The present subject matter relates generally to agricultural machinery tires. In particular, the subject matter relates to a new type of warning indication system.
A tire is a temporary ring shaped covering that fits around the rim of a wheel of a vehicle. Tires are composed mainly of synthetic rubber, natural rubber, fabric, high tensile steel wire along with other compound chemicals. A tire consists of a tread and a body, where the tread provides traction and the body provides support. Nowadays, tires are pneumatic inflatable structures including a doughnut shaped body of cords and wires encased in rubber to form an inflatable cushion. The main purpose of a tire is to provide traction between the vehicle and the road surface, reduce road shock for the vehicle and its occupants, and to protect the wheel rim. Tires are used on numerous types of vehicles including bicycles, motorbikes, cares, lorries, farm vehicles, earthmovers, plant machinery, and aircraft.
In agriculture, tires are used on farm vehicles usually tractors, trailers, specialist harvesters, and other types of machinery. Due to the size of these vehicles and the different types of terrain, these tires are much larger and wider than conventional car tires. These tires have very deep widely spaced lugs to allow the tire to grip soil easily. Where ground conditions are very poor and where soil compaction is a concern, wide, high floatation tires are used that have large footprints and low inflation pressures.
Agriculture vehicles often travel on public roads, particularly tractors with a trailer or another implement behind it. These vehicles are awkward and bulky on roads, especially on narrow roads in the countryside, which they use more often than larger roads, due to their proximity to agricultural farms. When other vehicles meet agricultural vehicles on these roads it is difficult to pass by.
This problem is more pronounced and significant at night when visibility on unlit public roads in the countryside is poor. When meeting large agricultural vehicles at night on these roads it is difficult to ascertain their width until in very close proximity which poses a traffic hazard. The reason for this is because the existing lighting arrangement on agricultural vehicles does not properly highlight their actual size and width. Agricultural vehicles with especially large tires and older agricultural vehicles with very poor lighting arrangements are even more dangerous.
Consequently, there exists a need for a tire design for agricultural vehicles that highlights actual size and width of these vehicles, which will allow them to travel more safely on public roads at nighttime.
The present disclosure provides a reflective tire marking. Various examples of the marking systems are provided herein.
Specifically, the present disclosure provides a reflective tire marking comprising an illuminous color, reflective, rubber mold insert and a hole in the outer section of each lug of a tire of an agricultural vehicle into which the said illuminous color, reflective rubber mold insert will be securely fit.
In an embodiment, the reflective tire marking system, for use as a warning indication to highlight the width of large vehicles, includes a reflective tire marking located within a tire lug of a tire, wherein the reflective tire marking is made of a reflective rubber.
In an example, the reflective tire marking is securely fit by pressure into the at least one lug of the agricultural tire. In another example, the reflective tire marking may be located within a majority of the tire lugs on a tire. Further, the reflective tire marking may be inserted into a hole within the at least one tire lug. In an example, the reflective tire marking may be cylindrical.
The tire lug may extend toward an outer edge of tire, and wherein the reflective tire marking is located within a portion of the tire lug that approaches the outer edge of the tire. Alternatively, or in addition to, the tire lug may include an outer edge portion, wherein the outer edge portion approaches an outer edge of a tire, wherein the reflective tire marking is located within the outer edge portion of the tire lug.
In one embodiment, the reflective tire marking is a rubber mold insert in a reflective illuminous color that is securely pressure fit within the outer section of each lug of the agricultural tire.
In an example, a cylindrical hole of approximately 40 millimeters (mm) in depth and radius of approximately 15 mm is bored in each lug grip of an agricultural vehicles tire, into which the reflective tire marking is pressure fit to form a permanent reflective warning indicator.
The present disclosure also provides a method of forming a tire comprising pressurize molding rubber around at least a portion one reflective tire marking, wherein the reflective tire marking is made of a reflective rubber, and wherein the reflective tire marking is positioned in a portion of a tire lug that approaches an outer edge of the tire.
An advantage of this invention is that the reflective tire marking allows for light to be reflected from the agricultural tires, highlighting the actual size, particularly the width, of large agricultural vehicles to oncoming traffic from both directions. This innovative reflective marking acts as a very effective safety design feature for all agricultural vehicles, creating a safer transport network for road users.
Additional objects, advantages and novel features of the examples are set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following description and the accompanying drawings or may be learned by production or operation of the examples. The objects and advantages of the concepts may be realized and attained by means of the methodologies, instrumentalities and combinations particularly pointed out in the appended claims.
The drawing figures depict one or more implementations in accord with the present concepts, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.
For example, the tire lug 16 may extend toward an outer edge 18 of a tire, as shown in
Alternatively, the reflective tire marking 14 may be attached, inserted, or otherwise located anywhere along the face of the tire such that oncoming traffic is able to determine the width of the vehicle. For example, the reflective tire marking 14 may be inserted into the lug voids 22, wherein the lug voids 22 are the valleys in between the tire lugs 16. The reflective tire marking 14 may be located in a portion of the lug void 22 that approaches the outer edge 18 of the tire.
The reflective tire marking 14 is typically an illuminous color, reflective, rubber mold insert, as shown in
The reflective tire marking 14 may be made of any reflective material such that the reflective tire marking 14 reflects oncoming light. For example, the reflective tire marking 14 may be made of reflective plastic, rubber, metal, or combinations thereof, among others. Preferably, the reflective tire marking 14 is made of a reflective rubber material. Even more preferably, the reflective tire marking 14 has wear characteristics that are similar to the remainder of the tire such that the reflective tire markings 14 do not wear unevenly with the tire lugs 16.
The reflective tire marking 14 may be fit into the tire lug 16 by various mechanisms. For example, the reflective tire marking 14 may be secured within the tire lug 16 by a pressure fit, adhesives, screws, nails, or any other fastening means. In one example, a hole may be bored in the outer edge portion 20 of each tire lug 16 of the tire 12 into which the reflective tire marking 14 is inserted. Preferably, as shown in
For example, a cylindrical hole of approximately 40 mm in depth and radius of approximately 15 mm may be bored in each tire lug 16 of an agricultural vehicles tire, into which the reflective tire marking is inserted by utilizing hydraulic pressure to form a permanent reflective warning indicator. Alternatively, the tire 12 may be manufactured such that the reflective tire marking 14 may be inserted into the tire 12 during the pressurized molding stage of the tire manufacturing process.
The present disclosure also provides for a method of modifying vehicle tires. The method may include boring a hole into the outer edge portion 20 of at least one tire lug 16 of the tire 12, and securing the reflective tire marking 14 within the hole. The hole may be between, and including, 10 mm to 50 mm in depth, for example, 30 mm to 40 mm. The radius of the hole may be between, and including, 10 mm and 50 mm, for example, between 20 mm and 30 mm.
As an alternative to modifying existing vehicle tires, the present disclosure also provides a method of manufacturing a vehicle tire 12 comprising a reflective tire marking 14. For example, the manufacturing process may include forming tire lugs 16 containing the reflective tire marking 14. For example, the tire 12 may be manufactured such that the reflective tire marking 14 may be inserted into the tire 12 during the pressurized molding stage of the tire manufacturing process.
It should be noted that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages.
