Electromagnetic attracting and repelling homopolar spacer ring row clutch

Abstract

The invention provides an electromagnet attraction and rejection homopolar spaced and annular emission clutch. The clutch comprises a driving shaft, a driving wheel and a driven wheel, wherein the driving shaft is sleeved with the driving wheel and the driven wheel. The clutch is characterized in that driving shaft spline teeth of the driving shaft are sleeved with driving wheel inner spline teeth, the outer ring of the driving wheel is a driving wheel outer wheel, and a plurality of electromagnet coils are symmetrically arranged on the outer side of the driving wheel outer wheel and can slip left and right on the outer side of the driving wheel outer wheel in the axial direction of the driving shaft; a plurality of driving wheel left magnetic blocks are symmetrically and annularly arranged on the left side of the driving wheel, driving wheel left magnet interblock magnet blocks are arranged in regions between every two driving wheel left magnetic blocks, and a circle of driving wheel outer wheel left teeth are symmetrically arranged on the left end face of the driving wheel outer wheel; the driven wheel is connected with the driving shaft through a driven wheel inner bearing; a circle of driven wheel right teeth are arranged in the region, corresponding to the driving wheel outer wheel left teeth, of the right side face of the driven wheel; the right side of the driven wheel is provided with a plurality of driven wheel right magnetic blocks; the driven wheel right magnetic blocks are correspondingly matched with the driving wheel left magnetic blocks.

Description

technical field [0001] The invention relates to an electromagnetic absorption and repelling homopolar interval annular clutch, which is suitable for various mechanisms that require clutch speed change and clutch speed regulation, such as clutch speed changers for various vehicles, gearboxes for lathes, etc., and belongs to the technical field of clutch and gear transmission. Background technique [0002] Today's automobile clutches include friction clutches, fluid couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission efficiency of these soft contacts is relatively high. Low; the reason why the modern developed automobile industry still uses the soft contact clutch method with low power transmission efficiency is because the meshed gears are difficult to separate when the gear meshing transmission rotates at high speed, and no hard ...

[0002] Today's automobile clutches include friction clutches, fluid couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission efficiency of these soft contacts is relatively high. Low; the reason why the modern developed automobile industry still uses the soft contact clutch method with low power transmission efficiency is because the meshed gears are difficult to separate when the gear meshing transmission rotates at high speed, and no hard transmission that is easy to mesh has not been found yet. The gear separation and gear meshing transmission method with higher transmission efficiency is a difficult problem in improving the transmission efficiency of automobiles; Wei Boqing's multiple invention patents "201410151795.6 Threaded sleeve clutch", "201410162087.2 Spring pressure friction gear meshing clutch", " 201410167388.4 Steel Disc Type Buffer Friction Gear Engagement Clutch", "201410169746.5 Compression Spring Type Buffer Friction Gear Engagement Clutch", "201410173268.5 Double Claw Disc Buffer Friction Thread Socket Clutch" can achieve high-efficiency transmission of gear clutch engagement, but the structure is complex, The volume is large, and the most important thing is that the present invention can utilize the relative spacing of the same-polar permanent magnets, so that the same-polar permanent magnets that are relatively spaced cannot be attracted to each other under the same speed rotation condition, so that The meshing of the side gears is guaranteed to be smooth, stable, and without toothing; the present invention provides a high-efficiency gear clutch meshing transmission structure through electromagnetic control and dislocation attraction of the same pole permanent magnet blocks at annular intervals
