THREE-POINT SUSPENSION ARM Russian patent published in 2024 - IPC B60G7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a suspension arm. The three-point suspension arm has two arms and a central hinge. The lever arms form an acute angle and are connected to a central hinge. The hinge has a hinged ball, a cylindrical tenon, and an anti-fall guard to prevent the hinge from complete separation. The tenon is located essentially perpendicular to the plane passing through both the arms of the lever. The ball is pierced with a spike. The guard acts as a stop and extends in a radial direction oriented perpendicular to the axial direction. The fuse is also pierced by a tenon and is protected by a ring-shaped locking element from axial extension of the tenon. The ring-shaped locking element, when viewed in the axial direction, is located on the side of the fuse facing away from the hinge ball and engages with the circumferential groove of the tenon. The annular locking element is enclosed with a radial contact by a guard in such a way that the annular locking element is prevented from slipping out of the circumferential groove of the tenon.

EFFECT: locking element is prevented from slipping out of the circumferential groove of the tenon.
