In order to solve the problem, the solution that the present invention proposes is: the multistage diffraction of single pole active single control mutative damp MR damper, and it comprises cylinder block, cylinder body left end cap, cylinder body right end cap, diffraction piston modules, gradual change working clearance, power supply, magnetic flow liquid; Described cylinder body left end cap, described cylinder body right end cap are installed in the left and right two ends of described cylinder block respectively; Described diffraction piston modules is installed in the inside of described cylinder block.
The coil protect layer that cylinder block of the present invention comprises cylinder body body, is wound in the hot-wire coil of described cylinder body body exterior, is installed in described hot-wire coil outside; Described cylinder body right end cap comprises right end cap body, the bearing hole be opened on described right end cap body, the linear bearing be installed in described bearing hole, be installed in seal arrangement inside described bearing hole; Described diffraction piston modules comprises piston rod, the piston only be installed on described piston rod, the gradual change working clearance be opened on described piston only.
Piston only of the present invention is cylindrical body, and its diameter equals the internal diameter of described cylinder body body; One end that described gradual change working clearance internal diameter is larger is working clearance large mouth, and become the left room of liquid with stream and communicate, the other end is working clearance osculum, and right ventricle communicates with Liu Bian liquid; The described gradual change working clearance is the circular channel of the internal diameter gradual change of serpentine bend; The described cylinder body body that inside is full of described magnetic flow liquid by described piston only is divided into two-part: stream becomes the left room of liquid and Liu Bian liquid right ventricle; Described power supply is installed on described right end cap body, and is connected with described hot-wire coil with wire.
Compared with prior art, the invention has the advantages that: the multistage diffraction of single pole of the present invention active single control mutative damp MR damper is provided with the gradual change working clearance of hot-wire coil and serpentine bend, stream becomes liquid and flows between right ventricle at the stream change left room of liquid, Liu Bian liquid by the gradual change working clearance; In hot-wire coil, the change of electric current makes to flow the corresponding change of viscosity generation becoming liquid.It can thus be appreciated that the present invention is simple and reasonable, adopt and become the adjustment that working clearance and magnetic intensity realize magnetorheological fluid damp power, the regulation range of damping force obtains remarkable improvement.
