<p>The integral frame intends to improve the steerability of "motorcycle" vehicles, reducing some of the defects of conventional ones. The more important ones are: 1) flexibility, under load, of fork and frame; 2) variations of wheelbase and forepart when travelling. Essentially, the integral frame achieves greater overall rigidity, constant distribution of the weights and steering geometry and reduction of the non-suspended masses. Integral means: monolithic structure, without oscillating hinged parts. In short, it envisages a central nucleus anchored to the engine, also having the function of tank and two stiff mono-arms which support the wheels laterally. These exploit a vertical stroke as they are rendered integral, by uprights, with special linear guides, keyed vertically to the ends of the arms. A special mechanism transfers their movement to the dampers, in the central part, for damping the stresses. The front wheel is steered by means of an arm articulated to the handlebar by means of a cardan joint moving on guides. <IMAGE></p> |
