The Influence of Steered Axles on the Dynamic Stability of Heavy Vehicles

The use of steered rear axles on heavy vehicles has increased. They occur both on trailing units and on trailers. The extent to which the dynamic stability is affected depends on the location of the steered axles and on the steering principle. The effect on the dynamic stability was investigated for different applications and steering principles. The analyses were performed with both linear and non-linear models and also with experimental methods.
