| Zusammenfassung: | A steering centering/damping mechanism for a steerable heavy-duty vehicle axle/suspension system which includes a mechanically operated structure that provides a positive steering centering force to the axle/suspension system at a zero steer angle. The mechanically operated structure of the steering centering/damping mechanism also provides a positive steering centering force that increases in intensity as the steer angle of the axle/suspension system increases. In an embodiment of the steering centering/damping mechanism, the mechanically operated structure is a flat spring integrated into one or more steering assemblies of the axle/suspension system. The flat spring is in a pre-loaded condition at a zero steer angle to provide the positive steering centering force to the axle/suspension system at the zero steer angle, and is increasingly elastically deformed with increasing steer angles to provide the positive steering centering force which increases in intensity as the steer angle of the axle/suspension system increases. |
