A small -size unilateral axle in -wheel motor, includes the hub shell body, unilateral stretching out the motor shaft of the hub shell body and one with the fixed winding motor stator who links to each other of above -mentioned motor shaft, winding motor stator includes iron core, enamelled coil and magnet steel, be equipped with the rule groove in the magnet steel, the embedding has enamelled coil in the rule groove, the hub shell body includes upper end cover and the hub casing who takes the bottom end cover, hub casing and bottom end cover structure as an organic whole, upper end cover and hub casing threaded connection. The utility model discloses compare with the prior art product, hub casing and bottom end cover structure as an organic whole, simple structure, the cost of manufacture is low, upper end cover and hub casing threaded connection, it is more convenient, practical to install.
Description
Technical field
The utility model relates to machine field, especially a kind of small-sized single side axis wheel hub motor.
Background technology
Along with the reinforcement of social environment consciousness and the development of modern science and technology, one is referred to as the power truck of " green traffic instrument ", more and more by concern and the favor of people. Universal and the development of power truck provides a kind of safety and comfort, the vehicles efficiently pollution-free without noise, light and handy to people undoubtedly.
Making a general survey of the electronic bike of all kinds that existing market is released, its electric motor generally adopts common wheel hub direct-current motor. Motor casing rotates, and becomes the wheel of power truck with spoke or wheel hub, and motor both sides spindle nose stretches out fixing.
Patent No. ZL200620133210.9 discloses a kind of unilateral axle hub motor of motor vehicle, and motor shaft is monolateral to be stretched out, the other side of motor shaft, and spindle nose does not stretch out outside lower end cover, and lower end cover center has hole, seals lower end cover centre hole with decorative dustproof cover. Although comparing common wheel hub direct-current motor to have saved cost of manufacture, but owing to being monolateral motor, so lower end cover not perforate can be considered, it is even possible that lower end cover and hub shell are arranged to integrative-structure, convenient installation, as for keeping in repair and be that lubricating grease noted by bearing, structure is simple, also can not difficulty.
Practical novel content
The technical problems to be solved in the utility model is: based on the problems referred to above, it is provided that a kind of structure is simpler, install more convenient, practical small-sized single side axis wheel hub motor.
The utility model solves the technical scheme that its technical problem adopts: a kind of small-sized single side axis wheel hub motor, comprise a hub shell, the one monolateral motor shaft and one and the winding electric machine stator that is fixedly linked of above-mentioned motor shaft stretching out described hub shell, described winding electric machine stator comprises iron core, enameled wire loop and magnet steel, described magnet steel is provided with line embedding groove, described line embedding groove is embedded with enameled wire loop, described hub shell comprises upper end cover and the hub shell of band lower end cover, described hub shell and lower end cover are structure as a whole, described upper end cover is threaded with hub shell.
Further, described hub shell is connected on motor shaft by upper and lower bearing, and the diameter of lower bearing is less than the diameter of head bearing.Owing to the lower bearing of motor shaft is arranged on lower end cover, so in order to cost-saving, lower bearing can by a little model.
Further, one end of described motor shaft is fixed in lower bearing by jump ring. Hub shell is stretched out owing to motor shaft is monolateral, so in order to ensure the stability that motor shaft is installed, it is necessary to fastening piece is set, such as jump ring.
Further, described hub shell is provided with tire.
The beneficial effects of the utility model are: the utility model is compared with prior art products, and hub shell and lower end cover are structure as a whole, and structure is simple, and cost of manufacture is low; Upper end cover is threaded with hub shell, installs more convenient, practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is illustrated further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the explosive view of Fig. 1.
In figure: 1. motor shaft, 2. iron core, 3. enameled wire loop, 4. magnet steel, 5. upper end cover, 6. hub shell, 7. head bearing, 8. descend bearing, 9. jump ring, 10. tire, 4-1. line embedding groove, 6-1. lower end cover.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now. These accompanying drawings are the schematic diagram of simplification, only with illustration, basic structure of the present utility model are described, therefore it only shows the formation relevant with the utility model.
As shown in Fig. 1～2, a kind of small-sized single side axis wheel hub motor, comprise a hub shell, a monolateral motor shaft 1 and one and the winding electric machine stator that is fixedly linked of above-mentioned motor shaft 1 stretching out described hub shell, winding electric machine stator comprises iron core 2, enameled wire loop 3 and magnet steel 4, magnet steel 4 is provided with line embedding groove 4-1, line embedding groove 4-1 is embedded with enameled wire loop 3, hub shell comprises upper end cover 5 and the hub shell 6 of band lower end cover 6-1, hub shell 6 and lower end cover 6-1 are structure as a whole, and upper end cover 5 is threaded with hub shell 6. In addition, hub shell is connected on motor shaft 1 by upper and lower bearing 7,8, and the diameter of lower bearing 8 is less than the diameter of head bearing 7. One end of motor shaft 1 is fixed in lower bearing 8 by jump ring 9.
Hub shell 6 is provided with tire 10.
Certainly, in order to improve maintenance further and be the problem of lower bearing 8 note lubricating grease, it is possible to design lower end cover 6-1 and be threaded with hub shell 6, block to link and connect.
Taking above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff in the scope not deviateing this practical new technique thought, can carry out various change and amendment completely. The content that the novel technical scope of this practicality is not limited on specification sheets, it is necessary to determine its technical scope according to right.
