Abstract:
A ball stud, a dust cover, and a stabilizer link with them, in which the sealing characteristics are improved and the weights thereof are reduced, while assembling productivity in a mass production line is improved, are provided. A ball stud 110 has a flange 111 that outwardly projects in a radial direction of a stud portion 210. The flange 111 has a concave portion 112 that has a curved shape from a root to an outer circumferential portion in cross section. The concave portion 112 is concave with respect to a straight line connecting an end 112A on the root side and an end 112B on the outer circumferential portion side of the curved shape. A dust cover 121 has a lip 122 to be abutted on a sealing portion 212 and the flange 111 of the ball stud 110. The lip 122 has a circumferential end that is formed with a side lip portion 123. The side lip portion 123 has a shape corresponding to the curved shape of the concave portion 112 of the flange 111 so as to be abutted on the concave portion 112.

A ball joint 10 includes: a ball stud 100 having a columnar stud portion 110 and a ball portion 120 which has a spherical side surface and a center positioned on an axis of the stud portion; a ball seat 210 which is made of a resin and has a spherical recess portion 212 into which the ball portion 120 is relatively rotatably and slidably fitted; a housing 220 which is made of a resin and holds the ball seat 210 therein; and a support bar 230 which is integrally formed with the housing 220, wherein the support bar 230 has a bar portion 231 which is a center portion extending along an axis of the support bar.
Abstract:
An axial ball joint is provided with: a ball stud including a stud section and a ball section; a metallic housing which rotatably supports the ball section of the ball stud; and a resin-made ball seat which is provided to be interposed between the ball section and the housing. The housing is formed into a bottomed cylinder shape by pressing. The thickness of a bottom wall and the thickness of a circumferential side wall of the housing are set to be equal to each other. A plurality of bead sections are formed on the inner bottom of the housing by press-molding or forging.
Abstract:
The ball joint manufacturing method for manufacturing a ball joint including a ball stud which includes a substantially spherical metal ball section, and a resin housing rotatably accommodating the ball section of the ball stud, includes: a step of forming the housing to cover an outer periphery of the ball section; an induction heating step of subjecting the ball section to induction heating in a state in which the ball section is accommodated in an accommodation section of the housing until the temperature of the ball section reaches a predetermined target temperature; and a cooling step of cooling the ball section which has been subjected to the induction heating, wherein a torque adjustment step including the induction heating step and the cooling step is repeatedly performed.
Abstract:
This stabilizer link (11) includes a metal support bar (12), and ball joints (13) that are provided at both ends of the support bar (12). Each ball joint (13) includes a ball stud (21) one end of which is fastened to a suspension device (15) or a stabilizer (17), and which has a ball part (21b) at the other end thereof, and a housing (23) that rotatably supports the ball part (21b) of the ball stud (21). The support bar (12) includes: a body part (12a) extending in a nearly linear shape, and reinforcement parts (12b) each having a nearly annular shape and each provided at both ends of the body part (12a). The reinforcement parts (12b) of the support bar (12) are each embedded in the housing (23) so as to surround the ball part (21b).
Abstract:
A ball joint (1b) according to the present invention is provided with: a ball stud (10); a housing (11); and a ball sheet (sheet (12)). The sheet (12) is formed into a vertically-open cylindrical shape by an elastic body, and has a spherical space that houses a ball part (10b) in a cylindrical manner. The housing (11) has a spherical inner surface (11a) near the outer circumferential surface of the ball part (10b), and supports the ball stud (10) by housing the ball part (10b) in the inner surface (11a) with the sheet (12) therebetween. Caulking parts (11k) that are the circumferential end parts of the housing (11) perform caulking such that the ball stud (10) pushes the sheet (12) in a swingable and rotatable manner.
Abstract:
The present invention provides a stabilizer manufacturing apparatus (S) that is adapted to bond a rubber bush (3), which is a bush made of rubber disposed between a stabilizer (1) and a vehicle body, to a rubber bush bonding location (1s) where an adhesive layer of the stabilizer (1) is formed. The stabilizer manufacturing apparatus is provided with: a curing furnace (R) for heating the stabilizer (1), which is conveyed by a manufacturing line conveying unit (4) and has the rubber bush bonding location (1s) with which the rubber bush (3) is press-contacted, and performing the bonding; a heat source device (5) that heats air; a blower device (f1, f2, f3) that sends the air heated by the heat source device (5) as hot air; and a plurality of nozzles (7) that are disposed along the manufacturing line conveying unit (4) in the curing furnace (R) and blow the hot air against, at a near position from, a location (1a1) in the vicinity of the rubber bush bonding location (1s) of the stabilizer (1).
Abstract:
In the bonding of the bush to the bar of the stabilizer, by surface pressure in the bonding surface (inner circumferential surface) of the hole part of the bush being made uniform, a necessary bonding strength can be obtained. The first arc part 101 is formed at the opposite side of the opening part of the U-shaped part 41 of the bracket 40 used in the bonding ( Fig. 3B ) and the second arc part 102 is formed in the opening part side, in the hole part 100A of the bush 100. The first arc part 101 and the second arc part 102 are the circular arc part being formed in the circular arc shape or approximately circular arc shape, for example, or are the ellipse arc part being formed in the ellipse arc shape or approximately ellipse arc shape, for example. In the hole part 100A, the center O1 of the first arc part 101 and the center 02 of the second arc part 102 are separated. The curvature radius r2 of the second arc part 102 is formed smaller than the curvature radius r1 of the first arc part 101. The hole part 100A is desirably formed in an oval shape as shown in Fig. 6 , for example.
