Below, the manufacture method of the ball-joint 11 of an above-mentioned mode of execution is described.
At first, shown in (a) figure of Fig. 1, the inside (inner room 24) (insertion operation) of spherical bulb 41 from the second ball bowl opening portion, the 26 sides insertion ball bowl main body 21 of the ball bowl main body 21 that forms by forge or casting etc. in advance will be configured as in advance.
Then, shown in (b) figure of Fig. 1, make the part (being the upper end portion in the drawings) in the bulb 41 of the inside that is inserted in this ball bowl main body 21 outstanding to lean out from the first ball bowl opening portion 25 to the mode of outside (being the top in the drawings).At this moment, ball bowl main body 21 and bulb 41 are kept by not shown holding members such as anchor clamps respectively, keep discontiguous each other state thus, and a part (in the drawings for top) of keeping bulb 41 projects to outside state from the first ball bowl opening portion 25.And then, shown in (c) figure of Fig. 1, in this outstanding position, the base end part 49 of pin portion main body 45 that utilizes for example projection welding (projection welding) will form the pin portion 42 of lip part 46 is connected to bulb 41 (welding process) from the first ball bowl opening portion, 25 face down bondings.This welding position is the position of also leaning on the outer side of ball bowl main body 21 than the first ball bowl opening portion 25.
After this, to utilize slip surface 35 that bulb 41 is held in the inside (inner room 24) that ball seat 17 that the mode that can slide will be shaped in advance is assembled in ball bowl main body 21, and the nest plug 22 that will be shaped in advance is installed on holding part 32, carry out calking and make this calking fixing part 33 distortion towards the calking fixing part 33 of central side then ball bowl main body 21, the ball seat 17 that will maintain bulb 41 is thus taken in the inside that remains in ball bowl 16 with bulb 41, the dust-proof cover 19 that will be shaped in advance then is assembled between ball bowl 16 (ball bowl main body 21) and the ball stud 18 (pin portion 42), thereby finishes ball-joint 11 (assembling procedure).
As mentioned above, in an above-mentioned mode of execution, constitute following structure: with the inside of bulb 41 from the second ball bowl opening portion, 26 these ball bowl main bodys 21 of insertion of ball bowl main body 21, and the terminal side (another is distolateral) of pin portion 42 is connected to bulb 41 from the first ball bowl opening portion, 25 face down bondings of ball bowl main body 21, above-mentioned pin portion 42 side (is distolateral) endways is formed with lip part 46.
Therefore, because the lip part 46 of pin portion 42 does not run through each opening portion 25,26 by (insertion) ball bowl main body 21, be not subjected to the constraint of the radial dimension etc. of each opening portion 25,26 so can freely set the radial dimension of lip part 46.That is, for example the radial dimension D4 of lip part 46 can be set bigger than the radial dimension D3 in bulb 41.
And, owing to after this do not need to carry out lip part 46 is assembled in addition the operation of pin portion 42, so productivity is reduced, and, make its distortion owing to not needing that the first ball bowl opening portion, 25 sides of ball bowl main body 21 are carried out calking, so can make the radial dimension of the first ball bowl opening portion 25 and the torque stabilization of ball-joint 11 etc., can guarantee quality.
And, in welding process, make the part in the bulb 41 that is inserted in these ball bowl main body 21 inside project to the outside of ball bowl main body 21 from the first ball bowl opening portion 25 of ball bowl main body 21, and pin portion 42 is connected to bulb 41 from the first ball bowl opening portion, 25 face down bondings of ball bowl main body 21 in this outstanding position, thus, even if when welding the time, produced under the situation of splash, this splash can not be attached to the inside (inner room 24) of ball bowl main body 21 yet, can guarantee the quality of ball bowl 16 (ball bowl main body 21), and do not need to be used to remove the operation of splash of being attached to ball bowl main body 21 etc. yet, can further boost productivity.
Further, under the situation of the ball-joint 11 that for example is used in the stabilizer connecting rod, require sliding good.The sliding of ball-joint 11 depends on the surface roughness and the sphericity in bulb 41, wanting to have the material of hardness to a certain degree, therefore under the situation of more accurately outer circumferential face in bulb 41 being processed, as bulb 41, for example high carbon steel is suitable.On the other hand, under the situation of this ball-joint 11, the load that puts on pin portion 42 is very not big, and therefore relative with price higher high carbon steel with hardness is compared, and utilizes the relatively low low carbon steel of hardness and price just can tackle fully.Like this, the material that differs from one another by utilization forms bulb 41 and pin portion 42, can use the material that is suitable for separately to bulb 41 and pin portion 42, can improve the characteristic of ball-joint 11, and can realize cost degradation.
In addition, in an above-mentioned mode of execution, ball-joint 11 can be used in for example device of the operating the rudder arbitrary positions such as (the steering gears) of vehicle.
In addition, bulb 41 and pin portion 42 also can be made of mutually the same material, can also be any metals that is suitable for welding beyond the carbon steel for example.
