Description

The present invention relates to a combination of a 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.

Prior art patents particularly relevant to rims, wheels and fastening assemblies according to the invention include references cited during the pendency of U.S. application Ser. No. 592,502. Other prior art relating to tire carrying rims demountably carried on vehicle wheels includes patents to be found in Class 301 beginning with Subclass 10R. Other relevant patents may be found in Class 152, Subclasses 406X et seq.

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, and fastening assemblies 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 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, fastening 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 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 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-wheel assembly during vehicle operation.

This application, and the referenced prior application, provide the art with various embodiments of base flanged rims and fastening assemblies therefor which, when used with the wheel adapted thereto, positively control and reduce lateral (axial) and radial runout, resist rim warpage and deformation, restrict or lock out the possibility of rim rotation relative to the wheel and provide better balance for the tire-rim-wheel assembly during vehicle operation.

This application, and the referenced prior application, also provide the art with complete interchangeability of a particular rim embodiment with a 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 an inner or outer dual.

The referenced prior application discloses wheels with radially inclined inner dual wheel felloe surfaces. It has now been found that the same 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 an 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 surfaces. As a result, this application discloses various embodiments 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 a 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, interchangeble for use as an inner or outer dual, having base attached mounting flanges or adaptors seated or locked on wheels adapted thereto having dimensioned 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.

In all embodiments disclosed herein, the wheel spoke members each 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.

Each mounting flange further has a medial portion comprising a radially inclined axially inner surface intersecting an axially oriented radially inner surface. Each mounting flange still further has a radially inwardly directed terminal or leg portion adjacent an axially oriented surface and oriented substantially perpendicular 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.

In all embodiments disclosed herein, the fastening assemblies for use in mounting a tire carrying rim on an inner dual wheel comprise an axially projecting component and a rotatable nut carried thereon for bearing engagement against the axially outer face of a clamp lug leg portion.

The fastening assemblies for use in mounting a tire carrying rim on an outer dual wheel comprise an axially projecting component and a clamp element and a rotatable nut carried thereon.

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.

In the FIG. 1 and FIG. 4 embodiments, initial tightening of the fastening assemblies will seat the axially oriented mounting flange surfaces on each rim in concentric radial registry with conforming axially oriented surfaces. In both the FIGS. 6 and 7 embodiments, initial tightening of the fastening assemblies will seat the radially inclined mounting flange surfaces in concentric registry with conforming radially inclined clamp element surfaces.

In all embodiments, final tightening of the fastening assemblies to apply a load will lock the rim on the wheel, in lateral (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.

In the FIGS. 1-3 embodiment, a wheel is indicated generally by the numeral 120, the dual inner and outer carrying rims are indicated generally by the numeral 121, the inner rim fastening assemblies are indicated generally by the numeral 22 and the outer rim fastening assemblies are indicated generally by the numeral 122.

A dual wheel 120 has a plurality of alternating inner and outer spoke members, 123(I) and 123(O), with an axially spaced-apart and staggered relation to an adjacent spoke member. Each spoke member extends radially from a conventional hub area 124 and terminates in a felloe portion. The inner felloes are referred to generally by the numeral 125(I); the outer felloes are referred to generally by the numeral 125(O).

Each wheel felloe 125(I) and 125(O) has a predetermined mounting location indicated generally at 26 for the axially projecting component of a fastening assembly 22 or 122. As shown, the axially projecting component of a fastening assembly 22 or 122 is a stud 27 having an inner end with peripheral threads 28 for mating engagement with bore threads 29.
