The main role of air spring hoop:

The benefits of this design are mainly the following:

1. Improve the efficiency of inflation

From one song to two songs, to three songs, to four songs... It is not difficult to imagine that the more hoops, the more effective it is to reduce the internal space of the skin. Increasing the aeration efficiency of the air spring may not be obvious in the common two-curved, three-curved air springs. But if it is more than half a meter in diameter or some air springs that need to adjust the internal air pressure frequently, you can clearly feel the wonder of this design.

2. Reduce the use of work space

During the use of the air spring, the air spring always shoulders the buffer, the weight bearing, and the lifting effect are all “heavy and heavy”. In the absence of the hoop, the air is compressed from the moment of the air spring, and the internal compressed air Under the pressure of the outside world, the middle part of the airbag rapidly expands because the upper and lower ends are sealed and fixed by the end cover. The process of expansion may cause the wear and tear of the skin, piercing, causing damage to the skin. The design of the hoop can improve the adaptability of the air spring to the factory site to a certain extent. At the same time, the compact setting and the reduction of space waste are more suitable. Design requirements.
