Title:
DUST COVER FOR BALL JOINT
Document Type and Number:
WIPO Patent Application WO/2013/038886
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a dust cover for a ball joint whereby even in low-temperature conditions in which physical properties of elastic materials degrade, the problem of cracks forming in a large-diameter opening in the dust cover is resolved effectively. A ball-head part formed at one end of a ball stud is held inside a socket, and a shaft at the other end of the ball stud is clamped to a knuckle. This dust cover is made from an elastic material. An annular retaining ring is used to fixedly hold a large-diameter opening at one end of the dust cover, the cross-section of said opening being roughly U-shaped, in a ring-shaped groove section formed in the outer surface of the socket. A small-diameter opening at the other end of the dust cover is held by the abovementioned shaft. The small-diameter-opening-side corner of the inner surface of the large-diameter opening is made into a ring-shaped angled surface, and the part of the aforementioned groove section that contacts said angled surface is made into a ring-shaped angled section having roughly the same shape as said angled surface.
