What are the advantages of air springs?

1) The air spring has excellent nonlinear hard characteristics, which can effectively limit the amplitude, avoid resonance, and prevent impact. The nonlinear characteristic curve of the air spring can be ideally designed according to actual needs, so that it behaves with a lower stiffness value near the rated load.
2) Since the medium used by the air spring is mainly air, it is easy to implement active control.
3) The stiffness k of the air spring changes with the load P, so under different loads, the natural frequency of the vibration isolation system is almost unchanged, and the vibration isolation effect is almost unchanged.
4) The stiffness of the air spring is adjustable, and the stiffness of the system can be changed by changing the volume of the air chamber or the inner cavity pressure. No matter how much the load is, the air pressure can be changed as needed to adjust the air spring stiffness, or the internal volume of the auxiliary air chamber can be increased to reduce the stiffness.
5) For the same size air spring, when the internal pressure changes, different bearing capacities can be obtained. This allows the same air spring to adapt to a variety of load requirements, so it is economical. While bearing vertical load, air spring can also bear certain lateral load and transmit torque.
6) Increasing the total volume of the air spring can reduce the natural frequency of the vibration isolation system, which is a unique advantage of the air spring. The volume of the air spring body cannot be too large because the size of the structure space is limited to a certain extent. In order to reduce the natural frequency of the vibration isolation system, an auxiliary air chamber can be set up, and the auxiliary air chamber can be arranged away from the air spring. The volume of the auxiliary air chamber is increased, that is, the total volume of the air spring is increased, and the natural frequency of the air spring vibration isolation system is reduced.
7) The air spring can use the height control valve system to keep the working height of the air spring basically unchanged under different loads. Similarly, through the action of the height control valve, the air spring can have different heights under a certain load, so it can adapt to various structural requirements.
8) The air spring can absorb high frequency vibration and has excellent sound insulation performance.
Air springs are mainly composed of rubber bladders and air. During the vibration process, the rubber bladder has little internal friction due to expansion and warping, so it is difficult to transmit high-frequency vibration. Air and rubber do not transmit sound easily, so they have good sound insulation properties. The steel spring is easy to transmit high-frequency vibration, but also easy to transmit sound.
9) If an orifice is set between the main air chamber and the auxiliary air chamber of the air spring, when the air spring vibrates and deforms, there will be a pressure difference between the main and auxiliary air chambers, and the air flows through the orifice and absorbs a part of the energy due to resistance. , so it has a damping effect. A suitable orifice diameter can improve the damping characteristics of the vibration isolation system and effectively suppress the resonance amplitude.
10) The air spring is light in weight. In addition to the rubber bladder and almost weightless air, its body is the upper and lower covers, so it is much lighter than the steel spring.

Guangzhou Guomat Air Spring Co., Ltd. is located in Guangzhou, about 15min’s drive from Baiyun Airport. Our mainly products are air spring, rubber bellows, air suspension spring, air suspension compressor and refitted suspension system. They are widely used in bus, truck, cabin, vehicles’ seat, luxurious car and industrial machine field.

GUOMAT Factory gate：

Established in 2008, Our company covers 20,000㎡ and is located in Taihe Town Baiyun District. With the rapid development of our company, we are equipped with modernized workshop and advanced rubber air springs equipments now. We are the first company who started air spring business and has become one of the largest air spring manufacturing bases in China.

In 2017, we launched a collaboration with High Tech of US customers to customize the products of our customers and the logo of our customers. Every year, there are about 10,000 orders. In continuous cooperation, the products meet the international inspection standard ISO/TS16949:2009, and the customers are very satisfied with the products produced. This is our high recognition from American customers and also gives us Great motivation.

In 2018, we started cooperation with German GmbH, mainly industrial air springs, which are suitable for industrial equipment. We have successfully developed and produced the natural air-seal of the skin to reach the 700mm flanged air spring, the customer's annual demand is a few hundred.

With the development of business and demand for customers, our company introduced business with TomLog Corporation in 2010, our strategic cooperative partner in Taiwan. Then we developed air compressor program and air spring related business, in 2015, America Goodyear Corporation met with the transfer of shares in the North American plant, our company was granted with sale agent for air springs in China, providing more choice for our customers. Our company adopts the most advanced domestic air spring processing equipment and international production technology. Combined with unique production process, our company strictly execute international standards for production and spare no efforts to create the world-class products. We will endeavor to make air spring widely used at home and abroad, and let more and more customers to enjoy the best damping effect.
