Latest Patents

Mario holds a patent for a sleeve bearing designed specifically for internal combustion engine connecting rods. This invention features a bearing halfshell with an inner surface that maintains a substantially constant radius of curvature from a central plane of symmetry. The design includes two portions of the inner surface located on either side of the central plane, which are defined by surfaces with extra relief. This innovative structure allows for a gradual decrease in bearing thickness away from the central plane, forming two chambers that ensure a stable oil film between the bearing halfshell and the corresponding shaft. The elliptic contour of the eccentric surface contributes to improved performance and reduced operating temperatures.
