Description

Technical Field

[0001] The invention belongs to the field of automobile parts manufacturing and relates to an improved FB-I type rim aluminum alloy wheel. Background Art

[0002] The rims of automobile wheels are divided into 5° deep groove rims (5°DC), 15° deep groove rims (15°DC), 5° semi-deep groove rims (5°SDC), 5° bevel bottom rims (5°FB), etc. 5° bevel bottom rims (5°FB) are divided into FB-Ⅰ and FB-Ⅱ. Both FB-Ⅰ and FB-Ⅱ have fixed ends (the wheel rim and the rim body are an integral whole) and detachable ends (the wheel rim is separate). The fixed ends and detachable ends can be used in any combination.

[0003] The materials of automobile wheels include steel, aluminum alloy, magnesium alloy, carbon fiber, etc. Steel and aluminum alloy are the mainstream materials of automobile wheels at present. Lightweight is the general trend, and wheels made of aluminum alloy, magnesium alloy and other materials are in line with this trend and will gradually replace steel wheels.

[0004] FB-Ⅰ rim aluminum alloy wheels are used for special vehicles. The fixed end is made of aluminum alloy, and the detachable end is generally made of steel retaining rings (rims) used for steel wheels. From the front of the wheel, it is obviously a split wheel, which affects the appearance of the wheel; and the wheel can further reduce weight, which not only reduces the production cost of the wheel, but also reduces the weight of the vehicle, thereby reducing the fuel consumption of the vehicle.

[0005] Therefore, it is very necessary to research and develop an improved FB-Ⅰ type rim aluminum alloy wheel so that the wheel can meet the installation and use requirements of special vehicles, while the front of the wheel has an integral wheel structure with a beautiful appearance and reduces the weight of the aluminum alloy wheel, thereby increasing the added value of the aluminum alloy wheel. Summary of the invention

[0006] The object of the present invention is to overcome the shortcomings of the existing 5° bevel bottom rim (5°FB) aluminum alloy wheel and provide an improved FB-I type rim aluminum alloy wheel.

[0007] The technical solution of the present invention is as follows:

[0008] The improved FB-Ⅰ type rim aluminum alloy wheel mainly includes a rim body, a spoke body, an elastic locking ring, an O-shaped rubber sealing ring, and a valve. The rim body and the spoke body are made of aluminum alloy, and the elastic locking ring is made of spring steel. Among them: an inner rim and an inner tire bead seat are arranged on one side of the rim body, and an L-shaped structure similar to a flange is arranged toward the center on the other side. A step groove is processed at the corner of the L-shaped structure. The outer wall surface of the L-shaped structure parallel to the axis of the rim is a cylindrical axial surface, and the inner edge of the center hole at the end of the L-shaped structure is processed into a center hole cone surface; an outer rim and an outer tire bead seat are arranged on the outer wall of the spoke body, and the inner cavity of the spoke body is arranged as a U-shaped structure. The large diameter surface of the U-shaped structure is a cylindrical hole surface, and the small diameter surface is a cylindrical axial surface, and a U-shaped groove is arranged on the small diameter surface of the U-shaped structure. The O-type rubber sealing ring is placed in the step groove of the L-shaped structure of the rim body, the outer wall surface of the L-shaped structure of the rim body matches the large diameter surface of the U-shaped structure of the spoke body, and the outer end surface of the L-shaped structure of the rim body fits with the bottom surface of the U-shaped structure of the spoke body, pressing the O-type rubber sealing ring to play a sealing role; the elastic locking ring is inserted into the U-shaped groove on the small diameter surface of the U-shaped structure of the spoke body, and the conical surface of the elastic locking ring matches the conical surface of the center hole of the L-shaped structure of the rim body to lock the rim body and the spoke body together to form a complete wheel.

[0009] A plurality of air holes are processed at the end of the L-shaped structure of the rim body which is perpendicular to the axis of the rim, and a valve hole is drilled in the middle of the rim body.

[0010] The end surface of the spoke body is processed with air holes of the same number and diameter as those on the rim body, and the flange surface of the spoke body is drilled with a plurality of bolt holes.

[0011] The angle between the conical surface of the center hole of the L-shaped structure of the rim body and the axis of the rim is 45°-60°.

[0012] Compared with the existing 5° bevel bottom rim (5°FB) aluminum alloy wheel, the present invention has the following advantages: after being assembled, the wheel of the present invention is an integral wheel structure when viewed from the front, which is convenient for designing and manufacturing various shapes and has a beautiful appearance; the rim body and the spoke body are both made of aluminum alloy, which effectively reduces the weight of the wheel.
