The invention relates to a cover for a wheel rim of a wheel, more particularly for a wheel rim of an alloy wheel for motor vehicles, wherein the wheel rim has a rim inner well, which merges into a rim inner flange that is arranged facing a motor vehicle when the wheel is mounted, and as a result, the wheel rim has an uninterrupted contoured section on the axially inner side. The invention, the rim inner flange can be sealed in the axial direction (a) by means of the cover. The invention further relates to a wheel, particularly having such a cover.

The vehicle wheel (1) of the present invention is characterized by including: a main body (13) which forms a sub air chamber (SC) in a space surrounded by a top plate (25a), a bottom plate (25b) and a pair of side plates (25c, 25d); and edge portions (14a, 14b) which extend from the main body (13), and are respectively fitted into a pair of grooves (17a, 17b) formed in a well portion (11c) so as to attach the main body (13) to the well portion (11c). The edge portions (14a, 14b) respectively extend from the joints (25e, 25f) between the top plate (25a) and the side plates (25c, 25d).

An adapter for a rolling assembly comprising a tire having two beads (B), a rim (J) with two rim seats (7), said adapter connecting one of the beads and the rim. The adapter has an axially inner end (10) comprising inner reinforcer element (16), and an axially outer end (15) comprising outer reinforcer element (15), respectively mounted on a rim seat (7). Body (11) connects said outer end (9) to said inner end (10). Main reinforcement connects said outer reinforcer (15), and said inner reinforcer (16), a substantially cylindrical adapter seat (18) receiving one of said beads (B), an adapter bearing face (21) substantially contained in a plane perpendicular to the rion otataxis. The reinforcer element (15) of the axially outer end (9) is entirely situated axially outside the bearing face (21), and in that the body (11) comprises, opposite the adapter seat (7), an annular seat reinforcer (19).

The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

A wheel rim having a reinforcement structure is disclosed. The wheel rim has two connected side walls and a connecting wall. An outer peripheral edge is connected to each side wall. Either end of the connecting wall is connected to a connecting edge. The outer peripheral edge intersects the connecting edge. A joint portion is formed at an intersection of the connecting wall and the connecting edge. The joint portion is spaced from the corresponding side wall. A reinforcement edge is connected between each side wall and the connecting wall. A hollow support region is enclosed by the corresponding side wall, the outer peripheral edge, the connecting edge, the connecting wall and the reinforcement edge. The joint portion and the side wall do not concentrate external force on the side wall, thereby achieving the effect of reducing the external force acting on the wheel rim and dispersing the force.

A wheel is provided that combines the principles of a beadlock wheel and a liner wheel for improved performance in motor racing, in particular drag racing. The wheel has beadlock rings that fasten to inner and outer rims of the wheel to secure an outer tire, and the wheel has knurls interior to the inner and outer rims to secure an inner tire. Projections from the inner and outer rims are arranged to accommodate the various functions of the combination of the beadlock rings and the inner tire. The projections counterintuitively add weight to the wheel, yet the combination of beadlock rings and an inner tire results in improved stability and safety as well as faster times on the racetrack.

An integral alloy vehicle wheel is provided with a replaceable bead seat protector that protects the bead seat portion of the wheel from tire abrasion and subsequent corrosion. The bead seat protector has a split body to aid in mounting the protector over the outer flanges of the vehicle wheel.

A wheel rim, in particular for a wheel of an agricultural vehicle is disclosed, in which an annular body comprises a central annular portion extending around an axis, two peripheral annular portions for coupling with the beads of a tyre and two intermediate annular portions that connect the two peripheral annular portions to the central annular portion, each intermediate annular portion comprises a tilted wall with an external frustoconical surface that forms an angle with a plane that is perpendicular to the aforesaid axis.
