Description
Technical field
The utility model relates to a kind of generator, relates to the electric automobile wheel permanent-magnet generator specifically.
Background technology
Prior electric car, battery-operated motor cycle are typically equipped with for example storage battery etc. of outside electric energy storage device, must provide the power of vehicle operating to use by electric energy storage device earlier to after the electric energy storage device charging in use.So; The distance that electric motor car, battery-operated motor cycle go just receives the restriction of the accumulate capacity of outside electric energy storage device; Therefore caused many inconvenience to the user; Electric energy in the for example in a single day outside electric energy storage device is used up, and so just must use manpower to replace, and has lost original purpose of electric motor car utility model.Also occurred in the prior art generator is used on the driven pulley of electric motor car, battery-operated motor cycle and addressed the above problem, made vehicle in the process of running, utilized generator for electricity generation to come, not only cleaned but also energy savings to the electric energy storage device charging.At present the generator of extensive use mainly be two kinds of permanent magnet generator and excitation generators in practice, and the maximum of permanent magnet generator and excitation generator is distinguished and 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, has avoided excitation winding to be prone to burn, break, carbon brush, slip ring structure; Complete machine structure is simple; Avoided excitation-type generator excitation winding to be prone to burn, break, fault such as carbon brush, slip ring are easy to wear, reliability greatly improves.But the permanent magnet generator that is used on the driven pulley of the prior art also exists the low problem of energy utilization rate.
Summary of the invention
The technical problem that the utility model will solve provides the electric automobile wheel permanent-magnet generator of a kind of environmental protection science, energy savings.
For solving above-mentioned utility model purpose; The electric automobile permanent magnet generator of the utility model mainly adopts a kind of like this structure: it comprises internal stator and external rotor; Stator core is packed on the axletree through stator support, and winding coil has constituted internal stator on stator core; The outside at internal stator; The corresponding overcoat rotating disk that is provided with internal stator; Be provided with bracing means in described overcoat rotating disk both sides; Described bracing means also overcoat rotating disk cooperates together, and through bearing fixing on described axletree, correspondence is provided with magnet assembly and has constituted external rotor on the inwall of its external sleeve rotating disk.
As the further improvement of the utility model, described bracing means is for reinforcing Pan Jia and reinforcing dish second.Because the electric automobile axletree permanent magnet generator that is arranged so that the utility model of reinforcing dish is firm more, safety.
As the further improvement of the utility model, described stator core is the multiple-grooved iron core.Design makes the power of permanent magnet generator more strengthen like this.As the further improvement of the utility model, described magnet assembly is a rare-earth permanent magnet steel.Because rare-earth permanent magnet steel has the magnetic property height, has strengthened the energy of magnetic circuit system, thereby has further improved the electricity generation efficiency of the wheel butterfly permanent magnet generator of the utility model.
As the further improvement of the utility model, the power supply output line of described winding coil is drawn through axletree, is connected with outside electric energy storage device.Make that like this structural design of electric automobile axletree permanent magnet generator of the utility model is more reasonable, compactness.
The electric automobile axletree permanent magnet generator of the utility model, compact conformation, reasonable in design, the environmental protection science has very big promotion and application and is worth.
Description of drawings
Fig. 1 shows the cutaway view of the utility model.
Embodiment
Below in conjunction with Figure of description the electric automobile axletree permanent magnet generator of the utility model is done further detailed explanation.
Fig. 1 shows the cutaway view of electric automobile axletree permanent magnet generator of the present invention.It comprises internal stator 1 and external rotor 2, and stator core 11 is packed on the axletree 3 through stator support 12, and winding coil 13 has constituted internal stator 1 on stator core 11; The outside at internal stator 1; With the internal stator 1 corresponding overcoat rotating disk 21 that is provided with; Be provided with bracing means 4 in described overcoat rotating disk 21 both sides; Described bracing means 4 also overcoat rotating disk 21 cooperates together and covers internal stator 1, and is fixed on the described axletree 3 through bearing 5, and correspondence is provided with magnet assembly 22 and has constituted external rotor 2 on the inwall of its external sleeve rotating disk 21.Described bracing means is the left side reinforcing dish 41 and right reinforcing dish 42 that is arranged on overcoat rotating disk 21 both sides; Reinforcing dish 41,42 and overcoat rotating disk 21 are combined into a tray type structure about described; Cover internal stator 1; On the inwall of said overcoat rotating disk 21, be provided with magnet assembly 22, overcoat rotating disk and magnet assembly are combined and have been constituted external rotor 2; Reinforcing dish 41,42 is connected on the axletree 3 through bearing about described, and can be around axletree 3 rotations.
Electric automobile axletree permanent magnet generator one side of the utility model is connected with brake block 5 through muscles and bones screw 5; Opposite side is connected on the driven pulley of electric automobile through screw 6; Be pulled in the process of going at driven pulley; Said external rotor 2 is answered the line motion and is produced electric energy thereby make internal stator 1 do cutting magnetic induction with respect to external rotor 2 along with the rotation on ground of the rotating tire 5 of driven pulley, has saved need external impetus to provide loaded down with trivial details; Be equal to the rotation that directly drives external rotor by the rotation of driving wheel drive driven pulley, simple and convenient.
Further improvement as the utility model; Said magnet assembly 22 selects rare-earth permanent magnet steel as magnetic source; Mainly be to have utilized the high characteristics of thulium permanent magnet magnetic property; Strengthen the energy of magnetic circuit system, thereby further improved the electricity generation efficiency of the wheel butterfly permanent magnet generator of the utility model.
