Abstract
The invention discloses a wobble wheel rotary magneto-rheological damper. The damper consists of a wobble wheel, an outer barrel and a magnetic field generator; magneto-rheological liquid is filled between the wobble wheel and the outer barrel; and both the wobble wheel and the outer barrel are provided with a protruding damping bar. When the wobble wheel and the outer barrel produce relative rotation, the damping bars on the wobble wheel and the outer barrel extrude the magneto-rheological liquid from one side of each damping bar to the other side of each damping bar through the end face of each damping bar so as to generate a damping force, and the damping force adjusts the magnetic field strength of the magneto-rheological liquid to change the viscosity of the magneto-rheological liquid so as to change the rotary damping force of the rotary magneto-rheological damper.
Description
Technical field
The present invention relates to a kind of MR damper, be specifically related to a kind of rotary magneto-rheological damper.
Background technique
Common gyrodamping device is to adopt viscous grease that the principle of the motion generation damping force of moving element is made, the size of this class rotation damper moment of torsion is determined by the viscous damping oil viscosity, therefore, this class gyrodamping device moment of torsion in use is difficult to adjust.And of the present invention be rotary magneto-rheological damper, its torque can be adjusted by the intensity that changes magnetic field in good time, the present invention is simple in structure, and is easy to use, practical.
Summary of the invention
The objective of the invention is to propose a kind of Wobble wheel rotary magneto-rheological damper, this rotary magneto-rheological damper is to have used magnetic flow liquid under the different magnetic field strength condition, and the performance with different viscosities produces damping force;
Technological scheme of the present invention is as follows:
The present invention proposes a kind of Wobble wheel rotary magneto-rheological damper, this damper is to be made of escapement, urceolus and magnetic field generator, described escapement is installed in the urceolus, the wheel shaft at escapement two ends by urceolus two ends and stretch out in outside the urceolus, urceolus two ends and escapement wheel shaft adopt the sealing configuration sealing.The space that holds magnetic flow liquid is arranged between urceolus and the escapement, be full of magnetic flow liquid.
At least one amortisseur bar that protrudes is respectively arranged on the inner peripheral surface of escapement outer peripheral surface and urceolus, and along the circumferential direction stagger mutually in the amortisseur bar position on the inner peripheral surface of escapement outer peripheral surface and urceolus, have between the amortisseur bar on the described escapement and the inner peripheral surface of urceolus to stay and hold the gap that magnetic flow liquid passes through, also leave the gap that the appearance magnetic flow liquid passes through between the corresponding outer peripheral surface of the amortisseur bar on the urceolus inner peripheral surface and escapement.Magnetic field generator also is installed on the exterior edge face of urceolus.
In addition, at least one amortisseur bar that protrudes also can respectively be arranged on the end face of the end face of escapement and urceolus, and these two amortisseur bars place on escapement and the urceolus opposing end faces, and it staggers the amortisseur bar position on the end face of escapement and the end face of urceolus along in-plane, have between the end face of amortisseur bar and the urceolus opposing end faces on the described escapement to stay and hold the gap that magnetic flow liquid passes through, between the corresponding end face of the amortisseur bar on the urceolus end face and escapement the gap of staying the appearance magnetic flow liquid to pass through is arranged also.Magnetic field generator also is installed on the exterior edge face of urceolus.
When escapement and urceolus relatively rotate, magnetic flow liquid between escapement and urceolus amortisseur bar is under the extruding of amortisseur bar between escapement and urceolus, gap on escapement, the urceolus between amortisseur bar and escapement, the urceolus flows to opposite side from a side of the amortisseur bar end face by amortisseur bar.When on the end face of escapement and urceolus the amortisseur bar of a protrusion being arranged all, the flow pattern of magnetic flow liquid is identical with it therebetween, repeats no more herein.Utilize magnetic field generator to adjust the viscosity that changes magnetic flow liquid by the magnetic intensity of magnetic flow liquid, thereby make the damping force of rotary magneto-rheological damper controlled.
Rotary magneto-rheological damper of the present invention can also change the inherent damping parameter of this damper by structure, shape, size and the length that changes amortisseur bar on escapement, the urceolus.
Compare with existing viscous grease gyrodamping device, of the present invention is rotary magneto-rheological damper, and its torque can be adjusted by the intensity that changes magnetic field in good time, therefore uses convenient.
