in some embodiments, described permanent magnetism sheet group comprises multiple permanent magnet pieces, and the equidistant also radial arrangement of circumference is inside described driving land.
in some embodiments, described driving land is embedded with the magnetic guiding loop of radial arrangement, described permanent magnetism sheet group is fixed on inside described magnetic guiding loop.Structure is simple, makes clutch configuration compacter further.
in some embodiments, described driving land is sheathed on outside described induction drive plate.
in some embodiments, described coil assembly comprises coil body and is located at the coil of coil body inside, and described coil is electrically connected with external control device.
in some embodiments, connected by plane spring elasticity between described friction disk and described driving land.
in some embodiments, described sucker offers the leakage field groove strengthening described coil assembly adsorptive power.
in some embodiments, described sucker has the absorption wall adsorbing described friction disk.
in some embodiments, respond to drive plate to be directly fixedly connected with sucker.
in some embodiments, described sucker is the sucker be made up of permeability magnetic material.The sucker that permeability magnetic material makes, more easily controls the part of radial dimension, can shorten the distance of permanent magnet induction, and make permanent magnetism slip rotate the foucault current efficiency formed and be improved, transmission is more steady.
the utility model has the advantages that: 1, adjustable electromagnetic clutch of the present utility model, the energy consumption realizing the unnecessary rotation of reduction and cause is combined by the electromagnetic force of the permanent magnetic between induction drive plate and permanent magnetism sheet group and coil assembly, thus realize energy-saving and emission-reduction, reduce environmental pollution; 2, in permanent magnet induction drive mechanism, in induction drive plate, embedded sucker replaces the structure of magnetic guiding loop, forms the permanent magnet transmission induction coil closed, and simplifies clutch component, improves transmission efficiency, makes the structure of product compacter; 3, respond to drive plate be directly fixedly connected with sucker, during adhesive, more strengthen dispelling the heat to friction pair, prevent friction pair because of overheated reduction frictional engagement effect, also thus reduction clutch volume, make the structure of clutch entirety compacter further.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the utility model structure sectional view;
wherein: 1, transmission shaft; 2, coil assembly; 3, drive plate is responded to; 4, sucker; 5, permanent magnetism sheet group; 6, friction disk; 7, plane spring; 8, land is driven.
Embodiment
be below concrete example of the present utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these examples.
as shown in drawings, the utility model is a kind of adjustable electromagnetic clutch, to be arranged on automobile to engine cooling fan.The coil assembly 2 comprising transmission shaft 1 and set gradually from bottom to top, induction drive plate 3, by permeability magnetic material make and have absorption wall sucker 4, be arranged at the permanent magnetism sheet group 5 driven inside land 8, the friction disk 6 that can adsorb mutually with absorption wall or be separated, plane spring 7, drives land 8.Induction drive plate 3 is directly fixedly connected with sucker 4.The fan blades of cooling fan is fixed on and drives on land 8.
permanent magnetism sheet group 5 and the corresponding cooperation of induction drive plate 3, permanent magnetism sheet group 5 comprises multiple permanent magnet pieces, and the equidistant also radial arrangement of circumference is inside driving land 8.Drive magnetic guiding loop land 8 being embedded with radial arrangement, permanent magnetism sheet group 5 is fixed on inside magnetic guiding loop.Land 8 is driven to be sheathed on outside induction drive plate 3.
coil assembly 2 comprises coil body and is located at the coil of coil body inside, and coil is electrically connected with external control device by dragging line.
land 8 is driven to be connected with elasticity between friction disk 6.In the present embodiment, it is preferred for being connected by plane spring 7 elasticity between friction disk 6 and driving land 8.Plane spring 7 is flat, small volume.
sucker 4 offers the leakage field groove of intensifier coil assembly 2 adsorptive power.
sucker 4 is fixedly connected with key with transmission shaft 1; Establish contact Permanent Magnetic Gear transmission mechanism and friction disc pack between sucker 4 and driving land 8, permanent magnetism sheet group 5 and induction drive plate 3 form contact Permanent Magnetic Gear transmission mechanism, and friction disk 6 and plane spring 7 form friction disc pack.
the utility model is rotated by the induction differential of drive plate between permanent magnetism sheet group and forms foucault current and produce permanent magnetic and the coil assembly electromagnetic force produced that is energized and be combined, and realizes the conversion between rotation speed of the fan, to reduce the unnecessary rotating speed of fan.Specific operation principle is as follows:
1, fan slowly runs: when engine water temperature is lower than set temperature, coil assembly 2 is not energized, sucker 4 rotates at full speed with transmission shaft 1, being fixed on the permanent magnetism sheet group 5 driving land 8 is idle, the outside absorption wall of the sucker 4 of at this moment permeability magnetic material making can cut the magnetic field formation foucault current of permanent magnetism sheet group 5 and produce electromagnetic force, the electromagnetic force produced drives and drives the delayed running of land 8 low speed, and this rotating speed general control is about 50% of transmission shaft 1 full speed;
2, fan high speed rotating: when engine water temperature reaches setting temperature, coil assembly 2 is energized, now the coil of coil assembly 2 inside can produce electromagnetic force, the elastic force that the power produced can make friction disk 6 overcome plane spring 7 by adhesive on sucker 4, simultaneously because friction disk 6 is connected with driving land 8 by plane spring 7, thus make sucker 4 can directly drive driving land 8 with the rotating speed high speed rotating with transmission shaft 1 sample, namely fan can rotate at full speed, and engine cooling speed is accelerated.When engine water temperature is lower than the temperature set, coil assembly 2 power-off, electromagnetic force disappears, and the elastic reset power of plane spring 7 can make friction disk 6 be separated with sucker 4, and fan returns to low-speed running state, realizes slowly running.
certain above-mentioned example, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications done according to the Spirit Essence of the utility model main technical schemes, all should be encompassed within protection domain of the present utility model.
