[0002] The magneto-rheological damper is an intelligent damping device. The existing piston-type magneto-rheological damper mostly adopts the structure of a piston and a working cylinder. This type of piston-type magnetorheological damper is obtained by changing the excitation coil on the piston. In the current, the electromagnetic field strength in the annular gap between the outer diameter of the piston and the inner diameter of the working cylinder (ie: working gap) changes to adjust the viscosity of the magnetorheological fluid to adjust the damping force. Because of this magnetic The rheological damper has only one working gap, so the adjustment range of its damping force is small

technical field [0001] The invention relates to a magneto-rheological damper, in particular to a magneto-rheological damper with a single rod and multiple damping tubes. Background technique [0002] The magneto-rheological damper is an intelligent damping device. The existing piston-type magneto-rheological damper mostly adopts the structure of a piston and a working cylinder. This type of piston-type magnetorheological damper is obtained by changing the excitation coil on the piston. In the current, the electromagnetic field strength in the annular gap between the outer diameter of the piston and the inner diameter of the working cylinder (ie: working gap) changes to adjust the viscosity of the magnetorheological fluid to adjust the damping force. Because of this magnetic The rheological damper has only one working gap, so the adjustment range of its damping force is small. Contents of the invention [0003] In order to overcome the disadvantages of the existing piston ...
