Background technique
Energy crisis and environmental pollution problem have impact on the energy-consuming idea in the whole world.Some main industrially developed country have worked out strict automobile fuel ecomomy regulation, and alleviate automotive body weight and can reduce fuel consume, the more equipment of assembling, improve the performance of automobile, therefore, automobile manufacturers, in order to reduce oil consumption, is managing to improve fuel economy, while improving car air pertormance, put forth effort on the research of automotive light weight technology.
As effective energy saving means, automotive light weight technology technology is one of important subject becoming automobile industry development.Automotive light weight technology is the urgent needs that national energy-saving reduces discharging strategy, more becomes the current demand of car enterprise and whole industry raising core competence.And the loss of weight of each parts of automobile is inevitable requirements of automotive light weight technology, comprise the lightweight of magnetic clutch.
The weight of lightweight mainly by using new design or new material to alleviate magnetic clutch of magnetic clutch.Aluminum alloy, plastics (polymer matrix composites), magnesium alloy think ideal three class materials at present.For magnetic clutch, first material has magnetic conductivity, also need to possess the performances such as wear resistance, rigidity, intensity, hardness and high-low temperature resistant simultaneously, select new material to substitute steel to realize light-weighted project plan comparison difficulty, change new design and will become the light-weighted research direction of magnetic clutch.
Model utility content
The purpose of this utility model is to provide a kind of lightweight, and cost is low, and magnetic clutch of good performance.
A kind of Novel lightweight magnetic clutch, comprise the drive plate be connected on compressor shaft, drive plate linking springs sheet, spring sheet connects one group of driver plate, each driver plate is connected with sucker by the rivet of socket elastic rubber column pad, and compressor housing movably connects belt wheel, forms clutch gap between belt wheel end face and sucker card, belt wheel arranges iron core slot, it is characterized in that:
Iron core slot oral area arranges annular spacing groove;
Iron core slot internal ring wall socket iron core shell, iron core shell is arranged the cylindrical shell with iron core slot internal ring wall Spielpassung, cylindrical shell one end arranges fixed tray, fixed tray coordinates with restraining groove bottom land, cylindrical shell is tightly connected coil, coil is positioned at iron core slot, fixed tray connects iron core end cap, and iron core end cap is connected on compressor housing.
Compared with the prior art, the utility model beneficial effect is embodied in:
1. the utility model lightweight magnetic clutch is conducive to reducing car load energy consumption;
2. the utility model lightweight magnetic clutch weight is compared with embryonal structure, declines 8%, has both achieved the lightweight of magnetic clutch, is conducive to again reducing manufacturing cost;
3. the utility model lightweight magnetic clutch decreases the magnetic energy loss of air clearance, is conducive to promoting magnetic clutch torsional performance.
Accompanying drawing explanation

Fig. 3 is pulley structure figure;
Fig. 4 is coil structure.
embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of Novel lightweight magnetic clutch, as shown in Figures 1 and 2, comprise the drive plate 1 be connected on compressor shaft, affixed spring sheet 2 outside drive plate 1, the uniform connection of card three bar shaped driver plates 3 of spring sheet 2, rivet is passed through in spring sheet 2 and each driver plate 3 one end.Driver plate 3 embeds elastic rubber column pad 5, rubber column pad 5 is socketed outer rivet 4, and outer rivet 4 is connected with sucker 6.
As shown in Figure 1, compressor housing connects belt wheel 7 by bearing assemble, forms clutch Spielpassung between belt wheel 7 end face and sucker 6 card.As shown in Figure 3, belt wheel 7 is arranged annular core groove 7a, iron core slot 7a oral area arranges annular spacing groove 7b.
As shown in Fig. 1 and Fig. 4, iron core slot 7a internal ring wall socket iron core shell 9.Iron core shell 9 is arranged the cylindrical shell 9b with iron core slot 7a internal ring wall Spielpassung, cylindrical shell 9b one end arranges fixed tray 9a.Fixed tray 9a coordinates with restraining groove 7b bottom land the relative position limited between iron core shell 9 and belt wheel 7, and as shown in Figure 4, cylindrical shell 9b is by BMC Shooting Technique fixed seal connection coil 8, and coil 8 is positioned at iron core slot 7a.Fixed tray 9a is fixedly connected with iron core end cap 10, iron core end cap 10 is connected by screw on compressor housing.
A kind of Novel lightweight magnetic clutch, as shown in Figure 1, principle summary is as follows:
From motivational drive belt wheel 7 continuous running of motor.Produce magnetic field after coil 8 is energized, after the strengthening of iron core slot 7a internal ring wall, belt wheel 7 and sucker 6 are magnetized, thus makes to produce electromagnetic force between belt wheel 7 and sucker 6, to overcome the elastic force of spring sheet 2 and adhesive.After belt wheel 7 and sucker 6 are fitted, produce frictional force between the two, belt wheel 7 drives sucker 6 to rotate, thus compressor main shaft is driven.When after coil 8 power-off, belt wheel 7, sucker 6 magnetic force disappear, and under the effect of spring sheet 2 elastic force, belt wheel 7 and sucker 6 are thrown off mutually, and compressor shaft runs out of steam.
Described iron core shell 9 is monotubular form, but not adopts bitubular nested form, so just can weight reduction.During installation, fixed tray 9a docks with restraining groove 7b and coordinates, and for small―gap suture coordinates between fixed tray 9a with restraining groove 7b; Restraining groove 7b also can alleviate the weight of belt wheel 7.
Magnetic clutch magnetic line of force closed-loop path of the present utility model is: the magnetic line of force with iron core slot 7a internal ring wall for starting point, by the air clearance between cylindrical shell 9b and iron core slot 7a internal ring wall, be passed to iron core slot 7a internal ring wall, then iron core slot 7a external annulus (i.e. belt wheel 7 outer wall) is directly passed to through fixed tray 9a, and be passed to sucker 6 by iron core slot 7a external annulus by the air clearance between belt wheel 7 and sucker 6, be passed to bottom belt wheel 7 by sucker 6 by clutch gap again, again by being passed to iron core slot 7a internal ring wall bottom belt wheel 7, thus form a closed magnetic loop in clutch inside.
