Description

[0001] This divisional application is a divisional application based on the Chinese patent application with application number 201780050164.7, application date August 16, 2017, and invention name "Vehicle wheel disc, vehicle wheel including such a wheel disc, and method for producing such a wheel disc and vehicle wheel". The Chinese patent application is the Chinese national phase of the international application with international application number PCT / US2017 / 047081. Technical Field

[0002] The present invention relates generally to vehicle wheel discs and vehicle wheels and in particular to an improved wheel disc, a vehicle wheel including such a wheel disc and a method for producing such a wheel disc and vehicle wheel. Background Art

[0003] Wheels for motor vehicles may be made of lightweight metals to reduce the weight of the wheel. For example, a vehicle wheel may be made of aluminum or its alloys. The weight of such a wheel may be further reduced by removing mass (e.g., material) from the wheel. However, removing mass from the wheel also reduces the stiffness and hardness of the wheel. When the stiffness and hardness of the wheel are reduced, the performance of the wheel may be affected. Therefore, it is desirable to remove mass from the wheel without reducing the stiffness and hardness. Summary of the invention

[0031] Referring now to the accompanying drawings, Figure 1-7 A first embodiment of a vehicle wheel is shown, generally indicated at 100. The vehicle wheel 100 includes an "inner" wheel disc or front portion, generally indicated at 102, and a "full" wheel rim, generally indicated at 104. While the present invention is shown and described in conjunction with the particular vehicle wheel configuration disclosed herein, it should be understood that the present invention may be used with other types of vehicle wheel configurations.

[0032] As shown, the wheel disc 102 and the wheel rim 104 are integrally or unitarily manufactured - for example, as a single casting. Alternatively, the wheel disc 102 and the wheel rim 104 can be produced separately - for example, as separate castings and / or non-castings - and then joined together by suitable means to produce a "fabricated" vehicle wheel 100. Preferably, the vehicle wheel 100 is made of a single casting, and the single casting is made of aluminum or an alloy thereof. Alternatively, the vehicle wheel 100 can be formed of any suitable material. As a non-limiting example, the vehicle wheel 100 (i.e., one or both of the wheel disc 102 and the wheel rim 104) can be integrally (i.e., as a single unit) formed or formed as separate components and fixed together by suitable means, and can be formed of similar materials and / or different materials, including but not limited to aluminum, magnesium, titanium or alloys thereof, steel, carbon fiber and / or composite materials.

[0033] The wheel disc 102 is shown defining a wheel axis X ( Figure 4). The wheel disc 102 includes a generally centrally located wheel mounting portion or hub portion 106 and a plurality of spokes 108 extending outwardly from the wheel mounting portion 106. The wheel mounting portion 106 has a wheel mounting portion height 110. The wheel disc 102 accordingly has opposing outer and inner sides 112 and 114.

[0034] In the illustrated embodiment, the wheel disc 102 includes five such spokes 108, which are shown as being integrally formed with the wheel mounting portion 106 and the wheel rim 104. Alternatively, if desired, the number of spokes 108 may be different than that shown. For example, the vehicle wheel 100 may include fewer than five spokes 108 or more than five spokes 108. Alternatively, the spokes 108 may be formed separately and secured to the wheel rim 104 and the wheel mounting portion 106 by suitable means, and the wheel rim 104 may be integrally formed with each other but formed separately from the wheel mounting portion 106 and attached thereto by suitable means.

[0035] In the illustrated embodiment, the wheel mounting portion 106 is provided with a centrally located pilot aperture or hub bore 116. The pilot aperture 116 extends along the wheel axis X. Circumferentially spaced (in the wheel mounting portion 106) around the pilot aperture 116 are a plurality of lug bolt receiving apertures 118. In the illustrated embodiment, the wheel mounting portion 106 includes five lug bolt receiving apertures 118, which are preferably disposed in the wheel mounting portion 106 radially "aligned" with a corresponding one of the spokes 108. Alternatively, the number and / or location of the lug bolt receiving apertures 118 may be different than that illustrated, if desired. The lug bolt receiving apertures 118 receive lug bolts (not shown) for securing the vehicle wheel 100 to an axle (not shown) of an associated vehicle via nuts (not shown).

[0036] The "jet tail" or "raised T" rim joint (usually indicated at 120 and on Figure 2A 104) to connect, secure or otherwise join the spokes 108 to the wheel rim 104. As such, the rim engaging portion 120 is located at the end of the spoke 108 opposite the wheel mounting portion 106. As non-limiting examples, the "jet tail" or "raised T" rim engaging portion 120 provides additional rigidity to the associated spoke 108 and provides a connection between the spoke 108 and the wheel rim 104. The rim engaging portion 120 has first, second and third portions or tails 122, 124 and 126, respectively.

[0037] The first portion 122 extends in an axial direction 128, wherein the axial direction 128 is parallel to the wheel axis X. As shown, the first portion 122 extends in the axial direction 128 from the spoke 108 and toward an outboard edge 130 of the wheel rim 104. The outboard edge 130 is the edge of the wheel rim 104 that is located on the outside relative to the vehicle, to which the vehicle wheel 100 is secured. Alternatively, the rim engaging portion 120 can be "inverted" from the illustrated configuration - for example, the first portion 122 can extend toward an inboard edge 152 instead of the outboard edge 130. The inboard edge 152 is the edge of the wheel rim 104 that is located on the inside relative to the vehicle, to which the vehicle wheel 100 is secured. Furthermore, the inboard edge 152 is opposite the outboard edge 130 on the wheel rim 104. As shown, the first portion 122 is symmetrical about a spoke centerline 132 of the spokes 108, wherein the spoke centerline 132 extends radially from the wheel mounting portion 106 to the wheel rim 104. Alternatively, the first portion 122 may not be symmetrical about the spoke centerline 132.

[0038] The first portion 122 has a first thickness 134 at the end closest to the wheel mounting portion 106 and a second thickness 136 at the wheel rim 104. The first thickness 134 and the second thickness 136 are measured transversely to the spoke centerline 132. As shown, the second thickness 136 is less than the first thickness 134. Alternatively, the second thickness 136 may be greater than the first thickness 134, or the first thickness 134 and the second thickness 136 may be equal, respectively. Preferably, for a 19×4.5 one-piece cast aluminum wheel, the first thickness 134 is included in the range of 10 mm to 30 mm, and the second thickness 136 is included in the range of 5 mm to 50 mm. More preferably, the first thickness 134 is included in the range of 10 mm to 30 mm, and the second thickness 136 is included in the range of 5 mm to 30 mm. Each first portion 122 may have the same first thickness 134 and second thickness 136, respectively. Alternatively, one or more of the first portions 122 may have different first thicknesses 134 or second thicknesses 136, respectively. Furthermore, all ranges used herein are for the sizes and types of vehicle wheels described above, and thus for other sizes and / or types of vehicle wheels, the "range" may differ from that described.

[0039] The first portion 122 also has a curved surface 138 that is located between the first thickness 134 and the second thickness 136, respectively. The curved surface 138 extends generally in the axial direction 128 and has a first radius 140. The first radius 140 can be constant or variable.

As shown, the second portion 124 and the third portion 126 are respectively preferably symmetrical to each other across the spoke centerline 132. In this way. The discussion of one of the respective second portion 124 or third portion 126 also applies to the other of the respective second portion 124 or third portion 126. Alternatively, the second portion 124 and the third portion 126 may be respectively asymmetrical to each other across the spoke centerline 132.

[0042] As shown, the second portion 124 and the third portion 126 respectively extend from the spoke 108 to the wheel rim 104 in a circumferential direction 144, wherein the circumferential direction 144 follows the circumference or perimeter of a circle about the wheel axis X. The circle lies in a plane that is preferably perpendicular to the wheel axis X, and the wheel axis X is located at the center of the circle. Preferably, the second portion 124 and the third portion 126 respectively are curved and also extend from the spoke 108 to the wheel rim 104 in an axial direction 128 - that is, the second portion 124 and the third portion 126 respectively preferably extend in both the circumferential direction 144 and the axial direction 128. Alternatively, the second portion 124 and the third portion 126 respectively extend from the spoke 108 to the wheel rim 104 only in the circumferential direction 144.

[0043] The second portion 124 and the third portion 126 respectively have a third thickness 146. As shown, the third thickness 146 is preferably less than both the corresponding first thickness 134 and the second thickness 136. Alternatively, the third thickness 146 may be equal to the corresponding first thickness 134 or the second thickness 136, greater than one or both of the corresponding first thickness 134 or the second thickness 136, or greater than one of the corresponding first thickness 134 and the second thickness 136 and less than the other of the first thickness 134 and the second thickness 136. Preferably, the third thickness 146 is included in the range of 5 mm to 30 mm. More preferably, the third thickness 146 is included in the range of 5 mm to 15 mm. Each of the second portion 124 and the third portion 126 may respectively have the same third thickness 146. Alternatively, one or more of the second portion 124 or the third portion 126 may respectively have different third thicknesses 146.

[0044] The second portion 124 and the third portion 126, respectively, preferably have a curved edge 148 between the spoke 108 and the wheel rim 104. The curved edge 148 has a second radius 150. The second radius 150 can be constant or variable. Preferably, the second radius 150 is included in the range of 10 mm to 100 mm. More preferably, the second radius 150 is included in the range of 10 mm to 60 mm. Each of the second portion 124 and the third portion 126, respectively, can have the same second radius 150. Alternatively, one or more of the second portion 124 or the third portion 126, respectively, can have different second radii 150. Alternatively, the second portion 124 and the third portion 126, respectively, can have a flat or other shaped surface between the spoke 108 and the wheel rim 104.

[0045] In addition, the second portion 124 and the third portion 126 extend from the spoke 108 toward the inner edge 152 of the wheel rim 104, respectively. The second portion 124 and the third portion 126 are respectively bent toward the inner edge 152 at a third radius 154. Preferably, the third radius 154 is included in the range of 10 mm to 50 mm. More preferably, the third radius 154 is included in the range of 10 mm to 30 mm. Each of the second portion 124 and the third portion 126 can respectively have the same third radius 154. Alternatively, one or more of the second portion 124 or the third portion 126 can respectively have different third radii 154. Alternatively, the second portion 124 and the second portion 126 can respectively extend toward the inner edge 152 with a flat surface or other shaped surfaces.

[0046] The second portion 124 and the third portion 126 respectively have a joint length 156 extending in the circumferential direction 144 at the wheel rim 104. The joint length 156 is preferably greater than the third thickness 146. As shown, the joint length 156 is also preferably greater than the joint height 142. Alternatively, the joint length 156 may be less than or equal to the joint height 142. Preferably, the joint length 156 is included in the range of 5 mm to 50 mm. More preferably, the joint length 156 is included in the range of 5 mm to 35 mm. Each of the second portion 124 and the third portion 126 may respectively have the same joint length 156. Alternatively, one or more of the second portion 124 or the third portion 126 may respectively have different joint lengths 156.

[0047] As shown, the angle 158 between the first portion 122 and the second portion 124 and the third portion 126 at the wheel rim 104 is preferably substantially 90 degrees (shown between the joint height 142 and the joint length 156). Alternatively, the angle 158 may not be 90 degrees. For example, the angle 158 may be greater than 90 degrees. As a non-limiting example, the angle 158 may be 120 degrees, so that the first, second and third portions 122, 124 and 126 are equally spaced circumferentially around the spoke 108.

[0048] As shown, the first portion 122 is a single member. Alternatively, the first portion 122 can be two members, so that the rim engaging portion 120 has a generally "X" shape, wherein the two first portions 122 extend toward the outer edge 130, and the second portion 124 and the third portion 126 extend toward the inner edge 152, respectively. Preferably, the two first portions 122 and the second portion 124 and the third portion 126, respectively, will be evenly spaced apart at 90 degrees. Alternatively, the two first portions 122 and the second portion 124 and the third portion 126, respectively, can be spaced apart at angles other than 90 degrees.

[0049] The bridge joint 160 spans between or otherwise connects adjacent spokes of the plurality of spokes 108. As a non-limiting example, the bridge joint 160 provides additional rigidity between adjacent pairs of spokes 108 and provides additional rigidity to the vehicle wheel 100. The bridge joint 160 defines a first opening 162 and a second opening 164 in the wheel disc 102, respectively.

[0050] The bridge joint 160 may have a constant or varying thickness in the axial direction 128. Some bridge joints 160 may have a constant thickness while other bridge joints 160 have a varying thickness. The thickness of the bridge joint 160 may vary between bridge joints 160 or within a single bridge joint 160. As a non-limiting example, the bridge joint 160 may be manufactured with a constant thickness and then have material or structure machined away to vary the thickness.

[0051] Alternatively, if Figure 7 As shown, the bridging joint 160 may be omitted from the wheel disc 102. When the bridging joint 160 is omitted, only a single larger second opening 164 is provided in the wheel disc 102 between adjacent pairs of spokes 108.

[0052] A plurality of hub recesses (indicated at 166 and in Figure 3A 106 ). Preferably, the hub recess 166 is both “deep” and open. As a non-limiting example, the hub recess 166 reduces the weight of the vehicle wheel 100 .

[0053] The hub recesses 166 are interspaced between the lug bolt receiving holes 118. As shown, there are five hub recesses 166. Alternatively, the wheel disc 102 may have fewer than or more than five hub recesses 166. As non-limiting examples, a hub recess 166 may not be disposed between each pair of lug bolt receiving holes 118, or more than one hub recess 166 may be disposed between pairs of lug bolt receiving holes 118. As shown, the hub recesses 166 are defined in the wheel mounting portion 106 by the lug bolt receiving holes 118 and corresponding coaxial inner and outer rings 168, 170 in the wheel mounting portion 106.

[0054] The hub recess 166 has a hub recess depth 172 (eg Figure 4 1). The wheel hub recess depth 172 is preferably less than the wheel mounting portion height 110. Thus, the wheel hub recess 166 preferably has a radially extending bottom wall 174. The bottom wall 174 defines the wheel hub recess 166 so that they are not through openings in the axial direction 128. The wheel hub recess depth 172 reaches the bottom wall 174.

[0055] As shown, the hub recess depth 172 is preferably less than the wheel mounting portion height 110 by the inner ring height 176 of the inner ring 168. Alternatively, the hub recess depth 172 may be less than the wheel mounting portion height 110 by a height other than the inner ring height 176. Preferably, the hub recess depth 172 is included in the range of 10 mm to 60 mm. More preferably, the hub recess depth 172 is included in the range of 10 mm to 45 mm. Each hub recess 166 may have the same hub recess depth 172. Alternatively, one or more hub recesses 166 may have different hub recess depths 172. Alternatively, the hub recess 166 may be omitted from the wheel disc 102.

[0056] The hub recess 166 preferably has a hub recess opening 178 in a side wall 180 thereof, such as Figure 3A 1. The sidewall 180 extends in the axial direction 128 and is a radially outward extension of the wheel mounting portion 106. The outer ring 170 aligns with or otherwise "caps" the sidewall 180 on the inner side 114. The hub recess opening 178 has a hub recess opening width 182 and a height 184. Each hub recess opening 178 can have the same hub recess opening width 182 and hub recess height 184. Alternatively, one or more hub recess openings 178 can have different hub recess widths 182 or hub recess heights 184. Alternatively, the hub recess opening 178 can be omitted from the wheel disc 102 if desired.

[0057] Inner ring 168 has a predetermined thickness 186. Preferably, inner ring thickness 186 is included in the range of 5 mm to 50 mm. Outer ring 170 has a thickness 188. Preferably, outer ring thickness 188 is included in the range of 5 mm to 10 mm. As shown, inner ring thickness 186 is greater than outer ring thickness 188. Alternatively, inner ring thickness 186 may be less than or equal to outer ring thickness 188. Inner ring 168 and outer ring 170 are respectively substantially perpendicular to bottom wall 174 at hub recess 166.

[0058] like Figure 3 As shown at 190 in FIG. 1 , the outer ring 170 is preferably tangential to the lug bolt receiving holes 118 and spans between the lug bolt receiving holes 118. Preferably, as shown in FIG. Figure 3AAs shown, the distance 192 from the radially inner surface of the inner ring 168 to the radially outer surface of the outer ring 170 is included in the range of 10 mm to 50 mm. More preferably, the distance 192 from the radially inner surface of the inner ring 168 to the radially outer surface of the outer ring 170 is included in the range of 10 mm to 35 mm. The outer ring 170 can be omitted from the wheel disc 102. As a non-limiting example, the weight of the vehicle wheel 100 is reduced by omitting the outer ring 170. When the outer ring 170 is omitted, the spokes 108 are connected by the bridge joint 160, and the hub recess 166 is defined in the wheel mounting portion 106 by the lug bolt receiving holes 118 and the outer ring 170.

[0059] Spoke notches or recesses (usually indicated by 194 and Figure 2B 108) preferably extends from the outer side 112 into the spokes 108. Alternatively, the spoke recesses 194 may extend from the inner side 114 into the spokes 108. As a non-limiting example, the spoke recesses 194 reduce the weight of the vehicle wheel 100 and provide additional stiffness to the spokes 108. Furthermore, while only a single spoke recess 194 is shown as being provided in each spoke 108, one or more spokes 108 may be provided with more than one spoke recess 194 if desired.

As shown, the first partial opening 438 is centered on the center line 332 along the circumferential direction 344. Alternatively, the first partial opening 438 may not be centered on the center line 332 along the circumferential direction 344. Alternatively, the first partial opening 438 may be omitted.

[0080] In the circumferential direction 344, the first fork 432 has a first thickness 440 and the second fork 434 has a second thickness 442. Preferably, the first thickness 440 and the second thickness 442 are respectively equal. Alternatively, the first thickness 440 may be greater than or less than the second thickness 442.

Alternatively, one or both of the first thickness 440 and the second thickness 442 may vary between the spokes 308 and the wheel rim 304, respectively. For example, the first thickness 440 and / or the second thickness 442 may increase or decrease between the spokes 308 and the wheel rim 304, respectively.

[0086] In addition, the second portion 324 and the third portion 326 respectively diverge from each other from the spoke centerline 332. The second portion 324 and the third portion 326 respectively each have a distance from the spoke centerline 332 to the point farthest from the spoke centerline 332 (for example, the farthest point of the third portion 326 is the rightmost point of the fourth fork 450, see Fig. 8A 4. The divergence distance 452 is preferably greater than the first height 444 and the second height 446, respectively.
