ABSTRACT:
A wrist-pin, in which the inner tubular area is traversed by intersecting plates that traverse at the rotating axis and extending along at least a portion of the length, and thereby, said inner tubular area is divided into longitudinal sections. Ideally, the connecting-rod is positioned and affixed to the wrist-pin so that the first of such plates form traversed alignment with length of the connecting-rod, for directly transmitting forces from the piston, through said first plate, to the connecting-rod, whereas such forces are no longer effectively exerted upon the upper circular asymmetry of the wrist-pin, to prevent flexing of the wrist-pin. When stroke cycle progression positions the piston to be perpendicular to the connecting-rod, the second plate functions as a supplemental reinforcement member for the equalized force distribution about said upper circular asymmetry of the wrist-pin, thus to also prevent flexing, thereof, and providing for the acquired rigidity of the wrist-pin to he composed of non-traditional high-strength polymer composites or thin-walled metal.
