High-strength disk

The invention discloses a high-strength disk which comprises a disk body in a disc type structure, wherein the disk body comprises a filling rubber layer; the filling rubber layer is wrapped with a wrapping rubber layer; a mounting hole penetrating through the filling rubber layer and the wrapping rubber layer and used for assembling a barbell rod is formed in the center of the disk body; a shaft sleeve connected with the barbell rod in an assembly manner and combined with the wrapping rubber layer is arranged in the mounting hole; and a fixing component for improving connection strength between the shaft sleeve and the wrapping rubber layer is arranged on the shaft sleeve. Through experiments, the drop strength of the full rubber disk produced by the patented technology is improved to 20000 times, and the adhesion strength between a metal core shaft and rubber is improved to 4000kg from 1000kg. The disk is reasonable in structure, firm, durable and very good in shock absorption effect, has no intensive collision impact between metal parts, low noise and an excellent landing shock absorption effect, does not damage the ground, and has very broad application prospects.
