摘要： This invention relates to a unitary steel wheel as well as the apparatus and method of producing a unitary steel wheel. The unitary wheel comprises wheel rim (2,2,4) and disc portions. In one embodiment, the unitary wheel of this invention further comprise a one-piece wheel of 5° and 15° drop center rims, providing a generally circular steel blank from a sheet stock of pre-determined substantially uniform thickness. The bank preferably has a center hole having a predetermined size. The blank is performed in a spinning machine to a predetermined profile and shape. The perform is further spun and flow formed in a spinning machine, the perform being positioned between an outer roll (F1) and inner mandrel (M1) and held against a clamping plate (C1). The inner mandrel (M1) comprises an outboard surface, which conforms to the predetermined inner diameter of the rim (2,3,4). The preform is further processed in the spinning machine to form a final shape and profile of the rim portion comprising a well (3) , inner (1) and outer (5) flange portions, and inner(2) and outer (4) bead-seat portions.

摘要： 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.

摘要： The present invention relates to a novel design for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The invention provides a safe design that comprises a two-piece segmented saddle lock ring retained in position by an endless ring. A self-locking taper provided on the inside of endless ring can be pressed against the taper provided on the two-piece segmented saddle lock ring. The endless ring retaining the two-piece segmented saddle lock rings due to wedge action of self-locking taper cannot move from its position until an external force is applied on the endless ring towards the direction of the tyre position. The endless ring acts as a hood over the two-piece segmented saddle lock rings and prevents any loose parts flying off the rim during the tyre burst. Further in this safe design both inboard and outboard rim tyre support components are identical as both rims are of same diameter.
