Description

BACKGROUND

Exemplary embodiments herein relate to a temporary or spare tire assembly for a vehicle. More particularly, exemplary embodiments herein relate to a spacer for use with a temporary or spare tire assembly.

Due to market, supplier, or regulation changes over a vehicle production life cycle, there is a potential for a change in a packaging layout for the vehicle since production startup. For example, the supplier of the temporary, or spare, tire may change during the vehicle production life cycle. The change in supplier can result in the use of a different tire than the tire originally used during development while setting up the packaging layout for the vehicle. Such a change in tire size can result in the spare wheel assembly not fitting the same within the spare wheel compartment as compared to the original design. Such a change in design may result in a tire rim of the spare wheel assembly contacting the floor of the spare wheel compartment resulting in an undesirable rattling noise.

In view of the foregoing, a spacer for spacing a spare wheel assembly from a vehicle floor of a vehicle compartment is provided. The spacer includes an annular body, an outer flange, and an inner flange. The annular body includes an upper surface for facing toward the spare wheel assembly and a lower surface for facing toward the floor and away from the spare wheel assembly. The annular body further includes a peripheral edge and an inner edge. The outer flange extends from the upper surface and is configured to contact a wheel rim of the spare wheel assembly. The inner flange is offset radially inwardly from the outer flange and extends from the upper surface. The inner flange is configured to contact the wheel rim of the spare wheel assembly offset from where the outer flange is configured to contact the wheel rim.

A spare wheel assembly and a spacer in combination is also provided. The spare wheel includes a tire and a wheel rim. The tire is mounted to the wheel rim and includes two sidewalls and a central section extending axially between the two sidewalls. The wheel rim includes a cylindrical section and a center piece.

FIG. 1 depicts a spare wheel assembly 10 and a spacer 12 disposed in a vehicle compartment 14 having a floor 16. The spacer 12 can appropriately position the spare wheel assembly 10 from the vehicle floor 16 to prevent undesirable rattling. In addition, the spacer 12 can also be used to fix and/or properly position the spare wheel assembly 10 within the vehicle compartment 14.

The spare wheel assembly 10 can be similar to conventional spare wheel assemblies, which are typically found to be stored in a trunk compartment or other suitable compartment of a vehicle. The depicted spare wheel assembly 10 includes a tire 20 and a wheel rim 22. The tire 20 mounts to the wheel rim 22 in a conventional manner. The tire 20 includes two sidewalls, i.e., an interior sidewall 24 and an exterior sidewall 26, and a central section 28 extending axially between the two sidewalls 24, 26. The central section 28 carries the tread (not shown) of the tire 20.

The wheel rim 22 includes a cylindrical section 32 and a center piece 34. The cylindrical section 32 includes an internal flange 36 and an external flange 38 axially spaced from the internal flange. The cylindrical section 32 further includes an internal step portion 42 and an external step portion 44 axially spaced from the internal step portion 42. A central well 46 is disposed between the internal step portion 42 and the external step portion 44. The tire 20 mounts to the cylindrical section 32 of the wheel rim 22 with the respective sidewall 24, 26 being received within and pressed against the respective flange 36, 38. In the illustrated embodiment, the center piece 34 connects with the cylindrical section 32 of the wheel rim 22, but can be integrally formed with the cylindrical section 32. The center piece 34 includes a plurality of bolt holes 48 (FIG. 5), which allow the spare wheel assembly 10 to mount to a wheel hub of the vehicle in a conventional manner.

With reference to FIGS. 2-4, the spacer 12 includes an annular body 62 including an upper surface 64 and a lower surface 66. With reference back to FIG. 1, the upper surface 64 of the annular body 62 faces toward the spare wheel assembly 10 when the spacer 12 is properly located within the vehicle compartment 14 resting on the floor 16. The lower surface 66 faces toward the floor 16 and away from the spare wheel assembly 10 when the spacer 12 is properly located within the vehicle compartment 14 resting on the floor 16. In the depicted embodiment, the upper surface 64 is substantially flat or planar, though this is not required. Also in the illustrated embodiment, the lower surface 66 of the annular body 62 is corrugated (see FIGS. 1 and 3), though this is not required. As such, the lower surface 66 includes a plurality of annular ridges 68, which define a plurality of annular grooves 72. In an alternative arrangement, the annular body 62 could be corrugated such that annular ridges and grooves would also be provided on the upper surface of the annular body. In any embodiment, the spacer 12 can be made from a rigid material, such as a rigid plastic, and the general thickness, e.g. the thickness between the upper surface 64 and the lower surface 66, can be about 3 mm.

The annular body 62 further includes a peripheral edge 74 and an inner edge 76. In the illustrated embodiment, the peripheral edge 74 is circular and follows the radius of a center point 78. The inner edge 76 defines a central opening 82. As shown in FIGS. 2 and 4, for the illustrated embodiment the inner edge 76 of the annular body 62 is substantially circular and the annular body includes a plurality of inward projections 84 each projecting radially inwardly from the inner edge 76 toward the center point 78. The projections 84 interrupt the circularity of the inner edge 76.

As more clearly seen in FIG. 4, the lower surface 66 of the annular body 62 at each projection 84 is planar or flat. As more clearly seen in FIG. 1, the lower surface 66 of the annular body 62 at the inward projection 84 is co-planar with the planar surface defined by the groove 72. As illustrated, the annular body 62 includes four inward projections 84 where each inward projection is angularly spaced, with respect to the center point 78, about 90 degrees from each adjacent inward projection. A fewer or greater number of inward projections 84 can be provided and the angular space between the inward projections can be changed.

The spacer 12 also includes an outer flange 90 extending from the upper surface 64 of the annular body 62. In the illustrated embodiment, a plurality of outer flanges (four outer flanges are shown in the illustrated embodiment, though more or fewer could be employed) are provided each extending from the upper surface 64 of the annular body 62. With reference back to FIG. 1, each outer flange 90 is configured to contact the wheel rim 22 of the spare wheel assembly 10. The spacer 12 also includes an inner flange 92 extending from the upper surface 64 of the annular body 62. In the illustrated embodiment, a plurality of inner flanges 90 are provided. Each inner flange 90 is offset radially inwardly from a respective outer flange 92. Each inner flange 92 is configured to contact the wheel rim 22 of the spare wheel assembly 10 offset from where the outer flanges 92 are configured to contact the rim. The plurality of outer flanges 90 and the plurality of inner flanges 92 act in concert to maintain the spare wheel assembly 10 securely within the vehicle compartment 14 and to also space the wheel rim 22 from the floor 16 of the vehicle compartment.

As most clearly visible in FIG. 3, each outer flange 90 includes a free end 94 spaced from the upper surface 64 of the annular body 62. With reference back to FIG. 1, the free end 94 of each outer flange 90 contacts at least one of the internal flange 36 and the external flange 38 of the wheel rim 22. In the illustrated embodiment, the free end 94 of the outer flange 90 contacts the external flange 38. If the spare wheel assembly 10 were turned 180 degrees, e.g., flipped, from the orientation shown in FIG. 1, the free end 94 of the outer flange 90 may contact the internal flange 36 of the wheel rim 22. With reference to FIGS. 2 and 3, each outer flange 90 extends substantially perpendicularly from the upper surface 64 of the annular body 62. As most clearly seen in FIG. 2, the outer flange 90, or at least the free end 94 of the outer flange, follows a circular arc having a radius emanating from the center point 78. This allows the free end 94 to engage the internal flange 36 or the external flange 38, which is typically circular when viewed normal to the rotational axis of the spare wheel assembly 10.

As indicated above and as shown in the illustrated embodiment, a plurality, more particularly four, outer flanges 90 are provided on the spacer 12. As illustrated, each outer flange 90 is angularly spaced about 90 degrees from the adjacent outer flange with respect to the center point 78. A fewer or greater number of outer flanges may be provided and the angular spacing between the outer flanges can be changed. As illustrated, each outer flange 90 is substantially aligned with the inner edge 76 of the annular body 62.

As mentioned above, the spacer 12 also includes an inner flange 92 offset radially inwardly from the outer flange 90 and extending from the upper surface 64 of the annular body 62. The inner flange 92 (a plurality of inner flanges are shown in the illustrated embodiment) is configured to contact the wheel rim 22 of the spare wheel assembly 10 offset from where the outer flange 90 is configured to contact the wheel rim. As more clearly seen in FIG. 3, each inner flange 92 includes a distal end 96 that is spaced from the upper surface 64 of the annular body 62. As most clearly seen in FIG. 1, the distal edge 96 of each inner flange 92 contacts at least one of the internal step portion 42 and the external step portion 44 of the cylindrical section 32 of the wheel rim 22. As shown in FIG. 1, the distal edge 96 of each inner flange 92 contacts the external step portion 44. If the spare wheel assembly 10 were to be rotated 180 degrees, e.g., flipped, from the orientation shown in FIG. 1, then the distal edge 96 could contact the internal step portion 42 of the cylindrical section 32 of the wheel rim 22.

As most clearly seen in FIG. 3, each inner flange 92 extends upwardly from the upper surface 64 of the annular body 62 and radially toward the peripheral edge 74 of the annular body 62. Each inner flange 92 extends farther from the upper surface 64 of the annular body 62 as compared to the outer flanges 90. Accordingly, the distal end 96 of each inner flange 92 is spaced farther from the upper surface 64 of the annular body 62 as compared to the free end 94 of each outer flange 90. As most clearly seen in FIG. 2, the respective distal ends 96 of the inner flanges 92 follow a circular arc having a radius emanating from the center point 78. This allows each distal end 96 to contact the internal step portion 42 or the external step portion 44, which is generally circular when viewed normal to the rotational axis of the spare wheel assembly 10. Also in the illustrated embodiment, each inner flange 92 extends from a respective inward projection 84.

The outer flange 90 and the inner flange 92 can be made from the same material as the annular body 62, e.g., metal or a durable plastic. The inner flange 92 can be made from a material that allows the inner flange to flex with respect to the annular body 62 when the distal ends 96 of the inner flanges 92 engage the wheel rim 22. This can provide a friction fit along the external step portion 44 (with regard to the embodiment shown in FIG. 1) to retain the spare wheel assembly 10 against the spacer 12. As most clearly seen in FIG. 2, a plurality of gussets 98 can also be provided to strengthen a respective internal flange 92. In the depicted embodiment, a plurality of gussets 98 are provided with each respective inner flange 92 to connect an upper surface 102 of each respective inner flange 92 with the upper surface 64 of the annular body 62.

In the illustrated embodiment, a plurality of inner flanges 92 are provided. As illustrated, each inner flange 92 is angularly spaced about 90 degrees from each adjacent inner flange. As such, the illustrated embodiment includes four inner flanges. In an alternative arrangement, a fewer or greater number of inner flanges can be provided. As illustrated, each outer flange 90 is substantially aligned with a respective inner flange 92. In other words, in the illustrated embodiment, outer flanges 90 are positioned at the 12 o'clock, the 3 o'clock, the 6 o'clock, and the 9 o'clock position as shown in FIGS. 2 and 4 and inner flanges 92 are also positioned at the 12 o'clock, the 3 o'clock, the 6 o'clock, and the 9 o'clock position. The outer flange 90 depicted in FIG. 1 is configured to contact the wheel rim 22 axially offset (with respect to the rotational axis of the spare wheel assembly 10) from where the inner flange 92 depicted in FIG. 1 is configured to contact the wheel rim. The outer flange 90 depicted in FIG. 1 is also configured to contact the wheel rim 22 radially offset from where the inner flange 92 depicted in FIG. 1 is configured to contact the wheel rim. This allows the flanges 90, 92 to work in concert to retain spare wheel assembly 10 within the vehicle compartment 14.

The annular body 62 also includes a plurality of apertures 110. As illustrated, each respective aperture 110 is positioned between a respective outer flange 90 and a respective inner flange 92. Each aperture 110 is also located within a respective inward projection 84 of the annular body 62. Each aperture extends through the annular body 62 from the upper surface 64 through to the lower surface 66. Were the annular body 62 to be made from metal, each aperture 110 could be formed by punching, which would allow the inner flange 92 to be made from material that was punched from the annular body such that the inner flange is separated from the annular body along three sides thereof while one edge is still connected to the annular body.
