Abstract
The utility model provides a ball head pin of a stabilizing bar, which comprises a ball head and a pin shaft connected with the ball head, wherein the ball head and the pin shaft are independently fabricated and molded, a slot is formed at the upper part of the ball head and is matched with the lower end of the pin shaft, the diameter of the lower end of the pin shaft is slightly greater than that of the slot, and straight stripes are machined on the lateral surface of the lower end of the pin shaft and is parallel to the axis of the pin shaft. The ball head and the pin shaft of the ball head pin of the stabilizing bar are independently fabricated and molded, thereby achieving the effects of independent processing and large-batch fabrication. Since the diameter of the ball head is less than that of the pin shaft, the consumption of the blank material required for the fabrication of the ball head is reduced. Besides, the pin shaft is fabricated through cold extrusion-forming process, which reduces the consumption of the blank material and simplifies the fabrication procedure, thereby greatly increasing the work efficiency and reducing the production cost. Furthermore, the ball head is independently molded and has simple structure, so that during the outer surface treatment of the ball head, for example, the smoothing treatment, the method of treatment process with the machine tool is greatly simplified.
Description
Technical field
The utility model belongs to the technical field of automobile chassis structure, relates to a kind of rear stabilizer ball stud.
Background technique
In the prior art, the bearing pin and the bulb of the ball stud 1 of the rear stabilizer of conventional structure are normally integrally formed, as shown in Figure 1.In this case, because the maximum diameter of bearing pin is bigger than the diameter of bulb, need the bigger blank material of diameter 2 when therefore making, as shown in Figure 2, therefore when making bulb, the blank material of waste is many.In addition, because ball stud is integrally formed, bearing pin can not separate with bulb, and therefore when bulb was carried out surface treatment, technology difficulty was very big, especially is difficult to carry out smooth surface in the bulb minimum point and handles.For solving above-mentioned technological problems, usually adopt lower end to be processed into a plane or cavity with bulb, but this can make ball stud when rotated, the internal surface of ball seat is damaged at the outer rim place of the plane of bulb lower end or cavity easily, influence the quality and the working life of product, for example Chinese patent application number has disclosed a kind of such structure for CN200820131377.0 " ball stud ", and for example Chinese patent application number has equally also disclosed a kind of such structure for " ball stud " of CN200910098340.1 again.
The model utility content
Problem to be solved in the utility model is: provide at the problem of above-mentioned existence that a kind of required blank material is few, the simple rear stabilizer ball stud of preparation process.
The technological scheme that the utility model adopted is: a kind of rear stabilizer ball stud is provided, comprise a bulb and a bearing pin that links to each other with bulb, it is characterized in that: independent respectively making of described bulb and bearing pin is shaped, and described bulb top is provided with the slotted eye that is complementary with described bearing pin lower end.
Further, the slightly larger in diameter of described bearing pin lower end is in the diameter of the slotted eye on described bulb top, and when described bearing pin was installed in the slotted eye on described bulb top, the slotted eye inwall had bigger extruding force to the bearing pin lower end like this, described bearing pin is tightr with being connected of bulb, is difficult for throwing off.
Further, described bearing pin lower end side is processed with lines, like this when described bearing pin is installed in the slotted eye that is expressed to described bulb top, described bearing pin lower end can utilize the space between the lines to carry out slightly deformed, making is not influencing under the situation that is connected tightness of described bearing pin and bulb, bearing pin can push in the slotted eye that is installed to described bulb top with comparalive ease, and has reduced the required precision to the processing technology of bearing pin lower end and slotted eye.Preferably, described lines is the vertical bar line that parallels with described bearing pin axis, and at this moment, when described ball stud rotated, the frictional force between bearing pin lower end side outer wall and the slotted eye side inner walls had strengthened because of the existence of vertical bar line.
Compared with prior art, the utility model rear stabilizer ball stud, can independent separately processing also be made in technology working process in enormous quantities owing to its bulb and the independent making shaping of bearing pin difference; Because the diameter of bulb is less than bearing pin, therefore saved and made the required blank material of bulb, and bearing pin can adopt cold-extrusion technology to make also to have reduced required blank material and manufacturing procedure, therefore productivity is provided greatly and reduced cost of production; In addition, because bulb independently is shaped and simple shape, so bulb is when carrying out the outer surface process treating, smooth treatment for example, and lathe carries out the also simplification greatly of method of process treating.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
Embodiment: to shown in Figure 5, the rear stabilizer ball stud in the present embodiment comprises the bearing pin 3 (as shown in Figure 3) that a bulb 4 and links to each other with bulb 4 as Fig. 3, and described bulb 4 is shaped with independent respectively making of bearing pin 3.Described bulb 4 tops are provided with the slotted eye 5 (as shown in Figure 4) that is complementary with described bearing pin 3 lower ends, and the slightly larger in diameter of described bearing pin 3 lower ends is in the diameter of the slotted eye 5 on described bulb 4 tops.Described bearing pin 3 lower end side are processed with lines 6, and described lines 6 is the vertical bar lines (as shown in Figure 5) that parallel with described bearing pin 3 axis.
Claims (4)
1. a rear stabilizer ball stud comprises a bulb and a bearing pin that links to each other with bulb, it is characterized in that: independent respectively making of described bulb and bearing pin is shaped, and described bulb top is provided with the slotted eye that is complementary with described bearing pin lower end.
