Description
2~3 BACKGROUND OF THE INVENTION
. .
The present invention relates to a combination of at least one tire carrying rim seated and locked by fastening assemblies on a vehicle wheel. A combination of dual inner and outer tire carrying rims may be mounted on a vehicle wheel without using a separating means, such as an annular spacer.
The accurate mounting of tire carrying rims on the felloe, elly or load-bearing portion of a wheel has long been a problem in the art. Vehicle operators and industry regula-tions 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, includincj lateral and ra-dial balance. Consequently, it is being required that this art provide elements, the wheels, the rims, and fastening assem-blies therefor, which do not deteriorate, hinder or impair the projected performance characteristics of the tires.
Heretofore, the spoked wheel structure of a tire-rim-wheel assembly has been regarded primarily as a load carrying 2~ element attached to an axle of the vehicle and carrying the rim.
The periphery of the wheel had felly surfaces to pilot or guide the rim into approximate mounting position. Thereafter, fas-tening assemblies were 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 impaif the performance char-acteristics of the tires. However, environmental or extrinsic 1~ 2~3 factors such as warpage, deformation or damage to the rim and spacer or wear of the fastening assemblies could lead to relative displacement or non-alignment of the assembly com-ponents 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-wheel assembly during vehicle operation.
This application provides the art with various em-bodiments of base flanged rims and fastening assemblies there-for which, when used with the wheel adapted thereto, positivelycontrol and reduce lateral (axial) and radial runout, resist rim warpage and deformation, restrict or lock out the possibil-ity of rim rotation relative to the wheel and provide better balance for the tire-rim-wheel assembly during vehicle opera-tion.
This application also provides the art with completeinterchangeability of a particular rim embodiment with either a single or dual wheel adapted thereto. So long as the wheels and a particular rim embodiment are matched according to the subject matter disclosure, a rim can be used as either a single or inner or outer dual.
It has now been found that improved results can be achieved without the use of radially inclined wheel felloe surfaces- while maintaining the advantages of complete rim interchangeability, for use as either a single or inner or outer dual. This improved subject matter concept permits the use of a lighter weight, less expensive wheel and is thought to be particularly efficient or effective when relatively light mounting flanges attached to the rim base edge portion are piloted by axially oriented wheel felloe surfaces or axially oriented fastening assembly surfaces during tightening of the fastening assemblies and mating engagement with mounting sur-faces. As a result, this application discloses various embodi-ments of middle range tire-rim-wheel assemblies useful in light or medium duty vehicle applications.
SUMMARY OF THE INVENTION
The object of the invention is to provide an improved combination of at least one tire carrying rim seated and locked by fastening assemblies on a vehicle wheel.
It is a further object of the invention to provide tire carrying rims, interchangeable for use as a single or inner or outer dual, having base attached mounting flanges or adap-tors seated or locked on wheels adapted thereto having dimen-sioned felloe surfaces and by coacting fastening assemblies.
It is a further object of the invention to provide interchangeable base flanged tire carrying rims which can be seated and locked by fastening assemblies on a vehicle wheel without the use of radially inclined wheel felloe surfaces.
These and other objects of the invention, as well as the advantages thereof, will be apparent in view of the detailed description thereof as set forth below.
The wheel spoke members have felloes comprising a radially inwardly directed surface substantially perpendicular to the rotational axis of the wheel and providing a mounting location for an axially projecting component of the fastening assemblies. The outer dual spoke members may also have felloes j .
with a radially inner axially oriented lateral surface for piloting of conforming fastening assembly clamp element sur-faces.
The tire carrying rims have radially outwardly pro-jecting bead flanges and radially inwardly projecting mounting flanges. Each mounting flange has a radially outer portion integrally attached to a conforming annular surface on a base portion of the rim between the bead flanges. Each mounting flange further has a medial portion comprising a radially in-clined axially inner surface intersecting an axially orientedradially inner surface. Each mounting flange still further has a radially inwardly directed terminal or leg portion adjacent ., an axially oriented surface and oriented substantially perpen-dicular to the rotational axis of the rim having a bore therein ;-` for receiving the axially projecting component of the fastening ,; assemblies.
~": :
Each mounting flange leg portion has a bore with an effective diameter greater than the effective diameter of the axially projecting component of the fastening assemblies.
The fastening assemblies for use in mounting a tire carrying rim comprise an axially projecting component and a clamp element and a rotatable nut carried thereon. Each clamp element has a bore therein for receiving the axially projecting component of the fastening assemblies. The clamp element bore may have an effective diameter greater than the effective diameter of the axially projecting component. Alternatively, the clamp element bore has an effective diameter coincident with the effective diameter of a medial portion on the axially projecting component.
2~3 The clamp element may have dual segmental axially movable surfaces; a radially outer radially inclined surface and a radially inner axially oriented surface; and, parallel axially movable radially directed surfaces.
-In general, the tire carrying rims are seated on, and thereafter locked on, a wheel by initial and final tightening of the fastening assemblies against each clamp lug leg portion.
Initial tightening of the fastening assemblies will ~-seat the radially inclined mounting flange surfaces in con-centric registry with conforming radially inclined clamp ele-ment surfaces.
Final tightening of the fastening assemblies to apply a load will lock the rim on the wheel, in la.eral (axial) and radial alignment and registry relative to the rotational axis of rim and wheel, by the full surface engagement of the clamp lug leg portions with the radially directed wheel felloe surfaces.
