RADIAL JOINT AND PROCEDURE FOR FABRICATION OF SIMILAR RADIAL JOINT FOR VEHICLE Russian patent published in 2011 - IPC F16C11/06 B21D53/00 

FIELD: machine building.

SUBSTANCE: here is disclosed radial joint for vehicle with solid metal case (1) open on one side. Ball journal (3) is inserted through orifice (2) of the case into internal space (4) of case (1). Also, ball head (5) of ball journal (3) is installed in bearing zone of internal space (4) where it turns and rotates, while section (6) of ball journal (3) connected with ball head (5) projects from case (1) through orifice (2) of case (1). Case (1) in the zone of its orifice (2) has section (7) cut from external side and deformed by cold shaping. Also, here is claimed the procedure for fabrication of the said joint. The procedure consists in the following stages: fabrication of a case blank; cutting on external side of the section (7) near orifice (2) of case (1); insertion of head (5) of journal (3) into internal space (4) of case (1); cold shaping end section of case (1) on the side of the orifice till obtaining metal overlap (13) between head (5) and case (1).

EFFECT: radial joint of simple design; reliable connection with geometrical locking between contact elements; adequate resistance to extraction of fabricated joint.
