Abstract
The utility model discloses a centrifugal brake shoe extrusion magneto-rheological clutch. The clutch comprises a driving sleeve and a driven mechanism, wherein a baffle is fixedly arranged at one end of the driving sleeve; the driven mechanism is sleeved on the driving sleeve in a rolling mode; a closed cavity is defined by the driven mechanism, the driving sleeve and the baffle; magneto-rheological fluid is filled in the cavity; a coil is arranged on the driven mechanism; and at least two brake shoes which rotate with the driving sleeve to extrude the magneto-rheological fluid are uniformly distributed on the driving sleeve in the cavity. The clutch has the advantages that the coil is electrified, the magneto-rheological fluid is changed into a solid, the brake shoes extrude a shell through centrifugal force generated when the driving sleeve rotates, and high torque can be transmitted; and the clutch is small in size and has reliable performance, a compact structure and a good effect.
Description
Technical field
The utility model relates to centrifugal brake shoe extruding magnetic rheological clutch.
Background technique
Magnetic flow liquid is low with its response fast (Millisecond), energy consumption, be easy to advantage such as control, serviceability is good, operating temperature range is wide, long service life and be widely used in Aero-Space/machining/precision engineering/fields such as building/medical treatment.
Magnetic rheological clutch is through the control that adds magnetic intensity being realized clutch combines, separation function, even can realize the stepless variation control that moment of torsion transmits.It is easy to wear that it has overcome conventional clutch; Shortcomings such as noise is big; Simple in structure with it, do not have mechanical wearing and tearing, low noise, response rapidly (in 10 milliseconds), energy consumption not high, can realize stepless speed regulation and be more conducive to combine realize that advantage such as intellectuality control has caused the broad research of Chinese scholars and industrial quarters with computer technology, make remarkable progress in recent years.But the not enough problem of Shear Yield Stress of Magnetorheological Fluids is just perplexing magnetic flow liquid material and technological development from magnetic converting technique always during birthday; Magnetic rheological clutch according to existing Shear Yield Stress of Magnetorheological Fluids design; Less and bulky because of its transmitting torque, can't satisfy industrial requirement.
The model utility content
The purpose of the utility model is to provide centrifugal brake shoe extruding magnetic rheological clutch, can effectively solve existing clutch with magnetic rheologic liquid and can only adopt shear mode work, the low problem of transmission torque.
In order to solve the problems of the technologies described above; The utility model is realized through following technological scheme: centrifugal brake shoe extruding magnetic rheological clutch; Comprise initiatively sleeve, follower, an end of said active sleeve is fixed with baffle plate, and said follower rolls and is socketed on the active sleeve; Said follower is with initiatively sleeve, baffle plate surround sealed cavity; Charge into magnetic flow liquid in the said cavity, said follower is provided with coil, is evenly equipped with at least two on the active sleeve in the said cavity along with the active sleeve rotates and the brake shoe of extruding magnetic flow liquid.
Preferably; Have ladder hole on the said brake shoe; Have on the active sleeve in the said cavity with brake shoe with respect to tapped hole, brake shoe passes ladder hole through bolt and is fixedly connected with tapped hole, is provided with spring between the head of said bolt and the ladder of ladder hole; The restriction brake shoe can only move radially, so that make full use of centrifugal force magnetic flow liquid is pushed.
Preferably; Said follower comprises housing, follower, and said housing surrounds cavity with active sleeve, baffle plate, and said coil is arranged on the housing; Said housing is fixedly connected with the sidewall of follower, and said follower is set on the active sleeve through rolling bearing; Both guarantee to form good cavity, and can guarantee good output again.
Preferably, be provided with seal ring between said housing and the active sleeve; Prevent that magnetic flow liquid from flowing out cavity.
Compared with prior art, the utility model has the advantages that: coil electricity makes magnetic flow liquid become solid, and utilizing initiatively sleeve rotation is that the centrifugal force that produces makes generation extruding between brake shoe and the housing; Can transmit bigger torque, and volume is little, reliable performance; Compact structure, respond well.

Fig. 2 is an A-A sectional view among Fig. 1.
Embodiment
Consult Fig. 1, Fig. 2 embodiment for the centrifugal brake shoe 8 extruding magnetic rheological clutchs of the utility model, centrifugal brake shoe 8 extruding magnetic rheological clutchs comprise initiatively sleeve 2, follower; One end of said active sleeve 2 is fixed with baffle plate 3; Said follower rolls and is socketed on the active sleeve 2, and said follower surrounds sealed cavity with active sleeve 2, baffle plate 3, charges into magnetic flow liquid 5 in the said cavity; Said follower is provided with coil 6; Be evenly equipped with four on the active sleeve 2 in the said cavity and have ladder hole 9 on the said brake shoe 8 along with active sleeve 2 rotates and the brake shoes 8 of extruding magnetic flow liquid 5, have on the active sleeve 2 in the said cavity with brake shoe 8 with respect to tapped hole; Brake shoe 8 passes ladder hole 9 through bolt 10 and is fixedly connected with tapped hole; Be provided with spring 11 between the ladder of the head of said bolt 10 and ladder hole 9, said follower comprises housing 4, follower 7, and said housing 4 is with initiatively sleeve 2, baffle plate 3 surround cavity; Said coil 6 is arranged on the housing 4; Said housing 4 is fixedly connected with the sidewall of follower 7, and said follower 7 is set on the active sleeve 2 through rolling bearing, is provided with seal ring 1 between said housing 4 and the active sleeve 2.
During work, coil 6 energising produces magnetic fields, and magnetic flow liquid 5 becomes solid by liquid; When active sleeve 2 rotation certain speeds, it is big that centrifugal force becomes, brake shoe 8 because of centrifugal force to housing 4 extrusion type solid magnetic flow liquids 5; Thereby produce big warping force, spread out of through follower 7; When active sleeve 2 speed diminish, coil 6 outages simultaneously, then brake shoe 8 is resetted by spring 11, and clutch is not worked.
The above is merely the specific embodiment of the utility model; But the technical characteristics of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
