“VZN” is an automotive smart shock absorber concept, this acronym being abbreviation for VARIABLE ZETA NECESSARY for well behavior in all road and load conditions, where ZETA represents the relative damping, which is stepwise changed automatically, according to the piston position.The self adjustable shock absorber VZN, realized without electronics or mechanisms, grant with European Patent EP 1190184 B1, and Romanian Patent 118546 B1, has an energy dissipation system made of an inner cylinder having sideways damping valves, placed optimally between to the ends.Comparative with standard shock absorbers having constant rebound/compression damping coefficients, the VZN concept, give a wide range of damping coefficients along the stroke. So for identical damping valves/metering holes the damping coefficients decreases with the square number of active valves/metering holes, meaning values between (0.1 to 100)× (Standard damping coefficients), and more.The theoretical and by simulation results denotes the VZN concept confers, the next advantages relative to the standard ones:
