TH37643B - A locked air-tight tire With a wrap around the inner tube - Google Patents

Abstract

DC60 (05/03/56) An air compressor tire 10 consisting of a ribbed layer 12 or a tire layer 12, 14 with a locked structure. and wrap-around inner tube 18. Each wrap-around inner tube 18 is a single strip of unreinforced elastomer material. With a string that is wrapped around 360 degrees in a single ring-shaped inner tube A single band reinforced by the sheath's ligature. 18 laps around the inner tube rim can be made from a single elastomer mixture with a hardness D, measured in shoals greater than 40. Alternatively, The wrapped around the inner tube rim that is wrapped around. The tip 29 and the anti-friction part and the hub 27 may be used in addition to the cladding section of the inner tube 28, whereby each section 27, 29 shall be extruded together, or may was molded while hot and is heat-formed with the cladding section around the inner tube 28 to form a single strip 18, and it uses a different elastomer mixture than the cladding around the rim core. Inner tube 28 Pneumatic tires 10 consisting of ribbed layers 12 or tire layers 12, 14 with a locked structure. and wrap-around inner tube 18. Each wrap-around inner tube 18 is a single strip of unreinforced elastomer material. With a string that is wrapped around 360° in a single ring-shaped inner tube A single band reinforced by the sheath's ligature. 18 laps around the inner tube rim can be made from a single elastomer mixture with a hardness D, measured in shoals greater than 40. Alternatively, The wrapped around the inner tube rim that is wrapped around. The tip 29 and the anti-friction part and the hub 27 may be used in addition to the cladding section of the inner tube 28, whereby each section 27, 29 shall be extruded together, or may was molded while hot and is heat-formed with the cladding section around the inner tube 28 to form a single strip 18, and it uses a different elastomer mixture than the cladding around the rim core.

Claims (8)

1. A pneumatic tire consisting of a pair of locked bead strands, with the tire comprising a pair of axially spaced ring-shaped bead cores; at least one carcass layer reinforced with ligaments wrapped around each bead core, and at least one pair of carcass folds flanking the carcass layer from the outermost radial extension of the bead core axis to one or more ends radially outside the folds of the carcass folds; the bead strand wrapping, which is attached to each bead core, is a single unreinforced elastomer strip wrapped around at a 360° angle in the form of a single ring loop, with one and two ends directly against the carcass layer, the first end positioned on the inner axial side of the carcass layer. The point which protrudes radially from the inner tube core by approximately 0.4 inches (10 mm) to 3.5 inches (89 mm) when measured along the carcass ply, and the second such end comes into contact with the carcass ply fold, which is located between the outermost axial point of the inner tube core and the point which protrudes radially from the inner tube core by approximately 3.5 inches (89 mm) when measured along the carcass ply fold, and where the first and second ends of the inner tube core wrap are radially shorter from the inner tube core than the outermost radial point of the carcass ply by at least a fraction, and where the inner tube core wrap is an extruded strip without reinforcement made of a single elastomer composition with a Shore D stiffness greater than 40. 2. Pneumatic tire as defined in Reputation 1, in which the inner radial portion of the second end of the rim-wrapped section extends from the rim axis and the outer folded portion extends axially from the outer surface of the tire. 3. Pneumatic tire as defined in Reputation 1, where the outer radial portion of the second end of the rim wrap is superimposed by the sidewall portion of the tire. 4. Pneumatic tires as defined in Requisition 1, where the rim of such tire has a radial cross-sectional shape of a distinct group of polygons, hexagons, squares and circles. 5. Pneumatic tire as defined in Reputation 1, where the axis of such rim is distinctly a pentagon, with the greatest axial width of the rim radially outward from the innermost radial edge of the rim axis, and the outermost radial edge of the rim axis being the vertices of the two sides of that pentagon. 6. A pneumatic tire, as defined in Reputation 1, where at least one of the outermost radial ends of such end fold is attached to the carcass plies and extends radially outward from the axis of the tire bead to a point at a distance of 0.5 in (12.7 mm) to 3.5 in (88.9 mm) when measured along the carcass plies of the tire. 7. Pneumatic tires as defined in Requisition 1, where one end of the aforementioned bead-wrapped section rests on the inner axial point of the tire carcass layer at a point exiting radially from the bead core by 0.4 in (10.16 mm) to 2.0 in (50.8 mm). 8. Pneumatic tires as defined in Reputation 1, whereby the second end of the axle wrap is located at least 2.0 inches (50.8 mm) radially from the outermost axial point of the axle of the tire, measured along the fold end of one of the tire carcass layers.
