The present summary refers to the invention patent for a crosshead assembly, which belongs to the field of the machines elements, particularly auto parts, which received improvement to present a simpler structure than that of the similar usual crossheads, comprised of genuine crosshead; clamps, which are assembled in the edges of the cardam axles and that receive the respective crosshead's arms; lubricant; and seals; such crosshead comprises a system that includes interfaces between the arms and the clamps without bearings (fixed); and the operation of the lubricant distribution carried out by such interfaces without bearings, which lubricates them when oscillations between the arms and the respective clamps happen; such interface between an arm and the respective clamp without bearings (fixed) is essentially comprised of: clamp with an internal surface provided with ribs interspersed by depressions; and by the crosshead's arm provided with a cylindrical smooth surface or vice-versa; such ribs touch the smooth surface in tangent points (interface) and the depressions house portions of lubricant, which touch sectors of the surface limited between the tangent points.
