SPHERICAL PIVOT JOINT Russian patent published in 2006 - IPC F16C11/06 

FIELD: mechanical engineering, in particular, spherical pivot joints for vehicle front suspension.

SUBSTANCE: spherical pivot joint has seamless forged casing formed as hemisphere made integral with connection flange, finger equipped with head and mounted inside casing hemisphere, and polymeric insert disposed therebetween. Lower part of finger head and lower part of casing hemisphere are provided with end surfaces defining lower cavity of pivot joint, said cavity being filled with lubricant. Annular protrusions are disposed on larger diameter of head finger, above and below it. Annular protrusions define annular cavities connected with each other into labyrinth and defining in conjunction with insert inner surface other cavities filled with lubricant. End surface of casing hemisphere has slot.

EFFECT: reduced friction coefficient of finger-insert pair and increased extent of fixing said insert within casing.
