The passive and active suspension with optimized energy use

摘要

Abstract invention patent: "the passive and active suspension with optimized energy use." A hydraulic actuator includes a buffer and a control system that is separate from the buffer and generates damping loads to the hydraulic actuator.The control system generates the load damping using a pair of variable valves, a pair of check valves, an accumulator, a pump / motor and a controller of the flow. The forces are generated in all four quadrants of the compression / expansion and active / passive.A device which recovers the energy generated by the hydraulic actuator may be incorporated into the hydraulic actuator to generate energy in the form of electric power.
