A rigid axle is a type of wheel suspension that is used in many vehicles. In a rigid axle, the two wheels are connected to each other on a rigid axle and therefore move up and down together. In contrast, independent suspensions have a separate axle on each wheel, which can be moved up and down independently of each other.
Special vehicle with rigid axle
The rigid axle is a particularly typical wheel suspension for special vehicles, as it is often used in vehicles that move on difficult terrain, such as off-road vehicles, off-road or armored vehicles for the military. Special vehicles with rigid axles also often include fire engines and ambulances. Due to the rigid connection between the wheels, the rigid axle offers these vehicles greater stability and robustness. A rigid axle is also frequently used on trucks and trailers, as it enables a higher load capacity than an independent wheel suspension.
