ABSTRACT:
A pivot pin construction for pivot joints, particularly universal joints wherein an inner and an outer member are provided in the construction. A spacing is provided between the inner and outer members and a resilient mass is secured in the spacing. The spacing between the inner and outer members is enlarged at the axial ends thereof so that when the pivot pin is displaced, the volume of the displaced resilient mass in one plane plus the volume of the displaced resilient mass in an adjacent plane is absorbed by the volume between the two surfaces in the respective plane.
