摘要:
A tire (12) having a tire cavity, first and second sidewalls (16, 22) extending respectively from first and second tire bead regions (18, 24) to a tire tread region (20), an annular air passageway (26) integrally formed and enclosed within a tire sidewall (16, 22) and forming at least one loop (46, 48, 50, 52, 54) at least substantially circumscribing the tire sidewall (16, 22) is disclosed. The air passageway (26) is operative to progressively flatten segment by segment by a rolling tire closing patch whereby progressively pumping air along the air passageway (26). The tire (12) comprises an inlet air passageway portal (32) operative to pass air into the annular passageway (26) and an outlet air passageway portal (34), wherein the outlet air passageway portal (34) is operative in an open position to pass air from the annular air passageway (26). The inlet air passageway portal (32) and the outlet air passageway portal (34) are located in a proximal relationship operative to place the inlet air passageway portal (32) and the outlet air passageway portal (34) within a common passageway segment closing patch (38) as the tire rotates (12).
摘要:
A tire having a tire cavity (30) between first and second sidewalls that extend respectively from a pair of beads (22) to a tire tread region and an air passageway body (46) extending between an outward facing tire surface and the tire cavity (30) is disclosed. The air passageway body (46) has an enclosed air passageway extending between a hollow body outlet end (54) facing the tire cavity (30) and a hollow body inlet end (52) facing outward from the outward facing tire surface. At least one tapping device (74,92) is affixed over at least one of the ends (52, 54) of the air passageway body (46), the at least one tapping device (74,92) having a vent opening and a protrusion member (88,100) penetrating through a wall of the air passageway body (46). Also, a method of manufacturing such a tire is disclosed.

A tire tread comprising a structure (100, 200, 300), the structure comprising a radially extending pedestal (110, 210, 310), a first set of voids (111, 211, 311) extending radially through the pedestal (110, 210, 310), a second set of voids (122, 222, 322) extending radially through the pedestal (110, 210, 310); and a radially extending void ring (133, 233, 333) circumscribing the pedestal (110, 210, 310) is disclosed.
摘要:
An anti-slip structure for disposal in a recesses or a tire tread band (34) is described. The structure (100, 200) comprises a first, radially inner portion (110, 210), a second, radially outer portion (120, 220) and a third, core portion (130, 230). The core portion comprises an assembly of a plurality of pin structures (132, 232) for providing traction over ice, each pin structure having a base portion (134, 234) secured within the first portion (110, 210) and a pin (136, 236) extending through the second portion (120, 220). The base portions (134, 234) form or combine to a common base portion of the assembly.
摘要:
A pneumatic tire tread has tread elements (10) formed by circumferential and/or lateral grooves. At least one tread element (10) has a sipe that devolves from a constant width sipe having a three dimensional aspect in at least a portion of the radially outer portion of the sipe to a wider width groove at the base of the tread feature. Also a blade (26, 44) to create such a sipe is disclosed.
摘要:
A tire comprises a tread (34) having a radially outer tread surface (35) and a plurality of radially extending recesses, and an anti-slip structure (100) disposed in at least one of the radially extending recesses. The anti-slip structure (100) comprises a housing (110) with a displacement restricting element and a channel and a stud portion (130) comprising a shaft (132) and a displacement restricting element (134). The shaft (132) is slidingly disposed within the channel such that a radially outer tip (136) or end of the shaft (132) may selectably extend radially outward from the housing (110) and from the radially outer tread surface (35). The radially outer tip (136) or end extends from the housing (110) and from the radially outer tread surface (35) when a predetermined air pressure is introduced into the radially extending recess thereby forcing the displacement restricting element (114) of the stud portion (130) radially outward.
