US 2020/0055332 A1 · A NOVEL SADDLE LOCK RING FOR REAR DUAL WHEELS OF HEAVY TRANSPORT VEHICLE

Abstract

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.
