Description
Technical field
The utility model relates to a kind of automobile suspension system vibration damper, especially relates to a kind of magnetic flow liquid vibration damper of half ACTIVE CONTROL.
Background technique
The damping of automotive suspension can be divided into active and passive shock mitigation system.Active suspension system has only in the world at present on the top automobile of minority and adopts because its complex structure, control require high, factor such as cost an arm and a leg.What extensively adopted at present the home and abroad is the passive energy dissipation system, adopts the external core structure, utilizes the fluid damping technology of its orifice restriction to consume the energy that produces in the vibration processes.External takes up room greatly, poor reliability, and its dynamic performance is not good enough.
The model utility content
Technical problem to be solved in the utility model provides a kind of compact structure, the suspension vibration can be controlled in real time and moment is reversible, helps improving a kind of new automobile magnetic flow liquid vibration damper of riding comfort and operational stability.
For solving the problems of the technologies described above, the utility model provides a kind of novel magnetic flow liquid vibration damper, mainly comprise suspension ring assembly, clutch release slave cylinder, piston rod, end cap, coil, seal ring and guide line, the suspension ring assembly links to each other with automobile axle, be provided with magnetic flow liquid in the cavity between piston rod and the clutch release slave cylinder, end cap links to each other by welding manner with clutch release slave cylinder, and seal ring is installed in the inboard and the outside of end cap radial direction, guide line links to each other with coil, and draws by the endoporus of piston and piston rod.
In the cavity between piston rod and the clutch release slave cylinder floating piston is set, floating piston is divided into two chambeies up and down with the cavity between piston rod and the clutch release slave cylinder, is filled with nitrogen in the cavity of resorption, is filled with magnetic flow liquid in the epicoele, and one-way valve is welded on the clutch release slave cylinder.
The magnetic flow liquid that the utility model adopts has adaptive damping, and rheological properties moment (about 10 milliseconds) changes and reversible, cheap, insensitive to polluting, characteristics such as control is stepless, accurate, rapid, reliable performance is stablized, power consumption is little.Not only be convenient to guiding but also make the magnetic flow liquid fluid be convenient to fine flowing, on piston rod, be provided with targeting part, one-way valve can solve the size of filling nitrogen pressure and be convenient to fill nitrogen, reduce noise, solve the real-time control of motor racing process vibration preferably, will become the substitute products of present widely used hydraulic damper soon in the future.
Description of drawings

Fig. 2 is the suspension ring component drawings.
Embodiment
With reference to Fig. 1, the utility model comprises suspension ring assembly 1, clutch release slave cylinder 5, piston rod 6, end cap 12, coil 15 and guide line 17; For the magnetic flow liquid that prevents inside, chamber, a floating piston left side oozes out by the piston rod center hole, be provided with sealing epoxy plastics 14, for not only being convenient to guiding but also realize small damping control, adopted special structure, be about to conventional piston rod construction and be divided into piston rod 6, piston 3 and bolt 4 three parts, they are by screw thread and being weldingly connected, upwards arrange 8 bigger holes in 6 weeks of piston rod, being convenient to magnetic flow liquid flows, be drilled with aperture in the center portion, be convenient to guide line 17 and draw, piston rod 6 external diameters closely contact with clutch release slave cylinder 5, are used for whole guiding; Bolt 4 is used for piston 3 and is closely linked with piston rod 6, its external diameter is slightly smaller than the internal diameter of clutch release slave cylinder 5, guarantee that magnetic flow liquid slowly flows out and enough big damping function arranged at both gap location, its axial aperture is used for guide line 17 safety to be derived, and the epoxy plastics of piston 3 and bolt 4 ends is used to prevent that magnetic flow liquid from oozing out along guide line.7 is that guide sleeve, 8-11 are that combined seal ring, 16 is seal ring.
For reducing the noise that the piston rod to-and-fro motion produces, floating piston 2 is set in the cavity between piston rod and the clutch release slave cylinder, floating piston is divided into two chambeies up and down with the cavity between piston rod and the clutch release slave cylinder, be filled with nitrogen in the cavity of resorption, be filled with magnetic flow liquid in the epicoele, one-way valve 13 is welded on the clutch release slave cylinder, is used to control the size of institute's inflated with nitrogen pressure.
Consider the integral damping balance of device, the piston rod working portion adopts symplex structure, does not produce the side direction unbalanced force with assurance device; For guaranteeing piston rod left side chamber magnetic flow liquid free-flow free lifting and accurately locating; Be provided with 8 holes at targeting part; Between piston 3 and the clutch release slave cylinder inner chamber 1 mm clearance is arranged, purpose is to play the effect of small damping.
Fig. 2 is the suspension ring assembly, and wherein 1-1 is interior ring, and 1-2 is an elastomer, and 1-3 is an outer shroud.
When automobile friction or less vibration travel, guide line 17 no applied voltages, when detection device detects the bigger vibration of automobile generation, control system applies the pilot certain voltage, the alive outside effect of coil 15 produces magnetic field down, at this moment make that the magnetic flow liquid that flows through between piston 3 and the clutch release slave cylinder becomes the class solid, damping increases, the relative clutch release slave cylinder movement velocity of piston rod reduces, reach the purpose that reduces to vibrate, after vibration was reduced to certain value, adding the voltage that control system is applied to coil was zero, and magnetic flow liquid returns to original fluid state again.So constantly, constantly adjust the viscosity of coil control voltage and magnetic flow liquid, reach the damping purpose according to online detection vibrational state.
