ROLLED CAGE, DEVICE FOR ROLLED CAGE PRODUCTION AND METHOD OF ROLLED CAGE MANUFACTURE Russian patent published in 2018 - IPC F16F15/08 B60G7/02 B60G9/04 F16F1/38 

FIELD: protective devices.

SUBSTANCE: group of inventions refers to a rolling cage that is part of the suspension mechanism. Rolled cage is a steel roll cage, where a polymer bushing is pressed and that is welded to the connecting element. Rolled cage comprises a main part in the form of a hollow cylinder and a gripping portion connecting the two end surfaces of the main body to each other by means of an insert. Rolled cage comprises a cut out part formed by cutting out a portion of the annular edge of the main body. In the cut out part, a convex conductor is inserted to position the main part during welding. Rolled cage comprises a hollow portion formed as a cavity from the inner side of the round surface on the wall surface around the cut part to create a gap between the pressed polymeric bushing and the edge section of the cut part on the inner side of the round surface.

EFFECT: achieved the prevention of damage of the polymer bushing surface when it is pressed, even if there is a configuration for positioning during welding.
