It is enough that the scope of the utility model is completely communicated to those skilled in the art.
With reference to Fig. 2 and Fig. 3, the utility model embodiment provides a kind of 1 assembly of lower control arm, including：
Lower control arm 1 is provided with an installation through the lower control arm 1 with respect to two end faces on the lower control arm 1
Hole 11；
Ball pin 2, including：One end of ball pin ontology 21 and ball pin shell 22, the ball pin ontology 21 is pressed in the ball pin shell
In 22, one end of the ball pin shell 22 is exceptionally exposed to the lower control arm 1, and the ball pin shell across 11 rear portion of the mounting hole
It is interference fitted between 22 and the mounting hole 11；
Clamp spring 3, fixing sleeve are exposed to set on the ball pin shell 22 on the part of the lower control arm 1.
Wherein, clamp spring 3 can be by welding fixed on ball pin shell 22.
In the utility model embodiment, 1 assembly of above-mentioned lower control arm includes mainly following steps in assembly：
Step 1, one end of the ball pin of molding assembly 2 is pressed into the mounting hole 11 of lower control arm 1 so that ball pin 2
One end is exceptionally exposed to lower control arm 1 across 11 rear portion of mounting hole；
Step 2, clamp spring 3 ball pin shell 22 is sheathed on to expose on the part of lower control arm 1.
In the utility model embodiment, by way of being interference fitted between ball pin shell 22 and mounting hole 11, when mounted,
