Description
Technical field
The utility model relates to a kind of electric wheel hub, particularly a kind of brushless gearless wheel deceleration electric wheel hub with rotation input power.
Background technology
Known, miscellaneous, modal common electric wheel hub has wheel hub of electric bicycle, electric tricycle hub and wheel hubs of electric motorcycle both at home and abroad.In common electric wheel hub, DC machine is installed, the power supply of battery-driven car (storage battery) is fixed on vehicle frame, and power supply lead wire maintains static when battery-driven car moves.Exist to connect line length, splicing ear is many, easily damage and aging, and locational space is placed complicated, and how fault the shortcoming such as.There is brushless motor need to regularly replace carbon brush.Without being brushed with tooth motor, owing to there being gear reduction system, complicated structure, easily produces noise.
Utility model content
The purpose of this utility model is that a kind of brushless gearless electric wheel hub with rotation input power will be provided, and solves present electric wheel hub and connects line length, and splicing ear is many, easily damage and aging, and the problems such as inner structure complexity, cancel by carbon brush feed.
The purpose of this utility model is achieved in that this electric wheel hub comprises: axis, end cap, hub shell, wound rotor, magnet steel stator, storage battery, power lead and insulating material; The iron core of magnet steel stator is connected with axis close-fitting, and wound rotor is positioned at hub shell inside, and is connected as a single entity with hub shell, the end cap of hub shell both sides respectively by bearings on axis; Storage battery is fixed by screws on hub shell outer wall, power lead is rotation output, outside face adheres to insulating material, in line outlet groove after via controller from electric motor end cap, pass through, be connected with the winding of magnet steel stator, the bonding magnetic steel of magnet steel stator is on stator core, and Hall element is bonded in slot for winding, and storage battery is connected with the winding of wound rotor; After electrical power, can produce lasting rotary torque, through the electronic commutation of Hall element, produce lasting rotary torque with magnetic steel of stator, drive thus hub shell rotation.
Beneficial effect: owing to having adopted such scheme, wheel hub is shaft type brushless motor.Because of non-carbonate, solved brush motor and need to regularly replace the problem that carbon brush increases service life; Power supply lead wire adds insulating material overcoat, is fixedly connected on winding electric motor end cap and power lead synchronous rotary by motor side cover slot.Compact conformation is simple, reduces motor overall dimensions and weight, improves electrical efficiency, and dependable performance is processed, assembles, keeps in repair all easy and convenient.Be applicable to produce in enormous quantities and reduce production costs.
Advantage:
1, non-carbonate, solve the problem that brush motor needs time-based maintenance or changes carbon brush.
2, power lead rotating feed, rationally utilizes space, dependable performance.
3, gearless deceleration system, simple in structure, reliable.
4, can jointly be assembled in inside wheel with the parts such as power supply, controller, with wheel run-in synchronism, make battery-driven car profile novel, uniqueness, saves space outerpace.
Accompanying drawing explanation
Figure is constructional drawing of the present utility model.
In figure, 1, axis; 2, end cap; 3, hub shell; 4, wound rotor; 5, magnet steel stator; 6, storage battery; 7, power lead; 8, insulating material.
The specific embodiment
Embodiment 1: this electric wheel hub comprises: axis 1, end cap 2, hub shell 3, wound rotor 4, magnet steel stator 5, storage battery 6, power lead 7 and insulating material 8.The iron core of magnet steel stator 5 is connected with axis 1 close-fitting, and wound rotor 4 is positioned at hub shell 3 inside, and is connected as a single entity with hub shell 3, the end cap 2 of hub shell 3 both sides respectively by bearings on axis 1; Storage battery 6 is fixed by screws on hub shell 3 outer walls, power lead 7 is rotation output, outside face adheres to insulating material 8, in line outlet groove after via controller from electric motor end cap 2, pass through, be connected with the winding of magnet steel stator, the bonding magnetic steel of magnet steel stator is on stator core, and Hall element is bonded in slot for winding, and storage battery 6 is connected with the winding of wound rotor; After electrical power, can produce lasting rotary torque, through the electronic commutation of Hall element, produce lasting rotary torque with magnetic steel of stator, drive thus hub shell rotation.
This novel structure uniqueness, reasonable in design, simply compact, dependable performance, processing, assembling, maintenance are all easy, convenient, simple.
