A vehicle wheel suspension system includes two relatively movable portions and a resilient blade that includes two means for mechanical connection to both relatively movable portions, respectively. The blade has a flexural resilience at least 100 times greater than the tensile resilience, and is resiliently deformable between: a resting state in which the blade has an inwardly curved profile, and a maximally extended state in which the blade has an elongate profile, the length of which corresponds to that of the neutral fiber of the blade, while passing through intermediate extension states in which the blade has profiles that are less and less inwardly curved. The suspension system is deformable between an initial state in which the relatively movable portions are in a close configuration, and a compressed state in which the relatively movable portions are in a separated configuration and bias the blade.

Cycle-type vehicle suspension provided with a resilient element for making it possible to obtain an optimal static compression curve, and optimized resilient element for such suspension
