The connecting rod portion 1 may include a rod body 11, and both axial ends of the rod body 11 are connected with the flat portions 12, respectively, that is, both axial ends of the rod body 11 may be connected with one ball pin seat 2 through one flat portion 12, respectively.
As shown in fig. 1, the thickness (i.e., the dimension in the top-bottom direction) of the flat portion 12 may be smaller than the thickness of the rod body 11, so that the flat portion 12 may avoid the problem of machining interference at the joint of the ball pin seat 2 and the connecting rod portion 1, avoid developing a special forming tool, and save development cost.
According to the stabilizer bar connecting rod 100 of the embodiment of the invention, the flat parts 12 are respectively arranged at the two axial ends of the rod body 11, so that the problem of machining interference at the joint of the ball pin seat 2 and the connecting rod part 1 is avoided, the development of a special forming cutter is avoided, and the development cost is saved. Meanwhile, the metal streamline of the blank of the ball pin seat 2 can be prevented from being folded and bent when the bar stock is forged and formed, the metal streamline can move along the flat part 12 automatically, and the tensile strength of the workpiece made of the same material and subjected to the same heat treatment is increased.
In addition, the flat portion 12 enables the metal flow line during forging to move faster along the inner cavity of the die, and the stabilizer link 100 can be forged and formed with a smaller forging pressure, so that the service life of the forging die is prolonged, and the energy consumption is reduced.
Specifically, as shown in FIG. 1, the thickness of the link portion 1 may be X, the thickness of the flat portion 12 may be Y, and 0.65 X.ltoreq.Y.ltoreq.0.85X may be satisfied between X and Y. Therefore, the flat part 12 at the joint of the rod body 11 and the ball pin seat 2 can be ensured to have proper thickness, so that the problem of machining interference at the joint of the ball pin seat 2 and the connecting rod part 1 is fully avoided, and the whole stabilizer connecting rod 100 is easier to machine.
Specifically, as shown in fig. 2, two oppositely disposed side edges 121 may be disposed between the connecting end of the link portion 1 and the connecting end of the ball pin seat 2 of the flat portion 12, and both side edges 121 may be tangent to the outer circumferential surface of the ball pin seat 2. Therefore, the connecting area between the link portion 1 and the ball pin boss 2 can be increased, fatigue-resistant cracking between the link portion 1 and the ball pin boss 2 can be prevented, and the stabilizer link 100 has higher overall strength.
Specifically, as shown in fig. 2, the tangent points 122 at which the side surfaces of the flat portion 12 are tangent to the outer peripheral surface of the ball pin holder 2 are two in total, and the included angle α between the two radii of the two tangent points 122 in the ball pin holder 2 can satisfy 140 ° α or more and 160 ° or less. Therefore, the connecting area of the connecting rod part 1 and the ball pin base 2 can be further increased, the fatigue endurance cracking between the connecting rod part 1 and the ball pin base 2 can be prevented, and the overall strength of the stabilizer link 100 is higher.
Specifically, as shown in fig. 1, the flattened portion 12 may be spaced apart from both the top end of the ball housing 2 and the bottom end of the ball housing 2, respectively. That is, the flat portion 12 can be fixed at the middle position of the ball pin boss 2 in the top-bottom direction, whereby the problem of machining interference at the joint of the ball pin boss 2 and the link portion 1 can be further avoided.
Specifically, as shown in fig. 1, a smooth transition portion 13 may be connected between the rod body 11 and the flat portion 12, a top surface of the smooth transition portion 13 may include a top slope section 131 and a pressing plane section 132, the pressing plane section 132 may be connected to the rod body 11, the top slope section 131 may be connected between the pressing plane section 132 and a top end of the flat section, and the pressing plane section 132 may be flush with the top surface of the rod body 11.
In order to facilitate the forging of the ball pin seat 2, the connecting rod portion 1 needs to be clamped and fixed, the lower pressing portion pressed on the bottom surface of the connecting rod portion 1 can be pressed on the bottom surface of the rod body 11, and the upper pressing portion pressed on the top surface of the connecting rod portion 1 can be pressed on the pressing plane sections 132 near the ball pin seat 2 at the two ends of the connecting rod portion 1, so as to further ensure that the ball pin seat 2 is kept fixed during the forging.
As shown in fig. 1, the included angle between the pressing plane section 132 and the top inclined plane section 131 may be β, the bottom surface of the smooth transition portion 13 may include a bottom inclined plane section 133, and the included angle between the bottom inclined plane section 133 and the bottom surface of the rod body 11 may be γ.
More specifically, beta and gamma can satisfy that beta is more than or equal to 6 degrees and less than or equal to 10 degrees, and gamma is more than or equal to 2 degrees and less than or equal to 5 degrees. Therefore, the top and the bottom of the smooth transition part 13 can be ensured to be transited more slowly, the metal streamline of the blank of the ball pin seat 2 can be further prevented from being folded and bent when the bar stock is forged and formed, the metal streamline can move along the flat structure automatically, and the tensile strength of workpieces made of the same materials and subjected to the same heat treatment is increased.
