Abstract
A belt pulley type axial magnetic gap permanent magnetic clutch is provided. The clutch is structurally composed of a belt pulley, a driving disc, a driven shaft, a driven disc, a magnetic yoke disc, magnetic poles and a bearing, wherein the driving disc and the driven disc are made of non-magnetic conductive materials, and magnetic conductive blocks having the same amount as the magnetic poles are uniformly distributed on the driving disc and the driven disc in a loop; the driving disc is disposed in the belt pulley through a transmission tooth, and the driven disc is disposed on the driven shaft through a spline; the magnetic poles are fixed on the magnetic yoke disc; and multiple air gaps are formed between the driven disc, the driving disc and the magnetic poles. The working principle is that when the clutch is not stamped down, spring force enables the magnetic yoke disc to be in a right position, and the magnetic yoke disc, the magnetic poles, the driving disc magnetic conductive blocks, the driven disc magnetic conductive blocks and end caps form a closed magnetic circuit, and when the magnetic force between the magnetic poles, the driving disc and the driven disc is large, the power of the belt pulley is transmitted to the driven disc by the power, which equals to a connection function of the clutch. When the magnetic yoke disc is in a left position, the magnetic poles are retreated into magnetic shielding gullets, the majority of magnetic lines of force and the magnetic yoke disc form a magnetic circuit through magnetic shielding teeth and the magnetic poles, and the magnetic force between the driving disc and the driven disk disappears and the power of a flywheel cannot be transmitted to the driven disc.
Description
Technical field
The utility model relates to the clutch in a kind of vehicle drive system.
Background technology
Clutch all is housed between vehicle internal combustion engine and the 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 designed magnetic gear; The general radial clearance formula that adopts, the axial space in this kind clutch have only 1/3rd can be used for magnet is installed, and therefore, transmission capacity is restricted.
The utility model content
The purpose of this utility model provides the wheeled axial magnetic of a kind of belt crack Permanent Magnet Clutch, and this clutch is built in the drive system big belt pulley; By the magnetic force transferring power of axial air-gap, and change magnetic force size between clutch plate and the driving disc spacing pressing by changing magnetic pole and yoke with respect to the position of magnetic screen tooth, realize clutch.Because the air gap between magnetic pole, driving disc spacing pressing and the clutch plate is very little, and a plurality of clutch plates and driving disc spacing pressing can be set, and forms a plurality of air gaps; The axial space in the clutch can be taken full advantage of, thereby the big square of power can be transmitted.
Structure of the present utility model is made up of belt pulley, driving disc spacing pressing, driven shaft, clutch plate, yoke dish, magnetic pole, release bearing, separator levers, spring and bearing.Its middle belt pulley is drum shape, and inwall is shaped on driving cog; The left end inner face circumferentially is shaped on the equally distributed magnetic screen tooth of a circle, be used for when magnetic pole and yoke dish retreat in the magnetic screen teeth groove, make most magnetic lines of force form magnetic loop by magnetic screen tooth, magnetic pole and yoke dish, and not by clutch plate and driving disc spacing pressing, realize clutch separation; Belt pulley is installed on the driven shaft by bearing.Driving disc spacing pressing is annular, uses the non-magnet material manufacturing, is shaped on the driving disc spacing pressing magnetic inductive block that a circle evenly distributes and equates with the magnetic pole number on it, is used for magnetic conduction.The yoke dish is annular, is shaped on the equally distributed tooth of a circle on the yoke dish, fixes a magnetic pole on each tooth.Pull bar one end is fixed on the yoke dish, and the other end cooperates with the separator levers outer end.Clutch plate is disc, uses the non-magnet material manufacturing, is loaded on the driven shaft by spline; Be shaped on the clutch plate magnetic inductive block that a circle evenly distributes and equates with the magnetic pole number on it.The clutch plate magnetic inductive block is with initiatively magnetic inductive block and magnetic pole are corresponding, and the formation air gap.Spring one end withstands on the belt pulley, and the other end withstands on the yoke dish; Spring force makes yoke dish, magnetic pole be in right position.Release bearing is used for promoting separator levers to the right, makes yoke dish, magnetic pole be in position, a left side by pull bar.End cap is disc, is screwed on belt pulley, is shaped on the magnetic teeth that a circle evenly distributes and equates with the magnetic pole number on it.
Operation principle: belt pulley drives driving disc spacing pressing, yoke dish and magnetic pole and rotates; When not stepping on clutch, spring force makes the yoke dish be in right position, forms closed magnetic circuit between yoke dish, magnetic pole, clutch plate magnetic inductive block and active magnetic inductive block and the end cap magnetic teeth; Magnetic force between magnetic pole, driving disc spacing pressing and the clutch plate is big, and the power of belt pulley passes on the clutch plate by magnetic force, is equivalent to clutch and " closes ".When stepping on clutch, release bearing makes yoke dish, magnetic pole be in position, a left side by separator levers, pull bar, and magnetic pole retreats in the magnetic screen teeth groove, and most magnetic lines of force form magnetic loop by magnetic screen tooth, magnetic pole and yoke dish, and not by clutch plate and driving disc spacing pressing; Magnetic force between magnetic pole and the master and slave Moving plate is disappeared, and the power of flywheel can not pass on the clutch plate, be equivalent to clutch " from ".
Owing to form a plurality of small air gaps between the wheeled axial magnetic of belt crack Permanent Magnet Clutch clutch plate, magnetic pole and the driving disc spacing pressing, can improve the transmission capacity of clutch greatly.
