The invention provides a new style or design for a steel wheel in passenger vehicle with improvement in performance and aesthetics. In the new design steel wheel, a vent-hole may get folded and welded to an outboard bead seat of the steel wheel rim. The vent-hole folding itself may get turned as a flange portion for the steel wheel. This may significantly increases the vent-hole area, which may improve better air flow and cooling of the brake drum. The passenger vehicle steel wheel design can enable the ability to spot welding throughout the circumference of the rim-disc contact surface, for better contact and higher load/moment transfer. Further the passenger vehicle steel wheel may utilize an existing rim without any special machining or modification. Furthermore, the bigger wheel disc surface available provides room for more styling and aesthetic improvements.
The present invention provides a differential gutter wheel where in rim and disc are welded in the new construction. A differential gutter wheel comprises a flat base rim back section without gutter profile, an extended disk contains the gutter wall, a joint zone weld connecting extended disk edge surface and flat base rim back section and thus forms the required gutter profile. Thereby, the differential gutter wheel is shaped in a desired way, so as to increase the performance of the wheel. Further, the differential gutter wheel profile enables to higher inside clearance for brake component to be placed. In addition, the differential gutter wheel affords elimination of gutter forming operations during manufacturing and reduces the input raw material.
