Definitions

  • THIS INVENTION concerns a novel form of vehicle wheel, and a method of fabricating same particularly, though not exclusively, for racing vehicles.
  • wheels are produced either from steel or an alloy, and it is an object of the present invention to provide a wheel which is lighter in weight and has greater strength than most conventionally manufactured wheels. The consequent reduction in unsprung weight of the vehicle improves its racing performance.
  • a method of fabricating a vehicle wheel comprises the steps of providing a pattern consisting of one or more parts whose surface configuration resembles the wheel to be produced; producing from said pattern surface, by a moulding process, at least two mould parts representing inner and outer profiles of the wheel to be produced; moulding to said mould parts inner and outer wheel profiles respectively; and combining said wheel profiles to form the finished wheel.
  • said pattern is provided in two or more parts; each said mould part is provided in two or more sections which are attached together prior to moulding the wheel profiles; at least one adaptor ring is placed in contact with at least one of said mould parts to form a hub profile; and a core of structural material is formed to opposed surfaces of the two wheel profiles and sandwiched between the latter in the completed wheel.
  • the completed wheel is preferably surrounded by a moulded rim wrap in which tyre bead profiles are incorporated.
  • Fig. 1 is a schematic cross-sectional view of a pattern formed as a first part of the fabricating method according to the invention
  • Figs. 2a and 2b illustrate tools or moulds produced from said pattern
  • Fig. 3 is an exploded view of a multi-part pattern
  • Fig. 4 is an exploded view of multi-part tools or moulds fabricated therefrom;
  • Figs. 5a and 5b illustrate said multi-part tools or moulds assembled to form inner and outer mould profiles respectively;
  • Fig. 6 is an enlarged view of the assembly of a hub sleeve or adaptor for the inner profile of Fig. 5a;
  • Fig. 7 is an enlarged view of an assembly means to provide a wheel centre profile to accept a hub sleeve or adaptor for an outer wheel profile;.
  • Fig. 8 is a cross-sectional view of a tool or mould assembled in readiness for moulding an inner wheel profile
  • Fig. 9 is a similar view of a tool or mould assembled in readiness for moulding of an outer wheel profile
  • Fig. 10 is an exploded view showing inner and outer wheel profiles produced by and lying between inner and outer moulds, to illustrate removal of the wheel profiles from their moulds;
  • Fig. 1 1 is an exploded view of inner and outer wheel profiles with a structural core therebetween;
  • Fig. 12 is a cross-sectional view of a wheel in its final stages of production whereat a rim wrap is provided.
  • Fig. 13 is a schematic cross sectioned view of part of a central hub region according to an alternative embodiment
  • Fig. 14 is a front view of the arrangement illustrated in Fig. 13; and Fig. 15 is a view taken on line A-A of Fig. 14.
  • a pattern 10 is made initially from a suitable material such as hardwood which is machined or turned out of solid or multiple layers of the wood to form the shape illustrated.
  • a one-piece pattern is provided having vent holes 11 machined at various spaced positions around the axis.
  • the working surface of the pattern 10 is prepared with a release agent and, optimally, a gel coat is laid over the surface and allowed to become partially dry.
  • a layer of pre-impregnated glass fibre or carbon fibre is then laid up or draped over the surface of the pattern and this is followed by three layers of pre-impregnated carbon fibre. Finally, a release film and a cloth bleed layer are applied and the whole assembly is placed in a sealed bag whereupon a vacuum forming technique is applied at a pressure of, for example, one bar and the assembly is allowed to part-cure.
  • Figs. 2a and 2b illustrate the moulds produced, and these are provided with vent hole surfaces 14 and 15 in a similar manner.
  • the process described previously may be carried out to produce mould sections 16 from separate pattern parts 17, the sections 16 then being bolted or otherwise attached together as illustrated at 18 in Figs. 5a and 5b to form the moulds.
  • the mould parts may have mating stepped recesses formed by incorporating blanking plates or other protrusions on the pattern parts.
  • an alloy carbon fibre hub sleeve 19, or a removable adaptor of similar shape is placed on one of the mould profiles, in this example the inner profile 12 and this is carried out as illustrated in Fig. 6 where a machined alloy peg 20 is placed in the centre line receptor 21 of the mould (see Fig. 2a), and this is followed by a concentric sleeve 22 which has an outwardly tapering flange 23on its inner end.
  • the hub sleeve 19, is concentrically placed over the sleeve 22 and peg 20 as illustrated.
  • a similar alloy peg 24 is placed in the mould receptor 25 (see Fig. 2b) and this is followed by a concentric sleeve 26 which has an outer end flange 27.
  • Figs. 8 and 9 illustrate respectively completed moulds for inner and outer wheel profiles.
  • the hub sleeve 19 or adaptor mounted on its peg 20 and sleeve 22 against the outer surface of the mould 12 and there can also be seen removable lugs 28 which will provide a moulding surface for the vent holes in the finished wheel.
  • These lugs include outer sleeves 29 which are subsequently removable for a purpose to be described.
  • an additional ring 30 which is in two or more annular sections to provide a "hollowed" shape for the wheel in the region which will be adjacent the brake disc and calliper in use. This is to enable the wall of the finished wheel to be located as far away as possible from the heat-generating brake mechanism.
  • the inner and outer wheel profiles are then fabricated by laying up or draping several layers of carbon fibre over each of the mould surfaces. After several successive layers have been applied a release film and bleed layer cloth can be applied and the whole assembly for each profile is placed in a vacuum bag, formed and part-cured in an oven in much the same manner as was adopted when fabricating the mould parts. This procedure may be repeated several times, if necessary, as layers of carbon fibre material are built up to produce the wheel profiles. Once fully cured the laminated wheel profiles are removed from their respective moulds, and all additional mould parts, such as ring 30, are removed, leaving inner and outer wheel profiles 31 and 32 as illustrated in Fig. 10. The inner wheel profile 31 has been formed with the hub sleeve 19 in situ, whilst the outer wheel profile 32 has been formed with a receptor collar 33 to receive the corresponding central region of the inner ' profile 31.
  • the inner and outer wheel profiles 31 and 32 may be produced each with its own internal core of a honeycombed aramid fibre paper or alloy to enhance the structural characteristics and performance of the finished wheel. This can be done by bonding the honeycombed material to one surface of half of the layers of carbon fibre material once they are fully cured.
  • the honeycombed core may be held in place by any appropriate method such as a vacuum bag and placed in an oven and cured.
  • the remaining layers of carbon fibre would then be applied directly over the honeycombed core and the process repeated until the required thickness is achieved.
  • a glue film would be applied before the additional carbon fibre layers.
  • a thin profile of honeycombed material is sandwiched between carbon fibre to increase structural integrity commensurate with minimal weight.
  • FIG. 11 there are illustrated the inner and outer wheel profiles 31 and 32 respectively and a structural core element 38 which is to be sandwiched between them.
  • This core element is produced from a structural foam or honeycombed aramid fibre paper or an alloy and may be formed according to the following method steps.
  • the inner and outer wheel profiles 31 and 32 are placed together to define a cavity therebetween.
  • a closing rim (not shown) is placed around the circumference of the cavity and two apertures are pierced in the closing rim to permit the injection of an expanding resin which is then allowed to set.
  • the expanded resin core shape is available to serve as a buck for producing the final core element 38 from materials referred to previously. Once this is machined to shape, it is placed in between the inner and outer profiles 31 and 32 which are then brought together, and the entire assembly is bonded to form a single structure, as shown in Fig. 12.
  • An outer profile hub sleeve or adaptor 35 is bonded to the outer surface of the outer profile 32 in the hub region and to the complementary surfaces of the inner hub sleeve or adaptor 19.
  • Sleeve 35 defines a ring of apertures 35a around its peripheral region to minimise its weight. Apertures to accept a series of drive pegs (not shown) which extend outwardly from the upright assembly of the vehicle hub are provided in the hub sleeve 19, and as illustrated by the dotted lines 39, the pegs are accommodated in blind apertures 40 provided in the wheel structure.
  • the wheel is completed by applying successive layers of pre-impregnated carbon fibre as a rim wrap 36 around the peripheral surface of the assembly. This is shown for the purposes of illustration in Fig. 12 as being spaced radially therefrom.
  • the rim wrap 36 is applied by successive vacuum forming steps as described previously in relation to other parts of the assembly.
  • the central region of the wheel may comprise a hub section 41 which, like most other parts of the structure, may be pre- moulded from carbon fibre, a number of radially extending reinforcing spokes 42, and, interposed between the spokes 42, a number of vent hole assemblies 43.
  • the spokes 42 and assemblies 43 may be produced by laying up and curing carbon fibre material.
  • each spoke assembly 42 comprises an inner core 44 of honeycombed aramid fibre paper or alloy having laid up on each side thereof a carbon fibre skin 45.
  • the honeycombed core 44 is of the kind having considerable compressive strength in one direction, transverse to the radius of the wheel.
  • Each spoke 42 is thus formed with an I-shaped cross section the flanges of which can abut or overlap the opposing faces of the adjacent vent hole assemblies 43.
  • the hub and spoke section 41, 42 is assembled in a jigging mould with vent hole assemblies 43.
  • These components are bonded together with a high strength adhesive and are adapted to receive the inner and outer wheel profiles in a form generally similar to those illustrated in Fig. 1 1 but with the omission of vent hole parts 34 and 35 and hub parts 19 and 33.
  • the fabrication system described in relation to Figs. 13 to 15 is a substitute for the vent hole and core assembly of the previous embodiment and may be considered a preferable manufacturing technique.
  • the number of radial spokes 42 and of the vent hole assemblies 43 may be selected according to user requirements and to ensure minimum weight commensurate with adequate structural ability.
  • the wheel is completed with a rim wrap and tyre bead seats laid up upon its periphery, and the hub will receive an adaptor or sleeve similar to that illustrated at 35 in Fig. 12 but with a plain annular insert to be received within the hub section 41.
  • a wheel made in accordance with the invention as described above is light in weight but structurally sound.
  • the patterns and tools which are variable in configuration to some extent are however substantially standard, whilst the hub sleeves or adaptors 19 and 35 may be provided to suit the particular axle assembly of the end user.
  • a wheel produced in accordance with the invention substantially avoids the use of cast or spun alloy components and consists of an integrated structure from composite materials which may be used in any combination to provide optimum weight and performance characteristics. These materials make up substantially the entire wheel and may be adapted also for the hub sleeves which incorporate the main load-bearing faces of the wheel in its hub region.
