DESCRIPTION
Air springs for driver’s seats ensure a more ergonomic and
comfortable working situation, while at the same time helping to
ward off driver fatigue or health impairment. Air suspension of the
cab has a major impact on ride comfort. These air springs are
designed as sleeve-type rolling lobe air springs and take the form
of a two- or four-point suspension between the driver’s cab and the
chassis frame.
In buses, air springs deliver safety and ride comfort. Thanks to
the self-leveling system, the vehicle maintains the same level,
which means that the boarding level also remains unchanged,
regardless of the number of passengers. With additional control
functions, the vehicle body can “kneel”, which aids entry and
alighting. This generally entails fitting two air springs to the
front axle and trailing axle and four on the rear or drive axles.
As air is directed into air springs, the bladders allow them to
expand in a linear fashion, which permits them to be used as
force-developing actuators, like pneumatic cylinders, and as such,
rod attachments are available to mimic the function of them. Most
often, however, an air actuator is simply two end plates connected
by a bladder, and as they’re pressurized, force pushes the plates
away from each other. As linear actuators, they can provide up to
35 tons of force, making them useful in various press applications,
such as a forming press or small stamping press. Air actuators are
also excellent for constant force applications, such as pulley
tensioners or drum roller compression devices. All air springs are
single-acting, unless they are coupled together so one extends
while the other retracts.
