Rubber air spring is a curved capsule composed of the rubber cable, paste, pneumatic, pneumatic bellows, commonly known as the tiger skin bag, etc.. The two ends of the capsule are connected by two pieces of steel plate to form a compressed air chamber. The rubber and the wire itself do not provide the load bearing capacity, but are completed by the compressed air filled into the capsule. The number of its curved sac is usually 1~3, but it can also be designed to make 4 or 5 parts as required. It can also superimpose two air springs under certain conditions.
  According to the performance and characteristics, the rubber air spring is called the rubber air stroke regulator, the rubber air isolation body, and the two product names. The end structure of the existing crumb rubber air spring,According to the way of connection, it can be divided into three categories:A fixed flange type air spring, both ends of the curved edge size and smaller or equal to the maximum outer diameter of sac, drill holes after the flange ring and the end plate is fixedly connected; the other one is a loop type flange connection type, both ends of the air spring edge size than the maximum diameter of bellows is much smaller, no holes, with a special flange ring and a common end plate fastening; third kinds of self sealing type, without flanges, pressed into the end plate, the compressed air is filled into the self sealing.
  The end of the rubber air spring and the flange of the connecting plate are sealed in the form of five types: LHF, JBF, GF, HF and ZF.
