Patent number: 11285757Abstract: The present invention relates to a novel design for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The invention provides a safe design that comprises a two-piece segmented saddle lock ring retained in position by an endless ring. A self-locking taper provided on the inside of endless ring can be pressed against the taper provided on the two-piece segmented saddle lock ring. The endless ring retaining the two-piece segmented saddle lock rings due to wedge action of self-locking taper cannot move from its position until an external force is applied on the endless ring towards the direction of the tyre position. The endless ring acts as a hood over the two-piece segmented saddle lock rings and prevents any loose parts flying off the rim during the tyre burst. Further in this safe design both inboard and outboard rim tyre support components are identical as both rims are of same diameter.Type: GrantFiled: September 29, 2016Date of Patent: March 29, 2022Inventor: Balaji Avalur Nagarajan

Patent number: 4706723Abstract: An improved rim for use on a heavy, off-road vehicle formed of a tubular rim base member having a circumferential groove in the outer cylindrical surface adjacent one end thereof, the groove being of semi-circular cross-sectional configuration, a first bead flange secured at one end of the rim base member, a second bead flange slidably mounted on the other end of the rim base providing a contour substantially the same as the inner contour of the first bead flange, the second bead flange having a circumferential recess in the inside surface at the outer end thereof, and a split circular cross-sectioned locking ring removably received within the base member circumferential groove so that when the second bead flange is slidably positioned on the rim base, the locking ring can be placed in the groove and when the second flange slides outwardly the recess therein retains the locking ring within the groove and the locking ring serves to retain the second bead flange on the rim.Type: GrantFiled: April 14, 1986Date of Patent: November 17, 1987Assignee: Unit Rig & Equipment CompanyInventors: Frederick W. Loeber, Nolan W. Cummins, Rodger L. Modglin, George O. Greene

Patent number: 4683930Abstract: A split retaining ring for locking a separable tire bead flange on a wheel rim has inboard and outboard facing portions and two circumferentially aligned terminal ends, each terminal end characterized by an outboard facing tab having a drilled-through bore. A buckle member having a pair of apertures is mounted on the retaining ring such that each tab passes through a respective aperture and the buckle functions to maintain the terminal ends of the retaining ring in a specific orientation when it is mounted on a wheel rim. A wire fastener is positioned through each drilled bore in a tab to retain the buckle member on the split retaining ring.Type: GrantFiled: October 31, 1985Date of Patent: August 4, 1987Assignee: Goodyear Aerospace CorporationInventors: Paul A. Elam, Jack W. Keller

Patent number: 4649978Abstract: A vehicle is supported by wheel and tire assemblies. The assemblies each have a tire mounted around a cylindrical wheel rim and retained in place by an annular retaining ring that abuts the wheel rim and the tire. A lock ring is located in an annular groove in the wheel rim and abuts the retaining ring to hold the retaining ring in place against the tire. A tension plate is connected to the retaining ring through a set of tap screws to hold the tension plate against the end of the wheel rim and thereby retain the annular ring and the tire against rotation around the rim.Type: GrantFiled: January 7, 1985Date of Patent: March 17, 1987Assignee: Ingersoll-Rand CompanyInventor: Gregory A. McCoy

Patent number: 4635695Abstract: A split retaining ring 60 locking a separable tire bead flange 14 on a wheel rim 10 has inboard 60a and outboard 60b facing portions and circumferentially aligned terminal ends 40, 50, each terminal end characterized by a drilled-through bore 46, 56 extending in the axial direction of the ring from the inboard facing portion to the outboard facing portion. A lockwire 70 is positioned through each drilled bore 46, 56 to retain the terminal ends 40, 50 of the split ring in a predetermined circumferential spaced-apart relationship.Type: GrantFiled: October 31, 1985Date of Patent: January 13, 1987Assignee: Goodyear Aerospace CorporationInventors: Richard J. Frank, Donald H. Smith

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. Smith

Patent number: 4566515Abstract: A wheel and tire assembly for a vehicle, including a solid rubber tire, and a wheel body, one or both edges of which are provided with a circumferential groove for receiving a retaining ring for the solid tire. In order to be able to repeatedly mount the solid tire with a sufficiently reliable seating, there is inventively proposed to provided the solid tire with a base having a width such that when the retaining ring is omitted, the tire extends slightly into the region which would otherwise be occupied by the retaining ring. Accordingly, when the retaining ring is inserted, the base of the tire must be slightly elastically deformed, thus assuring a secure seating of the tire on a wheel rim therewith.Type: GrantFiled: January 18, 1985Date of Patent: January 28, 1986Assignee: Continental Gummi-Werke AktiengesellschaftInventor: Heinz Kuhn

Patent number: 4554961Abstract: A bottom surface portion of a lockring groove defined by a rim base is formed to be an inclined surface on which a load in a radial direction acts through a lockring. A leg portion of the lockring having an annular body engaged thereto is formed to be an inclined surface so as to abut the inclined surface of the lockring groove defined by the rim base.Type: GrantFiled: November 30, 1982Date of Patent: November 26, 1985Assignee: Topy Industries LimitedInventors: Shigeru Osawa, Hisayoshi Yamoto

Patent number: 4530387Abstract: In a cylindrical surface of a gutter band of a wheel rim and a cylindrical surface of a spider hub opposed to one another, a conical surface is formed on one side of the cylindrical surface of the gutter band or that of the spider hub, or on both respectively. A wedge member is inserted between the formed conical surface and the cylindrical surface, or the formed conical surfaces, thereby forming a spider hub and wheel rim assembly.Type: GrantFiled: September 14, 1982Date of Patent: July 23, 1985Assignee: Topy Industries, LimitedInventor: Shigeru Osawa
