Therefore, after the front pillar assembly 11 and the connecting seat 12 are assembled, the connecting sleeve 14 is located between the first nut 13 and the second nut. The inner connecting sleeve 14 is a stamping part, and the contact part between the inner connecting sleeve 14 and the connecting seat 12 is vulcanized rubber, which can avoid the abnormal noise problem caused by the relative movement of the inner connecting sleeve 14 and the connecting seat 12 during the movement of the front pillar assembly 11.

[0026] Preferably, the front pillar assembly 11 is integrally formed by a metal frame and rubber vulcanization, and the outer surface of the front pillar assembly 11 in contact with the connecting seat 12 is made of rubber material. Self-lubricating material (such as paraffin, etc.) is added during the production process of the rubber material to avoid abnormal noise caused by friction between rubber and metal during the movement of the front pillar assembly 11.

[0027] In the present embodiment, the vehicle suspension system passes the piston rod 111 of the front pillar assembly 11 through the through hole 102 of the connecting seat 12, and is fastened to the piston rod 111 through a first nut 13, thereby eliminating the structural design of riveting three bolts on the metal frame in the prior art, which not only reduces the overall size of the connecting seat 12 and reduces the installation space, but also the front pillar assembly 11 can be connected to the connecting seat 12 of the vehicle body through the cooperation of the piston rod 111 and the first nut 13, and only one first nut 13 is required to achieve this.
