Abstract
The utility model discloses a spoke-type low-speed brushless DC (direct current) electric hub. A motor shaft of the electric hub is connected at the circle centers of a left hub cap and a right hub cap through a left hub cap bearing and a right hub cap bearing. A motor outgoing line is led out through a center hole of the motor shaft. The left hub cap and the right hub cap are combined into a hub cap shell.both the inner side walls of the left hub cap and the right hub cap are provided with corresponding positioning key pins and magnetic conductive rings. A stator bracket is connected with the motor shaft through a flat key. The stator bracket is provided with a stator winding. An iron core and a magnetic steel are arranged in the hub cap shell. The spoke-type low-speed brushless DC electric hub has the advantages that the electric hub has compact inner structure; the structure is simple and light; the weight of the motor is furthest reduced; the left hub cap and the right hub cap are firmly and reliably adhered; a matching and connecting space of the left hub cap and the right hub cap is saved; materials are saved; fussy processing and assembling processes are reduced; the assembling efficiency is improved; and the cost of the motor is reduced, so that the motor has effects of smaller gear opening, low fault rate and lighter weight on the premise that the performance is reduced.
Description
Technical field
The utility model relates to the electric wheel hub that a kind of Electrical Bicycle uses, particularly a kind of spoke type brushless electric wheel hub.
Background technology
Present common brushless gearless low speed electric wheel hub is because housing, stator, rotor and motor hub cap constitute, and fixing of motor hub cap wherein and housing all is to adopt screw that hub cap and housing are fixed as one; Perhaps the motor hub cap is fixed with the fit system that adopts screw thread to screw that is connected of housing.The shortcoming of these two kinds of fixing modes is that fit structure takes up room greatly, and stock utilization is low; Assembly process is many, loaded down with trivial details, and complex process, efficiency of assembling are low; Motor productive costs height.
The utility model content
Order of the present utility model ground is to provide a kind of: spoke type brushless electric wheel hub, and solve the electric wheel hub fit structure and take up room greatly, stock utilization is low; Assembly process is many, loaded down with trivial details, and complex process, efficiency of assembling are low; The problem that the motor productive costs is high.
The purpose of this utility model is achieved in that this electric wheel hub comprises left hub cap bearing, motor shaft, the motor pig-tail wire, stator support, left side hub cap, stator winding, the location key pin, magnetic guiding loop, magnet steel, iron core, right hub cap, flat key, right hub cap bearing, motor shaft is connected the circle centre position of left hub cap and right hub cap by left hub cap bearing and right hub cap bearing, the motor pig-tail wire is drawn by the centre hole of motor shaft, left side hub cap and right hub cap synthesize the hub cap housing, on left hub cap and right hub cap madial wall, be evenly equipped with cooresponding location key pin and magnetic guiding loop, stator support is connected with motor shaft by flat key, stator winding is arranged, cored and magnet steel in the hub cap housing on stator support.
Beneficial effect, owing to adopted such scheme, the left hub cap and the right hub cap of electrical motor wheel hub synthesize the hub cap housing, a left side hub cap and right hub cap adopt the positioning bonding fit, fix or screw thread screws fixed form and saved the space, reduced material usage, reduced assembly cost, improved efficiency of assembling than screw.Adopted special adhesive glue, guaranteed motor under actual running condition, left hub cap and right hub cap have enough anchoring strengths and weather resisting property.
Solved the electric wheel hub fit structure and taken up room greatly, stock utilization is low; Assembly process is many, loaded down with trivial details, and complex process, efficiency of assembling are low; The problem that the motor productive costs is high.Reach the purpose of this utility model.
Advantage: this electric wheel hub has adopted light-duty stator core and mandrel, inner structure compactness, simple structure, light, reduced the weight of motor to greatest extent, a left side hub cap and right hub cap are bonding solid and reliable, have saved left hub cap and the right hub cap space that is connected, and have saved material; Reduce loaded down with trivial details processing, assembly process, improved efficiency of assembling; Reduced motor cost, made motor under the prerequisite that does not reduce performance, accomplished to open shelves littler, fault rate is low, weight is lighter.
