The present invention relates to a stabilizer manufacturing method including joining a stabilizer link for coupling a suspension device to a stabilizer, which are provided in a vehicle, to a stabilizer, thereby manufacturing the stabilizer to which the stabilizer link is joined, and a joint structure for a stabilizer link.
A vehicle is provided with a suspension device that absorbs and reduces impact and vibration transmitted from a road surface to a vehicle body via wheels, and a stabilizer for increasing a roll rigidity of the vehicle body. In order to couple the suspension device to the stabilizer, a rod-shaped member called a stabilizer link is used in the vehicle. For example, as shown in Patent Literature 1, a stabilizer link includes: a support bar; and ball joints that are provided at both ends of the support bar.
The stabilizer link according to Patent Literature 1 includes: a ball stud including a ball portion and a stud portion; and housings that are provided at both ends of the support bar, and each housing turnably houses the ball portion of the ball stud. A ball seat made of resin is provided inward of the housing so as to be interposed between an inner wall of the housing and the ball portion of the ball stud.
Patent Literature 1: JP 2016-84057 A
In order to join the stabilizer link according to Patent Literature 1 to the stabilizer, plate-shaped mounting portions that are formed by press working are respectively provided at both ends of the stabilizer. Through-holes are respectively opened in the mounting portions. The stud portion of the ball stud is caused to penetrate through the through-hole that is opened in the mounting portion of the stabilizer. A female screw of a nut is screwed onto a male screw provided on a penetration-side of the stud portion that protrudes from the through-hole. With such a screw joint, the stabilizer is joined to the stabilizer link.
However, the joining method that uses the screw of the stabilizer link according to Patent Literature 1 requires, as a measure against loosening of the female screw of the nut from the male screw of the stud portion, for example, precise management on the size of the mounting portion, the smoothness in the surrounding of the through-hole that is opened in the mounting portion, the film thickness of the coating material, and so on. As a result, the joining method for a stabilizer link according to Patent Literature 1 still has room for improvement in a cumbersome measure against the separation of the joint of the stabilizer link from the stabilizer.
The present invention is made in view of the abovementioned circumstances, and aims to provide a stabilizer manufacturing method capable of embodying a rigid joint of a stabilizer link with respect to a stabilizer that does not particularly require a measure against separation of the joint.
