Scania Truck Cab Air Spring 1908097 Front Suspension Air Shock Absorber 1923645

A truck cab air spring is an elastic element installed between the truck cab and chassis frame. Filled with compressed air, it utilizes the compressibility of air to provide shock absorption, cushioning, and support. It is a core component for improving ride comfort in modern trucks, replacing or supplementing traditional steel coil springs or rubber pads.

A typical cab air spring typically consists of the following components:

• Airbag: Made of a high-strength, fatigue-resistant rubber cord layer, it seals the compressed air and absorbs vibrations through its deformation.
• Upper Cover and Lower Base (Piston): Metal components that secure the air spring to the cab and chassis frame. The shape of the lower base is typically carefully designed to optimize the airbag's deformation curve and elastic properties.
• Additional Components: These may include a height control valve, air lines, and an air reservoir to automatically adjust the airbag's height and pressure.

Its operating principle is similar to an adjustable "air cushion."

• Cushioning and Shock Absorption: When a truck travels over bumpy roads, impacts from the wheels are transmitted through the chassis to the air spring. The compressed air within the airbag is further compressed or expanded, absorbing and damping the impact energy, preventing it from being directly transmitted to the cab.
• Height Hold: The system automatically adjusts the height via a connected height control valve. When the cab load changes (for example, when the driver gets on or off the vehicle) or the vehicle posture changes, the control valve will inflate or deflate the airbag to keep the cab at a preset, stable height.
