information system using the method.

The present invention relates to an axle unit comprising an axle tube and an axle stub, wherein the axle stub is formed to be rotationally symmetrical with respect to a stub axis in some regions and has a channel which extends substantially parallel to the stub axis, wherein the axle stub has a first connection portion which has an engagement geometry for fluid-tight connection to the channel, wherein the axle tube is formed to be substantially rotationally symmetrical about a tube axis and wherein the axle tube and the axle stub are fixed on/to one another by way of a cross-member in such a way that the tube axis and the stub axis are spaced from one another.

An assembling method includes fitting an entire range of the guide portion to the stem section with a gap therebetween, and inserting a bolt from an outboard side through a bolt insertion hole formed in the hub wheel. In this state, a maximum inclination angle of the bolt with respect to the hub wheel is set to be larger than a maximum inclination angle of the outer joint member with respect to the hub wheel. The method also includes connecting the bearing and the constant velocity universal joint to each other by threadedly engaging and fastening the bolt into a bolt hole formed in the stem section.

An automatic carving device for a wheel, including a rack, a chassis, a lifting cylinder, brackets, bearing blocks, linear bearings, mounting plates, guide shafts, a lifting shaft, a servo motor, a synchronous pulley, a connection plate, a synchronous belt, a synchronous pulley, a pedestal, a connection shaft, a servo motor, a shaft sleeve, a lower end cover, a connection shaft, a shaft sleeve, and an oil cylinder. The automatic carving device for the wheel can automatically carve characters on the wheel, meanwhile it also has the characteristics of simple structure, convenience for manufacturing, stable performance and high precision that can meet the machining requirement, and can also meet the requirement of automatic production.

A wheel balance device for a motorcycle attachable to a motorcycle wheel rim. The wheel balance device includes a pedestal vertically attachable to a crown of an inner rim of the motorcycle wheel rim in a position between a pair of spokes on opposite side of the crown and having a first end attachable to the crown, a second end, an outer wall therebetween, a transverse orifice therethrough, and a longitudinal channel continuously disposed therethrough. A weight body, having an arc substantially conforming to a shape of the inner rim, is insertable through the transverse orifice and has a hole transversely disposed therethrough, which is alignable with the channel when the weight body is inserted into the transverse orifice. A fastener, which engages both the channel pedestal and the hole of the weight body, secures the weight body to the pedestal.
