Description
Technical field
It a kind of is encouraged the utility model is related to a kind of magnetic rheological brake more particularly to using permanent magnet and magnet exciting coil
Haptic device magnetic rheological brake.
Background technology
In haptic device application, quick, stabilization plays an important role for the promotion of device performance with instantaneous response,
Common liquid braking device is generally used in conventional apparatus, since the working media of filling is hydraulic oil, viscosity is small and can not
Become, therefore output torque is smaller and damped coefficient is non-adjustable, is not well positioned to meet requirement of the haptic device for response characteristic.
The appearance of magnetorheological fluid is to solve above-mentioned problem to bring new thinking, and moment can under magnetic fields for magnetorheological fluid
Inverse rheological behavior can change the shear yield strength of magnetorheological fluid by controlling magnetic field intensity, realize magnetorheological braking
The step-less adjustment of device torque.Magnetic rheological brake can be divided into linear magnetic rheological brake and rotary magnetic according to motion mode
Rheology brake.Compared to revolving type magnetic rheologic brake, although linear magnetic rheological brake is using relatively extensively having
Obvious disadvantage such as needs larger installation space；Big impulse stroke cannot be accommodated because brake bar have deformation it is curved
Bent danger；The exposure on bar surface makes bar be become larger by the probability that exterior object injures, while can be by close in brake cylinder body
Seal the friction of element.
Conventional rotary magnetic rheological brake generates magnetic field only with magnet exciting coil, when brake a period of time out of service
Afterwards, the magnetorheological fluid magnetic-particle in brake will produce sedimentation or aggregation and form lump and cake shape object, when brake again
When operation, the lump and cake shape object can block damp channel to make brake lose damping capacity.In addition, if system power supply
It breaks down when to make the exciting current of magnetic rheological brake be zero, brake output torque is small and can not adjust.

When magnets magnetic fields direction is opposite with energization magnet exciting coil magnetic direction, by controlling magnet exciting coil electrical current size, Ke Yishi
Existing shaft is freely rotated；When magnet exciting coil is not powered on, still there is permanent magnet to generate magnetic field, improves the automatic anti-event of brake
Hinder performance；In addition permanent magnet can be such that the magnetorheological fluid moment is in magnetic field, generate magnetic rheology effect, avoid magnetorheological fluid from occurring heavy
Drop or aggregation form lump and cake shape object.Magnet exciting coil and permanent magnet are used cooperatively by the utility model, and using magnetic guiding loop and
The combination of magnetism-isolating loop forms a kind of snakelike magnetic flux path, effectively increases torque and the working performance of magnetic rheological brake.
