Abstract
The invention discloses a motor stator structure of a hub motor. The motor stator structure is characterized in that several cavities are formed in the inner side of an armature in one circle; a segment of each cavity is used for installing a driving controller of the hub motor, and the driving controller controls operation of the hub motor and monitors and manages the operation state of the hub motor in real time; in the low-speed and large-torque operation state, the heat of the hub motor is dissipated through a cooling flow channel specially designed, and therefore the safe running requirement of an electric car can be met; due to the fact that the work environment of the hub motor is severe and the hub motor needs firm supporting, a bilateral supporting structure is adopted to meet the rigidity requirement of the hub motor; in the design of an inner-side supporting plate, a detachable structure is designed from the aspect of the assembly technique smoothness and maintenance, components having faults during operation can be replaced, and therefore the use cost is lowered.
Description
Technical field
Patent of the present invention is a kind of stator armature structural design of the wheel hub motor for electric automobile.
Background technology
At present, in the new-energy automobile application that the whole world is risen, no matter be oily electric hybrid vehicle, or pure electric automobile, all need two or more lightweight, high-power wheel hub drive motor.Too, country has put into effect the encouragement policy of many new-energy automobiles, saves up strength to start out in new-energy automobile market in China.
Although have a lot of New Product at wheel hub motor design aspect at present, such as: magnetic switch motor, axial motors technical products, has all started the visual field and the market that enter people.These DC motor for vehicles have a common ground at present, are exactly that size is comparatively large, heavier-weight.
According to the growth requirement of new-energy automobile, need a compact conformation, the wheel hub motor of high-power output, and structural strength is large, the complete skill solution of the wheel hub motor stator structure of good rigidly.
Summary of the invention
The object of the invention is to, the technical solution of the stator structure of a brand-new wheel hub motor is provided, adopt thin-wall construction weight reduction, by the Integrated design of various demand, to meet the demand of structural rigidity, rational deployment, to realize the lightweight of wheel hub motor, high-power, the target of high pulling torque design.
For realizing above-mentioned target, a kind of design of brand-new wheel hub motor stator structure is proposed, the design considers the various demands that wheel hub motor is in operation, the reasonable relation having processed coolant flow channel, structural strength, maintainability, reliability, lightweight and drived control integration, in limited size range, utilize space to greatest extent, by the Structural Strength Design of the stator armature of wheel hub motor to relatively high level; Relatively large installing space is left to the drive control component of wheel hub motor and power source bus; Taken into full account the radiating requirements of wheel hub motor in low-speed big operating mode, the radiating flow passage of design, not falling under low intensive condition, alleviates weight, meets the radiating requirements of wheel hub motor armature, achieves hub motor structure compact, the design object that intensity is high.
The feature of this technological invention there are provided a kind of technical products of brand-new wheel hub motor stator armature, the specific demand of new-energy automobile to drive motors can be met, may be used for driving New-energy electric vehicle, the fields such as tank, the popularization for China's new-energy automobile increases a new technical products.
Accompanying drawing explanation
Accompanying drawing is used to provide the further understanding to the technology of the present invention, and forms a part for specification, is used from and explains this technological invention, be not construed as limiting the invention with the examples of implementation one of the technology of the present invention.In the accompanying drawings:
Fig. 1 is work structuring block diagram of the present invention;
In figure: 1, armature support seat 2, armature 3, armature support plate 4, coolant flow channel.
Embodiment
Be described below in conjunction with the preferred embodiment of accompanying drawing to this technological invention, should be appreciated that preferred embodiment described herein is only for instruction and explanation of this technological invention, and be not used in this technological invention of restriction.
According to Fig. 1, the stator armature 2 that this technological invention can realize wheel hub motor be in actual applications arranged on fix with axletree bearing, with on the armature support seat 1 of coolant flow channel 4.The armature support plate 3 shown in FIG plays the support structure effect of stator armature 2 after mounting equally, forms double bracing and improves structural strength.Because this technological invention have employed the integrated design of coolant flow channel 4 and motor stator armature 2 support component, under the prerequisite not lowering structural strength, both met the needs that armature 2 cools, alleviated construction weight again.In cavity between armature support plate 3 and armature support seat 1, electric drive parts and the power source bus of wheel hub motor can be installed.Armature support plate 3 can be taken apart when drive circuit component failure, wheel hub motor is keeped in repair and safeguards.
This technological invention except structure simple, beyond good reliability, can realize the design object of wheel hub motor light-weight design and compact conformation, have very high power-weight ratio, be a kind of technological invention having very much industrialization future.Can be widely used in new-energy automobile field.
Last it is noted that the foregoing is only the preferred embodiment of this technological invention, be not limited to this technological invention, although be described in detail this technological invention with reference to aforementioned drawing, for a person skilled in the art, it still can be modified to the technical scheme described in aforementioned each case study on implementation, or carries out equivalent replacement to wherein portion of techniques feature.Within all spirit in this technological invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection range that all should be included in this technological invention.
