Abstract
Suspension for a wheeled vehicle provided with at least one wheel and a frame, having at least one elastic element functionally combinable between the wheel and frame is disclosed. The suspension has at least one hydro-pneumatic spring functionally combined in series with the elastic element so that the equivalent spring modulus (Keq) of the elastic element and hydro-pneumatic spring is variable as a function of the distance between the frame and wheel. The hydro-pneumatic spring is shaped and sized to behave also as an energy dissipator in series to the elastic element.

Suspension for a wheeled vehicle provided with a wheel and a frame, comprising an elastic element functionally combinable between said wheel and said frame, said suspension comprising a hydro-pneumatic spring functionally combined in series with said elastic element so that the equivalent spring modulus (Keq) of said elastic element and said hydro-pneumatic spring is variable as a function of the distance between said frame and said wheel, said hydro-pneumatic spring being shaped and sized to behave also as an energy dissipator in series to said elastic element and to dissipate kinetic energy of between 20 and 40% of the total kinetic energy collected in each cycle by the hydro-pneumatic spring,
- wherein said suspension lacks a fluidic damper arranged in parallel with said elastic element between said frame and said wheel and said hydro-pneumatic spring has a preload force greater than that of said elastic element.
Method for the functioning of a suspension for a wheeled vehicle provided with a wheel and a frame, comprising an elastic element functionally combinable between said wheel and said frame, said suspension comprising a hydro-pneumatic spring functionally combined in series with said elastic element so that the equivalent spring modulus (Keq) of said elastic element and said hydro-pneumatic spring is variable as a function of the distance between said frame and said wheel, said hydro-pneumatic spring being shaped and sized to behave also as an energy dissipator in series to said elastic element and to dissipate kinetic energy of between 20 and 40% of the total kinetic energy collected in each cycle by the hydro-pneumatic spring, wherein said suspension lacks a fluidic damper arranged in parallel with said elastic element between said frame and said wheel, said method comprising the step of setting a preload force for said hydro-pneumatic spring greater than that of said elastic element.
