PRODUCTION METHOD OF LIGHT ALLOY HYBRID WHEEL COMPRISING FRONT FLANGE AND RIM Russian patent published in 2019 - IPC B60B3/04 B60B21/02 B23K20/12 

FIELD: machine building.

SUBSTANCE: invention relates to the automotive industry. Method includes following separate working steps: manufacturing of flange (2) with internal profile (2a) with possibility of formation of tire bead seat; making rim, on one side, with outer profile (1a) with possibility of formation of tire bead seat and, on the other hand, with circular side surface (1b) for assembly with part (2b) of flange (2); assembling flange (2) with rim (1) at seat (2a) of mounting said flange (2) and circular side surface (1b) of rim (1); rim (1) is made according to the following consecutive operations: operation (P1) of production of circular side surface (1b) without welding; then expansion operation (P2) of said annular end surface (1b) to dimensions of final rim in one step; then, operation (P3) of cold or hot floss spinning of annular end surface (1b) so that to obtain rim (1) in its final shape and profile containing collar, only on the side which will not be welded to flange (2).

EFFECT: technical result is simplification of hybrid wheel manufacturing.
