Electromagnetic shock absorber

An electromagnetic shock absorbing system, intended to maintain the sprung and unsprung elements of a mechanical system at a fixed distance from each other, comprising:

• a. a linear velocity transducer medially coupled between said sprung and unsprung elements, said transducer serving to convey A current flow proportional in magnitude to the velocity of relative motion between said sprung and unsprung elements and, further, having a direction of flow which is a function of the direction of relative movement between said sprung and unsprung elements;
• b. a first electromagnet having a polarity which, regardless of the direction of its input current from said transducer, is arbitrarily maintained in a single direction, said first electromagnet being longitudinally disposed between said sprung and unsprung elements;
• and
• c. a second electromagnet, electrically coupled to the output of said transducer, having a polarity which is directly proportional to the direction of relative movement between said sprung and unsprung elements, said second electromagnet longitudinally disposed between said elements and, further, disposed upon the same longitudinal axis as said first electromagnet,
• whereby said second electromagnet will, under conditions in which said sprung and unsprung elements are moving apart, experience a direction of current flow about it which will produce an electromagnetic field which will attract the adjacent poles of said first and second electromagnets to each other, and, conversely, under conditions in which said sprung and unsprung elements are moving toward each other will produce an electromagnetic field in which adjacent poles of said first and second electromagnets will repulse each other, thus creating a desired damping and shock absorbing effect within any suspension system into which the present system may be incorporated.
