Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in accompanying drawing 1; The utility model comprises connecting rod 2, guider 23, piston, clutch release slave cylinder 22, base 14, gas receiver 4, seal and field coil 19, and described piston is to be made up of iron core 18, field coil 19, guide ring 17 and left magnetic isolating pad circle 20, right magnetic isolating pad circle 10; Described clutch release slave cylinder 22 is outside equipped with the gas receiver 4 of compensation link 2 volumes, and is fixed together with guider 23 and base 14 and gas receiver 4; The inflation post 9 of inflation in the oriented gas receiver 4 of these gas receiver 4 peripheral hardwares, 4 of this guider 23 and gas receivers accompany an oil sealing 5 24.
Described connecting rod 2 is placed in the clutch release slave cylinder 22, is fixed with a left cushion pad 7 on the connecting rod 2, a stop collar 8 is arranged and is fixed on the connecting rod 2 in that this left side cushion pad 7 is other; 4 of the left end of this connecting rod 2 and gas receivers are with a dust cover 3, and this dust cover 3 is fixed on the gas receiver 4.
Described seal is made up of left seal 5 and right seal 11, and gas receiver 4 is divided into three parts, promptly left liquid storage cylinder 25, air cavity 29 and right liquid storage cylinder 26; These left side seal 5 inherences are provided with oil sealing 4 21 near clutch release slave cylinder 22 ends, are being provided with oil sealing 1 near gas receiver 4 ends; These right side seal 11 inherences are provided with oil sealing 3 15 near clutch release slave cylinder 22 ends, are being provided with oil sealing 2 12 near gas receiver 4 ends.
Described piston is divided into left active chamber 28 and right active chamber 27 two-part with clutch release slave cylinder 22, and has clutch release slave cylinder aperture 31 at clutch release slave cylinder 22 near guider 23 ends.So that connecting rod 2 is to left movement time stream magnetic flow liquid, or the magnetic flow liquids in the left active chamber 28 are compensated when moving right.
Described base 14 is except that steady job cylinder 22; Which is provided with base aperture 30; And be fixed with a right cushion pad 13 being positioned at right active chamber 27 ends, so that connecting rod 2 compensates the magnetic flow liquid in the right active chamber 27 when left movement, or throttling magnetic flow liquid when moving right.
Described iron core 18, field coil 19, guide ring 17 and left magnetic isolating pad circle 20, right magnetic isolating pad circle 10 are fixed on connecting rod 2 right-hand members through nut 16; And having threading hole at the center of connecting rod 2, the coiling of field coil 19 is connected with wire harness 1 with threading hole on the connecting rod 2 through the wire casing on the iron core 18.
The working principle of the utility model is: at first in air cavity 29, charge into required pressure gas through inflation post 9, when connecting rod 2 drive pistons moved right with speed υ, right active chamber 27 was compressed, and the magnetic flow liquid in the chamber divides both direction to flow:
Part magnetic flow liquid is through the guide ring through hole 32 on the guide ring 17; Get into left active chamber 28 through damp channel, through damp channel the time, because field coil 19 energisings have produced magnetic field; And at iron core 18, damp channel 33 and 22 formation of clutch release slave cylinder magnetic loop (shown in accompanying drawing 2); The rectangular broken line block diagram is the magnetic loop distribution situation in this accompanying drawing 2, and V1 is the speed of magnetic flow liquid through damp channel, and υ is a link motion speed; Damping increased after magnetic-particle was magnetized in the magnetic flow liquid; Thereby change the damping characteristic of vibration damper; Its prominent features is that the change of damping constant can be controlled through the intensity of regulating electric current formation magnetic field, regulates electric current continuously and can realize continuously changing of resistance of shock absorber coefficient;
