Description

Wheel permanent-magnet generator
Technical field
The present invention relates to a kind of generator, particularly relate to a kind of automobile, electric motor car or hybrid power wheel generator.
Background technology
Two kinds of the main permanent magnet generator of generator of present extensive use in practice and excitation generators, the maximum difference of permanent magnet generator and excitation generator is that its excitation field is produced by permanent magnet.And the permanent magnet in the permanent magnet generator is magnetic source in generator, is again the part of magnetic circuit.Magneto-electric generator has saved excitation winding, carbon brush, the slip ring structure of excitation-type generator, complete machine structure is simple, avoided excitation winding easily to burn, break, carbon brush, slip ring structure, complete machine structure is simple, avoided excitation-type generator excitation formula generator excitation winding easily to burn, break, fault such as carbon brush, slip ring are easy to wear, reliability greatly improves.Nowadays a kind of permanent magnet generator of extensive use is called the external rotor disk generator in practice.Referring to Fig. 1, it mainly adopts following this structure the external rotor disk generator, and the stator of generator and rotor are arranged in the little tray type structure of the ratio of major diameter, rotor outside, stator is interior; Be fixed with aluminum frame on one fixed axis, support the multiple-grooved iron core,, and, constitute internal stator with magnetic slot-seal filling multiple-grooved iron core notch at the embedded system fractional turn coil of multiple-grooved iron core; The left and right outside at internal stator, front and rear cover is arranged respectively by left and right sides bearing, be connected with fixed axis, and can rotate around fixed axis, front and rear cover plate connects with the aluminium casing, and be covered in internal stator, the inboard corresponding internal stator relative position of aluminium casing adopts the magnet steel structure of multistage diametrical magnetization, at the magnet steel radial outside magnetic guiding cycle is arranged, in the magnet steel inboard damper is housed radially, and forms external rotor with the aluminium casing.But the permanent magnet generator that adopts this structure must provide extra power to drive, for example wind, water, electric energy etc.; And because permanent magnet motor lacks necessary protective device, fixedly use can not be used in the vehicles, for example on automobile or the hybrid vehicle.
Summary of the invention:
The technical problem that the present invention solves is: a kind of compact conformation is provided, energy savings, environmental protection science, can directly be used in the permanent magnet generator that uses on various automobiles or the hybrid vehicle.
For solving the problems of the technologies described above, the invention provides a kind of wheel permanent-magnet generator, it comprises wheel and permanent magnet generator, described wheel comprises axletree and hub, it is characterized in that: described wheel is the driven pulley on the vehicles; Cooperate on the described hub wheel housing-plate is housed; Described permanent magnet generator mainly comprises internal stator and external rotor, and described internal stator is fixed on hub and the axletree of wheel between the housing-plate; Described external rotor and internal stator are corresponding, place the inwall of hub; The power supply output line of winding coil passes axletree and is connected with external charging equipment.This kind wheel permanent-magnet generator can be used on the driven pulley of automobile or hybrid vehicle, and the external rotor that is driven on the wheel permanent-magnet generator by wheel rotates, thereby generation electric energy, can generate electricity environmental protection science, energy savings not needing to provide separately under the powered attendant-controlled wheelchairs condition; This patent is convenient to install and safeguard also specially for wheel has been equipped with cap, also is provided with sealing ring at axletree two end cap place in addition, thereby generator has been played the effect of seal protection.
As a kind of improvement of the present invention, described stator is connected with axletree by stator support; One end of described stator support is fixed on the axletree, and the other end links to each other with stator.Make the winding coil and the external rotor of stator mate more like this, thereby produce better production capacity effect.
As another improvement of the present invention, bearing is located between hub, wheel cap and the axle, and oil sealing is arranged on the bearing outside, utilize bearing can guarantee axletree rotate more smooth and easy, oil sealing has then guaranteed sealing, thereby has created better operational environment to generator.
As a further improvement on the present invention, the external rotor inwall is provided with thulium permanent magnet.What this programme adopted is rare-earth permanent magnet steel, makes the generated output of generator stronger.
Description of drawings:
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is an external rotor desk permanent-magnet generator
Fig. 2 is the cutaway view of invention wheel permanent-magnet generator.
Embodiment
Fig. 2 shows first kind of execution mode of the present invention.Wheel permanent-magnet generator of the present invention comprises wheel and permanent magnet generator, and described wheel comprises axletree 1 and hub 2, and described wheel is a driven pulley; Cooperate on the described hub wheel housing-plate 21 is housed; Described permanent magnet generator mainly comprises internal stator 3 and external rotor 4, and described internal stator 3 is fixed on hub 2 and the axletree of wheel between the housing-plate 21 1; Described external rotor 4 is corresponding with internal stator 3, places the inwall of hub 2; The power supply output line 32 of winding coil 31 passes axletree 1 and is connected with outside electric energy storage device.Adopt the wheel permanent-magnet generator of this kind structure, owing to be mounted on the driven pulley of electric motor car or hybrid vehicle, be pulled in the process of travelling at driven pulley, the described external rotor 4 that is arranged on hub 2 inwalls is along with the rotation on ground of the rotating tire 5 of driven pulley, thereby making internal stator 3 do cutting magnetic induction with respect to external rotor 4 answers the line motion and produces electric energy, need external impetus to provide loaded down with trivial details has been provided, be equal to the rotation that directly drives external rotor by the rotation of driving wheel drive driven pulley, simple and convenient.Meanwhile,, wheel permanent-magnet generator can be used on the hub of various vehicles, enlarge the range of application of wheel permanent-magnet generator because the setting of wheel housing-plate 21 makes permanent magnet generator be convenient to install and safeguard.
As further improvement of the utility model, stator is connected with axletree 1 by stator support 32, after adopting this structure, make that the winding coil 31 of son is nearer apart from external rotor, thereby magnetic flux density is higher, make the winding coil 31 of stator 3 mate more like this, thereby improved wheel generator production capacity effect with external rotor 4.
As a kind of improvement of the present invention, compare with preceding two kinds of execution modes, bearing 11 is located between hub 2, wheel cap 21 and the axle 1, bearing 11 outsides are provided with oil sealing 12.Oil sealing 12 is arranged on bearing 11 outsides, because bearing 11 can make the more smooth and easy of axletree rotation, 12 on oil sealing has guaranteed sealing, thereby has created better operational environment to generator.
Further improve as of the present invention, rare-earth permanent magnet steel 41 is arranged on the external rotor inwall.Selecting rare-earth permanent magnet steel as magnetic source, mainly is to have utilized the high characteristics of thulium permanent magnet good magnetic performance, has strengthened the energy of magnetic circuit system, thereby has further improved the electricity generation efficiency of wheel generator.
