This invention relates to a suspension for vehicles, wherein the wheels are associated with the bodywork by means of a flexible assembly essentially constituted by two longitudinal blades and by two transverse blades connected to the bodywork by means of elastically deformable connecting elements, wherein:--the ends of the longitudinal blades and transverse blades are located in two planes spaced apart from each other, these two planes being parallel or not;--at the front of the chassis, the ends of the longitudinal blades are mounted so as to allow a momentary longitudinal displacement under the effect of a shock and to avoid any transverse or angular displacement;--at the rear of the chassis, the ends of the longitudinal blades are blocked in torsion in the hub-holder elements.
