A depth gauge wheel for a row planter. The depth gauge wheel sets the planting depth for the seeds planted by the row planter. The depth gauge wheel sets planting depth by setting the cutting depth of the disk opener of the row planter. The depth gauge wheel also scrapes mud from the disk blade of the disk opener. The depth gauge wheel includes a rim, a tire attached to the rim and a ring attached to the rim. The tire contacts the surface of the ground to set the cutting depth of the disk opener and the ring scrapes mud from the disk blade of the disk opener.

An insert rubber for improving aerodynamics of a tire and an installation method thereof, and provides an insert rubber for improving aerodynamics of a tire and an installation method thereof, in which, by eliminating a space which is located between a bead of a tire and a flange of a rim, airflow is prevented from being introduced between the bead and the flange while a vehicle travels, and the space between the bead and the flange is filled with the insert rubber, thereby preventing turbulence from being generated in the space between the bead and the flange.

A marked wheel rim is provided, including: a rim body and a mark. The rim body includes an outer surface. The mark is embedded on the outer surface and includes an outer peripheral edge adjacent to the rim body. The outer peripheral edge is non-protrusive beyond the outer surface. A method for manufacturing the marked wheel rim is further provided.

The application relates to a wheel hub for vehicle, which comprises a flange, a rim, a spoke, a central hole, and bolt bores distributed around the central hole. According to the disclosure, the flange on the wheel front side is affixed with an extension part comprising a radial extension magnitude extending to the outer periphery of the wheel hub and an axial extension magnitude extending to the wheel front side, the extension part comprises a plurality of sections circumferentially distributed along the flange, so as to form on the wheel front side an envelope circle having a diameter size increased by twice the radial extension magnitude. The present disclosure further satisfies the additional needs of the user with respect to the overall design of the wheel.

A rim cover assembly having a waterproof structure according to an embodiment of the present invention includes a rim of which an outer wheel is surrounded by a tire, wherein a shaft passes through and is connected to a center of the rim, a cover coupled to the rim to seal an interior of the rim, tire separation prevention steps formed on the rim and the cover to prevent separation of the tire, and a bolt coupling portion which couples the cover and the rim, wherein the tire separation prevention steps include a first tire separation prevention step, which is integrally formed with the rim and protrudes from one side of the rim and a second tire separation prevention step integrally formed with the cover coupled to the other side of the rim, and the bolt coupling portion may be formed in the second tire separation prevention step.

An aircraft wheel hub protector is adapted to engage an aircraft wheel including an aircraft tire on a rim. The aircraft wheel hub protector having two or more cover sections with a protective protrusion and coupling mechanism guide extending from the a first cover section and passing through a bearing race and internal surface within a hub of the rim of the aircraft wheel in such a fashion so as to provide a void within the protective protrusion. The second cover section is engaged with an opposed side of the aircraft wheel from the first cover section. A coupling mechanism passes through the void in the protective protrusion without having contact with the bearing race and internal surfaces within the hub of the rim and coupling the first cover section and securing the aircraft wheel hub protector to the aircraft wheel.
