BALL PIN OF BALL HINGE FOR TRANSPORT VEHICLE, AND METHOD FOR ITS MANUFACTURE Russian patent published in 2012 - IPC F16C11/06 B60G7/00 B62D7/16 

FIELD: machine building.

SUBSTANCE: ball pin includes ball pin body and auxiliary flange plate. Body of ball pin includes spherical head, neck made on spherical head, flange made on the neck, connecting part made on the flange and threaded part which is made on connecting part and is coaxial to it. Threaded part has outer diameter exceeding the diameter of connecting part. Plate is put on connecting part. In central section of the plate there formed is through connecting hole which has the diameter which is smaller than outer diameter of threaded part. Plate has surface area of support surface, which is larger than surface area of support surface of the flange. Manufacturing method of the above ball pin is also proposed. The method consists in the fact that ball pin body is formed; then, threaded part is introduced to plate hole and plate is pushed in the direction of flange until central section of lower end of the plate comes into contact with the flange. Then, the plate supported from the flange is pushed till it is converted to flat shape; at that, the hole is reduced.

EFFECT: creation of ball pin of ball hinge, which can be made by means of easy manufacturing process.
