Patent number: 5129634Abstract: A vehicle suspension strut incorporating an airspring around a hydraulic shock absorber is disclosed. The unique airspring design and orientation relative to the shock absorber axis creates a side acting force which counteracts the bending torque acting on the strut during operation in a vehicle and prevents binding of the shock absorber piston. The horizontal side load is achieved using a partial restraining sleeve which circumferentially shrouds the flexible member of the airspring. The partial restraining sleeve extends less than half way around the circumference of the airspring flexible member and has a radius less than the fully inflated radius of the flexible member therby creating a restraining force on only one side of the flexible member of the airspring.Type: GrantFiled: September 2, 1986Date of Patent: July 14, 1992Assignee: The Goodyear Tire & Rubber CompanyInventor: John R. Harris

Patent number: 4955411Abstract: Mandrel-cured, curved elastomeric hose is provided with an indexing mark that is formed prior to or during curing of the hose on the mandrel. The rigid curved mandrel has an exterior hose-bearing surface and an interior cavity. The cavity and exterior surface are connected by a small passageway or hole which is located where the index mark is to be made on the hose. A sleeve having a wall of uncured elastomeric material is mounted on the mandrel such that a portion of the sleeve covers the passageway. The mandrel having the sleeve mounted thereon is placed in an autoclave and subjected to steam pressure. The steam pressure forces elastomer material into the passageway and thereafter cures the elastomer sleeve into a hose. The pressure inside the cavity is approximately atmospheric at the introduction of the steam pressure. The cavity within the mandrel may be sealed except for the passageway or the cavity and the passageway may be vented to atmospheric pressure.Type: GrantFiled: September 9, 1985Date of Patent: September 11, 1990Assignee: The Goodyear Tire & Rubber CompanyInventors: Roy W. Olsen, Curtis H. Bell

Patent number: 4911416Abstract: A vehicle suspension strut incorporating an airspring around a hydraulic shock absorber is disclosed. The airspring design and orientation relative to the shock absorber axis creates a side acting force which counteracts the bending torque acting on the strut during operation in a vehicle and prevents binding of the shock absorber piston. The horizontal acting side load can be achieved by using an airspring piston eccentrically mounted on the shock absorber. Alternatively the airspring may be mounted offset and/or at an angle to the shock absorber axis. The flexible membrane of the airspring may also be cut in a plane oblique to the shock axis and mounted on the airspring piston to form asymmetric rolling lobes about the circumference of the piston.Type: GrantFiled: March 2, 1989Date of Patent: March 27, 1990Assignee: The Goodyear Tire & Rubber CompanyInventor: Ivan J. Warmuth, II

Patent number: 4856720Abstract: In a method of fabricating hose, especially in very long unbroken lengths, an elongated core is mounted for rotation without longitudinal displacement and is driven simultaneously at both of its ends at a selected fixed speed. A bobbin having a length of tape wound on it is moved on a carrier along a path parallel to the length of the core, and the tape of the bobbin is wound helically onto the core while the core is rotating and the carrier is moving along the path. There may be plural bobbins, and the carrier may have a platform for a human operator who manipulates the bobbin from which tape is being wound. Tape from selected successive bobbins may be so wound in helical manner.Type: GrantFiled: March 27, 1984Date of Patent: August 15, 1989Assignee: The Goodyear Tire & Rubber CompanyInventor: Alfio Deregibus
