Embodiment Construction

[0031] Hereinafter, the ball joint and its manufacturing method of the present invention will be described in detail using the drawings.

[0032] figure 1 It is a figure which shows the 1st embodiment of the ball joint manufactured by this invention. This ball joint is formed by a ball stud 1 having a ball portion 10 at the tip of a shaft member 11, a resin sliding contact member 3 that covers the ball portion 10 and is in sliding contact with the ball portion 10, and a resin sliding contact member 3 formed on the resin sliding contact member 3. The member 3 is surrounded by a retainer 2 that fixes the resin sliding contact member 3, and the ball stud 1 is connected so as to be swingable relative to the retainer 2 centering on the ball portion.

[0033]The ball stud 1 is formed by resistance welding a rod-shaped shaft member 11 to a high-sphericity bearing steel ball serving as the ball portion 10 . The shaft member 11 is formed with a flange portion 12 provided with a suppo...

Abstract

The present invention relates to a ball joint in which a holder (2) is cast with a ball (10) as a core and a shaft member (11) is electric resistance welded to the cast ball (10), and a manufacturing method therefor. A ball joint is provided with: a ball (10); a resin sliding contact member (3) which has a first opening (31) and a second opening (32) from which the spherical surface of the ball (10) is exposed in opposite directions; a holder (2) which is cast with the ball (10) and the resin sliding contact member (3) as a core and with which a blocking part (23) that is being in contact with the ball (10) protruding from the second opening (32) of the resin sliding contact member (3) is integrally molded; and a shaft member (11) which constitutes a ball stud (1) by being joined to the ball (10) exposed from the first opening (31) of the resin sliding contact member (3) by electric resistance welding after the holder (2) is cast.

Description

technical field [0001] The present invention relates to a ball joint used in a link mechanism such as a stabilizer link of an automobile, a transmission control unit, and a method for manufacturing the same. Background technique [0002] As such a ball joint, what is disclosed in Japanese Unexamined Patent Publication No. 9-189322 (Patent Document 1) is known. The ball joint disclosed in this document is composed of a ball stud having a ball at the tip of the shaft member, which is the center of swing of the link mechanism, and the largest diameter portion of the ball portion of the ball stud that covers and slides on the spherical surface of the ball portion. The contact cage constitutes. [0003] The cage is formed by casting using the spherical portion as a core, and the spherical rotation of the spherical portion is formed at the cage by using steel balls for bearings with a high sphericity as the spherical portion. Printed metal sliding contact surfaces with high sphe...
