<p>The invention relates to a device comprising a central rotary cylinder (1) on which both groups of ball bearings (2, 2') are fixed, each one being fixed, via respective coupling joints (4, 4'), to corresponding elements (3, 3') that can be independently fixed to each of the bodies that rotatably interconnect in an articulated manner, allowing, based on the rotary cylinder (1) and the groups of ball bearings (2, 2'), the rotation and articulated interconnection of the two bodies, and the support of the stresses to which the different components are subjected. In addition to the central rotary cylinder, the two sets of ball bearings are joined by a second joining element which assists with the transmission of stresses between the two.</p> |
