Abstract
The utility model relates to a high speed motor hub for an electric bicycle, and belongs to the technical field of an electric bicycle. The high speed motor hub for the electric bicycle comprises a motor, a main shaft and a hub cap. The motor is assembled on the main shaft, adopts an internal stator external rotor structure, and is externally assembled with the hub cap. The 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, and the internal gear ring is assembled on the motor hub cap by a bearing. The high speed motor hub has the advantages of simple and compact structure, high motor efficacy, low power consumption and gear abrasion of the gear, convenient installation, comfortable riding, low noise, long service life, and the like.
Description
Technical field
The utility model belongs to the electric bicycle technical field, particularly relates to a kind of electric bicycle high-speed electric expreess locomotive 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 gear, freewheel clutches, motor generally 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, causes the problem such as uncomfortable of riding.
Summary of the invention
The utility model provides a kind of electric bicycle high-speed electric expreess locomotive 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, the electric bicycle high-speed electric expreess locomotive wheel hub of characteristics such as easy for installation, it is comfortable to ride, and noise is low, and the life-span is long.
The utility model adopts following technical scheme:
Electric bicycle high-speed electric expreess locomotive wheel hub, comprise motor, main shaft, hubcap, motor is assemblied on the main shaft, and motor adopts the internal stator outer-rotor structure, is equipped with hubcap outward, be characterized in: planetary gear carrier is installed on the main shaft, planetary gear is installed on the planet axis, and the planetary gear outside engages with inner gear ring, and planetary gear is inboard to be meshed with central gear, central gear is installed on the rotor, and inner gear ring is assemblied on the motor wheel hub cover by bearing.
The utility model can also be taked following technical measures:
Described electric bicycle high-speed electric expreess locomotive wheel hub is characterized in: planetary gear has 3, and central gear meshes all planetary gears.
Described electric bicycle high-speed electric expreess locomotive wheel hub is characterized in: planetary gear by Bearing Installation on support.
Described electric bicycle high-speed electric expreess locomotive wheel hub, be characterized in: inner gear ring is installed in the unilateral bearing inboard, and unilateral bearing is fixed on the motor wheel hub cover, and inner gear ring can only one-directional rotation.
Advantage that the utlity model has and good effect:
Electric bicycle high-speed electric expreess locomotive wheel hub has adopted technical solutions of the utility model, compares with the prior art training, the utlity model has following characteristics:
1, motor adopts the internal stator outer-rotor structure, does not adopt freewheel clutch, cooperates planetary gear reducing mechanism to finish deceleration with the one-directional rotation ring gear, has improved the effect of motor.
2, at the reversing state, unilateral bearing rotates, and inner gear ring does not drive planetary gear and rotates, and it reduces energy consumption and gear wear, long service life.
3, this wheel hub structure is simple, compact, and drive disk assembly is few, and is easy for installation, safe and reliable etc.
