Abstract
The utility model provides a brushless electric hub without an iron core, comprising a housing, a stator, a rotor and a sensor detecting the position of the rotor. The utility model is characterized in that a sun wheel connected with the rotor is engaged with a duplex planet wheel, and another gear wheel in the duplex planet wheel is engaged with an inner gear ring in the housing. The utility model has the advantages that the working efficiency and the bearing capacity are improved, the overloading force moment is large, and the maintenance is convenient, with high reliability; brushless motor is used as a cassette mechanism, with high reliability and convenient maintenance, the volume is small, and the weight is light; besides, the noise is low.
Description
Technical field
The utility model relates to a kind of no iron core brushless electric wheel hub, is mainly used in to drive Electrical Bicycle or motor bike.
Background technology
In recent years, the Electrical Bicycle speed of development is very fast, wherein, drive motor is one of bottleneck of its performance raising of restriction, and Chinese patent discloses a kind of permanent magnetic brushless as electric vehicle hub for No. 96234911.9, it comprises the sensor of housing, stator, rotor and detection rotor position, problem is that its efficient is lower, improve moment of torsion, also need increase the quantity of commentaries on classics, stator, so not only strengthened the volume of wheel hub, returned follow-up maintenance and make troubles.
The utility model content
The purpose of this utility model provides a kind of no iron core brushless electric wheel hub, and it is by being integrated in motor and transmission device in the wheel hub, thereby can improve its efficient and load-carrying capacity effectively.
The technical scheme that realizes the utility model purpose is: a kind of no iron core brushless electric wheel hub, the sensor that comprises housing, stator, rotor and detection rotor position, it is characterized in that: sun wheel is connected with rotor, is meshed with the internally toothed annulus of housing with another gear in the double-planetary gear that sun wheel is meshed.
And, can be provided with 2～5 satellite gears that are meshed with sun wheel.
And satellite gear can be a plastic gear.
And sensor can be a HALL-IC.
The advantage of the technical program is: 1. can increase work efficiency and load-carrying capacity, overload torque is big; 2. adopt brushless motor to make movement, the reliability height is convenient to safeguard; 3. volume is little, in light weight, and noise is low.
Description of drawings
Accompanying drawing is the integrally-built cutaway view of signal the utility model.
The specific embodiment
With reference to accompanying drawing, below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, this electric wheel hub comprises: the sensor 12 of housing 3, stator 6, rotor 5 and detection rotor 5 positions, its improvement is: sun wheel 8 is connected with rotor 5, is meshed with the internally toothed annulus 11 of housing 3 with another gear 10 in the double-planetary gear 9 that sun wheel 8 is meshed.
Housing 3 outer rings of described wheel hub are provided with the hole 4 that connects width of cloth bar, housing 3, width of cloth bar and the wheel rim of wheel hub can certainly be made one.Lead 1 can be introduced from an end of actionless axis 2.
Described internally toothed annulus 11 can be connected with housing 3 bolts 7, also the two can be made one.
Further technical scheme can be: be provided with 2～5 satellite gears 9 that are meshed with sun wheel 8.Specifically can select according to the parameter working condition, but 3 satellite gears 9 preferably.Adopt this planet transmission device will have advantages such as volume is little, messenger chain is short, speed ratio is big.
Further technical scheme can also be: satellite gear 9 can be a plastic gear.This will help cost-cutting, reduce noise.
Sensor 12 can be a HALL-IC.This element can be buied from market.Its effect is to send signal to control setup, to change the "on" position of armature loop, rotor 5 is rotated continuously.
Motor adopts no iron core brushless and plate-like stator and rotor structure, and this will help reducing machine volume and weight, is convenient to safeguard and the raising complete machine is exerted oneself.
