An image board for a rotary wheel which is mounted on a rotary wheel of a vehicle and displays a stationary image regardless of the rotation of the rotary wheel, the image board including: a base plate which is uprightly arranged on the outer portion or the inside of a wheel frame provided on the rotary wheel and mounted to be independently rotatable with respect to the wheel frame, and on one side or both sides of which a predetermined image is arranged, the base plate including a chamber on which a space is formed to be extended along the circumferential direction with respect to a rotational axis; a main weight which is fixedly mounted on the bottom of the base plate and applies a load to the bottom of the base plate; and a compensation weight which moves within the space as the main weight rotates in any direction and applies a load to the main weight so that the main weight returns to the original position thereof, the compensation weight being arranged within the space.

The present invention provides a method for color register spraying of a hub, which includes machining and turning for glossy finish after spraying a black paint on the surface of a hub, and then spraying a color transparent paint onto the hub. The method provided by the invention achieves a spraying-based color register effect through spraying of the color transparent paint, which greatly improves the production efficiency and is available for batch production.

A wheel cover for a wheel of a vehicle may include a cover portion removably operably coupleable to the wheel via a first set of retention tabs, the cover portion may be centered at an axis of rotation of the wheel and may cover spokes of the wheel, and a button cap removably operably coupleable to the wheel cover via a second set of retention tabs, the button cap may be centered at the axis of rotation of the wheel. The first set of retention tabs may be urged by a wire ring into engagement with a lip of the wheel, the lip may extend around the axis of rotation at a center bore of the wheel. The second set of retention tabs may insert into corresponding ones of a set of retention slots disposed in the cover portion.

A hubcap central locking mechanism which includes a hubcap, a hubcap locking member and a decorative cover. The hubcap includes a built-in screw connecting with a interlinked pressing member for fixedly installing an outer supporting member; a primary member of central locking mechanism is installed on the outer surface of a side wall of the outer supporting member, some clamping bead holes for placing clamping beads are set at the bottom edge of the inner wall of the primary member, a side wall of the primary member of central locking mechanism is provided with threads for spirally installing the locking member of central locking mechanism, a wheel hub silicone gasket is installed at the bottom of the locking member, and a spring is installed in the middle space between the bottom of the interlinked pressing member and the top of the outer supporting member.

An adapter assembly that allows a wheel cover to be attached to a wheel has an inner device which locks through a central hole in the cover to an outer device insert. The inner device removably locks to a vehicle wheel, A The cam trapping cage secures a locking cam to a main wheel mounting clip with prongs that snap over the lip of the cam trapping cage, securing the assembly to the wheel hub centerbore. The locking cam physically blocks the mounting clip to keep them from backing out of their secured position. A silicone o-ring lies between the cover and the wheel lip, keeping the cover under constant tension for secure connection. Outside the cover, a billet hex nut and a hex nut o-ring reduces vibration and connects the cover to the inner device. A cap base with cam safety also prevents the locking cam from backing out.
