A lock-ring system may include one or more lock-ring sections configured to at least partially define an annular lock-ring and one or more coupler plates configured to couple a first ring section end of a first lock-ring section to either a second ring section end of the first lock-ring section or to a ring section end of a second lock-ring section. The one or more coupler plates may be configured to be received in ring recesses of the one or more lock-ring sections. The one or more coupler plates may be coupled to the one or more ring section ends by fasteners and may be configured to slide relative to the ring recesses when the fasteners are loosened, so that a lock-ring formed by the one or more lock-ring sections may be mounted on, or removed from, a wheel assembly. A handle may be used to assist with maintaining separation of the lock-ring sections during handling and to assist with handling the lock-ring during removal and installation of the lock-ring on a wheel assembly.

A dual wheel adapter assembly for mounting dual wheel rims to a wheel hub is provided. The dual wheel adapter assembly may include a hollow cylindrical adapter, including a central bore defined by an inner surface of the adapter, a first contact surface, and a second contact surface. The dual wheel adapter assembly may also include an inboard wheel rim configured to support a tire, an outboard wheel rim configured to support a tire, and a wedge clamp configured to be coupled to the hub. The first contact surface may abut the hub and the wedge clamp may apply a compressive force to the second contact surface to couple the adapter to the hub.

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.
