Abstract
The utility model relates to a brushless toothed high speed motor hub for an electric bicycle, and belongs to the technical field of an electric bicycle. The brushless toothed high speed motor hub for the electric bicycle comprises a motor, a main shaft and a hub cap. The motor adopts an internal stator external rotor structure and is externally assembled with the hub cap. The brushless toothed high speed motor hub is characterized in that a planet gear supporting frame is mounted on the main shaft, a planet gear is mounted on a planet shaft, the outer side of the planet gear is meshed with an internal gear ring, the inner side of the planet gear is meshed with a sun gear which is mounted on a motor rotor with a brushless structure, and the internal gear ring is fixedly mounted on the motor hub cap. The brushless toothed high speed motor hub has the advantages of simple and compact structure, small volume, high motor efficacy, convenient installation, low noise, long service life, low cost, and the like.
Description
Technical field
The utility model belongs to the electric bicycle technical field, and particularly relating to a kind of electric bicycle does not have the tooth depth of being brushed with speed motor wheel hub.
Background technology
At present, how existing electric bicycle high-speed electric expreess locomotive wheel hub is formed with parts such as main shaft, wheel hub shell, rotor, stator, reducing gears, motor adopts the internal stator outer-rotor structure, because drive disk assembly complexity, many parts all are independent parts, have only when combination structure closely could reduce energy consumption, but along with the increase of gear wear degree, the structure tightness descends, and has a strong impact on the useful life of motor; And reducing gear adopts planetary gear structure more, no matter is that motoring condition or manpower are ridden and the reversing state, and all in running, gear wear is very fast for central gear and planetary gear, and noise is bigger, and efficient is not high, and it is uncomfortable etc. to ride.
Summary of the invention
The utility model provides a kind of electric bicycle not have the tooth depth of being brushed with speed motor wheel hub for solving the problem that existing known technology exists.
The purpose of this utility model provide a kind of have simple in structure, compact, motor effect height, easy for installation, the electric bicycle of characteristics such as it is comfortable to ride, and noise is low, and the life-span is long, and cost is low does not have the tooth depth of being brushed with speed motor wheel hub.
The utility model adopts following technical scheme:
A kind of electric bicycle does not have the tooth depth of being brushed with speed motor wheel hub, comprise motor, main shaft, hubcap, motor adopts the internal stator outer-rotor structure, be equipped with hubcap outward, be characterized in: planetary gear carrier is installed on the main shaft, and planetary gear is installed on the planet axis, the planetary gear outside and inner gear ring engagement, planetary gear is inboard to be meshed with central gear, and central gear is installed on the rotor, and the motor wheel hub cover installs inner gear ring.
The utility model can also be taked following technical measures:
Described electric bicycle does not have the tooth depth of being brushed with speed motor wheel hub, and be characterized in: planetary gear carrier is fixed on the main shaft.
Advantage that the utlity model has and good effect:
Electric bicycle does not have the tooth depth of being brushed with speed motor wheel hub and has adopted technical solutions of the utility model, compared with prior art, the utlity model has following characteristics:
1, this wheel hub adopts the internal stator outer rotor brushless motor, does not adopt freewheel clutch, has improved the effect of motor.
2, this wheel hub structure is simple, compact, and drive disk assembly is few, and is easy for installation, safe and reliable etc.
3, little, the motor effect height of this wheel hub volume, easy for installation, noise is low, and the life-span is long, and cost is low etc.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure, 1-main shaft, 2-central gear, 3-inner gear ring, 4-hubcap, 5-end cap, 6-bearing, 7-stator, 8-rotor, 9-planetary gear, 10-planet axis, 11-support.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
