Abstract: The present invention discloses an electromagnetic shock absorber which may be employed to prevent the bottoming of springs in autos during shock conditions, or to replace, in its entirety, a shock absorber.The present shock absorber includes two electro-magnets, the first having a fixed north-to-south field and the second having a field whose polarity is reversible dependant upon the direction of the shock which is to be absorbed or dampened. Where the undesirable shock involves a movement of the car axle toward the auto frame, the polarity of the magnet having a reversible field causes a repulsion between the two electro-magnets. Where the undesirable motion of the car axle is away from the auto frame, the field of the reversible magnet creates an attraction between the two electro-magnets.Hence, any undesirable motion of the auto axle relative to the auto frame is counteracted by virtue of the present system.
