11. A method for manufacturing an elastic link, the elastic link comprising:
a first sleeve, comprising a first elastic body, a first inner armature surrounded by the first elastic body, and a first outer armature surrounding the first elastic body, and
a second sleeve, comprising a second elastic body, a second inner armature surrounded by the second elastic body, and a second outer armature surrounding the second elastic body,
the first elastic body and the second elastic body presenting different elastic behaviors, wherein a damping of the first elastic body in a first radial direction relative to a link axis is greater than a damping of the second elastic body in the first radial direction relative to the link axis, and a resilience of the second elastic body in a second radial direction relative to the link axis is greater than a resilience of the first elastic body in the second radial direction relative to the link axis, the method comprising:
providing and positioning:
the first inner armature and the first outer armature, and
the second inner armature and the second outer armature;
molding:
the first elastic body between the first inner armature and first outer armature, so as to obtain the first sleeve, and
the second elastic body between the second inner armature and the second outer armature, so as to obtain the second sleeve; and
assembling the first sleeve and the second sleeve.
