DESCRIPTION

Convoluted Air Spring

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.

Convoluted air springs are made with single, double or triple bellows and are used in a variety of applications and suspensions. These air bags are found on all types of trucks, trailers, and industrial applications. They are available with a wide variety of load capacities, ride heights and mounting top and bottom plates.

Air ride uses a variety of valves, air lines and air-spring bags in place of steel suspension. The flexible air-spring bags are made from a woven and rubber-like material. The air supplied to the air-ride suspension uses the same air compressor and air reservoir as a truck’s braking system. The supplied air pressurizes the air-spring bags, creating a spring-like motion that raises the chassis from the axle.

Spring suspensions use semi-elliptic leaf springs to cushion a load from road shock. As one of the most commonly used suspensions, spring ride consists of several layers of flexible steel strips referred to as a “leaf pack.” The strips are joined together to act as a single unit. The long and narrow, arch-shaped plates are attached to the frame of a trailer, resting above the trailer's axle.
