in order to avoid the problems that the support bearing and the front support upper support are not assembled in place (skew or gap) and the support bearing upper cover is cracked and the like caused by poor control of fit interference during press assembly, an assembly component is arranged to replace the existing support bearing upper raceway and support bearing upper cover. The assembly component comprises a base 200 sleeved on the shock absorber 100 and an outer framework 300 arranged above the base 200, wherein the base 200 and the outer framework 300 are all workpieces which are circumferentially arranged on the shock absorber 100. In order to fix the base 200 and the exoskeleton 300 into a whole, barbs 320 are provided at the bottom of the exoskeleton 300 toward the exoskeleton 300, and grooves matched with the barbs 320 are provided at the exoskeleton 300 toward the base 200, and the base 200 is assembled by clamping the grooves on the barbs 320. The outer skeleton 300 replaces the traditional upper roller path and upper cover of the pillar bearing, and solves the problems of abnormal noise and part failure of the front pillar assembly caused in the press-fitting process by designing the barbs 320 and the grooves to cancel the press-fitting process of the original upper bracket of the front pillar and the pillar bearing.
Further, a bottom plate 310 is disposed between the outer frame 300 and the base 200, and the bottom plate 310 is an L-shaped bracket.
