When the automobile runs on a road surface, the automobile is subjected to vibration and impact due to the change of the ground, and part of the force of the impact is absorbed by the tire, but most of the force is absorbed by a suspension device between the tire and the automobile body. The suspension mainly functions to transmit force and torque acting between the wheels and the vehicle frame, and buffers impact force transmitted to the vehicle frame or the vehicle body from an uneven road surface, and attenuates vibration caused by the impact force so as to ensure that the vehicle can run smoothly.

The fixing plate 1 is in an axisymmetric structure, and the mounting holes 10 are positioned on the symmetric axis of the fixing plate 1; four fixed orifices 11 also are the symmetry and set up on fixed plate 1, make fixed plate 1 install on the car axle stability high.

As shown in fig. 2 and 4, the pin shaft 2, which is perpendicular to the fixing plate 1, includes a positioning section 20, a supporting section 21 and a connecting section 22, which are connected in sequence; the positioning section 20 is arranged in the mounting hole 10, and the connecting section 22 is provided with an external thread; the diameter of the supporting section 21 is larger than that of the positioning section 20, and the diameter of the supporting section 21 is larger than that of the connecting section 22; dividing the actual assembly requirement of the installation of the pin shaft 2 into a plurality of sections, wherein the positioning section 20 is used for integrally positioning the pin shaft 2, and the positioning section 20 needs to be subjected to finish machining so as to determine the position of the pin shaft 2 relative to the fixing plate 1; the supporting section 21 is mainly used for connecting the reinforcing ribs 3, the diameter of the supporting section 21 is larger than that of the limiting circular truncated cone 212, so that the processing is also needed, but the precision requirement of the supporting section 21 is not high as that of the positioning section 20; the limiting round platform 212 is mainly used for blocking the rubber bushing when the stabilizer bar is assembled, and the rubber bushing is prevented from being separated from the connecting section 22, and the limiting round platform 212 on the pin shaft 2 is the section with the largest diameter on the pin shaft 2, so that the limiting round platform 212 can be processed or not processed, and the outer surface of the direct limiting round platform 212 is the initial surface of a bar blank.

Specifically, as shown in fig. 4, the processing of the pin 2 is implemented by the following method: taking a bar material with the same diameter as the limiting circular truncated cone 212, turning along one end to form a supporting section 21, and performing finish machining on one end, far away from the limiting circular truncated cone 212, of the supporting section 21 to form a positioning section 20; and turning the bar material along the other end to form the connecting section 22, tapping one end of the connecting section 22 to form an external thread, namely dividing the connecting section 22 into a polished rod 220 and a threaded rod 221, and finally chamfering the threaded rod 221, the polished rod 220 and the positioning section 20.
