Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of U.S. patent
application Ser. No. 16/807,209 filed Mar. 3, 2020, which is a
continuation of U.S. patent application Ser. No. 15/648,517 filed
Jul. 13, 2017, which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The present invention relates generally to the field of
tires and wheel/tire assemblies.
Description of the Prior Art
[0003] A variety of wheel rim/tire assemblies are provided for use
in different environments with different surfaces supporting the
wheel rim/tire assembly. Separate problems exist in the case of
such assemblies for supporting a tractor, trailer or other type of
vehicle driven across rough ground, such as found in an
agricultural environment. In many cases, the rim and tire have a
relatively large diameter allowing for possible relative movement
between the rim and tire as the wheel encounters variations in the
terrain including ridges and rocks. It is the custom to provide a
rim having outer circumferentially extending and mutually facing
rim edges that clinch tightly on the opposite sides of the tire
providing a unified assembly. Disclosed herein is a means of
attaching the tire to the rim by means of tabs or flanges
integrally connected to the tire and then fastened directly to the
wheel rim thereby limiting relative motion between the tire and
rim. Further, and in particular in an agricultural environment, the
tire and rim may accumulate mud from the field as the wheel is
driven across the field. The tire disclosed herein includes a
circumferentially extending portion that extends outwardly from the
main body of the tire and rim with the portion being flexible
thereby shaking off the mud as the wheel is rotated. An additional
problem occurs when removing the bearing provided in the wheel hub
mounted to the vehicle axle. As the result, the tire in many cases
must be removed from the rim with the rim then being disassembled
to allow for the removal of the bearing. The assembly disclosed
herein has a bearing that may be removed from the wheel without
requiring either the removal of the tire from the rim or the
disassembly of the rim.
SUMMARY OF THE INVENTION
[0004] On embodiment of the present invention is a wheel assembly
that is mountable to a vehicle. A first wheel disc has a first
circular rim with a first outer portion and a first hub with a
first central opening. A second wheel disc has a second circular
rim with a second outer portion and a second hub and a second
central opening. First fasteners extend from the first hub to the
second hub securing the first wheel disc to the second wheel disc
and forming a wheel rim so the first central opening is aligned
with the second central opening with a central rotational axis. A
tire with a main body is attached to the wheel rim and clinched
between the first outer portion and the second outer portion of the
first wheel disc and the second wheel disc facing each other.
Second fasteners attach the tire to the wheel rim.
[0005] Another embodiment of the present invention is a wheel rim
for mounting a tire to a vehicle. A first wheel disc has a first
circular rim and a first hub with a first central opening. A second
wheel disc has a second circular rim and a second hub and a second
central opening. Fastening means are connected to the first hub and
to the second hub securing the first wheel disc to the second wheel
disc together forming a wheel rim so the first central opening is
aligned with the second central opening defining a central
rotational axis of the wheel rim. Fasteners extend through the tire
and the wheel rim to secure the tire to the wheel rim; and wherein
the first wheel disc is secured to the second wheel disc and
defines a tire receiving clinching space therebetween.
[0006] Yet a further embodiment of the present invention is a tire
for mounting to a wheel rim in turn mountable to an axle of a
vehicle. The tire main body surrounds the wheel rim with the main
body including an inwardly facing surface and an outwardly facing
surface with a first exterior side surface and a second exterior
side surface extending between the inwardly facing surface the
outwardly facing surface. The main body includes a plurality of
flanges projecting inwardly with the flanges fixedly connectable to
the wheel rim limiting relative motion between the tire and the
wheel rim.
[0007] It is an object of the present invention to provide a tire
that will minimize the accumulation of dirt and mud thereon.
[0008] A further object of the present invention is to provide a
wheel rim and tire assembly that provides a fixed connection
between the tire and rim minimizing relative motion therebetween to
prevent the tire from rolling off the wheel rim while allowing the
tire to be flexible relative to the wheel rim shaking off any dirt
thereon.
[0009] A further object of the present invention is to provide a
wheel rim/tire combination having a centrally located bearing that
is easily removable.
[0010] A further object of the present invention is to provide a
tire having tabs attaching the tire to the rim with the tire having
a flexible outer portion cooperatively allowing and creating
flexibility in the tire that will shake mud and dirt from the
wheel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] For the purposes of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiments illustrated in the drawings and specific language will
be used to describe the same. It will nevertheless be understood
that no limitation of the scope of the invention is thereby
intended, such alterations and further modifications in the
illustrated device, and such further applications of the principles
of the invention as illustrated therein being contemplated as would
normally occur to one skilled in the art to which the invention
relates.
[0023] Referring in particular to the drawings, the preferred
embodiment of wheel 30 is shown in FIGS. 1 and 2. A front view of
the assembly which is the side of the assembly facing outward is
shown in FIG. 1 whereas the inwardly facing side facing the vehicle
upon which the assembly is mounted is shown in FIG. 2. Many
variations of tires are available and can be used in the instant
combination. For example, the tire may or may not be inflated and
typically will be hard or soft depending upon whether the user,
such as a farmer has soft or hard ground. The tire 31 (FIG. 4)
includes a plurality of tabs or flanges 35 integrally attached to
the main body 36 of the tire. Flanges 35 extends radially inward
and are attached to the wheel rim 32 (FIG. 2).
[0024] Referring now more particularly to FIGS. 6-9, a first wheel
disc 33 will now be described it being understood that an identical
description applies to the second wheel disc 34 with the exception
that disc 34 includes a recess for receiving a snap ring adjacent
the wheel bearing whereas disc 33 has a shoulder to receive the
bearing as will be described later in the specification. Disc 33
has a first circular continuous rim 38 joined to a central hub 39
by radially extending spokes 40. The opposite ends of the spokes
are integrally joined to circular rim 38 and hub 39. Hole 41
extends centrally through hub 39 and defines the axis 42 (FIG. 10)
of rotation of the wheel. The continuous outer portions 38 of each
wheel disc 33 and 34 are indented forming shoulders 43 (FIGS. 7 and
10) to receive a reduced portion 44 of the main body of tire
31.
[0025] Fastener holes extend through hub 39 and the outer portion
38 of wheel disc 33 to receive fasteners securing wheel disc 33 and
34 together as well as securing the radially inwardly extending
flanges 35 to the wheel rim. In the embodiment shown in the
drawings, hub 39 includes three holes 45 extending therethrough to
receive fasteners for securing the hub to the adjacent hub of wheel
disc 34. In addition, the outer portion 38 of disc 33 includes six
holes 46 to receive fasteners extending through disc 33 and then
through the tire flanges with the fasteners then extending through
the outer portion of disc 34.
[0026] A plurality of tire flange receiving areas or recesses 47
(FIG. 7) are formed on the inwardly facing side of the outer
portion of disc 33 with each recess 47 being aligned with a
corresponding fastener hole 46. In addition, pegs 48 are mounted to
the inwardly facing side of disc 33 and project towards and into
disc 34.
[0027] In the embodiment in the drawings, a total of three fastener
holes 45 are shown in hub 39 and six fastener holes 46 are shown on
the outer portion of the disc it being understood that the number
of fastener holes can be varied and is included in the present
invention. Further, three pegs 48 are shown mounted to the inwardly
facing side of disc 33 to project into complimentary sized holes in
the mutually facing side of disc 34 which includes three additional
pegs that extend from disc 34 and into disc 33. Thus, a total of
six pegs lock the first wheel disc 33 and the second wheel disc 34
together with recesses 47 being spaced between pegs 48 and peg
holes 46. In an embodiment shown in FIG. 7, either a peg 48 or a
peg hole 46 is provided between adjacent recesses 47 of disc 33 and
disc 34.
[0028] Tire 31 (FIG. 4) is mountable to the wheel rim composed of
wheel disc 33 and 34 secured together. Tire 31 includes a main body
50 with an outwardly facing tread surface 51 for directly engaging
the ground or other surface upon which the tire moves. Further,
main body 50 has an inwardly facing surface 52 in contact with the
wheel rim. Tabs or flanges 35 are an integral part of main body 31
and project radially inward towards the rotational axis 42. Each
flange 53 includes a hole 53 through which a fastener extends to
connect the tire directly to the opposing wheel disc 33 and 34. A
first exterior side surface 54 (FIG. 10) and a second exterior side
surface 55 extend between the inwardly facing tire surface 52 and
the outwardly facing tire surface 51. The tire may be hollow or
solid depending upon the particular application. Flange 35 projects
inwardly from surface 52.
[0029] The wheel rim is assembled by placing the interior surfaces
56 of disc 33 and 57 of disc 34 together so that the outer portion
38 of disc 33 and the outer portion 68 of disc 34 face outwardly
thereby forming the wheel rim. The tire 31 is mounted to the wheel
rim by extending the flanges 35 into the aligned recesses 47 (FIG.
7) of adjacent wheel discs 33 and 34. Thus, the recesses 47 of disc
33 must be aligned and positioned immediately across from the
recesses 47 of wheel disc 34. Fasteners 60 (FIG. 10) are then
extended into recesses 47. For example, the shank of fastener 60
(FIG. 10) is first extended through the hole 46 of wheel disc 34
with the shank then passing through flange 35 of the tire and then
exiting the flange passing through the aligned hole 46 of disc 33
wherein a fastening nut 69 is threaded onto the shank of the bolt
with the head of the bolt being located in recess 47 of disc 34. In
this manner, all of the inwardly extending flanges 35 of the tire
are extended into the mutually facing recesses 47 (FIG. 3) and then
secured therein by the fasteners 60.
[0030] Agricultural tires are customarily mounted to their wheel
rims by fitting the main body of the tire between the
circumferentially extending mutually facing rims which are then
tightened together to clinch the tire main body therebetween. Thus,
as shown in FIG. 10, the circumferentially and outer extending edge
portions 61 of the wheel discs are mutually opposed forming
shoulders 43 in contact with the inwardly projecting portion 62 of
the tire main body. As fasteners 60 are tightened, the mutually
facing shoulders 43 of wheel discs 33 and 34 are moved towards each
other thereby clinching and holding the inwardly projecting portion
62 of the tire therebetween. Securing flanges 35 directly to the
wheel rim via fasteners 60 adds further stability to the wheel
rim/tire assembly limiting relative motion between the wheel rim
and the tire. Flange 35 is therefore sandwiched between the disc 33
and 34 once the flanges are inserted into the recesses 47 and
secured thereto.
[0031] Fasteners 70 (FIG. 10) are extended through the mutually
facing holes 45 of disc 33 and 34 securing the two discs together
and forming the wheel rim. For example, the shank of fasteners 70
is extended into hole 45 of disc 34 and then into the aligned hole
45 of disc 33 being secured thereto by a conventional fastening nut
with the head of the bolt being located within the recess provided
in disc 34.
[0032] The main body 50 of tire 31 has an overhanging flexible
portion 71 that extends outwardly of the remaining portion of the
entire main body. Further, the overhanging portion can extend
outwardly of the wheel rim. The overhanging portion 71 is integral
with the tire main body and has a thickness 72 considerably less
than the thickness of the remaining portion of the tire.
Overhanging portion 71 extends continuously around the
circumference of the tire and is sufficiently flexible so that when
impacted by an external object, such as a rock or raised ground
portion will bend inwardly and then outwardly thereby shaking off
the dirt or mud accumulating on the tire. In this manner, the tire
as well as the rim are kept relatively free of dirt and mud
accumulating thereon. Overhanging portion 71 jets outwardly from
the side wall 55 of the tire and can be positioned either on the
tire portion facing away from the vehicle or the tire portion
facing towards the vehicle. Likewise, overhanging portions can be
provided so as to jet out from both surfaces 54 and 55. In
addition, overhanging portion 71 may be manually moved by an
operator contacting portion 71 by hand or with another object or
with a particular object fastened to the vehicle.
[0033] The attachment of the tire to the rim by fasteners or bolts
60 (FIG. 10) extending through the flanges, also referred to as
tabs 35, and into the rim prevent the tire from rolling off the rim
as is the case in certain cases with the prior tire/rim
combinations. Further, the attachment of the tabs to the rim via
the fasteners allow for movement of the tire relative to the rim
resulting in the dirt/mud to be shaken off the tire and rim. The
attaching of the tire to the rim by fasteners not only allows for
flexibility but also provides a secure manner of mounting the tire
to the rim.
[0034] A conventional bearing 75 (FIG. 1) is located within the
mutually facing holes 41 (FIG. 6) of wheel discs 33 and 34. The
bearing facilitates the rotational motion of the wheel along axis
42 (FIG. 10) relative to the vehicle. A variety of methods are
utilized to mount the wheel to a vehicle, such as by extending a
fastening bolt through the central opening of the bearing to the
vehicle axle. In order to replace the bearing in the prior devices,
it is necessary to remove the tire from the rim. I have therefore
devised a bearing that is held in place by means of a C-clamp or
snap ring 76. Ring 76 (FIG. 10) is located at opening 41 of disc 34
and has an outer edge portion 77 that rides within a groove 78
formed on the interior surface 79 of hub 39 of disc 34. Groove 78
extends continuously around longitudinal axis 42 allowing the
opposite ends of the ring to be moved together thereby decreasing
the diameter of the ring with the ring then being slipped into
groove 78 with the opposite ends of the C-shaped ring then being
released thereby snapping the ring into the groove. The ring 76
abuts the end of the ring thereby limiting the movement of the
bearing in one direction along the longitudinal axis 42. In order
to exchange the bearing, the ring is removed from the hub, the
bearing is replaced by a new bearing and the ring is then
reinstalled into the groove 78.
[0035] Disc 33 is not provided with a groove 78. Instead, a
shoulder 88 is provided in the hub 39 of disc 33 that is located
against the end of the bearing limiting longitudinal movement of
the bearing along axis 42.
[0036] While the invention has been illustrated and described in
detail in the drawings and foregoing description, the same is to be
considered as illustrative and not restrictive in character, it
