Abstract
In the embodiments of the invention described in the specification, a piston and a connecting rod of an internal combustion engine have opposed approximately semi-cylindrical bearing regions partially enclosing a pin, leaving free gaps between the bearing regions to permit swivel motions of the piston and connecting rod about the axis of the pin. Two symmetrical rings which surround the pin axis retain the bearing regions against the pin. The provision of such opposed bearing regions reduces the oscillating mass of the link joint.
Claims4
A traction- and pressure-transmitting link joint between two structural components executing joint movements, comprising a cylindrical pin, a first structural component having a substantially semi-cylindrical bearing surface engaging the surface of the pin and lying on one side of the pin axis, a second structural component having a substantially semi-cylindrical bearing surface engaging the surface of the pin on the opposite side of the pin axis from the first structural component bearing surface engagement, the entire bearing surface regions of the first and second structural components lying on opposite sides of the pin axis and the total portion of the circumference of the pin engaged by the bearing surfaces being less than 360.degree., and at least one ring surrounding the pin and the bearing surface portions of the first and second components and retaining the first and second component bearing surfaces in engagement with the surface of the pin wherein the ring is mounted to permit lateral displacement of the first and second components in the direction of the axis of the pin.
