HINGED JOINT Russian patent published in 2024 - IPC F16C11/00 

FIELD: machine building.

SUBSTANCE: hinged joint comprising a lever, a lug housing, an axis, compensating bushings, conical antifriction bushings, a mechanism for pressing the compensating bushings, differs by the fact that compensating bushings are made in the form of cylindrical bushings with inner conical surfaces making the shape of a bicone, cylindrical surfaces of the bushings are locked by pins relative to the lug housing, the axis has the shape of a bicone and is made with mating bushings with outer conical surfaces, wherein the maximum thickening lies in the middle of the axis in the axial direction, between the axis and the bushings there are antifriction bushings of the corresponding conical shape, having on the side of the base of the cone alternately inward and outward in the radial direction flat leaf springs, wherein axle and conical bushes have mating grooves to be locked according to the ratchet mechanism principle.

EFFECT: provision of guaranteed exclusion of negative effect of reverse effect at friction and increase of axle strength.
