Description
NON-PNEUMATIC COMPOSITE INTEGRATED TYRE AND WHEEL AND METHOD OF FABRICATION THEREOF
Field of the Invention
The present invention generally relates to a tyre and wheel construction, and more particularly to a non-pneumatic composite integrated tyre and wheel construction, fabricated from composite layers incorporating interconnected reinforcing internal frame elements. Whilst the present invention is applicable to fabrication of motor vehicle wheels, it is to be appreciated that it is not limited to that application.
Background of the Invention The following discussion of the background to the present invention is intended to facilitate an understanding of the invention. However, it should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge as at the priority date of the application.
Historically, wheels with separate pneumatic tyres have been utilised for load carrying, road shock absorption and force transmission. However, it is common for a flat tyre to occur as it deflates as a result of normal wear-and- tear, a leak, or other damage. It has been found that a pneumatic tyre which has lost sufficient pressure will impair the stability of the vehicle and may damage the wheel and the vehicle and become a major safety issue.
Non-pneumatic tyres have been developed without the requirement of containing pressurised air to overcome the disadvantage of the escape of air contained under pressure from pneumatic tyres. However, non-pneumatic tyres still have the known associated disadvantages of having to be attached to and detached from a wheel. Further, when being detached from a standard multi- piece rim wheel, will also pose a danger to the person changing the tyre as evidenced by the fatality in 2007 (New York State Department of Health - Fatality Assessment and Control Evaluation, Case Report 07NY137 www.nvhealth.gov/nysdoh/face/face.htm).
Construction of composite wheels has developed to address light- weighting of wheels to improve vehicle performance. However there still exist the issues of hysteresis as well as the known associated disadvantages of having to attach and detach the tyre from the wheel.
Thus, attempts have been made to overcome these issues by the construction of a non-pneumatic composite integrated tyre and wheel; however these previous attempts have their own disadvantages.
Prior Art
The inventors of the present invention have utilised their investigations which support the principles that generally, non-pneumatic wheels are restricted to speed limitations due to heat accumulation in the wheel known as hysteresis. Further, generally deformation of reinforcing elements within an integrated non- pneumatic tyre and wheel occurs as they are not effective and/or efficient at simultaneously being able to opposing forces from all directions including the capacity to resist centrifugal as well as centripetal forces during rotation.
Known methods of non-pneumatic composite integrated tyre and wheel formation include the following patents:
· CA1227729 A1
• RU2007299C1
• US6170544 B1
• US7523773 B2
• US20040069385 A1
· WO2006116807 A1
However, the prior art have at least one of the following disadvantages:
• complex construction of non-pneumatic composite integrated tyre and wheel;
• radius of curvature of internal radial reinforcing elements not optimised resulting in early onset of hysteresis;
• geometric form of the spoke aspects of the non-pneumatic composite integrated tyre and wheel not optimised for cooling resulting in early onset of hysteresis;
• requires additional means to adhere the internal reinforcing elements to the hub aspect and/or tread aspect of the non-pneumatic composite integrated tyre and wheel;
• requires additional means to attach the non-pneumatic composite integrated tyre and wheel to the axle of a vehicle.
It would therefore be desirable to provide an alternative non-pneumatic composite integrated tyre and wheel that overcomes some or all of the drawbacks of the prior art.
Objectives of the Present Invention
• simplify construction to enable an efficient and cost effective fabrication process;
• optimise the radius of curvature of internal radial reinforcing elements to prevent the early onset of hysteresis;
• optimise the geometric form of the spoke aspects of the non-pneumatic composite integrated tyre and wheel for cooling to further prevent the early onset of hysteresis;
• incorporate simultaneous adherence of the internal reinforcing elements to the hub aspect and tread aspect of the non-pneumatic composite integrated tyre and wheel as part of the fabrication process to ensure a more durable construction;
• incorporate into the design of the non-pneumatic composite integrated tyre and wheel an inclusive means via internal connective elements for attachment of the non-pneumatic composite integrated tyre and wheel to the axle of a vehicle, which provides a means for stabilisation along the axis of rotation via a secured assembly.

Description of the Non-Pneumatic Composite Integrated Tyre and Wheel with reference to the Drawings
The present invention provides a non-pneumatic composite integrated tyre and wheel (1) as a monolithic composite material form fabricated from layers (19, 35, 37) prepared from a devulcanised and/or activated rubber mass, such as for example from fibre impregnated devulcanised and/or activated rubber powders obtained from a tyre recycling process, the said layers (19, 35, 37) having been laid in a specific order in coordination with the placement of pre-tensioned reinforcing internal frame elements (7, 8, 9).
The said non-pneumatic composite integrated tyre and wheel (1) incorporates internal connective elements (2) supporting pre-tensioned radial reinforcing internal frame elements (7) which concurrently support pre- tensioned circumferential reinforcing internal frame elements (9, 22), the said interconnected pre-tensioned reinforcing internal frame elements (7, 8, 9, 22) thus being capable of simultaneously opposing forces from all directions including the capacity to resist centrifugal as well as centripetal forces during rotation.
The said connective elements (2) additionally provide a means for stabilisation of the said non-pneumatic composite integrated tyre and wheel (1) along its axis of rotation via a secured assembly. The said connective elements (2) additionally act as a shock-absorption mechanism.
The said pre-tensioned radial reinforcing internal frame elements (7) have an optimal radius of curvature at the interface with the said connective elements (2) to minimise fatigue and prevent disintegration of the said radial reinforcing internal frame elements (7) and their surrounding composite materials (3, 4, 13, 16) from hysteresis whilst still optimising effective load bearing capacity.
The said non-pneumatic composite integrated tyre and wheel of the invention (1) has geometrically aligned and coordinated apertures (5, 10, 12c, 12d) and/or false holes (12a, 12b) to simultaneously enable damping and load distribution by the formed monolithic hub (3) and spoke aspects (4) and their interconnections formed by the barriers (16) between the said apertures (5, 10, 12c, 12d) and/or false holes (12a, 12b), whereby the resultant geometric form of the said spoke aspects (4) is both internally reinforced by the radial reinforcing internal frame elements (7) as well as supported laterally by the interconnecting barriers (16) between the said apertures (5, 10, 12c, 12d) and/or false holes (12a, 12b) to reduce the unsupported length of the spoke aspects (4), which allows for optimal flexibility in correlation with the optimal radius of curvature of the pre-tensioned radial reinforcing internal frame elements (7) to further prevent disintegration and hysteresis.
The surrounding construct walls of the said apertures (5, 10, 12c, 12d) and/or false holes (12a, 12b) have a corrugated surface (18) enabling intensified dynamic ventilation of the said non-pneumatic composite integrated tyre and wheel (1 ) to prevent disintegration and hysteresis.
The non-pneumatic composite integrated tyre and wheel (1) can also contain weighted pre-tensioned circumferential internal frame elements (22) positioned at the periphery of the central-line fabrication layer (37) to provide a flywheel-like energy storage mechanism as well as additional circumferential reinforcement.
All the said fabrication layers (19, 35, 37) that are composed of devulcanised and/or activated rubber mass that can be impregnated with interdispersed, linearly aligned and/or meshed reinforcing materials as required.
The said pre-tensioned radial (7, 8) and circumferential (9, 22) reinforcing internal frame elements are composed of a tension allowing single or multiple
layered material with elasticity restoring properties such as for example but not limited to carbon fibre or alloy.
The central aspect of the hub (3) of the said non-pneumatic composite integrated tyre and wheel (1) can have a central aperture (17) for the inclusion of brake and/or suspension mechanisms as required.
The side aspects of the hub (3) of the said non-pneumatic composite integrated tyre and wheel (1) can have a means for fixation of flanges (14) that incorporate inwardly sloping finger-like protrusions for entry into the apertures (5, 12c) and/or false holes (12a) between the spoke aspects (4) of the said non- pneumatic composite integrated tyre and wheel (1) in order to provide additional tension for the said spoke aspects (4).
The side aspects of the said non-pneumatic composite integrated tyre and wheel (1 ) can have fixation elements for the attachment of a hub cap (23). Description of the Method of Fabrication of the Non-Pneumatic Composite Integrated Tyre and Wheel with reference to the Drawings
In the fabrication process of the said non-pneumatic composite integrated tyre and wheel (1) the fabrication layers (19, 35, 37) which have been prepared from a devulcanised and/or activated mass, such as for example from fibre impregnated devulcanised and/or activated rubber powders obtained from a tyre recycling process, the said fabrication layers (19, 35, 37) have also been further impregnated with interdispersed, linearly aligned and/or meshed reinforcing materials as required, are laid down in a specific order that enables coordination with the placement of tension allowing reinforcing internal frame elements (7, 8, 9, 22) over a support (28) within a manufacturing device.
The said laying order of the fabrication layers (19, 35, 37) is alternated with the corresponding laying order of an interconnecting resin, such as for example epoxy resin, or alternatively the fabrication layers (19, 35, 37) are coated with the said resin prior to being laid.
The said laying order of the fabrication layers (19, 35, 37) is thus coordinated with the positioning and tensioning of the radial reinforcing internal frame elements (7) which are looped over or threaded around supported connective elements (2). The said radial reinforcing internal frame elements (7)
are thus aligned together with the central-line fabrication layer (37) during the laying process. The said central-line fabrication layer (37) incorporates grooves and/or channels in its upper, middle and lower peripheral aspects as required, allowing for the placement of the circumferential reinforcing internal frame - elements (9, 22) in its periphery and thus enabling interconnection of the said circumferential reinforcing internal frame elements (9, 22) with the radial reinforcing internal frame elements (7, 8) that are aligned together with the central-line fabrication layer (37).
A limiting circular guard (27) with an incorporated tread pattern on its internal face is placed into a circumferential groove (36) on the peripheral outer section of the said support (28) of a manufacturing device. An enclosing fabrication layer (19) is added within the limits of the limiting circular guard (27), where the said enclosing fabrication layer (19) can be made up from recycled tyre tread.
The fabrication process utilises means such as pressure and heat, as well as additive curing agents as necessary, to form the said non-pneumatic composite integrated tyre and wheel (1) with pre-tensioned reinforcing internal frame elements (7, 8, 9, 22), the said fabrication process enabling the reinforcing internal frame elements (7, 8, 9, 22) to become tensioned and themselves be reinforced by being encased in the layered masses (35, 37) impregnated with interdispersed, linearly aligned and/or meshed reinforcing materials, as required.
The manufacturing device for the fabrication process can be any known device that can utilise pressure and heat to produce the necessary load rating and tread wear requirements for the non-pneumatic composite integrated tyre and wheel (1), such as for example but not limited to a moulding device such as a compression mould, or an additive manufacturing device such as for fused depositioning, or flow forming devices, or the like.
