Description
Technical field
The utility model relates to vibration damper field, is specially a kind of MR vibration damper of intelligent control.
Background technique
Magneto-rheological vibration damper utilizes inductive reaction, based on the input information from monitoring car body and wheel movement sensors, makes real-time response to road conditions and driving environment.Magnetic rheological liquid is the soft grain suspension of a kind of magnetic, be injected into the electromagnetic coil in damper piston when liquid after, the magnetic field of coil will change its rheological properties (or producing fluid resistance), thus there is no electromechanical control valve and under the simple situation of mechanical device, produce be swift in response, damping force that controllability is strong.Magneto-rheological vibration damper have the adjustable multiple of damping force high, be easy to realize that computer mutative damp controls in real time, compact structure and the feature such as outside input energy is little, be day by day subject to the great attention of engineering circles.
Existing MR vibration damper can not respond timely to the stressing conditions of self, but carry out Signal transmissions by outside sensor, this mode just causes there will be error in the process of Signal transmissions, cause judging inaccurate, therefore damping effect can be slightly delayed, for the Consumer pursuing high-speed response, traditional magnetorheological damping can not reach requirement.
Model utility content
The purpose of this utility model is the MR vibration damper providing a kind of intelligent control, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme: a kind of MR vibration damper of intelligent control, comprise magnetic rheological liquid cylinder, piston rod and magnetic induction coil, described magnetic rheological liquid cylinder is cylindrical structure, the described lower end of magnetic rheological liquid cylinder and the top of piston rod are all fixedly connected with connecting ring, through hole is all left in the inner side of described connecting ring, the upside of described magnetic rheological liquid cylinder is connected with cylinder cap by internal and external threads, described piston rod runs through with cylinder cap and is connected, the bottom of described piston rod is fixedly connected with piston head, the middle part of described piston head is provided with magnetic induction loop, the left and right sides of described piston head is provided with through hole, the middle part of described through hole is provided with magnetic hysteresis chamber, described magnetic hysteresis chamber is positioned at the outside of magnetic induction loop, the top of described piston head is provided with controller and pressure transducer, described controller is positioned at the left side of pressure transducer, described magnetic induction loop and pressure transducer are all electrically connected with controller.
Preferably, be fixedly connected with reinforcing ring in the middle part of the upper-end surface of described cylinder cap, described reinforcing ring is socketed in the outside of piston rod.
Preferably, the outside of described piston head is connected with leakage-proof ring.
Compared with prior art, the beneficial effects of the utility model are: this MR vibration damper structure is simple, by adding pressure transducer structure on piston head top, can detect the pressure of magnetic rheological liquid cylinder top inner chamber timely, and by signal transmission to controller, when the signal that pressure transducer is subject to is malleation, the downside inner chamber necessarily negative pressure of magnetic rheological liquid cylinder, so piston rod is now about to move downwards, be a vibrations crest, otherwise, when the signal that pressure transducer is subject to is negative pressure, the downside inner chamber necessarily malleation of magnetic rheological liquid cylinder, in both cases, controller all can connect magnetic induction loop timely, that it produces the magnetic field of correspondence direction, the magnetic field produced produces magnetic induction to the magnetic rheological liquid that magnetic rheological liquid cylinder interior is filled instantaneously, magnetic rheological liquid moment becomes the high fluid of viscosity factor from the fluid that viscosity factor is lower, and the internal condensate in magnetic hysteresis chamber, by the through hole viscous of piston head, thus reach the object of damping, by the direct mode arranging sensor at magnetic rheological liquid cylinder interior, the signal of vibration wave can be directly detected, therefore the magnetorheological damping device response than traditional is faster.
