Title:
BALL JOINT DUST COVER
Document Type and Number:
WIPO Patent Application WO/2014/208286
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a ball joint dust cover with which the so-called opening phenomenon at a small-diameter opening (wherein contact between the small-diameter opening and the shaft is lost) is prevented, and the small-diameter opening has good sealing performance, even in a low-temperature environment. A large-diameter opening at one end of this ball joint dust cover is affixed to and retained by the outer peripheral surface of a socket, and a small-diameter opening at the other end, in which a reinforcing ring formed of a hard material is integrally formed, is retained on a retainer having an L-shaped cross section and formed of a hard material, said retainer comprising a tubular part which is fitted onto and affixed to the outer peripheral surface of the shaft, and an outward flange part which extends radially outward from the socket-side end of the tubular part. This ball joint dust cover is configured such that the reinforcing ring comprises a cylindrical part, and an inward flange part which extends from the knuckle-side end of the cylindrical part toward the outer peripheral surface of the retainer, and the socket-side end of the cylindrical part of the reinforcing ring makes contact with the outward flange of the retainer.
