The utility model provides a magnetism gear differential gearing and control mechanism, it needs among the mechanical transmission to keep apart the vibration, solve movive seal, drive interruption, variable speed and coupling transmission to be applicable to, transmits the forward moment of torsion all the time when guaranteeing to have continuous rotational speed poor between main, driven component, realizes infinitely variable speed, guarantees steadily to transmit the forward moment of torsion during specially adapted car variable speed.
Description
Technical field
The application belongs to mechanical transmission fields, particularly a kind of magnetic gear differential drive and control mechanism.
Background technique
Current transmission device has a variety of, can slippage transmission have fluid torque converter, it mainly relies on the conversion of the kinetic energy of working solution to realize differential transferring power, although transferring power is steady, its main problem is that oil consumption is high, and transmission efficiency is low.Permanent-magnet eddy current driving mechanism, is mainly used in the occasions such as chemical machinery, solves sealing and isolating technique, but volume is comparatively large, needs special sink.Permanent magnetism clutch actuation efficiency is high, but also cannot change its velocity ratio at present.
Model utility content
The application's object is to provide a kind of New Magnetic Field Controlled gear differential drive and control mechanism for above-mentioned deficiency, be applicable in mechanical transmission, to need separating vibration, solve motive sealing, interrupt transmission, speed change and coupled drive, ensure to transmit positive torque all the time when having continuous speed discrepancy (being slippage) between driving and driven element, realize electrodeless variable-speed, when being specially adapted to automobile variable speed, ensure smooth transfer positive torque.
Described magnetic gear differential drive and control mechanism, be made up of active member, full magnetic drive element, cylindrical magnet, link and bearing with magnetic tooth; Described active member is symmetrically connected with cylindrical connecting member up and down respectively, cylindrical connecting member connects a cylindrical magnet, forms an integrated member; Described integrated member is also connected with a cylindrical magnet moving up and down, forms a sliding pair, and the N pole of described cylindrical magnet moving up and down is respectively facing to the magnetic tooth N pole of drive element; Described magnetic tooth and drive element as a whole, be connected by bearing between active member with drive element.
When active member starts to rotate, the cylindrical magnet be connected on active member is rotated thereupon, the N pole of cylindrical magnet faces the N pole of magnetic tooth surface on drive element, because like pole repels mutually, the cylindrical magnet of rotating produces thrust F to magnetic tooth, the circumferential component of thrust F produces the moment of forward to drive element, drive element rotates thereupon.Active member drives drive element to produce different rotating speed, so can differential drive.Because the specific position of cylindrical magnet, magnetic tooth distributes, so can the positive torque of stable output constantly, drive drive element to rotate, thus realize stable drive.In order to reduce the energy loss in power transmission process, improving transmission efficiency, increasing working life of active member, take and connect with cylindrical connecting member the object that two cylindrical magnet and the effect of magnetic tooth reach buffering.When spacing between the N pole and the N pole of magnetic tooth of the direct acting cylindrical magnet of magnetic tooth is less, magnetic tooth has a larger opposition to cylindrical magnet, and like pole mutually repels and also produces active force between two cylindrical magnet, therefore constantly ringing, reach buffering, improve transmission efficiency, steadily moment of torsion, extend the effect in active member life-span.
Magnetic gear differential drive and the control mechanism of the application possess following advantage: (1) opposed poles may contact greatly hardly close to rear effect, therefore without the need to lubrication, clean, without friction energy loss, noiseless, without greasy dirt, dustproof and waterproof; (2) cylindrical magnet can be slided on magnetic tooth, and during startup, cylindrical magnet is necessarily in magnetic tooth lower position, and between each magnet, gap is comparatively large, and active force is more weak, and starting torque is lower; (3) when moment of torsion arrives to a certain degree, mechanism starts slippage occurs, and prevents high pulling torque from impacting driving mechanism thereafter, has overload protective function, easy to maintenance; (4) structure is simple, volume is little, be easy to processing; (5) use the repulsion of magnet, be different from and use the gravitation of magnet not worry magnet adhesion, can air gap between the reduction magnet of maximum possible, reach high pulling torque transmission; (6) magnet is permanent magnet, and permanent-magnet material conductivity is low, and the electric convolution of generation is little, and then the electric convolution loss produced is little, and transmission efficiency is high.
