Abstract
According to the present invention an expandable joint is made without removable bearing caps by preassembling eccentric bushings onto the hinge pin. The expandable joint has a hinge type construction, but with the journals for each side of the hinge being spaced apart so that the distance between the two sides of the hinge changes with rotation of the hinge pin. The expandable joint of the present invention is assembled by sliding the hinge pin into the hinged joint with the eccentric bushings attached. Once the hinge pin is in place, the eccentric bushings are locked in place with fasteners so that they do not rotate. After the eccentric bushings are locked in place, the hinge pin can be turned to expand the joint. The expandable joint is intended for use in variable compression ratio engines, where expansion of the joint changes the compression ratio of the engine.
