Improvements to pneumatic tires

Multichamber pneumatic tyre with supply and discharge ducts - to all chambers, and limited communication for pressure balancing

A multi-chamber pneumatic tyre has all chambers supplied through individual non-return valves from an air supply duct running circumferentially through the tyre, all the chambers being also connected by individual non-return valves to a common, circumferential discharge air duct; both these ducts are connected to a common principal valve used for inflating and deflating the tyre. This principal valve comprises a valve chamber connected by passages to the air supply duct and air discharge duct resp.; a movable valve body inside this chamber, when in its normal posn., prevents any communication between these two passages and but, when moved to a second posn., provides communication between them. During inflation and adjustment of the tyre pressure, the valve can be moved to the second posn. so that excess pressure in any one chamber, discharging into the discharge duct can pass into the supply duct and thus enter some or all of the other chambers; in this way a balance of pressure throughout all the chambers is obtd.

Tire arrangement, for wheels of automobiles and other vehicles

Solid rubber tyres incorporating laterally adjacent hollow tubes - with an elastic foam bridge to enhance the lateral radial stiffness ratio

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.

The chambers 20 may each be inflated via a valve (not shown) in its wall 17 to a pressure higher than that of chamber 15. Alternatively, the chambers 20 may each contain a flexible cellular material. The carcass reinforcement may comprise a single ply of cord fabric 21 the edges of which may overlap or terminate as illustrated in Fig. 1, or may comprise two plies 21a, 21b (Fig. 3). The cords may be radial, or oblique with cords in adjacent plies crossing. The plies may be interrupted in the crown of the tyre. Further, reinforcing fabric strips 24, 25 may be provided. In the tyre of Fig. 3, the plies 21a, 21b may comprise metal and textile cords respectively in order that the inner walls 18 may be stiffer than walls 17. The differing stiffnesses may be achieved by a higher filament density or heavier filaments for the inner ply or a harder rubber for the inner ply. The walls 17, 18 may alternatively each be reinforced by one or more layers of a rubbery mixture containing, preferably orientated fibres. Support pads 31 (32) may be provided on the sidewalls and/or the tread and may comprise a self-lubricating rubber or may be covered with a layer of friction-less material. The apex strips 29 may extend into the inner walls 18 (Fig. 5, not shown) in which case chafer strips (26) are provided which extend from each bead seat into the outer walls 17.

PNEUMATIC ROLLER WITH CARRIER STRUCTURE

Motor vehicle wheel assembly which is unpuncturable, cannot slip off its rim and has a constant surface pressure

This assembly consists of a leaktight tyre 1 of volume V1, pressure P1 and of an inner tube 2 with volume V2, pressure P2. This tube is provided with a valve 3 for its own inflation and with a special valve 4 for inflating the tyre. The relations V1/V2 = P2/P1 or P1 x V1 = P2 x V2 estabish constant. The volume V1 with its pressure P1 which are defined by the manufacturer must be invariable in terms of respective values for a rational use of the wheel. When V1 decreases due to a puncture, V2, by compensation, tends to be substituted for V1. During this period, P2 decreases in terms of relative value in V2. This pressure changes on the basis of the variants V2. The volumes V1 and V2 are inversely proportional to the pressures P1-P2. The special inner tube materialises the desired objectives, due to autonomy.
