Description
Technical field
The present invention relates to field of automobile, specially a kind of electromechanical energy-saving axial magnetic flux for electric vehicle
Motor.
Background technique
The rapid development of auto industry has greatly pushed the technological progress of the mankind and the hair of economic society etc.
Exhibition, but automobile also brings very big drawback while promoting the well-being of mankind, wherein environmental pollution and energy consumption have become
The target of public criticism.Pollution caused by internal-combustion engines vehicle is got worse, and tail gas, noise and tropical island effect etc. are destroyed caused by environment
Through to the degree that must be controlled and administer.Especially some populous, congested in traffic big and medium-sized cities situations more
Seriously.Simultaneously internal-combustion engines vehicle be using the non-renewable natural resources of the preciousness such as incendiary oil, natural gas as power, and it is interior
The low efficiency of combustion engine, it is greatly to waste that these natural resources are directly burnt up as fuel, according to statistics if disappeared according to current
Speed is consumed, the natural resources such as petroleum, natural gas are only capable of maintaining the time of many decades again.Environmental pollution caused by internal-combustion engines vehicle and
Consumption to resource greatly threatens the health and existence of the mankind.
Electric vehicle is the urban transportation tool of 21 century clean and effective, is Vehicle Engineering, electric drive technology, electronics skill
The integrated product of newest fruits in the engineering technology such as art, intelligent control, chemical energy source, computer, new material.Electric vehicle is with electric power
For power, it may be achieved the diversification configuration of the energy relieves people's worry increasingly depleted to petroleum resources；As clean new
The type vehicles, when driving can be without discharge or low emission；It is excellent also to have that structure is simple, working service facilitates etc. for electric vehicle simultaneously
Point, therefore cause the common concern of people and greatly developed.
Traditional vehicle bridge and either " two-in-one " still " three-in-one " still " the more conjunctions of its thinking of electric drive axle Integrated Solution
One ", it is at all exactly system integration, lightweight and miniaturization.But it takes turns itself or wheel, also needs between two wheels
Want axle to connect, only whether its axle is simple axle or is integrated with the other parts such as motor, front and back axle it
Between there is also mechanical connections as needed.This structure type, the presence of axle constrains the fortune of two sides wheel in essence
Dynamic, angle range is restricted, and the especially big multi-vehicle-type of rear wheel does not have corner characteristic.Existing power decentralized type driving electricity
Machine, that is, hub motor, regardless of the working principle of type, be all from conventional motors type evolution, that is,
The traditional radial flux design scheme used, centered on machine shaft, one is radial outer circle for motor stator and rotor
Another is radial interior garden, and this electric machine structure form is under traditional Automobile Design platform, with the increase of power, ruler
Very little to become larger, design becomes difficult for taking turns interior limited bulk, if considering further that the system integration can become more in this condition
Add difficulty.
