ABSTRACT:
A process and apparatus for suspension of a vehicle wheel, particularly for motorcycles, mopeds and bicycles, the springs of which comprise an adjusting device. The process comprises the step of using a spring or springs having a neutralizable end part adapted to adjust the elastic deflection of the spring under the action of a load either progressively or by predetermined portions. Also, the apparatus comprises, in combination with a helical suspension spring, a hollow semi-collar, forming a nut, provided with peripheral knurl for permitting the manual handling thereof. The nut has two internal threads having the same pitch, over slightly more than a half-turn, for reacting, on the one hand, with the thread of a central non-deformable socket, and on the other hand, with the helical outside of the spring, for permitting locking of these three elements between themselves to achieve a predetermined height as a function of the variation of the supported load.
