These specialized suspension components are pneumatic devices designed to provide an extended range of vertical movement. As an example, consider an off-road vehicle traversing uneven terrain; these devices allow the suspension to articulate significantly, maintaining tire contact and improving overall stability and control.
The incorporation of such components can substantially improve a vehicle’s off-road capabilities by maximizing wheel travel and dampening impact forces. Historically, they have been favored in applications where substantial ground clearance and articulation are required, evolving from simpler pneumatic systems to more sophisticated, adjustable solutions.
