Abstract
The utility model relates to a novel small-air gap permanent magnet automobile clutch comprising a driving shaft, a driving disc, a driven shaft, a driven disc, a magnet yoke and magnetic poles, wherein the driving disc is fixed on a flywheel; driving teeth are arranged on the driving disc; the packaging is shaped like a circular ring and made from non-magnetic materials; the magnet yoke and a plurality of pairs of magnetic poles are embedded in the packaging; the driven disc is shaped like a circular ring; teeth with same number as the magnetic poles are arranged on the driven disc; and air gaps are formed among the driven disc teeth, the driving teeth and the magnetic poles. The working principle is described as follows: when an internal combustion engine works, the driving disc is driven by the driving shaft to rotate; when the clutch is not pressed down, the magnet yoke is forced by a spring to be at the left position, a closed magnetic circuit is formed among the magnet yoke, the magnetic poles, the driven disc teeth and the driving teeth, the magnetic force among the magnetic poles, the driven disc teeth and the driving teeth is large, power of the flywheel is transmitted to the driven disc by means of the magnetic force, so that the coupling of the clutch is realized; and when the clutch is pressed down, the packaging is at the right position, the closed magnetic circuit is formed among the magnetic poles and a magnetic ring, the magnetic force among the magnetic poles, the driven disc teeth and the driving teeth disappears and the power of the flywheel cannot be transmitted to the driven disc, so that the separation of the clutch is realized.
Description
Technical field
The utility model relates to the clutch in a kind of car transmissions.
Background technique
Clutch all is housed between car 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 mode of mobile magnetic guiding loop that adopts realizes clutch, and because magnetic gap is larger, the magnet consumption is many, makes the manufacture cost of magnetic gear be higher than friction type.
The model utility content
The purpose of this utility model provides a kind of novel small air gap permanent-magnet clutch for automobile; This clutch changes the magnetic force between driven disc and the driving disc by changing magnetic pole and yoke with respect to the position of driven disc.Because the air gap between magnetic pole and driven disc is very little, and the air gap number is many, thereby greatly reduce at the condition lower magnet consumption that transmits identical moment.
Structure of the present utility model is comprised of driving shaft, driven shaft, magnetic pole, yoke, encapsulation, driving disc, magnetic guiding loop, driving tooth retaining ring, driven disc, guiding tooth, release bearing, shift fork, pull bar, spring, spring bracket, flywheel, clutch housing.Wherein driving disc is by inside and outside two rings that annulus forms, and ring is as magnetic guiding loop in it; Be shaped with the guiding tooth in its outer shroud; The driving tooth retaining ring is ring, is fixed on the driving disc; Be shaped with a few driving tooths on it, driving disc is screwed on flywheel.Be encapsulated as ring, make with non-magnet material, embedded yoke and some to magnetic pole places in the driving disc; Driving several guiding grooves on its outer rim cooperates with guiding tooth on the driving disc; Encapsulation and driving disc are circumferentially linked together; And the relative driving disc of encapsulation is endwisely slipped.The left side of encapsulation is fixed with pull bar, and support is fixed on the driving disc, and screw rod passes the hole on the support, and an end is fixed on the pull bar, and the other end cover is useful on the spring that makes encapsulation be in left position.Shift fork and release bearing are bearing on the spline housing, are used for promoting encapsulation and move right.Driven disc also for how annular, is made with non-magnet material; The driven disc tooth that is shaped with on each ring, the interior toothrow is made gear ring (gear ring also can be contained in driving tooth retaining ring inner ring).Driven disc is loaded on the driven shaft by spline, and the driven disc tooth is corresponding with driving tooth and magnetic pole, and and driving tooth and magnetic pole between form a plurality of air gaps.Driven shaft on flywheel, which is provided with positioning retainer ring and sleeve by bearings, and accurately position is arranged when being used for making driven disc work.
Working principle: during internal combustion engine, driving shaft drives driving disc, magnetic guiding loop and yoke and rotates together; When not stepping on clutch, spring makes yoke be in left position; Form closed magnetic circuit between yoke, magnetic pole, driven disc tooth and the driving tooth.Magnetic force between magnetic pole, driven disc tooth and the driving tooth is large, and the power of flywheel passes on the driven disc by magnetic force, is equivalent to clutch and " closes ".When stepping on clutch, shift fork promotes release bearing moves right encapsulation by pushing-pulling-plate; Yoke, magnetic pole are in right position, and magnetic pole cooperates with magnetic guiding loop, form closed magnetic circuit; Magnetic force between magnetic pole and the master and slave Moving plate tooth is disappeared, and the power of flywheel can not pass on the driven disc; Be equivalent to clutch " from ".
Owing to form a plurality of small air gaps between the tooth on the novel small air gap permanent-magnet clutch for automobile driven disc and magnetic pole and the driving tooth, magnetic force is multiplied, can greatly reduce the consumption of magnet.
