DETAILED DESCRIPTION OF THE INVENTION BACKGROUND OF THE INVENTION The present invention relates to a wheel having an outer edge surface for attachment of a tire retaining rim.

According to the invention, the tire retaining rim has a corresponding rim and the mounting have a flange surface, and these rims and the mounting have an engagement between them because the flange surface is elastically deformed during fixation to the outer edge surface. will be ensured.

The invention also relates to a wheel having a single rim for holding a tire and spoke members for attaching its fastening means.

In a dual-wheel embodiment without a spacer, or in a single-wheel embodiment, the rim holding the tire has a radially inwardly projecting part that is engaged by a fastening means or assembly. Each fastening means or fastening assembly has an axially projecting part.

In one embodiment (FIGS. 13 to 18), the rim carrying the tire is seated on a varying surface and has a radius arranged in relation to an axially projecting part of the fastening means or fastening assembly. It has a flange that protrudes inward.

In another embodiment (FIGS. 19 to 24), the rim carrying the tire is seated on a changing surface and is disposed in relation to the axially projecting part of the fastening assembly and projects radially inwardly. The mounting has the rim proximal end portion also seated on the flange.

In yet another embodiment (Figures 27-38), the rim for holding the tire has a rim base including a radially inclined surface for seating the rim on the outer edge of the wheel, and an axial surface. , radially extending surfaces, and a pair of clamp plugs having radially inwardly facing leg portions are secured together to the radially extending surfaces, the leg portions of the fastening assembly. It is arranged in relation to an axially projecting portion and a radially extending surface on the outer edge of the wheel.

It is also desirable that the clamp plug be integrally fixed to the rim surface along the axial direction.

Precise attachment of tire retaining rims to the outer edge, or load bearing portion, of a wheel has long been a problem in the art.

Vehicle driver differences and industry regulations require longer tire life and
They want complete operational safety guaranteed even under the harshest vehicle operating conditions.

Tire manufacturers strive to produce tires with optimal performance characteristics, including lateral and radial balance.

Accordingly, there is a need in the art to provide components, wheels, rims and fastening means or assemblies that do not degrade the intended performance characteristics of the tire.

Until now, spoked wheel structures of tire-rim-wheel assemblies have been considered to be primarily load-bearing parts fixed to the axle of a vehicle and to hold the rim.

The circumference of the wheel had an outer edge surface to guide the rim into approximate mounting position.

The fastening means or assembly was then tightened to prevent the tire retaining rim from loosening from the wheel during use.

If done correctly by a skilled person or an honest mechanic,
Prior art rim mounting techniques do not degrade, interfere with, or impair the performance characteristics of the tire.

However, for example warping, deformation or damage to the rim and spacer, or wear of the fastening means (fastening assembly) may create conditions during the fastening or what is currently commonly referred to as excessive lateral (axial) or radial runout. At times, this can lead to relative displacements of assembly parts, ie, misalignment, and can lead to unbalance of the tire-rim-wheel assembly when the vehicle is operated.

During operation of the vehicle, the shape and position of the seating surface which receives lateral thrust or radial loads on the rim and the position of the axially projecting parts of the rim fastening means or rim fastening assembly that secure the rim to the spokes of the wheel. It was found that there was a significant relationship between

The present invention provides an improved rim mounting technique for a wheel outer surface, a tire retention rim, and a fastening means or assembly for use therewith.

Wheel and tire retaining rims according to the invention, when used with suitable fastening means or assemblies, actively control and reduce lateral (axial) and radial run-out of the rim. It resists warping or deformation, eliminates the possibility of rotation of the rim with respect to the wheel, and improves the balance of the tire-rim-wheel assembly during wheel motion.
