ABSTRACT:
A double universal joint comprises two individual universal joints and a member positioned axially between the individual universal joints is connected to the first members of each joint. A centering plate extends perpendicularly to the axis of rotation of the connecting member and is guided for sliding movement in its own plane. The centering plate is disposed within a casing having guide surfaces for guiding the spherical outer surfaces of the second joint members of the individual universal joints. The centers of curvature of the outer spherical surfaces are offset equal distances from the centers of the respective individual universal joints when the joint is in its straight or unbent position.
