What are the applications of rubber airbags in the automotive field?

Answer:

HoseThe pipeline is one of the main parts of automobile essential, including water, steam, oil pipe, air conditioning pipe and oil pipe, gas pipe and hose turbocharging. Because of the limited size of the car, the pipes connecting the various equipment must be bent many times, and the bending resistance, flexibility and flexibility of the rubber are very good. Therefore, most of the tubes used in the automobile are rubber hoses. Such as lubricating oil is widely used in ACM and AEM made the oil radiator radiator hose and hose, with excellent heat resistance; the air delivery pipe and the air inlet pipe must have good fatigue resistance, weather resistance, shock resistance, vacuum collapse and oil resistance, various kinds of elastomer (such as CR, NBR/PVC, EPDM, CM, ACM) and thermoplastic elastomer (such as polyester, polypropylene blends and EPDM body) was selected for the purpose.
Conveyor beltThe most common belt in a car is a synchronous belt used to drive the crankshaft cam synchronously. Compared with the metal chain, the synchronous belt can effectively reduce the contact noise with the sprocket, and does not need lubrication, and has the characteristics of light weight. At the same time, due to its flexibility, it can also be applied to multi axle drive. In Japan, more than 70% of cars use synchronous belts, while in Europe it is as high as 80%. Previously, rubber synchronous belt has been covered with neoprene (CR). Nowadays, a large number of studies have found that hydrogenated butyl rubber (HNBR) has better performance, so more applications have been obtained in automobile synchronous belt. HNBR has superior properties than CR, complex modulus, good stability and low temperature performance, heat resistance and ozone resistance, excellent flexing resistance and good oil resistance in a wide temperature range. In the test of tape function, hydrogenated rubber (HNBR), compared with chloroprene rubber (CR) covering rubber, has a heat resistance level of 40 DEG C at the same operation time. At the same time, the life of HNBR is 2 times that of CR.
Sealing system is mainly used to prevent leakage of liquid or other materials, including O ring, rotary shaft oil seal, sealing strip, dust cover, flat gasket and so on. Seals are sometimes made of metal, plastic, or fabric, but more of them are made of rubber. In the early 80s of last century, the United States successfully developed PTFE composite oil seal, successfully solved the problem of engine oil leakage, water leakage, and at the same time greatly improved the technical performance of the car. When the engine and transmission system uses oil series lubricants, the sealing material is usually made of butyl rubber (NBR), acrylic rubber (ACM), silicone rubber (VMQ) or fluorine rubber (FPM).Engine oil requires long life, low viscosity (oil saving), smooth lubrication at high temperature, so engine oil usually contains a variety of additives. Long time soaking HNBR, FPM and ACM at high temperature in an additive containing oil, can maintain high compressive strength. The hydrogenation of chloroprene rubber (HNBR) in which several rubber additives on resistance is the best, at the same time by Ding Xiangjiao (HNBR) heat resistance, oil resistance, aging resistance, is rubber products, currently used in high performance auto parts have been widely. For a long time, the automotive industry has been using NBR and cork rubber to make gaskets for engines, but now uses ACM and VMQ as the main material to satisfy the requirements of heat resistance, sealing capacity and compression durability.The fuel pump diaphragm is a typical fuel pump structure in the carburetor system. The diaphragm has to withstand the thermal impact of the engine and therefore requires not only good durability in the gasoline but also high heat resistance. Because of the need for oxidation resistant gasoline, NBR, HNBR and FPM are available for shock absorbers, insulators, and oil seals in the case of seals. As to which material to choose, the temperature depends on the specific temperature.
In automotive shock absorber products, suspension, shock absorbers, airbags, etc. are included. High performance liquid filled engine pad and axle sleeve are the representative achievements in the development of new automotive rubber products in recent years. The high function liquid filled engine pad and shaft sleeve are made of rubber elastomer as a fluid sealing film, and the rubber spring deforms when it vibrates so as to act as a buffer. Automobile safety airbag is made of rubber and rubber started to develop in 1970s, 90s new product to obtain a composite application, now not only in the driver's seat, but also installed in gallery assistant.
