In order to realize the utility model better; Said spring vibration damper mainly is made up of guide cylinder A, piston rod A and helical spring; The end of guide cylinder A is fixed on the pedestal, and the end of piston rod A is fixed on another pedestal, and the other end end of piston rod A is fixed with piston A; And it is inner that this end end is movably placed in guide cylinder A, and said spiral spring cover is installed in the outside of guide cylinder A and piston rod A.
Further, the corresponding spring seat that is provided with toroidal on said two pedestals, said helical spring is fixedly connected between the corresponding spring seat.
Further; Said electromagnetism damping device comprises guide cylinder B, piston rod B, top electromagnet and bottom electromagnet; The end of guide cylinder B is fixed on the pedestal, and the end of piston rod B is fixed on another pedestal, and the other end end of piston rod B is fixed with piston B; And it is inner that this end end is movably placed in guide cylinder B; The inner upper end of said guide cylinder B is fixed with the top electromagnet, and the piston B upper end of said piston rod B is fixed with the bottom electromagnet, and the bottom electromagnet places guide cylinder B inner fully.
As preferably, all have some threaded mounting holes on said two pedestals.
The utility model is compared than existing technology, has the following advantages and beneficial effect:
The utility model has combined spring and two kinds of damping modes of electromagnet to carry out damping, and damping effect is remarkable more, stable.The user can control two blocks of electromagnet and attract each other or repel, and the magnetic flux of two blocks of electromagnet also is to regulate, thereby can regulate and control two active forces between the electromagnet, to realize the purpose of compensator or trimmer pressure and damping.
During use; An elastic force detection device can be set on spring vibration damper; The elastic force detection device can detect the size of spring force in time, calculates machinery, vehicle vibration data through computer program, and computer sends to two blocks of electromagnet according to these data and discharges and recharges signal; Accomplish the adjusting of mutual magnetic force size of two blocks of electromagnet of intelligent control and direction, thereby accurately realize the damping purpose.
Adopt this vibration damper, not only improved damping effect greatly, and operation is very easy, improved the manufacturing efficiency of factory and the comfort level of vehicle ride.
