Abstract
An axial air-gap permanent magnet automobile clutch with a magnetic concentrating block is formed by a fixed plate, a driving shaft, a driving plate, a driven shaft, a driven plate, the magnetic concentrating block, a magnetic yoke plate and magnetic poles; the fixed plate is in a circular ring shape and magnetic guiding teeth are arranged on the inner edge of the fixed plate; the driving plate is in a circular ring shape and a circle of magnetic shielding teeth which are uniformly distributed are arranged on the right end surface of the driving plate; the magnetic yoke plate is in a circular ring shape, a circle of teeth which are uniformly distributed are arranged on the outer edge of the magnetic yoke plate, one of the magnetic poles is fixed on every tooth; the driven plate is in a circular ring shape, a circle of driven plate magnetic guiding blocks which have the same number with the magnetic poles are arranged on the driven plate, and the driven plate magnetic guiding blocks are corresponding to the magnetic guiding teeth of the fixed plate and the magnetic poles to form air gaps. According to the axial air-gap permanent magnet automobile clutch with the magnetic concentrating block, the magnetic concentrating block is utilized, so that magnetic lines of force can be concentrated, the flux leakage is reduced, and accordingly the large moment of force can be transmitted by a small quantity of magnets.
Description
Technical field
The utility model relates to the clutch in a kind of car transmissions.
Background technique
Clutch is all housed between car 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 designed magnetic gear; The general radial clearance formula that adopts, the axial space in this kind of clutch only has 1/3rd can be used for installing magnet, and therefore, transmission capacity is restricted.
Model utility content
The purpose of this utility model is to provide a kind of axial air-gap permanent-magnet clutch for automobile with poly-magnetic patch; This clutch magnetic pole is placed in the end face of yoke dish tooth; By magnetic force transferring power, and with respect to magnetic shielding Chi position, change the magnetic force size between driven disc and driving disc by changing magnetic pole and yoke, realize clutch.Because magnetic pole, driving disc and the driven disc air gap between leading is very little, and can form a plurality of air gaps; And utilize poly-magnetic patch that the magnetic line of force is concentrated, reduce leakage field; Thereby can transmit large moment.
Structure of the present utility model is comprised of driving shaft, driving disc, driven shaft, driven disc, magnetic pole, poly-magnetic patch, encapsulation, yoke dish, fixed tray, magnetic shielding tooth, release bearing, shift fork, push rod, spring, flywheel, clutch housing.Wherein fixed tray is ring, is screwed on flywheel; Fixed tray inner edge is shaped with magnetic teeth.Driving disc is ring, by connecting plate and fixed tray, is fixed together; Right side is shaped with the equally distributed magnetic shielding tooth of a circle, for when magnetic pole and yoke dish retreat in magnetic shielding teeth groove, make the magnetic line of force form magnetic loop by magnetic shielding tooth, magnetic pole and yoke, and not by driven disc magnetic inductive block and fixed tray magnetic teeth, realize clutch separation.Yoke dish is ring, and yoke dish outer rim is shaped with the equally distributed tooth of a circle, fixes a magnetic pole on each tooth.Be encapsulated as ring, use non-magnet material manufacture, on it, outer rim is shaped with the equally distributed tooth of a circle; On each tooth, be shaped with magnetic pole and poly-magnetic patch and be combined the groove that shape and size are identical, place a magnetic pole and a poly-magnetic patch in encapsulation in the groove of each tooth, encapsulation is fixed on yoke dish.Poly-magnetic patch is made trapezoidal or convex shape cross section, and large facing to a lateral area of magnetic pole, opposite side area is little; For poly-magnetic and protection magnetic pole.Spring is that butterfly Huo Banxing， one end is fixed on yoke dish, and middle by movable being arranged on driving disc of rivet, the other end coordinates with release bearing; Spring force makes yoke dish in right position.Adjust bolt through yoke dish and driving disc Shang hole; Be used for limiting yoke Pan position and for yoke dish moves axially guiding, guarantee that yoke dish and driven disc have suitable gap.Driven disc is disc, uses non-magnet material manufacture, by spline, is loaded on driven shaft; On it, be shaped with a circle and be uniformly distributed the driven disc magnetic inductive block equating with pole number.Driven disc magnetic inductive block is corresponding with fixed tray magnetic teeth and magnetic pole, and forms air gap.Release bearing, for promoting spring to the right, makes yoke dish, magnetic pole in left position.
Working principle: during internal combustion engine, flywheel drives fixed tray, yoke dish, magnetic pole and driving disc to rotate; When not stepping on clutch, spring force makes yoke dish in right position, between yoke dish, magnetic pole, driven disc magnetic inductive block and fixed tray magnetic teeth, forms closed magnetic circuit.Magnetic force between magnetic pole, poly-magnetic patch, fixed tray, driving disc and driven disc is large, and the power of flywheel passes on driven disc by magnetic force, is equivalent to clutch and " closes ".When stepping on clutch, release bearing promotes spring the inner and take fixing rivet as fulcrum rotates, and makes yoke dish in left position, and magnetic pole retreats in magnetic shielding teeth groove, the magnetic line of force forms magnetic loop by magnetic shielding tooth, magnetic pole, poly-magnetic patch and yoke dish, and not by driven disc magnetic inductive block and fixed tray magnetic teeth; Magnetic pole and driving disc are led, the magnetic force between fixed tray and driven disc magnetic inductive block is very little, and power can not pass on driven disc, be equivalent to clutch " from ".
Owing to utilizing poly-magnetic patch that the magnetic line of force is concentrated, reduced leakage field; Thereby can transmit large moment with a small amount of magnet.
