Abstract

Pneumatic tyres are constructed with >=2 toroidal rubber tubes of similar or differing bore diam. and similar hoop diam. are positioned in a mould which permits a foamed rubber to be injected into the interstices between the tubes. The composite tubes/foam structure is enclosed by windings of rubberised cord in radial helical turns. The wound core is enclosed in a toroidal rubber sheath, opt. with a layer of reinforcing bandage between the core and sheath under the sub-tread and/or wheel rim faces. The sheathed core is then overmoulded or laminated to tread and rim face profiles. The internal tubes can be pressurised via either independent inlet valves or linked air supply system. Used for mfr. of hollow 'solid' tyres, ie. tyres without reinforced sidewalsl or rims and hence of simpler, cheaper construction than conventional crossply or radial ply reinforced tyres. The elastic bridges enhance the tyre stiffness against lateral distortion relative to easy radial distortion or compression, to provide a better combination of rolling comfort and roadholding when subject to lateral stresses during cornering.
