  • Patent number: 11745597
    Abstract: Inertial suspension magnetic stabilizer that complements the suspension of vehicles and mobiles of different nature, opposing and compensating inertially to sudden impulses; mountable to wheel cups or to the wheel axis support, preferably constructed in a body preferably forming a hollow cylinder containing gaseous or liquid fluids, composed of a hermetic tubular body provided at its ends with fixed magnets and in its central area of a magnetically neutral sliding piston, supported by its magnet ends with equal polarity, facing, to that of the magnets fixed at the ends of the tubular body; sliding piston that in turn divides the tubular body into two hermetic chambers linked together, by a tube provided with a fluid regulating valve.

  • Patent number: 6050558
    Abstract: A pneumatic cylinder, inside which a piston is displaced and which defines two chambers. The chambers are communicated through a first conduit passing through the piston and a second conduit at the ends of which there are variable flow valves. The first conduit has an adjustable valve. The load at any air chamber results in a working load which causes contact of the wheel with the ground for a longer period of time. An expansion spring is located at the lower air chamber. The piston is engaged with means for sensing its displacement. The invention could be applied to any kind of vehicle.
