Title:
A DUAL WHEEL ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2002057095
Kind Code:
A9
Abstract:
A dual wheel assembly is formed by an inner wheel (10) and an outer wheel (30) coaxially mounted on a common hub (11). The inner wheel (10) has an inner tyre (13) mounted on an inner wheel rim (12). The outer wheel (30) has an outer tyre (13A) mounted on an outer wheel rim (32). The tyres (13, 13A) are of the same size, but the diameter of the outer wheel rim (32) is smaller then the inner wheel rim (12), to permit the inner tyre (13) to pass over the outer wheel rim (32), thereby enabling the inner tyre (13) to be removed without first removing the outer wheel rim (32). Removable bead seats (37, 40) are provided between the oute wheel rim (32) and its tyre (13A). These bead seats (37, 40) are thicker than the corresponding bead seat(s) on the inner wheel (10) to compensate for the reduced diameter of the outer wheel rim (32).
