Definitions
- Vehicle wheels typically have an aperture or hole for receiving a valve stem to allow inflation and deflation of a tire mounted to the wheel.
- Original equipment manufacturers offer a wide range of wheels across vehicle model lines, including different materials.
- the use of different materials for various wheel designs has resulted in a proliferation of valve hole parameters. More specifically, wheels using one material, e.g., aluminum, may require a greater thickness in support areas of a wheel, compared with wheels using an inherently stronger material, e.g., steel. Accordingly, valve holes may have different dimensions or other configurations.
- valve stem assemblies have become more complex in recent years, e.g., by incorporating electronics such as tire pressure monitoring systems, manufacturers have sought to reduce the number of different configurations to allow reducing costs through greater economies of scale.
- some types of tire pressure monitoring systems generally require a consistent thickness of an aperture at an interface where the valve stem is secured to the valve hole. Accordingly, it would be advantageous to have a same thickness across the different wheel designs to allow use of a single valve stem design in each of the different designs.
- the different valve hole configurations of the different wheels have contributed to greater complexity and increased costs as a result of the different interfaces required for the different wheel designs.
- Various exemplary illustrations described herein are directed to a method of making a wheel, including stamping a wheel blank, and forming a lip extending about a periphery of an aperture defined by the wheel blank.
- the aperture may be configured to receive a valve stem.
- the method may further include refining the lip about the periphery of the aperture.
- the lip may define an axial thickness greater than a baseline thickness of the wheel blank adjacent the aperture.
- a method further includes providing a second wheel blank having a second aperture configured to receive a valve stem.
- the second aperture may define an axial thickness greater than the baseline thickness of the first wheel blank, while the lip axial thickness of the first wheel blank is substantially equal to axial thickness of the second aperture.

In some exemplary approaches, a method further includes providing a second wheel blank having a second aperture configured to receive a valve stem.

Description
- Vehicle wheels typically have an aperture or hole for receiving a valve stem to allow inflation and deflation of a tire mounted to the wheel. Original equipment manufacturers offer a wide range of wheels across vehicle model lines, including different materials. The use of different materials for various wheel designs has resulted in a proliferation of valve hole parameters. More specifically, wheels using one material, e.g., aluminum, may require a greater thickness in support areas of a wheel, compared with wheels using an inherently stronger material, e.g., steel. Accordingly, valve holes may have different dimensions or other configurations.
- The different valve hole configurations have resulted in a number of different interfaces for the valve stem assemblies. As valve stem assemblies have become more complex in recent years, e.g., by incorporating electronics such as tire pressure monitoring systems, manufacturers have sought to reduce the number of different configurations to allow reducing costs through greater economies of scale. For example, some types of tire pressure monitoring systems generally require a consistent thickness of an aperture at an interface where the valve stem is secured to the valve hole. Accordingly, it would be advantageous to have a same thickness across the different wheel designs to allow use of a single valve stem design in each of the different designs. The different valve hole configurations of the different wheels, however, have contributed to greater complexity and increased costs as a result of the different interfaces required for the different wheel designs.
- Accordingly, there is a need for a vehicle wheel system and associated method of making the same that addresses the above disadvantages.
- Various exemplary illustrations described herein are directed to a method of making a wheel, including stamping a wheel blank, and forming a lip extending about a periphery of an aperture defined by the wheel blank. The aperture may be configured to receive a valve stem. The method may further include refining the lip about the periphery of the aperture. The lip may define an axial thickness greater than a baseline thickness of the wheel blank adjacent the aperture.
- In some exemplary approaches, a method further includes providing a second wheel blank having a second aperture configured to receive a valve stem. The second aperture may define an axial thickness greater than the baseline thickness of the first wheel blank, while the lip axial thickness of the first wheel blank is substantially equal to axial thickness of the second aperture.

FIGS. 1A and 1B , anexemplary wheel 100 is illustrated.Wheel 100 may generally include ahub portion 102 centrally disposed with respect to arim portion 104, which extends about a perimeter of thehub portion 102. Thehub portion 102 may define one or more apertures or holes (not shown) for selective securement of thewheel 100 to a vehicle, e.g., to a vehicle hub using lugnuts or the like. Therim portion 104 may support the mounting of a tire. Theexemplary wheel 100 illustrated may be formed of a stamped steel material. In one exemplary illustration, thehub portion 102 andrim portion 104 are each stamped from sheet steel, and are subsequently joined together, e.g., via welding. - The
rim portion 104 generally defines an aperture orvalve hole 106. As will be described further below,valve hole 106 may generally receive a valve stem (not shown inFIGS. 1A and 1B ) to allow selective inflation and deflation of a tire associated withwheel 100. For example, therim portion 104 may receive a tire mounted via a bead (not shown) such that the tire is mounted to therim portion 104 in a tubeless arrangement. The aperture orvalve hole 106 is defined in part by alip 108. Thelip 108, as will be described further below, may generally be formed such that it extends away from a baseline portion or therim portion 104. In the example shown inFIG. 1A , thelip 108 extends toward an exterior side of therim portion 104, although as will be explained below thelip 108 may alternatively extend into an interior portion of therim portion 104. - The
lip 108 may generally include a refined or smooth surface along at least a portion of the perimeter of thevalve hole 106. For example, thelip 108 generally defines anoffset surface 110 which is spaced away from abaseline surface 112. Theoffset surface 110 may be refined or smoothed, as will be described further below, such that thesurface 110 is generally free of burrs or edges that might otherwise damage a valve stem received within theaperture 106 and/orlip 108. In one exemplary illustration, a refining operation such as a coining process may generally work upon theoffset surface 110 and/or thebackside surface 112 of thewheel 100. Theoffset surface 110 andbaseline surface 112 generally define an axial thickness D1 corresponding to a thickness of thelip 108. The axial thickness D1 may be larger with respect to a baseline thickness D2 of therim portion 104 of thewheel 100. Thickness D2 may be generally equivalent to a sheetmetal thickness of a stamped sheet used in forming thewheel 100 and/orrim portion 104 thereof. - Turning now to
FIGS. 2A , 2B, and 2C, anotherexemplary wheel 200 is illustrated.Wheel 200 may be formed of a different material thanwheel 100. In one exemplary illustration, thewheel 200 is formed of a cast aluminum material. As will be described further below, the material used to form thewheel 200 may in some examples have one or more material properties, e.g., a lower strength than a material used to formwheel 100, that necessitates an overallthicker wheel 200. More specifically,wheel 200 may include ahub portion 202 and arim portion 204. Therim portion 204 may generally define a baseline thickness D4. The baseline thickness D4 may be greater than the baseline thickness D2 ofwheel 100. For example, as noted above, a cast construction and or aluminum material may generally require a greater thicknessadjacent valve hole 206 compared with the baseline thickness D2 ofwheel 100adjacent valve hole 106. More specifically, in order to provide a desired level of rigidity and strength of thevalve hole 106 and/or thewheel 200 overall, at least therim portion 204 of thewheel 200 may need to be relatively thicker or otherwise be reinforced as compared with corresponding features of thewheel 100. - Turning now to
FIGS. 3A and 3B , avalve stem assembly 300 is shown that may be installed to eitherwheel 100 orwheel 200. The valve stem assembly 300 may include avalve stem 302 that is mounted by way of a snap inmount 304. A tirepressure monitoring system 306 may be disposed within an interior portion I defined by thewheel 100 with respect to a tire (not shown) mounted to thewheel 100. The tirepressure monitoring system 306 may generally be configured to determine an air pressure within the interior portion I and/or communicate the air pressure to a controller or display (not shown) to allow remote monitoring of the tire pressure, e.g., from within the interior of a vehicle to which thewheel 100 is mounted. Themount 304 may generally define opposingshoulders shoulders shoulders shoulders wheels valve stem assembly 300 to thewheels shoulders valve stem assembly 300 into thevalve hole 106 and/or 206. - Referring now to
FIG. 3A ,wheel 100 with thevalve stem assembly 300 is described in further detail. As noted above, thelip 108 defines an axial thickness D1. Thevalve stem assembly 300 is generally supported within thevalve hole 106 by way of the snap-inmount 304, which is mounted on thelip 108. The mounting thickness of the snap-inmount 304, i.e., distance D5 between theshoulders lip 108 such that thevalve stem assembly 300 remained secured to thewheel 100. - Referring now to
FIG. 3B , thewheel 200 is illustrated with thevalve stem assembly 300. Theaperture 206 defines an axial thickness D2 that supports thevalve stem assembly 300. Notably, although different materials having different material strengths are used to form thewheel 100 and thewheel 200, a samevalve stem assembly 300 may be installed to each since the axial thicknesses D1 and D3 are each substantially equal to the mounting thickness D5 of themount 304. Accordingly, thelip 108 of thewheel 100 generally allows for a thicker interface with thevalve stem assembly 300 that corresponds to the greater thickness required in other wheels, e.g.,wheel 200. - Turning now to
FIG. 4 , an exemplary wheel blank 100′ is illustrated and shown prior to the forming of thevalve hole 106. A piercing operation may be used to form thevalve hole 106 and or thelip 108. The piercing operation may be carried out in a direction P such that thelip 108 extends to an exterior side of therim 104, e.g., as described above with regard towheel 100. In other words, a piercing or flaring operation may be carried out such that thelip 108′ formed thereby extends toward an exterior side E of the wheel blank 100′. Alternatively, the piercing operation may be carried out in an opposite direction, i.e., opposite to direction P, such that thelip 108 extends to an interior side I of therim 104 and/or wheel blank 100′. In one exemplary illustration, a refining process generally smooths a surface by removing burrs, edges, or other surface discontinuities that might otherwise damage wheel components such as a valve stem extending through an aperture of the wheel. In another example, a coining operation generally works upon one or more surfaces oflip 108 to remove burrs. While a coining operation may be advantageous as it works in a substantially uniform manner along the surface(s) of thelip 108, any other process may be employed that is convenient. - Turning now to
FIG. 5 , anexemplary process 500 of making a wheel is illustrated.Process 500 may begin atblock 502, where a first wheel blank is formed. For example, as shown above a wheel blank 100′ may be provided, which is a generally stamped steel wheel blank 100′. In one example, ahub portion 102 andrim portion 104 are each stamped from a sheet steel material, and subsequently secured together. - Proceeding to block 504, a lip may be formed in the first wheel blank. For example, as described above a piercing and/or flaring operation may be used to generally form a
lip 108 extending about the perimeter of thevalve hole 106.Process 500 may then proceed to block 506. - At
block 506, thelip 108 may be refined about the perimeter of thevalve hole 106. The lip may be refined in any manner such that the offsetsurface 110 is generally smoothed such that interference with avalve stem 302 is reduced or eliminated. For example, refinement of thelip 108 may generally remove sharp edges or burrs, e.g., as may result from the piercing operation used to form thevalve hole 106, which may otherwise damage thevalve stem 302. Thelip 108 may be refined in any manner that is convenient. In one exemplary illustration, a coining operation is used to generally smooth offsetsurface 110. In another example, as described above a refining process generally smooths a surface by removing burrs, edges, or other surface discontinuities that might otherwise damage wheel components such as a valve stem extending through an aperture of the wheel. In another example, a coining operation generally work upon one or more surfaces oflip 108 to remove burrs. While a coining operation may be advantageous as it works in a substantially uniform manner along the surface(s) of thelip 108, any other process may be employed that is convenient. In another example, a plastic flow may be induced along the surface of the wheel blank 100′ adjacent thevalve hole 106. The induced plastic flow of the sheet steel material along the surface of the wheel blank 100′ may generally refine the surface, e.g. offsetsurface 110 and/or an interior surface of thelip 108, thereby removing any sharp edges or burrs, which might otherwise interfere with or damaged thevalve stem 302. - Proceeding to block 508, a valve stem may be installed. For example, as described above a
valve stem assembly 300 may be installed to thevalve hole 106. The valve stem assembly 300 may generally be a snap in the stylevalve stem assembly 300, which generally simplifies installation. For example, as described above, the valve stem assembly may have abuttingshoulders baseline surface 112 and offsetsurface 110 of thelip 108.Process 500 may then proceed to block 510. - At
block 510, a second wheel may be provided. For example,wheel 200 may be formed or otherwise provided in any manner that is convenient. As noted above, thewheel 200 may have a baseline thickness D4 that is greater than a baseline thickness D2 of thefirst wheel 100. At the same time, an axial thickness D3 associated with thewheel 200 is substantially equal to the first wheel axial thickness D1. Accordingly, installation of a samevalve stem assembly 300, or at least valve stem assemblies having substantially the same mounting thicknesses, in each of thewheels Process 500 may then terminate. - In some exemplary approaches, the exemplary methods described herein may employ a computer or a computer readable storage medium implementing the various methods and processes described herein, e.g.,
