Abstract
A kind of MR damper of embedded with spring automatic protection is the utility model is related to, belongs to mechanical oscillation engineering field.Magnetic flow liquid is full of in the MR damper cylinder barrel, and it is sealed against by end cap, the piston for winding magnet exciting coil is put into cylinder barrel, the left and right end face of piston is connected to the piston guide rod of equivalent diameter, piston guide rod passes through the end cap with through hole, it is connected between piston left side and left end cap and between piston right side and right end cap by spring, the spring of left and right two can play certain damping effect in MR damper normal work, simultaneously when control loop breaks down, under the damping effect of spring, play certain self-protection function.
Description
Technical field
It the utility model is related to the magnetic current variable resistance of a kind of MR damper device, specifically embedded with spring automatic protection
Buddhist nun's device device.
Background technology
At present, known MR damper is by magnetic flow liquid, cylinder barrel and several parts such as the piston with magnet exciting coil
Form, by adding electric current to magnet exciting coil, produce electromagnetic field, using magnetic rheology effect, change the viscosity of magnetic flow liquid, so as to change
Become the size of power output, reach good damping effect.But because electrical equipment control has certain unstability, once
Circuit or control element break down, and will lose the damping effect of damper, easily cause some dangerous accidents.
The content of the invention
In order to overcome potential safety hazard existing for MR damper, the utility model provides a kind of MR damper, from
And certain self-protection function can be played when control loop breaks down.
Technical scheme is used by the utility model solves its technical problem：The piston for winding magnet exciting coil is put first
Enter in cylinder barrel, the left and right end face of piston is connected to the piston guide rod of equivalent diameter, and piston guide rod passes through the end with through hole
Lid, end cap are closely connected with cylinder barrel, magnetic flow liquid are sealed in cylinder barrel, and between piston left side and left end cap and piston is right
It is connected between end face and right end cap by spring, the spring of left and right two can play necessarily in MR damper normal work
Damping effect, while when control loop breaks down, under the damping effect of spring, play certain self-shield work(
Energy.
The beneficial effects of the utility model are, it is possible to reduce the energy consumption of MR damper, increase maximum output damping force,
Certain defencive function can also be played, reduces the incidence of peril.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structure principle chart of the present utility model.
The piston guide rod of 1. lead, 2. end cap, 3. cylinder barrel, 4. piston, 5. damp channel, 6. coil, 7. spring 8. in figure
9. magnetic flow liquid.
Embodiment
Magnet exciting coil 6 is orderly first is wrapped on piston 4, and the lead 1 of magnet exciting coil 6 is drawn by the endoporus of piston guide rod 8
Go out, then the piston 4 for winding magnet exciting coil 6 is put into cylinder barrel, the left and right end face of piston 4 is connected to the work of equivalent diameter
Guide rod 8 is filled in, piston guide rod 8 passes through the end cap 2 with through hole, and end cap 2 is closely connected with cylinder barrel 3, and magnetic flow liquid 9 is sealed in into cylinder
In cylinder, it is connected between piston left side and left end cap and by spring 7 between piston right side and right end cap, the bullet of left and right two
Spring can play certain damping effect in MR damper normal work, while when control loop breaks down
Wait, under the damping effect of spring, play certain self-protection function.
