摘要：
The present invention relates to a structure with multiple independent wheels for cycles or engine-driven vehicles which run on an irregular bearing surface. The structure is comprised of two twin wheels (10, 11) which are interconnected by two toggle-levers (12). Each of the two wheels (10 and 11) is comprised of a central part (13) and a peripheral part (14). The central part is fixed and the peripheral part rotates and is concentric with the central part. Both parts (13 and 14) are coupled to each other by a crown-shaped roller bearing (15) which is comprised of an inner annular element (16) and a rotary outer annular element (17). The two levers (12) are connected to the suspension by arms (20). The device provides an optimum adherence to road surfaces.
