Description

TITLE
WHEEL RIM AND METHOD FOR PRODUCING SAME
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application Serial No. 60/070,023, filed December 30, 1997.
BACKGROUND OF THE INVENTION This invention relates in general to vehicle wheels and in particular to an improved wheel rim and method for producing the same.
A typical sequence of steps which can be used to produce a wheel rim for a vehicle wheel is disclosed in U.S. Patent No. 4,185,370 to Evans. As shown in this patent, the method includes the steps of: (a) providing a flat sheet of suitable material, such as steel or aluminum; (b) forming the sheet into a cylindrical hoop or band; (c) securing the ends of the hoop together by a butt welding process; (d) flaring the lateral edges of the hoop radially outwardly to produce a rim preform having flanges suitable for positioning on a roll forming machine: (e) subjecting the rim preform to a series of roll forming operations to produce a wheel rim having a predetermined shape; and (f) expanding the wheel rim to produce a finished wheel rim having a predetermined circumference.
SUMMARY OF THE INVENTION This invention relates to an improved wheel rim and method for producing the same. The wheel rim of the present invention is produced using a blank which has been formed into a hoop and having the opposed ends thereof joined together using a friction stir welding process. The method for producing the wheel rim of the present invention includes the steps of: (a) providing a flat blank of material having a pair of opposed ends; (b) providing a chamfer in the opposed ends of the flat blank; (c) positioning the opposed ends of the blank adjacent one another to form a generally cylindrical hoop; (d) providing a pair of flats on the hoop in the region where the opposed ends meet; (e) joining the flattened opposed ends of the hoop together using a friction stir welding process; and (f) subjecting the hoop to one or more metal forming processes in order to produce a desired wheel rim. The use of the friction stir welding process to join the ends of the hoop together is more controllable, simpler, and uses less energy than the .known butt welding process typically used to produce a prior art wheel rim.
Other advantages of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiments, when read in light of the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, there is illustrated in Fig. 1 a block diagram showing a first sequence of steps for producing a vehicle wheel 100, such as shown in Fig. 11, and which incorporates a first embodiment of a wheel rim, indicated generally at 58, constructed in accordance with this invention. As shown in this embodiment, the vehicle wheel 100 is a mil face fabricated type of vehicle wheel which is typically found on a passenger car or light truck. Initially in step 10, a flat sheet or blank 30 of suitable material, such as for example, steel, aluminum or alloys thereof, shown in Fig. 2 and having opposed ends 30A and 3 OB, is formed into a generally cylindrical hoop or band 32 shown in Fig. 3. Next, in step 12, the hoop 32 is welded using a friction stir welding process. To accomplish this, the hoop 32 is supported on a fixture (not shown) and a rotating tool 34 of a friction stir weld tool is used to form a weld 36 which is effective to secure the ends 30A and 3 OB of the hoop 32 together and thereby produce a welded hoop 38, partially shown in Fig. 4. Such a friction stir welding process is described in U.S. Patent No. 5,460,317 to Thomas et al., the disclosure of which is incorporated herein by reference. Preferably, in order to provide complete penetration of the friction stir weld 36, a groove or chamfer 30C and 30D is provided in a lower portion of the respective ends 30A and 3 OB of the flat sheet of material 30 so that when the ends 30A and 30B are placed adjacent one another, the chamfers 30C and 30D cooperate to form a generally inverted V- shaped annular groove 30E in the lower portion thereof, shown in Fig. 3 A. Following this, the hoop 38 is expanded in step 14 to produce a substantially cylindrical hoop 40 shown in Fig. 5. In the illustrated embodiment, the hoop 40 extends a predetermined axial length X, includes an inner surface 40A which defines an inner diameter Dl and an outer surface 40B which defines an outer diameter D2, and includes a substantially uniform first thickness T throughout its entire axial length X. Alternatively, the hoop 40 can be other than illustrated if desired. For example, the hoop 40 can be of varying thicknesses as disclosed in U.S. Patent No. 5,832,609 to Jansen, the disclosure of which is incorporated herein by reference. Next, in step 16, an end of the hoop 40 is flared upwardly as to produce a wheel rim preform 42 shown in Fig. 6. Following this, in steps 18, 20, and 22, the wheel rim preform 42 is subjected to a series of metal forming operations, as shown in Figs. 7, 8, and 9, to progressively produce variable thickness wheel rims 44, 46, and 48, respectively. Preferably, the metal forming operations of steps 18, 20, and 22 include subjecting the wheel rim preform 42 to a series of roll forming operations since tighter tolerances can be maintained in the wheel rim 48. Alternatively, other metal forming operations can be used in one or more of the steps 18, 20, and 22 to progressively produce the wheel rim 48. For example, the wheel rim preform 42 can be subjected to foiward or reverse flow spinning operations, pressing operations, or any suitable combinations of roll forming, flow spinning, and pressing operations which are operative to cause deformation, reshaping, and/or thinning of the metal to produce a variable thickness wheel rim having 48 having a desired profile. Also, as will be discussed below, the welded hoop 40 can be used to produce a generally uniform or constant thickness wheel rim, indicated generally at 158 in Fig. 17, which is illustrated as being joined to a wheel disc 170 to produce a vehicle wheel 200, which is illustrated as being a "ledge welded" vehicle wheel which is typically used on a medium or heavy duty truck.
As shown in Fig. 9, the wheel rim 48 includes an inboard tire bead seat retaining flange 50, an inboard tire bead seat 52, a generally axially extending well 54, and an outboard tire bead seat 56. Next, in step 24, the wheel rim 48 is expanded to produce a finished wheel rim 58. The finished wheel rim 58 defines a finished wheel rim axial length XI . In the illustrated embodiment, the axial length XI of the finished wheel rim 58 is greater than the axial length X of the hoop 40. Alternatively, the axial length X of the hoop 40 and the axial length XI of the finished wheel rim 58 can be other than illustrated. For example, depending upon the particular structures of the rim blank 30 and the wheel rim 58, the axial length XI of the finished wheel rim 58 can be equal to or less than the axial length X of the hoop 40. In step 26, the finished wheel rim 58 is secured to a preformed full face wheel disc 60 by a weld 80 to produce the finished full face fabricated vehicle wheel 100, shown in Fig. 11. As shown therein, the wheel disc 60 includes a central mounting portion 62, an intermediate bowl-shaped portion 64, and an outer annular portion 66 which defines an outboard tire bead seat retaining flange 68 of the full face fabricated vehicle wheel 100. The wheel disc 60 can be formed from a suitable material, such as for example, steel, aluminum or alloys thereof.
Referring now to Fig. 12, there is illustrated a block diagram showing a second sequence of steps for producing a vehicle wheel 200, such as shown in Fig. 17, and which incorporates a second embodiment of a wheel rim, indicated generally at 158, constructed in accordance with this invention. As shown in this embodiment, the vehicle wheel 200 is a fabricated truck type of vehicle wheel. Initially in step 110, opposed ends 132 and 134 of a flat sheet or blank 130 of suitable material, such as for example, steel, aluminum or alloys thereof, are provided with chamfers 132A and 134A, respectively, as shown in Fig. 13. Next, in step 112, the opposed ends 132 and 134 are provided with "flattened" portions 136 and 138, respectively, shown in Fig. 14. As used herein, the term flattened portion means a portion of the blank 130 which is oriented at a predetermined angle relative to the remainder of the generally planar surface of the blank 130. In step 1 14, the opposed ends 132 and 134 are positioned adjacent one another so as to form the blank 130 into a generally cylindrical hoop or band 142 shown in Fig. 15. Next, in step 1 16, the hoop 142 is welded using a friction stir welding process. To accomplish this, the hoop 142 is supported on a fixture (not shown) and a rotating tool 144 of a friction stir weld tool is used to form a weld 146 which is effective to secure the ends 132 and 134 of the hoop 142 together and thereby produce a welded hoop 148, partially shown in Fig. 16. As shown in Fig. 16, the chamfered ends 132 A and 134A cooperate to define a generally inverted V-shaped opening or recess in lower portion of the hoop 142 which is effective to provide complete penetration of the friction stir weld 146. Also, as shown in Fig. 16, the flattened portions 136 and 138 of the hoop 142 extend a predetermined distance X2 and X3, respectively, relative to ends 132 and 134 thereof. In the illustrated embodiment, the distance X2 and X3 are generally equal to one another. However, the distances X2 and X3 can be other than illustrated if desired.
Following this, the hoop 142 is expanded in step 1 18, flared in step 120, subjected to a series of metal forming operations in steps 122, 124, and 126, and expanded in step 128 to produce the generally constant thickness truck style wheel rim 158, shown in Fig. 17. Next, in step 130, the finished wheel rim 158 is secured to a preformed wheel disc 170 by a weld 180 to produce the finished ledge welded truck style vehicle wheel 200, shown in Fig. 17. As shown therein, the wheel rim 158 includes an inboard tire bead seat retaining flange 160, an inboard tire bead seat 162, a well 164, an outboard tire bead seat 166, and an outboard tire bead seat retaining flange 168. The wheel disc 170 includes a central mounting portion 172 and an outer annular portion 174. The wheel disc 170 can be formed from a suitable material, such as for example, steel, aluminum or alloys thereof. While the present invention has been illustrated and described as forming a variable thickness wheel rim 58 for use in a full face fabricated vehicle wheel 100, and a constant thickness wheel rim 158 for use in a ledge welded vehicle wheel 200, the present invention can be practiced to form an associated wheel rim for use in other types of wheels. For example, as shown in Fig. 18, the present invention can be practiced to produce a wheel rim 210, which is secured to a preformed wheel disc 212 to produce a well-attached fabricated vehicle wheel 214. Also, as shown in Fig. 19, the present invention can be practiced to produce a wheel rim 220, which is secured to a preformed wheel disc 224 to produce a bead seat attached fabricated vehicle wheel 224. In addition, as shown in Fig. 20, the present invention can be practiced to produce a partial wheel rim 230, which is secured to a cast full face wheel disc 232 to produce a full face modular vehicle wheel 234.
One advantage of the present invention is that the friction stir welding process is more controllable than the prior art current butt welding process that is used to form the prior art welded hoop. Also, using the friction stir welding to weld the ends of the hoop together in accordance with the present invention is simpler and uses less energy than the .known prior art butt welding process typically used to weld the ends together of the prior art welded hoop used in making the prior art wheel rim.
In accordance with the provisions of the patents statues, the principle and mode of operation of this invention have been described and illustrated in its preferred embodiments. However, it must be understood that the invention may be practiced otherwise than as specifically explained and illustrated without departing from the scope or spirit of the attached claims.
