Abstract:
An electromagnetic shock absorber comprising:an housing, said housing having a first end portion and a second end portion, said housing having a perimeter wall extending from said first end portion to said second end portion, said second end portion having a rod aperture extending therethrough; a first electromagnet assembly, said first electromagnet assembly being positioned within an interior of said housing defined by said first and second end portions and said perimeter wall of said housing, said first electromagnet assembly being positioned adjacent said first end portion of said housing; a second electromagnet assembly, said second electromagnet assembly being positioned within an interior of said housing defined by said first and second end portions and said perimeter wall of said housing, said second electromagnet assembly being positioned adjacent said second end portion of said housing; a rod assembly, said rod assembly having a rod member including an rod member first portion and a rod member second portion, said rod member first portion extending into said housing through said rod aperture; a moving electromagnet assembly, said moving electromagnet assembly being coupled to said rod member first portion, said moving electromagnet assembly being positioned within said housing; said moving electromagnet assembly having an upper plate, a lower plate, a shaft portion, a conductive member, and a pair of connecting leads; said upper plate and said lower plate being in a fixed substantially parallel spaced relationship with respect to each other, said shaft portion extending between said upper and lower plates for holding said upper and lower plates in said fixed relationship; said shaft portion having an interior cavity defined by a perimeter wall, said shaft member having a connecting lead aperture; each of said upper and lower plates and said shaft portion being coupled to said rod member such that sliding said rod member into and out of said interior of said housing through said rod aperture moves said moving electromagnet assembly between a lower plate of said first electromagnet assembly and an upper plate of said second electromagnet assembly.
