Classification of air springs
According to performance and characteristics, it is also known as:
rubber air stroke regulator, rubber air vibration isolator, two
names, rubber air springs are divided into three categories
according to shape: capsule type, membrane type and sleeve type.
According to the sealing structure, it is divided into four
categories: pressure self-sealing type, rim clamping type, hoop
sealing type and hybrid type. The load of the rubber air spring is
mainly borne by the cord, and the number of layers of the cord is
mainly composed of 2 layers. The product is required to consist of
4 layers of cord. The inner layer of rubber is mainly used for
sealing, and the outer layer of rubber is not only for sealing, but
also for protection.
The end structure of the existing curved bag type rubber air spring
can be divided into three categories according to the connection
method: one is the fixed flange connection type, and the edge size
of the two ends of the air spring is equal to or slightly smaller
than the maximum outer diameter of the curved bag. Smaller, after
drilling a few holes, use flange rings and end plates to fasten the
connection; the other type is the looper flange connection type,
the edge size of both ends of the air spring is much smaller than
the maximum outer diameter of the curved bag, and no drilling is
required. , use a special flange ring and a common end plate to
fasten the connection; the third type is self-sealing type, no
flange connection is required, the end plate is pressed into the
end plate, and the compressed air is filled to seal itself.
The flange sealing forms of the end of the rubber air spring and
the connecting plate are: LHF type, JBF type, GF type, HF type and
ZF type.
