Description

Technical Field

[0001] This disclosure relates generally to wheels, and in particular to pneumatic covers for wheels, attachment systems for attaching pneumatic covers to wheels, and wheels having such pneumatic covers and attachment systems. Background Technology

[0002] Wheels used in motor vehicles are typically secured to the vehicle by lug nuts. Lug nuts are screwed onto or otherwise tightened to corresponding lug bolts. Lug bolts extend outward from the vehicle and through the wheel disc. Thus, the lug nuts are exposed on the outer side of the wheel, away from the vehicle. Furthermore, the lug bolts typically extend beyond the lug nuts, away from the vehicle. When the vehicle is driven, the lug nuts and lug bolts extending outward from the wheel disc and exposed cause undesirable air resistance (i.e., drag). For example, air resistance caused by lug nuts and lug bolts reduces the vehicle's fuel economy. Therefore, it is desirable to reduce the air resistance caused by lug nuts and lug bolts when the vehicle is driven. Summary of the Invention

[0043] Now for reference Figure 1-4 The diagram illustrates a wheel, generally designated 100, for use in a vehicle. The wheel 100 rotates about a wheel axis 102. The wheel 100 has a disc 104 and a rim 106. The rim 106 is fixed to the disc 104. The general structure of the disc 104 and the rim 106 is known in the prior art. The rim 106 extends axially in a direction parallel to the wheel axis 102. As a non-limiting example, the wheel 100 may be made of steel or aluminum. As a non-limiting example, the wheel 100 may be used in passenger cars, light rail vehicles, or commercial road vehicles.

[0044] Wheel 100 also has an overall designation of 108 and in Figure 1-3 The first pneumatic cover and the overall structure shown are indicated by 110 and are in Figure 1-3The second pneumatic cover is shown in the figure. Preferably, and as shown, the first cover 108 and the second cover 110 are separate components or elements attached or otherwise mounted to a complete wheel, such as wheel 100. The first cover 108 and the second cover 110 are respectively transverse to the wheel axis 102 and centered on the wheel axis 102. In practice, the first cover 108 and the second cover 110 are generally located in planes intersecting the wheel axis 102. As shown, the first cover 108 and the second cover 110 extend radially inward from the rim 106 toward the wheel axis 102 in a direction perpendicular to the wheel axis 102.

[0045] Preferably, the first cover 108 and the second cover 110 are each made of a plastic material. Alternatively, the first cover 108 and / or the second cover 110 may be made of a material different from plastic. As a non-limiting example, the first cover 108 and / or the second cover 110 may be made of a metallic material such as aluminum.

[0046] As shown in the figure, a first cover 108 is mounted on a predetermined outer side of the wheel 100, and a second cover 110 is mounted on a predetermined inner side of the wheel 100. Thus, the first cover 108 and the second cover 110 are located on opposite sides of the wheel 100. Alternatively, the first cover 108 and the second cover 110 may be mounted on the wheel 100 in a manner different from that shown in the figure. As a non-limiting example, the first cover 108 may be mounted on the inner side of the wheel 100 and / or the second cover 110 may be mounted on the outer side of the wheel 100.

[0047] like Figure 1-3 As shown, a first cover 108 extends radially between the wheel axle 102 and the wheel rim 106. As illustrated, the first cover 108 has adjacent first annular portions 112, second annular portions 114, and third annular portions 116. Alternatively, the first cover 108 may have more or fewer annular portions than the first annular portions 112, second annular portions 114, and third annular portions 116, respectively. The first annular portions 112 and third annular portions 116 are generally transverse to the wheel axle 102, and the second annular portion 114 is generally perpendicular to the wheel axle 102. The third annular portion 116 defines an opening 118 in the first cover 108. The opening 118 is preferably a central opening centered on the wheel axle 102. The first annular portions 112, second annular portions 114, and third annular portions 116 will be discussed further.

[0048] Between the third annular portion 116 and the rim 106 is an axial portion 120. As shown, the axial portion 120 extends substantially parallel to the wheel axis 102. Alternatively, the axial portion 120 may not extend substantially parallel to the wheel axis 102. Defined within the axial portion 120 are vents 122 arranged circumferentially around the first cover 108. The vents 122 extend substantially parallel to the wheel axis 102. As shown, the vents 122 are trapezoidal in shape. Alternatively, the vents 122 may not be trapezoidal. As a non-limiting example, the vents 122 may be circular, triangular, or other shapes. As shown, each vent 122 has a corresponding planar tab or flap 124 extending radially from the wheel axis 102. The tab 124 is perpendicular to the axial portion 120 at each corresponding vent 122. The tab 124 breaks radial turbulence and improves airflow through the vent 122. Alternatively, tab 124 may be omitted for one or all of the vents 122. Alternatively, tab 124 may extend in a direction other than that shown in the figure. As a non-limiting example, tab 124 may extend at an acute or obtuse angle relative to the axial portion 120, or tab 124 may be curved or otherwise non-planar.

[0049] As shown, tabs 124 extend radially outward and inward from the axial portion 120. Alternatively, tabs 124 may extend only outward or only inward from the axial portion 120. Alternatively, some tabs of tabs 124 may extend outward from the axial portion 120, while others extend inward from the axial portion 120. Alternatively, different groups of tabs 124 may extend only outward, only inward, and / or both outward and inward from the axial portion 120.

[0050] like Figure 4As shown, the second cover 110 has a first annular portion 126 and a second annular portion 128. Alternatively, the second cover 110 may have more or fewer annular portions than the first annular portion 126 and the second annular portion 128, respectively. The first annular portion 126 and the second annular portion 128 are generally perpendicular to or otherwise transverse to the wheel axis 102. Within the second annular portion 128 are vents 130 arranged circumferentially around the second cover 110. As shown, the vents 130 are arranged to extend substantially transversely to the wheel axis 102 and not radially from the wheel axis 102. As a non-limiting example, the vents 130 may have a helical arrangement around the wheel axis 102. As shown, the vents 130 have generally parallel opposite sides and pass through the second annular portion 128 at an angle to the surface of the second annular portion 128. Alternatively, the vents 130 may differ from those shown in the figure. The first annular portion 126 defines an opening 132 in the second cover 110. Preferably, the opening 132 is a central opening centered on the wheel axis 102.

[0051] Now for reference Figure 5 The diagram illustrates a first attachment system, generally designated 134, for mounting or otherwise securing a first cover 108 to a wheel 100. The first attachment system 134 is preferably used for mounting the first cover 108 to existing wheels without requiring modification of the existing wheels. The first attachment system 134 includes a ring gear or ring 136 and a screw 138, both of which will be referenced to... Figure 6-7A Detailed discussion. Gear 136 is preferably made of a metallic material such as steel or aluminum. Alternatively, gear 136 may be made of a plastic material. Gear 136 has a vertical first portion 140 and a second portion 142. The first portion 140 has a lug opening 144 for a lug bolt, and the second portion 142 has a screw groove, generally indicated by 146, for a screw 138. As shown, the lug opening 144 is circular and the screw groove 146 has an L-shaped shape. Alternatively, the lug opening 144 and / or the screw groove 146 may have shapes different from those shown. Figure 5 The image shows a lug bolt 148 and a lug nut 150 for wheel 100.

[0052] Now for reference Figure 6 and Figure 6AIn the diagram, gear 136 is shown mounted on disc 104. Lug bolt 148 is secured to the vehicle having wheel 100 in a known manner. Lug bolt 148 passes through lug bolt opening 144 in a first portion 140. The first portion 140 is held on lug bolt 148 by lug nut 150, i.e., the first portion 140 is held compressed between disc 104 and lug nut 150. Preferably, the lug bolt opening 144 is sized such that when gear 136 is mounted on disc 104, it is not necessary to rotate or otherwise move gear 136 on disc 104 to assemble lug bolt 148.

[0053] Now for reference Figure 7 and Figure 7A In the diagram, a first cover 108 is shown mounted on a gear 136. The first cover 108 has a support portion 152 extending axially from a first annular portion 112 toward a wheel 104. Within the support portion 152 are an annular groove 154 and a radially extending screw hole, generally indicated by 156. The screw hole 156 is interrupted by the annular groove 154, resulting in a first portion 156A and a second portion 156B on opposite sides of the annular groove 154. A screw 138 travels through a screw groove 146 and lies between the first portion 156A and the second portion 156B of the screw hole 156. Consequently, a second portion 142 of the gear 136 is held in the annular groove 154, and the first cover 108 is mounted on the wheel 100.

[0054] Preferably, the screw 138 is first installed in the screw hole 156 such that the screw 138 spans between the first portion 156A and the second portion 156B. Next, the second portion 142 of the gear is inserted into the annular groove 154 such that the screw 138 enters the first axial portion 146A of the screw groove 146. Finally, the first cover 108 is rotated about the wheel axis 102 such that the screw 138 moves from the first axial portion 146A of the screw groove 146 to the second circumferential portion 146B. The first cover 108 is then installed on the wheel 100. The screw 138 can be tightened once more in the second circumferential portion 146B.

[0055] Figure 6 and Figure 7An external connector, generally designated 158, is also shown between the first cap 108 and the rim 106. The external connector 158 is part of the first attachment system 134. Alternatively, the external connector 158 may be omitted. The rim 106 has an inner lip 160, and the first cap 108 has a beaded portion 162. As shown, the first cap 108 generally extends radially inward from the inner lip 160 and toward the wheel axis 102. More specifically, the first cap 108 extends radially inward from the axial portion 120 toward the wheel axis 102. Alternatively, the second cap 110 may extend in a different manner than shown. The second cap 110 has a greater extension in the radial direction perpendicular to the wheel axis 102 than in the axial direction parallel to the wheel axis 102.

[0056] As a non-limiting example, when the first cover 108 is mounted on the wheel 100, the beaded portion 162 is radially inward toward the wheel axle 102. Simultaneously with this radial inward displacement, the beaded portion 162 is positioned within the inner lip 160. Upon release, the beaded portion 162 moves radially outward from the wheel axle 102 and into the inner lip 160 (i.e., the beaded portion 162 is "clamped" below the inner lip 160).

[0057] Refer again Figure 6 and Figure 7 The geometric relationships between the first annular portion 112, the second annular portion 114, and the third annular portion 116 of the first cover 108 are also shown. Parallel to the wheel axis 102, the first axial dimension 164 of the first annular portion 112 is smaller than the second axial dimension 166 of the third annular portion 116. In the radial direction 168 perpendicular to the wheel axis 102, the first radial dimension 170 of the first annular portion 112 is smaller than the second radial dimension 172 of the third annular portion 116. The third radial dimension 174 of the second annular portion 114 in the radial direction 168 has a value between the first radial dimension 170 and the second radial dimension 172, respectively. The sum of the first radial dimension 170, the second radial dimension 174, and the third radial dimension 172 is greater than either the first axial dimension 164 or the second axial dimension 166, respectively. As a result, the first cover 108 has a greater extension in the radial direction perpendicular to the wheel axis 102 than in the axial direction parallel to the wheel axis 102.

[0058] like Figure 6 and Figure 7As shown, the first annular portion 112 and the third annular portion 116 intersect each other at an angle, meaning they would intersect if the first annular portion 112 and the third annular portion 116 were to extend further. The third annular portion 116 extends radially outward beyond the axial portion 120, thereby defining a “cantilever” protrusion or other protrusion generally indicated by 176. Alternatively, the geometric relationships between the first annular portion 112, the second annular portion 114, and the third annular portion 116 of the first cover 108 may differ from those of the others. Figure 6 and Figure 7 The geometric relationship is shown. Preferably, the first cover 108 extends radially inward from the rim 106 in a direction perpendicular to the wheel axis 102.

[0059] like Figure 6 As shown, the first cover 108 has a "tent-like" shape to clear or otherwise accommodate the lug bolt 148. Since the lug bolt 148 is shortened in a direction parallel to the wheel axis 102 to extend a smaller distance from the wheel disc 104 toward the first cover 108, the first cover 108 can be "flattened" from the tent shape shown by reducing the first axial dimension 164 and the second axial dimension 166, respectively. A recess 178 is defined on the underside of the second annular portion. The recess 178 accommodates the lug bolt 148 (in... Figure 6A (Best shown in the diagram). Preferably, the recess 178 is annular. Alternatively, the recess 178 may be provided only at each lug bolt 148. Alternatively, the recess 178 may be omitted.

[0060] like Figure 6 and Figure 7 As shown, the first annular portion 112, the second annular portion 114, and the third annular portion 116 each have planar segments. Alternatively, one or more of the first annular portion 112, the second annular portion 114, and / or the third annular portion 116 may have curved segments or other non-planar segments.

[0061] As a non-limiting example, the first cover 108 may be integrally manufactured from a plastic material. Alternatively, one or more of the first annular portion 112, the second annular portion 114, the third annular portion 116, and / or the axial portion 120 may be manufactured separately and then assembled or otherwise combined with the remaining portions. When one or more of the first annular portion 112, the second annular portion 114, the third annular portion 116, and / or the axial portion 120 are manufactured separately, one or more of the first annular portion 112, the second annular portion 114, the third annular portion 116, and / or the axial portion 120 may be made of different materials from each other.

[0062] Figure 6 and Figure 7A first cavity or hollow space 179 is shown defined on a predetermined outer side of wheel 100 between vehicle rim 106 and wheel disc 104. A portion of lug bolt 148 and lug nut 150 are located in the first cavity 179. A first cover 108 extends radially inward from vehicle rim 106 toward wheel axle 102 to cover the first cavity 179. As shown, the first cover 108 completely spans or otherwise covers the first cavity 179 (opening 118 is not part of the first cavity 179). Alternatively, the first cover 108 may partially cover the first cavity 179. Furthermore, the first cavity 179 may be defined in a manner different from that shown.

[0063] Now for reference Figure 8-10 The diagram illustrates a second attachment system, generally indicated by 180, for mounting or otherwise securing the second cover 110 to the wheel 100. Preferably, the second cover 110 extends radially inward from the rim 106 in a direction perpendicular to the wheel axis 102.

[0064] The spring ring 182 presses the annular flange portion 184 of the second cover 110 against the annular inner lip 186 of the rim 106. As a non-limiting example, the spring ring 182 may be made of metal or plastic. As shown, the second cover 110 extends radially inward from the inner lip 186 toward the wheel axis 102. Alternatively, the second cover 110 may extend in a manner different from that shown.

[0065] The spring ring 182 has a compression portion generally indicated by 188. As shown, the compression portion 188 has a W-shaped shape. The rim 106 has a through groove or other perforation 190 corresponding to the compression portion 188 of the spring ring 182. Furthermore, the second cover 110 has a gap 192 in the flange portion 184. The gap 192 allows for deformation or other movement of the second cover 110 during installation on the wheel 100 and when the vehicle with the wheel 100 is driven. During installation of the second cover 110 on the wheel 100, the flange portion 184 between the two flange gaps 192 can be displaced to allow the compression portion 188 to enter the through groove 190. Alternatively, a through opening for the compression portion 188 can be provided in the second cover 110.

[0066] When the second cover 110 is installed on the wheel 100, the spring ring 182 presses the flange portion 184 of the second cover 110 against the inner lip 186 of the rim 106. This is achieved by the spring ring 182 having a larger diameter than the rim 106 in its uncompressed state. During the installation of the second cover 110 onto the wheel 100, one or more of the compression portions 188 are compressed and the spring ring 182 is positioned within the flange portion 184. The second cover 110 is then positioned within the rim 106 such that each compression portion 188 is radially aligned with one of the through slots 190. The compression portions 188 are inserted into the through slots 190 (e.g., ...). Figure 9 and Figure 10 (As shown) and the compressed portion 188 is released. Then, the spring ring 182 applies a radially outward force that presses the flange portion 184 against the inner lip portion 186 to secure the second cover 110 to the wheel 100.

[0067] Figure 6 and Figure 7 A second cavity or hollow space 194 is shown defined within a vehicle rim 106 on a predetermined inner side of the wheel 100. A second cover 110 extends radially inward from the vehicle rim 106 toward the wheel axle 102 to cover the second cavity space 194. As shown, the second cover 110 partially covers the second cavity space 194. Alternatively, the second cover 110 may completely cover the second cavity space 194. Furthermore, the second cavity space 194 may be defined in a manner different from that shown.

[0068] Now for reference Figure 11-14A The figure shows a wheel, generally designated 200, according to a second embodiment of the invention. Wheel 200 is a variation of wheel 100. Thus, similar reference numerals for 100 are added to indicate the corresponding parts in the figure, and their detailed description will be omitted.

[0069] The wheel 200 has a first attachment system, generally indicated by 234, which takes the form of an interlocking connection between the wheel 200 and the first cover 208. The wheel disc 204 of the wheel 200 has a groove, generally indicated by 296. As shown, groove 296 is a locking slot. Alternatively, groove 296 may be different from a locking slot. The locking slot 296 is located in the annular hub or wheel mounting portion 298 of the wheel disc 204. The first cover 208 has a flange portion 300 extending from a second annular portion 214 parallel to the wheel axis 202. A screw 302 is partially screwed into the flange portion 300 such that the head of the screw 302 is not flush with or otherwise spaced from the flange portion 300. The screw 302 is then inserted into the locking slot 296, such that the first cover 208 is held on the wheel 200. Alternatively, screw 302 may be a stud formed together with flange portion 300, or screw 302 may be a stud inserted into flange portion 300.

[0070] As a non-limiting example, the first cover 208 can be mounted on the wheel 200 as follows: First, the screw 302 is initially screwed into or otherwise partially inserted into the flange portion 300. Next, the first cover 208 is positioned on the wheel 200 such that the screw 302 first enters the first wide portion 296A of the locking slot 296. Then the first cover 208 is... Figure 13 and Figure 13A The first position in the middle rotates to Figure 14 and 14A The screw 302 is positioned such that it enters the second narrow portion 296B of the lock hole groove 296. Preferably, the second narrow portion 296B is sized to provide an interference fit between the second narrow portion 296B and the screw 302 to secure the first cover 208 to the wheel 200. The screw 302 can then be tightened against the wheel disc 204 to further secure the first cover 208 to the wheel 200.

[0071] Now for reference Figure 15 and Figure 16 The figure shows a wheel, generally designated 400, according to a third embodiment of the invention. Wheel 400 is a variation of wheel 100. Thus, a similar reference numeral 300 is added to indicate the corresponding part in the figure, and its detailed description will be omitted.
