Method to produce base concave rims, concave base hoop and vehicle wheel with such hoop for commercial vehicles

摘要

This invention refers to a method for producing a concave base ring and a concave base ring for commercial vehicle vehicle wheels. The rim has a plurality of zones, which form an internal rim flange (11) and an external rim flange (20),An inward steep tapered Talon seat (12) and an external narrow Talon seat (19) and a concave rim base with a concave centre base (13),An internal concave base flank (14) and an external concave base flank (15) between steep tapered Talon seats, in which one of the areas is provided as a disk link region to a wheel disc (50),And the concave base rim has at least one partial area with a reduced wall thickness compared to other areas. According to the invention, at least one of the steep tapered Talon seats (12, 19),Preferably both steep narrow Talon seats (12, 19),Has /have a section with a reduction in wall thickness above 20% in relation to wall thickness in the area supplied as the disk link region (a),Where the wall thickness reduction is produced during one of the profiling steps.
