Patent number: 9199512Abstract: A tire having a modified geodesic belt is described. The ideal geodesic belt path is modified to select the centerline belt angle and to avoid excessive build up of the belt at the belt edges. The method includes the step of calculating the minimum three dimensional distance from one belt edge to the other belt edge preferably using dynamic successive approximation.Type: GrantFiled: March 11, 2013Date of Patent: December 1, 2015Assignee: The Goodyear Tire & Rubber CompanyInventors: Kiyoshi Ueyoko, Luis Antonio Cabrera, Loyda Mercedes Yerashunas, John Joseph Slivka, James Michael Hart

Publication number: 20130056126Abstract: A pneumatic tire in accordance with the present invention includes two annular bead portions, a carcass, and a belt reinforcement layer. The carcass extends between the bead portions through sidewall portions and a tread portion. The carcass has at least one carcass ply of parallel cords turned up about the bead portions. The belt reinforcement layer is disposed radially outside the carcass and radially inside the tread portion. Each annular bead portion includes an annular bead core having the carcass ply turned up around the bead core, a first apex disposed adjacent and radially outward of the bead core, a second apex disposed axially outward of the bead core and the carcass ply, a first chafer disposed adjacent the carcass ply and axially outward of the bead core, and a second chafer disposed adjacent and axially outward the second apex and axially inward a sidewall portion. The first apex comprises a material with a 100 percent modulus between 1.0 MPa and 6.0 MPa.Type: ApplicationFiled: September 6, 2011Publication date: March 7, 2013Inventors: Kiyoshi Ueyoko, Leonard James Reiter, Maure Ellen Knavish, David Charles Wagner, David Paul George, Bret Herbert Marts, John Joseph Slivka

Patent number: 7950430Abstract: Pneumatic tires for aircraft service having a belt package with shoulder reinforcement. The tire includes a belt reinforcing structure or belt package having multiple cut belts, multiple spiral wound belt layers positioned radially between the cut belts and the tread, and multiple spiral wound shoulder layers proximate the shoulder. The spiral wound belt layers and the spiral wound shoulder layers are formed by a continuous cord-reinforced strip having a strip width. The spiral wound belt layers are characterized by a first winding pitch of approximately one strip width per revolution and the spiral wound shoulder layers are characterized by a second winding pitch of less than one strip width per revolution. Alternatively, the spiral wound shoulder layers may be formed with a tiered arrangement by shifting the starting location for successive spiral wound belt layers laterally so that the side edges are not coincident.Type: GrantFiled: April 6, 2007Date of Patent: May 31, 2011Assignee: The Goodyear Tire & Rubber CompanyInventors: Roel Domingo Villanueva, John Joseph Slivka

Patent number: 7789120Abstract: A pneumatic tire having a carcass and a belt reinforcing structure wherein the belt reinforcing structure is a composite belt structure having at least one pair of radially outer zigzag layers and at least one spirally wound belt layer with cords inclined at an inclination of 5 degrees or less relative to the tire's centerplane and located radially inward of and adjacent to the at least two radially outer belt layers. The at least two radially outer zigzag belt layers have cords inclined at 5 degrees to 30 degrees relative to the tire's centerplane and extending in alternation to turnaround points at each lateral edge of the belt layer. At each turnaround point the cords are folded or preferably bent to change direction across the crown of the carcass thus forming a zigzag cord path.Type: GrantFiled: April 11, 2005Date of Patent: September 7, 2010Assignee: The Goodyear Tire & Rubber CompanyInventors: Kiyoshi Ueyoko, John Joseph Slivka, Roel Domingo Villaneuva, Robert John Boehlefeld

Patent number: 7467653Abstract: An aircraft tire having a folded belt construction and a belt edge strip over the folded belt construction has improved high speed properties. The belt edge strip substantially covers the top surface and/or the bottom surface of the folded belt in addition to the folded belt edges. The folded belt construction is reinforced with high modulus materials, and the belt edge strip is reinforced with low modulus materials. In a method of the invention, plies which make up the belt reinforcement package are applied to a belt building drum while the building drum is at different diameters to minimize stresses on the belt package. In a method of building a tire of the invention, a tire carcass on a tire building drum is expanded to the belt package.Type: GrantFiled: November 27, 1996Date of Patent: December 23, 2008Assignee: The Goodyear Tire & Rubber CompanyInventors: John Joseph Slivka, Thomas William Cooper, Hal Warren Stilley, Jr., Oscar Allen Hash, Jerome Wesley Ward

Patent number: 7360571Abstract: A method of forming a composite belt structure for a tire is disclosed. The composite belt structure has cord reinforced layers including at least two radially outer zigzag belt layers. The cords per inch in the shoulder portion are greater than the cords per inch in the central portion as measured centered on the centerplane of the belt structure. The method discloses the steps of applying a multicord reinforced strip having a strip width SW onto a rotating crowned building drum, the strip being wound in a zigzag configuration to form at least two zigzag layers, wherein the crowned drum has non-overlapping portions of the strip placed in a central portion and extending in alternation to a pair of shoulder portions having portions of the strips overlapping to form belt layers.Type: GrantFiled: September 16, 2003Date of Patent: April 22, 2008Assignee: The Goodyear Tire & Rubber CompanyInventors: Kiyoshi Ueyoko, John Joseph Slivka, Roel Domingo Villanueva, Robert John Boehlefeld
