Definitions

  • the invention relates to technycal and functional improvements related to a tyre , which is puncture proof and has a substantially softer ride in comparison with other non pneumatic tyres , being therefore specially suitable for use in many types of industrial and off-the-road vehicles like: forklift trucks , loaders ,backhoes , skid steer loaders and others.
  • Tube or tubeless tyres inflated with air or nitrogen which enable a soft ride , good traction , good load capacity , but are subjected to punctures , having as consequence vehicle downtimes.
  • Another disadvantage,due to the elastomer type utilized in their fabrication is that such tyres generally make black marks to floors .We may still point out as other disadvantages that such tyres are subjected to explosion due to carcass fatigue , with the possibility of hurting operators , and need frequent inflation pressure checkings.
  • Tube or tubeless tyres filled with an elastomer resin which still have the disadvantage of making black marks to the floors where they ride .Their tread thickness is generally smaller when compared with a solid tyre , having therefore a shorter useful life .
  • These tyres have the same advantages of air or nitrogen filled tyres , with the aditional benefits of being puncture proof and avoiding explosions and frequent inflation pressure checkings,as described in the US Patent # Re 29.980 from 01/1979 or in the Brazilian Patent # PI 8325/74.In general , such tyres are elastomer filled after being attached to a vehicle rim .
  • Solid rubber tyres- this type of tyre is generally bonded to the vehicle rim and is manufactured with an homogeneous hardness elastomer in the whole tyre structure,offering the advantage of being puncture proof , but suffering from the great disadvantage of supplying a very hard ride to the vehicle,with vibrations and impacts being transmitted more intensely to the vehicle and operator , causing damage for both of them.
  • its radial deflection as well as its footprint is smaller than that of a pneumatic tyre , what diminishes its power of traction.
  • These tyres may be manufactured using marking or nonmarking elastomers,but the majorative part of them make black marks to the floor where they ride.
  • tyres examples may be found in the brazilian patents # PI9.201.758 e MU7.402.449-3. Due to their very thick tread , the solid tyres may offer a longer useful life in comparison to pneumatic tyres . Generally the tread thickness of a solid tyre is 2 to 6 times thicker than that of a pneumatic tyre.
  • Superelastic solid rubber tyres- their construction is of the kind - 3 -
  • one inner radial layer comprising cord or wire reinforcements , made out of a very hard rubber , which will be in contact with the vehicle rim after attachment by pressing ; one intermediate radial layer bonded to the inner layer , made out of a softer rubber , whose function is to absorb impacts and give a softer ride ; and one outer layer bonded to the intermediate layer , made out of a rubber with high abrasion resistance , which comprises the tread .
  • uch tyres are attached through pressing to common rims , normally used with pneumatic tyres .These tyres remain attached to the rims , without slippage , due to the mechanical interference between the rim and the tyre , what generates a compression force that counteracts the momentum generated during the vehicle ride.
  • the superelastic solid rubber tyres offer a softer ride , when compared with regular solid rubber tyres .
  • the superelastic tyre ride is harder .They also offer the advantage of being puncture proof and may be manufactured using non marking elastomers. Examples of such tyres may be found in the patents PI 8402893 (brazilian) ,US 5.429.165 , JP A-61-44005 e JP A-64-83405.
