BACKGROUND OF THE INVENTION
The present invention relates to a vehicle wheel, spacers or separating means and tire carrying rims having radially inwardly projecting components thereon. The rims are dual mounted, inner and outer, on the wheel.
The vehicle wheel has a plurality of spaced-apart felloe portions for rim mounting and is preferably a spoked wheel. The spacers are non-compressible and comprise an individual element for each wheel felloe portion.
The prior art relating to vehicle wheels for carrying demountable rims and spacers or separating means therefor includes the patents to be found (the July, 1973, classification) in class 301, beginning with sub-class 10R. Generally relevant to the present invention are the patents relating to the mounting of plural or dual rims, inner and outer, normally found in sub-classes 13R and 13SM.
The accurate mounting of tire carrying rims on the felloe, felly or load bearing portion of a wheel has long been a problem in the art. Vehicle operators and industry regulations seek longer tire life and complete safety in operation, even under the most severe of vehicle operating conditions. The tire manufacturers are endeavoring to provide tires which have optimum performance characteristics, including lateral and radial balance. Consequently, it is being required that this art provide elements, the wheels, the rims, the fastening assemblies and the spacers, which do not deteriorate, hinder or impair the projected performance characteristics of the tires.
Heretofore, the wheel of a tire-rim-wheel assembly has been regarded primarily as a load carrying element attached to an axle of the vehicle and carrying the rim. The periphery of the wheel has felly surfaces to pilot or guide the rim into approximate mounting position. Thereafter, fastening means or assemblies are torqued down or tightened in such a manner that the tire carrying rim would not come loose from the wheel during use. If done correctly, as by an expert and conscientious mechanic, the prior art rim mounting techniques would not deteriorate, hinder or impair the performance characteristics of the tires. However, environmental or extrinsic factors such as warpage, deformation or damage to the rim and spacer or wear of the fastening means or assemblies could lead to relative displacement or non-alignment of the assembly components during fastening, creating conditions of what are now commonly referred to .[. as.]. excessive lateral (axial) or radial runout, or an imbalance of the tire-rim-spacer-wheel assembly during vehicle operation.
The inventors have determined that the concepts of vehicle wheel, spacers, tire carrying rims and fastening assemblies disclosed herein will permit of improved rim mounting techniques.
A wheel and spacers according to the invention, when used with rims and fastening assemblies adapted thereto, should reduce lateral (axial) and radial runout, resist rim warpage or deformation, restrict rim rotation relative to the wheel and spacers and provide better balance for the tire-rim-spacer-wheel assembly during vehicle operation.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an improved vehicle wheel, spacers, tire carrying rims and fastening assemblies adapted thereto.
It is a further object of the invention to provide an improved vehicle wheel and spacers for dual mounting of tire carrying rims having radially inwardly projecting components thereon. The mounting of such rims is greatly improved by creating and maintaining an operative relationship between the wheel felloe surfaces for rim seating, the location and position of the rims and spacer, and the location and function of the axially projecting components of the fastening assemblies for locking the rims and the spacers on the wheel.
These and other objects of the invention, as well as the advantages thereof, will be apparant in view of the detailed description of the various embodiments thereof as set forth below.
In general, a wheel according to the invention has a plurality of spaced-apart felloe portions. Each wheel felloe portion has a generally concave and axially extending pocket thereon for housing an axially projecting component of a fastening assembly for locking the rims and a spacer on the wheel. The axially inner end of each pocket has or terminates at a radially directed surface providing a mounting location for an axially projecting component of a fastening assembly. The radially directed surface intersects a radially inclined felloe surface for seating an inner rim. The axially outer end of the wheel felloe pocket has axially directed wing portions providing for dual axially oriented surfaces for seating an outer rim.
In general, a spacer according to the invention is non-compressible and comprises an individual element for each wheel felloe portion with a bore for receiving the shank of an axially projecting component of a fastening assembly for locking the rims on the wheel. .Iadd.
In general, a tire carrying rim with radially inwardly projecting components thereon comprises a radially inclined axially inner surface tapering toward an adjacent radially inwardly directed portion oriented substantially perpendicular to the rotational axis of the rim and having a bore therein for receiving the axially projecting component of a fastening assembly. .Iaddend.
One form of tire carrying rim according to the invention has radially inwardly projecting components for doweled and tenoned engagement with a spacer carried by the axially projecting component of a fastening assembly.

DETAILED DESCRIPTION OF THE INVENTION
A wheel according to the invention is referred to generally by the numeral 20. A wheel 20 may be used for mounting of tire carrying rims referred to generally by the numeral 21. Fastening assemblies referred to generally by the numeral 22 are used for locking the rims 21 on a wheel 20. A non-compressible spacer or separating means for the rims 21 when seated on the wheel 20 is referred to generally by the numeral 24.
As shown, a wheel 20 has a plurality of spaced-apart felloe, felly or load bearing portions referred to generally by the numeral 25. Preferably, each felloe portion 25 is carried by a spoke member 26 extending radially from a conventional hub area 27 for attachment of the wheel 20 to a vehicle axle (not shown). Alternatively, the wheel 20 could be disc-shaped or have a substantially continuous periphery with the felloe portions 25 being formed thereon at regularly spaced intervals.
A wheel felloe portion 25 has a generally concave and axially extending outwardly opening pocket thereon referred to generally by the numeral 28.
The axially inner end of a pocket 28 terminates at a radially directed surface 29. Each surface 29 has a mounting location indicated generally at 30 for an elongated axially projecting component of a fastening assembly 22. The radially outer end of each surface 29 intersects a radially inclined surface 31 for seating an inner rim 21. Each inclined surface 31 extends outwardly away from the rotational axis of the wheel at a suitable angle.
The axially outer end of a pocket 28 has spaced-apart axially projecting wing portions 32 providing for outwardly facing dual axially oriented surfaces 33 for seating an outer rim 21.
The medial sides of a pocket 28, between the radially directed surface 29 and the wing portions 32, have outwardly facing dual axially oriented surfaces 34, which may function to seat a spacer 24, as shown in FIGS. 1, 3 and 8, or the clamp lug (45) of FIG. 9.
.[.The.]. .Iadd.As shown, the .Iaddend.tire carrying rims 21 have a fixed bead flange (not shown) and a removable bead flange 36 for seating the beads (not shown) of a tire in a conventional manner. The removable bead flange 36 has a transversely split lock ring 37 carried by an annular rim base edge portion 38.
A rim base edge portion 38 has a radially inclined axially inner surface 39 intersecting an axially oriented radially inner surface 40 intersecting a radially directed axially outer surface 41. On an inner rim 21, the radially inwardly facing surface 39 may conform to and be seated on the radially inclined surface 31 of a felloe portion 25. On an outer rim 21, the surface 39 may conform to and be seated on a radially inclined surface on a stud supported movable clamp element of a fastening assembly 22.
With the exception of the conventional rims 21, as shown in FIG. 8, a rim base edge portion 38 has securely attached or connected thereto, as by welds 44, clamp lugs referred to generally by the numeral 45. The radially inwardly directed leg portion 46 of each clamp lug 45 has a bore 47 therein for receiving the elongated axially projecting component of a fastening assembly 22. A clamp lug 45 preferably has an axially oriented surface 50 intersecting a radially directed surface 51, securely attached to the conforming surfaces 40 and 41 on the rim base edge portion 38, as by welds 44.
The fastening assembly 22 comprises an elongated stud 52 extending axially of a felloe pocket 28, a clamp element 53 and a rotatable nut 54. As shown in FIGS. 1, 4, 7 and 8, the elongated stud 52 has an inner end with peripheral threads 55 for mating engagement with bore threads 56 at a mounting location 30. Alternatively, as shown in FIG. 11, the elongated stud 52 may have an inner end with a cap head 57 and peripheral serrations 58 for mating engagement with a bore 59 at a mounting location 30. Still alternatively, the elongated studs 52 may be attached at a mounting location 30 as by a conventional arc stud or capacitor-discharge welds.
A clamp element 53 has a bore 61 for receiving the elongated stud 52. A clamp element 53 also has lateral wing portions 62 providing downwardly facing dual axially oriented surfaces 63 for seating on conforming wheel felloe surfaces 33. The radially outer portion of a clamp element 53 has a radially inclined surface 64 for mating engagement with a conforming outer rim base edge portion surface 39.
Referring to FIG. 4, a clamp lug 45 may be modified according to the invention. As shown, the axially outer face of a leg portion 46 may have a concave area 65 formed coaxially around the bore 47 for mating engagement with a conforming surface on the ends of a spacer 22. Referring also to FIG. 9, a clamp lug 45 may also have lateral wing portions 66 adapted to extend radially on either side of a felloe pocket 28 and providing inwardly facing dual axially oriented surfaces 67 for seating on the wheel felloe surfaces 34.
Referring to FIGS. 4, 5 and 7, a clamp element 53 may be modified according to the invention. As shown, a clamp element 53 may have an axially inwardly directed member 68 for mating engagement against a clamp lug leg portion 46. Referring also to FIG. 8, the lateral wing portions 63 may have axially projecting dual extensions 69 providing for an axial extension of the surfaces 63 for seating on conforming wheel felloe surfaces 33.
Referring to FIG. 1, a spacer 24 according to the invention may have a radially inwardly projecting medial element 70 with a bore 71 therein for receiving the shank of an elongated stud 52 of a fastening assembly 22 and being retained thereby between the rims 21. As shown, the spacer 24 is generally T-shaped in cross section and for the purpose of weight reduction may have concave outer and under surfaces 72 and 73 tapered inwardly from lateral flange or marginal portions 74. The flange portions 74 each have radially directed edges for mating engagement with the opposed clamp lugs 45 carried by the inner and outer rims 21. As shown in FIG. 3, the length or radial extent of each such spacer 24 is such as to span the felloe pocket 28 and to seat the spacer on the felloe surfaces 34.
Referring to FIG. 4, a spacer 24 according to the invention may also be a cylindrical element having a bore 76 therein for receiving the shank of an elongated stud 52 of a fastening assembly 22 and being retained thereby between the rims 21. As shown, the spacer bore 76 may be cored as at 77 for the purpose of weight reduction. The spacer ends may have a convex area 78 formed coaxially around the bore 76 for mating engagement with the concave areas 65 on the clamp lugs 45 carried by the inner and outer rims 21. In this embodiment, the spacer elements 24 and clamp lugs 45 are in doweled and tenoned engagement around the elongated stud 52 of a fastening assembly 22 providing for a high degree of accuracy and precision in mounting and alignment of the inner and outer rims 21 on a wheel 20.
Referring to FIG. 7, a spacer 24 according to the invention may be another form of cylindrical element having a bore 76 therein for receiving the shank of an elongated stud 52 of a fastening assembly 22 and being retained thereby between the rims 21. As shown, the spacer bore 76 may be cored as at 77 for the purpose of weight reduction. The spacer ends may have radially directed surfaces 79 formed coaxially around the bore 76 for mating engagement with the opposed clamp lugs 45 carried by the inner and outer rims 21.
Referring to FIG. 8, a spacer 24 may be a prior art spacer as described and claimed in a co-pending U.S. patent application Ser. No. 530,532, .Iadd.now U.S. Pat. No. Re. 28,993 .Iaddend.to which reference is made for such further details as are necessary to understand the invention.
Referring to FIG. 12, a spacer 24 according to the invention may have a radially inwardly projecting medial element 80 with a bore 81 therein for receiving the shank of an elongated stud 52 of a fastening assembly 22 and being retained thereby between the rims 21. As shown, the spacer 24 is generally C-shaped in cross section and for the purpose of weight reduction may be a metal stamping with the medial element 80 secured to the under surface 82 as by a weld 83. This spacer 24 has lateral flange portions 84 with radially directed edges for mating engagement with the opposed clamp lugs (45) carried by the inner and outer rims (21). The length or radial extent of each such spacer 24 is such as to span the felloe pocket (28) and to seat the spacer on the felloe surfaces (34).
Referring to FIG. 13, a spacer 24 according to the invention may be another form of cylindrical element having a bore 86 therein for receiving the shank of an elongated stud 52 of a fastening assembly 22 and being retained thereby between the rims 21. As shown, the ends of the spacer bore 86 terminate in radially directed annular flanges 87 formed coaxially around the bore 86 providing a generally spool-shaped configuration for this spacer. This configuration is similar to the configuration of an element 11 as disclosed in U.S. Pat. No. 1,984,048, December /1934, class 301-13. The spacer flanges 87 are for mating engagement with the opposed clamp lugs 45 carried by the inner and outer rims 21.
In any embodiment of a rim 21, the clamp lugs 45 may be a series of individual elements. Alternatively, a clamp lug 45 may be an annular or substantially circumferentially continuous element having the radially inwardly projecting leg portions 46 thereon at spaced intervals.
In a wheel 20, the axially oriented surfaces 33 and 34, and the elongated axially projecting stud 52 of a fastening assembly 22, each preferably extend substantially parallel to the rotational axis of the wheel. Also, the radially directed surfaces 29 at the axially inner end of a felloe pocket 28 preferably extend substantially perpendicular to the rotational axis of the wheel.
