Patent number: 4574859Abstract: A multi-piece rim assembly comprises a rim base, sealing member, lock ring and bead seat band. The sealing member and lock ring have specified positions such that each is at least partially disposed in an annular groove in the radially outer surface of the rim base, with the lock ring being nearer to an axial end of the rim base than the sealing member. The bead seat band is coaxial with and slidably mounted around the rim base. When all of the components of the rim assembly are in their specified positions, the bead seat band engages the sealing member to form an airtight seal. If the entire lock ring is not in its specified position, an axial end of the bead seat band contacts the lock ring and prevents the airtight seal from being formed.Type: GrantFiled: May 14, 1985Date of Patent: March 11, 1986Assignee: The Goodyear Tire & Rubber CompanyInventor: William T.

Patent number: 4481997Abstract: A safety tire and wheel assembly which includes an improved multiple-piece wheel rim assembly for preventing inflation and/or venting to atmosphere when the rim assembly components are improperly assembled, and an improved safety insert mounted on the wheel rim base for supporting the tire tread during operation following loss of inflation pressure. The wheel rim assembly includes telescoping rim segments and an O-ring normally captured in compression between opposing portions of the rim segments for sealing the tire cavity. Air bleed passages are formed in one rim segment adjacent the sealing ring externally of the cavity to vent the tire cavity to atmosphere when sealing compressive stresses are absent from the O-ring as in the event of improper assembly or disassembly. The safety insert includes a ledge normally disposed within the tire cavity and having a radially facing surface roughened by a circumferential series of axially extending splines.Type: GrantFiled: November 5, 1982Date of Patent: November 13, 1984Assignee: Motor Wheel CorporationInventor: Don S.
