Whether loaded or unloaded, the AXIONIC swing axle performs several functions that ensure safe and comfortable handling: when loaded, the weight is optimally distributed over both axles, resulting in the best possible driving characteristics. Dynamic balancing movements ensure consistent ground contact and prevent the trailer from bouncing, even on roads in poor condition. This gives the Trailer optimum driving stability. Uniform contact pressure on all four wheels prevents individual wheels from locking when braking, thus ensuring particularly effective braking behavior. The swing axle allows the trailer to be driven with a slightly higher coupling on the towing vehicle, so that there is no need for height compensation on the drawbar. The swing axle compensates for dynamic forces on the coupling and ensures a constant drawbar load as far as possible. This increases driving comfort, protects the stability of the trailer combination and protects the overrun coupling.
