The usefulness of air springs is associated to suspension
systems in heavy-duty vehicles. Why? They take advantage of the compressed air needed
for supporting the vehicle braking systems. In the recent past, air springs
have offered a two-fold benefit over coil-springs. It has been noticed that
with the implementation of these special springs, extra comfort is guaranteed.
With the change in air pressure present within the spring, changes are
experienced in spring rate, and finally the ride quality.
Industrial Applications of Air
Springs
It should be known that, the benefit of air actuators or
springs hasn’t been unnoticed across the industrial machine sector. Air
actuators are utilized as shock absorbers, vibration isolators, linear
actuators and tensioners. With this application field, the air springs market has indeed seen a major growth in the past few
years.
The industrial usage of air springs is primarily to absorb
shock in material handling tasks, for example a saw mill in which logs are released
over processing stations. In addition, air springs act as the finest vibration
isolators, making them useful to be used in a commercial laundry machine or
vibrating hopper.
Types of Air Springs
At present, the two prime versions of air spring available
in the market are the convoluted bellow and rolling lobe (or reversible
sleeve). Talking about the rolling lobe air spring, it makes use of a solo
rubber bladder that folds inward and even rolls outward. This motion depends on
the distance and direction in which it is moved. On the other hand, the
convoluted bellow air spring comprises of three shorter bellows, including the
multiple units armored using a girdle hoop. It is interesting to know that, convoluted
air springs are known to produce ten times the force as compared to a rolling
lobe air spring.
In case you are planning to invest in any of the air spring
varieties, make sure to consult with an expert beforehand.
