Background technique
Mechanical shock is a common phenomena in engineering machinery and the vehicle, and in most of the cases, mechanical shock is harmful to.Present known vibration damper has following two kinds:
First kind is spring type shock absorber, though this vibration damper also can play the effect of damping, in engineering machinery or field of automobile, the elastic force of the spring that vibration damper adopted is generally all bigger.Under less shock conditions, damping spring just can not produce resiliently deformable, and this vibration damper also just plays damping hardly, and plays the effect of rigid support fully, and the people who at this moment is sitting in the automobile will feel under the weather, sometimes even feel that health feels bad.Like this, the vibration damper that can only prepare different damping performances for the engineering machinery or the automobile of various different models and different purposes could be realized best damping effect better.And in a single day the spring in the vibration damper is processed, and its stiffness characteristics has just been confirmed, can not change, the online in real time control that can not shake.
Second kind is hydra-shock absorber, and it is to move up and down in oil cylinder through a wear-resisting withstand voltage rubber piston, promotes in-oil cylinder hydraulic oil through a stress reduction device, makes hydraulic oil under certain pressure, play damping effect.But present hydraulic damper mainly contains two defectives: one, the single-stage damping effect is undesirable; When using it on automobile shock purposes, when when vehicle driving, running into the height point of a protrusion, vibration damper will receive outside impact force to be expressed to a minimum point to it; And vibration damper is when being in low spot; It self rebounding force will strengthen, and can throw a higher high point to vehicle, and the weight of itself can produce vehicle vibrations again.Two, existing vibration damper is when utilizing gravity to reduce pressure hydraulic oil through relieving apparatus; The few of hydraulic oil in high-voltage oil cylinder the inside; When vehicle runs into rough road surface once more,, so just let vehicle lose shock-absorbing protecting because hydraulic oil can not in time cover.
The model utility content
The purpose of the utility model is to overcome the many disadvantages of existing vibration damper; Provide a kind of spring and two kinds of modes that combine of electromagnet of adopting to carry out damping; The both abundant flexible damping performance that has used spring; Utilized the principle of magnet homopolar-repulsion again, made damping effect more stable, and its shock absorbing characteristics can be realized intelligent the adjusting.
The purpose of the utility model realizes through following technical proposals:
A kind of vibration damper comprises two pedestals, is provided with spring vibration damper and electromagnetism damping device between said two pedestals.
In order to play damping effect better, and make that this vibration damper structure is more stable, said spring vibration damper quantity is four.
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.
