摘要:
Preparations for the sealing of tires with punctures are proposed, which contain the latex of synthetic isoprene rubbers or the latex of natural rubber together with latexes of synthetic isoprene rubbers, acrylate rubbers and/or methacrylate rubbers. The sealing preparations can contain an adhesive resin compatible with the latexes from the group comprising polyvinyl esters, polyvinyl alcohol and/or polyvinyl pyrrolidone, and also a pigment, with natural rubber latex, synthetic rubber latexes or their mixtures being used as rubber latex. Furthermore, an apparatus is described for the sealing and pumping up of the tire using an airbag inflation charge and also tires with an integrated sealing preparation.
摘要:
A tire sealant and inflator composition for the repair of puncture wounds in pneumatic tires and the like. The composition utilizes a sealing component consisting of an acrylic resin dissolved in a suitable solvent and a hydrochlorofluorocarbon and/or hydrofluorocarbon propellant component to deliver the sealing component from an aerosol container into the tire to a driveable state.
摘要:
Sealing and inflating system incorporated with a vehicular wheel including a tire rim and a tire mounted to the tire rim including a source of sealing and inflating compound arranged in connection with the tire or tire rim, a detecting mechanism for detecting a rupture in the tire, and a release mechanism coupled to the source and the detecting mechanism for releasing a quantity of the sealing and inflating compound from the source when the detecting mechanism detects a rupture in the tire. The source, detecting mechanism and release mechanism can all be arranged in the pressurized interior space defined by the tire and the tire rim. In this case, the source can be attached to the tire rim. One such construction of the source has two substantially semi-circular parts arranged around the tire rim and connected together, with a release mechanism being arranged in engagement with each part.
摘要:
An apparatus is provided for sealing of a damaged inflatable article, the apparatus including a container (1) for a sealant compound or composition, the container including at least one inlet means (4) which is releasably attachable to a source of pressurised air/gas, an extraction assembly (10 associated with the container (1), the extraction assembly (10 including an extraction unit having at least one outlet means (18) to be releasably coupled with or connected to the article and means (30) to be disposed within the container (1) and actuatable, upon supply of pressurised air/fluid/gas to the =container (1) to allow for controlled dispensing of the sealant compound or composition from the container (1) via the extraction unit (10) to the article to be sealed.
摘要:
The invention relates to an apparatus for the sealing of inflatable articles, in particular tyres, comprising a container containing a sealant and an extraction unit releasably connected and preferably screwed to the container, the extraction unit having at least one inlet line connectable to a source of gas pressure and at least one outlet line capable of being coupled to the article to be sealed, wherein ends of the lines which project into the container are sealed in a fluid tight manner relative to the inner space of the container by a closure arrangement which can be removed and in particular blown off by means of gas pressure.
摘要:
A method for correcting dynamic unbalance of a pneumatic tire which comprises adhering a counter weight to an inner surface of the tire to reduce dynamic unbalance of the tire, wherein the counter weight is made of a material having a specific gravity in a range of from 0.016 to 0.21 such as a strip of a spongy material.
摘要:
A pneumatic tire having a "run-flat" capability, is disclosed. The tire is in the form of a substantially toroidally shaped carcass having a pair of bead-reinforced sidewall regions and a crown region annularly bridging the sidewall regions. Internally of the carcass, there is provided an expandable nail-deflector for deflecting a nail that punctures, for example, the crown region. The nail deflector has a releasably constrained normal condition when the crown region is puncture-free that is annularly spaced from the interior of the crown region, and is circumferentially self-expandable into engagement with the interior of the crown region upon puncture of the latter by a nail to deflect such nail harmlessly away from its path of entry.
摘要:
A pneumatic tire and wheel assembly containing a lubricant composition for lubricating the internal surfaces of the assembly when in use in a deflated or substantially under-inflated condition. The composition includes a volatile component to at least partially reinflate the assembly and a puncture sealing material comprising a shredded and/or ground plastics material. A lubricant composition is also included.

摘要:
A method of allowing control of a vehicle with at least two-wheels in case of puncture of a tyre, each wheel including a rim and a tyre associated therewith, includes the steps of: inflating each tyre to an operating pressure; admitting a fluid compressed to a first pressure higher than the operating pressure of the tyre into at least one tank associated with at least one of the rims; bringing the tyre into communication with the tank when the inner pressure of the tyre is lower than a predetermined first threshold value; detecting a variation of an inner pressure of the tank; activating a pressure measuring device when the inner pressure variation corresponds to a reduction and is higher than a first predetermined value; measuring the inner pressure of the tank with a predetermined frequency by means of (through) the pressure measuring device; calculating a variation in the inner pressure in a time unit; generating an alarm signal when the calculated inner pressure variation corresponds to a reduction and is higher than a second predetermined value; and transmitting the alarm signal to the driver.
