Systems, apparatus, devices, brackets, assemblies, and methods for a wheel hub with interchangeable caps for changing the appearance of wheels having exposed lug nuts about a center hole. A bracket having both a small cap and a large cap can be used on an existing wheel which exposes a center hole and the lug nuts. A smaller cap can be used to cover only the center hole of the wheel. A larger cap can be used to cover both the center hole and the exposed lug nuts on the wheel. The bracket is a base that allows for either a small cap or large cap to be interchangeably used to change the exterior appearance of the wheel. The bracket can be integrated with the wheel, or be attachable onto the wheel.

A wheel for a vehicle is disclosed. The wheel comprises a central portion attachable to a vehicle hub and a rim arranged radially outside the central portion for supporting a wheel tire. The central portion has a series of cavities configured to receive a corresponding adapter. A cavity of the series of cavities has a through hole. The through hole is aligned in an alignment direction for alignment with a through hole of a corresponding adapter for traversal by a mounting element to attach the central portion to the vehicle hub. The cavity is configured to receive the corresponding adapter in a unique rotational position with respect to the alignment direction. The cavity includes first and second cylindrically shaped and axially aligned volumes. The first volume is bounded by a first receiving wall portion that extends substantially parallel to a front side surface of the central portion. The second volume extends from the first volume towards a back side surface of the central portion. The second volume is located radially within a radial outer periphery of the first volume.

A caster yoke for use in the manufacture of a set of wheeled caster assemblies wherein each caster assembly of the set of caster assemblies is capable of having unique functional capabilities relative to each other caster assembly of the set arising from different combinations of caster components (selected from a set of pre-determined of caster components) being mountable on each respective caster yoke of the set of wheeled caster assemblies. To this end, the caster yoke is provided with all of the mounting features necessary to selectively mount all of the respective caster components of the pre-determined set on the caster yoke, such that the same form of caster yoke may be used without modification as a mounting frame to create a set of caster assemblies having different functionalities, significantly reducing design, production and inventory costs for the set of caster assemblies.

A tire rim structure including an annular inner ring (2) provided on the inner ring of a tire body (1) and a circular outer ring (3) provided on the outside of the tire body (1), fixedly connected to the annular inner ring (2), and formed by stamping. The annular inner ring (2) includes an annular inner ring body (21) formed by extrusion, an annular left ring (22) provided at one side of the annular inner ring body (21) and formed by extrusion, and an annular right ring (23) provided at the other side of the annular inner ring body (21), connected to the circular outer ring (3), and formed by extrusion. A shaft hole (31) is provided at the middle part of the circular outer ring (3). By breaking down a tire rim into the annular inner ring body (21), the left ring (22), the right ring (23), and the outer ring (3) connected to the right ring, each of the components composing the tire rim can be processed and formed via extrusion or stamping processes, this provides increased consistency compared with an existing tire rim that is integrally processed and formed via a casting process, thus allowing for increased structural strength and simplified manufacturing process.

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.

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.
