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.
