  • Method of forming an airspring with pneumatic fitting
    Patent number: 4715107
    Abstract: An airspring with plastic rigid components having a specialized coupling adapted for push-in engagement of the pneumatic tubing into the airspring is disclosed. The coupling requires no threading in the plastic structural component of the airspring and is composed of an outer ring through which a coaxial annular sleeve with jaws for tubing engagement slides axially. An O-ring seals the tubing against air leaks. The airspring may be used for vibration isolation or load suspension.
    Type: Grant
    Filed: June 12, 1986
    Date of Patent: December 29, 1987
    Assignee: The Goodyear Tire & Rubber Company
