The invention discloses a damping piston which comprises a piston outer body and an upper end surface. The upper end surface is fixedly connected to the top end of the piston outer body, and comprisesan outer ring body, a first inner ring body, a second inner ring body and a built-in plate; the first inner ring body is fixedly connected to the side surface of the outer ring body; the second innerring body is fixedly connected to one side, far away from the outer ring body, of the first inner ring body; the built-in plate is fixedly connected to one side, far away from the first inner ring body, of the second inner ring body; and four small annular lugs are fixedly connected to the inner side of the outer ring body, and adopts center points of the upper end surfaces as center points. Thedamping piston is processed through aluminum alloy casting so as to be convenient to process and form, the cost is reduced, the damping piston is suitable for mass production, and the produced pistoncan bear larger oil pressure impact and has better impact strength and abrasion resistance, so that the service life of a damper during movement is prolonged.
