Abstract
An electric hub is the center member of an electric vehicle, and the performance of the electric hub influences the development of the electric vehicle directly. The present invention relates to a brushless non-core electric hub which has no iron core, the internal resistance of a stator coil is extremely little, and thus, the electric hub has high efficiency and low heat productivity. In addition, the electric hub has the advantages of compact structure, small size, good dynamical capacity and good heat balance condition. The electric hub is particularly suitable for manufacturing high capacity and high efficiency electric vehicles (such as electric bicycles, electric motor cars, electric automobiles, electric wheelchairs, etc.).
Description
Technical field
The present invention relates to a kind of electric wheel hub, especially a kind of brushless coreless electric wheel hub.Electric wheel hub is the core component of motor vehicle, and whether the advanced person will directly have influence on further developing of motor vehicle to its performance.
Background technology
Adopt of present electric wheel hub is brushed with iron core axis version more, and following shortcoming is arranged: have brush to cause the failure rate height, the cored efficient that causes is low, and axis causes the electric wheel hub radial dimension excessive.
For overcoming above-mentioned shortcoming, the present invention proposes a kind of brushless coreless electric wheel hub.This electric wheel hub does not have iron core, and the stator coil internal resistance is minimum, and therefore, this electric wheel hub is the efficient height not only, and caloric value is extremely low.In addition, this electric wheel hub compact conformation, size is little, dynamic characteristics good, the heat balance condition is good, is particularly suitable for making high-performance, high efficiency motor vehicle (electric bicycle, battery-operated motor cycle, electric automobile, electric wheelchair etc.).
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcoming that is brushed with iron core axis version is arranged, and promptly has brush to cause the failure rate height, and the cored efficient that causes is low, and axis causes the electric wheel hub radial dimension excessive.
Technical scheme of the present invention is:
The central shaft of electric wheel hub is divided into three sections, i.e. left side axle, axis and right axle.On the axle of a left side, be fixed with planetary carrier, three turriform gears are housed on it, and the turriform gear is connected to form with one heart by small one and large one two gears, and the pinion of turriform gear is meshed with the imperial palace Knucle-gear, the cylindrical of imperial palace Knucle-gear is fixedlyed connected with the wheel hub shell, and the wheel hub shell links to each other with tire.The left end of axis is meshed by the gear wheel of external tooth with the turriform gear, and right-hand member is connected with motor outer rotor.Admittance line in the right axle, lead is connected with the stator coil that is fixed on right, and the motor outer rotor of band permanent magnet is housed on the bearing on right axle both sides, and motor outer rotor is connected with the right-hand member of axis.With stator coil that the right axle of electric wheel hub links to each other outside be provided with motor outer rotor, motor outer rotor is made by the iron material, be fixed with on the internal rotor axial end outside some to permanent magnet, by attracting each other and supporting and keep suitable air gap with stator coil by right axle.Stator coil does not have core structure for the wire-wound disc type, drives the motor outer rotor that is supported on the right axle and rotate and power output when energising.
Owing to designed the turriform gear, make the radial dimension of electric wheel hub of the present invention dwindle greatly, this measure can improve the power density and the rigidity of electric wheel hub greatly.
The invention has the beneficial effects as follows:
1) brushless, so the reliability height.
2) therefore no iron core does not have iron loss.
3) internal resistance of disc type stator coil is extremely low, so caloric value is little.
4) two-sided yoke can be gathered magnetic by the iron motor housing, has improved the magnetic energy utilization rate.
5) electric efficiency height.
6) the output torque is big.
7) no slot effect.
8) rotating speed is steady.
9) use the turriform gear, radial dimension is little, no-load voltage ratio is big.
10) hub rigidity is big.
