Rubber top mount of shock absorber

The invention relates to a rubber top mount of a shock absorber. The rubber top mount comprises an upper frame, a lower frame and a rubber body positioned between the upper frame and the lower frame,wherein a rubber layer is vulcanized on the lower surface of the lower frame; the lower frame is provided with an arc matched with a thrust bearing; the upper frame and the lower frame are connected together by welding along the circumference of the contact part between the upper frame and the lower frame; the upper frame and the lower frame are both sleeved on a nut; and the nut is sleeved on a piston rod. The rubber top mount of the shock absorber has the advantages of eliminating the gap between metal pieces due to the manufacturing precision, eliminating noise, solving the risk of loosening of the nut during the using process, allowing the bearing to be stressed uniformly, reducing the stress on the bearing, preventing the bearing from being damaged, improving the service life of the bearing, reducing the stre
