Definitions
- the invention comprises of a non-pneumatic wheel assembly, which is designed as an alternative for the conventional pneumatic tyre or solid tyre options currently available.
- pneumatic tyres A major issue with pneumatic tyres is that rubber is a poor conductor of heat and the flexible nature of a pneumatic tyre results in significant heat building up within the rubber walls, shoulders and tread. This heat is compounded in a tyre when carrying heavy loads, travelling at excessive speeds for a given load, excessive road temperatures, and insufficient inflation pressures. If this heat is generated at a faster rate than it can be dissipated, the heat accumulates to the point where it changes the chemical properties of the rubber, destroying its structural strength, causing the tyre to explode. This premature failure of tyres significantly adds to running costs, downtime, and at times, significant danger.
- Solid rubber tyres are used in limited applications, where pneumatic tyres are frequently punctured. Foam filling of pneumatic tyres (instead of air) alleviates this problem where small punctures occur and the tyre structure though perforated, remains intact. However foam filling is very heavy, and it will not help in situations where the tyre structure is easily torn; in these situations solid tyres are currently the only option. Solid tyres are not popular, however, as they offer very little shock absorbance, and the vibrations travelling through the vehicle greatly reduces the ride comfort, and significantly increases the wear and tear of the vehicle.
- Pneumatic tyres clearly provide a significant role in vehicle suspension, and it is ideal if this benefit can be maintained in any alternative wheel, which is non-pneumatic, thus alleviating the need to add extra suspension by another means.
- a previous example of a non-pneumatic wheel has a relatively stiff but flexible rubber outer rim connected to the inner hub through a series of web spokes which carry very little compressive load. In this case the load is carried by the spokes acting in tension, with the shape of the wheel maintained by the stiffness of the outer rim.
- This design is not expected to be suitable as a substitute for very large tyres as the thick flexible rubber outer rim is likely to have similar heat-retention properties to that of current tyres.
- Non pneumatic tyres which include US Patent 4,945,962 which refers to a tyre formed from a unitary honeycomb structure bounded by integrally moulded outer and inner hoops and a single side web member. Reference may also be made to US Patents 4,934,425 and US Patent 4,832,098 which each refer to a non pneumatic tyre having a polyester polyol urethane elastomeric body with a plurality of angular radial ribs interconnected by webbing.
- US Patent 6,698,480 refers to a non pneumatic tyre having a hub and rim assembly interconnected by a plurality of radially oriented shock absorbing spokes each of which comprise a piston and tube assembly functioning as a clamping mechanism.
- US Patent 6,374,887 describes a non pneumatic tyre formed from rubber or elastomeric material having an outer crown or hoop having sidewalls joining the crown and terminating in circumferentially extending beads adapted to be received in a wheel rim. A plurality of circumferentially spaced leaf springs are, at their ends resiliently embedded in the respectively beads.
- US Patent 5,139,066 concerns a non pneumatic tyre having an outer peripheral portion and an inner peripheral portion interconnected by a circumferential web.
- US Patent 4,784,201 refers to a non pneumatic tyre formed from resilient elastomeric material having circumferentially spaced apart ribs interconnecting an outer cylindrical member and an inner cylindrical member.
- US Patent 3,779,616 which comprises a rigid circular inner structural component which is surrounded by a continuous flexible track having a plurality of pad elements joined together continuously in edge to edge relationship by a plurality of hinges each of which is interposed between adjacent edges of the pad elements.
- a plurality of arcuate members each having a first end pivotally connected to one of the hinges and a second end pivotally connected to another of the hinges.
- Each arcuate member span at least two hinges and more suitably three hinges.
- Each arcuate member overlap each other and there is also provided a plurality of crank elements each of which is pivotally connected at one end to one of the arcuate members by a first pivot joint and at another end to the inner circular structural component by a second pivot joint.
- a lubrication system is also provided for the crank elements so as to facilitate lubrication of the first and second pivot joints.
- US Patent Application Publication No. 2004/0159385 which describes a non pneumatic tyre having a ground contacting tread position, a reinforced annular band disposed radially inwardly of the tread portion and a plurality of web spokes extending transversely across and radially inwardly from the reinforced annular band and anchored in a hub.
- the reinforced annular band comprises an elastomeric shear layer, a first membrane adhered to the radial inward extent of the elastomeric shear layer and a second membrane adhered to the radially outward extent of the shear layer.
- Each of the membranes has a longitudinal tensible modulus of the shear layer so that when under load the ground contacting position of the tyre deforms to a flat contact region through shear strain in the shear layer while maintaining constant the length of the membranes, the web spokes transmitting load forces between the annular and the hub through tension in the web spokes not connected to the ground contacting portion of the tyre.
- Publication 2004/0159385 would need a very thick outer hoop which has the deficiency of generating excess heat which would cause damage to the tyre.
- the invention therefore provides a non-pneumatic wheel assembly which has
- a compartment located between the outer rim assembly and the inner hub connection member which has a plurality of spring elements wherein at least some of the spring elements are attached to the outer rim assembly and/or the inner hub connection member characterised in that the spring elements are oriented in opposing or counteracting orientations.
- the outer rim assembly may comprise a continuous annular member of solid or flexible material covered in rubber or other suitable elastomeric material.
- the outer rim assembly instead of forming a continuous annular member may comprise a plurality of traction or rim elements suitably in the form of plates pivotally or hingedly connected to each other as shown in the preferred embodiments herein.
- Each of these traction elements may have an outer rubber tread element attached thereto so that the outer rim assembly comprises a plurality of traction elements covered in tread elements thereby providing a multiplicity of pads all hingedly connected to each other. This is useful when the non pneumatic wheel assembly of the invention is used as a substitute for a conventional pneumatic tyre.
- the plurality of traction elements may be covered by an annular member of solid rubber. This is useful when the non pneumatic wheel assembly of the invention is to be used as a substitute for a solid wheel and this also applies when the outer rim assembly comprises a continuous annular member covered with an annular rubber tread.
- the non pneumatic wheel assembly of the invention may also be used on machinery using tracks, replacing the conventional solid wheels that support the tracks thereby adding suspension.
- the outer rim assembly may be covered with an annular rubber sheath as a friction grip drive on an internal surface of the tracks.
- the outer rim assembly may have elevated teeth to provide a positive drive for tracks with central drive sprocket apertures.
- the non pneumatic wheel assembly may be mounted on large mining trucks, loaders, large underground forklifts, rubber tracked agricultural tractors and steel tracked excavators and bull- dozers.
- the inner vehicle hub connection member is suitably a solid annular member which has an inwardly extending flange having a plurality of attachment apertures for attachment to a hub of a vehicle in well known conventional manner.
- the inner hub connection member on an internal surface thereof may have a plurality of races for supporting the spring elements.
- one race may support an array of spring elements which are preferably curved or arcuate and all oriented in a similar direction.
- An adjacent race may support another array of spring elements which are preferably curved or arcuate and which extend in an opposing or .counteracting orientation.
- races are not an essential feature and thus the spring elements may be directly attached to an internal surface of the inner hub connection member.
- the races are useful for preloading the spring elements and providing the means to easily adjust this loading thereafter.
- inner attachment means for the arcuate spring elements may comprise a plurality of attachment lugs or pinning lugs for attachment of a proximal end of an adjacent spring element to the inner hub connection member and more suitably to an adjoining race.
- inner attachment means may facilitate rotation of each of the spring elements about a common axis of each pair of attachment lugs.
- outer attachment means for the two different arrays of curved spring elements as described above and in one form such outer attachment means may have pairs of spaced lugs as described above for the inner attachment means which pairs of spaced lugs extend away from an internal surface of the outer rim assembly.
- damping elements may comprise hydraulic ram assemblies, gas struts or members having a suitably inwardly directed bias ensuring that the wheel assembly has a circular shape.
- a damping element is referred to in US Patent 6,698,480 which refers to shock absorbing spokes located between an outer rim assembly and an inner hub member.
- damping elements may be attached to a central race located on an internal surface of the inner hub connection member and by suitable attachment means which may comprise a single attachment lug or pair of opposed attachment lugs where an adjacent end of a respective clamping element may be attached thereto by a suitable fastener.
- the spring elements as discussed above may be of sufficient width to support the wheel assembly of the invention in a single plane with both arrays of opposing spring elements located in a single plane. However more preferably each of the arrays of spring elements are located in different planes.
- Each spring element of each array may be similar in shape and rotation of the supporting race enables a set force or loading to be applied to each spring element. This enables the load carrying capacity of each spring element to be fine tuned as well as facilitating assembly of the wheel assembly by initially providing the spring elements in a relaxed state prior to forcing them into a compressed state in accordance with design characteristics of the wheel assembly.
- the weight of the vehicle is supported primarily by those spring elements which are located between the inner hub connection member and the ground placed under compression.
- the outer rim assembly is a solid annular member the spring elements in an upper half of the wheel assembly are in tension, sharing the load with the lower spring elements which are in compression.
- one or more intermediate rings between the inner hub connection member and the outer rim assembly.
- an inner array of spring members extending between the inner hub connection member and the intermediate ring.
- an outer array of spring elements extending between the intermediate ring and the outer rim assembly. The function of this form of the invention is to provide a more flexible outer position compared to the inner portion which maintaining load carrying and torque delivering characteristics.

- the inner mounting plate 11 A may also be provided with pockets 125 on each side of the outer surface 126 of mounting plate 11 and central pockets 127 similar to pockets 122 referred to above.
- the outer rim assembly 26A may be made from strong flexible material such as composite fibre products.
- E-glass which is a low alkali borosilicate glass reinforced epoxy composite.

- the outer rim assembly 26A being formed from flexible material may also be flattened when it contacts the road or support surface as shown at 128. It is stressed that this only applies in use and that the rim 26A will be circular otherwise.
- a detail "B" of pockets 120 is shown in FIGS 20-21 where springs 21 in the form of straps will engage with pockets 120 as shown. This also applies to pockets 122, 125 and 127.
- Springs 21 as shown in FIGS 19-20 may be strap like in shape as shown in FIG 19 or be provided with a neck or waisted portion 129.
- springs 21 , 22 or 22A may be formed from different flexible material to the outer rim assembly 26A.
- mounting plate 11A may also be formed from flexible material. It is considered that folding of straps 21 , 22 and 22A at neck 129 may take place thereby providing a hinging effect. This hinging effect may also be achieved by using different flexible materials for the pockets as well as the springs.
- the springs 21 , 22 and 22A may be attached to the outer rim assembly 26A and the inner mounting plate 11 by fitting into pockets, either by using a friction fit or secured by other means which may be mechanical.
- the springs may be of uniform or non-uniform thickness over their length.
- the springs may be pinned or may be necked to effectively produce a hinge without the need for conventional pinning.
- the springs may be manufactured using a single material or may be a composite of different materials. This may be particularly useful in creating effective 'hinges' by using a different thickness of material or a combination of different materials (eg just a short length of really flexible material), rather than using a regular pinning mechanism.
- the outer rim assembly 26A may be constructed of a continuous (or non-continuous) flexible material to permit deflection under load.
- non-pneumatic tyre of the invention has substantial advantages over the prior art discussed above because of the provision of counteracting springs 21 , 22 and 22A which provide the necessary strength for use as a non pneumatic wheel.
