About Air Spring Actuator
According to the structure of the air bag, the air spring can be
divided into three types: bag type, membrane type and composite
type.
Bladder air spring
The bladder-type air spring consists of a rubber bladder with cords
and compressed air enclosed in it. The inner layer of the airbag is
made of air-tight rubber, while the outer layer is made of
oil-resistant rubber. Airbags are generally made of two
convolutions, but there are also single convolution or three or
four convolutions. The more the number of convolutions, the better
the elasticity. There is a steel waist ring/belt loop/ girdle hoop
between the convolutions, so that the middle part will not expand
radially and prevent the two sections from rubbing against each
other. The upper and lower covers of the airbag seal the airbag.
Membrane Air Spring
The airtight air bag of the membrane air spring is composed of a
rubber diaphragm and a metal pressing part. Compared with the
bladder type, its elastic characteristic curve is ideal, because
its stiffness is smaller than that of the bladder type, and the
natural vibration frequency of the body is lower; and the size is
smaller, which is easy to arrange on the car, so it is mostly used
in cars.
Composite air spring
From a structural point of view, the composite air spring is a type
between the capsule type and the membrane type. It combines the
advantages of the above two types of air springs and has a lower
spring stiffness, but the manufacturing process is complicated.
