Patent number: 9784332Abstract: Disclosed herein is a novel gas permeable internal floating piston specifically designed for installation in the multiple stage air shock whereby the multiple stage air shock is covered in prior patent applications. The multiple stage air shock includes a mixture of oil and gas whereby the mixture provides the shock with emulsion dampening properties. The gas permeable internal floating piston operates by separating the oil from the gas thereby improving the dampening properties of the shock. The permeability of the internal floating piston is based on a membrane that allows the gas but not the oil to pass through the structure of the internal floating piston. The mechanism of the permeability is governed by the creation of a pressure differential across the structure of the internal floating piston, the creation effected with a spring. The membrane features a slow rate of permeation thereby ensuring that the internal floating piston moves in conjunction with the shaft during the operation of the shock.Type: GrantFiled: November 12, 2015Date of Patent: October 10, 2017Inventor: Ronald Scott Bandy

Patent number: 9784329Abstract: The present invention discloses a brake drum comprising: a brake drum body, which comprises a mounting portion for connecting a wheel, a braking portion for engagement with a brake shoe, and a transitional connecting portion disposed between the mounting portion and the braking portion; a hoop device is tightly mounted to the outer peripheral surface of the brake portion. The hoop device adopts a plurality of split-type hoop ferrules, or one unibody hollowed-out hoop case. The hoop device tightly mounted to the outer peripheral surface of the brake portion can not only effectively restrain the radial expansion deformation, thereby improving the fatigue resistance of the brake drum body, but also applies a clasp force to the brake drum body, thereby avoiding the danger of burst and flying out of the brake drum body, which greatly improves service life and safety.Type: GrantFiled: January 6, 2016Date of Patent: October 10, 2017Assignee: SHANDONG HAOXIN MACHINERY CO., LTD.Inventors: Guangming Pu, Jixian Lv
