PNEUMATIC TYRE AND WHEEL OF PROPELLING DEVICE WITH SUCH TYRE Russian patent published in 1997 - IPC

FIELD: mechanical engineering and tyre industry. SUBSTANCE: position of rim point located on pneumatic tyre is defined by following dependences Carcass cord layers from rim point to bead rings in section are made straight-line, and straight neutral line of corresponding beads and reinforcement zones is inclined to equatorial plane at angle of . Generating surfaces of outer sides of beads over their length are equidistant to strength section of neutral line of corresponding reinforcement zones of tyre. Inclined portion of bead edges on wheel is arranged from bead foot to tyre sides, is straight and parallel with neutral line of corresponding beads and tyre reinforcement zones and length of inclined portion of edges is 0.3-0.8 of length of neutral line from base of bead to point of tyre rim. EFFECT: improved quality of tyre. 2 cl, 3 dwg
