Description
Technical field
The utility model relates to the clutch in a kind of vehicle drive system.
Background technology
All clutch is housed between various vehicle internal combustion engine and speed changer, generally adopts friction-type; But this clutch wear and tear in use than very fast, the life-span is shorter.For this reason, people have devised magnetic gear; The mode of the mobile magnetic conductive disk of general employing realizes clutch, and because magnetic gap is comparatively large, magnet consumption is large, makes the manufacturing cost of magnetic gear higher than friction-type; And dismounting adjustment inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of built-in belt pulley Permanent Magnet Clutch, and this clutch is built in drive system big belt pulley; By magnetic force transferring power, and by changing the position of magnetic conductive disk, changing the magnetic force size between clutch plate and driving disc spacing pressing, realizing clutch.Due to nothing friction between master and slave Moving plate, work more reliable; Adopt ferrite lattice, cost is lower.
Structure of the present utility model is made up of belt pulley, driving disc spacing pressing, initiatively magnetic conduction ring gear, driven shaft, clutch plate, magnetic conductive disk, yoke dish, magnet, magnetism-isolating loop, release bearing, pull bar, connecting plate, spring and bearing.Its middle belt pulley is drum-shaped, is arranged on driven shaft by bearing; Magnetism-isolating loop is annular, uses non-magnet material manufacture, and is shaped with some guiding teeth; Be fixed on belt pulley inwall; Magnet is annular or watt shape, axial charging; Be bonded in position bottom belt pulley, for generation of magnetic field.Initiatively magnetic conduction ring gear is annular, is fixed on magnetism-isolating loop; End face is shaped with a circle and is uniformly distributed the tooth identical with protecgulum magnetic teeth number; Driving disc spacing pressing is disc, uses non-magnet material manufacture, it is shaped with a circle and is uniformly distributed the driving disc spacing pressing magnetic inductive block equal with the protecgulum magnetic conduction number of teeth; Driving disc spacing pressing is fixed on magnetism-isolating loop.Yoke dish is disc, and left side and magnet are bonded together, and has certain intervals, form magnet isolation tank between yoke dish and active magnetic conduction ring gear.Clutch plate is disc, uses non-magnet material manufacture, is loaded on driven shaft by spline; It is shaped with a circle and is uniformly distributed the clutch plate magnetic inductive block equal with the protecgulum magnetic conduction number of teeth; Clutch plate magnetic inductive block is corresponding with the tooth of protecgulum magnetic teeth and active magnetic conduction ring gear, and forms air gap.Magnetic conductive disk is disc, and external diameter is with initiatively magnetic conduction ring gear internal diameter is identical; And can slide in active magnetic conduction ring gear.Pull bar one end is fixed on magnetic conductive disk, and the other end is through the hole on belt pulley and yoke dish; For driving the position of magnetic conductive disk and restriction magnetic conductive disk.Spring housing is on pull bar, and spring force makes magnetic conductive disk be in left position.Release bearing and connecting plate are used for rightmost derivation disk.
Operation principle: during internal combustion engine, belt pulley drives driving disc spacing pressing, initiatively magnetic conduction ring gear and protecgulum to rotate.When not stepping on clutch, spring force makes magnetic conductive disk be in left position; Magnetic conductive disk, in yoke with initiatively between magnetic conduction ring gear, strides across magnet isolation tank; Closed magnetic circuit is formed between magnet, yoke dish, magnetic conductive disk, active magnetic conduction ring gear, clutch plate magnetic inductive block, protecgulum magnetic teeth and belt pulley.Magnetic force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, driving disc spacing pressing magnetic inductive block, protecgulum magnetic teeth air gap is large, and the power of belt pulley passes on clutch plate by magnetic force, is equivalent to clutch " conjunction ".When stepping on clutch, release bearing, connecting plate and pull bar promote magnetic conductive disk to the right, and magnetic conductive disk is pushed away magnet isolation tank, all enter in active magnetic conduction ring gear; The magnetic line of force that magnet produces does not enter initiatively magnetic conduction ring gear by magnet isolation tank, the magnetic line of force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, driving disc spacing pressing magnetic inductive block, protecgulum magnetic teeth air gap is little, the power of belt pulley can not pass on clutch plate by magnetic force, is equivalent to clutch "Off".
Magnet due to built-in belt pulley Permanent Magnet Clutch is watt shape of annular or negligible amounts, install, fix and magnetize conveniently, and initiatively form four small air gaps between magnetic conduction ring gear, driving disc spacing pressing magnetic inductive block, clutch plate magnetic inductive block, protecgulum magnetic teeth, the consumption of magnet can be greatly reduced.
