Abstract
An aircraft undercarriage having a sliding rod slidably mounted in a strut-leg, and a scissors linkage () having one branch () hinged to the strut-leg or to a turning element of a control for steering the sliding rod mounted to turn in the strut-leg, and one branch () hinged to the sliding rod, the branches being hinged to each other by a pivot pin (), the undercarriage being fitted with a shimmy-attenuator device () placed on the pivot pin of the shimmy-attenuator, the attenuator device including threshold resilient return means generating a force returning the branches towards a rest position, and at least damping means generating a damping force when the branches move axially along the pivot pin. The attenuator device comprises two modules () placed on either side of the scissors linkage in order to co-operate with the pivot pin, each of the modules performing at least one of the damping function and the threshold resilient return function.
