Definitions
- the present invention relates to a ball joint provided in a stabilizer mounted on a vehicle such as a car and a method of manufacturing the same.
- a ball joint is used.
- the ball joint comprises a ball stud having a stud portion and a ball portion, a ball seat having a bearing function by pressing the ball portion of the ball stud, a housing for accommodating the ball seat, a support bar for supporting the housing, and a ball seat And a dust cover that prevents foreign matter from impeding the sliding and rocking motions performed between the ball and the ball portion of the ball stud.
- the housing and the support bar are separately formed, and the support bar of the steel rod (for example, S20C) is joined to the housing manufactured by press forming or the like by resistance welding or CO 2 welding. .
- the support bar When the support bar or the like is formed of steel, the support bar is the heaviest of the weight of one ball joint among the ball stud, the dust cover, the support bar, and the ball seat which are components of the ball joint.
- the weight of a support bar having an axial length of 325 mm is 260 g
- the total weight of parts other than the support bar is about 130 g, which is twice the total weight of other parts. That is, 2/3 of the weight 390 g of one ball joint was the weight of the support bar. Therefore, the weight of the ball joint is heavy, and the contribution of the ball joint in reducing the weight of the vehicle is difficult.
- the support bar is joined to the housing by resistance welding or the like. Therefore, if an endurance test is performed by applying a tensile load or a compressive load in the axial direction of the support bar, It has been found that the welds fail a predetermined number of times ago. Therefore, with respect to the integrally molded housing and the support bar, there is a fear of strength at the joint portion, and there is a fear of securing the reliability of the ball joint.
- a method of manufacturing a ball joint in which a housing and a support bar are integrally formed of aluminum or the like for example, JP-A-2004-316771.
- a resin liner (ball sheet) is formed on a ball portion of a ball stud by injection molding. Then, the ball portion and the resin liner are inserted as a core into a mold for molding the housing and the support bar.
- the housing covering the resin liner and the support bar supporting the housing are integrally formed of zinc alloy or aluminum alloy by die casting. Then, the stud portion was connected to the ball portion.
- the outer surface of the resin-made ball sheet is deteriorated because the core of the ball portion of the ball stud and the ball sheet are injected and the melted aluminum alloy is injected during die casting. Therefore, although the ball sheet in the contact portion with the ball portion is well maintained, the slight nonuniformity of the resin thickness is inevitable, so the operation of the sliding and rocking motion of the ball stud becomes unstable. That is, when a tensile load or a compressive load is applied in the axial direction of the ball stud or in the radial direction of the ball portion, the amount of bending of the ball sheet varies, and the operation during sliding and rocking motion of the ball stud becomes irregular. . As a result, the performance of the ball joint could not be sufficiently exhibited, and the ball joint could not be said to be sufficiently reliable.
- the ball portion and the ball sheet of the ball stud are used as a core during die cast molding, if the stud portion is connected to the ball portion, the housing and the support bar can not be die cast molded. Therefore, after die-casting the housing and the support bar, the stud portion is joined to the ball portion by resistance welding or the like to form a ball stud. Therefore, there is concern about the strength at the joint between the stud portion and the ball portion, and there is concern in securing the reliability of the ball joint.
